Draft EIS released for Denver Water's Moffat Collection System

Posted: 11/02/2009
By: Nathan Fey

The US Army Corps of Engineers, Omaha District, (Corps) is preparing an Environmental Impact Statement (EIS) to evaluate the environmental consequences of the proposed Moffat Collection System Project (Moffat Project), submitted by the Denver Water Department (Denver Water) Denver, Colorado.

To meet their projected future water needs, Denver Water proposes to develop 18,000 acre-feet per year of new, annual firm yield water delivered to the Moffat Treatment Plant and raw water customers upstream of the Moffat Treatment Plant pursuant to Denver Water Board’s commitment to its customers.  Denver Water's preferred project to meet this need is to raise Gross Reservoir in Boulder County to store an additional 72,000 acre-feet of water.

In addition to Denver Water's preferred project, the Corps' EIS will evaluate over 300 other options to meet Denver Water's need for water, including several other incremental raises to Gross Reservoir, a new reservoir on Leyden Creek in Jefferson County, additional water stored in local gravel pits and in local underground aquifers, advanced water treatment, and purchase of existing agricultural water rights.


The Draft EIS was released on October 30, 2009 to analyze the direct, indirect, and cumulative effects of the proposal, to provide decision-makers and the public with information pertaining to the Proposed Action and alternatives, and to disclose environmental impacts and identify mitigation measures to reduce impacts.   The Corps, Omaha District, Regulatory Branch is the lead federal agency responsible for the Draft EIS and information contained in it will serve as the basis for a decision regarding issuance of a Section 404 permit.  It also provides information for federal, state, and local agencies having jurisdictional responsibility for affected resources.  The U.S. Environmental Protection Agency Region 8 and Federal Energy Regulatory Commission participated as cooperating agencies, and Grand County participated as a consulting agency in the formulation of the Draft EIS.
