Ngo-Ephreli 20, 2023, i-US Environmental Protection Agency (EPA) yaphakamisa umthetho ovimbela kakhulu ukukhiqizwa, ukucubungula, kanye nokusatshalaliswa kwe-methylene chloride kwezentengiselwano. I-EPA isebenzisa igunya layo ngaphansi kweSigaba 6(a) soMthetho Wokulawula Izinto Ezinobuthi (TSCA), ovumela i-ejensi ukuthi ibeke imingcele enjalo kumakhemikhali. Ingozi engafanele yokulimala noma isimo. I-Methylene chloride isetshenziswa kakhulu njengesinyibilikisi kuma-adhesive nama-sealant, imikhiqizo yezimoto, kanye ne-removers yopende ne-coating, kanye nezimboni ezifana nezimoto, imithi, kanye namakhemikhali zingathinteka yilo mthetho.
Isiphakamiso se-EPA sifuna ukuvinjelwa kokusetshenziswa kwe-methylene chloride ezinhlotsheni eziningi zezimboni nezentengiselwano. Lesi siphakamiso sihlanganisa ukukhululwa, ikakhulukazi ukususwa kopende kanye nopende iminyaka eyi-10 okusetshenziswa emkhakheni wezindiza zomphakathi ukuze kugwenywe umonakalo omkhulu ekuphepheni kwezwe kanye nengqalasizinda ebalulekile. I-EPA iphinde yandisa lokhu kungafani nokusetshenziswa kwe-dichloromethane okuphuthumayo yi-NASA ngaphansi kwezimo ezithile ezibucayi noma ezibucayi lapho kungekho ezinye izindlela eziphephile ngokobuchwepheshe noma ngokwezomnotho.
Isiphakamiso senhlangano sizovumela nokusetshenziswa kwe-dichloromethane ukukhiqiza i-hydrofluorocarbon-32 (HFC-32), into engasetshenziswa ukwenza kube lula ukushintsha kusuka kwamanye ama-HFC athi anamandla okushisa komhlaba aphezulu, okusekela imizamo ye-EPA yokunciphisa ama-HFC ngokuhambisana noMthetho Wokusungula Nokukhiqiza wase-US ka-2020. Kodwa-ke, le nhlangano izodinga abakhiqizi bezindiza zomphakathi, i-NASA, kanye ne-HFC-32 ukuthi balandele uhlelo lokuvikela amakhemikhali endaweni yokusebenza lwe-methylene chloride oluhlanganisa imikhawulo yokuchayeka edingekayo kanye nokuqapha ukuchayeka okuhambisanayo. ngokuphefumula.
Uma umthetho ohlongozwayo usushicilelwe ku-Federal Register, i-EPA izokwamukela imibono yomphakathi ngawo izinsuku ezingama-60 ku-rules.gov/docket/EPA-HQ-OPPT-2020-0465.
NgoLwesibili, mhla ziyi-16 kuNhlaba 2023, i-US Environmental Protection Agency (EPA) ikhiphe uhlaka lomthetho ohlongozwayo oguqula izimiso ze-EPA ezisebenzisa uMthetho Wokulawula Izinto Ezinobuthi (TSCA). I-EPA igcina i-TSCA Chemical Registry, ebala wonke amakhemikhali aziwa ukuthi atholakala kwezentengiselwano e-United States. Ngaphansi kwe-TSCA, abakhiqizi nabangenisi kudingeka bathumele izaziso zangaphambi kwamakhemikhali amasha ngaphandle kokuthi kusebenza ukukhululwa (isib. ucwaningo nentuthuko). I-EPA kumele iqedele ukuhlolwa kobungozi bekhemikhali entsha ngaphambi kokukhiqiza noma ukungenisa. Umthetho ohlongozwayo manje ucacisa ukuthi i-EPA kumele iqedele ukuhlolwa kobungozi noma ivume isaziso sokukhululwa ngamaphesenti ayi-100 amakhemikhali amasha ngaphambi kokuba imikhiqizo ingene emakethe, ngokuhambisana nezinguquko ze-TSCA zango-2016.
Ngo-Ephreli 21, 2023, i-US Environmental Protection Agency (EPA) yakhipha uhlaka lweNational Plastic Pollution Prevention Strategy olungaba nomthelela omkhulu emiphakathini elawulwayo okuhlanganisa imboni yokupakisha, abathengisi, abakhiqizi bepulasitiki, izindawo zokuphathwa kwemfucuza eqinile kanye nokuvuselela kabusha, njll. Ngokusho kohlaka lwesu, i-EPA ihlose ukuqeda ukukhishwa kwemfucuza yepulasitiki kanye neminye esemhlabeni emvelweni ngo-2040 ngezinhloso ezilandelayo: ukunciphisa ukungcola ekukhiqizweni kwepulasitiki, ukuthuthukisa ukuphathwa kwezinto ngemuva kokusetshenziswa, ukuvimbela imfucuza kanye nama-micro-/nanoplastics ukuthi angangeni emifuleni yamanzi, kanye nokususa imfucuza ephumayo emvelweni. Phakathi kwalezi zinhloso, i-EPA ikhomba izifundo ezahlukahlukene kanye nezenzo zomthetho ezicatshangelwayo. Phakathi kwezenzo zomthetho ezicatshangelwayo, i-EPA ithe ifunda imithetho emisha ngaphansi koMthetho Wokulawula Izinto Ezinobuthi zezindawo zokuvuselela kabusha ezithuthukisiwe ezisebenzisa i-pyrolysis ukucubungula izinto zokusetshenziswa ezitholiwe zibe amapulasitiki asetshenziswe kabusha. Le nhlangano iphinde icele ukuqinisekiswa kweSivumelwano saseBasel, i-United States eyavumelana naso kodwa ayizange isiqinisekise ngawo-1990, njengenye indlela yokubhekana nenkinga yomhlaba wonke yemfucuza yepulasitiki.
Ngomhlaka-16 Novemba 2022, i-US Environmental Protection Agency (EPA) iphakamise ukwenyusa izimali zayo zamanje ze-Toxic Substances and Control Act (TSCA), ezinye zazo ezizophindeka kabili. Lesi Saziso esengeziwe Sokwenza Imithetho Okuhlongozwayo siguqula isiphakamiso se-EPA, esiqala ukusebenza ngomhlaka-11 Januwari 2021, ukuze kwandiswe izimali ze-TSCA ngokuyinhloko ukuze kulungiswe ukukhuphuka kwamanani entengo. I-TSCA ivumela i-EPA ukuthi ikhokhise abakhiqizi (kufaka phakathi abangenisi) ngemisebenzi ye-ejensi ngokuhambisana neZigaba 4, 5, 6 kanye no-14 ze-TSCA. Ngokusho kwe-TSCA, i-EPA kudingeka ukuthi ilungise izimali "njengoba kudingeka" njalo eminyakeni emithathu. Ngo-2018, i-EPA yakhipha umthetho wokuqoqwa kwe-40 CFR Part 700 Subpart C obeka imali yamanje.
