A. The permittee shall not cause or allow to be discharged into the atmosphere from any covered emissions units any visible emissions in excess of the limits specified in subdivisions 1, 2 and 3 of this subsection.

1. Equipment manufactured or fabricated on or prior to August 31, 1983, shall not exceed an opacity of 20% when averaged over a six-minute period.

2. Equipment manufactured or fabricated after August 31, 1983, shall comply with 40 CFR Part 60, Subpart 000, 9VAC5-50-260 and the following standards:

a. Crushing: primary and secondary—15% opacity, tertiary—7% opacity.

b. Screening, conveyor transfers, and surge bins—10% opacity.

c. Fabric filter exhausts—7% opacity.

d. Wash plants—no visible emissions from wet screening and subsequent processing up to next crusher or storage bin.

3. Other nonspecific emission points including loadout and stationary diesel engines are limited to 10% opacity.

4. The opacity standards prescribed under this subsection shall apply at all times except during periods of startup, shutdown, malfunction, and as otherwise provided in the applicable standard. This subdivision shall apply only to (i) emission units, the construction, modification or relocation of which commenced on or after March 17, 1972; and (ii) emission units, the reconstruction of which commenced on or after December 10, 1976.

B. The permittee shall not cause or allow to be discharged into the atmosphere from any covered emissions units any particulate matter in excess of the limits specified in subdivisions 1 and 2 of this subsection.

1. Fabric filter exhausts controlling equipment manufactured or fabricated on or prior to August 31, 1983, shall not exceed the following limits:

a. For facilities located in AQCR 7, the limits in Table 510A (ref: 9VAC5-40-270).

b. For facilities located in the remainder of the Commonwealth, 0.05 grains/dscf (ref: Article 14 (9VAC5-40-1820 et seq.) of 9VAC5 Chapter 40).

2. Fabric filter exhausts controlling equipment manufactured or fabricated after August 31, 1983, shall not exceed 0.05 g/dscm (0.022 grains/dscf) (ref: 40 CFR Part 60, Subpart 000).

C. Fugitive dust/emissions controls shall include the following or equivalent as a minimum:

1. Fugitive dust/emissions from drills, stockpiles, material handling, screens, crushers, load-outs, and traffic areas shall be controlled by wet suppression or equivalent.

2. All material being stockpiled subject to windblown emissions shall be kept moist to control dust during storage and handling or covered at all times to minimize emissions.

3. Haul roads shall be controlled by wet suppression or equivalent.

4. Reasonable precautions shall be taken to prevent deposition of dirt on public roads and subsequent dust emissions. Materials spilled or tracked onto public paved surfaces shall be promptly removed to prevent particulate matter from becoming airborne.

D. In order to operate under the authority of this permit, a nonmetallic mineral processing facility shall not exceed any of the following:

1. The total rated crushing capacity for all primary crushers at the facility, including portable stone processing equipment temporarily located at the site, shall not exceed 5,000 tons per hour.

2. The total amount of fuel to be consumed by all stationary diesel engines, including portable equipment temporarily located at the site, shall not exceed 331,022 gallons of fuel per annual period.

3. The total actual emissions of any regulated pollutant from the stationary source shall not exceed 99 tons per annual period. Particulate matter emissions shall be used to determine compliance with this subdivision only if particulate matter (PM10) emissions cannot be quantified in a manner acceptable to the department.

E. The fuel used in stationary diesel engines shall be distillate oil or diesel fuel meeting ASTM specifications for No. 1 or No. 2 distillate oil or diesel fuel.
