The revised Minnesota permit details requirements for 29 different industrial sectors. The requirements described below are for the Landfills and Land Application Sites Sector (Sector L). Sector L includes waste disposal at landfills and land application sites that receive or have received industrial waste, including sites subject to regulation under Subtitle D of RCRA. These requirements are in addition to permit requirements that apply to all sectors.

Review requirements that apply to all sectors

Inspections:
The facility must inspect all active operating landfills and land application sites at least once monthly, including areas of landfill that have not yet been finally stabilized; active land application areas, areas used for storage of material and wastes that are exposed to precipitation, stabilization, and structural control measures; leachate collection and treatment systems; and locations where equipment and waste trucks enter and exit the site. Inspections must nsure that sediment and erosion control measures are operating properly.

Erosion and Sediment Control:
The facility must implement sediment control practices on all down gradient perimeters before any upgradient land disturbing activities begin. These practices should remain in place until final stabilization has occurred. Sites must also provide temporary stabilization for the following: materials stockpiled for daily, intermediate, and final cover; inactive areas of the landfill; landfill areas that have gotten final covers but where vegetation has yet to establish itself; and land application sites where waste application has been completed but final vegetation has not yet been established.

Good Housekeeping:
The operation must provide protected storage areas for pesticides, herbicides, and fertilizers.

Preventive Maintenance:
Sites must maintain the following: all containers used for outdoor chemical and significant materials storage; all elements of leachate collection and treatment systems, to prevent commingling of leachate with stormwater; the integrity and effectiveness of any intermediate or final cover (including repairing the cover as necessary), to minimize the effects of settlement, sinking, and erosion.

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

Municipal Solid Waste Landfill(MSWLF) areas closed in accordance with 40 CFR 258.60:
TSS 100 mg/L

Any open or closed non-hazardous waste landfills and land application sites, which do not discharge to surface water(s), and where stormwater that has directly contacted solid waste:
TSS 100 mg/L
Total Iron 1.0 mg/L

Any landfill that discharges to surface water(s), and stormwater that has directly dontacted solid waste (pursuant to 40 CFR pt. 445, subp. B.):
TSS 100 mg/L
BOD 25 mg/L
Total Ammonia 34.8 mg/L
Total Zinc 0.234 mg/L
pH 6-9

Some landfills may also be subject to effluent limits under the MPCA permit.

The revised permit details requirements for 29 different industrial sectors. The requirements described below are for the Automobile Salvage Yards Sector (Sector M). Sector M includes sites primarily engaged in the dismantling or wrecking used motor vehicles for parts recycling or resale and scrap. These requirements are in addition to permit requirements that apply to all sectors.

Employee Training:
The SWPPP must address the following areas in the employee training program: proper handling (collection, storage, and disposal) of oil, used mineral spirits, anti-freeze, mercury switches, refrigerants, and solvents.

Good Housekeeping:
The SWPPP must include to the maximum extent feasible:
1) store all batteries indoors;
2) recycle lead battery cable ends and wheel balancing weights;
3) remove all fluids from vehicles and recycle or dispose accordingly;
4) remove and segregate mercury switches and mercury containing devices;
5) recycle fuels,
6) remove and dispose of refrigerants as required with complete avoidance of venting to atmosphere;
7) remove and dispose of glycols as required;
8) remove and recycle all lead parts;
9) separate and recycle plastics or dispose as solid waste;
10) store all engines and transmissions (that have been removed from vehicles) in covered areas not exposed to precipitation.

Inspections:
The site must immediately inspect vehicles arriving at the facility for leaks. The site must inspect for signs of leakage, all equipment containing oily parts, hydraulic fluids, any other types of fluids, or mercury switches; and also inspect all vessels and areas where hazardous materials and general automotive fluids are stored, including mercury switches, brake fluid, transmission fluid, refrigerants, and antifreeze.

The facility must conduct two of the monthly inspections during runoff events. One of the inspections shall be performed during a snow melt runoff event. Each inspection must 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.


Stormwater Controls:
Each site must implement the following management practices: berms or drainage ditches on the property line (to help prevent run-on from neighboring properties); installation of detention ponds; installation of filtering devices such as sand filter or mixed media filters, and oil and water separators. Engines and transmissions, and similar oily parts shall be stored in covered areas or, at a minimum, be covered with impermeable tarps or similar material to eliminate contact with stormwater; and above ground liquid storage tanks must have secondary containment.

If stormwater ponds are built, they must meet design standards listed in the permit. No new stormwater infiltration devises are allowed.

Mercury Minimization Plan:
All automotive recyclers must enroll in the End of Life Vehicle Solutions Corporation (ELVS) program. The ELVS program took over the management of the Minnesota Mercury Recovery Program for automotive recyclers and scrap metal recyclers in May 2006. ELVS provides these recycling operations with collection buckets and will pay the costs of transportation, retorting/recycling or disposal of elemental mercury from the automotive switches. ELVS provides educational materials to promote vehicle and scrap metal recycling and proper management of mercury switches and other mercury containing devices.

In addition to the ELVS program, each site must also evaluate its facility to identify and determine any additional sources of mercury that may be introduced to, or used at, the facility. This may include mercury containing devices such as switches including float switches, manometers, barometers, batteries, flame sensors, hydrometers, manometers, medical devices, lamps, mercury compounds, pyrometers, relays, thermometers, freezers, pressure gauges, thermostats, etc. The plan must evaluate how any mercury containing devices may be removed to the extent feasible, or segregated to avoid spills and contact with stormwater.

Stormwater Monitoring Benchmarks:
All facilities are required to conduct visual and chemical (benchmark) monitoring. For benchmark monitoring, the benchmark concentrations or values apply to all facility types:

TSS 100 mg/L
Total Aluminum 1.5 mg/L
Total Lead 0.164 mg/L
Total Iron 1.0 mg/L

Note: Benchmarks for lead, aluminum, iron were derived based on the Aquatic Life Standards for these parameters in Minnesota Rules.
