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.

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 United States Environmental 
Protection Agency (USEPA 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 inject two (2) RCRA-regulated 
hazardous wastes which will be banned from land disposal on November 4, 
1998, as a result of regulations promulgated in the Federal Register 
(FR) on May 4, 1998 (63 FR 24596) and subsequently corrected on June 
29, 1998 (63 FR 35147), 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.

BACKGROUND: Chemical Waste Management (CWM), the parent company 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, in response to the Land Disposal Restrictions 
Rule published in the Federal Register at 63 FR 24596 et seq. on May 4, 
1998, which set a ban date of November 4, 1998, for a number of 
hazardous waste codes, WMO submitted a request to add two (2) 
additional RCRA waste codes, K140 and U408, to its exemption. The 
diffusion rate of the underlying chemical, 2,4,6-Tribromophenol (2,4,6-
TBP), represented by the codes to be banned has not yet been considered 
by Region 5. Therefore, WMO has submitted information demonstrating 
that 2,4,6-TBP will not diffuse so rapidly as the chloride ion.
    The newly-promulgated rule bans codes K140 and U408 from deep 
injection after November 4, 1998, unless WMO makes a no-migration 
demonstration. WMO made a no-migration demonstration in 1990. After 
careful review of the material submitted, the USEPA has determined, as 
required by 40 CFR 148.20(f), that there is a reasonable degree of 
certainty that waste streams containing 2,4,6-TBP 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.
    As a result of this action, WMO may continue to inject wastes 
bearing the codes K140 and U408 after wastes denoted by these codes are 
banned from land disposal on November 4, 1998. These waste codes are 
added to the waste codes which have been previously exempted. The 
current listing of all codes approved for injection follows.

    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

valid and results of the simulation bound the region of the injection 
zone within which the waste will be contained.
