NR 440.688(6)(c)3.a.a. There are no individual readings greater than 10% opacity.
NR 440.688(6)(c)3.b.b. There are no more than 3 readings of 10% for the 1-hour period.
NR 440.688(6)(c)4.4. When determining compliance with the fugitive emissions standard for any crusher at which a capture system is not used as described under sub. (3) (c), the duration of the Method 9 observations may be reduced from 3 hours (30 6-minute averages) to one hour (10 6-minute averages) only if both of the following conditions apply:
NR 440.688(6)(c)4.a.a. There are no individual readings greater than 15% opacity.
NR 440.688(6)(c)4.b.b. There are no more than 3 readings of 15% for the 1-hour period.
NR 440.688(6)(d)(d) In determining compliance with sub. (3) (e), the owner or operator shall use Method 22 to determine fugitive emissions. The performance test shall be conducted while all affected facilities inside the building are operating. The performance test for each building shall be at least 75 minutes in duration, with each side of the building and the roof being observed for at least 15 minutes.
NR 440.688(6)(e)(e) The owner or operator may use the following as alternatives to the reference methods and procedures specified in this subsection:
NR 440.688(6)(e)1.1. For the method and procedure of par. (c), if emissions from 2 or more facilities continuously interfere so that the opacity of fugitive emissions from an individual affected facility cannot be read, either of the following procedures may be used:
NR 440.688(6)(e)1.a.a. Use for the combined emission stream the highest fugitive opacity standard applicable to any of the individual affected facilities contributing to the emission stream.
NR 440.688(6)(e)1.b.b. Separate the emissions so that the opacity of emissions from each affected facility can be read.
NR 440.688(6)(f)(f) To comply with sub. (7) (d), the owner or operator shall record the measurements as required in sub. (7) (c) using the monitoring devices in sub. (5) (a) and (b) during each particulate matter run and shall determine the averages.
NR 440.688(6)(g)(g) If, after 30 days notice for an initially scheduled performance test, there is a delay (due to operational problems, etc.) in conducting any rescheduled performance test, the owner or operator of an affected facility shall submit a notice to the department at least 7 days prior to any rescheduled performance test.
NR 440.688(6)(h)(h) Initial Method 9 performance tests under s. NR 440.11 and this subsection are not required for:
NR 440.688(6)(h)1.1. Wet screening operations and subsequent screening operations, bucket elevators and belt conveyors that process saturated material in the production line up to, but not including, the next crusher, grinding mill or storage bin.
NR 440.688(6)(h)2.2. Screening operations, bucket elevators and belt conveyors in the production line downstream of wet mining operations, that process saturated materials up to the first crusher, grinding mill or storage bin in the production line.
NR 440.688(7)(7)Reporting and recordkeeping.
NR 440.688(7)(a)(a) Each owner or operator seeking to comply with sub. (1) (d) shall submit to the department the following information about the existing facility being replaced and the replacement piece of equipment.
NR 440.688(7)(a)1.1. For a crusher, grinding mill, bucket elevator, bagging operation, or enclosed truck or railcar loading station, both of the following:
NR 440.688(7)(a)1.a.a. The rated capacity in megagrams or tons per hour of the existing facility being replaced,.
NR 440.688(7)(a)1.b.b. The rated capacity in megagrams or tons per hour of the replacement equipment.
NR 440.688(7)(a)2.2. For a screening operation:
NR 440.688(7)(a)2.a.a. The total surface area of the top screen of the existing screening operation being replaced, and
NR 440.688(7)(a)2.b.b. The total surface area of the top screen of the replacement screening operation.
NR 440.688(7)(a)3.3. For a conveyor belt:
NR 440.688(7)(a)3.a.a. The width of the existing belt being replaced and
NR 440.688(7)(a)3.b.b. The width of the replacement conveyor belt.
NR 440.688(7)(a)4.4. For a storage bin, both of the following:
NR 440.688(7)(a)4.a.a. The rated capacity in megagrams or tons of the existing storage bin being replaced.
NR 440.688(7)(a)4.b.b. The rated capacity in megagrams or tons of replacement storage bins.
