ENVIRONMENTAL PROTECTION AGENCY
[FRL-8318-4]
Underground Injection Control Program Petition for Exemption From
Hazardous Waste Disposal Restrictions to the Resource Conservation and
Recovery Act Class I Hazardous Waste Injection Occidental Chemical
Corporation, Wichita, KS
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of final decision on petition.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that an exemption to the land disposal
restrictions under the 1984 Hazardous and Solid Waste Amendments to the
Resource Conservation and Recovery Act has been granted to Occidental
Chemical Corporation (Occidental) for a Class I injection well,
identified as Well Number 10, located at Wichita, Kansas. This
injection well, is being added to an existing group of five hazardous
waste injection wells which EPA had approved in 1990. As required by
title 40 Code of Federal Regulations (CFR) part 148, Occidental has
adequately demonstrated to the satisfaction of the Environmental
Protection Agency by petition and supporting documentation that, to a
reasonable degree of certainty, there will be no migration of hazardous
waste out of the designated injection zone for as long as the waste
remains hazardous. This time frame is defined by 40 CFR 148.20 as
10,000 years. This final decision allows the underground injection by
Occidental of the specific restricted waste, identified in the
petition, into injection well Number 10 at the Wichita, Kansas
facility, for as long as the basis for granting an approval of the
petition remains valid, under provisions of 40 CFR 148.24. For the
purpose of the required demonstration of no-migration of hazardous
waste out of the injection zone over a 10,000 year period, modeling and
projections were based on an operational lifetime projection date of
December 31, 2020. Therefore, on or by the closing date of the
aforementioned operation period, the owner/operator will be required to
obtain an exemption re-issuance from EPA. Included in this approval is
the stipulation that Occidental acquires and continues to maintain an
approved permit from the Kansas Department of Health and Environment.
As required by 40 CFR 124.10, a public notice was issued on February
26, 2007. In addition to having solicited written comments regarding
the Agency's proposed approval, EPA also announced that a formal public
hearing would be held if there was a significant degree of public
interest, but no interest was expressed, hence no formal public hearing
was conducted; however, EPA held an informal Public Availability
Session on March 13, 2007, at the Sedgwick County Extension Office in
Wichita, Kansas, in order to provide the public with an opportunity to
meet with Federal, State, and company officials and ask questions
regarding the petition. The public comment period ended on April 11,
2007. All comments were addressed and considered in the final decision.
This decision constitutes final Agency action and there is no
administrative appeal process that can be applied to a final petition
decision.
DATES: Effective Date: This action is effective as of May 2, 2007.
ADDRESSES: Copies of the petition and all pertinent information
relating thereto, including the Agency's response to comments, are on
file at the following location: Environmental Protection Agency, Region
7, Regional Records Center, 901 N. 5th St., Kansas City, KS 66101.
