The revised permit details requirements for 29 different industrial sectors. The requirements described below are for the Glass, Clay, Cement, Concrete, and Gypsum Products Sector (Sector E). Sector E covers a fairly broad range of product types, including flat glass, glass containers, pressed and blown glass, hydraulic cement, structural clay products, pottery and related products, concrete, gypsum, and plaster products, glass products, cut stone and stone products, abrasives, asbestos products, and miscellaneous non metal mineral products, mineral wool and mineral wool insulation products, and non-clay refractories. These requirements are in addition to permit requirements that apply to all sectors.

Review requirements that apply to all sectors

Inspections:
The facility must conduct inspections of dust collection and containment systems.

Good Housekeeping:
The facility must prevent or minimize the discharge of spilled cement, aggregate (including sand or gravel), kiln dust, fly ash, or settled dust from paved portions of the facility that are exposed to stormwater. Each facility must determine the frequency of sweeping or equivalent by the amount of industrial activity occurring in the area and the frequency of exposure to stormwater, but it must be performed at least once a week, if cement, aggregate, kiln dust, fly ash, or settled dust are being handled or processed. The operation must also prevent the exposure of fine granular solids (cement, fly ash, kiln dust, etc.) to stormwater.

Preventative Maintenance:
For facilities producing ready-mix concrete, concrete block, brick, or similar products preventive measures must be implemented that ensure that process wastewater resulting from washing trucks, mixers, transport buckets, forms, or other equipment are discharged in accordance with a separate applicable NPDES permit..

Stormwater Monitoring Benchmarks:
All facilities are required to conduct visual and chemical (benchmark) monitoring. For benchmark monitoring, the benchmark concentrations or values depend on product type:

Clay Products Manufacturers (SIC 3251-3259, 3261-3269):
Total Aluminum 1.5 mg/L
TSS 100 mg/L

Concrete and Gypsum Product Manufacturers (SIC 3271-3275):
TSS 100 mg/L
Total Iron 1.0 mg/L

Cement Manufacturing Facility, Material Storage Runoff:

Timber Products - Wood Products Sector Stormwater Requirements

The Minnesota Pollution Control Agency (MPCA) has issued its revised multi-sector industrial stormwater discharge general permit (MSGP). This permit will replace the existing industrial stormwater permit, which expired in October of 2002.

[Read a summary of the overall Minnesota permit, stormwater monitoring, and sector requirements]

All manufacturing, industrial and “industrial-like” sites that require a permit to discharge stormwater will be required to come into compliance with the revised permit, and to submit an application for permit coverage by either June 1, August 1 or October 1, depending on their industrial sector.

Click here to review a list affected industrial sectors and application deadlines for each sector

The revised permit details requirements for 29 different industrial sectors. The requirements described below are for the Timber Products Sector (Sector A). Sector A covers a fairly broad range of facility types, including log storage or handling areas, mills, producing lumber and wood basic materials, wood preserving, manufacturing finished articles made entirely of wood or related materials, and manufacturing wood buildings or mobile homes. These requirements are in addition to permit requirements that apply to all sectors.

Steam Electric Sector O Power Plant Compliance

The Minnesota Pollution Control Agency (MPCA) has issued its revised multi-sector industrial stormwater discharge general permit (MSGP). This permit will replace the existing industrial stormwater permit, which expired in October of 2002.

[Read a summary of the overall Minnesota permit, stormwater monitoring, and sector requirements]

All manufacturing, industrial and “industrial-like” sites that require a permit to discharge stormwater will be required to come into compliance with the revised permit, and to submit an application for permit coverage by either June 1, August 1 or October 1, depending on their industrial sector.

Click here to review a list affected industrial sectors and application deadlines for each sector

The revised permit details requirements for 29 different industrial sectors. The requirements described below are for the Steam Electric Generating Facilities (Sector O). Sector O covers three primary types of facilities, 1) steam electric power generation; and 2) dual fuel co-generation facilities producing steam.

These requirements are in addition to permit requirements that apply to all sectors.

Good Housekeeping Practices:
The SWPPP must describe and implement procedures to reduce or control the tracking of ash and residue from ash loading areas. Implement housekeeping procedures, such as, dust suppression, containment, or clearing loading areas, floors and roadways of ash and excess water

Inspections
Inspections must include:
a) coal handling areas,
b) switchyards,
c) ash handling areas,
d) areas adjacent to disposal ponds and landfills.

Inspections must include all residue-hauling (i.e. ash) vehicles for proper covering over the load, adequate gate sealing, and overall integrity of the container body. Dischargers must repair, as soon as practicable, vehicles without load covering or adequate gate sealing, or with leaking containers or beds. Two of the monthly inspections must be conducted during runoff events and one of the inspections shall be performed during a snow melt runoff event.

Preventative Maintenance:
The SWPPP must describe and implement measures that prevent or minimize stormwater from contacting fugitive dust emissions from coal handling areas and to prevent or minimize contamination of stormwater runoff from delivery vehicles carrying significant materials arriving at the facility. The SWPP must have procedures ensuring overall integrity of the body or container and procedures to deal with leakage or spillage from vehicles or containers.

The SWPPP must also describe and implement measures that prevent or minimize contamination of surface runoff from oil-bearing equipment in switchyard areas and to retard flows and limit the spread of spills from oil-bearing equipment in switchyards, or collecting runoff in perimeter ditches from these areas.

Spills and Leaks:
The SWPPP must describe and implement measures to reduce the potential for an oil or chemical spill, or reference an SPCC plan, and to visually inspect the structural integrity of all above-ground tanks, pipelines, pumps, and related equipment, and conduct any necessary repairs immediately.

Management of Runoff:
The SWPPP must describe and implement measures that prevent or minimize contamination of surface runoff from areas adjacent to disposal ponds or landfills, and must include procedures to reduce ash residue that may be tracked on to access roads traveled by residue handling vehicles, and reduce ash residue on exit roads leading into and out of residue handling areas.

SWPPP Contents:
The SWPPP must identify:
1) scrap yards, and general refuse areas;
2) short- and long-term storage of construction materials, paint equipment, oils, fuels, used and unused solvents, cleaning materials, paint, water treatment chemicals, fertilizer, and pesticides);
3) landfills and construction sites; and
4) stockpile areas (e.g., coal or limestone piles).

Stormwater Monitoring Benchmarks:
All facilities are required to conduct chemical (benchmark) monitoring. For benchmark monitoring, the benchmark concentrations or values depend on facility type:

Coal Fired and Oil Fired Steam Electric Generating Facilities:
TSS 100 mg/L
Iron 1.0 mg/L

Nuclear and Natural Gas Fired Co-Generation Facilities:
TSS 100 mg/L

In addition, any facilities that maintain coal piles are subject to Effluent Limitations, which require monitoring separate from Benchmark Monitoring requirements.
