Current through Register Vol. 48, No. 38, September 20, 2024
a)
Coatings, Inks and Fountain Solutions
The following test methods and procedures shall be used to
determine compliance of as applied coatings, inks, and fountain solutions with
the limitations set forth in this Part.
1) Sampling: Samples collected for analyses
shall be one-liter taken into a one-liter container at a location and time such
that the sample will be representative of the coating as applied (i.e., the
sample shall include any dilution solvent or other VOM added during the
manufacturing process). The container must be tightly sealed immediately after
the sample is taken. Any solvent or other VOM added after the sample is taken
must be measured and accounted for in the calculations in subsection (a)(3) of
this Section. For multiple package coatings, separate samples of each component
shall be obtained. A mixed sample shall not be obtained as it will cure in the
container. Sampling procedures shall follow the guidelines presented in:
A) ASTM D 3925-81 (1985) standard practice
for sampling liquid paints and related pigment coating. This practice is
incorporated by reference in Section 218.112 of this Part.
B) ASTM E 300-86 standard practice for
sampling industrial chemicals. This practice is incorporated by reference in
Section 218.112 of this Part.
2) Analyses: The applicable analytical
methods specified below shall be used to determine the composition of coatings,
inks, or fountain solutions as applied.
A)
Method 24 of 40 CFR 60, appendix A, incorporated by reference in Section
218.112 of this Part, shall be used to determine the VOM content and density of
coatings. If it is demonstrated to the satisfaction of the Agency and the USEPA
that plant coating formulation data are equivalent to Method 24 results,
formulation data may be used. In the event of any inconsistency between a
Method 24 test and a facility's formulation data, the Method 24 test will
govern.
B) Method 24A of 40 CFR 60,
appendix A, incorporated by reference in Section 218.112 of this Part, shall be
used to determine the VOM content and density of rotogravure printing inks and
related coatings. If it is demonstrated to the satisfaction of the Agency and
USEPA that the plant coating formulation data are equivalent to Method 24A
results, formulation data may be used. In the event of any inconsistency
between a Method 24A test and formulation data, the Method 24A test will
govern.
C) The following ASTM
methods are the analytical procedures for determining VOM:
i) ASTM D 1475-85: Standard test method for
density of paint, varnish, lacquer and related products. This test method is
incorporated by reference in Section 218.112 of this Part.

trichloroethane in paints and coatings by direct injection into a gas
chromatograph. (The procedure delineated above can be used to develop protocols
for any compounds specifically exempted from the definition of VOM.) This test
method is incorporated by reference in Section 218.112 of this Part.
vi) ASTM D 2697-86: Standard test method for
volume non-volatile matter in clear or pigmented coatings. This test method is
incorporated by reference in Section 218.112 of this Part.
vii) ASTM D 3980-87: Standard practice for
interlaboratory testing of paint and related materials. This practice is
incorporated by reference in Section 218.112 of this Part.
viii) ASTM E 180-85: Standard practice for
determining the precision data of ASTM methods for analysis of and testing of
industrial chemicals. This practice is incorporated by reference in Section
218.112 of this Part.
ix) ASTM D
2372-85: Standard method of separation of vehicle from solvent-reducible
paints. This method is incorporated by reference in Section 218.112 of this
Part.
D) Use of an
adaptation to any of the analytical methods specified in subsections (a)(2)(A),
(B), and (C) of this Section may not be used unless approved by the Agency and
USEPA. An owner or operator must submit sufficient documentation for the Agency
and USEPA to find that the analytical methods specified in subsections
(a)(2)(A), (B), and (C) of this Section will yield inaccurate results and that
the proposed adaptation is appropriate.
3) Calculations: Calculations for determining
the VOM content, water content and the content of any compounds which are
specifically exempted from the definition of VOM of coatings, inks and fountain
solutions as applied shall follow the guidance provided in the following
documents:
A) "A Guide for Surface Coating
Calculation", EPA-340/1-86-016, incorporated by reference in Section 218.112 of
this Part.

