Ngomhla wama-20 ku-Epreli, ngo-2023, i-US Environmental Protection Agency (EPA) icebise umthetho othintela kakhulu imveliso, ukucubungula, kunye nokusasazwa kwe-methylene chloride kurhwebo. I-EPA isebenzisa igunya layo phantsi kweCandelo 6(a) loMthetho woLawulo lweZinto ezineTyhefu (TSCA), elivumela i-arhente ukuba ibeke imithetho enjalo kwiikhemikhali. Umngcipheko ongafanelekanga wokwenzakala okanye imeko. I-Methylene chloride isetyenziswa kakhulu njengesinyibilikisi kwizincamathelisi kunye nezitywini, iimveliso zeemoto, kunye nezisusi zepeyinti kunye neengubo, kwaye amashishini afana neemoto, amayeza, kunye neekhemikhali anokuchaphazeleka ngulo mthetho.
Isiphakamiso se-EPA sifuna ukuba kuthintelwe ukusetyenziswa kwe-methylene chloride kwiintlobo ngeentlobo zezicelo zoshishino nezorhwebo. Esi siphakamiso siquka ukukhululwa, ngakumbi ukususwa kwepeyinti kunye neengubo ezisetyenziswa kwicandelo leenqwelo moya zoluntu iminyaka eli-10 ukuze kuthintelwe umonakalo omkhulu kukhuseleko lwesizwe kunye neziseko ezibalulekileyo. I-EPA ikwandise olu khetho ekusebenziseni i-dichloromethane ngequbuliso yi-NASA phantsi kweemeko ezithile ezibalulekileyo okanye ezibalulekileyo apho kungekho ndlela zikhuselekileyo kwezobuchwepheshe okanye kwezoqoqosho.
Isiphakamiso se-arhente siya kuvumela nokusetyenziswa kwe-dichloromethane ukuvelisa i-hydrofluorocarbon-32 (HFC-32), into enokusetyenziswa ukwenza kube lula ukutshintsha ukusuka kwezinye ii-HFC ezithi zinamandla aphezulu okufudumala kwehlabathi, zixhasa imizamo ye-EPA yokunciphisa ii-HFC. ngokuhambelana noMthetho we-US Innovation and Manufacturing Act ka-2020. Nangona kunjalo, i-arhente iya kufuna ukuba abavelisi beenqwelo moya, i-NASA, kunye ne-HFC-32 balandele isicwangciso sokukhusela iikhemikhali ze-methylene chloride kwindawo yokusebenza esiquka imida yokuvezwa efunekayo kunye nokujonga ukuvezwa okunxulumene noko. ngokuphefumla.
Nje ukuba lo mthetho ucetywayo upapashwe kwiRejista yeSizwe, i-EPA iya kwamkela izimvo zikawonke-wonke ngawo kangangeentsuku ezingama-60 apha rules.gov/docket/EPA-HQ-OPPT-2020-0465.
NgoLwesibini, nge-16 kaMeyi, ngo-2023, i-US Environmental Protection Agency (EPA) ikhuphe uyilo lomthetho ocetywayo oguqula amalungiselelo e-EPA asebenzisa uMthetho woLawulo lweZinto ezinobuthi (TSCA). I-EPA igcina i-TSCA Chemical Registry, edwelisa zonke iikhemikhali ezaziwa ngokuba ziyafumaneka kurhwebo e-United States. Phantsi kwe-TSCA, abavelisi kunye nabangenisi kufuneka bangenise izaziso zangaphambi kweekhemikhali ezintsha ngaphandle kokuba kukho ukukhululwa (umz. uphando nophuhliso). I-EPA kufuneka igqibe uvavanyo lomngcipheko wekhemikhali entsha ngaphambi kokuba yenziwe okanye ingeniswe. Umthetho ocetywayo ngoku ucacisa ukuba i-EPA kufuneka igqibe uvavanyo lomngcipheko okanye ivume isaziso sokukhululwa kwi-100 ekhulwini yeekhemikhali ezintsha ngaphambi kokuba iimveliso zingene kwimarike, ngokuhambelana notshintsho lwe-TSCA ka-2016.
Ngomhla wama-21 ku-Epreli, ngo-2023, i-US Environmental Protection Agency (EPA) ikhuphe uyilo lweSizwe lweSicwangciso soThintelo loNgcoliseko lwePlastiki olunokuba nefuthe elikhulu kuluntu olulawulwayo kuquka ishishini lokupakisha, abathengisi, abavelisi beplastiki, ulawulo lwenkunkuma eqinileyo kunye neendawo zokuphinda kusetyenziswe izinto, njl. Ngokwesi sicwangciso soyilo, i-EPA ijonge ukuphelisa ukukhutshwa kweplastiki kunye neminye inkunkuma esemhlabeni kwindalo esingqongileyo ngo-2040 ngeenjongo ezilandelayo: ukunciphisa ungcoliseko kwimveliso yeplastiki, ukuphucula ulawulo lwezinto emva kokusetyenziswa, ukuthintela inkunkuma kunye ne-micro-/nanoplastics ukuba ingene emanzini, kunye nokususa inkunkuma ephumayo kwindalo esingqongileyo. Phakathi kwezi njongo, i-EPA ichonga izifundo ezahlukeneyo kunye nezenzo zomthetho eziqwalaselwayo. Phakathi kwezenzo zomthetho eziqwalaselwayo, i-EPA ithe ifunda imigaqo emitsha phantsi koMthetho woLawulo lweZinto ezinobuthi kwiindawo zokuphinda kusetyenziswe izinto ezisebenzisa i-pyrolysis ukucubungula izinto eziluhlaza ezifunyenweyo zibe ziiplastiki eziphinda zisetyenziswe. Le arhente ikwabiza ukuqinisekiswa kweSivumelwano saseBasel, esavunywa yi-United States kodwa asizange sivume ngeminyaka yoo-1990, njengenye indlela yokujongana nengxaki yehlabathi yenkunkuma yeplastiki.
Ngomhla we-16 kweyeNkanga ngo-2022, i-US Environmental Protection Agency (EPA) iphakamise ukonyuswa kweentlawulo zayo zeToxic Substances and Control Act (TSCA), ezinye zazo eziya kuphindaphindwa kabini. Esi Saziso esongezelelweyo seMithetho eCetywayo siguqula isindululo se-EPA, esisebenza ukususela ngoJanuwari 11, 2021, ukuze konyuswe iintlawulo ze-TSCA ngokukodwa ukuze kulungiswe ukunyuka kwamaxabiso. I-TSCA ivumela i-EPA ukuba ihlawulise abavelisi (kuquka nabangenisi) kwimisebenzi ye-arhente ngokuhambelana neCandelo 4, 5, 6 kunye ne-14 le-TSCA. Ngokwe-TSCA, i-EPA kufuneka ilungise iintlawulo "njengoko kufuneka" rhoqo emva kweminyaka emithathu. Ngo-2018, i-EPA ikhuphe umthetho wokuqokelela we-40 CFR Part 700 Subpart C omisela umrhumo wangoku.
