Mu mabwiriza yatanzwe yasohotse ku ya 3 Gicurasi, Ikigo gishinzwe kurengera ibidukikije muri Amerika giteganya 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 irangi n’amabara. Iyi miti ikorwa mu bwinshi - hagati ya miliyoni 100 na miliyoni 500 z’amapawundi kuva mu 2016 kugeza 2019, nk’uko raporo y’amakuru y’ibinyabutabire (CDR) ibivuga - bityo iryo tegeko, niriremezwa, ryagira ingaruka zikomeye ku nganda nyinshi.
Igitekerezo cya EPA kivuga ku “byago bidafite ishingiro ku buzima bw’abantu dichloromethane itera mu gihe cyo kuyikoresha, nk’uko byanditswe mu bisobanuro bya EPA ku byago nk’uko biteganywa n’Itegeko ryo Kugenzura Ibiyobyabwenge (TSCA) ribivuga”. Isuzuma ry’ibyago bya TSCA n’ishyirwa mu bikorwa ry’ibisabwa ku rugero rukenewe kugira ngo iki kinyabutabire kitazongera gutera ibyago bidafite ishingiro.
Byongeye kandi, itegeko ryatanzwe na EPA risaba Gahunda yo Kurinda Ahantu Hakorerwa Ibiyobyabwenge (WCPP), irimo ibisabwa kugira ngo habeho imipaka yo guhumeka no kugenzura ikoreshwa rya methylene chloride mu buryo buhoraho. Rizashyiraho kandi ibisabwa mu kubika inyandiko no gutanga amakuru ku buryo butandukanye bwo gukoresha, kandi ritange igihe runaka kidasabwa ku bijyanye n'ikoreshwa ry'ibiyobyabwenge 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 gukurikizwa n'iri tegeko, birimo: kugurisha imiti, aho gupakira peteroli n'aho gupakira, gukora imiti y'ibanze ikomoka ku bimera n'ibitari umwimerere, gusohora imyanda ihumanya, kongera gukoresha ibikoresho, gusiga amarangi n'irangi; abakora imirimo yo gusana no gukonjesha; abakora imirimo yo gusiga amarangi no gushushanya inkuta; amaduka acuruza ibikoresho by'imodoka n'ibindi bikoresho; gukora ibikoresho by'amashanyarazi n'ibice byabyo; gukora ibikoresho byo gusora; abacuruza imodoka nshya n'izakoreshejwe; serivisi zo gusukura no kumesa imyenda; gukora ibipupe, ibikinisho n'imikino.
Itegeko ryatanzwe rivuga ko “Hafi 35% by'umusaruro wa methylene chloride ukorwa buri mwaka ukoreshwa mu miti idakurikije TSCA kandi idakurikije iri tegeko.” ridashyirwa mu bisobanuro bya “chemical” mu gika cya (B) (ii) kugeza kuri (vi). Ibi birego “bikubiyemo… ibiryo byose, inyongeramusaruro, imiti, ubwiza, cyangwa igikoresho, nk'uko bisobanurwa mu ngingo ya 201 y'Itegeko rya Leta rigenga ibiribwa, imiti, n'ubwiza, iyo bikozwe, bigatunganywa, cyangwa bigakwirakwizwa mu bucuruzi kugira ngo bikoreshwe nk'imiti. , ubwiza cyangwa ibikoresho…”
Ku nganda zizagerwaho n’iri hagarikwa, ni ngombwa gutangira gushaka ubundi buryo. Isuzuma rya EPA ku buryo bwo guhindura methylene chloride ryagaragaje ubundi buryo bwo gukoresha mu buryo butandukanye nka kole, ibifunga, ibikuraho amavuta, ibikuraho amarangi n’ibisigazwa, ibifunga, n’amavuta n’amavuta. Ariko, ni ngombwa kumenya ko nta bindi bisimbura inyongeramusaruro z’ikoranabuhanga (n’ibindi) byabonetse. Isuzuma ry’ubundi buryo “ntirisaba ko ibicuruzwa bikoreshwa mu mwanya wa dichloromethane; ahubwo, intego yaryo ni ugutanga urutonde rw’ibicuruzwa bisimbura ibindi n’ibibigize imiti ndetse n’ingaruka zabyo zijyanye na dichloromethane, kugira ngo harebwe ko ibisubizo byo gupima ubundi buryo bishobora gufatwa nk’igice cy’amategeko ya TSCA Ingingo ya 6 (a) ya methylene chloride.” Ibitekerezo ku itegeko ryatanzwe bigomba kwakirwa bitarenze ku ya 3 Nyakanga kandi biboneka ku rubuga rwa leta rushinzwe amategeko kuri https://www.regulations.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.
