TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 59--NATIONAL VOLATILE ORGANIC COMPOUND EMISSION STANDARDS FOR
CONSUMER AND COMMERCIAL PRODUCTS--Table of Contents
Subpart C--National Volatile Organic Compound Emission Standards for
Consumer Products
Sec. 59.208 Charcoal lighter material testing protocol.
(a) Each manufacturer or importer of charcoal lighter material
subject to this subpart shall demonstrate compliance with the applicable
requirements of Sec. 59.203(d) using the procedures specified in this
section. Any lighter material that has received certification from
California South Coast Air Quality Management District (SCAQMD) under
their Rule 1174, Ignition Method Compliance Certification Testing
Protocol, will be considered as having demonstrated compliance with the
applicable requirements of this subpart using the procedures in this
section.
(b) The manufacturer or importer shall obtain from the testing
laboratory conducting the testing, a report of findings, including all
raw data sheets/charts and laboratory analytical data. The testing must
demonstrate that VOC emissions resulting from the ignition of the
barbecue charcoal are, on average, less than or equal to 9 grams
[[Page 307]]
per start. The manufacturer or importer shall maintain the report of
findings.
(c) When a charcoal lighter material does not fall within the
testing guidelines of this protocol, the protocol may be modified
following a determination by the Administrator that the modified
protocol is an acceptable alternative to the method described in this
section and written approval of the Administrator.
(d) Meteorological and environmental criteria. (1) Testing shall be
conducted under the following conditions:
(i) Inlet combustion air temperature is 16 to 27 degrees Celsius (60
to 80 degrees Fahrenheit) with a relative humidity of 20 to 80 percent;
(ii) The charcoal and lighter material are stored 72 hours before
testing in a location with a relative humidity between 45 and 65
percent, and a temperature between 18 and 24 degrees Celsuis (65 to 75
degrees Fahrenheit); and
(iii) The outside wind speed, including gusts, may be no more than
16 kilometers per hour (10 miles per hour) if the test stack is
exhausted outdoors, or, if the test stack is exhausted indoors, indoor
air must be stagnant.
(2) Temperature and relative humidity of the combustion air shall be
continuously monitored during the test. Temperature and relative
humidity of the place where the charcoal and lighter material are stored
prior to the test shall be monitored and recorded during the 72 hours
immediately prior to the test. If the stack is exhausted outdoors, the
continuous outdoor wind speed monitor shall be observed or recorded
continuously during testing. If the wind speed monitor is manually
observed rather than electronically recorded, the maximum wind speed
observed during the test shall be recorded.
(e) Definitions. For the purposes of this test protocol, the
following definitions shall apply:
(1) Baseline VOC emissions (Eb) means the 3.6 grams
(0.008 pounds) per start of subject VOC mass emissions (calculated as
CH2) resulting from the ignition of charcoal by electric
probe.
(2) Emission limit for VOC means 9 grams per start of resultant VOC
emissions (Er), (expressed as CH2).
(3) Equivalent means equipment that has been demonstrated to meet or
exceed the performance, design, and operation specifications of the
prescribed equipment. A demonstration that equipment or a test method is
a suitable alternative requires written approval from the Administrator
prior to compliance testing, based on an evaluation of comparative
performance specifications and/or actual performance test data.
(4) Ignition means the ready-to-cook condition of the charcoal
determined by the temperature above the charcoal, the organic vapor
concentration measured by the continuous organic emission monitor, and
percent ash.
(5) Ignition VOC emissions (eI)--means the grams (pounds)
per start of total subject VOC mass emissions (expressed as
CH2) resulting from the ignition of charcoal by the lighter
material undergoing evaluation, including both charcoal and lighter
material emissions.
(6) labeled directions means those directions affixed to the
charcoal lighter material which specify:
(1) The amount of lighter material to use per kilogram (or pound) of
charcoal, unless the lighter material is already impregnated or treated
in the charcoal;
(2) How to use or apply the lighter material; and
(3) How and when to light the lighter material.
(7) Percent ash means a qualitative observation of the ratio of
visible charcoal surface area ignited (grayish/white ash) to total
charcoal surface area times 100.
(8) Reference VOC emissions (Eep)--means the grams
(pounds) per start of subject VOC mass emissions (calculated as
CH2) resulting from the ignition of charcoal by the reference
electric probe during the testing.
(9) Resultant VOC emissions (Er)--means the ignition VOC
emission (EI) less the reference VOC emissions
(Eep) plus baseline emissions (Eb).
(10) Start means a 25-minute period commencing from the instant that
emissions may be released from the lighter material, either by
evaporation or combustion, and further characterized such that by the
end of said 25-minute period, ignition is achieved.
[[Page 308]]
(f) Test structure, equipment specifications, and reference
materials. (1) The test structure is to be located in a building or

enclosure shall be such that there are no constant or intermittent air
flows within it that cause fluctuations in the stack velocity and/or
disruptions of air flow patterns within the test chamber containing the
reference grill . (WARNING: If the stack is vented into the building
enclosure, caution must be taken to avoid carbon monoxide poisoning and
the reduction of oxygen.)