1) The protocol for testing, including
determining the transfer efficiency of coating applicators, at primer surfacer
operations and topcoat operations at an automobile or light-duty truck assembly
source shall follow the procedures in the following:
A) Prior to May 1, 2012: "Protocol for
Determining the Daily Volatile Organic Compound Emission Rate of Automobile and
Light-Duty Truck Topcoat Operations" ("topcoat protocol"), December 1988,
EPA-450/3-88-018, incorporated by reference in Section 218.112 of this
Part.
B) On and after May 1, 2012:
"Protocol for Determining the Daily Volatile Organic Compound Emission Rate of
Automobile and Light-Duty Truck Primer-Surfacer and Topcoat Operations"
(topcoat protocol), September 2008, EPA-453/R-08-002, incorporated by reference
in Section 218.112 of this Part.
2) Prior to testing pursuant to the
applicable topcoat protocol, the owner or operator of a coating operation
subject to the topcoat or primer surfacer limit in Section 218.204(a)(1)(B),
(a)(1)(C), (a)(2)(B), (a)(2)(C), or (a)(2)(E) shall submit a detailed testing
proposal specifying the method by which testing will be conducted and how
compliance will be demonstrated consistent with the applicable topcoat
protocol. The proposal shall include, at a minimum, a comprehensive plan
(including a rationale) for determining the transfer efficiency at each booth
through the use of in-plant or pilot testing, the selection of coatings to be
tested (for the purpose of determining transfer efficiency) including the
rationale for coating groupings, the method for determining the analytic VOM
content of as applied coatings and the formulation solvent content of as
applied coatings, and a description of the records of coating VOM content as
applied and coating's usage that will be kept to demonstrate compliance. Upon
approval of the proposal by the Agency and USEPA, the compliance demonstration
for a coating line may proceed.
c) Capture System Efficiency Test Protocols
1) Applicability
The requirements of subsection (c)(2) of this Section shall
apply to all VOM emitting process emission units employing capture equipment
(e.g., hoods, ducts), except those cases noted in this subsection
(c)(1).
A) If an emission unit is
equipped with (or uses) a permanent total enclosure (PTE) that meets Agency and
USEPA specifications, and which directs all VOM to a control device, then the
emission unit is exempted from the requirements described in subsection (c)(2)
of this Section. The Agency and USEPA specifications to determine whether a
structure is considered a PTE are given in Method 204 of appendix M of 40 CFR
51, incorporated by reference in Section 218.112 of this Part. In this
instance, the capture efficiency is assumed to be 100 percent and the emission
unit is still required to measure control efficiency using appropriate test
methods as specified in subsection (d) of this Section.
B) If an emission unit is equipped with (or
uses) a control device designed to collect and recover VOM (e.g., carbon
adsorber), an explicit measurement of capture efficiency is not necessary
provided that the conditions given below are met. The overall control of the
system can be determined by directly comparing the input liquid VOM to the
recovered liquid VOM. The general procedure for use in this situation is given
in
40 CFR
60.433, incorporated by reference in Section
218.112 of this Part, with the following additional restrictions:
i) Unless otherwise specified in subsection
(c)(1)(B)(ii), the owner or operator shall obtain data each operating day for
the solvent usage and solvent recovery to permit the determination of the
solvent recovery efficiency of the system each operating day using a 7-day
rolling period. The recovery efficiency for each operating day is computed as
the ratio of the total recovered solvent for that day and the most recent prior
6 operating days to the total solvent usage for the same 7-day period used for
the recovered solvent, rather than a 30-day weighted average as given in
40 CFR
60.433 incorporated by reference at Section
218.112 of this Part. This ratio shall be expressed as a percentage. The ratio
shall be computed within 72 hours following each 7-day period. A source that
believes that the 7-day rolling period is not appropriate may use an alterative
multi-day rolling period not to exceed 30 days, with the approval of the Agency
and USEPA. In addition, the criteria in subsection (c)(1)(B)(iii) or subsection
(c)(1)(B)(iv) must be met.
ii) The
owner or operator of the source engaged in printing located at 350 E.
