Emithethweni ehlongozwayo eyanyatheliswa ngoMeyi 3, i-EPA iphakamise ukuvimbela ukusetshenziswa okuningi kwe-dichloromethane, eyaziwa nangokuthi i-dichloromethane, isithako esivamile sokuxazulula nokucubungula. Isetshenziswa ezinhlotsheni ezahlukene zezicelo zabathengi nezentengiselwano, kufaka phakathi izinamathiselo nama-sealant, imikhiqizo yezimoto, kanye nezinsimbi zokususa upende nokumboza. Leli khemikhali likhiqizwa ngobuningi obukhulu - phakathi kwamaphawundi ayizigidi eziyi-100 kanye nama-500 phakathi kuka-2016 no-2019, ngokusho kwe-Chemical Data Report (CDR) - ngakho-ke ukuvinjelwa, uma kuphasiswa, kungaba nemiphumela emikhulu ezimbonini eziningi. Umthelela omkhulu. umnyango.
Isiphakamiso se-EPA sikhuluma “ngengozi engafanele yokulimala empilweni yabantu evela ku-dichloromethane ngaphansi kwezimo zokusetshenziswa, njengoba kubhalwe ezincazelweni zengozi ye-EPA ngaphansi koMthetho Wokulawula Izinto Ezinobuthi (TSCA)”. noma indawo ehlonzwe ekuhlolweni kwengozi ye-TSCA futhi sisebenzise izidingo ngezinga elidingekayo ukuze amakhemikhali angabe esabeka ingozi engafanele.
Ngaphezu kwalokho, umthetho ohlongozwayo we-EPA udinga Uhlelo Lokuvikela Indawo Yokusebenza Yamakhemikhali (i-WCPP), oluhlanganisa izidingo zokuthobela imikhawulo yokuhlushwa kokuphefumula kanye nokuqapha ukuchayeka ezimweni ezithile zokusetshenziswa okuqhubekayo kwe-dichloromethane. Luzophinde lubeke izidingo zokugcina amarekhodi kanye nezesaziso ezingezansi ezimweni eziningana zokusetshenziswa futhi lunikeze izimo ezithile ezinqunyelwe isikhathi ezidingweni zokusetshenziswa ezingadala umonakalo omkhulu ekuphepheni kwezwe kanye nengqalasizinda ebalulekile.
Izinkampani ezikhiqiza, ezingenisa, ezicubungula, ezisabalalisa ngokuhweba, ezisebenzisa noma ezilahla i-methylene chloride noma imikhiqizo equkethe i-methylene chloride zingase zithinteke ngumthetho ohlongozwayo. Umthetho ohlongozwayo ubala imikhakha engaphezu kuka-40 ehlukene yezimboni ezingase zibe ngaphansi komthetho, okuhlanganisa: ukuthengiswa kwamakhemikhali ngobuningi; izindawo zokugcina uwoyela kanye nezindawo zokugcina; ukukhiqizwa kwamakhemikhali ayisisekelo emvelo kanye nezindawo ezingaphili; ukulahlwa kwemfucuza eyingozi; amabhizinisi okucubungula izinto; upende nopende; abakhiqizi; osonkontileka bamapayipi kanye neziphephetha-moya; osonkontileka bokupenda kanye nokubopha udonga; izitolo zezingxenye zezimoto nezesekeli; ukukhiqizwa kwemishini kagesi kanye nezingxenye; ukukhiqizwa kwemishini yokushisela kanye neyokushisela; abathengisi bezimoto ezintsha nezisetshenzisiwe; izinsizakalo zokuhlanza kanye nezokuwasha izingubo; kanye nonodoli, amathoyizi nemidlalo. ukukhiqizwa.
Umthetho ohlongozwayo uthi “Cishe amaphesenti angu-35 okukhiqizwa kwe-methylene chloride minyaka yonke asetshenziselwa izinjongo zokwelapha futhi awalawulwa yi-TSCA.”)(B) Noma yimuphi umuthi ngaphandle kwencazelo “yamakhemikhali” ezigabeni (ii)-(vi). Lokhu kukhululwa “kufaka phakathi … noma yikuphi ukudla, isengezo sokudla, umuthi, izimonyo, noma idivayisi, njengoba kuchazwe eSigabeni 201 soMthetho Wokudla, Izidakamizwa, kanye Nezimonyo Kahulumeni, okhiqizwa, ocutshungulwa, noma othengiswa njengokudla, isengezo sokudla, umuthi, izimonyo noma idivayisi…”
Kulabo mboni abangase bathintwe yilokhu kuvinjelwa, kubalulekile ukuqala ukucabanga ngezinye izindlela. Ukuhlolwa kwe-EPA kwezinye izindlela zokusebenzisa i-methylene chloride kuveze ezinye izindlela zokusetshenziswa okuhlukahlukene njengezinamathiselo, izivalo, izihlanzi, izisusa upende nokumboza, izivalo, kanye nezinto zokugcoba namafutha. Kodwa-ke, kufanele kuqashelwe ukuthi azikho ezinye izindlela ezingasetshenziswa esikhundleni sezithasiselo zobuchwepheshe (kufaka phakathi) ezitholakele. Ukuhlolwa kwezinye izindlela "akuncomi imikhiqizo okufanele isetshenziswe esikhundleni se-dichloromethane; kunalokho, inhloso yayo ukuhlinzeka ngohlu olumele imikhiqizo ehlukile namakhemikhali kanye nezingozi zawo uma kuqhathaniswa ne-dichloromethane, ukuze kuhlinzekwe ukuhlolwa kwezinye izindlela ezingaba khona. Imiphumela ibhekwa njengengxenye yomthetho we-TSCA Section 6(a) dichloromethane." Imibono ngomthetho ohlongozwayo kumele itholakale kungakapheli umhlaka-3 Julayi futhi iyatholakala nge-portal kahulumeni yokwenza imithetho ye-elekthronikhi ku-https://www.regulation.gov.
Isixwayiso: Ngenxa yohlobo olujwayelekile lwalesi sibuyekezo, ulwazi olunikezwe lapha lungase lungasebenzi kuzo zonke izimo, futhi akufanele lusetshenziswe ngaphandle kweseluleko esithile sezomthetho ngokusekelwe esimweni sakho esithile.
