Federal Regulations - EPA State Regulations - ADEQ Water and Wastewater – Clean Water Act Stormwater – Clean Water Act Water, Wastewater and Stormwater – Regulation 2, 6
CLEAN WATER ACT • Enacted in 1972 • Major Amendments 1977 and 1982 • Established goals of eliminating releases of high amounts of toxic substances into waters of the U.S. • Set standards for surface water • Does not directly address groundwater contamination • Included in Safe Drinking Water Act and RCRA
WATERS PROTECTED UNDER THE CWA • All waters with a “significant nexus” to “navigable waters” are covered under the CWA • In the 2006 case Rapanos v. United States the Supreme Court held that the term “waters of the United States” • …includes only those relatively permanent, standing or continuously flowing bodies of water “forming geographic features” that are described in ordinary parlance as “streams[,] …oceans, rivers, [and] lakes”
POLLUTION CONTROL STRATEGY IN THE CWA • National Pollutant Discharge Elimination System (NPDES) • Industrial facilities (including manufacturing, mining, oil and gas extraction, and service industries) • Municipal governments and other government facilities (such as military bases), and • Some agricultural facilities, such as animal feedlots
POLLUTION CONTROL STRATEGY IN THE CWA • Point sources may not discharge pollutants to surface water without a permit • EPA has authorized 46 states to issue permits • In the remaining states and territories, permits are issued by an EPA regional office
POLLUTION CONTROL STRATEGY IN THE CWA • Technology-based standards • Water quality standards • Designated uses • Antidegradation policy • Nonpoint sources • Congress exempted some water pollution sources from the point source definition • Agricultural stormwater discharges and irrigation return flows
POLLUTION CONTROL STRATEGY IN THE CWA • Stormwater runoff from industrial sources, municipal storm drains, and other sources were not specifically addressed in the 1972 law • A growing body of water research during the late 1970s and 1980s indicated that stormwater runoff was a significant cause of water quality impairment • Water Quality Act of 1987 – Congress required industrial stormwater dischargers and municipal separate storm sewer systems obtain NPDES permits
MAJOR STATUTORY PROVISIONS • Title I – Research and Related Programs • Title II – Grants for Construction of Treatment Works • Title III – Standards and Enforcement
TITLE III - STANDARDS • Discharge permits required • Technology-Based Standards Program • Municipal sewage treatment plants (POTW) are required to meet secondary treatment standards • Effluent guidelines (for existing sources) and New Source Performance Standards (NSPS) are issued for categories of industrial facilities discharging directly to surface waters • Categorical Pretreatment Standards are issued to industrial users (also called “indirect dischargers”) contributing wastes to POTW. There are 27 categories with pretreatment standards as of 2011.
WATER QUALITY STANDARDS PROGRAM • Water quality standards (WQS) set site-specific allowable pollutant levels for individual water bodies, such as rivers, lakes, streams and wetlands • States set WQS by designating uses for the water body (e.g., recreation, water supply, aquatic life, agriculture) • An antidegradation policy is also issued by each state • Water bodies that do not meet applicable water quality standards with technology-based controls alone are placed on the section 303(d) list of water bodies not meeting standards • States must submit a report every two years (even years) to EPA on the status of all waters of the State – 303(b) report
WATER QUALITY STANDARDS PROGRAM • Water bodies on the 303(d) list require development of a Total Maximum Daily Load (TMDL) • A TMDL is a calculation of the maximum amount of a pollutant that a water body can receive and still meet WQS • Streams and water bodies can have more than one TMDL, i.e. TSS, BOD, DO, etc. • Some states and local governments have TMDLs for watersheds – especially for watersheds that contain drinking water sources • Overall goal is protection of water body or watershed
