As required in Subpart AAA, section 60.354(d), you or your approved test laboratory must also
measure the first hour of particulate matter emissions for each test run using a separate filter in
one of the two parallel sampling trains. These results must be reported separately and also
included in the total particulate matter emissions per run. Also, as required by Subpart AAA,
section 60.534(e), you must have your approved laboratory measure the efficiency, heat output,
and carbon monoxide emissions of the tested wood heater using CSA-B415.1-10. For
measurement of particulate matter emission concentrations, ASTM 2515-11 must be used.
The following change to ASTM E3053-17 must be followed:
1. Coal bed conditions prior to loading test fuel. The coal bed shall be a level plane without
valleys or ridges for all test runs in the high, low, and medium burn rate categories.
The following changes to ASTM E2515-11 must be followed :
1. The filter temperature must be maintained between 80 and 90 degrees F during testing.
2. Filters must be weighed in pairs to reduce weighing error propagation; see ASTM 2515-
11 , Section 10.2.1 Analytical Procedure.
3. Sample filters must be Pall TX-40 or equivalent Teflon-coated glass fiber, and of 47 mm,
90 mm, 100 mm, or 110 mm in diameter.
4. Only one point is allowed outside the+/- 10 percent proportionality range per test run.
A copy of this letter must be included in each certification test report where this alternative test
method is utilized.
It
is reasonable that this alternative test method approval be broadly applicable to all wood
heaters subject to the requirements of 40 CFR part 60, Subpart AAA. For this reason, we will
post thi s letter as ALT-125 on our website at http://www3.epa.gov/ttn/emc/approalt.html for use
by other interested parties. As noted earlier in this letter, this alternative method approval is valid
until such time that Subpart AAA is revised or replaced to require a different cord wood
certification method, and at such time, this alternative will be reconsidered and possibly
withdrawn.
