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.

The administrator may not select more than one model line under this program for every 5 model lines for which certification is granted under par. (e) to meet the emission limits in sub. (3) (b). No accredited laboratory may test or bear the expense of testing, as provided in the contract described in par. (g), more than one model line from every 5 model lines tested by the laboratory for which certification was granted. The administrator shall use a procedure that ensures that the selection process is random.
NR 440.642(4)(p)1.b. b. The administrator may, by means of a neutral selection scheme, select model lines certified under par. (b) or (e), for selective enforcement audit testing under this paragraph. Prior to July 1, 1990, the administrator shall only select a model line for a selective enforcement audit on the basis of information indicating that affected facilities within the model line may exceed the applicable emission limit in sub. (3).
NR 440.642(4)(p)2. 2. The administrator shall randomly select for audit testing 5 production wood heaters from each model line selected under this paragraph. These wood heaters shall be selected from completed units ready for shipment from the manufacturer's facility (whether or not the units are in a package or container). The wood heaters shall be sealed upon selection and remain sealed until they are tested or until the audit is completed. The wood heaters shall be numbered in the order that they were selected.
NR 440.642(4)(p)3.a.a. The administrator shall test, or direct the manufacturer to test, the first of the 5 wood heaters selected under subd. 2. in a laboratory accredited under sub. (6) that is selected pursuant to subd. 4.
NR 440.642(4)(p)3.b. b. The expense of the random compliance audit test shall be the responsibility of the wood heater manufacturer. A manufacturer may require the laboratory that performed the certification test to bear the expense of a random compliance audit test by means of the contract required under par. (g). If the laboratory with which the manufacturer had a contract has ceased business due to bankruptcy or is otherwise legally unable to honor the contract, the administrator may not select any of that manufacturer's model lines for which certification testing has been conducted by that laboratory for a random compliance audit test.
NR 440.642(4)(p)3.c. c. The test shall be conducted using the same test method and procedure used to obtain certification. If the certification test consisted of more than one particulate sampling test method, the administrator may use either one of these methods for the purpose of audit testing. If the test is performed in a pressure vessel, air pressure in the pressure vessel shall be maintained within 1% of the average of the barometric pressures recorded for each individual test run used to calculate the weighted average emission rate for the certification test. The administrator shall notify the manufacturer at least one week prior to any test under this paragraph, and allow the manufacturer or authorized representatives to observe the test.
NR 440.642(4)(p)4.a.a. Except as provided in this paragraph, the administrator may select any accredited laboratory for audit testing. The following contains a nesting potential redrafting situation
NR 440.642(4)(p)4.b. b. The administrator shall select the accredited laboratory that performed the test used to obtain certification for audit testing, until the administrator has amended this section to allow testing at another laboratory. If another laboratory is selected pursuant to this subdivision, and the overall precisions of the test method and procedure is greater than "1 gram per hour (± 0.0022 lb per hour) of the weighted average at laboratories below 304 meters (1,000 feet) elevation (or equivalent), the interlaboratory component of the precision shall be added to the applicable emissions standard for the purposes of this subdivision.
NR 440.642(4)(p)4.c. c. The administrator may not select an accredited laboratory that is located at an elevation more than 152 meters (500 feet) higher than the elevation of the laboratory which performed the test used to obtain certification, unless the audit test is performed in a pressure vessel.
NR 440.642(4)(p)5.a.a. If emissions from a wood heater tested under subd. 3. exceed the applicable weighted average emission limit by more than 50%, the administrator shall so notify the manufacturer that certification for that model line is suspended effective 72 hours from the receipt of the notice, unless the suspension notice is withdrawn by the administrator. The suspension shall remain in effect until withdrawn by the administrator, or 30 days from its effective date if a revocation notice under subd. 5. b. is not issued within that period, or the date of final agency action on revocation, whichever occurs earlier. The following contains a nested potential redrafting situation
NR 440.642(4)(p)5.b. b. 1) If emissions from a wood heater tested under subd. 3. exceed the applicable weighted average emission limit, the administrator shall notify the manufacturer that certification is revoked for that model line.
