Ma nā lula i manaʻo ʻia i paʻi ʻia ma Mei 3, ua manaʻo ka US Environmental Protection Agency e pāpā i ka hoʻohana ʻana i ka dichloromethane, i ʻike ʻia hoʻi ʻo dichloromethane, kahi mea hoʻoheheʻe maʻamau a me ke kōkua hana. Hoʻohana ʻia ia i nā ʻano noi mea kūʻai aku a me nā ʻoihana like ʻole, me nā mea hoʻopili a me nā mea hoʻopaʻa, nā huahana kaʻa, a me nā mea wehe pena a me nā uhi. Hana ʻia ka kemika i nā nui he nui - ma waena o £100 miliona a me £500 miliona mai 2016 a i 2019, e like me ka Chemical Data Report (CDR) - no laila, inā hala ka pāpā, e loaʻa ka hopena nui i nā ʻoihana he nui.
Ke kamaʻilio nei ka manaʻo o ka EPA i "ka pilikia kūpono ʻole i ke olakino kanaka a ka dichloromethane e kau ai ma lalo o nā kūlana o ka hoʻohana ʻana, e like me ka mea i hoʻopaʻa ʻia ma nā wehewehe pilikia EPA ma lalo o ke kānāwai Toxic Substances Control Act (TSCA)". Ka loiloi pilikia TSCA a me ka hoʻopili ʻana i nā koi i ka nui e pono ai e hōʻoia i ka ʻole o ka pilikia kūpono ʻole o ka kemika.
Eia kekahi, koi ke kānāwai i manaʻo ʻia e ka EPA i kahi Hoʻolālā Palekana Hana Kemika (WCPP), nona nā koi hoʻokō no nā palena hōʻike hanu a me ka nānā ʻana i ka hōʻike no kekahi mau hoʻohana mau ʻana o ka methylene chloride. E kau pū ia i nā koi mālama moʻolelo a me nā koi hoʻolaha ma hope no kekahi mau kūlana hoʻohana a hāʻawi i kekahi mau ʻokoʻa manawa palena i nā koi hoʻohana e hiki ai ke hōʻeha nui i ka palekana aupuni a me nā ʻoihana koʻikoʻi.
ʻO nā ʻoihana e hana ana, lawe mai, hana, hāʻawi pāʻoihana ana, hoʻohana a hoʻolei paha i ka methylene chloride a i ʻole nā ​​​​huahana i loaʻa ka methylene chloride e hiki ke hoʻopilikia ʻia e ke kānāwai i manaʻo ʻia. Aia ma ka lula i manaʻo ʻia he papa inoa ma mua o 40 mau ʻano ʻoihana like ʻole e hiki ke uhi ʻia e ke kānāwai, me: ke kūʻai nui ʻana o nā kemika, nā kikowaena aila a me nā kikowaena, ka hana ʻana o nā kemika organik a me nā inorganic maʻamau, ka hoʻolei ʻōpala weliweli, ka hana hou ʻana i nā mea, ka pena a me ka pena. nā mea hana; nā ʻoihana plumbing a me ke ea hoʻoluʻu; nā ʻoihana pena a me ka hoʻopili ʻana i ka pepa paia; nā hale kūʻai ʻāpana kaʻa a me nā mea pono; ka hana ʻana o nā lako uila a me nā ʻāpana; ka hana ʻana o nā lako soldering; nā mea kūʻai aku o nā kaʻa hou a me nā kaʻa i hoʻohana ʻia; nā lawelawe hoʻomaʻemaʻe maloʻo a me ka holoi lole; ka hana ʻana i nā pēpē, nā mea pāʻani a me nā pāʻani.
ʻŌlelo ke kānāwai i manaʻo ʻia "Ma kahi o 35 pakeneka o ka hana makahiki o ka methylene chloride e hoʻohana ʻia no nā kumu lāʻau lapaʻau ʻaʻole i pili i ka TSCA a ʻaʻole i pili i kēia kānāwai." i hoʻokaʻawale ʻia mai ka wehewehe ʻana o "kemika" ma nā ʻāpana liʻiliʻi (B)(ii) a i (vi). ʻO kēia mau hoʻokuʻu "e komo pū me ... kekahi meaʻai, mea hoʻohui meaʻai, lāʻau lapaʻau, mea hoʻonani, a mea hana paha, e like me ka mea i wehewehe ʻia ma ka Pauku 201 o ke Kānāwai Meaʻai, Lāʻau Lapaʻau, a me nā Mea Hoʻonani Pekelala, i ka wā i hana ʻia ai, hana ʻia, a hāʻawi ʻia paha no ka hoʻohana ʻana ma ke ʻano he lāʻau lapaʻau. , nā mea hoʻonani a i ʻole nā ​​mea hana..."
No kēlā mau ʻoihana e hoʻopilikia ʻia e kēia pāpā, he mea nui e hoʻomaka e ʻimi i nā koho ʻē aʻe. Ua ʻike ka loiloi a ka EPA i nā koho ʻē aʻe i ka methylene chloride i nā koho ʻē aʻe no nā ʻano hana like ʻole e like me nā mea hoʻopili, nā mea hoʻopaʻa, nā mea hoʻohemo momona, nā mea wehe pena a me nā uhi, nā mea hoʻopaʻa, a me nā lubricants a me nā greases. Eia nō naʻe, pono e hoʻomaopopo ʻia ʻaʻohe mea pani no nā mea hoʻohui ʻenehana (me nā mea ʻē aʻe) i loaʻa. ʻAʻole ʻōlelo ka loiloi o nā koho ʻē aʻe "i nā huahana e hoʻohana ʻia ma kahi o dichloromethane; akā, ʻo kāna kumu ka hāʻawi ʻana i kahi papa inoa koho o nā huahana ʻē aʻe a me nā mea kemika a me ko lākou mau pōʻino e pili ana me dichloromethane, e hōʻoia i ka manaʻo ʻia ʻana o nā hopena o ka hoʻāʻo ʻana i nā koho ʻē aʻe he ʻāpana o nā lula TSCA Section 6(a) no methylene chloride. " Pono e loaʻa nā manaʻo ma ke kānāwai i manaʻo ʻia ʻaʻole ma hope o Iulai 3 a loaʻa ma ka puka uila federal electronic rulemaking ma https://www.regulations.gov.
ʻŌlelo Hoʻokuʻu: Ma muli o ke ʻano maʻamau o kēia mea hou, ʻaʻole paha e pili ka ʻike i hāʻawi ʻia ma ʻaneʻi i nā kūlana āpau, a ʻaʻole pono e hana ʻia me ka ʻole o ka ʻōlelo aʻoaʻo kānāwai kikoʻī e pili ana i kou kūlana kikoʻī.
