EPA yakagwisya mulawu uuyeeyelwa kunsi aa Toxic Substances Control Act (TSCA) uukasya kubelesya dichloromethane (alimwi wiitwa kuti dichloromethane naa DCM). Dichloromethane musamu uubelesyegwa munzila zyiingi mumakkampani amumakwebo. Nchintu chibelesyegwa mumakkampani aasiyene. Alimwi ilabelesyegwa kupanga makemikalu aambi, kubikkilizya amafiliji. Makwebo aajatikizyidwe abikkilizya:
Kweendelana anguzu zyakwe zili aansi aaChibeela 6(a) cha TSCA, EPA yakajana kuti dichloromethane ilakonzya kuleta ntenda mpati kubuumi naakuti kubusena. Mukwiingula, EPA yakagwisya mulawu mu May 3, 2023: (1) kukasya kupanga, kubamba, akwaabila methylene chloride kuti ibelesyegwe abasikuula, antoomwe a (2) kukasya kubelesya kwa methylene chloride mumafakitali. mulawu wa EPA wakayeeyelwa ulakonzya kuzumizya FAA, NASA antoomwe a Dipatimenti Yakukwabilila, antoomwe abamwi basikupanga zintu zyakutontozya, kuti bazumanane kubelesya methylene chloride. Kuli eezyi zibelesyo zyakasyaala, mulawu uuyeeyelwa ulakonzya kubikka milawu miyumu mubusena bwakubelekela kuchitila kuti kutabi kujatana ababelesi.
EPA yeezyeezya kuti mulawu ooyu ulajatikizya kwiinda haafu yakubelesya methylene chloride amwaka mu United States. Kuli muzeezo wakulesya kupanga, kubamba, kwaabila akubelesya dichloromethane mukati kamyeezi ilikkumi amusanu. Mbuli mbocakabede kugwisigwa kwa EPA kwamakemikalu amwi aatamani, aakonzya kuyobolola zintu zipona alimwi aakola (PBTs), chiindi chifwiifwi chakugwisigwa kwa methylene chloride tachikonzyi kuzula kuzuzikizya ziyandikana mumakkampani amwi, aboobo inga kwaba twaambo tumwi twakutobela milawu. . Nikuba boobo, mulawu ooyu uuyeeyelwa ulakonzya kuba ampindu mpati kumakani aakupanga akutola zintu mbuli makkampani nalanga-langa kubelesya methylene chloride akuyandaula nzila zimbi zibotu.
EPA iyootambula mizeezo aatala amulawu ooyu kusikila mu July 3, 2023. Makkampani aajatikizyidwe ayelede kuyeeya kupa mizeezo aatala akukonzya kwawo kutobela mulawu, kubikkilizya akunyonganya nzila zyakutola zintu azintu zimwi zityola milawu.
Kuliimya: Akaambo kakuti makani aaya mapya, makani aapegwa aawa taakonzyi kubeleka mubukkale boonse, alimwi taayelede kutobelwa kakunyina lulayo lwamumulawo kweelana abukkale bwanu.
