South Dakota 2012 Impaired Waters List

The South Dakota Department of Environment and Natural Resources (DENR) has submitted its 2012 Integrated Report for Surface Water Quality Assessment to the U.S. Environmental Protection Agency (EPA). The biennial report, required under the federal Clean Water Act, was due to EPA by April 1. The Integrated Report contains an assessment of the surface water quality of South Dakota’s waters, a description of South Dakota’s water quality monitoring programs, pollutants causing impairments of the water bodies, and identification of waters targeted for total maximum daily load development. A total maximum daily load is a determination of the amount of pollution a waterbody can receive and still maintain water quality standards.

The 2012 report lists 155 waterbodies or waterbody segments needing a total maximum daily load. Of those listed, 92 (or 59%) are stream and river segments and 63 (or 41%) are lakes that occasionally violate water quality standards. Since the last biennial report in 2010, 69 total maximum daily loads have been completed or determined to be unnecessary, 79 are in progress, and 84 are planned.

Draft General Permit For Infrequent Temporary Wastewater Discharges

The South Dakota Department of Environment & Natural Resources (SDDENR) has released its draft general NPDES permit to cover certain types of infrequent or on-time discharges of wastewater and/or stormwater. Under Federal Clean Water Act rules, these types of discharges can not occur unless covered under an NPDES permit. The types of discharges which would be allowed under the South Dakota permit, once finalized, include:

Construction dewatering,
Pump testing of water wells,
Discharges from swimming pools and similar structures,
Discharges of petroleum contaminated ground water from remediation sites,
Other types of short-term discharges meeting specific criteria.

In order to be covered under the general permit, dischargers will need to submit an application to the SDDENR.

The draft NPDES general permit specifies effluent limits and monitoring that must be conducted during the discharge. It also outlines specific Best Management Practices (BMP) that should be followed before, during and after the discharge occurs.

The draft general permit was placed on 30-day public comment, and will be finalized and available for use after comments are received and the permit modified, if necessary.

South Dakota Revised Industrial Stormwater Permit

The South Dakota Department of Environment and Natural Resources (DENR) has drafted a revised general stormwater discharge permit for industrial dischargers in the State. The existing permit expired in 2008, but has remained in effect until the revised permit is finalized.

The revised permit that has been draft is similar in many aspects to the existing permit, including requirements for stormwater pollution prevention plan (SWPPP), site inspections, and prohibition on non stormwater discharges, such as equipment and vehicle washing.

There are some important differences in the working draft that will change the compliance requirements for South Dakota industrial sites.

Multi Sector Industrial Requirements. The current draft permit does not include the industrial sectors associated with the EPA Multi Sector General Permit (MSGP), however it does segregate seven industrial sectors:

• Metals
• Transportation (other than airports)
• Air Transportation, Airports
• Food and Kindred Products
• Auto Salvage
• Landfills
• Waste Treatment

The draft permit is expected to have the same compliance requirements for all industrial facilities, including the seven sectors, with the exception of monitoring requirements.

Stormwater Monitoring Requirements. Under the draft permit requirements, all industrial sites will have to conduct storm water discharge monitoring. All sites would have to collect samples during the first year of the permit and report results to SDDENR. The chemical parameters to be tested by each site will depend on the industrial sector the site falls into.

Under the current plan, monitoring results reported to DENR will be used to determine if industrial benchmark concentrations will be established during the next permit revision and as a basis for future benchmarks.

The revised permit is expected to be released for public review and comment in the Fall 2010; South Dakota DENR anticipates that the new permit will be effective January 1, 2011.

Revised CAFO Permit Requirement Agreement

On May 25, 2010, environmental groups and the Environmental Protection Agency (EPA) signed a settlement agreement resolving their challenges filed in federal court to the 2008 Final Concentrated Animal Feeding Operations (CAFO) National Pollutant Discharge Elimination System (NPDES) Rule.

The settlement agreement requires EPA to issue a guidance document, no later than May 25, 2011, that specifies the kinds of operations and factual circumstances that EPA anticipates may trigger the duty for CAFOs to apply for NPDES permits. The agreement also requires EPA to propose a rule to require all owners or operators of CAFOs to submit information to EPA, regardless of whether they discharge or propose to discharge. EPA is required to propose such a rule, receive public comment and take final action on the proposed rule by May 25, 2012.

DENR Revised Construction Stormwater Permit

On February 1, 2010, the revised NPDES discharge permit for construction site stormwater discharges takes effect in South Dakota. The South Dakota Department of Environment & Natural Resources (DENR) issued the revised permit on December 31, 2009; this permit replaced the previous, which had been issued in 2002 and has been expired since 2007. The revised permit makes a number of changes to the stormwater compliance requirements needing to be met at affected construction sites.

Some of the changes include:

Permit

• NOI must be signed by the owner
• SWPPP must be developed before the NOI is submitted
• All SWPPPs, inspection reports, or other information must be signed and certified by a signatory official or by a “duly authorized representative” (Signatory authority must identify authorized representative and submit written authorization letter to DENR)

Stormwater Controls

• Controls must be designed to meet 2 inch 24 hour event (2-year, 24-hour storm event)
• Sediment basins required if >10 acres disturbed at one time, where possible
• Sediment traps or other equivalent controls required if <10>
• All storm drain inlets must be protected until site is stabilized
• Install velocity dissipation devices at points with high flows
• Soil stockpiles must have silt fence or other effective controls Properly store and dispose of litter, construction debris, and chemicals

Inspections

• Once every 7 days
• Within 24 hours after storm that is 0.5 inches or greater

Maintenance

• Remove sediment when ponds are 50% full
• Clean silt fences before sediment is 50% of the fence height
• Must minimize dust generation and tracking; street sweeping required at a minimum
• Remove sediment that accumulates off-site
• Site must be stabilized within 14 days after construction has ceased at the site

SD DENR Multimedia General Permits - Air and Stormwater Permit

South Dakota is one of two States that offer a Multimedia General Permit. There is a clear advantage for permitting agencies to develop general permits to the regulated community. A single permit can be prepared and issued which can be used by many permittees. In most cases, the general permit option benefits the permit holder as well, including:

• Significant reduced time to receive permit(s),


• Clear understanding of permit requirements and limitations before applying for coverage,

Permittees that can not accept the requirements or limitations in the general permit have the option to apply for an individual permit.

Multimedia General Permits incorporate the requirements that apply to different permitting programs. To date, the permitting programs which have been combined are Air Emission Permits and Stormwater Discharge Permits. In this case, permittees that require both an air permit and a stormwater permit apply to be covered under a single Multimedia General Permit.

Because the regulatory requirements for air emission and stormwater discharge permits are sector- or industry-specific, the multimedia general permits offered are usually limited to a fairly narrow industrial sector. And therefore, because a multimedia general permit will apply to a smaller number of potential permittees, many States have not devoted significant resources to develop many such permits.

Two States have developed one or more Multimedia General Permits:

Alabama – (ADEQ): In February 2009, ADEQ promulgated a multimedia general permit for Dry Litter Poultry Animal Feeding Operations – a type of regulated Confined Animal Feeding Operation or CAFO. The general permit incorporates requirements for air emission permitting and compliance and stormwater permitting and compliance.

South Dakota – (SDDENR): DENR has three Multimedia General Permits for asphalt plants, rock crushing operations, and concrete plant. Like the Alabama permit, the South Dakota permit combines air emission and stormwater discharge requirements.

Because permittees need to accept both air emission and stormwater discharge requirements and limits, it becomes even more important for sites considering multimedia general permit coverage carefully review the compliance requirements.
