Recent Posting to the Applicability Determination Index (ADI) 
Database System of Agency Applicability Determinations, Alternative 
Monitoring Decisions, and Regulatory Interpretations Pertaining To 
Standards of Performance for New Stationary Sources, National Emission 
Standards for Hazardous Air Pollutants, and the Stratospheric Ozone 
Protection Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: This notice announces applicability determinations, 
alternative monitoring decisions, and regulatory interpretations that 
EPA has made under the New Source Performance Standards (NSPS); the 
National Emission Standards for Hazardous Air Pollutants (NESHAP); and 
the Stratospheric Ozone Protection Program.

FOR FURTHER INFORMATION CONTACT: An electronic copy of each complete 
document posted on the Applicability Determination Index (ADI) database 
system is available on the Internet through the Office of Enforcement 
and Compliance Assurance (OECA) Web site at: https://www.epa.gov/
compliance/monitoring/programs/caa/adi.html. The letters and memoranda 
may be searched on the ADI by date, office of issuance, subpart, 
citation, control number or by string word searches. For questions 
about the ADI or this notice, contact Maria Malave at EPA by phone at: 
(202) 564-7027, or by e-mail at: malave.maria@epa.gov. For technical 
questions about the individual applicability determinations or 
monitoring decisions, refer to the contact person identified in the 
individual documents, or in the absence of a contact person, refer to 
the author of the document.

SUPPLEMENTARY INFORMATION:

Background:

    The General Provisions to the NSPS in 40 Code of Federal 
Regulations (CFR) part 60 and the NESHAP in 40 CFR part 61 provide that 
a source owner or operator may request a determination of whether 
certain intended actions constitute the commencement of construction, 
reconstruction, or modification. EPA's written responses to these 
inquiries are commonly referred to as applicability determinations. See 
40 CFR 60.5 and 61.06. Although the part 63 NESHAP and section 111(d) 
of the Clean Air Act regulations contain no specific regulatory 
provision that sources may request applicability determinations, EPA 
does respond to written inquiries regarding applicability for the part 
63 and section 111(d) programs. The NSPS and NESHAP also allow sources 
to seek permission to use monitoring or recordkeeping that are 
different from the promulgated requirements. See 40 CFR 60.13(i), 
61.14(g), 63.8(b)(1), 63.8(f), and 63.10(f). EPA's written responses to 
these inquiries are commonly referred to as alternative monitoring 
decisions. Furthermore, EPA responds to written inquiries about the 
broad range of NSPS and NESHAP regulatory requirements as they pertain 
to a whole source category. These inquiries may pertain, for example, 
to the type of sources to which the regulation applies, or to the 
testing, monitoring, recordkeeping or reporting requirements contained 
in the regulation. EPA's written responses to these inquiries are 
commonly referred to as regulatory interpretations.
    EPA currently compiles EPA-issued NSPS and NESHAP applicability 
determinations, alternative monitoring decisions, and regulatory 
interpretations, and posts them on the ADI on a quarterly basis. In 
addition, the ADI contains EPA-issued responses to requests pursuant to 
the stratospheric ozone regulations, contained in 40 CFR part 82. The 
ADI is an electronic index on the Internet with over one thousand EPA 
letters and memoranda pertaining to the applicability, monitoring, 
recordkeeping, and reporting requirements of the NSPS and NESHAP. 
Today's notice comprises a summary of 84 such documents added to the 
ADI on July 11, 2008. The subject, author, recipient, date and header 
of each letter and memorandum are listed in this notice, as well as a 
brief abstract of the letter or memorandum. Complete copies of these 
documents may be obtained from the ADI through the OECA Web site at: 
www.epa.gov/compliance/monitoring/programs/caa/adi.html.

Summary of Headers and Abstracts

    The following table identifies the database control number for each 
document posted on the ADI database system on July 11, 2008; the 
applicable category; the subpart(s) of 40 CFR part 60, 61, or 63 (as 
applicable) covered by the document; and the title of the document, 
which provides a brief description of the subject matter.
    We have also included an abstract of each document identified with 
its control number after the table. These abstracts are provided solely 
to alert the public to possible items of interest and are not intended 
as substitutes for the full text of the documents. This notice does not 
change the status of any document with respect to whether it is ``of 
nationwide scope or effect'' for purposes of section 307(b)(1) of the 
Clean Air Act. Neither does it purport to make any document that was 
previously non-binding into a binding document.

Abstract for [0700029]

    Q: Is Blaine Larsen Farms' (BLF) boiler, located at the Dehydration 
Division potato processing plant in Dubois, Idaho, derated and 
therefore subject to the requirements of 40 CFR part 60, subpart Dc, 
rather than 40 CFR part 60, subpart Db?
    A: Yes. EPA determines that BLF's boiler has been derated and is 
now subject to NSPS subpart Dc, because the burner has been replaced 
with one that will limit the boiler capacity to less than 100 mmBtu/hr, 
as verified by testing, and it meets the four derate criteria, as 
specified in the EPA response letter.

    Q: Has initial startup occurred for a boiler at the Warm Springs

curing.
    A: No. Because the ``Instruction Manual for Clarification of 
Startup in Source Categories Affected by New Source Performance 
Standards'' (EPA-68-01-4143) states that startup is defined as the 
first time steam is produced by the boiler and used to provide heat or 
hot water to run process equipment or to produce electricity, EPA finds 
that the boil-out and curing of the refractory is therefore a pre-
startup activity.

