Federal Register / Vol. 73, No. 51 / Friday, March 14, 2008 / Proposed Rules
All of the other tabs that we tested
performed reasonably well when fed
with tabs on the top, or on the left and
the right edges of the mailpiece. When
fed with tabs on the bottom,
performance was unacceptable.
Cover Stock
We tested 20- and 28-pound bond
cover stock. The heavier cover stock
performed better.
Other Characteristics Tested
Variations of size (5″ x 83⁄8″ and 6″ x
107⁄8″), tab location (top and ends as
specified in the Domestic Mail Manual,
section 201.3.0), and binding did not
have a significant effect on the test
results for the 1⁄16-inch-thick mailpieces.
Additional Mailpiece Characteristics
Other characteristics are known to be
important. These characteristics include
surface friction, static attraction, and
tear strength on the cover; tab adhesives;
tab application; and compatibility with
current letter trays (slim jims are more
sensitive to damage than regular
enveloped letters). We will provide new
standards for these characteristics in a
future proposed rule.

Machinable Letters
Once we complete the new standards
for booklets and folded self-mailers, we
plan to extend those standards to all
machinable letters. Booklets are
mailable at automation prices when
barcoded and tabbed or sealed.
However, booklets with the spine on the
bottom edge but without tabs are
currently allowed as machinable letters
when they are not barcoded. In the
future, we plan to allow nonbarcoded
booklets and folded self-mailers to be
mailed as machinable letters only if they
meet all of the mail preparation
requirements for automation letters.
This change will ensure efficient mail
processing for all letter-size booklets
and folded self-mailers.
Comments and Suggestions
We encourage mailers to send their
comments and suggestions on the
information provided in this notice. We
are especially asking mailers to suggest
any new or alternative booklet
construction techniques that will
improve machine performance on 1⁄8inch and 1⁄16-inch booklets. Suggestions
on tab adhesive are also appreciated.
We will continue to consult with the
mailing industry to develop and test the
mailing standards. For example, we
intend to investigate to what extent
pieces between 1⁄16-inch and 1⁄8-inchthick will process acceptably, whether
there is a (not-yet-tested) variety of

Jkt 214001
closure or configuration that will make
1⁄8-inch-thick pieces acceptable, and the
impact of lightweight pages or having
the spine on the short edge (i.e., the
leading edge).
In addition, since it may be difficult
for mailers to identify tabs with
appropriate materials, size, perforations,
and adhesives, we will investigate a
means to certify and mark acceptable
tabs. Perforation makes it difficult to
inspect tab strength. Perforated plastic
tabs are especially problematic, as they
raise additional issues with adhesive
bonding and leakage. We would
appreciate comments on the impact of
prohibiting perforated tabs until
certification procedures are developed.
Next Steps
Once our testing is completed and the
results are validated, we will publish a
proposed rule in the Federal Register,
with a request for comments on the
revised mailing standards. The revised
standards will not change the
preparation criteria for enveloped
letters. Fully enveloped pieces up to 1⁄4inch thick that meet automation
standards will continue to be accepted
at automation prices.

II. Background
On November 27, 2007, Indiana
submitted to EPA draft revised rules for
parallel processing as revisions to the
Indiana SIP for particulate matter,
measured as particles with an
aerodynamic diameter less than or equal
to ten microns in diameter (PM10).
Indiana provided additional materials,
dated December 3, 2007, in an
addendum to the November 27, 2007
submittal. Indiana submitted final, fully
adopted revised PM10 rules on February
21, 2008.
Indiana’s submittal consists of
revisions to 326 Indiana Administrative
Code (IAC) 6.5, Particulate Matter
Emission Limitations Except Lake
County; and 326 IAC 6.8, Particulate
Matter Emission Limitations For Lake
County. The revised rules include a
variety of changes to Indiana’s Federally
approved PM10 SIP rules, such as:
Updates to affected facilities’ names or
emission source identifiers; rule
formatting revisions which have no
effect on numerical emission limits; the
removal of emission limits for
individual emission units which no
longer exist or operate; and the removal
of rules for entire facilities which no
longer exist or which no longer operate
PO 00000
Frm 00020
Fmt 4702
Sfmt 4702
the PM10 sources that were listed in the
previous PM10 SIP. Indiana has
increased some PM10 emission limits
for sources in Clark, Dubois, Marion, St.
Joseph, and Lake Counties. Indiana has
also tightened PM10 emission limits at
several sources.
In addition, Indiana has relocated the
opacity limits and natural gas
combustion-only restrictions for its Lake
County sources to the facility-specific
sections of the rule. The PM10 limits
and any opacity limits and natural gasonly restrictions for each facility are
now grouped in a single section.
III.What has Indiana revised in 326
IAC 6.5?
Rule 326 IAC 6.5–1, General
Provisions, has not changed. The
facility-specific PM10 emission limits
for Clark, Dearborn, Dubois, Howard,
Marion, St. Joseph, Vanderburgh, Vigo,
and Wayne Counties, given in 326 IAC
6.5–2 through 326 IAC 6.5–10, have
been updated and revised, as discussed
below.
a. Clark County
There were eight facilities listed in
the previously approved SIP for Clark
County whose entries have been
removed from 326 IAC 6.5–2, due to
company shutdowns or the removal of
all PM10 emitting units. The eight
facilities are: B & E Asphalt (326 IAC
6.5–2–2); Colgate Palmolive (326 IAC
6.5–2–3); Gohman Asphalt (326 IAC
6.5–2–5); Hillerich and Bradsby (326
IAC 6.5–2–6); Hooker Chemical (326
IAC 6.5–2–7); Quality Paving (326 IAC
6.5–2–10); Robinson Foundry (326 IAC
6.5–2–11); and USS Agri Chemicals (326
IAC 6.5–2–12).
The numerical PM10 emission limits
for Essroc Cement Corporation, formerly
Essroc Materials (326 IAC 6.5–2–4), in
Clark County are unchanged from the
previously approved SIP. Their entry in
326 IAC 6.5–2 was only edited for
format consistency and the updated
facility name.
The new rule removed the emission
limits for the five million British
Thermal Units per hour (MMBtu/hr)
gas-oil boiler at PQ Corporation (326
IAC 6.5–2–9) in Clark County. That
boiler is no longer operating.
The previous entry for Kimball
Office—Borden, formerly Kimball Case
Goods (326 IAC 6.5–2–8), listed one oilfired boiler rated at 6 MMBtu/hr. The
revised rule lists two boilers, rated at 6.7
MMBtu/hr each, restricted to No. 2 fuel
oil. The original PM10 emission limits
of 0.3 tons per year (tpy) and 0.0130
pounds per million British Thermal
Units (lb/MMBtu) are unchanged. The
listed emission limits now apply to each
E:\FR\FM\14MRP1.SGM
14MRP1
Federal Register / Vol. 73, No. 51 / Friday, March 14, 2008 / Proposed Rules
boiler. Considering the higher boiler
rating of 6.7 MMBtu/hr as well, this
represents an increase in allowable SIP
emissions of approximately 2.3 pounds
per day. It should be noted that the final
revised rule inadvertently listed the lb/
MMBtu limit in units of gr/dscf. Indiana
is preparing to publish a correction
notice in the Indiana Register to remedy
the error and list the Kimball Office—
Borden emission limit as 0.0130 lb/
MMBtu. Indiana performed dispersion
modeling to show that these emission
limit increases would be protective of
the PM10 NAAQS. See Section V for a
discussion of the State’s modeling
analysis.
mstockstill on PROD1PC66 with PROPOSALS
b. Dearborn County
There were two facilities listed in the
previously approved SIP for Dearborn
County whose entries have been
removed from 326 IAC 6.5–3, due to
company shutdowns or the removal of
all PM10 emitting units. The two
facilities are Lotus Ware House (326 IAC
6.5–3–6) and Schenley Distillers,
Incorporated (326 IAC 6.5–3–9).
The numerical PM10 emission limits
for five facilities in Dearborn County are
unchanged from the previously
approved SIP. Their entries in 326 IAC
6.5–3 were only edited for format
consistency or name changes. The five
facilities are: Anchor Glass Container
Corporation, formerly Anchor Glass
(326 IAC 6.5–3–2); Dearborn Ready Mix,
LLC, formerly Dearborn Gravel (326 IAC
6.5–3–3); Indiana Michigan Power,
Tanners Creek Plant (326 IAC 6.5–3–4);
Laughery Gravel (326 IAC 6.5–3–5); and
Paul H. Rohe Company, Inc. (326 IAC
6.5–3–7).
For Lawrenceburg Distillers Indiana,
LLC, formerly Joseph E. Seagram and
Sons, Inc. (326 IAC 6.5–3–8) in
Dearborn County, the reference to Boiler
5 has been removed, because it is no
longer operating. The remaining
emission limits for this facility were not
changed.
c. Dubois County
There were seven facilities listed in
the previously approved SIP for Dubois
County whose entries have been
removed from 326 IAC 6.5–4, due to
company shutdowns or the removal of
all PM10-emitting units. The seven
facilities are: Hoosier Desk (326 IAC
6.5–4–7); Indiana Furniture Industries
(326 IAC 6.5–4–11); Jasper Cabinet No.
1 (326 IAC 6.5–4–12); Jasper Cabinet No.
2 (326 IAC 6.5–4–13); Jasper Cabinets
Corporation (326 IAC 6.5–4–14); Jasper
Veneer (326 IAC 6.5–4–22); and Jasper
Wood Products (326 IAC 6.5–4–23).
The numerical PM10 emission limits
for ten facilities in Dubois County are
VerDate Aug<31>2005
19:26 Mar 13, 2008
Jkt 214001
unchanged from the previously
approved SIP. Their entries in 326 IAC
6.5–4 were only edited for format
consistency or name changes. The ten
facilities are: Kimball Office—Jasper
15th Street, formerly Artec (326 IAC
6.5–4–2); DMI Furniture Plant No. 5,
formerly Dolly Madison Plant No. 5 (326
IAC 6.5–4–4); Dubois County Farm
Bureau Co-op (326 IAC 6.5–4–5); Forest
Products No. 1 (326 IAC 6.5–4–6);
Indiana Desk Company (326 IAC 6.5–4–
9); Jasper Desk Company, Incorporated
(326 IAC 6.5–4–16); Kimball Office—
Jasper Cherry Street, formerly Jasper
Laminates, Plant #1—Division of
Kimball (326 IAC 6.5–4–17); Jasper
Municipal Electric Utility (326 IAC 6.5–
4–18); Jasper Seating (326 IAC 6.5–4–
21); and Styline Industries, Inc. Plant #8
(326 IAC 6.5–4–24).
The revised rule does not change the
previous PM10 emission limits for
Indiana Dimension, Indiana Furniture
Industries, formerly Indiana Dimension
(326 IAC 6.5–4–10). However, the
revised rule adds a wood working-dust
collector emission limit of 0.4 tons per
year. This emission unit was previously
listed in the Indiana PM10 SIP at 326
IAC 6.5–4–8, in the entry for Indiana
Chair. The Indiana Chair facility has not
moved, but it is now part of Indiana
Dimension, Indiana Furniture
Industries, and its PM10 emission limits
have been added to 326 IAC 6.5–4–10.
The listing at 326 IAC 6.5–4–8 for
Indiana Chair has been removed from
the SIP.
The revised rule does not change the
previous PM10 emission limits for
JOFCO Inc. Plants 1 and 2, formerly
Jasper Office Furniture Co., Inc., Plant
#1 (326 IAC 6.5–4–19) in Dubois
County. However, the revised rule adds
an emission limit of 1.2 tons per year for
wood working. This PM10 emission
source and emission limit were
previously listed in the Indiana PM10
SIP at 326 IAC 6.5–4–20, in a separate
entry for Jasper Office Furniture. The
Jasper Office Furniture facility has not
moved, but it is now part of JOFCO,
Inc., and its PM10 emission limits have
been added to 326 IAC 6.5–4–19. The
listing at 326 IAC 6.5–4–20 for Jasper
Office Furniture has been removed from
the SIP.
For Jasper Seating Co., Inc., Plant No.
3, formerly Dolly Madison Plant No. 4
(326 IAC 6.5–4–3), the rating for the
wood-fired boiler has been corrected
from 5 MMBtu/hr to 10.5 MMBtu/hr.
The emission limits of 9.4 tpy and 0.60
lbs/MMBtu have not changed.
For Jasper Chair Company, Inc. (326
IAC 6.5–4–15), the rating for the wood
boiler has been corrected from 18
MMBtu/hr to 18.3 MMBtu/hr. The
PO 00000
Frm 00021
Fmt 4702
Sfmt 4702
13815
annual emission limit for that boiler
increased from 15.6 tpy to 15.77 tpy,
while the short-term limit of 0.60 lb/
MMBtu remained the same. The
emission limit for wood working
operations at this facility is unchanged.
Indiana performed dispersion
modeling to show that the emission
increases at Jasper Seating Co., Inc. and
Jasper Chair Company, Inc. would be
protective of the PM10 NAAQS. See
Section V for a discussion of the State’s
modeling analysis.
d. Howard County
There were nine facilities listed in the
previously approved SIP for Howard
County whose entries have been
removed from 326 IAC 6.5–5, due to
company shutdowns or the removal of
all PM10 emitting units. The nine
facilities are: Cuneo Press (326 IAC 6.5–
5–3); Greentown Grain (326 IAC 6.5–5–
6); Howard Co. Farm Bureau Co-op
(Greentown) (326 IAC 6.5–5–7); Howard
Co. Farm Bureau Co-op (Russiaville)
(326 IAC 6.5–5–8); Judson Feed & Grain
(326 IAC 6.5–5–9); Name, Inc. (326 IAC
6.5–5–12); Penn-Dixie; boilers (326 IAC
6.5–5–13); Penn-Dixie; furnaces (326
IAC 6.5–5–14), and Russiaville Feed &
Grain (326 IAC 6.5–5–15).
The numerical PM10 emission limits
for three facilities in Howard County are
unchanged from the previously
approved SIP. Their entries in 326 IAC
6.5–5 were only edited for format
consistency or name changes. The three
facilities are: Kokomo Grain Company
(326 IAC 6.5–5–10); E & B Paving, Inc.,
formerly Mohr Construction (326 IAC
6.5–5–11); and Martin Marietta
Materials, Inc., formerly Yeomen Stone
& Sand (326 IAC 6.5–5–16).
The new rule removes the entry for
two gas-fired boilers, Stack 2, at Delco
Electronics Corporation, formerly
Delphi Delco (326 IAC 6.5–5–5). The
boilers are no longer operating. The
remainder of 326 IAC 6.5–5–5 is
unchanged.
For Chrysler, LLC-Kokomo Casting
Plant and Kokomo Transmission Plant,
formerly Chrysler-Haynes (326 IAC 6.5–
5–2) in Howard County, the entries for
Reverberatory Furnaces D and E, both
92.5 tons per year, and Gas Boiler 3,
have been removed, because the units
are no longer operating. The revised rule
adds a listing for Boiler 5, restricted to
natural gas only, and an emission limit
of .75 lb/MMBtu for Boiler 4 at the
Chrysler, LLC-Kokomo Transmission
Plant. Boiler 4 burns reclaimed residual
oil or natural gas. Boilers 4 and 5 were
previously listed in the Indiana PM10
SIP at 326 IAC 6.5–5–4, in a separate
entry for DaimlerChrysler-U.S. 31. The
two boilers, along with Boilers 1, 2, and
E:\FR\FM\14MRP1.SGM

13816
Federal Register / Vol. 73, No. 51 / Friday, March 14, 2008 / Proposed Rules
mstockstill on PROD1PC66 with PROPOSALS
3 at the same facility, each had emission
limits of 0.75 lb/MMBtu and shared an
overall limit of 875.7 tpy in 326 IAC
6.5–5–4. The DaimlerChrysler-U.S. 31
facility, now known as the Chrysler,
LLC-Kokomo Transmission Plant, has
not moved, but its PM10 emission limits
have been included in 326 IAC 6.5–5–
2. Boilers 1, 2, and 3 have been shut
down and demolished. Boiler 4 retains
its original limit of 0.75 lb/MMBtu with
no tons-per-year limit. The listing at 326
IAC 6.5–5–4 for DaimlerChrysler-U.S.
31 has been removed from the SIP.
e. Marion County
The revised rule no longer contains
6.5–6–1(b), which provided that
‘‘sources shall be considered in
compliance with the tons per year
emission limits established in sections 2
through 36 of this rule if within five
percent (5%) of the emission limit.’’ The
removal of this provision strengthens
the SIP.
There were twenty-one facilities listed
in the previously approved SIP for
Marion County whose entries have been
removed from 326 IAC 6.5–6, due to
company shutdowns or the removal of
all PM10-emitting units. The 21
facilities are: Bridgeport Brass (326 IAC
6.5–6–4); Central State Hospital (326
IAC 6.5–6–6); Chevrolet (326 IAC 6.5–6–
7); Chrysler (El.) Shade (326 IAC 6.5–6–
8); Chrys. Fdy S. Tibbs (326 IAC 6.5–6–
9); Community Hospital (326 IAC 6.5–
6–10); Design Mix (326 IAC 6.5–6–11);
Farm Bureau (Fert.) (326 IAC 6.5–6–12);
FMC Bearing (326 IAC 6.5–6–13); FMC
Chain (326 IAC 6.5–6–14); Fort
Benjamin Harrison (326 IAC 6.5–6–16);
Glass Containers (326 IAC 6.5–6–17);
Indep. Concrete Pipe (326 IAC 6.5–6–
19); Indpls. Rubber Co. (326 IAC 6.5–6–

IAC 6.5–6–30); Richardson Co. (326 IAC
6.5–6–32); and Stokely Van Camp (326
IAC 6.5–6–36).
The numerical PM10 emission limits
for seven facilities in Marion County are
unchanged from the previously
approved SIP. Their entries in 326 IAC
6.5–6 were only edited for format
consistency or name changes. The seven
facilities are Allison Transmission (326
IAC 6.5–6–2); Bunge North America
(East), Inc., formerly Central Soya (326
IAC 6.5–6–5); Indiana Veneers
Corporation (326 IAC 6.5–6–22);

Sludge Incinerator, formerly Sludge
Incinerator (326 IAC 6.5–6–35).
The entry for Asphalt Materials, Inc.,
formerly Asph. Mat. & Const., Inc. (326
IAC 6.5–6–3), has been updated. The
PM10 emission limits formerly listed for
the Oxid. Tank are now listed for the
Asphalt Blowing Stills. The numerical
limits have not changed.
The PM10 emission limits for Citizens
Thermal Energy C.C. Perry K, formerly
IPL (326 IAC 6.5–6–23), have not
changed. A new rule section, 326 IAC
6.5–6–23.1, has been added for
Indianapolis Power and Light Company
(IPL) Harding Street Station. This
facility was formerly known as IPL
Stout. The emission limits for IPL Stout
were previously included with the
limits for IPL Perry K, now known as
Citizens Thermal Energy C.C. Perry K
(326 IAC 6.5–6–23). The PM10 SIP
emission limits for Indianapolis Power
and Light Company (IPL) Harding Street
Station, formerly IPL Stout, have not
changed.
The new rule removes individual unit
emission limits for three facilities in
Marion County. For Automotive
Components Holdings, LLCIndianapolis Plant, formerly Ford Motor
Co. (326 IAC 6.5–6–15), the entry for
Boiler 1 was removed. This unit is no
longer operating. For Cargill, Inc.,
formerly Cargill Dry Corn Ingredients,
Inc., formerly Illinois Cereal Mills,
Incorporated, (326 IAC 6.5–6–18), ten
emission units have been removed from
the rule, due to process shutdowns. No
other emission limits at the facility have
changed. For National Starch and
Chemical Company, formerly National
Starch (326 IAC 6.5–6–25), the entry for
Boiler 4 has been removed, because the
boiler is no longer operating. No other
PM10 emission limits at the facility
have changed.
For International Truck and Engine
Corporation & Indianapolis Casting
Corporation, formerly Navistar
International, (326 IAC 6.5–6–26), the
entry for the Phase 3 Baghouse has been
clarified to apply to the Phase 3 North
and South Baghouses. Indiana stated
that the baghouses vent through three
stacks of the same height, very near each
other. The emission limit, which applies
to the baghouses as a whole, has not
changed. This change is not expected to
impact the PM10 concentrations in the
vicinity of the facility. See Section V for
a discussion of the State’s analysis.
For Vertellus Agriculture and
Nutrition Specialties, LLC (Vertellus),
formerly Reilly Industries, Inc. (326 IAC
6.5–6–31), Indiana has stated that the
correct PM10 emission limits for the
186N and 2724W units were mistakenly
removed during a previous rule revision
PO 00000
Frm 00022
Fmt 4702
Sfmt 4702
(approved by EPA at 69 FR 5036,
February 3, 2004). The limits for the
2724W unit are reinstated in the revised
rule at 4.0 tpy and 0.15 lb/MMBtu. The
revised rule combines the reinstated
annual limit for the 186N unit (0.9 tpy)
with the unchanged annual limits for
the 2722W and 2726S units (3.5 and 7.8
tpy, respectively) into one 12.2 tpy
shared limit. This shared limit is
equivalent to the sum of the three
sources’ previous individual tons per
year limits. With this change, the 186N
unit increases its fuel limit slightly,
from 0.011 lb/MMBtu to 0.15 lb/
MMBtu. The fuel limits for the other
two sources are unchanged.
Also in the revised rule for Vertellus,
Unit 722804 is no longer restricted to
only burning natural gas, but its limits
of 0.2 tpy and 0.011 lb/MMBtu are not
changed. The emission limits for Unit
732714 have been decreased from 7.5
tpy to 2.7 tpy and from 0.15 lb/MMBtu
to 0.011 lb/MMBtu. In addition, the
112E boiler, listed in previous versions
of the PM10 SIP at 0.5 tpy and 0.15 lb/
MMBtu, is no longer listed in 326 IAC
6.5–6–31. It is a waste heat boiler which
performs no combustion and has no
PM10 emissions of its own. Indiana
performed dispersion modeling to show
that the revised emission limits at
Vertellus would lead to lower impacts
on air quality compared to the previous
emission limits. See Section V for a
discussion of the State’s modeling
analysis.
f. St. Joseph County
There were twelve facilities listed in
the previously approved SIP for St.
Joseph County whose entries have been
removed from 326 IAC 6.5–7, due to
company shutdowns or the removal of
all PM10 emitting units. The twelve
facilities are: Allied Signal Aerospace
(326 IAC 6.5–7–2); AM General (326
IAC 6.5–7–3); ARCO Engg. Const.
Corporation (326 IAC 6.5–7–4); Asphalt
Engineers (326 IAC 6.5–7–5); I & MTwin Branch (326 IAC 6.5–7–7);
Mishawaka Brass (326 IAC 6.5–7–8);
Northern Indiana Children’s Hospital
(326 IAC 6.5–7–9); Reliance ElectricDodge (326 IAC 6.5–7–12); Uniroyal
(326 IAC 6.5–7–15); Volney Felt Mills
(326 IAC 6.5–7–17); Wheelabrator Frye
(326 IAC 6.5–7–19), and White Farm
Equipment Company (326 IAC 6.5–7–
20).
The numerical PM10 emission limits
for three facilities in St. Joseph County
are unchanged from the previously
approved SIP. Their entries in 326 IAC
6.5–7 were only edited for format
consistency or name changes. The three
facilities are: Bosch Braking Systems
Corporation (326 IAC 6.5–7–6); Holy

Cross Services Corporation (Saint
Mary’s Campus) (326 IAC 6.5–7–13,
with recent revisions approved by EPA
on July 30, 2007, at 72 FR 41450); and
the University of Notre Dame du Lac
(326 IAC 6.5–7–16).
The new rule removes individual unit
emission limits for two facilities in St.
Joseph County. For RACO-Hubbell
Electric Products, formerly RACO (326
IAC 6.5–7–10), the entry for oil-fired
boiler nos. 1 and 2 have been removed.
These boilers no longer operate. The
remaining PM10 emission limits for this
facility are unchanged. For Accucast
Technology, LLC, formerly Sibley
Machine & Foundry (326 IAC 6.5–7–14),
the entries for the Cupola and the
Tumble Blast have been removed. These
units are no longer operating. The
remaining PM10 emission limits have
not changed. In the final revised rule,
Accucast’s PM10 emission limits were
inadvertently given with units of
pounds per million British Thermal
Units, which is incorrect. The emission
limits should be in grains per dry
standard cubic foot. A correction notice
was published in the Indiana Register
on February 5, 2008, to correct this
error.
For Reith Riley Construction
Company, Inc. (326 IAC 6.5–7–11), one
Rotary Dryer with limits of 11.10 tpy is
no longer operating and has been
removed from the rule. The other unit,
a Rotary Dryer with limits of 1.70 tpy
and 0.052 gr/dscf, has been replaced by
a Drum Mixer/Burner, with limits of
78.5 tpy and 0.03 gr/dscf. The PM10
limits for the Rotary Dryer at Walsh &
Kelly, Inc. (326 IAC 6.5–7–18) have
been increased from 20.48 tpy to 53.22
tpy. Indiana performed dispersion
modeling to show that these emission
limit increases would be protective of
the PM10 NAAQS. See Section V for a
discussion of the State’s modeling
analysis.
g. Vanderburgh County
The revised rule no longer contains
6.5–8–1(b), which provided that
‘‘compliance with the tons per year
limit shall be acceptable if within five
percent (5%) of the established tons per
year emission limit.’’ The removal of
this provision strengthens the SIP.
There were ten facilities listed in the
previously approved SIP for
Vanderburgh County whose entries have
been removed from 326 IAC 6.5–8, due
to company shutdowns or the removal
of all PM10–emitting units. The ten
facilities are: Bernadin (326 IAC 6.5–8–
2); Craddock Finishing (326 IAC 6.5–8–
3); Evv. State Hospital (326 IAC 6.5–8–
4); Evansville Veneer and Lumber (326
IAC 6.5–8–5); General Foods (326 IAC

6.5–8–8); Mead Johnson (326 IAC 6.5–
8–9); National of Evansville (326 IAC
6.5–8–10); and Whirlpool—Morgan
Avenue (326 IAC 6.5–8–15).
The numerical PM10 emission limits
for two facilities in Vanderburgh County
are unchanged from the previously
approved SIP. Their entries in 326 IAC
6.5–8 were only edited for format
consistency or name changes. The two
facilities are: Land O’Lakes Purina Feed
LLC, formerly Purina Mills, Inc. (326
IAC 6.5–8–12) and Southern Indiana
Gas and Electric Company, Broadway
Avenue Generating Station, formerly
SIGECO (326 IAC 6.5–8–13).
The new rule reduces or removes
individual unit emission limits for two
facilities in Vanderburgh County. For
Nunn Milling Company, Inc. (326 IAC
6.5–8–11), the entries and emission
limits for seven units have been
removed due to process shutdowns.
Only the hammer mill remains in the
SIP rule, with unchanged PM10
emission limits. For Whirlpool
Corporation Highway 41 North (326 IAC
6.5–8–14), boiler no. 2, formerly coalfired, is now required to use natural gas
only, and the PM10 emission limits for
boiler no. 2 have been removed from the
rule. This is consistent with Indiana’s
practice for other units in Indiana’s
previous natural gas rule, approved by
EPA on February 3, 2004, at 69 FR 5036.
Boiler no. 3, formerly coal-fired, and
boiler no. 5, formerly oil-fired, are now
each limited to natural gas with #2 fuel
oil backup. Their PM10 emission limits
are unchanged from the previous SIP.
The entry for boiler no. 4 has been
removed, as this unit is no longer
operating.
h. Vigo County
The revised rule no longer contains
6.5–9–1(b), which provided that
‘‘compliance with the tons per year
limit shall be acceptable if within five
percent (5%) of the established tons per
year emission limit.’’ The removal of
this provision strengthens the SIP.
There were twelve facilities listed in
the previously approved SIP for Vigo
County whose entries have been
removed from 326 IAC 6.5–9, due to
company shutdowns or the removal of
all PM10 emitting units. The twelve
facilities are: Alcan (326 IAC 6.5–9–2);
Columbian Home Products (326 IAC
6.5–9–3); Gartland Foundry (326 IAC
6.5–9–4); Indiana Gas and Chemical
(326 IAC 6.5–9–6); ISU (326 IAC 6.5–9–
7); J.I. Case (326 IAC 6.5–9–9); Rose

6.5–9–19); and Wabash Valley Asphalt
(326 IAC 6.5–9–20).
The numerical PM10 emission limits
for two facilities in Vigo County are
unchanged from the previously
approved SIP. Their entries in 326 IAC
6.5–9 were only edited for format
consistency or name changes. The two
facilities are S&G Excavating, Inc.,
formerly Martin Marietta (326 IAC 6.5–
9–10) and Ulrich Chemical, Inc. (326
IAC 6.5–9–17).
The new rule for Terre Haute Grain
(326 IAC 6.5–9–15) in Vigo County does
not change any PM10 emission limits.
However, the revised rule adds a 1.7 tpy
limit for drying and a 16.0 tpy limit for
handling. These emission units were
previously listed in the Indiana PM10
SIP at 326 IAC 6.5–9–5, in the entry for
Graham Grain. The Graham Grain
facility has not moved or changed, but
its PM10 emission limits have been
included in 326 IAC 6.5–9–15. The
separate listing at 326 IAC 6.5–9–5 for
Graham Grain has been removed from
the SIP.
The new rule reduces or removes
individual unit emission limits for two
facilities in Vigo County. For
International Paper Company (326 IAC
6.5–9–8), the entry for the no. 5 boiler
has been removed, because the boiler is
no longer operating. The PM10 limits
for the remaining units at this facility
are unchanged. For Sisters of
Providence (326 IAC 6.5–9–13), the no.
2 and 3 boilers are limited to natural gas
with fuel oil backup. The tons-per-year
limit for these boilers has been removed,
but the 20.52 pounds-per-hour (lb/hr)
limit for these boilers, which was
equivalent to the former tons-per-year
limit, has been retained. A limit of 0.341
lb/MMBtu has been added for the no. 2
and 3 boilers. The entry for the nos. 5,
7, and 8 boilers has been removed.
These units are no longer operating.
The PM10 emission limits for Duke
Energy Indiana, Inc.—Wabash River
Generating Station, formerly PSI (326
IAC 6.5–9–11), have not changed, but
the limits apply to fewer units than
previously. The limits used to cover
Units 1–6, but in the revised rule, the
same limits cover only Units 2–6. Unit
1 has not operated since 1994. Indiana
has stated that while the current annual
emission limit, 4102.3 tpy, was based
upon six operating units and should be
revised in a future rulemaking, the total
maximum possible emissions from the
five remaining units, at their full 0.1338
lb/MMBtu emission limits, would be
4017 tpy. Therefore, removing the
reference to Unit 1 does not result in an
increase in allowable PM10 emissions.

