Start Preamble

AGENCY:

Environmental Protection Agency.

ACTION:

Notice of denial of petition.

SUMMARY:

This action notifies the public that the Agency received a petition pursuant to section 612(d) of the Clean Air Act, under the Significant New Alternatives Policy (SNAP) Program, and that EPA is denying the petition. SNAP implements section 612 of the Clean Air Act Amendments of 1990, which requires EPA to evaluate substitutes for ozone-depleting substances (ODSs) and to regulate the use of substitutes where other alternatives exist that reduce overall risk to human health and the environment. Through these evaluations, EPA generates lists of acceptable and unacceptable substitutes for each of the major industrial use sectors that use ODSs, including the refrigeration and air-conditioning sector. OZ Technology, Inc. submitted HC-12a, previously referenced as Hydrocarbon Blend B, as a CFC-12 substitute in a variety of end-uses on July 19, 1994. In a June 13, 1995 final SNAP rulemaking (60 FR 31092), EPA found the use of HC-12a unacceptable as a substitute for CFC-12 in all end-uses other than industrial process refrigeration. This determination was based on a lack of adequate data demonstrating that HC-12a could be used safely in these end-uses; the most recent petition from OZ does not provide any additional information to address this issue. In addition, numerous other acceptable alternatives to ODSs exist in these end-uses.

EFFECTIVE DATE:

March 2, 2004.

On July 8, 2003, OZ petitioned EPA for the fourth time, once again requesting that EPA remove HC-12a from the unacceptable list and add it to the acceptable list as an ODS substitute in all refrigeration and air-conditioning end-uses, except the industrial process refrigeration end-use, where EPA has already found the use of HC-12a as acceptable. The petition is in Air Docket A-91-42, file number VI-D-306. On January 14, 2004, EPA notified the company that it has denied the petition on the basis that the information included in the petition did not adequately address safety issues regarding the use of HC-12a as a CFC-12 substitute in the subject end-uses. The denial and the accompanying documentation are in Air Docket A-91-42, file number VI-C-31. This Notice Start Printed Page 9755publicizes EPA's denial of the fourth petition.