    Q: Is a snowmelter with a rated capacity between 10 and 100 MMBtu/
hr that is operated by the Ted Stevens Anchorage International Airport 
subject to 40 CFR part 60, subpart Dc?
    A: No. EPA determines that NSPS subpart Dc does not apply to 
snowmelters. Although a snowmelter is a device that combusts fuel and 
melts ice resulting in the heating of water, the heated water is not 
being used for transferring heat from one point to another for any 
useful purpose such as heating a building or creating steam to drive a 
process. Therefore, the heated water would not qualify as a heat 
transfer medium.

    Q: Is the Pioneer Natural Resources Alaska, Incorporated (PNRA) 
incineration unit located at its Oooguruk Development Project Offshore 
Drill Site camp on the North Slope, Alaska, exempted from the 
requirements of the NSPS for Commercial and Industrial Solid Waste 
Incineration Units at 40 CFR part 60, subpart CCCC?
    A: Yes. Based on the information submitted in the notification 
required to claim the exemption under 40 CFR Sec.  60.2020(c)(2), EPA 
finds that this incinerator would meet the exemption criteria in 40 CFR 
60.2020(c)(2), and is therefore required to meet the applicable 
recordkeeping requirements established by this provision. The 
incinerator would meet the criteria of burning greater than 30 percent 
municipal solid waste or refuse-derived fuel (as defined in NSPS 
subparts Ea, Eb, AAAA, and BBBB) in its fuel feed stream. This 
incinerator will primarily burn waste generated by a housing camp 
associated with the PNRA facility, along with some industrial packing 
and other non-hazardous waste materials from drilling support 
activities on site.

    Q1: Is Anadarko's double-chamber cyclonator forced-air solid waste 
incinerator with a capacity of 2.4 tons per day, constructed after 
November 1999, that has been seasonally located and intermittently 
operated at remote oil and gas exploration sites on the North Slope of 
Alaska since January 2003, subject to 40 CFR part 60, subpart CCCC?
    A1: Yes, EPA concludes that a waste incinerator with a capacity of 
2.4 tons per day, constructed after November 1999, that has been 
seasonally located and intermittently operated at remote oil and gas 
exploration sites, is subject to NSPS subpart CCCC. EPA considers this 
incinerator to be located at an industrial facility, and even though 
the incinerator may be moved from one location to the next, it will be 
a distinct operating unit of an industrial facility.
    Q2: Is 40 CFR part 61, subpart E, the Mercury NESHAP, applicable to 
an incineration unit that incinerates untreated sanitary waste (solids) 
collected from Pacto toilets at Anadarko's remote oil and gas 
exploration sites on the North Slope of Alaska?
    A2: No. The practice of incinerating sanitary waste composed of 
untreated solids from Pacto toilets does not meet the description of 
incinerating sludge under the Mercury NESHAP. 40 CFR 61.50 states that 
the rule applies to ``those stationary sources which * * * incinerate 
or dry wastewater treatment plant sludge.'' Under 40 CFR 61.51, sludge 
is defined as ``sludge produced by a treatment plant that processes 
municipal or industrial waste waters.'' Thus, the Mercury NESHAP would 
not apply.

    Q1: Does EPA approve the proposal of Roseburg Forest Products (RFP) 
of Roseburg, Oregon, to derate two boilers, regulated under 40 CFR part 
60, subpart D, by eliminating the capacity of both boilers to burn oil 
and replacing the burners with burners that are limited to burning less 
than 250 MMBtu/hr of natural gas, provided that the natural gas 
pressure delivered to the boilers is monitored?
    A1: Yes. EPA believes that the changes made by RFP meet the derate 
criteria because installation of a new burner is a permanent change to 
the boiler, which requires a system shutdown, cannot be easily undone, 
and is not just a change to the fuel feed system. Based on the 
performance test data submitted, EPA has concluded that the capacity of 
the boilers does not exceed the 250 MMBtu/hr applicability threshold, 
provided the pressures are maintained below 9.16 psig for Boiler No. 2 
and 7.33 psig for Boiler No. 6 (calculated using a three-hour average). 
Therefore, Boilers No. 2 and No. 6 are no longer subject to NSPS 
subpart D, if the limits on gas pressure are monitored and maintained 
below the threshold values per the Title V permit.

    Q: Is FEX L.P.'s incineration unit located at FEX L.P.'s Artic Wolf 
Camp for housing associated with its Northwest National Petroleum 
Reserve Exploration Drilling Project on the North Slope, Alaska, 
exempted from the requirements of the NSPS for Commercial and 
Industrial Solid Waste Incineration Units, under 40 CFR part 60, 
subpart CCCC?
    A: Yes. Based on the information submitted in the notification 
required to claim the exemption under 40 CFR

[[Page 44729]]

Sec.  60.2020(c)(2), EPA finds that this incinerator would meet the 
exemption criteria in 40 CFR 60.2020(c)(2), and is therefore required 
to meet the recordkeeping requirements established in this provision. 
The incinerator would meet the exemption criteria of burning greater 
than 30 percent municipal solid waste or refuse-derived fuel (as 
defined in NSPS subparts Ea, Eb, AAAA, and BBBB) in its fuel feed 
stream. This incinerator will burn primarily residential-type waste 
generated by a housing camp and cafeteria facilities that are 
associated with the FEX facility, along with industrial packing and 
other non-hazardous waste materials from drilling support activities on 
site.

