Sec. 61.63  Emission standard for vinyl chloride plants.

    An owner or operator of a vinyl chloride plant shall comply with the 
requirements of this section and Sec. 61.65.
    (a) Vinyl chloride formation and purification: The concentration of 
vinyl chloride in each exhaust gas stream from any equipment used in 
vinyl chloride formation and/or purification is not to exceed 10 ppm 
(average for 3-hour period), except as provided in Sec. 61.65(a). This 
requirement does not preclude combining of exhaust gas streams provided 
the combined steam is ducted through a control system from which the 
concentration of vinyl chloride in the exhaust gases does not exceed 10 
ppm, or equivalent as provided in Sec. 61.66. This requirement does not 
apply to equipment that has been opened, is out of operation, and met 
the requirement in Sec. 61.65(b)(6)(i) before being opened.
