PURPOSE OF PUBLIC NOTICE The US Environmental Protection Agency, Region 9 (EPA or Agency) is extending the public comment period on its proposal to issue a Class V Underground Injection Control (UIC) renewal permit (Draft Permit) for Puna Geothermal Venture (PGV). Additionally, EPA is announcing a virtual public hearing where the public can provide oral testimony on the Draft Permit for PGV. Details of the public hearing and instructions on how to participate in the hearing are provided below. BACKGROUND PGV owns and operates a geothermal electrical power generating facility at 14-3860 Kapoho-Pahoa Road in Pahoa, Hawai’i (PGV Facility). The proposed action, to issue the Permit, would authorize for ten years: the continued operation of five existing injection wells at the PGV Facility (Existing Wells); and, the conversion of up to eleven (11) proposed geothermal production wells to injection wells, for the continued operation and development of PGV’s geothermal field to generate electrical power (Proposed Wells). The Existing Wells are currently permitted to inject non-hazardous fluids that are byproducts of geothermal power production under an existing EPA-issued UIC permit. The Proposed Wells would be permitted for the conversion of geothermal production wells to injection wells, contingent upon PGV meeting certain conditions of the Permit. Current production wells at the PGV Facility are authorized and regulated by a permit issued by the Hawai’i Department of Land and Natural Resources. After completing technical review of all submitted information, EPA made a preliminary determination that the activities proposed under the Draft Permit are protective of underground sources of drinking water, as required by the Safe Drinking Water Act. EPA announced a 30-day public comment period, which ended on July 24, 2020, seeking input from the public on the Draft Permit. During this period, EPA received a significant number of requests for a public hearing. Due to public interest, EPA is extending the public comment period and scheduling a public hearing pursuant to 40 CFR 124.10 and 124.12. VIRTUAL PUBLIC HEARING To protect the public’s health during the Coronavirus Disease 2019 (COVID 19) pandemic, the public hearing will be conducted virtually. The virtual public hearing for those who wish to provide oral testimony is scheduled for the evening of October 7, 2020 from 5:00 pm until 8:00 pm Hawai’i time.