(g) Sampling and analytical methods. (1) Gas volumetric flow rate.
Conduct a full velocity traverse using the stack velocity measurement
device as shown in figure 3 of this Appendix A to this Subpart, or use
Method 1A of 40 CFR part 60, appendix A. Continuously record a velocity
reference point reading during each test run using a chart recorder or
once every 20 seconds if using Method 1A. Calculate the volumetric flow
rate using the gas velocity, moisture content, and the stack cross-
sectional area. For the purposes of this protocol, the static pressure
shall be assumed to be atmospheric, the molar density correction factor
in the stack to be 1.0, and the moisture content to be 2 percent.
(2) Integrated VOC sample. Collect integrated VOC gas samples at the
sampling port in the exhaust stack using a 40 CFR part 60, appendix A,
Method 25 Total Combustion Analysis (TCA) sampling apparatus consisting
of two evacuated 9-liter tanks, each equipped with flow controllers,
vacuum gauges, and probes, as shown in figure 4 of Appendix A of this
Subpart. Use 40 CFR part 60, appendix A, Method 25, SCAQMD Method 25.1
(incorporated by reference--Sec. 59.213 of this subpart), or equivalent,
for analysis. Carbon monoxide, carbon dioxide, methane, and non-methane
organic carbon are analyzed by the TCA and TCA/Flame Ionization Detector
(FID) methods. Oxygen content is determined by gas chromatography using
a thermal conductivity detector. Clean particulate filters between use
by heating to 760 degrees Celsius (1400 degrees Fahrenheit) while using
compressed air as a carrier for cleaning and purging.
(3) Continuous organic emissions monitor. A continuous organic
emissions monitor which uses a continuous FID shall be used for each
test run to measure the real time organic concentration of the exhaust
as methane. Record the emission monitor response in parts per million
continuously during the sampling period using a chart
[[Page 310]]
recorder or at least once every 10 seconds. The VOC analyzer shall be
operated as prescribed in the manufacturer's directions unless otherwise
noted in this protocol.
(h) Pretest procedure. (1) Charcoal lighter material--charcoal.
Before each test run, remove charcoal from a sealed bag that has been
stored for at least 72 hours in a humidity and temperature controlled
room which satisfies the requirements of paragraph (d)(1) of this
section and weight out 0.9 kilograms (2 pounds) of charcoal briquettes,
to the nearest whole briquette over 0.9 kilograms (2 pounds), of uniform
shape with no broken pieces using an analytical balance. Reseal the bag.
Charcoal must be ignited within 10 minutes after removal from bag. A
sealed or resealed bag of charcoal cannot be stored at the test site for
greater than 45 minutes. It must be returned to a humidity and
temperature controlled room from 72 hours. The lighter material must be
purchased, stored, weighed, and handled the same as the barbecue
charcoal.
(i) For the reference VOC emission tests using an electric probe,
place a single layer of charcoal, slightly larger than the area/circle
of the electric probe heating element, onto the grate. Place the heating
element on top of this first layer and cover the heating element with
the remaining charcoal briquettes.
(ii) For the ignition VOC emissions tests, arrange the briquettes on
the barbecue grate in the manner specified by the ignition
manufacturer's directions. If these manufacturer's directions do not
specify a stacking arrangement for the briquettes, randomly stack the
briquettes in a pile using the stacking ring described in paragraph
(f)(3)(ix) of this section.
(2) Charcoal lighter material--or impregnated charcoal. Store,
handle, weigh, and stack barbecue charcoal that is designed to be lit
without the packaging, the same as in paragraph (h)(1) of this section.
For those products which require both the package and charcoal be lit,
weigh the whole package--do not remove charcoal. Weigh an empty package
(not the same one to be used during the test). Subtract the package
weight from the overall weight of the package and charcoal. The full
package and empty package must be stored, handled, and weighed the same
as in paragraph (h)(1) of this section. If the difference (the charcoal
weight) is between 0.7 to 1.4 kilograms (1.5 to 3.0 pounds), the test
may proceed. The emissions measured (E) in Equation 5 of paragraph
(k)(7) of this section must be adjusted to a 0.9 kilogram (2-pound)
charge. Place packaged barbecue charcoal on the grate in the manner
specified by the manufacturer's directions.
(3) Initial meteorological and environmental criteria in paragraph
(d) shall be complied with.
(4) The stack velocity must be set before each day of testing at 140
9 meters per minute (450 30 feet per minute)
by performing a velocity traverse as specified in paragraph (g)(1) of
this section. The velocity will be attained by adjusting the axial fan
speed using a rheostat.
(5) The fireplace shall be conditioned at the start of each day
before sampling tests by using a grill ignited by the electric probe. If
a time period of over 60 minutes between sampling test runs occur, the
condition step must be repeated.
(6) Before each test run, leak check the continuous organic
emissions monitor by blocking the flow to the probe. Allow the
instrument to warm up for the duration specified by the manufacturer's
directions. Select the 0 to 100 parts per million range. Check the
battery level and hydrogen pressure. Zero with hydrocarbon-free air
(<0.1 parts per million hydrocarbons as methane) span with 90 parts per
million methane in ultra pure air. Zero and span another instrument
selection range if needed for test purposes.
