I te 20 o Paenga-whāwhā, 2023, i whakaarohia e te Tari Tiaki Taiao o Amerika (EPA) tētahi ture e tino aukati ana i te hanga, te tukatuka, me te tohatoha arumoni o te methylene chloride. E whakamahi ana te EPA i tōna mana i raro i te Wāhanga 6(a) o te Ture Whakahaere Matū Paitini (TSCA), e āhei ai te tari ki te whakatakoto i aua aukati ki ngā matū. He mōrearea koretake o te whara, o te āhuatanga rānei. Ko te methylene chloride te mea e whakamahia whānuitia ana hei whakarewa i roto i ngā piripiri me ngā hiri, ngā hua motuka, me ngā tango peita me te paninga, ā, ka pāngia pea ngā ahumahi pēnei i te motuka, te rongoā, me ngā matū e tēnei ture.
Kei roto i te tono a te EPA te aukati i te whakamahinga o te methylene chloride i roto i te nuinga o ngā mahi ahumahi me ngā mahi arumoni. Kei roto i te tono ngā whakawāteatanga, ko te mea nui ko te tango i te peita me ngā paninga e whakamahia ana i roto i te rāngai rererangi ā-iwi mō ngā tau 10 hei karo i ngā kino nui ki te haumarutanga ā-motu me ngā hanganga nui. Kua whakawhānuihia hoki e te EPA tēnei whakawāteatanga ki te whakamahinga ohorere a NASA i te dichloromethane i raro i ētahi āhuatanga nui, kāore hoki he huarahi haumaru ake i te taha hangarau, i te taha ōhanga rānei.
Mā te tono a te tari ka whakaaetia te whakamahinga o te dichloromethane hei whakaputa i te hydrofluorocarbon-32 (HFC-32), he matū ka taea te whakamahi hei whakahaere i te whakawhiti mai i ētahi atu HFC e kīia ana he nui ake te kaha ki te whakamahana ā-ao, hei tautoko i ngā mahi a te EPA ki te whakaiti i ngā HFC. i runga anō i te US Innovation and Manufacturing Act o te tau 2020. Heoi, ka hiahiatia e te tari ngā kaihanga rererangi ā-iwi, te NASA, me te HFC-32 kia whai i tētahi mahere tiaki matū methylene chloride i te wāhi mahi e whakauru ana i ngā here whakaaturanga e hiahiatia ana me te aroturuki whakaaturanga e pā ana.
Kia whakaputaina te ture kua whakaarohia ki te Federal Register, ka whakaaetia e te EPA ngā urupare a te marea mōna mō ngā rā 60 i rules.gov/docket/EPA-HQ-OPPT-2020-0465.
I te Tūrei, te 16 o Mei, 2023, i tukuna e te Tari Tiaki Taiao o Amerika (EPA) tētahi tauira o tētahi ture kua whakaarohia hei whakahou i ngā whakaritenga a te EPA e whakatinana ana i te Ture Whakahaere Matū Paitini (TSCA). Kei te pupuri te EPA i te Rehita Matū TSCA, e whakarārangi ana i ngā matū katoa e mōhiotia ana kei te wātea arumoni i te United States. I raro i te TSCA, me tuku e ngā kaihanga me ngā kawemai ngā pānui-mua mō ngā matū hou ki te kore e pā he whakawāteatanga (hei tauira, te rangahau me te whanaketanga). Me whakaoti e te EPA tētahi aromatawai mōrearea mō tētahi matū hou i mua i te hanga, i te kawemai rānei. Inaianei, e whakamārama ana te ture kua whakaarohia me whakaoti e te EPA tētahi aromatawai mōrearea, me whakaae rānei i tētahi pānui whakawāteatanga mō te 100 ōrau o ngā matū hou i mua i te urunga mai o ngā hua ki te mākete, e ai ki ngā huringa TSCA o te tau 2016.
I te 21 o Paenga-whāwhā, 2023, i tukuna e te Tari Tiaki Taiao o Amerika (EPA) tētahi tauira Rautaki Ārai Parahanga Kirihou ā-Motu ka pā nui ki ngā hapori kua whakahaeretia, tae atu ki te umanga tākai, ngā kaihokohoko, ngā kaihanga kirihou, ngā whakahaere para totoka me ngā whare hangarua, me ētahi atu. E ai ki te tauira rautaki, ko te whāinga a te EPA he whakakore i te tukunga o te kirihou me ētahi atu para whenua ki te taiao i te tau 2040 me ēnei whāinga motuhake: te whakaiti i te parahanga i roto i te hanga kirihou, te whakapai ake i te whakahaere rauemi i muri i te whakamahinga, te ārai i ngā para me ngā micro-/nanoplastics mai i te tomo ki ngā awa, me te tango i ngā para e mawhiti ana mai i te taiao. I roto i ēnei whāinga, ka tautuhia e te EPA ngā rangahau me ngā mahi ture e whakaarohia ana. I roto i ngā mahi ture e whakaarohia ana, i kī te EPA kei te ako i ngā ture hou i raro i te Ture Whakahaere Matū Paitini mō ngā whare hangarua matatau e whakamahi ana i te pyrolysis hei tukatuka i ngā rauemi mata kua whakahokia mai ki roto i ngā kirihou hangarua. Kei te karanga hoki te tari kia whakamanahia te Kawenata Basel, i whakaaetia e te United States engari kāore i whakamanahia i ngā tau 1990, hei huarahi kē atu ki te whakatau i te raruraru o te ao o te para kirihou.
I te 16 o Noema, 2022, i whakaarohia e te Tari Tiaki Taiao o Amerika (EPA) te whakapiki ake i ana utu Ture Whakahaere me ngā Matū Paitini (TSCA) o nāianei, ko ētahi o ēnei ka neke atu i te rua. Mā tēnei Pānui Tāpiri mō te Hanga Ture kua Whakatakotoria e whakarerekē te tono a te EPA, e whai mana ana i te 11 o Hānuere, 2021, kia whakapiki ake i ngā utu a te TSCA hei whakatikatika i te pikinga utu. Ka taea e te TSCA te utu i ngā kaihanga (tae atu ki ngā kawemai) mō ngā mahi a te tari i runga anō i ngā Wāhanga 4, 5, 6 me te 14 o te TSCA. E ai ki te TSCA, me whakatikatika e te EPA ngā utu "inā hiahiatia" i ia toru tau. I te tau 2018, i tukuna e te EPA he ture kohi 40 CFR Wāhanga 700 Wahanga C e whakatakoto ana i te utu o nāianei.
