This paragraph does apply to water which is used to displace vinyl chloride from equipment before it is opened to the atmosphere in accordance with s. NR 449.06 (1) (b) or par. (f), but does not apply to water which is used to wash out equipment after the equipment has already been opened to the atmosphere in accordance with s. NR 449.06 (1) (b) or par. (f).
NR 449.07(2)(i)2. 2. Any vinyl chloride removed from the inprocess wastewater in accordance with subd. 1. shall be ducted through a control system from which the concentration of vinyl chloride in the exhaust gases may not exceed 10 parts per million, or equivalent as provided in s. NR 449.08
