25143.6. Spent brine solutions: exemptions. (a) Spent brine solutions that are byproducts from the treatment of groundwater to meet California drinking water standards are exempt from the requirements of this chapter if all of the following conditions are met:
(1) The treatment of these spent brine solutions by dewatering via a closed piping system to lined surface impoundments is specifically approved by the applicable regional water quality control board.
(2) The spent brine solutions are transferred for dewatering via a closed piping system to lined surface impoundments regulated by the California regional water quality control boards.
(3) The spent brine solutions are treated, prior to transfer to lined surface impoundments, with a technology that renders the spent brine solutions nonhazardous for all contaminants except selenium.
(4) Mitigation measures, which shall be approved by the Department of Fish and Wildlife, are used to prevent birds from coming into contact with spent brine solutions in lined surface impoundments containing hazardous levels of selenium.
(b) If spent brine solution that is exempt pursuant to subdivision (a) is relocated to an elevated location inside a lined surface impoundment for further dewatering, the waste from that spent brine solution shall be removed from the lined surface impoundment while it still contains sufficient moisture to prevent wind dispersion.
(c) Waste from spent brine solutions exempt pursuant to subdivision (a) shall be deemed generated at the time of removal from a lined surface impoundment and shall be managed pursuant to the requirements of this chapter if determined to be a hazardous waste.
(d) Operators of surface impoundments used for the treatment of spent brine solutions shall maintain financial assurances consistent with the requirements of this chapter.
(e) Untreated spent brine solutions shall be managed in accordance with this chapter.
