Sec. 61.62  Emission standard for ethylene dichloride plants.

    (a) Ethylene dichloride purification. The concentration of vinyl 
chloride in each exhaust gas stream from any equipment used in ethylene 
dichloride 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.
    (b) Oxychlorination reactor. Except as provided in Sec. 61.65(a), 
emissions of vinyl chloride to the atmosphere from each oxychlorination 
reactor are not to exceed 0.2 g/kg (0.4 lb/ton) (average for 3-hour 
period) of the 100 percent ethylene dichloride product from the 
oxychlorination process.