    Q1: May Blaine Larsen Farms (BLF) derate its 40 CFR part 60, 
subpart Db boiler at the Dehydration Division potato processing plant 
in Dubois, Idaho, by restricting the fuel-metering valves? This would 
be accomplished with an adjustment to the valve, and the adjustment 
screws would either be locked into place with a locking device that 
requires a special tool to undo or be sealed with epoxy.
    A1: No. EPA determines that this approach would not be valid to 
derate a boiler under NSPS subpart Db for several reasons. Neither 
proposed method for locking the screws would be considered permanent. A 
derate must reduce the capacity of the boiler without the installation 
of a feed rate governor. Changes that are made only to fuel feed 
systems are not acceptable for a derate.
    Q2: May Blaine Larsen Farms derate its 40 CFR part 60, subpart Db 
boiler by replacing the burner?
    A2: Yes. EPA finds that the replacement of the burner is an 
acceptable method to derate a burner under NSPS subpart Db since it 
meets the deration criteria, including: (1) It is a change that cannot 
be easily undone, (2) requires a system shutdown to accomplish or 
reverse, and (3) it is not just a change to the fuel feed system.
    Q3: May the American Society of Mechanical Engineers Performance 
Test, Code 4-1998, be used as the verification test method to 
demonstrate a derate has been accomplished under 40 CFR part 60, 
subpart Db?
    A3: Yes. EPA finds that this method has been used before to 
successfully demonstrate that a derate has been accomplished under NSPS 
subpart Db.
    Q4: Is Blaine Larsen Farms test protocol verification method 
acceptable to demonstrate that a derate has been accomplished under 40 
CFR part 60, subpart Db?
    A4: Yes. EPA determines that the results of the protocol 
verification method would be acceptable under NSPS subpart Db if BLF 
continuously monitors fuel feed rates and maintains information 
regarding the fuel heat content in order to ensure that the unit does 
not exceed 100 mmBtu/hr of heat input.

Abstract for [0700037]

    Q1: Does EPA approve the use of a certified nitrogen oxide 
continuous emission monitoring system (NOX CEMS) to document 
compliance with 40 CFR part 60, subpart GG NOX limit in lieu 
of a performance test for compliance analysis after the new fuel is 
introduced for stationary gas turbines operated by Klamath Energy, LLC 
of Portland, Oregon?
    A1: Yes. EPA conditionally approves the use of a certified 
NOX CEMS because it finds that as long as the provisions of 
40 CFR Sec.  60.334(b) are followed, CEMS are enough to satisfy 
compliance with the emission limit for NOX. 40 CFR Sec.  
60.334(g) states that a performance test is required only when 
equipment parameters need to be established.
    Q2: Does EPA waive fuel nitrogen content monitoring of 40 CFR part 
60, subpart GG, if part 75 NOX CEMS are used for the Klamath 
Energy plant?
    A2: EPA finds that whether or not the turbine is also subject to 
part 75, the fuel nitrogen content monitoring is waived only if the 
NOX emission allowance in the equations used to determine 
the NSPS subpart GG NOX emission standards in 40 CFR Sec.  
60.332 is not claimed.
    Q3: Does EPA waive the 40 CFR part 60, subpart GG requirement for 
water-to-fuel injection ratio monitoring because of the use of the part 
75 certified CEMS for the Klamath Energy plant?
    A3: Yes. EPA finds that under 40 CFR Sec.  60.334(b) the owner or 
operator may, as an alternative to water-to-fuel injection monitoring, 
install, certify, maintain, operate, and quality assure a CEMS if the 
provisions of 40 CFR Sec.  60.334(b) are followed.
    Q4: Does EPA approve the use of vendor analyses under 40 CFR part 
60, subpart GG, for monitoring sulfur content of the fuel oil burned 
for the Klamath Energy plant?
    A4: Yes. EPA conditionally approves the use of vendor analyses 
since it finds that under 40 CFR 60.334(i)(1), the fuel oil sampling 
for total sulfur content can be done at each delivery. Oil sampling may 
be performed by a fuel supplier, provided that the sampling is 
performed according to either the single tank composite sampling 
procedure or the all-levels sampling procedure in ASTM D4057-88.

    Q: Does EPA approve the request from the St. Luke's Meridian 
Medical Center (SLMMC) facility in Meridian, Idaho, for a reduction in 
the submittal frequency of the fuel emission reports from semiannually 
to annually, for two boilers (Boilers No. 1 and No. 2) at the facility 
under 40 CFR part 60, subpart Dc?
    A: Yes. EPA conditionally approves a reduction in the submittal 
frequency of the fuel emission reports from semiannually to annually on 
the basis that SLMMC receives only one shipment of distillate oil per 
year. SLMMC shall submit all fuel supplier certifications as described 
in 40 CFR 60.48(f)(1), postmarked by the last day of January of each 
year. If any additional shipments of fuel are received during the year, 
the fuel supplier certification will be submitted to the Idaho 
Department of Environmental Quality within 30 days. Each annual report 
shall include a certified statement signed by the owner or operator of 
SLMMC's facility that the fuel supplier certifications attached to the 
report represent all of the distillate oil received by SLMMC for the 
purposes of fueling the above-referenced boilers during the reporting 
period.

