Mu 20 Mukubwekaangala, 2023, mbunga ya US Environmental Protection Agency (EPA) yakabikka mulawu uukasya kupanga, kubamba, akusambala methylene chloride. EPA ibelesya nguzu zyakwe aansi aaChibeela 6(a) chamulawu wakukwabilila misamu iikola (TSCA), ooyo uuzumizya mbunga eeyi kuti ilesye misamu eeyi. Ntenda iitali kabotu yakulichisa naakuti bukkale. Methylene chloride ibelesyegwa kapati mbuli chintu chiyumu muzintu zinamatika, zintu zipangwa mumyootokala, azintu zigwisya penti azintu zivwumbidwe, alimwi makkampani aali mbuli myootokala, misamu, amakemikalu alakonzya kujatikizyigwa amulawu ooyu.
Muzeezo wa EPA uyanda kuti kube kukasya kubelesya methylene chloride mumilimo myiingi yamakkampani amumakwebo. Muzeezo ooyu ulabikkilizya akugwisigwa, ikapati kwamyaka ilikkumi yakugwisya penti azintu zibelesyegwa mumulimo wa ndeke zyabantu boonse kutegwa kutabi kunyonyooka kupati kwalukwabililo lwacisi alimwi azintu ziyandika kapati. EPA alimwi yakayungizya kusiyana ooku ku NASA kubelesya dichloromethane muchiindi chakufwambaana mubukkale bumwi bukatazya naakuti butakwe nzila zimbi zikwabilidwe.
Muzeezo wa mbunga ulakonzya kuzumizya kubelesya dichloromethane kupanga hydrofluorocarbon-32 (HFC-32), chintu chikonzya kubelesegwa kugwasya kuzwa kuma HFC aambi aambwa kuti alakonzya kupa kuti nyika ipye, ikugwasyilizya kusoleka kwa EPA mukucesya ma HFC. kweendelana amulawu wa US Innovation and Manufacturing Act of 2020. Nokuba boobo, mbunga iyooambila basikupanga ndeke, NASA, antoomwe a HFC-32 kuti batobele nzila yakukwabilila misamu ya methylene chloride kubusena bwakubelekela iibikkilizya milawu yeelede kubelesyegwa akulangisisya ntenda. akuyoya.
Mulawu uuyeeyelwa wamwaigwa mu Federal Register, EPA iyootambula mizeezo yabantu boonse kwamazuba aali 60 a rules.gov/docket/EPA-HQ-OPPT-2020-0465.
muliBwabili, Mukubwe Kaangala 16, 2023, mbunga ya US Environmental Protection Agency (EPA) yakagwisya mulawu uuyanda kuchincha zyeelelo zya EPA zibelesya mulawu wakukwabilila misamu iikola (TSCA). EPA ilabamba bbuku lya TSCA Chemical Registry, eelyo lilembedwe misamu yoonse iizyibidwe kuti ilajanwa mumakwebo mu United States. Munsi lya TSCA, basikupanga abasikuula zintu kuzwa kunze beelede kutumina zizibisyo zyamakemikalu mapya kunze kwakuti kwaba kulekelelwa (nkokuti buvwuntauzi akusumpula). EPA yeelede kumanizya kulanga-langa ntenda zyamakemikalu mapya katanapanga naakuti kuleta kuzwa kunze. mulawu uuyeeyelwa lino ulasalazya kuti EPA yeelede kumanizya kulanga-langa ntenda naakuti kuzumizya lugwalo lwakuleka kubelesya misamu mipya iili 100 mu 100 kaitananjila mumusika, kweendelana akusanduka kwa 2016 TSCA.
Mu 21 Mukubwekaangala, 2023, mbunga ya US Environmental Protection Agency (EPA) yakagwisya nzila yakulesya kusofwaala kwamapulasitiki yanyika yoonse eeyo iikonzya kuba ampindu mpati kubantu bali mumilawu kubikkilizya abasikupanga zintu, basambazi, basikupanga mapulasitiki, kweendelezya tombe liyumu alimwi amasena aakubelesya zintu zipya, azimwi. Kweelana amulongo ooyu, EPA yakagwisya nzila yakugwisya tombe lyamapulasitiki alimwi azimwi zintu zizwa munyika mubusena kusikila mu 2040 amakanze aaya: kuchesya busofwaazi mukupanga mapulasitiki, kusumpula kweendelezya zintu zyamana kubelesegwa, kulesya tombe ama micro-/nanoplastics kuti zitanjili mumaanzi, akugwisya tombe lizwa mubusena. Akati kamakanze aaya, EPA ilasala ziiyo zisiyene-siyene anzila zyakweendelezya zili mukulangwa-langwa. Akati kazyintu zyeelede kuchitwa, EPA yakaamba kuti ili mukwiiya milawu mipya aansi aamulawu wa Toxic Substances Control Act kumasena aabelesya zintu zyakalengwa buya zibelesya nzila ya pyrolysis kuchita kuti zintu zibelesyegwe kale kuti zibe mapulasitiki aabelesyegwa kale. Eeyi mbunga alimwi ilalomba kuti chizuminano chaBasel chizuminwe, eecho chizuminano cha Amelika nchochakazumina pesi nchochatakazumizya muma 1990, mbuli nzila aimbi yakumana penzi lyanyika yoonse lyakusowa tombe lyamapulasitiki.
Mu 16, 2022, mbunga ya US Environmental Protection Agency (EPA) yakakankaizya kuti iyungizye mali yayo ya Toxic Substances and Control Act (TSCA), imwi yayo iyooyungizyigwa ziindi zyobile. Eechi chizibisyo chakuyungizya chakupanga milawu chichincha muzeezo wa EPA, uutalika mu January 11, 2021, kuti uyungizye mali ya TSCA ikapati akaambo kakutanta kwamiulo. TSCA ilazumizya EPA kuti ibbadale basikupanga (kubikkilizya abasikuleta kuzwa kunze) kumilimu yambunga kweendelana azibeela 4, 5, 6 a 14 zya TSCA. Kweelana a TSCA, EPA yeelede kuchincha mali "mbuli mbokuyandika" amyaka yotatwe yoonse. Mu 2018, EPA yakagwisya mulawu wakuyobolola mali wa 40 CFR Part 700 Subpart C ooyo uubikka muulo uuliko lino.
