NR 415.075 NR 415.075 Particulate matter emission limitations for ledge rock quarries and industrial sand mines.

NR 415.075(1) (1) Applicability.

NR 415.075(1)(a) (a) Except as provided in par. (b), the provisions of this section are applicable to the following operations and emission points in ledge rock quarries and industrial sand mines: blasting, drilling, roads, storage piles and use of haul trucks.

NR 415.075(1)(b) (b) Operations at any of the following ledge rock quarries and industrial sand mines are not subject to the provisions of subs. (2) to (4):

NR 415.075(1)(b)1. 1. Ledge rock quarries with actual production of less than 25,000 tons per month on a rolling 12 month average.

NR 415.075(1)(b)2. 2. Ledge rock quarries with actual operation of less than 365 days per 5 year period.

NR 415.075(1)(b)3. 3. Industrial sand mines with actual production of less than 2,000 tons per month on a rolling 12 month average.

NR 415.075(1)(c) (c) When a ledge rock quarry or industrial sand mine is operated by more than one owner or operator, then actual production and actual operation shall be cumulative at the site. The applicable particulate emissions limitations of this section shall be applicable to all subsequent operators or owners at that site.

NR 415.075(2) (2) Particulate emission limitations in all areas of the state.

NR 415.075(2)(a) (a) No person may cause, allow or permit the use of any parking lot, road or other area by haul trucks or any drilling or blasting without taking precautions to prevent particulate matter from becoming airborne. These precautions shall be taken to the extent necessary so that any applicable requirements are met and shall include one or more of the following:

NR 415.075(2)(a)1. 1. Application of asphalt, water or suitable chemicals on unpaved roads or other areas used by haul trucks which can create airborne dust, provided the application does not create a hydrocarbon, odor or water pollution problem.

NR 415.075(2)(a)2. 2. Posting and maintenance of a 10 MPH speed limit on paved or unpaved roads or other areas used by haul trucks inside the facility’s property line.

NR 415.075(2)(a)3. 3. Covering, treatment or securing of materials likely to become airborne from haul trucks during transport, prior to any transportation off site from the quarry or mine.

NR 415.075(2)(a)4. 4. Use of wet drilling or other means of control approved by the department.

NR 415.075(2)(a)5. 5. The use of blast hole stemming materials that have been approved by either the department or the department of safety and professional services.

NR 415.075(2)(a)6. 6. Any precautions proposed by the owner or operator and accepted by the department in a permit or fugitive dust control plan.

NR 415.075(2)(a)7. 7. Use of no precautions where control measures are unnecessary due to site or meteorological conditions.

NR 415.075(2)(b) (b) In addition to meeting the requirements of par. (a), the owner or operator shall control fugitive emissions from a road or other area used by haul trucks and from drilling so that visible emissions do not exceed 20% opacity at the source.

NR 415.075(2)(c) (c) The owner or operator shall submit to the department the fugitive dust control plan described in sub. (6).

NR 415.075(3) (3) Particulate emissions limitations for operations in specific geographic areas. In addition to meeting the limitations of sub. (2), the owner or operator of any ledge rock quarry or industrial sand mine located in an area identified in s. NR 415.035 (1) shall do all of the following:

NR 415.075(3)(a) (a) Prior to a haul truck’s departure from plant property, the haul truck’s wheels and tires shall be sprayed with water or otherwise cleaned at the exit point from plant property.

NR 415.075(3)(b) (b) Storage piles of material having a silt content of greater than 5% shall be treated with water, surfactants, stabilizers or chemicals; draped; or enclosed on a minimum of 3 sides. The height of enclosure shall ensure that excessive fugitive dust emissions are prevented. Access areas surrounding storage piles shall be watered, cleaned or treated with stabilizers as needed to prevent fugitive dust from vehicle traffic.