    Q1: Does EPA approve a request from Gossner Foods (Gossner) for a 
reduction in the fuel usage recordkeeping requirement in 40 CFR 60.48c 
from daily to monthly for Gossner's two boilers in Heyburn, Idaho, 
which fire natural gas as the primary fuel and propane as a backup 
fuel?
    A1: Yes. EPA approves this request based on a memorandum dated 
February 20, 1992, from the EPA Office of Air Quality Planning and 
Standards, which states that there is little value in requiring daily 
recordkeeping of the amounts of fuel combusted for an affected unit 
that fires only natural gas under NSPS subpart Dc. This is because 
subpart Dc does not have any emission limitations for units that fire 
only natural gas. Therefore, the purpose of this recordkeeping is to 
verify that only natural gas is fired. Propane is considered to be a 
type of natural gas.
    Q2. Does EPA approve a request from Gossner to use one gas meter to 
record monthly natural gas and/or propane usage for Gossner's two 
boilers?
    A2: Yes. EPA approves this request. EPA finds that the Gossner 
proposal to divide each boiler design heat input capacity by the total 
of the design heat

[[Page 44730]]

input capacities of each boiler, and use this to prorate the natural 
gas and/or propane usage of each boiler on a monthly basis, when more 
than one boiler is firing natural gas and/or propane simultaneously, 
will adequately determine the natural gas and/or propane usage by each 
boiler.

Abstract for [0700040]

    Q: Does EPA approve an alternative plan for monitoring opacity at 
the Basic American Foods (BAF) facility in Blackfoot, Idaho, in lieu of 
a Continuous Opacity Monitoring System (COMS), under 40 CFR part 60, 
subpart Dc, where the COMS will not provide accurate measurements due 
to water vapor from a proposed wet scrubber?
    A: Yes. According to the provisions of 40 CFR 60.13(h)(i)(1), a 
written application for alternative opacity monitoring requirements can 
be submitted when ``installation of a continuous emission monitoring 
system or monitoring device specified by this part would not provide 
accurate measurement due to liquid water or other interferences caused 
by substances with the effluent gasses.'' EPA has previously approved 
similar requests, which are posted on EPA's applicability determination 
index. (See EPA Determination Control Numbers 0000010 and 0300073.) In 
previous requests, EPA has determined that the continuous monitoring of 
the scrubbing liquid flow rate and the pressure drop of the gas stream 
across the scrubber is acceptable as an alternative monitoring to the 
COMS. EPA approves the alternative monitoring plan that the Idaho 
Department of Environmental Quality has recommended and BAF has agreed 
to.

    Q1: Does EPA approve monthly instead of daily monitoring of 
exclusive use of low-sulfur distillate oil in a 40 CFR part 60, subpart 
Dc affected boiler operated by Hampton Lumber Mill at a facility in 
Darrington, Washington?
    A1: Yes. EPA approves monthly instead of daily monitoring of 
exclusive use of low-sulfur distillate oil in an NSPS subpart Dc 
affected boiler.
    Q2: For this same facility, does EPA approve the use of fuel 
receipts from a low-sulfur distillate oil supplier as a monthly 
monitoring method under 40 CFR part 60, subpart Dc?
    A2: Yes. EPA approves the use of fuel receipts from a low-sulfur 
distillate oil supplier as a monthly monitoring method under NSPS 
subpart Dc.
    Q3: Does EPA find that the amount of low-sulfur distillate oil used 
at that facility can be divided evenly between two similar boilers 
under 40 CFR part 60, subpart Dc?
    A3: Yes. EPA finds that the amount of low-sulfur distillate oil 
used at a facility can be divided evenly between two similar boilers 
under NSPS subpart Dc, as long as they have the same rated capacity and 
operate in a way that emissions from either boiler are substantially 
similar if based on the same amount of fuel.

Abstract for [0700042]

    Q: Do changes proposed by Roseburg Forest Products (RFP) to two 
large boilers in Dillard, Oregon, result in the boilers being derated 
under 40 CFR part 60, subpart D? RFP has eliminated the capacity of 
both boilers to burn oil and made changes to the boilers that reduce 
the total heat input capacity for both boilers to less than 245.7 
MMBtu/hr for natural gas. RFP proposed to conduct additional monitoring 
and performance testing to verify that the capacity of the boilers has 
been reduced.
    A: Although the changes RFP has made to its boilers appear to meet 
many of the criteria for derating boilers, EPA requires submission of 
source test data verifying that the capacity of the boilers has been 
reduced before EPA will determine that the RFP boilers have been 
derated. Any such verification testing should be conducted while each 
boiler is operating at its maximum capacity for a 24-hour period for 
each fossil fuel that the boiler has the capability of burning. EPA 
expects RFP to monitor the gas pressure during the performance test to 
verify the correlation of gas pressure to heat input. In addition, to 
ensure reliability of the performance test results, RFP should submit a 
performance test plan to EPA for approval prior to the test and follow 
the general provisions of 40 CFR part 60, subpart A, for performance 
tests, such as notifying EPA in advance of the test.