22nd Street, Chicago, Illinois, shall obtain data
each operating day for the solvent usage and solvent recovery to permit the
determination of the solvent recovery efficiency of the system each operating
day using a 14-day rolling period. The recovery efficiency for each operating
day is computed as the ratio of the total recovered solvent for that day and
the most recent prior 13 operating days to the total solvent usage for the same
14-day period used for the recovered solvent, rather than a 30-day weighted
average as given in
40 CFR
60.433, incorporated by reference in Section
218.112 of this Part. This ratio shall be expressed as a percentage. The ratio
shall be computed within 17 days following each 14-day period. In addition, the
criteria in subsection (c)(1)(B)(iii) or subsection (c)(1)(B)(iv) must be
met.
iii) The solvent recovery
system (i.e., capture and control system) must be dedicated to a single coating
line, printing line, or other discrete activity that by itself is subject to an
applicable VOM emission standard, or
iv) If the solvent recovery system controls
more than one coating line, printing line or other discrete activity that by
itself is subject to an applicable VOM emission standard, the overall control
(i.e., the total recovered VOM divided by the sum of liquid VOM input from all
lines and other activities venting to the control system) must meet or exceed
the most stringent standard applicable to any line or other discrete activity
venting to the control system.
2) Capture Efficiency Protocols
The capture efficiency of an emission unit shall be measured
using one of the protocols given below. Appropriate test methods to be utilized
in each of the capture efficiency protocols are described in appendix M of 40
CFR 51, incorporated by reference at Section 218.112 of this Part. Any error
margin associated with a test method or protocol may not be incorporated into
the results of a capture efficiency test. If these techniques are not suitable
for a particular process, then an alternative capture efficiency protocol may
be used, pursuant to the provisions of Section 218.108(b) of this Part.
A) Gas/gas method using temporary total
enclosure (TTE). The Agency and USEPA specifications to determine whether a
temporary enclosure is considered a TTE are given in Method 204 of appendix M
of 40 CFR 51, incorporated by reference in Section 218.112 of this Part. The
capture efficiency equation to be used for this protocol is:
Image
where:
CE
|
=
|
Capture efficiency, decimal fraction;
|
Gw
|
=
|
Mass of VOM captured and delivered to control device
using a TTE;
|
Fw
|
=
|
Mass of uncaptured VOM that escapes from a
TTE.
|

incorporated by reference in Section 218.112 of this Part, is used to obtain
Gw. Method 204D in appendix M of 40 CFR 51, incorporated
by reference in Section 218.112 of this Part, is used to obtain
Fw.
B) Liquid/gas method using TTE. The Agency
and USEPA specifications to determine whether a temporary enclosure is
considered a TTE are given in Method 204 of appendix M of 40 CFR 51,
incorporated by reference in Section 218.112 of this Part. The capture
efficiency equation to be used for this protocol is:

=
|
Capture efficiency, decimal fraction;
|
L
|
=
|
Mass of liquid VOM input to process emission
unit;
|
Fw
|
=
|

TTE.
|
Method 204A or 204F contained in appendix M of 40 CFR 51,
incorporated by reference in Section 218.112 of this Part, is used to obtain L.
Method 204 D in appendix M of 40 CFR 51, incorporated by reference in Section
218.112 of this Part, is used to obtain Fw.
C) Gas/gas method using the
building or room (building or room enclosure), in which the affected coating
line, printing line or other emission unit is located, as the enclosure as
determined by Method 204 of appendix M of 40 CFR 51, incorporated by reference
in Section 218.112 of this Part, and in which "FB" and
"G" are measured while operating only the affected line or emission unit. All
fans and blowers in the building or room must be operated as they would under
normal production. The capture efficiency equation to be used for this protocol
is:
Image
where:
CE
|
=
|
Capture efficiency, decimal fraction;
|
G
|
=
|
Mass of VOM captured and delivered to control
device;
|
FB
|
=
|
Mass of uncaptured VOM that escapes from building
enclosure.
|
Method 204B or 204C contained in appendix M of 40 CFR 51,
incorporated by reference in Section 218.112 of this Part is used to obtain G.
Method 204E in appendix M of 40 CFR 51, incorporated by reference in Section
218.112 of this Part is used to obtain FB.
