Review a summary of the ADEQ Industrial Stormwater Permit

The proposed permit details requirements for 30 different industrial sectors. The requirements described below are proposed for the Steam Electric Generating Facilities (Sector O). Sector O covers three primary types of facilities, 1) steam electric power generation using coal, natural gas, oil, nuclear energy, etc., to produce a steam source; 3) dual fuel co-generation facilities; and 3) alternative fuel generating facilities used to produce 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 fugitive emissions and control the tracking of coal dust. Sites must implement effective controls to minimize contamination of precipitation or surface runoff from fuel oil and chemical and other material handling areas.

Inspections
Inspections must include:
a) coal handling areas,
b) delivery vehicles,
c) Fuel unloading areas,
d) areas adjacent to disposal ponds and landfills.

Monthly 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.

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 visual and chemical (benchmark) monitoring. For benchmark monitoring, the benchmark concentrations or values are:

All Electric Generating Facilities:
Iron 1.0 mg/L

The permit also has EFFLUENT LIMITS for pH and TSS for discharges from coal piles

Revised Arizona ADEQ Stormwater Permit Requirements for Dischargers Near Impaired Waters or Unique Waters

On February 29, 2008, the revised Arizona Department of Environmental Quality (ADEQ) general permit for the discharge of stormwater from construction sites became effective. This permit replaced an earlier general permit which had expired. The revised general permit now applies to all construction sites greater than one acre in size, with the exception of sites located on Indian lands within the State. For these sites, a different permit, issued by U.S. EPA, applies.

The requirements under the ADEQ permit will change substantially depending on the location of the project. The key criteria will be whether the site is within ¼-mile of:

• An impaired water
• A listed unique water (also known as an “Outstanding Arizona Water”, or OAW)

For project sites located within this radius, significantly more stringent permit compliance requirements may apply which include:

• Submittal of SWPPP with NOI, and extended waiting period for permit coverage
• Additional prohibitions on non-stormwater discharges
• Additional prohibitions on post-construction discharges
• Additional inspection requirements
• Stormwater monitoring

For project sites located with ¼-mile of either an impaired water or a listed unique water, a Stormwater Monitoring Plan must be developed and implemented. Monitoring of stormwater includes visual monitoring each week and collection and analysis of samples when stormwater is discharged. Monitoring results are then reported to ADEQ on Discharge Monitoring Report (DMR) forms.
