Proposed Amendments to the* Notion;'.! Emission Standard for Vinyl Ciil ori tie EPA'k proposed amendments to the National Kiris si on Standard for Vinyl Chloride, 40 C.K.K. Part 61 Subpart K, shall embody the following concepts: A. The ultimate goal of zero vinvl chloride emissions and EPA1s intention to reduce emissions toward this limit will be expressed. B, The 10 ppm limitation under, .the existing standard will be propose;] to be tightened to 5 .ppm .based on F.PA 1 s_. judgment that technology required by._the existing standard can achieve^ the lower standard, with the following additiona 1 proposec^ fejitures: 1. The 5 ppm standard will be applied to existing sources no later than three years from promul gation of the amendments; //-- / 9 (a) Existing sources may institute a_ review procedure before EPA if the 5 ppm standard cannot he met on the~expe'ctfed compliance date; (i) the review procedure may be initiated by the source notifying EPA in 'writing no later than one year from the expected compliance date that compliance will not take place; the notification must contain written documentation why compliance is impossible, whet interim steps the source will take to reach the 5 ppm standard, and a suggested compliance schedule for reaching the 5 ppm goal; (ii) with!'-' thirty days, EPA will confer with the source to consider any oral testimony; the public will be invited to testify cr submit written documentation at the conference; UCC 102816 (iii ) within sixty days after the conference, Ki'A will (a) deny the source's request or (b) fashion a schedule for the source's compliance with the 5 ppm standard, accompanied by interim emission Limitations if warranted; 2, New sources will bo subject to the 5 ppm standard no later than six months from the^j^romulgabion of the amendments, but no procedure for relivef from this deadline (such as that for existing sources) will be proposed . 6 - / - ~7 S' C. Emission limitations for the oxychlorinatio11 jrrpeess . and the stripping of dispersion resins, requirinjj more control of these procedures than the existing standard, will be proposed for new sources. 7 D. It will be proposed that existing facilities 'will not be permitted to ermand unless increased vinyl chloride emissions are offset bv equivalent re evic tions in vinyl chloride emissions at the expanding facility. E. EPA will undert; ; Ke full-scale review of Subnart E of 40 C.F.R, Part 61 beginning three years from the promulgation of any amendments to dotermine r.;Uat further changes might then be appropriate to move toward the goal of zero vinyl chloride emissions. In the study EPA will consider recent health data and information concerning technological advances in the control of vinyl chloride emissions, /- / /'Jfr-/ ucc 102817
