CANTER*** INTRODUCTION Water pollution abatement programs in the United States have been directed almost entirely toward the elimination of point sources of water pollution-defined in the Federal Water Pollution Control Act' as "any discernible, confined and discrete conveyance... from which pollutants are or may be discharged." 2 Yet officials of the En- vironmental Protection Agency estimate that fifty percent or more of the nation's water pollution is waste picked up from the land by rainfall, which then reaches ground and surface waters through run- off and seepage and not through a pipe or other point source of pollution.3 The waters which drain urban streets, construction sites, agricul- tural areas and other sites of intensive human use are often heavily *Professor of Law and Dean Emeritus, University of Florida Law Center; Director, Water Law Studies of the University of Florida; B.A., 1939, University of Toronto; J.D., 1942, University of Florida.

  • 2017 OKR05 Fact Sheet
    Oklahoma Department of Environmental Quality Water Quality Division Reissuance of OPDES Multi-Sector General Permit OKR05 for Stormwater Discharges Associated with Industrial Activity within the State of Oklahoma Fact Sheet July 5, 2017 2017 OKR05 Fact Sheet Introduction The Oklahoma Department of Environmental Quality (DEQ) is reissuing the OPDES Multi-Sector General Permit (MSGP) OKR05 for stormwater discharges associated with industrial activity within the state of Oklahoma. This Permit will replace the 2011 OKR05 permit that expired on September 4, 2016. All existing and new facilities must obtain an Authorization under this new 2017 OKR05 permit in order to discharge stormwater associated with industrial activity. Under Section 402(p) of the Clean Water Act (CWA), the US Environmental Protection Agency (EPA) promulgated regulations (40 CFR § 122.26), known as the Phase I Stormwater Program, that established permit requirements for stormwater discharges associated with industrial activity. On September 9, 1997, EPA delegated all the responsibility to DEQ to administer stormwater discharges associated with construction and industrial activities and from Municipal Separate Storm Sewer Systems (MS4s). This delegation excluded facilities located on Indian Land, Oil & Gas Exploration fields, and Agricultural Services & Forestry. DEQ issued its first MSGP GP-00-01 on October 2, 2000. This Permit included provisions that industrial facilities in 29 different industrial sectors implement control measures and prepare site-specific Stormwater Pollution Prevention Plan (SWP3). In addition, the OKR05 permit included a 30th sector, available for DEQ to permit additional industrial activities that the DEQ determines require permit coverage for industrial stormwater discharges not included in the other 29 industrial sectors.