i. Wayne County
There were six facilities listed in the
previously approved SIP for Wayne
County whose entries have been
removed from 326 IAC 6.5–10, due to
company shutdowns or the removal of
all PM10 emitting units. The six
facilities are: Dana Perfect Circle
Richmond (326 IAC 6.5–10–7); Design &
Manufacturing (326 IAC 6.5–10–8);
Farmer’s Grain (326 IAC 6.5–10–10);
Schrock Cabinet Company (326 IAC
6.5–10–17); Wallace Metals (326 IAC
6.5–10–18); and Wayne County Farm
Bureau (326 IAC 6.5–10–19).
The numerical PM10 emission limits
for seven facilities in Wayne County are
unchanged from the previously
approved SIP. Their entries in 326 IAC
6.5–10 were only edited for format
consistency or name changes. The seven
facilities are: Barrett Paving Materials,
Inc. (326 IAC 6.5–10–2); Autocar LLC,
formerly Dana Perfect CircleHagerstown (326 IAC 6.5–10–6);
Earlham College (326 IAC 6.5–10–9);
Joseph H. Hill Co. (326 IAC 6.5–10–12);
Land O’Lakes Purina Feed LLC,
formerly Purina Mills, Inc. (326 IAC
6.5–10–13); Richmond Power & Light—
Whitewater Valley Generating Station
(326 IAC 6.5–10–15); and Richmond
State Hospital (326 IAC 6.5–10–16).
The new rule reduces or removes
individual unit emission limits for four
facilities in Wayne County. Previously,
there were two rules for Belden Wire
and Cable Company, 326 IAC 6.5–10–3
(office) and 326 IAC 6.5–10–4 (plant).
The revised PM10 SIP gives a single
entry for Belden Wire and Cable
Company at 326 IAC 6.5–10–3. There is
no longer a rule listing numbered 326
IAC 6.5–10–4. The revised rule for
Belden Wire and Cable Company retains
the emission limits for the plastic
compounding, rubber mixing, and
pneumatic processes from the former
rule 326 IAC 6.5–10–4. The entry and
emission limits for the oil boiler,
originally in 326 IAC 6.5–10–3, have
been removed, because the boiler is no
longer operating. For Milestone
Contractors LP (Cambridge City),
formerly Cambridge City Milestone
Contractors (326 IAC 6.5–10–5), the
previous listing for the rotary dryer now
applies to the drum dryer. The dryer’s
emission limits have decreased from
67.4 tpy to 45.74 tpy and from 0.218
grains per dry standard cubic foot (gr/
dscf) to 0.04 gr/dscf. For Johns Manville
International, Inc., formerly Johns
Manville Corporation (326 IAC 6.5–10–
11), two units are limited by the revised
rule to burn natural gas only, and their
numerical emission limits have been
removed from the SIP. This is consistent
VerDate Aug<31>2005
19:26 Mar 13, 2008
Jkt 214001
with Indiana’s practice for other natural
gas units. Four other units and their
emission limits have been entirely
removed from the rule. These units are
no longer operating. The PM10 emission
limits for the remaining two units in the
SIP, line 2 and line 3 forming and
collection, have not changed. For
Milestone Contractors Richmond,
formerly Richmond Milestone
Contractors (326 IAC 6.5–10–14), the
listing for the rotary dryer now applies
to the counter flow drum mixer, and the
emission limits have been reduced from
50.80 tpy to 46.76 tpy, and from 0.158
gr/dscf to 0.04 gr/dscf.
IV. What Has Indiana Revised in 326
IAC 6.8?
326 IAC 6.8 covers PM10 emissions at
facilities in Lake County. Rule 326 IAC
6.8–1, General Provisions, has been
updated to match the current rule
structure of 326 IAC 6.8. Rule 326 IAC
6.8–2 contains updated and revised
facility-specific PM10 emission limits.
The former rule 326 IAC 6.8–3, Lake
County: Opacity Limits; Exceptions to
326 IAC 5–1–2, has been repealed. Its
provisions have been placed in the
appropriate facility-specific sections of
326 IAC 6.8–2. There were minor
editorial changes to Rule 326 IAC 6.8–
4, Lake County: Opacity Limits; Test
Methods.
The former rule 326 IAC 6.8–5–1,
Lake County: Opacity Continuous
Emissions Monitors, has been repealed.
Its provisions have been placed in 326
IAC 6.8–2–1(e), and in the appropriate
facility-specific sections of 326 IAC 6.8–
2. The former rule 326 IAC 6.8–6, Lake
County: Combustion Sources; Natural
Gas, has been repealed. The sources
named in the former sections 326 IAC
6.8–6–2 through 326 IAC 6.8–6–20, have
been limited in the facility-specific
sections of the revised rule 326 IAC 6.8–
2 to natural gas combustion only,
without numerical PM10 emission
limits.
The former rule 326 IAC 6.8–7, Lake
County: Site-Specific Control
Requirements, has been repealed,
because most of its provisions were
outdated, referring to scheduled control
device installations or industrial unit
shutdowns which have already
occurred. The provisions which still
apply to Lake County sources have been
added to the appropriate facilityspecific sections of 326 IAC 6.8–2. Rule
326 IAC 6.8–8–1, Lake County:
Continuous Compliance Plan, has been
updated to reflect the current list of
applicable facilities.
The remainder of 326 IAC 6.8–8 is
unchanged. For Rule 326 IAC 6.8–9,
Lake County: PM10 Coke Battery
PO 00000
Frm 00024
Fmt 4702
Sfmt 4702
Emission Requirements, sections 6.8–9–
1 and 6.8–9–2 are unchanged. Section
6.8–9–3 has been amended to remove a
reference to Inland Steel (now known as
Mittal Steel—Indiana Harbor East Inc.).
The requirements referring to this
facility have been incorporated into the
facility’s entry at 326 IAC 6.8–2–17.
Rule 326 IAC 6.8–10–1, Lake County:
Fugitive Particulate Matter, has been
updated to reflect the current list of
applicable facilities. The remainder of
326 IAC 6.8–10 is unchanged. Rule 326
IAC 6.8–11, Lake County: Particulate
Matter Contingency Measures, is
unchanged.
Regarding the changes to 326 IAC 6.8–
2, there were six facilities listed in the
previously approved SIP for Lake
County that have been removed from
326 IAC 6.8–2, due to company
shutdowns or the removal of all PM10emitting units previously regulated
under the PM10 SIP. The six facilities
are: American Steel Foundries—East
Chicago (326 IAC 6.8–2–3); Associated
Box (326 IAC 6.8–2–5); General
Refractory (326 IAC 6.8–2–10); SCA
Tissue North America LLC, formerly
Georgia Pacific (326 IAC 6.8–2–11);
Globe Industries (326 IAC 6.8–2–12);
and Marport Smelting (326 IAC 6.8–2–
23).
The numerical PM10 emission limits
for fifteen facilities in Lake County are
unchanged from the previously
approved SIP. Their entries in 326 IAC
6.8–2 were only edited for format
consistency or name changes. The
fifteen facilities are: Bucko Construction
Company, Inc. (326 IAC 6.8–2–7); W.R.
Grace and Co.—Conn., formerly E. I.
Dupont (326 IAC 6.8–2–9); Hammond
Group, Inc.—Halstab Division (326 IAC
6.8–2–14); Jupiter Aluminum
Corporation (326 IAC 6.8–2–18);
Carmeuse Lime Inc., formerly
Marblehead Lime Company (326 IAC
6.8–2–22); Methodist Hospital Inc. (326
IAC 6.8–2–24); National Recovery
Systems (326 IAC 6.8–2–25); NIPSCo—
Dean H. Mitchell Station (326 IAC 6.8–
2–26); Premiere Candy Company (326
IAC 6.8–2–28); Reed Minerals—Plant
#14 (326 IAC 6.8–2–29); Rhodia, Inc.
(326 IAC 6.8–2–30); Smith Ready Mix,
Inc. (326 IAC 6.8–2–32); State Line
Energy, LLC (326 IAC 6.8–2–33);
Huhtamaki Foodservice, Inc., formerly
The Chinet Company (326 IAC 6.8–2–
34); and Union Tank Car Company,
Plant 1 (326 IAC 6.8–2–36).
The PM10 emission limits for U.S.
Steel—Gary Works (326 IAC 6.8–2–38)
have not changed. The opacity limits for
U.S. Steel—Gary Works in 326 IAC 6.8
are also unchanged, but they have been
relocated to 326 IAC 6.8–2–38(b). These
facility-specific opacity limits take

14MRP1
mstockstill on PROD1PC66 with PROPOSALS
Federal Register / Vol. 73, No. 51 / Friday, March 14, 2008 / Proposed Rules
precedence over the limits in Indiana’s
opacity regulations at 326 IAC 5–1–2.
For Silgan Containers Manufacturing
Corporation (326 IAC 6.8–2–31), the
previous PM10 SIP contained an
emission limit for a stack serving three
incinerator units. The listing in 326 IAC
6.8–2–31 for that stack has been revised
to apply to ‘‘Two (2) stacks serving an
incinerator (1 unit),’’ with the previous
PM10 emission limits of 0.007 lbs/
MMBTU and 0.310 lbs/hr unchanged.
However, according to IDEM, the
company’s October 2007 State-issued
operating permit indicates that the
single incinerator now vents to only one
stack. The other PM10 emission limits
for this facility are unchanged.
The new rule removes individual unit
emission limits for eight facilities in
Lake County. For Cargill, Inc., formerly
Cerestar USA, Inc. (326 IAC 6.8–2–8),
twenty-six PM10 emission limits have
been removed, due to process
shutdowns. The other PM10 emission
limits for this facility are unchanged.
The limits for Hammond Group, Inc.
(HGI)—Expander Division, formerly at
326 IAC 6.8–2–15, have been combined
with that of Hammond Group, Inc.
(HGI)—Halox Division, formerly at 326
IAC 6.8–2–13, resulting in the revised
rule 326 IAC 6.8–2–13, now titled
Hammond Group, Inc. (HGI) Halox
Division, Lead Products Division, and
Hammond Expander Division. The entry
for the Expander Division Stack 1–S–54
has been removed because PM10 is no
longer emitted from that stack. The
other PM10 emission limits for the
Halox Division and Expander Division
of this facility are unchanged. The
listing numbered 326 IAC 6.8–2–15 has
been removed from the SIP.
For Mittal Steel—Indiana Harbor East
Inc., formerly Inland Steel (326 IAC 6.8–
2–17), previously listed PM10 emission
limits have been removed for 15 units
which are no longer operating. The
PM10 emission limits for Blending
system baghouse B have also been
removed, because the baghouse was
never constructed. The other PM10
emission limits for this facility are
unchanged. The opacity limits for this
facility in 326 IAC 6.8 are not changed,
but they have been relocated to 326 IAC
6.8–2–17(b). These facility-specific
opacity limits take precedence over the
limits in Indiana’s opacity regulations at
326 IAC 5–1–2.
For Dover Chemical Corporation—
Hammond, formerly Keil Chemical—
Division of Ferro Corporation (326 IAC
6.8–2–19), the PM10 emission limits for
Pyro-chek 68PB1 of 0.052 lbs/ton and
0.030 lbs/hr and the PM10 limits for
Pyro-chek 77PB2 of 0.122 lbs/ton and
0.040 lbs/hr have been removed because

the units are no longer operating. The
other PM10 emission limits for this
facility are unchanged.
For Mittal Steel—Indiana Harbor West
Inc., formerly LTV Steel Corporation
(326 IAC 6.8–2–21), the PM10 limits for
Utility Boiler number 3 and Utility
boiler number 4 have been removed
because the boilers are no longer
operating. The previous PM10 limits
were 0.066 lbs/MMBTU and 12.85
lbs/hr for each boiler. The other PM10
emission limits for this facility are
unchanged. The opacity limits for this
facility in 326 IAC 6.8 are not changed,
but they have been relocated to 326 IAC
6.8–2–21(b). These facility-specific
opacity limits take precedence over the
limits in Indiana’s opacity regulations at
326 IAC 5–1–2.
For Praxair Inc. (326 IAC 6.8–2–27),
the PM10 emission limits of 42.5 lbs/ton
and 0.340 lbs/hr for the cylinder paint
spray booth, stack 033; the limits of 42.5
lbs/ton and 0.340 lbs/hr for the drum
paint spray booth, stack 073; and the
limits of 0.004 gr/dscf and 0.042 lbs/hr
for the cylinder shotblaster number 2
baghouse, stack 030, have all been
removed because the units are no longer
operating. The other PM10 emission
limits for this facility are unchanged.
For Conopco, Inc. d/b/a Unilever HPC
USA, formerly listed as Unilever HPC
USA (326 IAC 6.8–2–35), sixteen
emission units have been removed from
the rule because they are no longer
operating. These removals lower the
facility’s total allowable PM10
emissions by approximately 25 pounds
per hour. The other PM10 emission
limits for this facility are unchanged.
For the United States Gypsum
Company (326 IAC 6.8–2–37), the PM10
emission limits for the following have
been removed, due to process
shutdowns, for a total reduction of
about 1.38 lb/hr: rail car unloading,
stack J10; the Franklin fiber process,
stack M6; wallboard end sawing, Stack
B2; and the panel saw process. The
other PM10 emission limits for this
facility are unchanged.
At BP Products North America, Inc.—
Whiting Refinery (BP) (326 IAC 6.8–2–
6), many emission units currently burn
natural gas or refinery gas. Several
sources at BP were previously allowed
to burn fuel oil, but are now limited to
natural gas or refinery gas under the
revised rule. In this rule, all gas-burning
units are given revised emission limits
that reflect the most current EPA PM10
emission factor for gas combustion
provided in AP–42. Refinery gas is
considered to have similar PM10
emissions to natural gas. The emission
limits, 0.0075 lb/MMBtu, are higher
than the previous gas combustion

emission limits, which were 0.004 lb/
MMBtu. The previous emission limits
were also based on EPA emission
factors, but they only included filterable
PM10, which is emitted directly from
the stacks as solid or liquid particulate
matter. The newer factor includes both
filterable PM10 and condensable PM10,
which is emitted from the stacks as hot
gases or vapor, and which later cools
and condenses into aerosol droplets,
also treated as PM10. The emission test
methods for compliance determinations
at BP are revised to require the
measurement of both filterable and
condensable particulate. The new limit
better quantifies the total PM10 emitted
from natural gas combustion.
Emission limits are also given in
pounds per hour for most sources at BP;
these are adjusted to account for the
revised gas combustion emission
estimates. Although the numerical
limits have increased, the actual PM10
emissions at the gas combusting sources
are not expected to change, because the
units will still be using the same fuel as
before. Actual PM10 emissions will
decrease at those sources which were
previously allowed to burn fuel oil but
are now using only natural gas and
refinery gas. Eleven units which have
been shut down were removed from the
rule. Overall, the allowable PM10
emissions at BP decrease by 477 tpy
under the revised rule.
ASF—Keystone, Inc.—Hammond
(ASF—Keystone), formerly American
Steel Foundry—Hammond (326 IAC
6.8–2–4), no longer operates Tub
Grinder number 3–0388, and its limits
are removed from 326 IAC 6.8–2–4.
Several spring grinder units at ASF—
Keystone now vent to a control device
with a single stack; therefore, their
emission limits have been combined
into a single emission limit for the stack.
For Resco Products, Inc., formerly
Harbison Walker Refractories,
Hammond Works (326 IAC 6.8–2–16),
an emission limit of 0.0330 lb/ton and
0.460 lb/hr originally applied to two
mixers venting to one stack (D–5). The
two mixers now vent to separate stacks
(D–5 and D–14), so the original limit
was split into two separate limits of
0.0165 lb/ton and 0.230 lb/hr. The
newly added limit for Resin-bonded
materials handling, batching and
pressing at Stack D–12A represents a
combination of the former emission
limits for the magnesite auxiliary
milling system (Stack D–14), the
magnesite smooth roll crusher system
(D–15), and the specialty magnesite
handling system (D–16). The new limit,
which equals the sum of the three
former limits, is 0.25 lb/ton and 0.93
lb/hr. The previous entry for Chrome