    Q1: Does EPA approve monthly instead of daily monitoring of natural 
gas usage in a 40 CFR part 60, subpart Dc affected boiler at the 
proposed J. R. Simplot Company facility near Mountain Home, Idaho?
    A1: Yes. EPA approves monthly instead of daily monitoring of 
natural gas usage in this NSPS subpart Dc affected boiler.
    Q2: Does EPA approve the use of fuel receipts from a gas supplier 
to serve as a monthly monitoring method under 40 CFR part 60, subpart 
Dc, for an affected boiler at the proposed J. R. Simplot Company 
facility near Mountain Home, Idaho?
    A2: Yes. EPA approves the use of fuel receipts from a gas supplier 
to serve as monthly monitoring method under NSPS subpart Dc.
    Q3: Does EPA find that all of the natural gas used at a facility 
can be attributed to the 40 CFR part 60, subpart Dc affected boilers, 
if there is some gas used by a unit that is a facility not covered by 
any other regulation, as proposed by the J. R. Simplot Company facility 
near Mountain Home, Idaho?
    A3: Yes. EPA finds that all of the natural gas used at a facility 
can be attributed to the NSPS subpart Dc affected boilers, even if 
there is some gas used by another unit, as long as that other unit is a 
facility not covered by any other regulation.
    Q4: Does EPA find that the amount of natural gas used at a facility 
can be divided evenly between two similar boilers under 40 CFR part 60, 
subpart Dc, as proposed by the J. R. Simplot Company facility near 
Mountain Home, Idaho?
    A4: Yes. EPA finds that the amount of natural gas used at a 
facility can be divided evenly between two similar boilers under NSPS 
subpart Dc, as long as they have the same rated capacity and operate in 
a way that emissions from either boiler are substantially similar if 
based on the same amount of fuel.

    Q: Is the Anchorage Water and Wastewater Utility (AWWU) subject to 
40 CFR part 60, subpart O, based on changes and upgrades that are 
planned for the emission control system on AWWU's multiple hearth 
sludge furnace (MHF) at the Asplund Wastewater Treatment Facility?
    A: EPA determines that the MHF continues to be subject to NSPS 
subpart O. The MHF was constructed in 1986 and is subject to NSPS 
subpart O, which is applicable to a facility constructed after June 11, 
1973. The upgrades to AWWU's facility do not affect applicability 
status because the facility is already subject to NSPS subpart O based 
on the date of construction.

    Q: Does EPA grant a waiver to Flint Hills Resources Alaska of the 
30-day notification of performance evaluation for recently installed 
sulfur dioxide (SO2) Continuous Emission Monitoring System 
according to 40 CFR 60.7(a)(5) and 60.8(d)?
    A: Yes. EPA grants a waiver of the 30-day notification of 
performance evaluation, under 40 CFR 60.19(f)(3), because of the need 
to meet deadlines

[[Page 44731]]

that have been laid out in a Compliance Order by Consent.

    Q: Is Anadarko Petroleum Corporation's incineration unit at the 
Jacobs Ladder Exploration Drilling Project on the North Slope, Alaska, 
exempted from the requirements of 40 CFR part 60, subpart CCCC?
    A: Based on the information submitted in the notification required 
to claim the exemption under 40 CFR 60.2020(c)(2), EPA finds that this 
incinerator would meet the exemption criteria in 40 CFR 60.2020(c)(2), 
and is therefore required to meet the recordkeeping requirements 
established in this provision. Under 40 CFR 60.2020(c)(2), an exemption 
is provided for units that burn greater than 30 percent municipal solid 
waste or refuse-derived fuel (as defined in NSPS subparts Ea, Eb, AAAA, 
and BBBB) in their fuel feed stream. This incinerator will burn 
primarily residential-type waste generated by a housing camp and 
cafeteria facilities that is associated with the Anadarko facility, 
along with some industrial packing and other non-hazardous waste 
materials from drilling support activities on site.

Abstract for [0700047]

    Q: Does EPA approve a reduction in the submittal frequency of the 
fuel emission reports to annually for two boilers using natural gas, 
except for approximately eight hours per month when diesel fuel is used 
as a backup, under 40 CFR part 60, subpart Dc, at the St. Luke's 
Regional Medical Center in Boise, Idaho?
    A: Yes. EPA approves a reduction in the submittal frequency of the 
fuel emission reports to annually. For a boiler that only fires natural 
gas and distillate oil with sulfur content of less than 0.5 percent, 
these reports consist only of fuel oil suppliers' certifications and a 
certified statement of the owner or operator. Because this facility 
receives only one shipment of distillate oil per year, it would be 
redundant to require more than annual submittal of this information. As 
long as the facility receives only one shipment of distillate oil a 
year, it shall submit all fuel supplier certifications as described in 
40 CFR 60.48(f)(1), postmarked by the last day of January of each year.

    Q1: Does EPA approve a reduction in the fuel usage recordkeeping 
requirement in 40 CFR part 60, subpart Dc, from daily to monthly when 
only pipeline quality natural gas is and will be fired in two boilers 
operated by Boise Paper Solutions of Boise Cascade Corporation?
    A1: Yes. EPA approves a reduction in the fuel usage recordkeeping 
requirement in 40 CFR 60.48c from daily to monthly when only pipeline 
quality natural gas is and will be fired in the boilers.
    Q2: Does EPA approve the use of monthly natural gas bills to 
fulfill the recordkeeping requirement in 40 CFR part 60, subpart Dc as 
proposed by Boise Paper Solutions of Boise Cascade Corporation?
    A2: Yes. EPA approves the use of monthly natural gas bills to 
fulfill the recordkeeping requirement of 40 CFR 60.48c, provided that 
all natural gas on the fuel receipt is attributed to use in the two 
boilers, regardless of the small amount that may be used for other 
purposes, such as space heating, and that the amount of natural gas 
used in each boiler is apportioned in equal proportions.