TITLE IVPERMITS AND LICENSES • State certification of compliance • States are required to certify that discharges authorized by federal permits will not violate the state’s water quality standards • NPDES permits for point sources • The NPDES permit program is authorized by CWA section 402 • Focused on POTWs and industrial wastewater – typically “process” wastewater
TITLE IVPERMITS AND LICENSES • The 1987 WQA expanded the program to cover stormwater discharges explicitly, both from municipal separate storm sewer systems (MS4) and industrial sources • Non-stormwater permits typically include numeric effluent limitations for specific pollutants • Stormwater permits typically require facilities to prepare a Stormwater Pollution Prevention Plan and implement best management practices
NPDES PERMIT STRUCTURE Effluent Limitations • Effluent Guidelines Technology-Based • Secondary Water Quality-Based Monitoring & Reporting Requirements Special Conditions Additional Mon. / Special Studies • Pretreatment • Municipal Sewage Sludge Best Management Practices Compliance Schedules Standard Conditions
NPDES INDIVIDUAL PERMIT PROCESS • Application to ADEQ • ADEQ determines the permit application is administratively complete • ADEQ sends letter to other state and federal agencies • ADEQ notices the public that a NPDES permit has been requested • ADEQ technical review – 90 days • Draft permit sent to EPA for review – 30 days • Draft permit Public Notice – 30 days • Public hearing (if required) – 30 days
ADEQ REGULATION NO. 2Water Quality Standards for Surface Waters in Arkansas • Antidegradation Policy • Water body uses • General Standards • Specific Standards
ADEQ INDUSTRIAL NPDES PERMITS • NPDES Permits • Individual permits • General permits • No-Discharge Permits • Individual • General • Pretreatment Program • Stormwater Program
NPDES PERMITS • Individual Permits • Process water discharges to receiving streams • General Permits • Landfills • Cooling tower & boiler blowdown • Individual treatment • CAFO • Water treatment • Hydrostatic testing • Car/Truck wash • Groundwater cleanup
NO DISCHARGE PERMITS • Individual Permits • Animal waste disposal • Land application – biosolids • Land application – oil & gas waste • Subsurface disposal • General Permits • Septic tank for carwash • One time land application • Saltwater disposal • Land application of water treatment residuals
PRETREATMENT PROGRAM • Industrial wastewater can damage POTW’s • Discharges can be toxic to POTW’s treatment process • Discharges can pass through POTW’s and impair receiving streams • 24 cities in Arkansas have pretreatment programs • ADEQ/EPA monitor pretreatment programs • Categorical/non-categorical discharges
DREDGE AND FILL PERMITS(wetlands, lakes, streams, rivers and other waters of the U.S.) • Under sections 301 and 502 of the Clean Water Act, any discharge of dredged or fill materials into “waters of the United States,” including wetlands, is forbidden unless authorized by a permit issued by the USACE pursuant to section 404 • There are two main types of wetlands permits: general permits and individual permits • General permits (such as the Nationwide Permits) • Individual permits are utilized for actions that are not addressed by a general permit
CASE STUDYNPDES Permit • Industrial process water discharges • Discharges to POTW • Non-categorical discharges • Categorical discharges • POTW requires pretreatment • CASE 1 – POTW discharges to stream with TMDL • CASE 2 – POTW discharges to stream with no TMDL
CASE STUDYNPDES Permit • Industrial process water discharges • CASE 1 – Discharges wastewater to stream with TMDL • CASE 2 – Discharges wastewater to stream with no TMDL
Industrial Stormwater Requirements • Permit Area. This permit includes all areas within the State of Arkansas.

Business Categories and Subcategories. • Facilities subject to stormwatereffluent limitations guidelines, new source performance standards, or toxic pollutants effluent standards under 40 CFR, Subchapter N [except facilities which are exempt under category (xi)]. "Note that the phrase 'toxic pollutant effluent standards' refers to the standards codified at 40 CFR 129 which applies only to manufacturers of 6 specific pesticide products that are defined as toxic pollutants. The phrase does not apply to facilities subject to effluent limitation guidelines for toxics under 40 CFR Subchapter N."
General Permit Requirements • Facilities classified as:
