The United States Environmental Protection Agency, Region 9, Groundwater Protection Section, 75 Hawthorne Street, San Francisco, CA 94105 (EPA) is providing an opportunity for the public to comment on its proposal to issue a renewal Class I Non-hazardous Underground Injection Control (UIC) Permit for CXA La Paloma, LLC (CXA or “Permittee”). CXA owns and operates a power plant (“La Paloma Generating Plant” or LPGP) including one (1) existing injection well WD-3, and two (2) proposed injection wells, WD-6 and WD-7, located at 1760 West Skyline Road near McKittrick, California.
The Class I UIC Permit, if issued, would authorize continued operation of WD-3 for ten (10) years, and construction and operation of WD-6 and WD-7 during the same period of time.
Injected non-hazardous fluids, detailed in the Permit, consist primarily of cooling tower blowdown from the power plant cooling process with lesser volumes of boiler and evaporative cooler blowdown, wash water, filter backwash, equipment drains, and stormwater from equipment containment areas at LPGP.
The current injection well is designed to inject wastewater into the Upper Miocene Olig Sand Member of the Reef Ridge Formation at the injection interval of 4,381 feet to 5,268 feet below ground surface. After completing a thorough technical review of all information submitted by CXA in its permit application, including the proposed well construction, operational standards, monitoring requirements, and existing geologic setting, EPA believes the activities allowed under the Draft Class I UIC Permit (“Draft Permit”) are protective of underground sources of drinking water as required by the Safe Drinking Water Act (SDWA).
EPA has made a preliminary determination to issue a Class I UIC permit to CXA pending this public notice. This action is being taken as provided by Part C of the SDWA and pursuant to Title 40 of the Code of Federal Regulations (CFR) Parts 124, 144, 146, and 147.
All data submitted by the applicant is available as part of the administrative record for the Draft Permit. This Notice, EPA’s Fact Sheet, the Draft Permit, CXA’s permit application, and other supporting documents are available for public review online at www.regulations.gov under docket number EPA-R09-OW-2021-0605.

Final Permit Decision and Appeals Process

EPA will post its response to comments document on www.regulations.gov under docket number EPA-R09-OW-2021-0605. The response to comments will contain a response to all comments on the Draft Permit, EPA’s final permitting decision, any permit conditions that are changed and the reasons for the changes, and procedures for appealing the decision. The final decision shall be to either issue or deny the Permit. The final decision shall become effective no sooner than thirty (30) days after the service of the notice of decision. Within thirty (30) days after the final permit decision has been issued, any person who filed comments on the Draft Permit, participated in any public hearing on this matter, or takes issue with any changes in the Draft Permit, may petition the Environmental Appeals Board to review any condition of the permit decision. Commenters are referred to 40 CFR § 124.19 for procedural requirements of the permit appeal process. If no comments request a change in the Draft Permit, EPA’s final decision shall become effective immediately upon issuance unless a later date is specified in the notice of final decision.
