Land Ban Exemption Granted to LTV Steel
(FRL-3819-2)Underground Injection Control Program; Hazardous Waste Disposal Injection Restrictions Petition for Exemption--Class I Hazardous Waste Injection LTV Steel Co., Hennepin Works, Hennepin, IL
AGENCY: Environmental Protection Agency.
ACTION: Notice of final decision on petition.
---------------------------------------------------------------
SUMMARY: Notice is hereby given by the United States Environmental Protectio Agency (USEPA) that an exemption to the land disposal restrictions under the 1984 Hazardous and Solid Waste Amendments (HSWA) to the Resource Conservation and Recovery Act (RCRA) has been granted to LTV Steel Co. (LTV) of Cleveland, Ohio, for its Class I injection well located in Hennepin, Illinois. As required by 40 CFR part 148, LTV has demonstrated, with a reasonable degree of certainty, that there will be no migration of hazardous constituents from the injection zone for as long as the waste remains hazardous. This final decision allows the continued underground injection by LTV of a specific restricted waste, waste pickle liquor, (code K062 under 40 CFR part 261), into one Class I hazardous waste injection well specifically identified as Waste Pickle Liquor Well No. 1, at the Hennepin facility. This decision constitutes a final USEPA action for which there is no Administrative Appeal.
Background
LTV submitted a petition for exemption from the land disposal restrictions of hazardous waste on September 29, 1988. USEPA personnel reviewed all data pertaining to the petition, including, but not limited to, well construction, regional and local geology, seismic activity, penetrations of the confining zone, and the mathematical models. The USEPA has determined that the geological setting at the site as well as the construction and operation of the well are adequate to prevent fluid migration out of the injection zone within 10,000 years, as required under 40 CFR part 148. The injection zone at this site is the Mt. Simon Formation and the Lombard and Elmhurst Members of the Eau Claire Formation, and the immediate confining zone is the Proviso Member of the Eau Claire Foundation, at a depth of 2705 feet to 2902 feet below ground level. The confining zone is separated from the lowermost underground source of drinking water (at a depth of 2535 feet below ground level) by a sequence of permeable and less permeable sedimentary rocks, which provide additional protection from fluid migration into drinking water sources. A fact sheet containing a more complete summary of the proposed decision was published in the Federal Register on May 7, 1990.
A public notice was issued on May 1, 1990, pursuant to 40 CFR 124.10, and a public hearing was subsequently held in Hennepin on May 31, 1990. The public comment period expired on June 15, 1990. All comments that were received have been considered in making the final decision. A responsiveness summary has been mailed to all commentors and included as part of the Administrative Record relating to this decision.
Condition
As a condition of this exemption, LTV must meet the following conditions:
(1) The monthly average injection rate must not exceed 153 gallons per minute, consistent with well design capacity;
(2) The petitioner shall comply with the groundwater monitoring plan found in the Administrative Record for this decision. A detailed drilling, testing, and operational plan for the monitoring well(s) shall be submitted to the Director within 60 days of this final decision pursuant to 40 CFR part 148; and
(3) LTV must be in full compliance with all conditions of its permit. Other conditions relating to the exemption may be found in 40 CFR parts 148.23 and 148.24.
DATE: This action is effective as of July 24, 1990.
