  • Stormwater: Questions and Answers

    The whole subject of Stormwater is complicated. Here's a chance for you to check out some of the most frequently asked questions about stormwater . . . and their answers. What is an NPDES (National Pollutant Discharge Elimination System) permit? The Clean Water Act prohibits anybody from discharging 'pollutants' through a 'point source' into a 'water of the United States' unless they ...

  • Evaluation of stormwater BMPs for implementing industrial stormwater permitting strategy

    This study assesses the performance of stormwater best management practices (BMPs) in industrial sectors and their effluent quality to facilitate the development of technology-based numerical effluent criteria. Generally, retention ponds outperform other BMP types for reducing total suspended solids, and media filter and wetland basins outperform other BMPs for metal removal. Detention basins ...

  • Don’t Forget about Stormwater Management

    Whether you’re an industrial maintenance manager or retail store manager, one of your many responsibilities may be to keep your property compliant with environmental rules and regulations. From waste management to vapor intrusion, the multitude of compliance-related issues can be daunting.It therefore comes as no surprise that for most retailers, the issue of stormwater management has not always ...

  • Stormwater Best Management Practices (BMP)

    Storm water is the result of rain or snow melt that collects in an area that can drain from into a nearby body of waters such as a lake or river. The water can collect on roof tops, parking lots, saturated ground, roads, etc. The problem is that many of the pollutants of our modern living such as oil, grease, pesticides, sediment, salt, and animal waste are washed away within the storm water and ...

  • Lake Tahoe redevelopment project addresses stormwater compliance problem with passive filtration system

    Untitled Document Ski Run Marina is an integral component of a redevelopment project coordinated by the South Tahoe Redevelopment Agency in the northeast section of ...


  • Washington State DOE stormwater report - Case Study

    Fitesa, a non-wovens manufacturer in the state of Washington consistently tests stormwater but experienced problems meeting the stormwater standards for zinc and copper discharge. Zinc is used in galvanized metal, shingles, finishes in paints, and car tires—zinc iseverywhere. Copper is used in items such as in brake linings and pressure treated lumber. At sites near heavily traveled roads, ...

  • 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 ...

  • Measuring the Effectiveness of Watershed-Based General Stormwater Permitting

    ABSTRACTThe U.S. EPA and most water resources professionals advocate holistic and adaptive watershed management approaches to the protection and restoration of aquatic ecosystems by encouraging pollution control strategies that are developed through collaborative partnerships within a hydrologic boundary. This paper evaluates the effectiveness of the holistic adaptive management approach through ...

  • Retrofitting an Existing Stormwater System to Meet Numerical Effluent Limits - Stormwater Management at Seattle-Tacoma International Airport

    ABSTRACTOwned and operated by the Port of Seattle, Seattle-Tacoma International Airport (STIA) is the 28th busiest airport in the world. A Section 401 Water Quality Certification was issued to the Port to allow its expansion projects to proceed. This certification required existing portions of the airport be retrofitted to meet current stormwater standards. In addition, the Port’s renewed NPDES ...

  • 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 ...

  • 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 ...

  • Micropollutants in stormwater runoff and combined sewer overflow in the Copenhagen area, Denmark

    Stormwater runoff contains a broad range of micropollutants. In Europe a number of these substances are regulated through the Water Framework Directive, which establishes Environmental Quality Standards (EQSs) for surface waters. Knowledge about discharge of these substances through stormwater runoff and combined sewer overflows (CSOs) is essential to ensure compliance with the EQSs. Results from ...

  • Building soils for storm water compliance and successful landscapes

    THE SOILS for Salmon project - initiated in 1999 by the Washington Organic Recycling Council (WORC) - has been building momentum through collaboration with the Washington Department of Transportation (WSDOT), regulators at the state Department of Ecology, local governments, scientists, and green leaders in the building, landscape and development industries. Over the years, the Soils for Salmon ...

  • A Guide to Oil in Water Monitoring for Environmental Compliance

    Applications for industrial oil in water monitoring can vary greatly. In upstream and midstream oil and gas production applications, monitoring separation efficiencies is key to optimize production rates, preventative maintenance, chemical use, flow, and environmental compliance. Separated water from the oil is called produced water and it must be cleaned of oil before disposal or ...

  • Erosion and Sediment Control: Navigating NPDES Regulations, the SWPPP, and Techniques for Compliance

    Erosion and Sedimentation: Why Are They a Problem? The US Environmental Protection Agency lists sediment as the single most common pollutant in rivers, streams, lakes, and reservoirs. With all the potentially harmful chemicals and substances in the world, it seems odd to many people that sediment—dirt, essentially—is singled out as the major culprit. Yet these particles of ...

  • Oil-Water Separator with New Coalescing Media Handles High Load Stormwater at HydroElectric Powerplant to Yield Zero Oil Discharge

    Background Removal of oil from water before the water is discharged into a river or other body of water is an important environmental goal. In order to accomplish this, a major hydropower producer in the southern United States contracted with HydroQuip, Inc.* for the supply of a state of the art oil/water separator. The power plant had several goals, but the most important was that in ...

  • Levels and patterns of fecal indicator bacteria in stormwater runoff from homogenous land use sites and urban watersheds

    Routine stormwater monitoring programs focus on quantification of average fecal indicator bacteria (FIB) concentration at the terminal watershed discharge point. While important for permit compliance, such monitoring provides little insight into relative bacteria levels from different land use types or the mechanisms that influence FIB concentrations. The goal of this study was to quantify the ...

  • 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 ...
