Mu mategeko yatanzwe yasohotse ku ya 3 Gicurasi, EPA yatanze igitekerezo cyo guhagarika ikoreshwa rya dichloromethane, izwi kandi nka dichloromethane, umuti usanzwe wo gushonga no gutunganya. Ikoreshwa mu buryo butandukanye n’ubw’abaguzi n’abacuruzi, harimo kole n’ibifunga, ibicuruzwa by’imodoka, n’ibikuraho amarangi n’amabara. Iyi miti ikorwa ku bwinshi - hagati ya miliyoni 100 na miliyoni 500 z’amapawundi hagati ya 2016 na 2019, nk’uko Raporo y’amakuru y’ibinyabutabire (CDR) ibivuga - bityo itegeko ribuza, riramutse ryemejwe, ryagira ingaruka zikomeye ku nganda nyinshi. Ingaruka zikomeye. Ishami.
Igitekerezo cya EPA kivuga ku “byago bidafite ishingiro byo kwangiza ubuzima bw’abantu biturutse kuri dichloromethane mu gihe cyo kuyikoresha, nk’uko byanditswe mu bisobanuro bya EPA ku byago nk’uko biteganywa n’Itegeko ryo Kugenzura Ibiyobyabwenge (TSCA)” cyangwa ibidukikije byagaragajwe mu isuzuma ry’ibyago bya TSCA kandi bigashyira mu bikorwa ibisabwa ku buryo ibinyabutabire bitazongera guteza ibyago bidafite ishingiro.
Byongeye kandi, itegeko ryatanzwe na EPA risaba Gahunda yo Kurinda Ibiyobyabwenge mu Kazi (WCPP), irimo ibisabwa kugira ngo hubahirizwa imipaka y’ibipimo byo guhumeka no kugenzura uburyo bwo guhumeka ku bintu bimwe na bimwe byo gukoresha dichloromethane buri gihe. Rizashyiraho kandi ibisabwa mu kubika inyandiko no kumenyesha ibintu bikurikira ku bintu bitandukanye byo gukoresha, kandi ritange igihe runaka kidasabwa ku bijyanye n’ibisabwa mu gukoresha ibintu bishobora kwangiza umutekano w’igihugu n’ibikorwa remezo by’ingenzi.
Amasosiyete akora, atumiza mu mahanga, atunganya, akwirakwiza mu bucuruzi, akoresha cyangwa ajugunya methylene chloride cyangwa ibicuruzwa birimo methylene chloride ashobora kugira ingaruka ku itegeko ryatanzwe. Iri tegeko rikubiyemo ibyiciro birenga 40 bitandukanye by'inganda zishobora kugengwa n'iri tegeko, birimo: kugurisha imiti; aho gupakira amavuta n'aho gupakira; gukora imiti y'ibanze ikomoka ku bimera n'ibitari umwimerere; kujugunya imyanda ihumanya; ibigo bikora ibikoresho; amarangi n'irangi. abakora; abakora imirimo y'amazi n'ibikoresho bikonjesha; abakora imirimo yo gusiga amarangi no gupfuka inkuta; amaduka acuruza ibice by'imodoka n'ibindi bikoresho; gukora ibikoresho by'amashanyarazi n'ibice byabyo; gukora ibikoresho byo gusudira no gusodesha; abacuruzi b'imodoka nshya n'izakoreshejwe; serivisi zo gusukura no kumesa imyenda; ndetse n'ibipupe, ibikinisho n'imikino.
Itegeko ryatanzwe rivuga ko “Hafi 35% by'umusaruro wa methylene chloride buri mwaka ukoreshwa mu rwego rw'imiti kandi ntugengwa cyangwa ngo ugenzurwe na TSCA.” (B) ) Ikintu icyo ari cyo cyose kitari igisobanuro cya “chemical” mu gika cya (ii)-(vi). Ibi birengagizwa “bikubiyemo… ibiryo byose, inyongeramusaruro, imiti, ubwiza, cyangwa igikoresho, nk'uko bisobanurwa mu ngingo ya 201 y'Itegeko rya Leta rigenga ibiribwa, imiti, n'ubwiza, bikorerwa, bigatunganywa, cyangwa bicuruzwa nk'ibiryo, inyongeramusaruro y'ibiribwa, imiti, ubwiza cyangwa igikoresho…”
Ku nganda zishobora kugira ingaruka kuri iri hagarikwa, ni ngombwa gutangira gutekereza ku zindi nzira. Isuzuma rya EPA ku zindi nzira zitari ikoreshwa rya methylene chloride ryagaragaje izindi nzira zo gukoresha mu buryo butandukanye nka kole, sealants, degreasers, irangi n'imyenda, sealants, n'amavuta n'amavuta. Ariko, ni ngombwa kumenya ko nta zindi nzira zabonetse mu buryo bukoresha ikoranabuhanga (harimo) zakoreshejwe. Isuzuma ry'izindi nzira "ntirisaba ibicuruzwa bigomba gukoreshwa mu mwanya wa dichloromethane; ahubwo, intego yaryo ni ugutanga urutonde rw'ibindi bicuruzwa n'imiti n'ibyago byabyo ugereranije na dichloromethane, kugira ngo hatangwe urutonde rw'ibindi bicuruzwa bishobora guhindurwa. Ibisubizo bifatwa nk'igice cy'itegeko rya dichloromethane rya TSCA Ingingo ya 6 (a). Ibitekerezo ku itegeko riteganyijwe bigomba kwakirwa bitarenze ku ya 3 Nyakanga kandi biboneka binyuze ku rubuga rwa leta rushinzwe amategeko kuri https://www.regulation.gov.
Icyitonderwa: Bitewe n'imiterere rusange y'iri vugurura, amakuru atangwa hano ashobora kudakurikizwa mu bihe byose, kandi ntagomba gukurikizwa hatabayeho inama z'amategeko zihariye hashingiwe ku mimerere yawe.