Ore screening and milling, Stack D–12,
with limits of 0.078 lb/ton and 1.24 lb/
hr, has been removed from 326 IAC 6.8–
2–16, because the process has been shut
down. Overall, these changes represent
an emissions decrease of 1.24 lb/hr.
LaSalle Steel Company (LaSalle Steel)
(326 IAC 6.8–2–20) petitioned Indiana
for higher emission limits on its shot
blasting operation. LaSalle Steel was
unable to comply with its PM10 SIP
limits using its control device, a
baghouse, installed in 1992. According
to Indiana, the original 0.02 lb/hr
emission limit should have been 0.02
grains per actual cubic foot (based on
the baghouse manufacturer’s guarantee).
That rate corresponds to 2.57 lb/hr and
0.086 pounds per ton. Indiana revised
LaSalle’s shot blasting limits from 0.02
lb/hr to 2.57 lb/hr and 0.001 lb/ton to
0.086 lb/ton, which is more consistent
with the equipment guarantee.
Indiana performed dispersion
modeling to show that the emission
limit changes at BP, ASF Keystone,
Resco, and LaSalle Steel would still be
protective of the PM10 NAAQS. See
Section V for a discussion of the State’s
modeling analysis.
V. PM10 Modeling Analyses
To demonstrate that any increases in
PM10 emission limits within 326 IAC
6.5 and 326 IAC 6.8 would still be
protective of the PM10 NAAQS, Indiana
performed dispersion modeling. Indiana
used the AERMOD regulatory
dispersion model, version 07026, to
evaluate the impacts of the increased
PM10 limits in the revised rules. Five
years of representative local surface and
upper air National Weather Service data
were used in each AERMOD analysis.
Indiana used the AERMET
meteorological data processor, version
06341, a part of the AERMOD modeling
system, to prepare the surface
meteorological data and vertical
profiles, using the seasonal surface
characteristics at each surface
meteorological data site. Indiana used
the Building Profile Input Program
(BPIP), version 04274, to prepare wind
direction-specific building dimension
data for each source. This program also
calculates downwash inputs for the
Plume Rise Model Enhancements
(PRIME) algorithm in AERMOD.
Receptors were placed along facility
fencelines and in a grid pattern
surrounding the source area, with grid
receptors 100 meters apart, in
accordance with EPA guidance. The
AERMAP preprocessor, version 06341, a
part of the AERMOD modeling system,
was used to assign the elevations for all
sources, buildings, and receptors from
topographical data.

Jkt 214001
Because of their inherently low
emissions, many natural gas sources do
not have numerical emission limits in
the revised PM10 rules. Nonetheless,
current EPA emission factors were used
to model the PM10 emissions from all
modeled natural gas combustion units.
Background concentrations taken
from local air quality monitoring data
were added to the AERMOD results to
account for the contribution from
distant sources or very small local
sources that are typically not explicitly
included in the modeling analyses.
For some applications, Indiana
performed preliminary screening
modeling using the SCREEN3 model,
which gives a conservative 1-hour
average concentration for single sources.
Conversion factors were used to
estimate 24-hour and annual average
concentration values from the SCREEN3
results.
a. Clark County
The revised rule for Kimball Office—
Borden, formerly Kimball Case Goods
(326 IAC 6.5–2–8), added a second
boiler and slightly increased both
boilers’ listed MMBtu/hr ratings.
Indiana ran the SCREEN3 screening
model for the resulting 0.096 lb/hr
increase in allowable PM10 emissions.
The maximum SCREEN3 result was 0.36
micrograms per cubic meter (µg/m3) on
a 24-hour average and 0.07 µg/m3 on an
annual average. These levels are not
generally considered likely to cause or
significantly contribute to a modeled
exceedance of the PM10 NAAQS of 150
µg/m3 (24-hour average) and 50 µg/m3
(annual average). We consider the
Kimball Office-Borden rule revision to
be approvable.
b. Dubois County
The revised rule changes the PM10
emission limits for sources at Jasper
Seating Co., Inc., Plant No. 3 (326 IAC
6.5–4–3), and Jasper Chair Company,
Inc. (326 IAC 6.5–4–15). Indiana ran
SCREEN3 for the emission changes at
these sources. The SCREEN3 results
showed that the changes at Jasper
Seating Co., Inc. had an impact of 1.7
µg/m3 on a 24-hour average and 0.3 µg/
m3 on an annual average. Jasper Chair
Company, Inc.’s emission changes had
an impact of 0.27 µg/m3 on a 24-hour
average and 0.05 µg/m3 on an annual
average. PM10 concentration increases
of this size are generally considered to
be unlikely to cause or contribute to
exceedances of the PM10 NAAQS.
Indiana also used the AERMOD
model to evaluate Dubois County’s full
PM10 emissions. The AERMOD run
included 23 Dubois County facilities.
Surface meteorological data was taken
PO 00000
Frm 00026
Fmt 4702
Sfmt 4702
from Evansville, Indiana and upper air
data was taken from Peoria, Illinois, for
the five-year period of 1988 to 1992. The
high, second high 24-hour modeled
concentration was 26.8 µg/m3, and with
the background value of 50.7 µg/m3, the
final result was 77.5 µg/m3, compared to
the 24-hour NAAQS of 150 µg/m3. The
maximum annual modeled
concentration was 3.71 µg/m3, and with
the annual background concentration of
26.0, the final result was 29.7 µg/m3,
compared to the annual PM10 NAAQS
of 50 µg/m3. Therefore, the PM10
NAAQS should be protected under the
revised rule, and the revised PM10
emission limits are approvable.
c. Marion County
For International Truck and Engine
Corporation & Indianapolis Casting
Corporation, formerly Navistar
International, (326 IAC 6.5–6–26), the
rule was revised to reflect the fact that
there are three exhaust stacks that vent
the Phase 3 Baghouse emissions. The
three stacks have the same heights, and
are within 10 to 15 feet of each other.
Since the vents are so close to each
other and similar in size, EPA does not
expect that a dispersion modeling
analysis would show an appreciable
difference between the results of
modeling the full emissions from one
stack (as the previous rule indicated)
and the results of modeling one third of
the full emissions from each of the three
stacks (as the revised rule indicates).
Therefore, EPA did not require Indiana
to perform additional modeling for the
revised rule for International Truck and
Engine Corporation & Indianapolis
Casting Corporation (326 IAC 6.5–6–26).
For the analysis of the emission limit
changes at Vertellus, Indiana performed
dispersion modeling for the facility’s
emission limit changes alone, to
evaluate their impact. The AERMOD
analysis used surface meteorological
data from Indianapolis, Indiana, and
upper air data from Dayton, Ohio, for
the five-year period of 1988 to 1992.
Indiana modeled the previous and
revised PM10 limits separately for the
Vertellus units affected by the revised
rule. The high, second high modeled 24hour average PM10 concentration
decreased from 21.1 µg/m3 to 14.5
µg/m3 under the rule revision. The
maximum modeled annual average
PM10 concentration decreased from
1.07 µg/m3 to 0.96 µg/m3.
Indiana also noted that the closed
Chrysler Foundry, formerly listed at 326
IAC 6.5–6–9, was immediately north of
Vertellus. Its closure reduces the
allowable PM10 emissions in the
Marion County SIP by more than 160
tpy. Indiana used AERMOD to evaluate
E:\FR\FM\14MRP1.SGM
14MRP1
Federal Register / Vol. 73, No. 51 / Friday, March 14, 2008 / Proposed Rules
the impact of the Chrysler Foundry
shutdowns near Vertellus. At Vertellus’
peak receptor locations, the Chrysler
Foundry shutdowns would provide a
33.4 µg/m3 24-hour average reduction
and a 2.8 µg/m3 annual average
reduction. Chrysler Foundry’s modeled
reductions are greater than 33.4 µg/m3 at
several other nearby receptor locations,
and modeled reductions from Chrysler
Foundry that are comparable to
Vertellus’ modeled impacts occur over a
large area. EPA accepts Indiana’s
demonstration that the Chrysler
Foundry closure helps offset the
emission changes at Vertellus.

d. St. Joseph County
Indiana used AERMOD to evaluate
the emission limit changes at the ReithRiley and Walsh & Kelly facilities. A
total of 55 sources in St. Joseph County
were included in the analysis. The
analysis used surface meteorological
data from South Bend, Indiana and
upper air data from Peoria, Illinois for
the five-year period of 1988 to 1992.
Receptors were placed in grids centered
around the Reith-Riley and Walsh &
Kelly facilities. The maximum high,
second high 24-hour concentration,
which occurred near Walsh & Kelly, was
19.0 µg/m3. With a background
concentration of 40.3 µg/m3, the final
result was 59.3 µg/m3, compared to the
24-hour NAAQS of 150 µg/m3. The
maximum annual PM10 concentration,
which also occurred near Walsh &
Kelly, was 1.8 µg/m3. With a
background concentration of 23.0
µg/m3, the final result was 24.8 µg/m3,
compared to the annual PM10 NAAQS
of 50 µg/m3. Therefore, the PM10
NAAQS should be protected under the
revised rule, and the revised PM10
emission limits are approvable.
e. Lake County
Since only four facilities had
increasing emission limits, Indiana
focused its modeling analysis on those
sources. EPA modeling guidance does
not require an individual impact
analysis for sources with no SIP
emission limit changes, or with
emission limit decreases only. First,
Indiana modeled the increasing and
decreasing units at BP, to gauge the
impact of the emission limit changes.
Generally, a 24-hour average PM10
concentration below 5 µg/m3 or an
annual average PM10 concentration
below 1 µg/m3, would not be considered
to make a significant contribution to
overall PM10 concentrations. The
maximum 24-hour impact from the BP
changes was 0.48 µg/m3, and the
maximum annual impact from the BP
changes was 0.0 µg/m3.
VerDate Aug<31>2005
19:34 Mar 13, 2008
Jkt 214001
Indiana then separately modeled each
of the four Lake County facilities’ entire
PM10 emissions, with receptors placed
in each facility’s region of influence.
The maximum 24-hour impact from BP
was 5.3 µg/m3, and the maximum
annual impact was 0.94 µg/m3. The
maximum 24-hour impact from ASF—
Keystone was 58.4 µg/m3, and the
maximum annual impact was 11.9
µg/m3. The maximum 24-hour impact
from Resco was 50.8 µg/m3, and the
maximum annual impact was 9.7 µg/m3.
The maximum 24-hour impact from
LaSalle Steel was 26.2 µg/m3, and the
maximum annual impact was 6.2 µg/m3.
Finally, Indiana ran the AERMOD
model with all Lake County PM10
sources included. The receptor grid for
this analysis covered the areas which
were influenced by BP, ASF—Keystone,
Resco, and LaSalle Steel. Background
concentrations were added to the
AERMOD results, and the sums were
compared to the 24-hour PM10 NAAQS
of 150 µg/m3 and the annual PM10
NAAQS of 50 µg/m3. The maximum 24hour concentration near BP from all
sources, plus background, was 145.7
µg/m3, and the annual concentration
near BP, including background, was
46.8 µg/m3. These concentrations were
also the overall maximum
concentrations in the PM10 modeled
analysis for the Lake County facilities.
The maximum 24-hour concentration
near ASF—Keystone from all sources,
plus background, was 101.4 µg/m3, and
the annual concentration near ASF—
Keystone, including background, was
39.9 µg/m3. The maximum 24-hour
concentration near Resco from all
sources, plus background, was 84.8
µg/m3, and the annual concentration
near Resco, including background, was
40.3 µg/m3. The maximum 24-hour
concentration near LaSalle Steel from
all sources, plus background, was 76.5
µg/m3, and the annual concentration
near LaSalle Steel, including
background, was 35.1 µg/m3. The
analysis showed that the revised
emission limits at BP, ASF—Keystone,
Resco, and LaSalle Steel should be
protective of the PM10 NAAQS in Lake
County.
VI. What Action Is EPA Taking Today?
EPA is proposing to approve Indiana’s
February 21, 2008, PM10 SIP revision
request. This submittal includes
revisions to 326 IAC 6.5–2, 326 IAC 6.5–

IAC 6.8–5, 326 IAC 6.8–6, and 326 IAC
6.8–7, which EPA is proposing to
approve.
The following portions of 326 IAC 6.5
and 6.8 were unchanged by the
February 20, 2008, Indiana Register
publication, and therefore they remain a
part of the approved Indiana PM10 SIP:

As noted above, EPA is taking
comment on this proposed action. All
adverse comments submitted during the
comment period will be responded to in
EPA’s final action on this SIP revision.
If comments are received that preclude
EPA from rulemaking on portions of the
state submittal, EPA will proceed with
rulemaking on other portions of the
submittal that are not the subject of
these comments.
VII. Statutory and Executive Order
Reviews
Executive Order 12866: Regulatory
Planning and Review
Under Executive Order 12866 (58 FR
51735, September 30, 1993), this action
is not a ‘‘significant regulatory action’’
and therefore is not subject to review by
the Office of Management and Budget.
Paperwork Reduction Act
This proposed rule does not impose
an information collection burden under
the provisions of the Paperwork
Reduction Act of 1995 (44 U.S.C. 3501

Regulatory Flexibility Act
This proposed action merely proposes
to approve state law as meeting Federal
requirements and imposes no additional
requirements beyond those imposed by
state law. Accordingly, the
Administrator certifies that this
proposed rule will not have a significant
economic impact on a substantial
number of small entities under the
Regulatory Flexibility Act (5 U.S.C. 601
et seq.).
Unfunded Mandates Reform Act
Because this rule proposes to approve
pre-existing requirements under state
law and does not impose any additional
enforceable duty beyond that required
by state law, it does not contain any
unfunded mandate or significantly or
uniquely affect small governments, as

Executive Order 13132: Federalism
This action also does not have
Federalism implications because it does
not have substantial direct effects on the
states, on the relationship between the
national government and the states, or
on the distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132 (64 FR 43255,
August 10, 1999). This action merely
proposes to approve a state rule
implementing a federal standard, and
does not alter the relationship or the
distribution of power and
responsibilities established in the Clean
Air Act.
Executive Order 13175: Consultation
and Coordination With Indian Tribal
Governments
This proposed rule also does not have
tribal implications because it will not
have a substantial direct effect on one or
more Indian tribes, on the relationship
between the Federal Government and
Indian tribes, or on the distribution of
power and responsibilities between the
Federal Government and Indian tribes,
as specified by Executive Order 13175
(65 FR 67249, November 9, 2000).
Executive Order 13045: Protection of
Children From Environmental Health
and Safety Risks
This proposed rule also is not subject
to Executive Order 13045 ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997), because it proposes
approval of a state rule implementing a
Federal Standard.

