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

On October 24 and 28, 1994, EPA proposed amendments to certain aspects 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'' 59 FR 19402 (April 22, 1994) and 59 FR 29196 (June 6, 1994) (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 provide a deferral of HON requirements for source owners or operators who wish to make an area source certification and to establish minimum documentation requirements. This action is being taken because EPA believes that in view of current circumstances the requirements of the rule should not be imposed on sources that are likely to be designated as area sources in the near future. The rule is also being revised to extend the compliance date for certain compressors and for surge control vessels and bottoms receivers to allow the time necessary for installation of controls. The applicability of control requirements for surge control vessels and bottoms receivers is also being revised to reduce confusion over the rule.
