National Emission Standards for Hazardous Air Pollutants for 
Source Categories: Organic Hazardous Air Pollutants From the Synthetic 
Organic Chemical Manufacturing Industry and Other Processes Subject to 
the Negotiated Regulation for Equipment Leaks; Clarifications

AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule: Amendments.




SUMMARY: On April 10, 1995, the EPA proposed amendments to certain 
portions of the ``National Emission Standards for Hazardous Air 
Pollutants from the Synthetic Organic Chemical Manufacturing Industry 
and Other Processes Subject to the Negotiated Regulation for Equipment 
Leaks'' (collectively known as the ``hazardous organic NESHAP'' or the 
``HON''). This action announces the EPA's final decisions on those 
proposed amendments.

    The rule is being revised to remove three compounds (glycerol tri-
(polyoxypropylene)ether, polyethylene glycol, and polypropylene glycol) 
from the list of chemical production processes regulated by the HON. 
The production of these compounds is also included in the source 
category ``Polyether Polyols Production'' and will be regulated by that 
national emission standards for hazardous air pollutants (NESHAP). The 
equipment leak requirements in the rule are also being revised to 
clarify the intent of certain provisions, to correct oversights, and to 
simplify demonstration of compliance with the regulation. These changes 
are being made to ensure that the rule is implemented as intended.

EFFECTIVE DATE: June 20, 1996.
