(b) Any owner or operator of a synthetic organic chemical manufacturing facility where such chemicals are first manufactured on or after the effective date of this Part is required to demonstrate compliance with this Part upon start-up.

(c) Components subject to Federal regulations which require either an equal or more stringent leak detection and repair program (i.e., equivalent or lower definition of leak and equivalent or more frequent monitoring requirements), or equal or more stringent equipment specifications, are deemed to be in compliance with the provisions of this Part contingent on the source owner or operator complying with such Federal regulations.

The department is cognizant of pending National Emission Standards for Hazardous Air Pollutants which regulate process unit components to control fugitive emissions of volatile hazardous air pollutants. These standards would regulate many of the same components as Part 236. Where the Federal standards are adopted to be more stringent than those of Part 236, the department will accept compliance with the Federal standards in lieu of compliance with this Part, contingent on the adoption and implementation of the Federal standards.