National Technology Transfer
Advancement Act
Section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (NTTAA), 15 U.S.C. 272,
requires Federal agencies to use

such standards are not inconsistent with
VerDate Aug<31>2005

applicable law or otherwise impractical.
In reviewing SIP submissions, EPA’s
role is to approve state choices,
provided that they meet the criteria of
the Clean Air Act. Absent a prior
existing requirement for the state to use
voluntary consensus standards, EPA has
no authority to disapprove a SIP
submission for failure to use such
standards, and it would thus be
inconsistent with applicable law for
EPA to use voluntary consensus
standards in place of a program
submission that otherwise satisfies the
provisions of the Clean Air Act.
Therefore, the requirements of section
12(d) of the NTTAA do not apply.

Outer Continental Shelf Air
Regulations Update To Include New

Environmental Protection
Agency (EPA).
ACTION: Proposed rule.
AGENCY:
SUMMARY: EPA is proposing to update a
portion of the Outer Continental Shelf
(OCS) Air Regulations. Requirements
applying to OCS sources located within
25 miles of States’ seaward boundaries
must be promulgated into part 55 and
updated periodically to remain
consistent with the requirements of the
corresponding onshore area (COA), as
mandated by section 328(a)(1) of the
Clean Air Act (CAA). The portion of the
OCS air regulations that is being
updated pertains to the requirements for
OCS sources in the State of New York.
The intended effect of approving the
OCS requirements for the State of New
York is to regulate emissions from OCS
sources in accordance with the
requirements onshore. The requirements
discussed below are proposed to be
incorporated by reference into the Code
of Federal Regulations and are listed in
the appendix to the OCS air regulations.

Approval and Promulgation of Air Quality Implementation Plans;
Indiana; Revisions to Particulate Matter Rules
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: On November 27, 2007, Indiana submitted draft revisions to its
particulate matter State Implementation Plan (SIP) for sources in
Clark, Dearborn, Dubois, Howard, Lake, Marion, St. Joseph, Vanderburgh,
Vigo, and Wayne Counties. Indiana supplemented its submittal with a
public hearing transcript and additional technical support documents on
December 3, 2007, and submitted final, fully adopted revised rules on
February 21, 2008. This SIP revision updates facility names, revises
formatting, removes sources no longer in operation, and revises some
emission limits. Where emission limits increase, the State has included
air quality modeling analyses that demonstrate that air quality will
continue to be protected. EPA is proposing to approve this SIP revision
request.