    Q: Does EPA approve a reduction in the monitoring schedule for fuel 
gas sulfur content from quarterly to semiannually under 40 CFR part 60, 
subpart GG, at Calpine Hermiston Power Plant in Oregon, based upon 
demonstrated compliance and low variability for six quarters?
    A: Yes. EPA approves this alternative fuel monitoring request. In 
addition, based on amendments to NSPS subpart GG, promulgated on July 
8, 2004, the requirement to monitor the sulfur content of natural gas 
may be waived.

Abstract for [0700050]

    Q: Does EPA approve a source test protocol for determinations of 
the maximum heat input for use in a boiler derate demonstration, under 
40 CFR part 60, subpart D, at the Roseburg Forest Products facility in 
Roseburg, Oregon?
    A: Yes. Based upon a review of the source test protocol and the 
Piping and Instrument Diagram for the natural gas systems for both 
boilers, EPA concludes that, under NSPS subpart D, if the source test 
is conducted according to the protocol, it should provide the 
information required to verify the maximum heat input, namely, gas flow 
rate, calorific value, and supply pressure.

Abstract for [0700051]

    Q: May a ``bag counting'' surrogate method for determining the 
weight of incinerated waste be used to determine whether the co-fired 
combustor exemption of 40 CFR part 60, subpart Ec, applies to a BP 
Exploration Alaska Incorporated waste incinerator located at the 
Northstar Development Facility in the Beaufort Sea?
    A: No. EPA finds that the surrogate method described will not 
provide the accuracy required by the recordkeeping requirements of NSPS 
subpart Ec. It is not clear from the request whether a distinction is 
made between the differences in the weight of a typical bag of hospital 
and medical/infectious waste and the weight of a typical bag of other 
waste. Also, if an average weight of a bag of hospital and medical/
infectious waste is used, this may underestimate the actual amount of 
hospital and medical/infectious waste that is being burned. Thus, EPA 
has determined that the proposed surrogate method cannot be used for 
the determination of whether the co-fired combustor exemption in 40 CFR 
60.50c(c) is met. EPA will consider a different weight surrogate method 
that adequately ensures that the exemption is met with a margin for 
error.

    Q1: Does the addition of storage capacity, which did not increase 
the hourly grain handling capacity, trigger applicability of 40 CFR 
part 60, subpart DD, for the Busch Agricultural Resources, Incorporated 
(BARI) Malt Plant Facility in Idaho Falls, Idaho?
    A1: Yes. EPA determines that the increase in storage capacity 
triggers NSPS subpart DD applicability. The grain storage capacity 
exceeded 2.5 million bushels in 2002 when the permanent storage 
capacity was increased to 4 million bushels. Because the permanent 
storage capacity for this facility exceeds 2.5 million bushels, the 
facility meets the definition of a grain terminal elevator, as defined 
in NSPS subpart DD, and is subject to the NSPS. In addition, 
60.304(b)(4) of subpart DD, which states that ``the installation of 
permanent storage capacity without an increase in hourly grain handling 
capacity by itself would not be considered a modification of an 
existing facility'', does not apply to BARI. Section 60.304(b)(4) of 
subpart DD does not apply to those affected facilities that are 
constructed at the time applicability was triggered or subsequent to 
that time.
    Q2: Is 40 CFR part 60, subpart DD, applicable to the following 
activities and equipment at the BARI Idaho Falls Malt Plant Facility in 
Idaho Falls, Idaho:
    (1) Malt load out operations;
    (2) Residual/byproduct storage and load out operations;
    (3) Conveyors located inside the malt house that are used to move 
barley and off-kiln malt through the malt house operation; and

[[Page 44732]]

    (4) A baghouse filter that is dedicated solely to controlling dust 
emissions from grain and malt handling within the malt house operation.
    A2: EPA determines the applicability for each of the specific 
activities and equipment at BARI, as follows:
    (1) NSPS subpart DD is not applicable to malt load out operations.
    (2) NSPS subpart DD is not applicable to the storage and load out 
operations of residuals or byproducts provided it is not possible for 
these operations to handle grain. Reject hulls, grain fragments or dirt 
that is handled and stored separately, as well as malted barley and 
malting by-products, are not considered grain.
    (3) Equipment being used is subject to NSPS subpart DD if it 
handles unmalted barley part of the time, and malted and unmalted 
barley at the same time because it is handling some amount of grain, as 
well as conveyors located inside the malt house that are used to move 
unmalted barley. However, conveyors located inside the malt house that 
are used to move off-kiln malt are not subject to NSPS subpart DD.
    (4) Emissions from a baghouse that is controlling dust from grain 
and malt handling within the malt house operation are subject to NSPS 
subpart DD, because the commingled emissions include grain handling 
emissions that are subject to NSPS subpart DD.

    Q: Does the incineration of pharmaceutical wastes disposed of by 
Providence Alaska Medical Center, a hospital in Alaska, require an 
incineration facility, under 40 CFR part 60, subpart Ec, or 40 CFR part 
62, subpart HHH, to demonstrate compliance with Hospital/Medical/
Infectious Waste Incinerator (HMIWI) rules?
    A: Yes. EPA finds the HMIWI regulation applies to the incineration 
of hospital, medical, and infectious wastes. EPA defines ``hospital 
waste'' broadly, and it includes any waste or discarded materials 
generated at a hospital, except unused items returned to the 
manufacturer. Thus, pharmaceutical wastes generated at a hospital and 
disposed of by the hospital are considered ``hospital waste'' under the 
rules, and a facility that incinerates such waste is subject to HMIWI.

