ENVIRONMENTAL PROTECTION AGENCY

[FRL-6198-5]


Notice of Final Decision to Grant Waste Management of Ohio, Inc. 
a Modification of an Exemption from the Land Disposal Restrictions of 
the Hazardous and Solid Waste Amendments of 1984 Regarding Injection of 
Hazardous Wastes

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of final decision on a request to modify an exemption 
from the Hazardous and Solid Waste Amendments of the Resource 
Conservation and Recovery Act.

-----------------------------------------------------------------------

SUMMARY: Notice is hereby given by the Environmental Protection Agency 
(EPA or Agency) that modification of an exemption to the land disposal 
restrictions under the 1984 Hazardous and Solid Waste Amendments to the 
Resource Conservation and Recovery Act (RCRA) has been granted to Waste 
Management of Ohio, Inc. (WMO) of Oakbrook, Illinois. This modification 
allows WMO to continue to inject four (4) RCRA-regulated hazardous 
wastes which will be banned from land disposal on February 8, 1999, as 
a result of regulations promulgated in the Federal Register (FR) on 
August 6, 1998 (63 FR 42110), into four Class I injection wells at the 
Vickery, Ohio facility. As required by 40 CFR part 148, WMO has 
demonstrated, to a reasonable degree of certainty, that there will be 
no migration of hazardous constituents from the injection zone utilized 
by WMO's waste disposal facility located near Vickery, Ohio, for as 
long as the newly exempted waste remains hazardous. This decision 
constitutes a final Agency action for which there is no administrative 
appeal.

DATES: This action is effective as of February 8, 1999.

FOR FURTHER INFORMATION CONTACT: Harlan Gerrish, Lead Petition 
Reviewer, USEPA, Region 5, telephone (312) 886-2939. Copies of the 
petition and all pertinent information relating thereto are on file and 
are part of the Administrative Record. It is recommended that you 
contact the lead reviewer prior to reviewing the Administrative record.

SUPPLEMENTARY INFORMATION:

I. Background

    Chemical Waste Management (CWM), the predecessor of WMO, submitted 
a petition for an exemption from the restrictions on land disposal of 
hazardous wastes on January 19, 1988. Revised documents were received 
on December 4, 1989, and several supplemental submittals were 
subsequently made. The exemption was granted on August 7, 1990. On 
September 12, 1994, CWM submitted a petition to modify the exemption to 
include wastes bearing 23 additional RCRA wastes codes. Region 5 
reviewed documents supporting the request and granted the modification 
of the exemption on May 16, 1995. A notice of the modification appeared 
on June 5, 1995, at 60 FR 29592 et seq. On April 9, 1996, CWM submitted 
a petition to again modify the exemption to allow 91 additional RCRA 
waste codes. Region 5 reviewed documents supporting the request and 
granted the modification on the exemption on June 24, 1996. A notice of 
the modification appeared on July 15, 1996, at 61 FR 36880 et seq. 
Again on May 13, 1997, CWM submitted a request to add 11 waste codes to 
the list. Region 5 reviewed the evidence submitted by CWM and granted 
the request. Notice of the approval appeared on August 12, 1997 (63 FR 
43109). On August 28, 1998, WMO requested that two additional wastes 
codes be approved for injection. This proposed approval of this request 
is pending as a result of need for public comment on the decision.
    The rule promulgated on August 6, 1998, bans K169, K170, K171, and 
K172 from injection after February 8, 1999, unless WMO's exemption is 
modified to allow injection of those wastes. After review of the 
material submitted, the EPA has determined, as required by 40 CFR 
148.20(f), that there is a reasonable degree of certainty that the 
hazardous constituents contained in the wastes bearing the codes to be 
banned will behave hydraulically and chemically like wastes for which 
WMO was granted its original exemption and will not migrate from the 
injection zone in hazardous concentrations within 10,000 years. The 
injection zone is the Mt. Simon Sandstone and the Rome, Conasauga, 
Kerbel, and Knox Formations. The confining zone is comprised of the 
Wells Creek and Black River Formations.

II. Conditions

    General conditions of this exemption are found at 40 CFR part 148. 
The exemption granted to WMO on August 7, 1990, included a number of 
specific conditions. Conditions numbered (1), (2), (3), (4), and (9) 
remain in force. Monitoring under condition 5, which called for 
construction and operation of a deep monitoring well, will continue 
through the life of the facility. Conditions numbered (5), (6), (7), 
and (8) have been satisfied. The results of the work carried out under 
these conditions confirms that the model used to simulate fluid 
movement within the injection zone for the next 10,000 years is valid 
and results of the simulation bound the region of the injection zone 
within which the waste will be contained.