II. Background
On November 27, 2007, Indiana submitted to EPA draft revised rules
for parallel processing as revisions to the Indiana SIP for particulate
matter, measured as particles with an aerodynamic diameter less than or
equal to ten microns in diameter (PM10). Indiana provided additional
materials, dated December 3, 2007, in an addendum to the November 27,
2007 submittal. Indiana submitted final, fully adopted revised PM10
rules on February 21, 2008.
Indiana's submittal consists of revisions to 326 Indiana
Administrative Code (IAC) 6.5, Particulate Matter Emission Limitations
Except Lake County; and 326 IAC 6.8, Particulate Matter Emission
Limitations For Lake County. The revised rules include a variety of
changes to Indiana's Federally approved PM10 SIP rules, such as:
Updates to affected facilities' names or emission source identifiers;
rule formatting revisions which have no effect on numerical emission
limits; the removal of emission limits for individual emission units
which no longer exist or operate; and the removal of rules for entire
facilities which no longer exist or which no longer operate the PM10
sources that were listed in the previous PM10 SIP. Indiana has
increased some PM10 emission limits for sources in Clark, Dubois,
Marion, St. Joseph, and Lake Counties. Indiana has also tightened PM10
emission limits at several sources.
In addition, Indiana has relocated the opacity limits and natural
gas combustion-only restrictions for its Lake County sources to the
facility-specific sections of the rule. The PM10 limits and any opacity
limits and natural gas-only restrictions for each facility are now
grouped in a single section.
III.What has Indiana revised in 326 IAC 6.5?
Rule 326 IAC 6.5-1, General Provisions, has not changed. The
facility-specific PM10 emission limits for Clark, Dearborn, Dubois,
Howard, Marion, St. Joseph, Vanderburgh, Vigo, and Wayne Counties,
given in 326 IAC 6.5-2 through 326 IAC 6.5-10, have been updated and
revised, as discussed below.
a. Clark County
There were eight facilities listed in the previously approved SIP
for Clark County whose entries have been removed from 326 IAC 6.5-2,
due to company shutdowns or the removal of all PM10 emitting units. The
eight facilities are: B & E Asphalt (326 IAC 6.5-2-2); Colgate
Palmolive (326 IAC 6.5-2-3); Gohman Asphalt (326 IAC 6.5-2-5);
Hillerich and Bradsby (326 IAC 6.5-2-6); Hooker Chemical (326 IAC 6.5-
2-7); Quality Paving (326 IAC 6.5-2-10); Robinson Foundry (326 IAC 6.5-
2-11); and USS Agri Chemicals (326 IAC 6.5-2-12).
The numerical PM10 emission limits for Essroc Cement Corporation,
formerly Essroc Materials (326 IAC 6.5-2-4), in Clark County are
unchanged from the previously approved SIP. Their entry in 326 IAC 6.5-
2 was only edited for format consistency and the updated facility name.
The new rule removed the emission limits for the five million
British Thermal Units per hour (MMBtu/hr) gas-oil boiler at PQ
Corporation (326 IAC 6.5-2-9) in Clark County. That boiler is no longer
operating.
The previous entry for Kimball Office--Borden, formerly Kimball
Case Goods (326 IAC 6.5-2-8), listed one oil-fired boiler rated at 6
MMBtu/hr. The revised rule lists two boilers, rated at 6.7 MMBtu/hr
each, restricted to No. 2 fuel oil. The original PM10 emission limits
of 0.3 tons per year (tpy) and 0.0130 pounds per million British
Thermal Units (lb/MMBtu) are unchanged. The listed emission limits now
apply to each
[[Page 13815]]
boiler. Considering the higher boiler rating of 6.7 MMBtu/hr as well,
this represents an increase in allowable SIP emissions of approximately
2.3 pounds per day. It should be noted that the final revised rule
inadvertently listed the lb/MMBtu limit in units of gr/dscf. Indiana is
preparing to publish a correction notice in the Indiana Register to
remedy the error and list the Kimball Office--Borden emission limit as
0.0130 lb/MMBtu. Indiana performed dispersion modeling to show that
these emission limit increases would be protective of the PM10 NAAQS.
See Section V for a discussion of the State's modeling analysis.
b. Dearborn County
There were two facilities listed in the previously approved SIP for
Dearborn County whose entries have been removed from 326 IAC 6.5-3, due
to company shutdowns or the removal of all PM10 emitting units. The two
facilities are Lotus Ware House (326 IAC 6.5-3-6) and Schenley
Distillers, Incorporated (326 IAC 6.5-3-9).
The numerical PM10 emission limits for five facilities in Dearborn
County are unchanged from the previously approved SIP. Their entries in
326 IAC 6.5-3 were only edited for format consistency or name changes.
The five facilities are: Anchor Glass Container Corporation, formerly
Anchor Glass (326 IAC 6.5-3-2); Dearborn Ready Mix, LLC, formerly
Dearborn Gravel (326 IAC 6.5-3-3); Indiana Michigan Power, Tanners
Creek Plant (326 IAC 6.5-3-4); Laughery Gravel (326 IAC 6.5-3-5); and
Paul H. Rohe Company, Inc. (326 IAC 6.5-3-7).
For Lawrenceburg Distillers Indiana, LLC, formerly Joseph E.
Seagram and Sons, Inc. (326 IAC 6.5-3-8) in Dearborn County, the
reference to Boiler 5 has been removed, because it is no longer
operating. The remaining emission limits for this facility were not
changed.
c. Dubois County
There were seven facilities listed in the previously approved SIP
for Dubois County whose entries have been removed from 326 IAC 6.5-4,
due to company shutdowns or the removal of all PM10-emitting units. The
seven facilities are: Hoosier Desk (326 IAC 6.5-4-7); Indiana Furniture
Industries (326 IAC 6.5-4-11); Jasper Cabinet No. 1 (326 IAC 6.5-4-12);
Jasper Cabinet No. 2 (326 IAC 6.5-4-13); Jasper Cabinets Corporation
(326 IAC 6.5-4-14); Jasper Veneer (326 IAC 6.5-4-22); and Jasper Wood
Products (326 IAC 6.5-4-23).
The numerical PM10 emission limits for ten facilities in Dubois
County are unchanged from the previously approved SIP. Their entries in
326 IAC 6.5-4 were only edited for format consistency or name changes.
The ten facilities are: Kimball Office--Jasper 15th Street, formerly
Artec (326 IAC 6.5-4-2); DMI Furniture Plant No. 5, formerly Dolly
Madison Plant No. 5 (326 IAC 6.5-4-4); Dubois County Farm Bureau Co-op
(326 IAC 6.5-4-5); Forest Products No. 1 (326 IAC 6.5-4-6); Indiana
Desk Company (326 IAC 6.5-4-9); Jasper Desk Company, Incorporated (326
IAC 6.5-4-16); Kimball Office--Jasper Cherry Street, formerly Jasper
Laminates, Plant 1--Division of Kimball (326 IAC 6.5-4-17);
Jasper Municipal Electric Utility (326 IAC 6.5-4-18); Jasper Seating
(326 IAC 6.5-4-21); and Styline Industries, Inc. Plant 8 (326
IAC 6.5-4-24).
The revised rule does not change the previous PM10 emission limits
for Indiana Dimension, Indiana Furniture Industries, formerly Indiana
Dimension (326 IAC 6.5-4-10). However, the revised rule adds a wood
working-dust collector emission limit of 0.4 tons per year. This
emission unit was previously listed in the Indiana PM10 SIP at 326 IAC
6.5-4-8, in the entry for Indiana Chair. The Indiana Chair facility has
not moved, but it is now part of Indiana Dimension, Indiana Furniture
Industries, and its PM10 emission limits have been added to 326 IAC
6.5-4-10. The listing at 326 IAC 6.5-4-8 for Indiana Chair has been
removed from the SIP.
The revised rule does not change the previous PM10 emission limits
for JOFCO Inc. Plants 1 and 2, formerly Jasper Office Furniture Co.,
Inc., Plant 1 (326 IAC 6.5-4-19) in Dubois County. However,
the revised rule adds an emission limit of 1.2 tons per year for wood
working. This PM10 emission source and emission limit were previously
listed in the Indiana PM10 SIP at 326 IAC 6.5-4-20, in a separate entry
for Jasper Office Furniture. The Jasper Office Furniture facility has
not moved, but it is now part of JOFCO, Inc., and its PM10 emission
limits have been added to 326 IAC 6.5-4-19. The listing at 326 IAC 6.5-
4-20 for Jasper Office Furniture has been removed from the SIP.
For Jasper Seating Co., Inc., Plant No. 3, formerly Dolly Madison
Plant No. 4 (326 IAC 6.5-4-3), the rating for the wood-fired boiler has
been corrected from 5 MMBtu/hr to 10.5 MMBtu/hr. The emission limits of
9.4 tpy and 0.60 lbs/MMBtu have not changed.
For Jasper Chair Company, Inc. (326 IAC 6.5-4-15), the rating for
the wood boiler has been corrected from 18 MMBtu/hr to 18.3 MMBtu/hr.
The annual emission limit for that boiler increased from 15.6 tpy to
15.77 tpy, while the short-term limit of 0.60 lb/MMBtu remained the
same. The emission limit for wood working operations at this facility
is unchanged.
Indiana performed dispersion modeling to show that the emission
increases at Jasper Seating Co., Inc. and Jasper Chair Company, Inc.
would be protective of the PM10 NAAQS. See Section V for a discussion
of the State's modeling analysis.
d. Howard County
There were nine facilities listed in the previously approved SIP
for Howard County whose entries have been removed from 326 IAC 6.5-5,
due to company shutdowns or the removal of all PM10 emitting units. The
nine facilities are: Cuneo Press (326 IAC 6.5-5-3); Greentown Grain
(326 IAC 6.5-5-6); Howard Co. Farm Bureau Co-op (Greentown) (326 IAC
6.5-5-7); Howard Co. Farm Bureau Co-op (Russiaville) (326 IAC 6.5-5-8);
Judson Feed & Grain (326 IAC 6.5-5-9); Name, Inc. (326 IAC 6.5-5-12);
Penn-Dixie; boilers (326 IAC 6.5-5-13); Penn-Dixie; furnaces (326 IAC
6.5-5-14), and Russiaville Feed & Grain (326 IAC 6.5-5-15).
The numerical PM10 emission limits for three facilities in Howard
County are unchanged from the previously approved SIP. Their entries in
326 IAC 6.5-5 were only edited for format consistency or name changes.
The three facilities are: Kokomo Grain Company (326 IAC 6.5-5-10); E &
B Paving, Inc., formerly Mohr Construction (326 IAC 6.5-5-11); and
Martin Marietta Materials, Inc., formerly Yeomen Stone & Sand (326 IAC
6.5-5-16).
The new rule removes the entry for two gas-fired boilers, Stack 2,
at Delco Electronics Corporation, formerly Delphi Delco (326 IAC 6.5-5-
5). The boilers are no longer operating. The remainder of 326 IAC 6.5-
5-5 is unchanged.
For Chrysler, LLC-Kokomo Casting Plant and Kokomo Transmission
Plant, formerly Chrysler-Haynes (326 IAC 6.5-5-2) in Howard County, the
entries for Reverberatory Furnaces D and E, both 92.5 tons per year,
and Gas Boiler 3, have been removed, because the units are no longer
operating. The revised rule adds a listing for Boiler 5, restricted to
natural gas only, and an emission limit of .75 lb/MMBtu for Boiler 4 at
the Chrysler, LLC-Kokomo Transmission Plant. Boiler 4 burns reclaimed
residual oil or natural gas. Boilers 4 and 5 were previously listed in
the Indiana PM10 SIP at 326 IAC 6.5-5-4, in a separate entry for
DaimlerChrysler-U.S. 31. The two boilers, along with Boilers 1, 2, and
[[Page 13816]]
3 at the same facility, each had emission limits of 0.75 lb/MMBtu and
shared an overall limit of 875.7 tpy in 326 IAC 6.5-5-4. The
DaimlerChrysler-U.S. 31 facility, now known as the Chrysler, LLC-Kokomo
Transmission Plant, has not moved, but its PM10 emission limits have
been included in 326 IAC 6.5-5-2. Boilers 1, 2, and 3 have been shut
down and demolished. Boiler 4 retains its original limit of 0.75 lb/
MMBtu with no tons-per-year limit. The listing at 326 IAC 6.5-5-4 for
DaimlerChrysler-U.S. 31 has been removed from the SIP.
e. Marion County
The revised rule no longer contains 6.5-6-1(b), which provided that
``sources shall be considered in compliance with the tons per year
emission limits established in sections 2 through 36 of this rule if
within five percent (5%) of the emission limit.'' The removal of this
provision strengthens the SIP.
There were twenty-one facilities listed in the previously approved
SIP for Marion County whose entries have been removed from 326 IAC 6.5-
6, due to company shutdowns or the removal of all PM10-emitting units.
The 21 facilities are: Bridgeport Brass (326 IAC 6.5-6-4); Central
State Hospital (326 IAC 6.5-6-6); Chevrolet (326 IAC 6.5-6-7); Chrysler
(El.) Shade (326 IAC 6.5-6-8); Chrys. Fdy S. Tibbs (326 IAC 6.5-6-9);
Community Hospital (326 IAC 6.5-6-10); Design Mix (326 IAC 6.5-6-11);
Farm Bureau (Fert.) (326 IAC 6.5-6-12); FMC Bearing (326 IAC 6.5-6-13);
FMC Chain (326 IAC 6.5-6-14); Fort Benjamin Harrison (326 IAC 6.5-6-
16); Glass Containers (326 IAC 6.5-6-17); Indep. Concrete Pipe (326 IAC
6.5-6-19); Indpls. Rubber Co. (326 IAC 6.5-6-20); Ind. Asph. Pav. Co.
(326 IAC 6.5-6-21); Nat'l R.R. (Amtrak) (326 IAC 6.5-6-24); Praxair
(326 IAC 6.5-6-27); RCA (326 IAC 6.5-6-29); Refined Metals (326 IAC
6.5-6-30); Richardson Co. (326 IAC 6.5-6-32); and Stokely Van Camp (326
IAC 6.5-6-36).
The numerical PM10 emission limits for seven facilities in Marion
County are unchanged from the previously approved SIP. Their entries in
326 IAC 6.5-6 were only edited for format consistency or name changes.
The seven facilities are Allison Transmission (326 IAC 6.5-6-2); Bunge
North America (East), Inc., formerly Central Soya (326 IAC 6.5-6-5);
Indiana Veneers Corporation (326 IAC 6.5-6-22); Quemetco, Inc. (RSR
Corporation) (326 IAC 6.5-6-28); Rolls-Royce Corporation (326 IAC 6.5-
6-33); St. Vincent's Hospital and Health Care Service, formerly St.
Vincent's Hospital (326 IAC 6.5-6-34), and Belmont Waste Water Sludge
Incinerator, formerly Sludge Incinerator (326 IAC 6.5-6-35).
The entry for Asphalt Materials, Inc., formerly Asph. Mat. &
Const., Inc. (326 IAC 6.5-6-3), has been updated. The PM10 emission
limits formerly listed for the Oxid. Tank are now listed for the
Asphalt Blowing Stills. The numerical limits have not changed.
The PM10 emission limits for Citizens Thermal Energy C.C. Perry K,
formerly IPL (326 IAC 6.5-6-23), have not changed. A new rule section,
326 IAC 6.5-6-23.1, has been added for Indianapolis Power and Light
Company (IPL) Harding Street Station. This facility was formerly known
as IPL Stout. The emission limits for IPL Stout were previously
included with the limits for IPL Perry K, now known as Citizens Thermal
Energy C.C. Perry K (326 IAC 6.5-6-23). The PM10 SIP emission limits
for Indianapolis Power and Light Company (IPL) Harding Street Station,
formerly IPL Stout, have not changed.
The new rule removes individual unit emission limits for three
facilities in Marion County. For Automotive Components Holdings, LLC-
Indianapolis Plant, formerly Ford Motor Co. (326 IAC 6.5-6-15), the
entry for Boiler 1 was removed. This unit is no longer operating. For
Cargill, Inc., formerly Cargill Dry Corn Ingredients, Inc., formerly
Illinois Cereal Mills, Incorporated, (326 IAC 6.5-6-18), ten emission
units have been removed from the rule, due to process shutdowns. No
other emission limits at the facility have changed. For National Starch
and Chemical Company, formerly National Starch (326 IAC 6.5-6-25), the
entry for Boiler 4 has been removed, because the boiler is no longer
operating. No other PM10 emission limits at the facility have changed.
For International Truck and Engine Corporation & Indianapolis
Casting Corporation, formerly Navistar International, (326 IAC 6.5-6-
26), the entry for the Phase 3 Baghouse has been clarified to apply to
the Phase 3 North and South Baghouses. Indiana stated that the
baghouses vent through three stacks of the same height, very near each
other. The emission limit, which applies to the baghouses as a whole,
has not changed. This change is not expected to impact the PM10
concentrations in the vicinity of the facility. See Section V for a
discussion of the State's analysis.
For Vertellus Agriculture and Nutrition Specialties, LLC
(Vertellus), formerly Reilly Industries, Inc. (326 IAC 6.5-6-31),
Indiana has stated that the correct PM10 emission limits for the 186N
and 2724W units were mistakenly removed during a previous rule revision
(approved by EPA at 69 FR 5036, February 3, 2004). The limits for the
2724W unit are reinstated in the revised rule at 4.0 tpy and 0.15 lb/
MMBtu. The revised rule combines the reinstated annual limit for the
186N unit (0.9 tpy) with the unchanged annual limits for the 2722W and
2726S units (3.5 and 7.8 tpy, respectively) into one 12.2 tpy shared
limit. This shared limit is equivalent to the sum of the three sources'
previous individual tons per year limits. With this change, the 186N
unit increases its fuel limit slightly, from 0.011 lb/MMBtu to 0.15 lb/
MMBtu. The fuel limits for the other two sources are unchanged.
Also in the revised rule for Vertellus, Unit 722804 is no longer
restricted to only burning natural gas, but its limits of 0.2 tpy and
0.011 lb/MMBtu are not changed. The emission limits for Unit 732714
have been decreased from 7.5 tpy to 2.7 tpy and from 0.15 lb/MMBtu to
0.011 lb/MMBtu. In addition, the 112E boiler, listed in previous
versions of the PM10 SIP at 0.5 tpy and 0.15 lb/MMBtu, is no longer
listed in 326 IAC 6.5-6-31. It is a waste heat boiler which performs no
combustion and has no PM10 emissions of its own. Indiana performed
dispersion modeling to show that the revised emission limits at
Vertellus would lead to lower impacts on air quality compared to the
previous emission limits. See Section V for a discussion of the State's
modeling analysis.
f. St. Joseph County
There were twelve facilities listed in the previously approved SIP
for St. Joseph County whose entries have been removed from 326 IAC 6.5-
7, due to company shutdowns or the removal of all PM10 emitting units.
The twelve facilities are: Allied Signal Aerospace (326 IAC 6.5-7-2);
AM General (326 IAC 6.5-7-3); ARCO Engg. Const. Corporation (326 IAC
6.5-7-4); Asphalt Engineers (326 IAC 6.5-7-5); I & M-Twin Branch (326
IAC 6.5-7-7); Mishawaka Brass (326 IAC 6.5-7-8); Northern Indiana
Children's Hospital (326 IAC 6.5-7-9); Reliance Electric-Dodge (326 IAC
6.5-7-12); Uniroyal (326 IAC 6.5-7-15); Volney Felt Mills (326 IAC 6.5-
7-17); Wheelabrator Frye (326 IAC 6.5-7-19), and White Farm Equipment
Company (326 IAC 6.5-7-20).
The numerical PM10 emission limits for three facilities in St.
Joseph County are unchanged from the previously approved SIP. Their
entries in 326 IAC 6.5-7 were only edited for format consistency or
name changes. The three facilities are: Bosch Braking Systems
Corporation (326 IAC 6.5-7-6); Holy
[[Page 13817]]
Cross Services Corporation (Saint Mary's Campus) (326 IAC 6.5-7-13,
with recent revisions approved by EPA on July 30, 2007, at 72 FR
41450); and the University of Notre Dame du Lac (326 IAC 6.5-7-16).
The new rule removes individual unit emission limits for two
facilities in St. Joseph County. For RACO-Hubbell Electric Products,
formerly RACO (326 IAC 6.5-7-10), the entry for oil-fired boiler nos. 1
and 2 have been removed. These boilers no longer operate. The remaining
PM10 emission limits for this facility are unchanged. For Accucast
