NR 440.642(4)(k)3.3. Any change in the materials used for the following components is presumed to affect emissions: NR 440.642(4)(k)4.4. A change in the make, model, or composition of a catalyst is presumed to affect emissions, unless the change has been approved in advance by the administrator, based on test data that demonstrate that the replacement catalyst is equivalent to or better than the original catalyst in terms of particulate emission reduction. NR 440.642(4)(L)1.1. The administrator may revoke certification if he or she determines that the wood heaters being produced in that model line do not comply with the requirements of this section or sub. (3). Such a determination shall be based on all available evidence, including: NR 440.642(4)(L)1.a.a. Test data from a retesting of the original unit on which the certification test was conducted, NR 440.642(4)(L)1.b.b. A finding that the certification test was not valid. The finding shall be based on problems or irregularities with the certification test or its documentation, but may be supplemented by other information. NR 440.642(4)(L)1.c.c. A finding that the labeling of the wood heater does not comply with the requirements of par. (f), NR 440.642(4)(L)1.d.d. Failure by the manufacturer to comply with reporting and recordkeeping requirements under sub. (8), NR 440.642(4)(L)1.e.e. Physical examination showing that a significant percentage of production units inspected are not similar in all material respects to the representative affected facility submitted for testing, or NR 440.642(4)(L)1.f.f. Failure of the manufacturer to conduct a quality assurance program in conformity with par. (o). NR 440.642(4)(L)2.2. Revocation of certification under this paragraph may not take effect until the manufacturer concerned has been given written notice by the administrator setting forth the basis for the proposed determination and an opportunity to request a hearing under sub. (10). NR 440.642(4)(L)3.3. Determination to revoke certification based upon audit testing shall be made only in accordance with par. (p). NR 440.642(4)(m)(m) A catalytic wood heater shall be equipped with a permanent provision to accommodate a commercially available temperature sensor which can monitor combustor gas stream temperatures within or immediately downstream, i.e. within 2.54 centimeters (1 inch), of the combustor surface. NR 440.642(4)(n)(n) Any manufacturer of an affected facility subject under sub. (1) (b) to the applicable emission limits of this section that does not belong to a model line certified under this section shall cause that facility to be tested in an accredited laboratory in accordance with par. (f) 1., 2. and 4. before it leaves the manufacturer’s possession and shall report the results to the administrator. NR 440.642(4)(o)1.1. For each certified model line, the manufacturer shall conduct a quality assurance program which satisfies the following requirements: NR 440.642(4)(o)2.2. Except as provided in subd. 5., the manufacturer or authorized representative shall inspect at least one from every 150 units produced within a model line to determine that the wood heater is within applicable tolerances for all components that affect emissions as listed in par. (k) 2. NR 440.642(4)(o)3.a.a. Except as provided in subd. 3. c. or 5., the manufacturer or authorized representative shall conduct an emission test on a randomly selected affected facility produced within a model line certified under par. (e) on the following schedule: NR 440.642(4)(o)3.b.b. Emission tests shall be conducted in conformity with sub. (5) (a) using either approved method for measuring particulate matter as provided in sub. (5). The manufacturer shall notify the U.S. environmental protection agency by U.S. mail that an emissions test required pursuant to this paragraph will be conducted within one week of the mailing of the notification. NR 440.642(4)(o)3.c.c. If the manufacturer stated pursuant to par. (b) 3. that the firebox or any firebox component would be composed of a different material than the material used in the wood heater on which certification testing was performed, the first test shall be performed before 1,000 wood heaters are produced. The manufacturer shall submit a report of the results of this emission test to the administrator within 45 days of the completion of testing. NR 440.642(4)(o)4.4. The manufacturer shall take remedial measures, as appropriate, when inspection or testing pursuant to this paragraph indicates that affected facilities within the model line are not within applicable tolerances or do not comply with applicable emission limits. Manufacturers shall record the problem identified, the extent of the problem, the remedial measures taken, and the effect of such remedial measures as projected by the manufacturer or determined by any additional testing. NR 440.642(4)(o)5.a.a. If 2 consecutive passing tests are conducted under either subd. 2. or 3., the required frequency of testing under the applicable paragraph shall be modified as follows: Skip every other required test. NR 440.642(4)(o)5.b.b. If 5 consecutive passing tests are conducted under the modified schedule provided for in subd. 5. a., the required frequency of testing under the applicable paragraph shall be further modified as follows: Skip 3 consecutive required tests after each required test that is conducted. NR 440.642(4)(o)5.c.c. Testing shall resume on the frequency specified in subd. 2. or 3. as applicable, if a test failure results during any test conducted under a modified schedule.