    Q: Does EPA approve an alternative monitoring plan in lieu of the 
continuous opacity monitoring (COMS) requirements of 40 CFR 
60.105(a)(1) and corresponding requirements of 40 CFR part 63, subpart 
UUU, where a wet scrubber is to be installed on Puget Sound Refining's 
(PSR's) fluidized catalytic cracking unit (FCCU) in Anacortes, 
Washington?
    A: Yes. EPA approves the monitoring of the liquid flow rate and gas 
flow rate for the wet gas scrubber, which is a jet-ejector design. 
Calculation of the liquid-to-gas ratio must be done as outlined in 
Tables 2 and 3 of Maximum Achievable Control Technology (MACT) subpart 
UUU, except that for purposes of determining and reporting excess 
emissions for the FCCU, a 3-hour rolling average of the liquid-to-gas 
ration will be used.

    Q: Does EPA allow the use of an alternate performance test method 
for stationary gas turbines, under 40 CFR part 60, subpart GG, at 
ConocoPhillips Alaska Incorporated's Alpine Development Project in 
North Slope Alaska?
    A: Yes. EPA approves the use of an alternate performance test 
method, under NSPS subpart GG, only if the probe is designed and 
conforms to the tests specified in EPA Guidance Document CG-031.

    Q1: Should an incinerator used to dispose of camp wastes at a 
remote, temporary work camp in Nuiqsut, Alaska, and operated by Alaska 
Interstate Construction, LLC (AIC), be subject to 40 CFR part 62, 
subpart III, the Federal Plan Requirements for Commercial Industrial 
Solid Waste Incinerators (CISWI)?
    A1: Yes. EPA determines that the work camp is an integral part of a 
commercial operation, the AIC facility, and would not be there but for 
generating profit as a commercial operation under 40 CFR part 62, 
subpart III. The term ``commercial facility'' is not defined in the 
CISWI regulation, but the American Heritage Dictionary defines 
commercial as ``having profit, success, or immediate results as [a] 
chief aim.'' Thus, the work camp incinerator would be considered to be 
located at a ``commercial or industrial facility'' and would be subject 
to CISWI.
    Q2: Should AIC's work camp incinerator, which burns primarily 
municipal solid waste, be regulated under 40 CFR part 62, subpart III?
    A2: Yes. EPA finds that the incinerator should be regulated under 
CISWI. The fact that the waste incinerated is considered to be 
municipal solid waste does not mean that the incinerator would not be 
considered to be a CISWI unit. This is apparent because of the 
exemption that is provided for CISWI units under 40 CFR 62.14525(c)(2) 
for units that burn greater than 30 percent municipal solid waste. 
AIC's work camp incinerator is considered to be a CISWI, but because it 
burns greater than 30 percent municipal solid waste, it has an 
exemption under NSPS subpart III.

    Q: Does EPA find that a coal transloader located in Port Wentworth, 
Georgia, next to Georgia Power's Plant Kraft Steam-Electric Generating 
Plant, and a coal preparation plant, which provides coal to the Plant 
Kraft units, are subject to 40 CFR part 60, subpart Y?
    A: No. EPA has determined that the transloader is not part of the 
coal preparation plant on the property since it not connected to any of 
its breaking, crushing, screening, wet or dry cleaning, or thermal 
drying equipment, and thus is not subject to NSPS subpart Y. Since the 
coal preparation plant was constructed prior to the applicability date 
of October 24, 1974, it is not subject to NSPS subpart Y.

    Q: Is the installation of three solvent-based laminators at the 
Catalyst International's rotogravure urethane coating line and printing 
operations, located in Delaware County, Pennsylvania, subject to 40 CFR 
part 60, subpart FFF?
    A: Yes. EPA has determined that because the two new laminators to 
be installed at Catalyst's Pennsylvania facility will coat a urethane 
web, on a continuous basis, with an adhesive that meets the definition 
of ink given in the NSPS subpart FFF rule using a gravure cylinder, 
these laminators are subject to NSPS subpart FFF.

    Q: Does EPA approve an alternative monitoring plan for boilers 1 
and 2 that fire fuels with low sulfur content at the Hercules' 
Franklin, Virginia plant under 40 CFR part 60, subpart Dc?
    A: EPA approves the alternative fuel sampling methodology for 
Hercules' boiler 2. Hercules may use fuel supplier certifications in 
lieu of a continuous opacity monitor (COM) to prove that very low 
sulfur fuels are being combusted, and get relief from particulate 
emission monitoring pursuant to 40 CFR 60.47c(a). EPA disapproved the 
alternative monitoring proposal for Hercules' boiler 1 to use scrubber 
parametric monitoring in lieu of installing a COM. Hercules will need 
to install a particulate matter (PM) continuous emission monitoring 
system

(CEMS) unless it can show that this is not a viable alternative to a 
COM.