Technology, LLC, formerly Sibley Machine & Foundry (326 IAC 6.5-7-14),
the entries for the Cupola and the Tumble Blast have been removed.
These units are no longer operating. The remaining PM10 emission limits
have not changed. In the final revised rule, Accucast's PM10 emission
limits were inadvertently given with units of pounds per million
British Thermal Units, which is incorrect. The emission limits should
be in grains per dry standard cubic foot. A correction notice was
published in the Indiana Register on February 5, 2008, to correct this
error.
For Reith Riley Construction Company, Inc. (326 IAC 6.5-7-11), one
Rotary Dryer with limits of 11.10 tpy is no longer operating and has
been removed from the rule. The other unit, a Rotary Dryer with limits
of 1.70 tpy and 0.052 gr/dscf, has been replaced by a Drum Mixer/
Burner, with limits of 78.5 tpy and 0.03 gr/dscf. The PM10 limits for
the Rotary Dryer at Walsh & Kelly, Inc. (326 IAC 6.5-7-18) have been
increased from 20.48 tpy to 53.22 tpy. Indiana performed dispersion
modeling to show that these emission limit increases would be
protective of the PM10 NAAQS. See Section V for a discussion of the
State's modeling analysis.
g. Vanderburgh County
The revised rule no longer contains 6.5-8-1(b), which provided that
``compliance with the tons per year limit shall be acceptable if within
five percent (5%) of the established tons per year emission limit.''
The removal of this provision strengthens the SIP.
There were ten facilities listed in the previously approved SIP for
Vanderburgh County whose entries have been removed from 326 IAC 6.5-8,
due to company shutdowns or the removal of all PM10-emitting units. The
ten facilities are: Bernadin (326 IAC 6.5-8-2); Craddock Finishing (326
IAC 6.5-8-3); Evv. State Hospital (326 IAC 6.5-8-4); Evansville Veneer
and Lumber (326 IAC 6.5-8-5); General Foods (326 IAC 6.5-8-6); Inland
Container (326 IAC 6.5-8-7); International Steel (326 IAC 6.5-8-8);
Mead Johnson (326 IAC 6.5-8-9); National of Evansville (326 IAC 6.5-8-
10); and Whirlpool--Morgan Avenue (326 IAC 6.5-8-15).
The numerical PM10 emission limits for two facilities in
Vanderburgh County are unchanged from the previously approved SIP.
Their entries in 326 IAC 6.5-8 were only edited for format consistency
or name changes. The two facilities are: Land O'Lakes Purina Feed LLC,
formerly Purina Mills, Inc. (326 IAC 6.5-8-12) and Southern Indiana Gas
and Electric Company, Broadway Avenue Generating Station, formerly
SIGECO (326 IAC 6.5-8-13).
The new rule reduces or removes individual unit emission limits for
two facilities in Vanderburgh County. For Nunn Milling Company, Inc.
(326 IAC 6.5-8-11), the entries and emission limits for seven units
have been removed due to process shutdowns. Only the hammer mill
remains in the SIP rule, with unchanged PM10 emission limits. For
Whirlpool Corporation Highway 41 North (326 IAC 6.5-8-14), boiler no.
2, formerly coal-fired, is now required to use natural gas only, and
the PM10 emission limits for boiler no. 2 have been removed from the
rule. This is consistent with Indiana's practice for other units in
Indiana's previous natural gas rule, approved by EPA on February 3,
2004, at 69 FR 5036. Boiler no. 3, formerly coal-fired, and boiler no.
5, formerly oil-fired, are now each limited to natural gas with
2 fuel oil backup. Their PM10 emission limits are unchanged
from the previous SIP. The entry for boiler no. 4 has been removed, as
this unit is no longer operating.
h. Vigo County
The revised rule no longer contains 6.5-9-1(b), which provided that
``compliance with the tons per year limit shall be acceptable if within
five percent (5%) of the established tons per year emission limit.''
The removal of this provision strengthens the SIP.
There were twelve facilities listed in the previously approved SIP
for Vigo County whose entries have been removed from 326 IAC 6.5-9, due
to company shutdowns or the removal of all PM10 emitting units. The
twelve facilities are: Alcan (326 IAC 6.5-9-2); Columbian Home Products
(326 IAC 6.5-9-3); Gartland Foundry (326 IAC 6.5-9-4); Indiana Gas and
Chemical (326 IAC 6.5-9-6); ISU (326 IAC 6.5-9-7); J.I. Case (326 IAC
6.5-9-9); Rose Hulman (326 IAC 6.5-9-12); Terre Haute Concrete (326 IAC
6.5-9-14); Terre Haute Malleable (326 IAC 6.5-9-16); United States
Penitentiary (326 IAC 6.5-9-18); Wabash Fibre Box (326 IAC 6.5-9-19);
and Wabash Valley Asphalt (326 IAC 6.5-9-20).
The numerical PM10 emission limits for two facilities in Vigo
County are unchanged from the previously approved SIP. Their entries in
326 IAC 6.5-9 were only edited for format consistency or name changes.
The two facilities are S&G Excavating, Inc., formerly Martin Marietta
(326 IAC 6.5-9-10) and Ulrich Chemical, Inc. (326 IAC 6.5-9-17).
The new rule for Terre Haute Grain (326 IAC 6.5-9-15) in Vigo
County does not change any PM10 emission limits. However, the revised
rule adds a 1.7 tpy limit for drying and a 16.0 tpy limit for handling.
These emission units were previously listed in the Indiana PM10 SIP at
326 IAC 6.5-9-5, in the entry for Graham Grain. The Graham Grain
facility has not moved or changed, but its PM10 emission limits have
been included in 326 IAC 6.5-9-15. The separate listing at 326 IAC 6.5-
9-5 for Graham Grain has been removed from the SIP.
The new rule reduces or removes individual unit emission limits for
two facilities in Vigo County. For International Paper Company (326 IAC
6.5-9-8), the entry for the no. 5 boiler has been removed, because the
boiler is no longer operating. The PM10 limits for the remaining units
at this facility are unchanged. For Sisters of Providence (326 IAC 6.5-
9-13), the no. 2 and 3 boilers are limited to natural gas with fuel oil
backup. The tons-per-year limit for these boilers has been removed, but
the 20.52 pounds-per-hour (lb/hr) limit for these boilers, which was
equivalent to the former tons-per-year limit, has been retained. A
limit of 0.341 lb/MMBtu has been added for the no. 2 and 3 boilers. The
entry for the nos. 5, 7, and 8 boilers has been removed. These units
are no longer operating.
The PM10 emission limits for Duke Energy Indiana, Inc.--Wabash
River Generating Station, formerly PSI (326 IAC 6.5-9-11), have not
changed, but the limits apply to fewer units than previously. The
limits used to cover Units 1-6, but in the revised rule, the same
limits cover only Units 2-6. Unit 1 has not operated since 1994.
Indiana has stated that while the current annual emission limit, 4102.3
tpy, was based upon six operating units and should be revised in a
future rulemaking, the total maximum possible emissions from the five
remaining units, at their full 0.1338 lb/MMBtu emission limits, would
be 4017 tpy. Therefore, removing the reference to Unit 1 does not
result in an increase in allowable PM10 emissions.
[[Page 13818]]
i. Wayne County
There were six facilities listed in the previously approved SIP for
Wayne County whose entries have been removed from 326 IAC 6.5-10, due
to company shutdowns or the removal of all PM10 emitting units. The six
facilities are: Dana Perfect Circle Richmond (326 IAC 6.5-10-7); Design
& Manufacturing (326 IAC 6.5-10-8); Farmer's Grain (326 IAC 6.5-10-10);
Schrock Cabinet Company (326 IAC 6.5-10-17); Wallace Metals (326 IAC
6.5-10-18); and Wayne County Farm Bureau (326 IAC 6.5-10-19).
The numerical PM10 emission limits for seven facilities in Wayne
County are unchanged from the previously approved SIP. Their entries in
326 IAC 6.5-10 were only edited for format consistency or name changes.
The seven facilities are: Barrett Paving Materials, Inc. (326 IAC 6.5-
10-2); Autocar LLC, formerly Dana Perfect Circle-Hagerstown (326 IAC
6.5-10-6); Earlham College (326 IAC 6.5-10-9); Joseph H. Hill Co. (326
IAC 6.5-10-12); Land O'Lakes Purina Feed LLC, formerly Purina Mills,
Inc. (326 IAC 6.5-10-13); Richmond Power & Light--Whitewater Valley
Generating Station (326 IAC 6.5-10-15); and Richmond State Hospital
(326 IAC 6.5-10-16).
The new rule reduces or removes individual unit emission limits for
four facilities in Wayne County. Previously, there were two rules for
Belden Wire and Cable Company, 326 IAC 6.5-10-3 (office) and 326 IAC
6.5-10-4 (plant). The revised PM10 SIP gives a single entry for Belden
Wire and Cable Company at 326 IAC 6.5-10-3. There is no longer a rule
listing numbered 326 IAC 6.5-10-4. The revised rule for Belden Wire and
Cable Company retains the emission limits for the plastic compounding,
rubber mixing, and pneumatic processes from the former rule 326 IAC
6.5-10-4. The entry and emission limits for the oil boiler, originally
in 326 IAC 6.5-10-3, have been removed, because the boiler is no longer
operating. For Milestone Contractors LP (Cambridge City), formerly
Cambridge City Milestone Contractors (326 IAC 6.5-10-5), the previous
listing for the rotary dryer now applies to the drum dryer. The dryer's
emission limits have decreased from 67.4 tpy to 45.74 tpy and from
0.218 grains per dry standard cubic foot (gr/dscf) to 0.04 gr/dscf. For
Johns Manville International, Inc., formerly Johns Manville Corporation
(326 IAC 6.5-10-11), two units are limited by the revised rule to burn
natural gas only, and their numerical emission limits have been removed
from the SIP. This is consistent with Indiana's practice for other
natural gas units. Four other units and their emission limits have been
entirely removed from the rule. These units are no longer operating.
The PM10 emission limits for the remaining two units in the SIP, line 2
and line 3 forming and collection, have not changed. For Milestone
Contractors Richmond, formerly Richmond Milestone Contractors (326 IAC
6.5-10-14), the listing for the rotary dryer now applies to the counter
flow drum mixer, and the emission limits have been reduced from 50.80
tpy to 46.76 tpy, and from 0.158 gr/dscf to 0.04 gr/dscf.
IV. What Has Indiana Revised in 326 IAC 6.8?
326 IAC 6.8 covers PM10 emissions at facilities in Lake County.
Rule 326 IAC 6.8-1, General Provisions, has been updated to match the
current rule structure of 326 IAC 6.8. Rule 326 IAC 6.8-2 contains
updated and revised facility-specific PM10 emission limits. The former
rule 326 IAC 6.8-3, Lake County: Opacity Limits; Exceptions to 326 IAC
5-1-2, has been repealed. Its provisions have been placed in the
appropriate facility-specific sections of 326 IAC 6.8-2. There were
minor editorial changes to Rule 326 IAC 6.8-4, Lake County: Opacity
Limits; Test Methods.
The former rule 326 IAC 6.8-5-1, Lake County: Opacity Continuous
Emissions Monitors, has been repealed. Its provisions have been placed
in 326 IAC 6.8-2-1(e), and in the appropriate facility-specific
sections of 326 IAC 6.8-2. The former rule 326 IAC 6.8-6, Lake County:
Combustion Sources; Natural Gas, has been repealed. The sources named
in the former sections 326 IAC 6.8-6-2 through 326 IAC 6.8-6-20, have
been limited in the facility-specific sections of the revised rule 326
IAC 6.8-2 to natural gas combustion only, without numerical PM10
emission limits.
The former rule 326 IAC 6.8-7, Lake County: Site-Specific Control
Requirements, has been repealed, because most of its provisions were
outdated, referring to scheduled control device installations or
industrial unit shutdowns which have already occurred. The provisions
which still apply to Lake County sources have been added to the
appropriate facility-specific sections of 326 IAC 6.8-2. Rule 326 IAC
6.8-8-1, Lake County: Continuous Compliance Plan, has been updated to
reflect the current list of applicable facilities.
The remainder of 326 IAC 6.8-8 is unchanged. For Rule 326 IAC 6.8-
9, Lake County: PM10 Coke Battery Emission Requirements, sections 6.8-
9-1 and 6.8-9-2 are unchanged. Section 6.8-9-3 has been amended to
remove a reference to Inland Steel (now known as Mittal Steel--Indiana
Harbor East Inc.). The requirements referring to this facility have
been incorporated into the facility's entry at 326 IAC 6.8-2-17. Rule
326 IAC 6.8-10-1, Lake County: Fugitive Particulate Matter, has been
updated to reflect the current list of applicable facilities. The
remainder of 326 IAC 6.8-10 is unchanged. Rule 326 IAC 6.8-11, Lake
County: Particulate Matter Contingency Measures, is unchanged.
Regarding the changes to 326 IAC 6.8-2, there were six facilities
listed in the previously approved SIP for Lake County that have been
removed from 326 IAC 6.8-2, due to company shutdowns or the removal of
all PM10-emitting units previously regulated under the PM10 SIP. The
six facilities are: American Steel Foundries--East Chicago (326 IAC
6.8-2-3); Associated Box (326 IAC 6.8-2-5); General Refractory (326 IAC
6.8-2-10); SCA Tissue North America LLC, formerly Georgia Pacific (326
IAC 6.8-2-11); Globe Industries (326 IAC 6.8-2-12); and Marport
Smelting (326 IAC 6.8-2-23).
The numerical PM10 emission limits for fifteen facilities in Lake
County are unchanged from the previously approved SIP. Their entries in
326 IAC 6.8-2 were only edited for format consistency or name changes.
The fifteen facilities are: Bucko Construction Company, Inc. (326 IAC
6.8-2-7); W.R. Grace and Co.--Conn., formerly E. I. Dupont (326 IAC
6.8-2-9); Hammond Group, Inc.--Halstab Division (326 IAC 6.8-2-14);
Jupiter Aluminum Corporation (326 IAC 6.8-2-18); Carmeuse Lime Inc.,
formerly Marblehead Lime Company (326 IAC 6.8-2-22); Methodist Hospital
Inc. (326 IAC 6.8-2-24); National Recovery Systems (326 IAC 6.8-2-25);
NIPSCo--Dean H. Mitchell Station (326 IAC 6.8-2-26); Premiere Candy
Company (326 IAC 6.8-2-28); Reed Minerals--Plant 14 (326 IAC
6.8-2-29); Rhodia, Inc. (326 IAC 6.8-2-30); Smith Ready Mix, Inc. (326
IAC 6.8-2-32); State Line Energy, LLC (326 IAC 6.8-2-33); Huhtamaki
Foodservice, Inc., formerly The Chinet Company (326 IAC 6.8-2-34); and
Union Tank Car Company, Plant 1 (326 IAC 6.8-2-36).
The PM10 emission limits for U.S. Steel--Gary Works (326 IAC 6.8-2-
38) have not changed. The opacity limits for U.S. Steel--Gary Works in
326 IAC 6.8 are also unchanged, but they have been relocated to 326 IAC
6.8-2-38(b). These facility-specific opacity limits take
[[Page 13819]]
precedence over the limits in Indiana's opacity regulations at 326 IAC
5-1-2.
For Silgan Containers Manufacturing Corporation (326 IAC 6.8-2-31),
the previous PM10 SIP contained an emission limit for a stack serving
three incinerator units. The listing in 326 IAC 6.8-2-31 for that stack
has been revised to apply to ``Two (2) stacks serving an incinerator (1
unit),'' with the previous PM10 emission limits of 0.007 lbs/MMBTU and
0.310 lbs/hr unchanged. However, according to IDEM, the company's
October 2007 State-issued operating permit indicates that the single
incinerator now vents to only one stack. The other PM10 emission limits
for this facility are unchanged.
The new rule removes individual unit emission limits for eight
facilities in Lake County. For Cargill, Inc., formerly Cerestar USA,
Inc. (326 IAC 6.8-2-8), twenty-six PM10 emission limits have been
removed, due to process shutdowns. The other PM10 emission limits for
this facility are unchanged.
The limits for Hammond Group, Inc. (HGI)--Expander Division,
formerly at 326 IAC 6.8-2-15, have been combined with that of Hammond
Group, Inc. (HGI)--Halox Division, formerly at 326 IAC 6.8-2-13,
resulting in the revised rule 326 IAC 6.8-2-13, now titled Hammond
Group, Inc. (HGI) Halox Division, Lead Products Division, and Hammond
Expander Division. The entry for the Expander Division Stack 1-S-54 has
been removed because PM10 is no longer emitted from that stack. The
other PM10 emission limits for the Halox Division and Expander Division
of this facility are unchanged. The listing numbered 326 IAC 6.8-2-15
has been removed from the SIP.
For Mittal Steel--Indiana Harbor East Inc., formerly Inland Steel
(326 IAC 6.8-2-17), previously listed PM10 emission limits have been
removed for 15 units which are no longer operating. The PM10 emission
limits for Blending system baghouse B have also been removed, because
the baghouse was never constructed. The other PM10 emission limits for
this facility are unchanged. The opacity limits for this facility in
326 IAC 6.8 are not changed, but they have been relocated to 326 IAC
6.8-2-17(b). These facility-specific opacity limits take precedence
over the limits in Indiana's opacity regulations at 326 IAC 5-1-2.
For Dover Chemical Corporation--Hammond, formerly Keil Chemical--
Division of Ferro Corporation (326 IAC 6.8-2-19), the PM10 emission
limits for Pyro-chek 68PB1 of 0.052 lbs/ton and 0.030 lbs/hr and the
PM10 limits for Pyro-chek 77PB2 of 0.122 lbs/ton and 0.040 lbs/hr have
been removed because the units are no longer operating. The other PM10
emission limits for this facility are unchanged.
For Mittal Steel--Indiana Harbor West Inc., formerly LTV Steel
Corporation (326 IAC 6.8-2-21), the PM10 limits for Utility Boiler
number 3 and Utility boiler number 4 have been removed because the
boilers are no longer operating. The previous PM10 limits were 0.066
lbs/MMBTU and 12.85 lbs/hr for each boiler. The other PM10 emission
limits for this facility are unchanged. The opacity limits for this
facility in 326 IAC 6.8 are not changed, but they have been relocated
to 326 IAC 6.8-2-21(b). These facility-specific opacity limits take
precedence over the limits in Indiana's opacity regulations at 326 IAC
5-1-2.
For Praxair Inc. (326 IAC 6.8-2-27), the PM10 emission limits of
42.5 lbs/ton and 0.340 lbs/hr for the cylinder paint spray booth, stack
033; the limits of 42.5 lbs/ton and 0.340 lbs/hr for the drum paint
spray booth, stack 073; and the limits of 0.004 gr/dscf and 0.042 lbs/
hr for the cylinder shotblaster number 2 baghouse, stack 030, have all
been removed because the units are no longer operating. The other PM10
emission limits for this facility are unchanged.
For Conopco, Inc. d/b/a Unilever HPC USA, formerly listed as
Unilever HPC USA (326 IAC 6.8-2-35), sixteen emission units have been
removed from the rule because they are no longer operating. These
removals lower the facility's total allowable PM10 emissions by
approximately 25 pounds per hour. The other PM10 emission limits for
this facility are unchanged.
For the United States Gypsum Company (326 IAC 6.8-2-37), the PM10
emission limits for the following have been removed, due to process
shutdowns, for a total reduction of about 1.38 lb/hr: rail car
unloading, stack J10; the Franklin fiber process, stack M6; wallboard
end sawing, Stack B2; and the panel saw process. The other PM10
emission limits for this facility are unchanged.
At BP Products North America, Inc.--Whiting Refinery (BP) (326 IAC
6.8-2-6), many emission units currently burn natural gas or refinery
gas. Several sources at BP were previously allowed to burn fuel oil,
