Kwimithetho ecetywayo eyapapashwa ngoMeyi 3, i-EPA icebise ukuthintela ukusetyenziswa kwe-dichloromethane, ekwaziwa ngokuba yi-dichloromethane, isinyibilikisi esiqhelekileyo kunye noncedo lokucubungula. Isetyenziswa kwiintlobo ngeentlobo zezicelo zabathengi kunye nezentengiso, kubandakanya izincamathelisi kunye nezitywina, iimveliso zeemoto, kunye nezisusi zepeyinti kunye neengubo. Le khemikhali iveliswa ngobuninzi - phakathi kwe-100 yezigidi kunye ne-500 yezigidi zeepawundi phakathi kowama-2016 nowe-2019, ngokutsho kweNgxelo yeDatha yeKhemikhali (CDR) - ngoko ke ukuvalwa, ukuba kupasisiwe, kuya kuba nefuthe elikhulu kumashishini amaninzi. Impembelelo enkulu. isebe.
Isiphakamiso se-EPA sijongana “nomngcipheko ongafanelekanga wokwenzakalisa impilo yabantu ovela kwi-dichloromethane phantsi kweemeko zokusetyenziswa, njengoko kubhaliwe kwiinkcazo zomngcipheko we-EPA phantsi koMthetho woLawulo lweZinto ezinobuthi (TSCA)”. okanye imeko-bume echongiweyo kuvavanyo lomngcipheko we-TSCA kwaye isebenzise iimfuno kangangoko kuyimfuneko ukuze iikhemikhali zingabi yingozi engafanelekanga.
Ukongeza, umthetho ocetywayo we-EPA ufuna iSicwangciso soKhuseleko lweNdawo yoMsebenzi seKhemikhali (i-WCPP), esiquka iimfuno zokuthobela imida yoxinzelelo lokuphefumla kunye nokubeka esweni ukuvezwa kwiimeko ezithile zokusetyenziswa okuqhubekayo kwe-dichloromethane. Iya kubeka kwakhona iimfuno zokugcina iirekhodi kunye nezesaziso ezisezantsi kwiimeko ezahlukeneyo zokusetyenziswa kwaye ibonelele ngezinye iimeko ezinqunyelweyo zokusetyenziswa ezinokubangela ingozi enkulu kukhuseleko lwesizwe kunye neziseko ezibalulekileyo.
Iinkampani ezenza, ezingenisa, ezicubungula, ezisasaza ngorhwebo, ezisebenzisa okanye ezilahla i-methylene chloride okanye iimveliso ezine-methylene chloride zinokuchaphazeleka ngumthetho ocetywayo. Lo mthetho ucetywayo udwelisa iindidi ezingaphezu kwama-40 ezahlukeneyo zamashishini anokuthi alawulwe ngumthetho, kuquka: ukuthengiswa kweekhemikhali ngobuninzi; iiterminals kunye neeterminals zokulayisha ioyile; ukuveliswa kweekhemikhali ezisisiseko ze-organic kunye ne-inorganic; ukulahla inkunkuma enobungozi; amashishini okucubungula izinto; iipeyinti kunye neepeyinti; abavelisi; abakhi bemibhobho kunye nabakhi bomoya; abakhi bepeyinti kunye nabagquma udonga; iivenkile zezixhobo zeemoto kunye nezixhobo; ukuveliswa kwezixhobo zombane kunye neenxalenye; ukuveliswa kwezixhobo zokuwelda kunye nezokufaka i-solder; abathengisi beemoto ezintsha nezisetyenzisiweyo; iinkonzo zokucoca kunye nokuhlamba impahla; kunye noonodoli, amathoyizi kunye nemidlalo.
Umthetho ocetywayo uthi “Phantse ama-35 ekhulwini emveliso ye-methylene chloride yonyaka isetyenziselwa iinjongo zamayeza kwaye ayilawulwa yi-TSCA.” )(B) Nasiphi na isithako ngaphandle kwenkcazo “yekhemikhali” kwisiqendu (ii)-(vi). Ezi zixolelo “zibandakanya … naluphi na ukutya, isongezelelo sokutya, iyeza, izithambiso, okanye isixhobo, njengoko kuchaziwe kwiCandelo 201 loMthetho wezoKutya, iziThambiso, kunye neziThambiso, owenziweyo, ocutshungulwayo, okanye othengiswa njengokutya, isongezelelo sokutya, iyeza, izithambiso okanye isixhobo…”
Kwabo mashishini anokuthi achaphazeleke koku kuthintelwa, kubalulekile ukuqala ukucinga ngezinye iindlela. Uvavanyo lwe-EPA lwezinye iindlela zokusebenzisa i-methylene chloride luchonge ezinye iindlela zokusetyenziswa ezahlukeneyo ezifana nezincamathiselo, izitywini, izicoci, izisusi zepeyinti kunye neengubo, izitywini, kunye nezinto zokuthambisa kunye neegrisi. Nangona kunjalo, kufuneka kuqatshelwe ukuba akukho ndlela zimbi zokongeza kwezobuchwepheshe (kuquka) ezifunyenweyo. Uvavanyo lwezinye iindlela "alucebisi iimveliso ekufuneka zisetyenziswe endaweni ye-dichloromethane; endaweni yoko, injongo yalo kukubonelela ngoluhlu olumele iimveliso ezizezinye kunye neekhemikhali kunye neengozi zazo xa kuthelekiswa ne-dichloromethane, ukuze kubonelelwe ngokuhlolwa kwezinye iindlela ezinokubakho. Iziphumo zithathwa njengenxalenye yomthetho we-TSCA Section 6(a) dichloromethane." Izimvo malunga nomthetho ocetywayo mazifunyanwe kungadlulanga umhla wesi-3 kuJulayi kwaye ziyafumaneka nge-portal ye-electronic rulemaking portal ku-https://www.regulation.gov.
Isikhanyeli: Ngenxa yohlobo oluqhelekileyo lolu hlaziyo, ulwazi olunikiweyo apha lusenokungasebenzi kuzo zonke iimeko, kwaye akufuneki luthathwe amanyathelo ngaphandle kwengcebiso ethile yezomthetho ngokusekelwe kwimeko yakho ethile.
