I te 3 o Mei, 2023, i whakaputa te EPA i tētahi ture kua whakaarohia ki roto i te Federal Register hei aukati i te nuinga o ngā whakamahinga o te methylene chloride.
, ā, ko te dichloromethane te matū tuarua e whakahaeretia ana tōna mōrearea i raro i te tukanga whakahou i hangaia e Frank R. Lautenberg. Te Ture Haumaru Matū o te rautau 21 o te tau 2016. I te tau kua hipa, i whakaarohia e te tari ētahi tikanga hei tiaki i te tangata mai i te pānga o te asbestos.
He maha ngā huarahi e whakamahia ai te dichloromethane, tae atu ki ngā tono kaihoko pēnei i ngā tango hinu aerosol me ngā horoi paraihe mō ngā peita me ngā paninga, ngā tono arumoni pēnei i ngā piripiri me ngā hiri, me ngā tono ahumahi mō te hanga i ētahi atu matū. Hei tauira, ka whakamahia te dichloromethane hei takawaenga matū i roto i te hanga o ngā hydrofluorocarbons (HFCs) 32, e whakamahia ana i roto i ngā pouaka whakamatao whakaranu i hangaia hei whakakapi i ngā matū he nui ake te kaha ki te whakamahana ā-ao.
E ai ki te Tari Tiaki Taiao, neke atu i te 85 ngā tūroro kua mate i te pānga ohorere ki te methylene chloride mai i te tau 1980, ko te nuinga o rātou he kaimahi kirimana whakapaipai whare, ahakoa i tino whakangungua rātou, ā, i rite hoki ki ngā taputapu tiaki whaiaro.
Kāore i te tika te whakamāramatanga a te tari mō te mōrearea mō te dichloromethane, ā, e hangai ana ki ngā mōrearea e pā ana ki ngā kaimahi, ki ngā tohunga ngaio kāore e whakamahi ana i te matū (ngā kaimahi e tata ana engari kāore e pā tika ana ki te matū), ki ngā kaihoko me te hunga e tata ana ki ngā kaihoko. Kua tautuhia e te Tari Tiaki Taiao te mōrearea o ngā pānga kino ki te hauora tangata mai i te manawa me te pānga ki te kiri o te methylene chloride, tae atu ki te paitini roro, ngā pānga ki te ate, me te mate pukupuku.
Mā ngā ture whakahaere mōrearea kua whakaarohia ka tere te whakaiti i te hanga, te tukatuka me te tohatoha o te methylene chloride mō ngā whakamahinga katoa a ngā kaihoko me te nuinga o ngā whakamahinga ahumahi me ngā whakamahinga arumoni, ā, ko te nuinga o ēnei ka tino tutuki i roto i ngā marama 15. I whakaatuhia e te tātaritanga mō te nuinga o ngā whakamahinga methylene chloride kua whakaarohia e te EPA kia aukatia, he rite tonu te utu me te whai huatanga o ngā hua methylene chloride.
"He mārama ngā taunakitanga pūtaiao mō te methylene chloride, ā, ka taea e te pānga ki te methylene chloride te whakararu i te hauora o te tini tāngata, tae atu ki te mate," te kī a te tumuaki o te EPA, a Michael S. Regan, i roto i tētahi panui pāpāho mai i te tari. "Koia te take e mahi ana te EPA ki te taunaki i te aukati i te nuinga o ngā whakamahinga o tēnei matū, me te tiaki i te hauora o ngā kaimahi me te whakaiti i te pānga i roto i ngā āhuatanga katoa mā te whakauru i ngā mana whakahaere kaha ake i te wāhi mahi. E whakaatu ana tēnei aukati hītori i te ahunga whakamua nui kua mahia e mātou ki te whakatinana i ngā ārai haumaru matū hou me te tango i ngā mahi kua roa e tatarihia ana hei tiaki pai ake i te hauora o te marea."
"Mō te hanga ahumahi, te tukatuka ahumahi, me te whakamahinga ā-motu kāore te EPA e tūtohu ana kia aukatia, ka tukuna e te EPA he kaupapa tiaki matū i te wāhi mahi e whakauru ana i ngā herenga pānga kaha hei tiaki pai ake i ngā kaimahi," te kī a te EPA i roto i tētahi kōrero. tērā pea kua tutuki kē ngā herenga pānga kaha kua whakaritea mō te methylene chloride. Mā ēnei whakaritenga kua whakaritea ka taea tonu te tukatuka i te methylene chloride hei whakaputa i ngā matū he mea nui ki te whawhai ki te mahana o te ao. He mea nui te mahi a ngā pouaka whakamatao e pai ana ki te āhuarangi me ētahi atu matū ki te whawhai ki te huringa āhuarangi. , ā, ka tautoko te ture kua whakaritea e te EPA i ngā mahi whakaiti tukunga atu."
Hei tāpiritanga, e taunaki ana te EPA kia mau tonu te whakahaere i ētahi whakamahinga o te dichloromethane e hiahiatia ana e NASA, DOD me te FAA i roto i te wāhi mahi, nā te mea ka taea te whakaiti i te pānga ki ēnei āhuatanga tino uaua, ā, ka whakaitihia te mōrearea ki ngā kaimahi.
"Ka tiakina hoki te hapori mai i te pānga ki te methylene chloride e ngā aukati me ngā here kua whakaritea," te kī a te kōrero. "Ma te whakamahi i ngā raraunga pānga ki ngā tukunga paitini e ono tau, kua tautuhia e te EPA he iti noa ngā whare hei tūponotanga mō ngā hapori kua taiepatia. Ka kapi te aukati i roto i te ture kua whakaritea e te EPA i te whakamahinga tonu o te methylene chloride i te nuinga o aua whare, ā, ka whakakorea te tūponotanga ki te tūponotanga mō ngā hapori tata."
Ka whakaaetia ngā kōrero mō te ture kua whakaarohia mā te Federal Electronic Rulemaking Portal, nama kōnae EPA-HQ-OPPT-2020-0465, te rā kati ko te 3 o Hūrae, 2023.
