Protection of Stratospheric Ozone

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 amended Clean 
Air Act of 1990, which requires EPA to evaluate substitutes for ozone-
depleting substances (ODS) 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 ODS, including the refrigeration and 
air-conditioning sector.
    OZ Technology, Inc. submitted Hydrocarbon Blend B, or HC-
12a, 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 Hydrocarbon Blend B 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 Hydrocarbon Blend B could be used safely in these end-uses. In 
addition, numerous other acceptable alternatives to ODS exist in these

    On May 1, 1998, OZ Technology, Inc. petitioned EPA for the third

Blend B from the unacceptable list and add it to the acceptable list as 
a substitute used in all

Air Docket A-91-42, file number VI-D-229. On November 13, 1998, EPA 
denied the petition on the basis that the information included in the 
petition did not adequately address safety issues regarding the use of 
Hydrocarbon Blend B as a CFC-12 substitute in new equipment. The denial 
and the accompanying documentation are in Air Docket A-91-42, file
