Corps Rulemaking on Water Supply and Surplus Waters

On December 16, the U.S. Army Corps of Engineers (Corps) published a notice of proposed rulemaking, 81 FR 91556, updating its policies on the use of Corps reservoir projects for domestic, municipal, and industrial water supply. The revisions are intended to “enhance the Corps’ ability to cooperate with State and local interests in the development of water supplies,” take into account court decisions, legislative provisions and other developments, to bring greater clarity and consistency across regions, and to facilitate or avoid interfering with other lawful uses of water. The Corps proposes to define key terms and improve its interpretations and practices under the authority of the 1944 Flood Control Act (33 USC §708) and the 1958 Water Supply Act (43 USC §390b).  Further information may be found here.  Comments may be posted to www.regulations.gov under docket #COE-2015-0016 through May 15.  A selection of some of the related letters submitted is included below:

EPA Rulemaking on Water Quality Standards for Tribes

EPA is considering a rulemaking effort regarding baseline Water Quality Standards for hundreds of tribes without Treatment as States authority. EPA first informed WSWC about this effort during our Council meeting in Washington, D.C. in March 2016, and reached out in multiple webinars during the year to provide information and answer questions.
On September 19, 2016, the EPA Administrator signed an advance notice of proposed rulemaking (ANPRM) to invite comments on whether to establish federal baseline water quality standards (WQS) for Indian reservation waters that do not currently have Clean Water Act (CWA)-effective WQS in place, and if so, what those WQS should be and how they should be implemented. Additional information is available at: https://www.regulations.gov/docket?D=EPA-HQ-OW-2016-0405 or at EPA’s site https://www.epa.gov/wqs-tech/advance-notice-proposed-rulemaking-federal-baseline-water-quality-standards-indian#comment
The deadline to respond to EPA’s solicitation for comments was December 28, 2016. A selection of some of the related letters submitted is included below:
