Water Right Permit 10478 Time Extension Project

The Mokelumne River is the primary source of water for more than 1.3 million residents of the East Bay. EBMUD's right to provide this water is based on the terms of two state water rights: a license and a permit per the State Water Resources Control Board, who issues permits and licenses to divert water.

In 1956, the State Water Resources Control Board issued water right Permit 10478 to EBMUD to support East Bay water needs and allow the additional diversion of 125 million gallons per day of water from the Mokelumne River to the East Bay. In 1964, EBMUD built Camanche Reservoir to store and use water diverted under Permit 10478. This water supplements EBMUD's senior water right which was issued in 1926 and licensed in 1981.

The term of the permit required that water be fully beneficially used by December 1, 2000. Long term studies show that water available under the permit will be needed in the future as water demand grows. In November 2000, EBMUD requested a time extension of 40 years to year 2040 to continue the terms of existing Permit 10478. In November 2008, EBMUD issued a "Notice of Preparation, EBMUD Camanche Permit Extension Environmental Impact Report." On September 30, 2013, the East Bay Municipal Utility District (EBMUD) published the Permit 10478 Time Extension Project Draft EIR for public review.   

The Notice of Availability was posted on the project website and filed at the offices of the Alameda, Contra Costa, Amador, Calaveras, San Joaquin and Stanislaus County Clerks.  Printed copies of the Draft EIR were available for public review at several libraries in the cities of Oakland, Lodi, Stockton, Jackson and San Andreas.  In addition, four public meetings were held to receive public comments on the Draft EIR.  The original 45-day public review and comment period, which began on October 3, 2013 and was scheduled to close on November 18, 2013, was extended to and closed on January 10, 2014.
