Ku ya 20 Mata 2023, Ikigo gishinzwe kurengera ibidukikije muri Amerika (EPA) cyatanze itegeko ribuza cyane ikorwa, itunganywa, n'ikwirakwizwa rya methylene chloride mu bucuruzi. EPA ikoresha ububasha bwayo hakurikijwe Ingingo ya 6 (a) y'Itegeko ryo Kugenzura Ibiyobyabwenge (TSCA), ryemerera ikigo gushyiraho ayo mategeko ku binyabutabire. Ingaruka zidafite ishingiro zo gukomereka cyangwa guhura n'ikibazo. Methylene chloride ikoreshwa cyane nk'umusemburo mu bikoresho bifunga, mu bicuruzwa by'imodoka, no mu bikoresho bikuraho irangi n'amabara, kandi inganda nk'iz'imodoka, imiti, n'imiti zishobora kugira ingaruka kuri iri tegeko.
Icyifuzo cya EPA gisaba ko ikoreshwa rya methylene chloride rihagarikwa mu bikorwa byinshi by’inganda n’ubucuruzi. Icyifuzo kirimo gukurwaho, cyane cyane irangi n’amabara akoreshwa mu ndege za gisivili mu gihe cy’imyaka 10 kugira ngo hirindwe kwangirika gukomeye k’umutekano w’igihugu n’ibikorwa remezo by’ingenzi. EPA kandi yongereye iki cyemezo ku ikoreshwa rya dichloromethane mu buryo bwihutirwa rya NASA mu bihe bimwe na bimwe bikomeye cyangwa bikomeye aho nta bundi buryo butekanye mu rwego rwa tekiniki cyangwa mu bukungu.
Icyifuzo cy'ikigo cyakwemera kandi ikoreshwa rya dichloromethane mu gukora hydrofluorocarbon-32 (HFC-32), ikintu gishobora gukoreshwa mu koroshya ihinduka ry'ibindi binyabutabire bivugwa ko bifite ubushobozi bwo kwiyongera k'ubushyuhe bw'isi, gishyigikira ingamba za EPA zo kugabanya ibinyabutabire nk'uko biteganywa n'Itegeko rya Amerika ryo mu 2020 rigenga udushya n'inganda. Ariko, iki kigo kizasaba inganda zikora indege za gisivili, NASA, na HFC-32 gukurikiza gahunda yo kurinda imiti ya methylene chloride aho bakorera irimo imipaka isabwa yo guhura n'ibinyabutabire n'uburyo bikoreshwa mu guhumeka.
Itegeko riteganyijwe nirimara gusohoka mu gitabo cya Leta Zunze Ubumwe za Amerika (Federal Register), EPA izemera ibitekerezo bya rubanda kuri ryo mu gihe cy'iminsi 60 kuri rules.gov/docket/EPA-HQ-OPPT-2020-0465.
Ku wa kabiri, tariki ya 16 Gicurasi 2023, Ikigo gishinzwe kurengera ibidukikije muri Amerika (EPA) cyasohoye umushinga w'itegeko rigena ivugurura ry'ingingo za EPA zishyira mu bikorwa Itegeko ryo Kurwanya Ibiyobyabwenge (TSCA). EPA ikomeza Ikigo gishinzwe ikoranabuhanga rya TSCA Chemical Registry, aho urutonde rw'ibinyabutabire byose bizwi ko biboneka mu bucuruzi muri Leta Zunze Ubumwe za Amerika. Nk’uko TSCA ibivuga, abakora n'abatumiza ibicuruzwa basabwa gutanga amatangazo mbere y'igihe ku binyabutabire bishya keretse habayeho gusonerwa (urugero: ubushakashatsi n'iterambere). EPA igomba kurangiza isuzuma ry'ingaruka ku binyabutabire bishya mbere yo gukora cyangwa gutumiza mu mahanga. Itegeko rigena ubu risobanura ko EPA igomba kurangiza isuzuma ry'ingaruka cyangwa kwemeza imenyesha ry'uko ibinyabutabire bishya 100% bitangwa mbere yuko ibicuruzwa byinjira ku isoko, hakurikijwe impinduka za TSCA zo mu 2016.
Ku ya 21 Mata 2023, Ikigo cya Leta Zunze Ubumwe za Amerika gishinzwe Kurengera Ibidukikije (EPA) cyasohoye umushinga w’Ingamba z’Igihugu zo Kurwanya Ihumana rya Plastic zishobora kugira ingaruka zikomeye ku baturage bagenzurwa barimo inganda zipakira, abacuruzi, abakora iplastike, imicungire y’imyanda ikomeye n’ibikoresho byo kongera gukoresha imyanda, nibindi. Nk’uko umushinga w’ingamba ubivuga, EPA igamije gukuraho irekurwa rya plastike n’indi myanda ikomoka ku butaka mu bidukikije bitarenze 2040, hagamijwe intego zikurikira: kugabanya umwanda mu ikorwa rya plastike, kunoza imicungire y’ibikoresho nyuma yo kubikoresha, gukumira imyanda na micro-/nanoplastics kwinjira mu mazi, no gukuraho imyanda isohoka mu bidukikije. Muri izo ntego, EPA igaragaza inyigo zitandukanye n’ibikorwa byo kugenzura biri kwitabwaho. Mu bikorwa byo kugenzura biri kwitabwaho, EPA yavuze ko irimo kwiga amabwiriza mashya ashingiye ku Itegeko ryo Kugenzura Ibintu Bihumanya ku bigo bigezweho byo kongera gukoresha pyrolysis mu gutunganya ibikoresho fatizo byagaruwe bikavamo plastike yasubiwemo. Iki kigo kandi gisaba kwemeza Amasezerano ya Basel, Leta Zunze Ubumwe za Amerika zemeye ariko ntizemeze mu myaka ya 1990, nk'ubundi buryo bwo guhangana n’ikibazo mpuzamahanga cy’imyanda ya plastike.
Ku ya 16 Ugushyingo 2022, Ikigo gishinzwe kurengera ibidukikije muri Amerika (EPA) cyatanze igitekerezo cyo kongera amafaranga y’imisoro yacyo akoreshwa mu kugenzura ibiyobyabwenge n’igenzura (TSCA), amwe muri yo akaba yikubye kabiri. Iri tangazo ryinyongera ry’amategeko ateganywa rihindura icyifuzo cya EPA, guhera ku ya 11 Mutarama 2021, kugira ngo cyongere amafaranga y’imisoro ya TSCA ahanini kugira ngo ihuzwe n’izamuka ry’ibiciro. TSCA yemerera EPA kwishyuza abakora ibicuruzwa (harimo n’abatumiza ibicuruzwa mu mahanga) ibikorwa by’ikigo hakurikijwe ingingo ya 4, 5, 6 na 14 za TSCA. Nk’uko TSCA ibivuga, EPA isabwa guhindura amafaranga “uko bikenewe” buri myaka itatu. Mu 2018, EPA yasohoye itegeko ryo gukusanya 40 CFR Igice cya 700 Igice cya C rigena amafaranga akoreshwa ubu.