D) Liquid/gas method using the
building or room (building or room enclosure), in which the affected coating
line, printing line or other emission unit is located, as the enclosure as
determined by Method 204 of appendix M of 40 CFR 51, incorporated by reference
in Section 218.112 of this Part, and in which "FB" and
"L" are measured while operating only the affected line or emission unit. All
fans and blowers in the building or room must be operated as they would under
normal production. The capture efficiency equation to be used for this protocol
is:
Image
where:
CE
|
=
|
Capture efficiency, decimal fraction;
|
L
|
=
|
Mass of liquid VOM input to process emission
unit;
|
FB
|
=
|
Mass of uncaptured VOM that escapes from building
enclosure.
|
Method 204A or 204F contained in appendix M of 40 CFR 51,
incorporated by reference in Section 218.112 of this Part is used to obtain L.
Method 204E in appendix M of 40 CFR 51, incorporated by reference in Section
218.112 of this Part is used to obtain FB.
E) Mass balance using Data Quality
Objective (DQO) or Lower Confidence Limit (LCL) protocol. For a liquid/gas
input where an owner or operator is using the DQO/LCL protocol and not using an
enclosure as described in Method 204 of appendix M of 40 CFR 51, incorporated
by reference in Section 218.112 of this Part, the VOM content of the liquid
input (L) must be determined using Method 204A or 204F in appendix M of 40 CFR
51, incorporated by reference in Section 218.112 of this Part. The VOM content
of the captured gas stream (G) to the control device must be determined using
Method 204B or 204C in appendix M of 40 CFR 51, incorporated by reference in
Section 218.112 of this Part. The results of capture efficiency calculations
(G/L) must satisfy the DQO or LCL statistical analysis protocol as described in
Section 3 of USEPA's "Guidelines for Determining Capture Efficiency,"
incorporated by reference at Section 218.112 of this Part. Where capture
efficiency testing is done to determine emission reductions for the purpose of
establishing emission credits for offsets, shutdowns, and trading, the LCL
protocol cannot be used for these applications. In enforcement cases, the LCL
protocol cannot confirm non-compliance; capture efficiency must be determined
using a protocol under subsection (c)(2)(A), (B), (C) or (D) of this Section,
the DQO protocol of this subsection (c)(2)(E), or an alternative protocol
pursuant to Section 218.108(b) of this Part.
BOARD NOTE: Where LCL was used in testing emission units that
are the subject of later requests for establishing emission credits for
offsets, shutdowns, and trading, prior LCL results may not be relied upon to
determine the appropriate amount of credits. Instead, to establish the
appropriate amount of credits, additional testing may be required that would
satisfy the protocol of Section 218.105(c)(2)(A), (B), (C) or (D), the DQO
protocol of Section 218.105(c)(2)(E), or an alternative protocol pursuant to
Section 218.108(b) of this Part.
3) Simultaneous testing of multiple lines or
emission units with a common control device. If an owner or operator has
multiple lines sharing a common control device, the capture efficiency of the
lines may be tested simultaneously, subject to the following provisions:
A) Multiple line testing must meet the
criteria of Section 4 of USEPA's "Guidelines for Determining Capture
Efficiency, " incorporated by reference at Section 218.112 of this
Part;
B) The most stringent capture
efficiency required for any individual line or unit must be met by the
aggregate of lines or units; and
C)
Testing of all the lines of emission units must be performed with the same
capture efficiency test protocol.
4) Recordkeeping and Reporting
A) All owners or operators affected by this
subsection must maintain a copy of the capture efficiency protocol submitted to
the Agency and the USEPA on file. All results of the appropriate test methods
and capture efficiency protocols must be reported to the Agency within 60 days
after the test date. A copy of the results must be kept on file with the source
for a period of 3 years.
B) If any
changes are made to capture or control equipment, then the source is required
to notify the Agency and the USEPA of these changes and a new test may be
required by the Agency or the USEPA.
C) The source must notify the Agency 30 days
prior to performing any capture efficiency or control test. At that time, the
source must notify the Agency which capture efficiency protocol and control
device test methods will be used. Notification of the actual date and expected
time of testing must be submitted a minimum of 5 working days prior to the
actual date of the test. The Agency may at its discretion accept notification
with shorter advance notice provided that such arrangements do not interfere
with the Agency's ability to review the protocol or observe testing.