but are now limited to natural gas or refinery gas under the revised
rule. In this rule, all gas-burning units are given revised emission
limits that reflect the most current EPA PM10 emission factor for gas
combustion provided in AP-42. Refinery gas is considered to have
similar PM10 emissions to natural gas. The emission limits, 0.0075 lb/
MMBtu, are higher than the previous gas combustion emission limits,
which were 0.004 lb/MMBtu. The previous emission limits were also based
on EPA emission factors, but they only included filterable PM10, which
is emitted directly from the stacks as solid or liquid particulate
matter. The newer factor includes both filterable PM10 and condensable
PM10, which is emitted from the stacks as hot gases or vapor, and which
later cools and condenses into aerosol droplets, also treated as PM10.
The emission test methods for compliance determinations at BP are
revised to require the measurement of both filterable and condensable
particulate. The new limit better quantifies the total PM10 emitted
from natural gas combustion.
Emission limits are also given in pounds per hour for most sources
at BP; these are adjusted to account for the revised gas combustion
emission estimates. Although the numerical limits have increased, the
actual PM10 emissions at the gas combusting sources are not expected to
change, because the units will still be using the same fuel as before.
Actual PM10 emissions will decrease at those sources which were
previously allowed to burn fuel oil but are now using only natural gas
and refinery gas. Eleven units which have been shut down were removed
from the rule. Overall, the allowable PM10 emissions at BP decrease by
477 tpy under the revised rule.
ASF--Keystone, Inc.--Hammond (ASF--Keystone), formerly American
Steel Foundry--Hammond (326 IAC 6.8-2-4), no longer operates Tub
Grinder number 3-0388, and its limits are removed from 326 IAC 6.8-2-4.
Several spring grinder units at ASF--Keystone now vent to a control
device with a single stack; therefore, their emission limits have been
combined into a single emission limit for the stack.
For Resco Products, Inc., formerly Harbison Walker Refractories,
Hammond Works (326 IAC 6.8-2-16), an emission limit of 0.0330 lb/ton
and 0.460 lb/hr originally applied to two mixers venting to one stack
(D-5). The two mixers now vent to separate stacks (D-5 and D-14), so
the original limit was split into two separate limits of 0.0165 lb/ton
and 0.230 lb/hr. The newly added limit for Resin-bonded materials
handling, batching and pressing at Stack D-12A represents a combination
of the former emission limits for the magnesite auxiliary milling
system (Stack D-14), the magnesite smooth roll crusher system (D-15),
and the specialty magnesite handling system (D-16). The new limit,
which equals the sum of the three former limits, is 0.25 lb/ton and
0.93 lb/hr. The previous entry for Chrome
[[Page 13820]]
Ore screening and milling, Stack D-12, with limits of 0.078 lb/ton and
1.24 lb/hr, has been removed from 326 IAC 6.8-2-16, because the process
has been shut down. Overall, these changes represent an emissions
decrease of 1.24 lb/hr.
LaSalle Steel Company (LaSalle Steel) (326 IAC 6.8-2-20) petitioned
Indiana for higher emission limits on its shot blasting operation.
LaSalle Steel was unable to comply with its PM10 SIP limits using its
control device, a baghouse, installed in 1992. According to Indiana,
the original 0.02 lb/hr emission limit should have been 0.02 grains per
actual cubic foot (based on the baghouse manufacturer's guarantee).
That rate corresponds to 2.57 lb/hr and 0.086 pounds per ton. Indiana
revised LaSalle's shot blasting limits from 0.02 lb/hr to 2.57 lb/hr
and 0.001 lb/ton to 0.086 lb/ton, which is more consistent with the
equipment guarantee.
Indiana performed dispersion modeling to show that the emission
limit changes at BP, ASF Keystone, Resco, and LaSalle Steel would still
be protective of the PM10 NAAQS. See Section V for a discussion of the
State's modeling analysis.
V. PM10 Modeling Analyses
To demonstrate that any increases in PM10 emission limits within
326 IAC 6.5 and 326 IAC 6.8 would still be protective of the PM10
NAAQS, Indiana performed dispersion modeling. Indiana used the AERMOD
regulatory dispersion model, version 07026, to evaluate the impacts of
the increased PM10 limits in the revised rules. Five years of
representative local surface and upper air National Weather Service
data were used in each AERMOD analysis. Indiana used the AERMET
meteorological data processor, version 06341, a part of the AERMOD
modeling system, to prepare the surface meteorological data and
vertical profiles, using the seasonal surface characteristics at each
surface meteorological data site. Indiana used the Building Profile
Input Program (BPIP), version 04274, to prepare wind direction-specific
building dimension data for each source. This program also calculates
downwash inputs for the Plume Rise Model Enhancements (PRIME) algorithm
in AERMOD. Receptors were placed along facility fencelines and in a
grid pattern surrounding the source area, with grid receptors 100
meters apart, in accordance with EPA guidance. The AERMAP preprocessor,
version 06341, a part of the AERMOD modeling system, was used to assign
the elevations for all sources, buildings, and receptors from
topographical data.
Because of their inherently low emissions, many natural gas sources
do not have numerical emission limits in the revised PM10 rules.
Nonetheless, current EPA emission factors were used to model the PM10
emissions from all modeled natural gas combustion units.
Background concentrations taken from local air quality monitoring
data were added to the AERMOD results to account for the contribution
from distant sources or very small local sources that are typically not
explicitly included in the modeling analyses.
For some applications, Indiana performed preliminary screening
modeling using the SCREEN3 model, which gives a conservative 1-hour
average concentration for single sources. Conversion factors were used
to estimate 24-hour and annual average concentration values from the
SCREEN3 results.
a. Clark County
The revised rule for Kimball Office--Borden, formerly Kimball Case
Goods (326 IAC 6.5-2-8), added a second boiler and slightly increased
both boilers' listed MMBtu/hr ratings. Indiana ran the SCREEN3
screening model for the resulting 0.096 lb/hr increase in allowable
PM10 emissions. The maximum SCREEN3 result was 0.36 micrograms per
cubic meter ([mu]g/m\3\) on a 24-hour average and 0.07 [mu]g/m\3\ on an
annual average. These levels are not generally considered likely to
cause or significantly contribute to a modeled exceedance of the PM10
NAAQS of 150 [mu]g/m\3\ (24-hour average) and 50 [mu]g/m\3\ (annual
average). We consider the Kimball Office-Borden rule revision to be
approvable.
b. Dubois County
The revised rule changes the PM10 emission limits for sources at
Jasper Seating Co., Inc., Plant No. 3 (326 IAC 6.5-4-3), and Jasper
Chair Company, Inc. (326 IAC 6.5-4-15). Indiana ran SCREEN3 for the
emission changes at these sources. The SCREEN3 results showed that the
changes at Jasper Seating Co., Inc. had an impact of 1.7 [mu]g/m\3\ on
a 24-hour average and 0.3 [mu]g/m\3\ on an annual average. Jasper Chair
Company, Inc.'s emission changes had an impact of 0.27 [mu]g/m\3\ on a
24-hour average and 0.05 [mu]g/m\3\ on an annual average. PM10
concentration increases of this size are generally considered to be
unlikely to cause or contribute to exceedances of the PM10 NAAQS.
Indiana also used the AERMOD model to evaluate Dubois County's full
PM10 emissions. The AERMOD run included 23 Dubois County facilities.
Surface meteorological data was taken from Evansville, Indiana and
upper air data was taken from Peoria, Illinois, for the five-year
period of 1988 to 1992. The high, second high 24-hour modeled
concentration was 26.8 [mu]g/m\3\, and with the background value of
50.7 [mu]g/m\3\, the final result was 77.5 [mu]g/m\3\, compared to the
24-hour NAAQS of 150 [mu]g/m\3\. The maximum annual modeled
concentration was 3.71 [mu]g/m\3\, and with the annual background
concentration of 26.0, the final result was 29.7 [mu]g/m\3\, compared
to the annual PM10 NAAQS of 50 [mu]g/m\3\. Therefore, the PM10 NAAQS
should be protected under the revised rule, and the revised PM10
emission limits are approvable.
c. Marion County
For International Truck and Engine Corporation & Indianapolis
Casting Corporation, formerly Navistar International, (326 IAC 6.5-6-
26), the rule was revised to reflect the fact that there are three
exhaust stacks that vent the Phase 3 Baghouse emissions. The three
stacks have the same heights, and are within 10 to 15 feet of each
other. Since the vents are so close to each other and similar in size,
EPA does not expect that a dispersion modeling analysis would show an
appreciable difference between the results of modeling the full
emissions from one stack (as the previous rule indicated) and the
results of modeling one third of the full emissions from each of the
three stacks (as the revised rule indicates). Therefore, EPA did not
require Indiana to perform additional modeling for the revised rule for
International Truck and Engine Corporation & Indianapolis Casting
Corporation (326 IAC 6.5-6-26).
For the analysis of the emission limit changes at Vertellus,
Indiana performed dispersion modeling for the facility's emission limit
changes alone, to evaluate their impact. The AERMOD analysis used
surface meteorological data from Indianapolis, Indiana, and upper air
data from Dayton, Ohio, for the five-year period of 1988 to 1992.
Indiana modeled the previous and revised PM10 limits separately for the
Vertellus units affected by the revised rule. The high, second high
modeled 24-hour average PM10 concentration decreased from 21.1 [mu]g/
m\3\ to 14.5 [mu]g/m\3\ under the rule revision. The maximum modeled
annual average PM10 concentration decreased from 1.07 [mu]g/m\3\ to
0.96 [mu]g/m\3\.
Indiana also noted that the closed Chrysler Foundry, formerly
listed at 326 IAC 6.5-6-9, was immediately north of Vertellus. Its
closure reduces the allowable PM10 emissions in the Marion County SIP
by more than 160 tpy. Indiana used AERMOD to evaluate
[[Page 13821]]
the impact of the Chrysler Foundry shutdowns near Vertellus. At
Vertellus' peak receptor locations, the Chrysler Foundry shutdowns
would provide a 33.4 [mu]g/m\3\ 24-hour average reduction and a 2.8
[mu]g/m\3\ annual average reduction. Chrysler Foundry's modeled
reductions are greater than 33.4 [mu]g/m\3\ at several other nearby
receptor locations, and modeled reductions from Chrysler Foundry that
are comparable to Vertellus' modeled impacts occur over a large area.
EPA accepts Indiana's demonstration that the Chrysler Foundry closure
helps offset the emission changes at Vertellus.
d. St. Joseph County
Indiana used AERMOD to evaluate the emission limit changes at the
Reith-Riley and Walsh & Kelly facilities. A total of 55 sources in St.
Joseph County were included in the analysis. The analysis used surface
meteorological data from South Bend, Indiana and upper air data from
Peoria, Illinois for the five-year period of 1988 to 1992. Receptors
were placed in grids centered around the Reith-Riley and Walsh & Kelly
facilities. The maximum high, second high 24-hour concentration, which
occurred near Walsh & Kelly, was 19.0 [mu]g/m\3\. With a background
concentration of 40.3 [mu]g/m\3\, the final result was 59.3 [mu]g/m\3\,
compared to the 24-hour NAAQS of 150 [mu]g/m\3\. The maximum annual
PM10 concentration, which also occurred near Walsh & Kelly, was 1.8
[mu]g/m\3\. With a background concentration of 23.0 [mu]g/m\3\, the
final result was 24.8 [mu]g/m\3\, compared to the annual PM10 NAAQS of
50 [mu]g/m3. Therefore, the PM10 NAAQS should be protected under the
revised rule, and the revised PM10 emission limits are approvable.
e. Lake County
Since only four facilities had increasing emission limits, Indiana
focused its modeling analysis on those sources. EPA modeling guidance
does not require an individual impact analysis for sources with no SIP
emission limit changes, or with emission limit decreases only. First,
Indiana modeled the increasing and decreasing units at BP, to gauge the
impact of the emission limit changes. Generally, a 24-hour average PM10
concentration below 5 [mu]g/m\3\ or an annual average PM10
concentration below 1 [mu]g/m\3\, would not be considered to make a
significant contribution to overall PM10 concentrations. The maximum
24-hour impact from the BP changes was 0.48 [mu]g/m\3\, and the maximum
annual impact from the BP changes was 0.0 [mu]g/m\3\.
Indiana then separately modeled each of the four Lake County
facilities' entire PM10 emissions, with receptors placed in each
facility's region of influence. The maximum 24-hour impact from BP was
5.3 [mu]g/m3, and the maximum annual impact was 0.94 [mu]g/
m3. The maximum 24-hour impact from ASF--Keystone was 58.4
[mu]g/m3, and the maximum annual impact was 11.9 [mu]g/
m3. The maximum 24-hour impact from Resco was 50.8 [mu]g/
m3, and the maximum annual impact was 9.7 [mu]g/
m3. The maximum 24-hour impact from LaSalle Steel was 26.2
[mu]g/m3, and the maximum annual impact was 6.2 [mu]g/
m3.
Finally, Indiana ran the AERMOD model with all Lake County PM10
sources included. The receptor grid for this analysis covered the areas
which were influenced by BP, ASF--Keystone, Resco, and LaSalle Steel.
Background concentrations were added to the AERMOD results, and the
sums were compared to the 24-hour PM10 NAAQS of 150 [mu]g/m3
and the annual PM10 NAAQS of 50 [mu]g/m3. The maximum 24-
hour concentration near BP from all sources, plus background, was 145.7
[mu]g/m3, and the annual concentration near BP, including
background, was 46.8 [mu]g/m3. These concentrations were
also the overall maximum concentrations in the PM10 modeled analysis
for the Lake County facilities. The maximum 24-hour concentration near
ASF--Keystone from all sources, plus background, was 101.4 [mu]g/
m3, and the annual concentration near ASF--Keystone,
including background, was 39.9 [mu]g/m3. The maximum 24-hour
concentration near Resco from all sources, plus background, was 84.8
[mu]g/m3, and the annual concentration near Resco, including
background, was 40.3 [mu]g/m3. The maximum 24-hour
concentration near LaSalle Steel from all sources, plus background, was
76.5 [mu]g/m3, and the annual concentration near LaSalle
Steel, including background, was 35.1 [mu]g/m3. The analysis
showed that the revised emission limits at BP, ASF--Keystone, Resco,
and LaSalle Steel should be protective of the PM10 NAAQS in Lake
County.
VI. What Action Is EPA Taking Today?
EPA is proposing to approve Indiana's February 21, 2008, PM10 SIP
revision request. This submittal includes revisions to 326 IAC 6.5-2,
326 IAC 6.5-3, 326 IAC 6.5-4, 326 IAC 6.5-5, 326 IAC 6.5-6, 326 IAC
6.5-7, 326 IAC 6.5-8, 326 IAC 6.5-9, and 326 IAC 6.5-10, which EPA is
proposing to approve. The submittal also includes revisions to 326 IAC
6.8-1-1, 326 IAC 6.8-1-5, 326 IAC 6.8-1-7, 326 IAC 6.8-2, 326 IAC 6.8-
4-1, 326 IAC 6.8-8-1, 326 IAC 6.8-9-3, and 326 IAC 6.8-10-1, which EPA
is proposing to approve. The submittal reflects the repeal of 326 IAC
6.8-3, 326 IAC 6.8-5, 326 IAC 6.8-6, and 326 IAC 6.8-7, which EPA is
proposing to approve.
The following portions of 326 IAC 6.5 and 6.8 were unchanged by the
February 20, 2008, Indiana Register publication, and therefore they
remain a part of the approved Indiana PM10 SIP: 326 IAC 6.5-1, 326 IAC
6.8-1-1.5, 326 IAC 6.8-1-2, 326 IAC 6.8-1-3, 326 IAC 6.8-1-4, 326 IAC
6.8-1-6, 326 IAC 6.8-8-2 through 326 IAC 6.8-8-8, 326 IAC 6.8-9-1, 326
IAC 6.8-9-2, 326 IAC 6.8-10-2, 326 IAC 6.8-10-3, 326 IAC 6.8-10-4, and
326 IAC 6.8-11.
As noted above, EPA is taking comment on this proposed action. All
adverse comments submitted during the comment period will be responded
to in EPA's final action on this SIP revision. If comments are received
that preclude EPA from rulemaking on portions of the state submittal,
EPA will proceed with rulemaking on other portions of the submittal
that are not the subject of these comments.
VII. Statutory and Executive Order Reviews
Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, September 30, 1993), this
action is not a ``significant regulatory action'' and therefore is not
subject to review by the Office of Management and Budget.
Paperwork Reduction Act
This proposed rule does not impose an information collection burden
under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C.
3501 et seq.).
Regulatory Flexibility Act
This proposed action merely proposes to approve state law as
meeting Federal requirements and imposes no additional requirements
beyond those imposed by state law. Accordingly, the Administrator
certifies that this proposed rule will not have a significant economic
impact on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.).
Unfunded Mandates Reform Act
Because this rule proposes to approve pre-existing requirements
under state law and does not impose any additional enforceable duty
beyond that required by state law, it does not contain any unfunded
mandate or significantly or uniquely affect small governments, as
[[Page 13822]]
described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).
Executive Order 13132: Federalism
This action also does not have Federalism implications because it
does not have substantial direct effects on the states, on the
relationship between the national government and the states, or on the
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132 (64 FR 43255, August
10, 1999). This action merely proposes to approve a state rule
implementing a federal standard, and does not alter the relationship or
the distribution of power and responsibilities established in the Clean
Air Act.
Executive Order 13175: Consultation and Coordination With Indian Tribal
Governments
This proposed rule also does not have tribal implications because
it will not have a substantial direct effect on one or more Indian
tribes, on the relationship between the Federal Government and Indian
tribes, or on the distribution of power and responsibilities between
the Federal Government and Indian tribes, as specified by Executive
Order 13175 (65 FR 67249, November 9, 2000).
Executive Order 13045: Protection of Children From Environmental Health
and Safety Risks
This proposed rule also is not subject to Executive Order 13045
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997), because it proposes approval of
a state rule implementing a Federal Standard.
Executive Order 13211: Actions That Significantly Affect Energy Supply,
Distribution, or
