NR 440.642(3)(b)2.2. An affected facility not equipped with a catalytic combustor may not discharge into the atmosphere any gases which contain particulate matter in excess of a weighted average of 7.5 g/hr (0.017 lb/hr). Particulate emissions may not exceed 15 g/hr (0.033 lb/hr) during any test run at a burn rate less than or equal to 1.5 kg/hr (3.3 lb/hr) that is required to be used in the weighted average, and particulate emissions may not exceed 18 g/hr (0.040 lb/hr) during any test burn at a burn rate greater than 1.5 kg/hr (3.3 lb/hr) that is required to be used in the weighted average.

NR 440.642(4)(a)(a) For each model line, compliance with applicable emission limits may be determined based on testing of representative affected facilities within the model line.

NR 440.642(4)(b)(b) Any manufacturer of an affected facility may apply to the administrator for a certificate of compliance for a model line. The application shall be in writing to: Stationary Source Compliance Division (EN-341), U.S. Environmental Protection Agency, 401 M Street SW, Washington DC 20460, Attention: Wood Heater Program. The manufacturer shall submit 2 complete copies of the application and attachments. The application shall be signed by the manufacturer, or an authorized representative, and shall contain the following:

NR 440.642(4)(b)3.a.a. Engineering drawings and specifications of components that may affect emissions, including specifications for each component listed in par. (k). Manufacturers may use complete assembly or design drawings that have been prepared for other purposes, but should designate on the drawings the dimensions of each component listed in par. (k). Manufacturers shall identify tolerances of components of the tested unit listed in par. (k) 2. that are different from those specified in that paragraph, and show that such tolerances may not reasonably be anticipated to cause wood heaters in the model line to exceed the applicable emission limits.

NR 440.642(4)(b)3.b.b. A statement whether the firebox or any firebox component (other than one listed in par. (k) 3.) will be composed of different material from the material used for the firebox or firebox component in the wood heater on which certification testing was performed and a description of any such differences.

NR 440.642(4)(b)3.c.c. For applications to certify a model line of catalytic wood heaters to meet the emission limits in sub. (3) (b), a statement describing the manufacturer’s program to ensure consistency in the size of any gap in the catalyst bypass mechanism. The statement shall describe, in narrative form, the components of the system that affect the size of the gap, any specifications for critical dimensions of any such components, and the procedure the manufacturer will use to ensure consistency in the size of the catalyst bypass gap.

NR 440.642(4)(b)4.4. All documentation pertaining to a valid certification test, including the complete test report and, for all test runs: raw data sheets, laboratory technician notes, calculations, and test results. Documentation shall include the items specified in the applicable test methods. Recommended formats and guidance materials are available from the administrator.

NR 440.642(4)(b)6.6. A statement that the manufacturer will conduct a quality assurance program for the model line which satisfies the requirements of par. (o).

NR 440.642(4)(b)7.7. A statement describing how the tested unit was sealed by the laboratory after the completion of certification testing, and

NR 440.642(4)(b)8.8. A statement that the manufacturer will notify the accredited laboratory if the application for certification is granted, within 30 days of receipt of notification from the U.S. environmental protection agency.

NR 440.642(4)(b)9.a.a. Similar in all material respects to the wood heater submitted for certification testing, and

NR 440.642(4)(b)9.b.b. Will be labeled as prescribed in sub. (7).

NR 440.642(4)(b)10.10. For catalytic wood heaters, a statement that the warranty, access and inspection, and temperature monitoring provisions in pars. (c), (d), and (m) will be met.

NR 440.642(4)(b)12.12. A written estimate of the number of wood heaters that the manufacturer anticipates will be produced annually for the first 2 production years. Compliance with this provision may be obtained by designating one of the following ranges:
