Impaired Waters and Outstanding Arizona Waters Requirements Under Proposed ADEQ Permit

The Arizona Department of Environmental Quality (ADEQ) has released a draft Construction General Permit (AZG2008-001). This permit replaces the previous construction general permit that was issued for a five-year term by ADEQ. As written, this general permit becomes effective on March 1, 2013.

The draft permit coverage has the following conditions and requirements apply if any portion of the construction site is located within 1/4 mile of a receiving water listed as impaired under section 303(d) of the Clean Water Act:

• The operator must submit a copy of the SWPPP with the NOI to ADEQ; and
• The SWPPP must include a sampling and analysis plan for analytical monitoring if there is potential for discharges from the site to include the pollutant(s) for which the receiving water is impaired. If the operator can demonstrate there is no reasonable expectation that construction activities could be an additional source of the identified pollutant(s), analytical monitoring is not required. As part of this demonstration, the operator must consider all on-site activities, including the potential for the pollutants (metals, nutrients, etc.) to be present in site soils. The demonstration must be included in the SWPPP submitted for ADEQ’s review;
• If a discharge contains pollutants for which a Total Maximum Daily Load (TMDL) has been established, the SWPPP must specifically identify control measures necessary to ensure the discharges will be consistent with the provisions of the TMDL.

For discharges to outstanding Arizona waters (OAW) the following conditions and requirements apply if any portion of the construction site is located within 1/4 mile of a receiving water listed as an OAW in A.A.C. R18-11-112(G):

• The operator must submit a copy of the SWPPP with the NOI to ADEQ; and
• The SWPPP must include a sampling and analysis plan for analytical monitoring of pollutants expected to discharge from the site, including sediment.

Arizona DEQ Stormwater Monitoring and Industrial Storm Water Benchmarks

In December 2010, the Arizona Department of Environmental Quality (ADEQ) issued the Multi-Sector General Permit (MSGP) for industrial stormwater discharges. The revised permit included significant changes to stormwater discharge requirements for permitted sites, which are now divided into 29 industrial sectors. One of the most significant changes was the requirement for sampling stormwater and reporting results to ADEQ. The monitoring requirement begins immediately after permit coverage begins. ADEQ has defined monitoring seasons in the permit:
Summer wet season: June 1 – October 31
Winter wet season: November 1 – May 31
The frequency for stormwater sampling in the permit is at least twice each wet season (summer and winter) from each monitoring location.

All sites permitted under the MSGP (with some limited exceptions) will have to collect stormwater samples and have samples analyzed for their sector-specific benchmark parameters. If one or more benchmarks are exceeded, sites will be required to upgrade their pollution prevention measures and will need to do further stormwater monitoring.

Some stormwater benchmarks that apply to several sectors include:

Ammonia 2.14 mg/L
Biochemical Oxygen Demand (BOD) 30 mg/L
Chemical Oxygen Demand (COD) 120 mg/L
pH 6.0 – 9.0 s.u.
Total Aluminum 0.75 mg/ L
Total Arsenic 0.15 mg/L
Total Cyanide 0.022 mg/ L
Total Iron 1.0 mg/L
Total Magnesium 0.064 mg/L
Total Mercury 0.0014 mg/L
Total Selenium 0.005 mg/L
Total Suspended Solids (TSS) 100 mg/L


Since the 1980s, the U.S. Environmental Protection Agency (EPA) has collected industry-sector data on stormwater discharge. The linked presentation provides a comparison of these historic industrial stormwater results to the many of the ADEQ stormwater benchmark concentrations. The results are discussed in context of which stormwater benchmark parameters have a higher potential for exceedance of benchmark values. This presentation also discusses which of the industrial sectors have a higher potential for exceedance of their specific benchmark values.

Note: Arizona uses the same benchmark concentrations used by EPA and many other States; although the this linked presentation was specific to Minnesota, the analysis and conclusions apply to Arizona.

The Arizona Department of Environmental Quality (ADEQ) recently released an updated draft of its proposed multisector industrial stormwater discharge general permit, known officially as the AZPDES Multi-Sector General Permit, or MSGP 2010. This permit, once promulgated, will replace the existing industrial stormwater permit, which expired in 2005.

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 Asphalt Paving and Roofing Materials and Lubricant Manufacturing Sector (Sector D). Sector D covers several facility types, including manufacturing asphalt paving mixtures blocks and roofing materials, portable asphalt plant facilities, and manufacturing lubricating oils and greases and miscellaneous products of petroleum and coal. These requirements are in addition to permit requirements that apply to all sectors.

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:

Permanent Asphalt Paving and Roofing Materials (SIC 2951, 2952):
TSS 100 mg/L

The permit also establishes EFFLUENT LIMITS for stormwater discharges from asphalt emulsions facilities

Timber Products Sector A - Arizona Requirements

The Arizona Department of Environmental Quality (ADEQ) recently released an updated draft of its proposed multisector industrial stormwater discharge general permit, known officially as the AZPDES Multi-Sector General Permit, or MSGP 2010. This permit, once promulgated, will replace the existing industrial stormwater permit, which expired in 2005.

Review a summary of the ADEQ Industrial Stormwater Permit

The proposed permit details requirements for 29 different industrial sectors. The requirements described below are proposed 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.

Inspections:
If the facility performs wood surface protection and preservation activities, monthly inspections must include processing areas and treated wood storage areas to assess the effectiveness of practices to eliminate the deposit of treatment chemicals on unprotected soils and eliminate all contact with stormwater discharges.

Industry-Specific Stormwater Controls:
The facility must have secondary containment for all significant materials stored indoor and outdoor, (e.g. arsenic, chromium, zinc, copper, and phenolic solution storage tanks and structures). Facility must also drain containment stormwater for outdoor storage tanks and structures only after inspection demonstrates that no stormwater contact with solutions has occurred.

Potential Pollutant Sources:
If the operation uses chlorophenolic, creosote, or chromium-copper-arsenic formulations for wood surface protection or preserving, the SWPPP must document 1) areas where contaminated soils, treatment equipment, and stored materials still remain, and 2) the management practices employed to minimize the contact of these materials with stormwater runoff.

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:

General Sawmills and Planing Mills (SIC 2421):
COD 120 mg/L
TSS 100 mg/L
Zinc 0.04 to 0.26 mg/L, depending on hardness

Wood Preserving (SIC 2491):
Total Arsenic 0.15 mg/L
Total Copper 0.004 to 0.033 mg/L, depending on hardness

Log Storage and Handling (SIC 2411):
TSS 100 mg/L

Hardwood Dimension and Flooring Mills and others:
TSS 100 mg/L
COD 120 mg/L

The permit also established EFFLUENT LIMITS for discharges from log spray-down areas

Electric Generation Facilities - Proposed ADEQ Requirements

The Arizona Department of Environmental Quality (ADEQ) recently released an updated draft of its proposed multisector industrial stormwater discharge general permit, known officially as the AZPDES Multi-Sector General Permit, or MSGP 2010. This permit, once promulgated, will replace the existing industrial stormwater permit, which expired in 2005.

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
