Moffat Project Final EIS to move toward completion

Published March 4, 2013

OMAHA, Neb. — The U.S. Army Corps of Engineers, Omaha District, has announced a tentative date for the release of its Final Environmental Impact Statement for Denver Water’s Moffat Collection System Project. With federal and state agency and the applicant, Denver Water’s concurrence, the Corps anticipates that the projected Final EIS will be released in February 2014.  At that time, the public will have an opportunity to review and comment on the Final EIS, which will in turn be considered prior to final decision-making by the Corps.  

The Final EIS and public comments will serve as a basis for the Corps’ decision on whether to issue or deny a Section 404 Permit for the enlargement of Gross Reservoir, located in Boulder County, Colo. The Corps’ regulatory program is authorized by Section 404 of the Clean Water Act to regulate certain waterways-related activities. As the lead regulatory agency for the Moffat Project EIS, the Corps is charged with the responsibility of impartially reviewing Denver Water’s proposal to ensure compliance with environmental and other federal laws.   

“We are confident that our latest schedule gives us a path forward toward an expeditious conclusion to the federal permit evaluation process,” said Omaha District Commander Col. Joel R. Cross. “Everyone involved with the project is committed to working together to fulfill the requirements of a Final EIS, which will bring us closer to making a final decision on Denver Water’s project.”  


The state of Colorado is proactively seeking solutions for meeting its future water needs while ensuring the health of its rivers and streams. Through the Moffat Collection System Project, Denver Water proposes to meet its water supply obligations and provide a more reliable supply infrastructure, while advancing its environmental stewardship.  The project intends to enlarge the existing 41,811-acre foot Gross Reservoir to 113,811 AF,  which equates to an expanded water surface area from 418 acres to 818 acres. Using existing collection infrastructure, water from the Fraser River, Williams Fork River, Blue River and South Platte River would be diverted and delivered to Denver’s existing water treatment system during average and wet years.  

In June 2012, Colorado Gov. John Hickenlooper sent a letter to President Obama requesting that the president use his authority to coordinate federal agencies to bring an expeditious conclusion to the federal permitting process for the project.  The Corps, Environmental Protection Agency, Federal Energy Regulatory Commission, Colorado Department of Public Health and Environment Water Quality Division, Colorado Department of Natural Resources, and Grand County have worked together to meet Federal requirements for the Final EIS while satisfying state and local concerns.
