The owner or operator of an affected facility shall thereafter conduct a performance test each month except as described under subd. 4. and pars. (g) and (j). Initial and monthly performance tests shall be conducted according to the procedures in this subsection.

NR 440.644(4)(b)3. 3. The owner or operator of an affected facility who seeks to comply with the equipment design and performance specifications, as described under par. (j), shall repeat the performance test when directed by the department or when the owner or operator elects to operate the capture system or control device at conditions different from the most recent determination of control device efficiency or measurement of capture system retention time or face velocity. The performance test shall be conducted in accordance with the procedures described under par. (f) 2. b.

In lieu of conducting a monthly performance test, the owner or operator of each tread end cementing operation and each green tire spraying operation shall submit formulation data or the results of Method 24 analysis annually to verify the VOC content of each tread end cement and each green tire spray material, provided the spraying formulation has not changed during the previous 12 months.