D) Sources utilizing a PTE must demonstrate
that this enclosure meets the requirements given in Method 204 in appendix M of
40 CFR 51, incorporated by reference in Section 218.112 of this Part, for a PTE
during any testing of their control device.
E) Sources utilizing a TTE must demonstrate
that their TTE meets the requirements given in Method 204 in appendix M of 40
CFR 51, incorporated by reference in Section 218.112 of this Part, for a TTE
during testing of their control device. The source must also provide
documentation that the quality assurance criteria for a TTE have been
achieved.
F) Any source utilizing
the DQO or LCL protocol must submit the following information to the Agency
with each test report:
i) A copy of all test
methods, Quality Assurance/Quality Control procedures, and calibration
procedures to be used from those described in appendix M of 40 CFR 51,
incorporated by reference in Section 218.112 of this Part;
ii) A table with information on each sample
taken, including the sample identification and the VOM content of the
sample;
iii) The quantity of
material used for each test run;
iv) The quantity of captured VOM for each
test run;
v) The capture efficiency
calculations and results for each test run;
vi) The DQO and/or LCL calculations and
results; and
vii) The Quality
Assurance/Quality Control results, including how often the instruments were
calibrated, the calibration results, and the calibration gases used.
d) Control

The control device efficiency shall be determined by simultaneously measuring
the inlet and outlet gas phase VOM concentrations and gas volumetric flow rates
in accordance with the gas phase test methods specified in subsection (f) of
this Section.
2) An owner or
operator:
A) That uses an afterburner or
carbon adsorber to comply with any Section of Part 218 shall use Agency and
USEPA approved continuous monitoring equipment which is installed, calibrated,
maintained, and operated according to vendor specifications at all times the
control device is in use except as provided in subsection (d)(3) of this
Section. The continuous monitoring equipment must monitor the following
parameters:
i) For each afterburner which
does not have a catalyst bed, the combustion chamber temperature of each
afterburner.
ii) For each
afterburner which has a catalyst bed, commonly known as a catalytic
afterburner, the temperature rise across each catalytic afterburner bed or VOM
concentration of exhaust.
iii) For
each carbon adsorber, the VOM concentration of each carbon adsorption bed
exhaust or the exhaust of the bed next in sequence to be desorbed.
B) Must install, calibrate,
operate and maintain, in accordance with manufacturer's specifications, a
continuous recorder on the temperature monitoring device, such as a strip
chart, recorder or computer, having an accuracy of ± 1 percent of the
temperature measured in degrees Celsius or ±
0.5o C, whichever is greater.
C) Of an automobile or light-duty truck
primer surfacer operation or topcoat operation subject to subsection (d)(2)(A),
shall keep a separate record of the following data for the control devices,
unless alternative provisions are set forth in a permit pursuant to Title V of
the Clean Air Act:
i) For thermal afterburners
for which combustion chamber temperature is monitored, all 3-hour periods of
operation in which the average combustion temperature was more than 28°C
(50°F) below the average combustion temperature measured during the most
recent performance test that demonstrated that the operation was in
compliance.
ii) For catalytic
afterburners for which temperature rise is monitored, all 3-hour periods of
operation in which the average gas temperature before the catalyst bed is more
than 28°C (50°F) below the average gas temperature immediately before
the catalyst bed measured during the most recent performance test that
demonstrated that the operation was in compliance.
iii) For catalytic afterburners and carbon
adsorbers for which VOM concentration is monitored, all 3-hour periods of
operation during which the average VOM concentration or the reading of organics
in the exhaust gases is more than 20 percent greater than the average exhaust
gas concentration or reading measured by the organic monitoring device during
the most recent determination of the recovery efficiency of a carbon adsorber
or performance test for a catalytic afterburner, which determination or test
demonstrated that the operation was in compliance.
3) An owner or operator that uses
a carbon adsorber to comply with Section 218.401 of this Part may operate the
adsorber during periods of monitoring equipment malfunction, provided that:
A) The owner or operator notifies in writing
the Agency within, 10 days after the conclusion of any 72 hour period during
which the adsorber is operated and the associated monitoring equipment is not
operational, of such monitoring equipment failure and provides the duration of
the malfunction, a description of the repairs made to the equipment, and the
total to date of all hours in the calendar year during which the adsorber was
operated and the associated monitoring equipment was not operational;
B) During such period of malfunction the
adsorber is operated using timed sequences as the basis for periodic
regeneration of the adsorber;
C)
The period of such adsorber operation does not exceed 360 hours in any calendar
year without the approval of the Agency and USEPA; and
D) The total of all hours in the calendar
year during which the adsorber was operated and the associated monitoring
equipment was not operational shall be reported, in writing, to the Agency and
USEPA by January 31 of the following calendar year.
e) Overall Efficiency
1) The overall efficiency of the emission
control system shall be determined as the product of the capture system
efficiency and the control device efficiency or by the liquid/liquid test
protocol as specified in
40 CFR
60.433, incorporated by reference in Section
218.112 of this Part, (and revised by subsection (c)(1)(B) of this Section) for
each solvent recovery system. In those cases in which the overall efficiency is
being determined for an entire line, the capture efficiency used to calculate
the product of the capture and control efficiency is the total capture
efficiency over the entire line.
2)
For coating lines which are both chosen by the owner or operator to comply with
Section 218.207(c), (d), (e), (f), (g), (m), or (n) of this Part by the
alternative in Section 218.207(b)(2) of this Part and meet the criteria
allowing them to comply with Section 218.207 of this Part instead of Section
218.204 of this Part, the overall efficiency of the capture system and control
device, as determined by the test methods and procedures specified in
subsections (c), (d) and (e)(1) of this Section, shall be no less than the
equivalent overall efficiency which shall be calculated by the following
equation:
Image
where:
E
|
=
|
Equivalent overall efficiency of the capture system
and control device as a percentage;
|
VOMa
|
=
|
Actual VOM content of a coating, or the
daily-weighted average VOM content of two or more coatings (if more than one
coating is used), as applied to the subject coating line as determined by the
applicable test methods and procedures specified in subsection (a) of this
Section in units of kg VOM/1 (lb VOM/gal) of coating solids as applied;
|
VOMl
|
=
|
The VOM emission limit specified in Section 218.204
or 218.205 of this Part in units of kg VOM/l (lb VOM/gal) of coating solids as
applied.
|
f) Volatile Organic Material Gas Phase Source
Test Methods.
The methods in 40 CFR 60, appendix A, incorporated by
reference in Section 218.112 of this Part delineated below shall be used to
determine control device efficiencies.
1)40 CFR 60, appendix A, Method 18, 25 or
25A, incorporated by reference in Section 218.112 of this Part as appropriate
to the conditions at the site, shall be used to determine VOM concentration.
Method selection shall be based on consideration of the diversity of organic
species present and their total concentration and on consideration of the
potential presence of interfering gases. Except as indicated in subsections
(f)(1)(A) and (B) below, the test shall consist of three separate runs, each
lasting a minimum of 60 minutes, unless the Agency and the USEPA determine that
process variables dictate shorter sampling times.
A) When the method is to be used to determine
the efficiency of a carbon adsorption system with a common exhaust stack for
all the individual adsorber vessels, the test shall consist of three separate
runs, each coinciding with one or more complete sequences through the
adsorption cycles of all the individual absorber vessels.
B) When the method is to be used to determine
the efficiency of a carbon adsorption system with individual exhaust stacks for
each absorber vessel, each adsorber vessel shall be tested individually. The
test for each absorber vessel shall consist of three separate runs. Each run
shall coincide with one or more complete adsorption cycles.
2)40 CFR 60, appendix A, Method 1
or 1A, incorporated by reference in Section 218.112 of this Part, shall be used
for sample and velocity traverses.
3)40 CFR 60, appendix A, Method 2, 2A, 2C or
2D, incorporated by reference in Section 218.112 of this Part, shall be used
for velocity and volumetric flow rates.

by case basis. An owner or operator must submit sufficient documentation for
the Agency and the USEPA to find that the test methods specified in subsections
(f)(1), (2), (3), (4), (5) and (6) of this Section will yield inaccurate
results and that the proposed adaptation is appropriate.
g) Leak Detection Methods for Volatile
Organic Material
Owners or operators required by this Part to carry out a leak
detection monitoring program shall comply with the following
requirements:
1) Leak Detection
Monitoring
A) Monitoring shall comply with 40
CFR 60, appendix A, Method 21, incorporated by reference in Section 218.112 of
this Part.
B) The detection
instrument shall meet the performance criteria of Method 21.
C) The instrument shall be calibrated before
use on each day of its use by the methods specified in Method 21.
D) Calibration gases shall be:
i) Zero air (less than 10 ppm of hydrocarbon
in air); and
ii) A mixture of
methane or n-hexane and air at a concentration of approximately, but no less
than, 10,000 ppm methane or n-hexane.
E) The instrument probe shall be traversed
around all potential leak interfaces as close to the interface as possible as
described in Method 21.
2) When equipment is tested for compliance
with no detectable emissions as required, the test shall comply with the
following requirements:
A) The requirements
of subsections (g)(1)(A) through (g)(1)(E) of this Section shall
apply.
B) The background level
shall be determined as set forth in Method 21.
3) Leak detection tests shall be performed
consistent with:
A) "APTI Course SI 417
controlling Volatile Organic Compound Emissions from Leaking Process
Equipment", EPA-450/2-82-015, incorporated by reference in Section 218.112 of
this Part.
B) "Portable Instrument
User's Manual for Monitoring VOC Sources", EPA-340/1-86-015, incorporated by
reference in Section 218.112 of this Part.
C) "Protocols for Generating Unit-Specific
Emission Estimates for Equipment Leaks of VOC and VHAP", EPA-450/3-88-010,
incorporated by reference in Section 218.112 of this Part.
D) "Petroleum Refinery Enforcement Manual",
EPA-340/1-80-008, incorporated by reference in Section 218.112 of this
Part.
h) Bulk
Gasoline Delivery System Test Protocol
1) The
method for determining the emissions of gasoline from a vapor recovery system
are delineated in 40 CFR 60, Subpart XX, section 60.503, incorporated by
reference in Section 218.112 of this Part.
2) Other tests shall be performed consistent
with:
A) "Inspection Manual for Control of
Volatile Organic Emissions from Gasoline Marketing Operations: Appendix D",
EPA-340/1-80-012, incorporated by reference in Section 218.112 of this
Part.
B) "Control of Hydrocarbons
from Tank Truck Gasoline Loading Terminals: Appendix A", EPA-450/2-77-026,
incorporated by reference in Section 218.112 of this Part.
i) Notwithstanding other
requirements of this Part, upon request of the Agency where it is necessary to
demonstrate compliance, an owner or operator of an emission unit which is
subject to this Part shall, at his own expense, conduct tests in accordance
with the applicable test methods and procedures specific in this Part. Nothing
in this Section shall limit the authority of the USEPA pursuant to the Clean
Air Act, as amended, to require testing.
j) Stage II Gasoline Vapor Recovery Test
Methods
The methods for determining the acceptable performance of
Stage II Gasoline Vapor Recovery System are delineated in "Technical
Guidance-Stage II Vapor Recovery Systems for Control of Vehicle Refueling
Emissions at Gasoline Dispensing Facilities," found at EPA 450/3-91-022b and
incorporated by reference in Section 218.112 of this Part. Specifically, the
test methods are as follows:
1)
Dynamic Backpressure Test is a test procedure used to determine the pressure
drop (flow resistance) through balance vapor collection and control systems
(including nozzles, vapor hoses, swivels, dispenser piping and underground
piping) at prescribed flow rates.
2) Pressure Decay/Leak Test is a test
procedure used to quantify the vapor tightness of a vapor collection and
control system installed at gasoline dispensing facilities.
3) Liquid Blockage Test is a test procedure
used to detect low points in any vapor collection and control system where
condensate may accumulate.
