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

period) of the 100 percent ethylene dichloride product from the 

oxychlorination process.
