Ma nā lula i manaʻo ʻia i paʻi ʻia ma Mei 3, ua manaʻo ka EPA e pāpā i ka hapa nui o ka hoʻohana ʻana o 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, 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 paona ma waena o 2016 a me 2019, e like me ka Chemical Data Report (CDR) - no laila, inā e hala ka pāpā, e loaʻa nā hopena nui no nā ʻoihana he nui. He hopena nui. keʻena.
Ke kamaʻilio nei ka manaʻo o ka EPA i "kahi pilikia kūpono ʻole o ka hōʻeha i ke olakino kanaka mai ka dichloromethane 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)". a i ʻole ke kaiapuni i ʻike ʻia ma ka loiloi pilikia TSCA a hoʻopili i nā koi i ka nui e pono ai i ʻole e hoʻokau hou nā kemika i kahi pilikia kūpono ʻole.
Eia kekahi, koi ke kānāwai i manaʻo ʻia e ka EPA i kahi Hoʻolālā Palekana Hana Kemika (WCPP), nona nā koi no ka mālama ʻana i nā palena o ka hoʻohuihui hanu a me ka nānā ʻana i ka ʻike ʻana no kekahi mau kūlana o ka hoʻohana mau ʻana o ka dichloromethane. E kau pū ia i nā koi mālama moʻolelo a me ka hoʻolaha ma hope no kekahi mau kūlana o ka hoʻohana ʻana a hāʻawi i kekahi mau ʻokoʻa manawa palena ʻia 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, 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. ʻOi aku ka papa inoa o ke kānāwai i manaʻo ʻia ma mua o 40 mau ʻano ʻoihana like ʻole i hiki ke kau ʻia ma lalo o ke kānāwai, me: ke kūʻai nui ʻana o nā kemika; nā kikowaena hoʻouka aila a me nā kikowaena; ka hana ʻana o nā kemika organik a me nā inorganic maʻamau; ka hoʻolei ʻana i nā ʻōpala weliweli; nā ʻoihana no ka hana ʻana i nā mea; nā pena a me nā pena. nā mea hana; nā ʻoihana plumbing a me nā ea hoʻoluʻu; nā ʻoihana pena a me ka uhi ʻana i ka 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 wili a me ke kūʻai ʻana; nā mea kūʻai aku o nā kaʻa hou a me nā mea i hoʻohana ʻia; nā lawelawe hoʻomaʻemaʻe maloʻo a me ka holoi lole; a me nā pēpē, nā mea pāʻani a me nā pāʻani. hana.
ʻŌlelo ke kānāwai i manaʻo ʻia "Ma kahi o 35 pakeneka o ka hana makahiki methylene chloride i hoʻohana ʻia no nā kumu lāʻau lapaʻau a ʻaʻole i kau ʻia a hoʻoponopono ʻia paha e ka TSCA." )( B) ʻO kēlā me kēia mea ʻē aʻe ma mua o ka wehewehe ʻana o "kemika" ma nā paukū (ii)-(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 Federal, i hana ʻia, hana ʻia, a kūʻai ʻia paha ma ke ʻano he meaʻai, mea hoʻohui meaʻai, lāʻau lapaʻau, mea hoʻonani a mea hana paha..."
No kēlā mau ʻoihana e hoʻopilikia ʻia e kēia pāpā, he mea nui e hoʻomaka e noʻonoʻo e pili ana i nā koho ʻē aʻe. Ua ʻike ka loiloi a ka EPA i nā koho ʻē aʻe i ka hoʻohana ʻana 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.
