  • Municipal Stormwater Program Audits in California: Findings and Lessons Learned

    ABSTRACT EPA, with the assistance of Tetra Tech and the California Regional Water Quality Control Boards, has conducted 122 on-site audits of municipal stormwater programs over past six years to assess NPDES permit compliance and program effectiveness. Evaluations consisted of a programmatic review of individual MS4s and an in-field verification of these program elements. The project goals ...

  • A technical guide to complying with Federal SPCC Regulations

    Let’s start by clarifying what SPCC is not since SPCC does overlap other Federal and State environmental regulations. SPCC is not: NPDES – Permits under NPDES, such as stormwater or water discharge permits, are required to discharge pollutants into the “navigable waters of United States.” While it is never permitted to discharge “oil” into any waters of the US, there is some overlap with NPDES in ...

  • Integration of Watershed Planning and Wellhead Protection Programs

    For communities using groundwater as the primary source of water supply, delineating, managing, and protecting the wellhead recharge area is essential to assuring a sustainable water resource system. Because many communities are also required to obtain a National Pollutant Discharge Elimination System (NPDES) permit for discharges from municipal separate storm sewer systems (MS4s), delineating ...

  • Developing a Stormwater Infrastructure Geospatial Database for a Large Non-Traditional MS4 System

     ABSTRACT The Massachusetts Department of Conservation and Recreation (DCR) is a state agency which owns and maintains parks, conservation and watershed land, and roadways. They are regulated as a non-traditional MS4 stormwater municipality under the U.S. Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System (NPDES) Phase II program. To satisfy the ...

  • Alternatives for Finding Illicit Discharges to Stormwater Systems

    ABSTRACT Provisions of the National Pollutant Discharge Elimination System (NPDES) permits for stormwater discharges require that permits for municipal separate storm sewers systems (MS4s) shall include a requirement to effectively prohibit problematic non-storm water discharges into storm sewers. Emphasis is placed on the elimination of inappropriateconnections to urban storm drains. ...

  • Airport deicing effluent treatment and regulatory guidelines

    Airport and airplane deicing is employed with the use of brines, salts, alcohols or glycols to remove and prevent or delay the formation of snow and ice.  In the United States (US), the Federal Aviation Administration requires airlines that operate during icy conditions to perform deicing and anti-icing of aircraft and airfield pavement (USEPA 2011a).  These deicing operations use large ...

  • Clean Water Policy Update 2006

    The Clean Water Policy Update 2006 technical session will be divided into two parts: an update from EPA Headquarters personnel and a panel discussion on a “hot” water policy issue. The first panel, “U.S. EPA Office of Water Update,” will include the Director of EPA’s Office of Wastewater Management, James Hanlon, the Director of EPA’s Office of Science and Technology, Ephraim King, and the ...

  • Wetlands for Industrial Wastewater Treatment at the Savannah River Site

    ABSTRACT The A-01 effluent outfall, which collects both normal daily process flow and stormwater runoff from a industrial research facility, did not meet the South Carolina Department of Health and Environmental Control (SCDHEC) National Pollutant Discharge Elimination System (NPDES) permit limits for metals, toxicity, and total residual chlorine at the outfall sampling point. Copper was the ...

  • Wetlands For Industrial Wastewater Treatment At The Savannah River Site: A Case Study

    ABSTRACT The A-01 effluent outfall, which collects both normal daily process flow and stormwater runoff from a industrial park-type area, did not meet the South Carolina Department of Health and Environmental Control (SCDHEC) National Pollutant Discharge Elimination System (NPDES) permit limits for metals, toxicity, and total residual chlorine at the outfall sampling point. However, copper is ...

  • The Challenge of the Future: Operating Emerging Disinfection Technologies

    ABSTRACTThe Clean Water Act (1972 and 1977) established the basis for regulating pollutant discharges into the waters of the United States. This Act contains many provisions regulating pollutant discharges and surface water quality in the United States. This act has also been modified by numerous revisions and amendments since it was enacted in 1972. The National Pollutant Discharge Elimination ...

  • EPA Clean Water Act: New Regulations re: `Waters of the United States`

    The Environmental Protection Agency (EPA) published a final rule defining the scope of waters protected under the Clean Water Act… The rule will ensure protection for the nation’s public health and aquatic resources, and increase CWA program predictability and consistency by clarifying the scope of ‘‘waters of the United States’’ protected under the ...

  • Development of Treatment Systems for Nitrate Ester Wastewater to Meet Toxicity Based Effluent Limits

    ABSTRACT Dyno Nobel, Inc. (Dyno Nobel) operates a plant near Carthage, Missouri, which manufactures various explosives, including commercial dynamite. The plant produces nitrate esters, including primarily nitroglycerine (NG) and ethylene glycol dinitrate (EGDN), for use in explosive products, using continuous flow and batch nitrators. Diethylene glycol dinitrate (DEGDN) and metriol trinitrate ...

  • A Water Quality Modeling Approach to Negotiating NPDES Wastewater Permits

    ABSTRACTJohnson County Wastewater (JCW) of Overland Park, Kansas operates two wastewater treatment plants on Indian Creek, the Douglas L. Smith Middle Basin WWTP (MB) and the Tomahawk Creek WWTP (TC), which discharges to Indian Creek about 7 creek miles downstream of the MB discharge location. In 2004, the Kansas Department of Health and Environment (KDHE) issued draft revisions to the NPDES ...

  • World War II Memorial, DC - Case Study

    In 2003, AdEdge Water Technologies began working closely with EarthTech, the assigned engineering firm responsible for specifying and selecting the various water treatment systems serving the new National World War II Monument in Washington, DC. Stormwater and groundwater control and treatment are essential aspects of this project given the location of the site on the Mall adjacent to the ...

  • Stormwater and Spill Management at an Iron Pipe Foundry in Texas

    ABSTRACTLarge industrial sites have had permits for storm water discharges under the NPDES program of the Clean Water Act since the mid to late 80’s. Recent emphasis has been placed on regulated facilities to prepare and implement Spill Prevention, Control and Countermeasure (SPCC) plans under the Oil Pollution Prevention Act (40 CFR 112). A large iron pipe foundry in Texas has several storm ...

  • Modeled Flow Duration Variations, Pollutant Discharges, and Costs for Different Stormwater Controls

    ABSTRACTRunoff volume and pollutant discharges increase with development, with associated detrimental receiving water effects. These increases can be partially controlled by installing stormwater control practices, such as wet detention pond at outfalls, using conservation design controls such as grass swales and bioretention devices, and by improved development practices that reduce the amounts ...

  • Stormwater Solids Reduction for NPDES Permits

    Finally obtaining a National Pollution Discharge Elimination System (NPDES) Permit is often a relief but is by far not the end of the story. Meeting the requirements of that permit often proves to be quite difficult and stiff fines are freely doled out to those who fail to meet regulatory limits. For one Midwest jet propulsion manufacturing facility, the issue of total daily solids discharge ...
