Mr. Speaker, this month, the Department of Interior and the California Department of Water Resources announced an increase in water allocation to farmers in the San Joaquin Valley. Our efforts to press the administration for more water is producing results and is already flowing to the San Joaquin Valley and Southern California.
But our fight for our valley's jobs and economy is far from over. Regulations that restrict the flow of water to our valley must be revised. I am pleased that the administration has announced its intention to revise and integrate the two biological opinions that single out valley agriculture for degrading the delta when we know that this simply is not true. All factors affecting the health of the Sacramento/San Joaquin Delta must be taken into account as we move forward, including predation of invasive species and other water quality factors.
I would like to submit a letter for the Record from the Central Valley Regional Water Control Board that confirms the need to address water quality issues. This includes the dumping of pollutants, such as ammonia and toxic urban run-off and the impact of power plants on the ecosystem, among other things. We will win this fight, and common sense will prevail. Recognizing all of the factors impacting the delta will allow more water to flow to the valley and the rest of California.
Congress of the United States,
Washington, DC, June 9, 2010.
Charles R. Hoppin,
Chair, State Water Resources Control Board, Sacramento, CA.
Katherine Hart,
Chair, Central Valley Regional Water Quality Control Board,
Rancho Cordova, CA.
Dear Chairs Hoppin and Hart: We are writing to request that
the State Water Resources Control Board and the Central
Valley Regional Water Quality Control Board take immediate
action to address ammonia discharges from wastewater
facilities into the Sacramento-San Joaquin Delta (Delta).
As you are aware, we have long held that the single focus
of regulatory agencies on water exports is misguided in that
it overlooks other key stressors that contribute to the
decline of fisheries in the Delta. The effect of this single
focus is to punish farmers, farmworkers and communities in
the San Joaquin Valley at a tremendous impact to state's
economy, and in the end the fish are no better off.
Two recent studies point to Sacramento's wastewater as a
significant cause behind the declining fish populations in
the Delta. One study, authored by Patricia Glibert of the
University of Maryland, concludes that the Delta's
environmental problems are more likely tied to wastewater
pollution than to water diversions, indicating that increased
ammonia in Sacramento wastewater has disrupted algae
production in the Delta, which rippled up the food chain to
compromise fish species. Another study by Inge Werner, a
toxicologist at UC Davis, concluded that threatened Delta
smelt may be harmed by exposure to ammonia at levels below
federal limits and that longterm exposure could reduce smelt
growth and feeding activity, which would ultimately affect
their breeding success.
These studies cry out for immediate action by the
responsible regulatory agencies. We understand that the
Regional Board has renewed Sacramento Regional County
Sanitation District's wastewater discharge permit annually
without substantive review since it expired in 2005. As the
single largest wastewater discharger in the Delta, it is
crucial that the Regional Board conducts a full and immediate
review of the District's permit and that the Regional Board
conditions any renewal upon upgrading the sewage treatment
system to a tertiary system. Tertiary systems have been
installed throughout San Joaquin Valley communities as a
result of regulations imposed by the Regional Board in order
to improve water quality. We find it incongruous that the
very board that has imposed tertiary treatment requirements
on communities in the San Joaquin Valley, including Stockton,
Modesto, Turlock and Fresno, has failed to impose similar
requirements on the Sacramento District.
These studies confirm that ammonia wastewater discharges
are a large part of the problem in the Delta. Reducing
ammonia discharges needs to be part of the solution, along
with the other key factors that are contributing to the
environmental decline in the Delta. We call upon the Regional
Board to take immediate action to correct this problem.
Sincerely,
Jim Costa,
Member of Congress.
