Pa Epulo 20, 2023, bungwe la US Environmental Protection Agency (EPA) linapereka lamulo loletsa kwambiri kupanga, kukonza, ndi kufalitsa methylene chloride m'mabizinesi. EPA imagwiritsa ntchito mphamvu zake motsatira Gawo 6(a) la Toxic Substances Control Act (TSCA), lomwe limalola bungweli kukhazikitsa ziletso zotere pa mankhwala. Chiwopsezo chosamveka cha kuvulala kapena zochitika. Methylene chloride imagwiritsidwa ntchito kwambiri ngati chosungunulira mu zomatira ndi zomatira, zinthu zamagalimoto, ndi zochotsa utoto ndi zokutira, ndipo mafakitale monga magalimoto, mankhwala, ndi mankhwala amatha kukhudzidwa ndi lamuloli.
Pempho la EPA likufuna kuti pakhale kuletsa kugwiritsa ntchito methylene chloride m'mafakitale ambiri ndi mabizinesi. Pempholi likuphatikizapo kuchotsera, makamaka kuchotsa utoto ndi zophimba zomwe zimagwiritsidwa ntchito m'makampani oyendetsa ndege kwa zaka 10 kuti apewe kuwonongeka kwakukulu kwa chitetezo cha dziko ndi zomangamanga zofunika. EPA yawonjezeranso izi ku NASA pogwiritsa ntchito dichloromethane mwadzidzidzi pansi pa mikhalidwe ina yovuta kapena yovuta yomwe palibe njira zina zotetezeka mwaukadaulo kapena zachuma.
Lingaliro la bungweli lilolanso kugwiritsa ntchito dichloromethane popanga hydrofluorocarbon-32 (HFC-32), chinthu chomwe chingagwiritsidwe ntchito pothandiza kusintha kuchokera ku ma HFC ena omwe amati ali ndi kuthekera kwakukulu kwa kutentha kwa dziko, kuthandizira zoyesayesa za EPA zochepetsa ma HFC, motsatira US Innovation and Manufacturing Act ya 2020. Komabe, bungweli lidzafuna opanga ndege zapagulu, NASA, ndi HFC-32 kuti atsatire dongosolo loteteza mankhwala a methylene chloride kuntchito lomwe limaphatikizapo malire ofunikira pakukhudzana ndi kukhudzana ndi kukhudzana ndi kukhudzana ndi kukhudzana ndi kukhudzana ndi kukhudzana ndi kukhudzana ndi kukhudzana ndi kusuta.
Lamulo lomwe likuperekedwali likangosindikizidwa mu Federal Register, EPA idzalandira ndemanga za anthu onse pa lamuloli kwa masiku 60 pa rules.gov/docket/EPA-HQ-OPPT-2020-0465.
Lachiwiri, pa 16 Meyi, 2023, bungwe la US Environmental Protection Agency (EPA) linatulutsa chikalata cha lamulo lomwe likukonzedwa losintha malamulo a EPA omwe akukhazikitsa Toxic Substances Control Act (TSCA). EPA imasunga TSCA Chemical Registry, yomwe imalemba mankhwala onse omwe amadziwika kuti amapezeka m'masitolo ku United States. Pansi pa TSCA, opanga ndi otumiza kunja akuyenera kupereka zidziwitso za mankhwala atsopano pokhapokha ngati pali kuchotsera (monga kafukufuku ndi chitukuko). EPA iyenera kumaliza kuwunika zoopsa za mankhwala atsopano isanapange kapena kuitanitsa kunja. Lamulo lomwe likukonzedwa tsopano likufotokoza momveka bwino kuti EPA iyenera kumaliza kuwunika zoopsa kapena kuvomereza chidziwitso chochotsera 100 peresenti ya mankhwala atsopano zinthu zisanalowe pamsika, mogwirizana ndi kusintha kwa TSCA kwa 2016.
Pa Epulo 21, 2023, bungwe la US Environmental Protection Agency (EPA) linatulutsa chikalata cha National Plastic Pollution Prevention Strategy chomwe chingakhale ndi zotsatirapo zazikulu pa madera olamulidwa kuphatikizapo makampani opanga ma CD, ogulitsa, opanga mapulasitiki, malo osungira zinyalala zolimba ndi malo obwezeretsanso zinthu, ndi zina zotero. Malinga ndi ndondomekoyi, EPA ikufuna kuthetsa kutulutsidwa kwa zinyalala za pulasitiki ndi zina zochokera kunthaka m'chilengedwe pofika chaka cha 2040 ndi zolinga izi: kuchepetsa kuipitsa chilengedwe popanga pulasitiki, kukonza kasamalidwe ka zinthu mutagwiritsa ntchito, kupewa zinyalala ndi ma micro-/nanoplastics kuti zisalowe m'madzi, ndikuchotsa zinyalala zomwe zimatuluka m'chilengedwe. Pakati pa zolingazi, EPA imazindikira maphunziro osiyanasiyana ndi zochita zowongolera zomwe zikuganiziridwa. Pakati pa zochita zowongolera zomwe zikuganiziridwa, EPA idati ikuphunzira malamulo atsopano pansi pa Toxic Substances Control Act ya malo obwezeretsanso zinthu apamwamba omwe amagwiritsa ntchito pyrolysis kukonza zinthu zopangira zomwe zabwezedwa kukhala mapulasitiki obwezerezedwanso. Bungweli likupemphanso kuti Pangano la Basel livomerezedwe, lomwe United States idavomereza koma silinavomereze m'zaka za m'ma 1990, ngati njira ina yothetsera vuto lapadziko lonse la zinyalala za pulasitiki.
Pa Novembala 16, 2022, bungwe la US Environmental Protection Agency (EPA) linapereka lingaliro lokweza ndalama zomwe limapereka pakali pano za Toxic Substances and Control Act (TSCA), zomwe zina zidzawirikiza kawiri. Chidziwitso chowonjezerachi cha Malamulo Omwe Aperekedwa chikusintha lingaliro la EPA, kuyambira pa Januware 11, 2021, kuti liwonjezere ndalama za TSCA makamaka kuti zigwirizane ndi kukwera kwa mitengo. TSCA imalola EPA kulipiritsa opanga (kuphatikiza otumiza kunja) pazochitika za bungwe motsatira Gawo 4, 5, 6 ndi 14 la TSCA. Malinga ndi TSCA, EPA ikuyenera kusintha ndalama "momwe zimafunikira" zaka zitatu zilizonse. Mu 2018, EPA idapereka lamulo la 40 CFR Part 700 Subpart C lomwe limakhazikitsa ndalama zomwe zilipo.
