The requirements in Sector D apply to stormwater discharges associated with industrial activity from asphalt paving and roofing materials and lubricant manufacturing facilities as identified by the industrial activity codes specified in Table 5 of Appendix D.
a. Manufacturing asphalt paving mixtures blocks and roofing materials.
b. Stationary and portable asphalt plant facilities.
c. Manufacturing lubricating oils and greases and miscellaneous products of petroleum and coal.
The following industrial stormwater discharges associated with industrial activity are not authorized by this permit:
a. Discharges from petroleum refining facilities, including those that manufacture asphalt or asphalt products that are classified as SIC Code 2911.
b. Discharges from oil recycling facilities.
c. Discharges associated with fats and oils rendering.
a. Employee Training (No additional requirements).
b. Erosion and Sedimentation Control (No additional requirements).
c. Good Housekeeping (No additional requirements).
1. The Permittee shall inspect the following areas: material storage and handling areas; liquid storage tanks, hoppers, and silos; vehicle and equipment maintenance, cleaning, and fueling areas; and material handling vehicles, equipment, and processing areas. Ensure that appropriate action is taken in response to the inspection by using follow-up procedures. Document in the SWPPP the inspections and follow up actions.
2. In addition to the inspection requirements outlined in Part III.G, the Permittee shall ensure that a total of two (2) of the required monthly inspections occur during runoff events, with at least one being performed during snow melt. Each inspection shall include a visual assessment of the runoff to identify any visible sheens or films that indicate the presence of oil or grease in the discharge. If sheens are present in stormwater discharges, corrective actions to prevent sheen shall be implemented and documented in the SWPPP.
The Permittee is only required to conduct visual inspections of runoff originating from, or passing through, areas of industrial activity and/or significant materials. Any runoff that does not contact industrial activity and/or significant materials (e.g. office buildings, employee parking lots, natural areas, etc) is not required to be inspected.
e. Preventive Maintenance (No additional requirements).
f. Spills and Leaks (No additional requirements).
g. Management of Runoff (No additional requirements).
h. Other Industry Specific Control Measures (No additional requirements).
Sector-Specific Benchmark Values and Effluent Limitations: Sector D - Asphalt Paving and Roofing Materials and Lubricant Manufacturing. Discharges may be subject to requirements for more than one sector or subsector.
Link to this table
|Subsector||Parameter||Benchmark Values||Effluent Limits|
|D1 Asphalt Paving and Roofing Materials||Solids, Total Suspended (TSS)||100 mg/L 1||Effluent Monitoring Not Required|
|D2 Discharges from Production of Asphalt Emulsions Areas||Solids, Total Suspended (TSS)||Benchmark Monitoring Not Required||23 mg/L daily maximum|
|15 mg/L calendar month average|
|pH||Benchmark Monitoring Not Required||6.0 SU, instantaneous minimum 9.0 SU, instantaneous maximum|
|Oil & Grease, Total||Benchmark Monitoring Not Required||15 mg/L daily maximum|
|10 mg/L calendar month average|
|D3 Miscellaneous Products of Petroleum and Coal||Solids, Total Suspended (TSS)||100 mg/L 1||Effluent Monitoring Not Required|
1If the Permittee is required to comply with Appendix A, part F.1, the benchmark value for Solids, Total Suspended (TSS) is 65 mg/L, instead of 100 mg/L.
Sector D industrial facilities are authorized to use designed infiltration devices or industrial stormwater ponds for stormwater management.
