Before October 1, 2014, the San Francisco Bay Regional Water Quality Control Board may authorize a voluntary pilot project for the purposes of investigating potential water quality impacts and water supply benefits associated with maximizing the supplementation of agricultural irrigation impoundments with disinfected tertiary treated recycled water, if the San Francisco Bay Regional Water Quality Control Board finds that the proposed pilot project satisfies all of the following criteria:(a) The pilot project is consistent with any applicable waste discharge requirements, including, but not limited to, having a NPDES permit, pursuant to Section 1251 et seq. of Title 33 of the United
States Code for discharges covered by the pilot project, and performs all tasks as needed to obtain the NPDES permit, including, but not limited to, preproject modeling and habitat evaluations, and other data collection efforts.
(b) The pilot project shall measure, analyze, and report water quality data collected upstream and downstream of agricultural irrigation impoundments before, during, and following at least five storm events that result in the release of commingled disinfected tertiary recycled water and surface water runoff from up to four agricultural irrigation impoundments into waters of the state.
(c) The pilot project includes a process for selecting up to four existing agricultural irrigation impoundments within the Counties of Napa and Sonoma for the purposes of the pilot
project. A selected agricultural irrigation impoundment shall meet all of the following requirements:
(1) Have existed prior to January 1, 2013.
(2) Be not more than 200 acre-feet in volume.
(3) Be within a primarily agricultural region that currently receives disinfected tertiary treated recycled water, consistent with any waste discharge requirements, for the purposes of discharge, agricultural irrigation, and ecosystem restoration.
(d) The pilot project is designed to measure, analyze, and report at least the following water quality and environmental parameters:
(1) Constituents addressed by
total maximum daily loads completed for the San Francisco Bay, Napa River watershed, and the Sonoma Creek watershed, including, but not limited to, mercury, Polychlorinated biphenyls, pathogens, nutrients, and selenium.
(2) Constituents associated with municipal recycled water, including, but not limited to, total suspended solids, total ammonia, copper, pH, temperature, biochemical oxygen demand, total chlorine residual, copper, nickel, and cyanide.
(e) The pilot project incorporates a stakeholder advisory group to review and provide input on pilot project design, implementation, and data analysis, and consists of the following membership:
(1) One representative from each of three nongovernmental organizations
focused on San Francisco Bay region water quality and habitat issues.
(2) One representative from a regional agricultural organization.
(3) Two private landowners.
(4) A representative from the Sonoma Valley County Sanitation District.
(5) A representative from the Napa Sanitation District.
(6) A representative from the Sonoma County Water Agency.
(7) A representative from the San Francisco Bay Regional Water Quality Control Board.
(f) The pilot project will include an analysis of
local water management implications associated with increasing the use of recycled water for agricultural irrigation impoundments, including, but not limited to, reduced reliance on surface and groundwater resources, reduced ecosystem conflicts, and increased local resilience to climate change.
(g) The project proponents have identified and secured funding for all costs associated with the development and implementation of the pilot project.
