SUPPLEMENTARY INFORMATION:

I. Background

The existing petition allows for the subsurface disposal by OxyChem of specific restricted wastes via Class I hazardous waste injection wells at OxyChem's Wichita, Kansas facility and was approved by EPA with an effective date of October 24, 2008. In its renewal application, OxyChem requested that the petition reissuance include six Class I wells which would cover the five existing Class I injection wells in addition to a Class I well yet to be drilled. This action results in no change to the total volume of fluids to be injected. This final decision allows the underground injection by OxyChem of the specific wastes identified in the petition reissuance into injection wells Number 3, 8, 9 10, 11 and proposed number 14 at the Wichita, Kansas facility through January 2, 2040, unless EPA moves to terminate this exemption pursuant to 40 CFR 148.24. Included in this approval is the stipulation that OxyChem acquires and continues to maintain an approved permit from the Kansas Department of Health and Environment for all Class I injection wells. A public notice concerning the Agency's proposed action was issued on October 15, 2021, and the public comment period closed on December 3, 2021. In addition to soliciting written comments regarding the Agency's proposed approval, EPA conducted a virtual public availability session and a virtual formal public hearing on November 18, 2021. No comments were received during the comment period. This decision constitutes a final Agency action. There is no further administrative process to appeal this decision. This decision may be reviewed/appealed in compliance with the Administrative Procedure Act.