    Q1. Does EPA approve a request to deviate from the assumption that 
a violation of the hydrogen chloride (HCl) emission occurs if the 
Curtis Bay Energy facilities in Baltimore, Maryland, operate their 
Hospital/Medical/Infectious Waste Incinerators (HMIWIs) above the 
maximum charge rate and below the minimum HCl sorbent flow rate 
simultaneously, as stated in 40 CFR part 60, subpart Ec, at Sec.  
60.56c(e)(3)? The facilities have actual hydrogen chloride (HCl) 
emissions data from an EPA compliant continuous HCl emissions monitor 
on a real-time basis.
    A1. Yes. EPA agrees that the actual data, obtained from an EPA 
compliant continuous HCl monitor on a real-time basis, that shows HCl 
emissions are within the allowable limit of either 100 parts per 
million by volume adjusted to 7 percent oxygen measured on a dry basis 
at standard conditions or 93 percent reduction, is superior to using 
surrogate parameter of HCl sorbent flow rate. An EPA compliant 
continuous HCl monitor must meet Performance Specification 2 in 40 CFR 
part 60, specifically the Specifications and Test Procedures for 
SO2 and NOX Continuous Emission Monitoring 
Systems in Stationary Sources in Appendix B, and the quality assurance 
procedures specified in Appendix F, including the revised Relative 
Accuracy Test Audit (RATA) calculation procedures in Enclosure 1 of the 
response letter. In addition, a CEMS for oxygen must be installed, 
calibrated, maintained, and operated in accordance with the 
requirements of Appendices B and F of part 60. EPA describes additional 
requirements applicable for CEMS in the EPA response letter and its 
Enclosure 1.
    Q2. Does EPA approve a request to eliminate the operating parameter 
monitoring requirements for maximum charge rate as specified in Sec.  
60.57c(a) and Table 3 of 40 CFR part 60, subpart Ec, at the Curtis Bay 
Energy Hospital/Medical/Infectious Waste Incinerators (HMIWIs) located 
in Baltimore, Maryland?
    A2. No. EPA finds that the maximum charge rate is an operating 
parameter used to determine compliance with other applicable emission 
limits in addition to HCl emission limits. The definition for maximum 
charge rate given in Sec.  60.51c of 40 CFR for a continuous and 
intermittent HMIWI is ``* * * 110 percent of the lowest 3-hour average 
charge rate measured during the most recent performance test 
demonstrating compliance with all applicable emission limits.'' By 
definition, the maximum charge rate is linked to compliance with all 
applicable emission limits which include particulate matter (PM), 
carbon monoxide (CO), dioxins/furans, HCl, lead (Pb), cadmium (Cd), 
mercury (Hg), sulfur dioxide (SO2), nitrogen oxides 
(NOX), and opacity. EPA will not grant approval to eliminate 
monitoring of the maximum charge rate as an operating parameter since 
it is linked to all emission limits and not linked only to HCl 
emissions.
    Q3. Does EPA approve a request to eliminate the operating parameter 
monitoring requirements for minimum hydrogen chloride (HCl) sorbent 
flow rate as specified in Sec.  60.57c(a) and Table 3 of 40 CFR part 
60, subpart Ec, at the Curtis Bay Energy Hospital/Medical/Infectious 
Waste Incinerators (HMIWIs) located in Baltimore, Maryland?
    A3. Yes. EPA conditionally approves the request to eliminate 
monitoring the minimum HCl sorbent flow rate as an operating parameter 
when the HCl emissions are measured using an EPA compliant continuous 
HCl monitor, as described in the EPA response letter.
    Q4. Does EPA approve a request to eliminate the recordkeeping 
requirements for HMIWI charge dates, times, and weights and hourly 
charge rates as specified in Sec.  60.58c(b)(2)(iii) in 40 CFR part 60, 
subpart Ec, at the Curtis Bay Energy HMIWIs, located in Baltimore, 
Maryland?
    A4. No. EPA finds that, as previously stated in the answer to 
question 2 of this determination, the maximum charge rate parameters 
are linked to other emission limits besides HCl emission limits.
    Q5. Does EPA approve a request to eliminate the recordkeeping 
requirements for the amount and type of HCl sorbent used during each 
hour of operation as specified in Sec.  60.58c(b)(2)(vii) in 40 CFR 
part 60, subpart Ec, at the Curtis Bay Energy HMIWIs located in 
Baltimore, Maryland?
    A5. Yes. EPA agrees that actual data from an EPA compliant 
continuous HCl monitor, as described in the EPA response letter, will 
provide HCl emissions information better than using surrogate 
parameters such as amount and type of HCl sorbent.

    Q: Does EPA approve an alternative opacity monitoring procedure, 
under 40 CFR part 60, subpart Db, for an auxiliary boiler at the 
Cardinal Power Plant, located in Brilliant, Ohio, that has a design 
heat input capacity of 652.58 million British Thermal Units per hour 
and that combusts only number 2 fuel oil?
    A: Yes. EPA conditionally approves this alternative opacity 
monitoring procedure under NSPS subpart Db, and states the conditions 
and requirements of the approval in the EPA response letter.

    Q: Does EPA find that condition three of the March 15, 2006, 
Approval, related to visible emission readings by a certified observer 
using Method 9 at the auxiliary boiler stack, apply to four hours of 
continuous operation or cumulative operation under CFR part 60, 
Appendix A, at the Cardinal Operating Company's facility in Brilliant, 
Ohio?
    A: Yes. EPA finds that condition three applies to four hours of 
continuous operation under NSPS subpart A.

    Q: Is the proposed reduction in the monitoring frequency for the 
321-M machining room at the Savannah River Company's facility in Aiken, 
South Carolina, acceptable under 40 CFR part 60, subpart H?
    A: Yes. EPA finds that replacing continuous monitoring with 
quarterly confirmatory sampling to verify low emissions is acceptable 
under NSPS subpart H, based upon review of data submitted with the 
proposal.
