Barack Obama was seven months into his first term as President of the United States, the World Health Organization had declared a H1N1 flu pandemic, and the California State Water Resources Control Board (State Board) adopted the current Construction General Permit for Stormwater Discharges (Permit or CGP).  It was September 2009.  Now, having administratively extended the Permit since 2014 when, by its terms, the Permit expired, the State Board may, under a schedule released late last year, soon release a new draft CGP for public comment, with a goal of adopting it late this summer.

EPA will be accepting public comments on the proposal until May 1, 2020.

One of the Supreme Court’s recurring environmental law topics is the scope of Clean Water Act (CWA) jurisdiction. Various aspects of CWA jurisdiction and implementation have been addressed over the years by the Court, including the meaning of “navigable waters” in U.S. v. Riverside Bayview Homes, Inc. (1985); Solid Waste Agency of N. Cook Cnty v. Army Corps of Eng’rs (2001); and Rapanos v. U.S. (2006), and judicial review of agency actions related to the applicability of the CWA dredge and fill permit program in Sackett v. EPA (2012) and U.S. Army Corps of Eng’rs v. Hawkes Co. (2016). Most recently, the Supreme Court heard oral argument on November 6 in County of Maui v. Hawai’i Wildlife Fund, et al., a case that addresses the applicability of the CWA’s prohibition on “point source” discharges to “navigable waters” to releases from point sources to groundwater. The Court granted certiorari to address whether releases from point sources that are carried to navigable waters by groundwater are regulated under the federal NPDES permit program or under state non-point source management programs.

Continuing its vanguard approach to environmental regulation, California is poised to incorporate Total Maximum Daily Load (TMDL)-specific requirements into its industrial storm water general permit (IGP). TMDLs are pollutant- and water body-specific and establish the maximum amount of a pollutant a water body can receive while meeting water quality standards. Once effective, these new requirements will provide additional avenues of attack for the already active Clean Water Act citizen suit docket. …

California is considering the first-in-the-nation general industrial stormwater permit incorporating Total Maximum Daily Load-related numeric action levels and numeric effluent limitations.