(7) Before the testing program begins, establish a point of average
concentration of organics in the stack by using a continuous organic
emissions monitor and a grill with charcoal ignited by the electric
probe 40 minutes after initial release of emissions. Record the
continuous organic emissions monitor traverse data.
(8) Prepare the integrated VOC sampling equipment and perform the
required leak checks. Fit the probes with nozzles housing two micron
particulate filters. Insert the probes and nozzles
[[Page 311]]
into the sampling port to draw a sample of the exhaust gas from the
point of average organic concentration as determined from the continuous
organic emissions monitor sample traverse described in paragraph (h)(4)
of this section. Also, position the nozzles such that they point
downstream in the stack. Obtain the samples concurrently and
continuously over the test run.
(9) Insert the continuous organic emissions monitor probe into the
sampling port to draw a sample of the exhaust gas from the point of
average organic concentration as determined from the continuous organic
emissions monitor sample traverse described in paragraph (h)(7) of this
section.
(i) Test procedure. The labeled directions, as defined in paragraph
(e) of this section, shall be followed throughout the course of the
testing. In cases where the directions are incompatible with this
protocol, circumvent the intent of this protocol, or are unclear
(subject to different interpretations) and inadequate, the Administrator
must be informed in writing of the nature of the conflict, as well as
the proposed resolution, prior to commencing testing. When the labeled
directions for a charcoal lighter material do not fall within the
testing guidelines of this protocol, the protocol may only be modified
upon written approval of the Administrator.
(1) Place the bottom of the barbecue grill on the floor of the
fireplace, 5 centimeters (2 inches) from the rear wall. Ignite charcoal
as specified by manufacturer's labeled directions.
(2) For electric probe ignition, carefully remove probe without
disturbing charcoal after 10 minutes of operation.
(3) For fluid ignition, simultaneously match light fluid on charcoal
and fluid that has fallen to the bottom of the grill.
(4) Place the grill temperature probe 11 centimeters (4.5 inches)
above the top of the charcoal immediately after the charcoal lighter
material flame goes out, or before, if the lighter material does not
flame.
(5) Conduct at least six test runs for both the electric probe
ignition and for the lighter material being evaluated. Alternate these
lighter material for all 12 runs. All runs must be conducted over 3
consecutive days or less. Alternatively, baseline emissions testing
(using the electric probe) may be applied to other test runs provided
the test runs occur within 4 months of the baseline testing. Integrated
VOC sampling and continuous organic emissions monitoring begin for each
test run when the charcoal lighter material and/or materials start to
generate/release organics (this will be the time of pouring for lighter
fluids and the time of ignition for most other ignition sources).
Option: Because the manufacturer of treated or impregnated charcoal
supplies both the lighter material and barbecue charcoal, they may apply
the 9 grams VOC per start emission limit as an absolute value without an
adjustment for the VOC emissions from an electric probe.
(6) Sampling ends for each test run when all the following
conditions are met:
(i) The temperature 11 centimeters (4.5 inches) above the maximum
height of the briquette pile, using the grill temperature probe
described in paragraph (d)(3)(ii) of this section, is at least 93
degrees Celsius (200 degrees Fahrenheit);
(ii) The continuous organic emissions monitor is reading below 30
parts per million for at least 2 minutes;
(iii) The test sampling has continued for 25 minutes (but not more)
and
(iv) The charcoal surface is 70 percent covered with ash (to be
documented with photograph on top and 60 degrees above the horizon).
(7) During the sampling test runs, temperatures (excluding ambient)
and continuous organic emission monitor readings shall be recorded and
shall comply with the requirements in paragraph (b) of this section.
Humidity, wind speed, and ambient temperature readings shall be
monitored and shall comply with the requirements in paragraph (b) of
this section.
(8) Collect one blank sample for VOC and one ambient air sample
during one run of each day per paragraph (k) of this section.
(j) Post-run procedure. (1) Record temperatures (including ambient),
humidity, wind speed, and continuous organic emissions monitor reading.
[[Page 312]]
(2) Record the drift using zero and span gases. Leak check and span
the continuous organic emissions monitor as described in paragraph
(h)(6) of this section for the next run.
(3) Leak check and disassemble the integrated VOC sampling equipment
as described in Method 25 of 40 CFR part 60, appendix A or SCAQMD Method
25.1 (incorporated by reference--see Sec. 59.213 of this subpart), or
equivalent.
(4) Thoroughly clean grill surfaces of all residue before conducting
next ignition run.
(k) Calculations. Calculations shall be carried out to at least one
significant digit beyond that of the acquired data, and then rounded off
after final calculation to two significant digits for each run. All
rounding off of numbers should be in accordance with the American
Society for Testing and Materials (ASTM) E 380-93, Standard Practice for
Use of the SI International System of Units, procedures (incorporated by
reference--see Sec. 59.213 of this subpart).
(1) Calculate the average stack reference point temperature during
