Mu malamulo omwe adaperekedwa omwe adasindikizidwa pa Meyi 3, EPA idapereka lingaliro loletsa kugwiritsa ntchito kwambiri dichloromethane, yomwe imadziwikanso kuti dichloromethane, chosungunulira chofala komanso chothandizira kukonza. Imagwiritsidwa ntchito m'njira zosiyanasiyana zogulira ndi zamalonda, kuphatikiza zomatira ndi zotsekera, zinthu zamagalimoto, ndi zochotsa utoto ndi zokutira. Mankhwalawa amapangidwa mochuluka - pakati pa mapaundi 100 miliyoni ndi 500 miliyoni pakati pa 2016 ndi 2019, malinga ndi Chemical Data Report (CDR) - kotero chiletsocho, ngati chitavomerezedwa, chingakhale ndi zotsatirapo zazikulu pamafakitale ambiri. Izi zimakhudza kwambiri dipatimentiyi.
Cholinga cha EPA chikukhudza "chiwopsezo chosamveka bwino cha kuvulaza thanzi la anthu kuchokera ku dichloromethane pansi pa mikhalidwe yogwiritsidwa ntchito, monga momwe zalembedwera mu matanthauzidwe a chiopsezo cha EPA pansi pa Toxic Substances Control Act (TSCA)". kapena chilengedwe chomwe chatchulidwa mu TSCA risk assessment ndikugwiritsa ntchito zofunikira momwe zingafunikire kuti mankhwalawo asakhalenso pachiwopsezo chosamveka.
Kuphatikiza apo, lamulo lomwe laperekedwa ndi EPA likufuna Ndondomeko Yoteteza Malo Ogwirira Ntchito (WCPP), yomwe imaphatikizapo zofunikira kuti zitsatire malire a kuchuluka kwa mpweya wopumira komanso kuyang'anira momwe zinthu zilili pakugwiritsa ntchito dichloromethane mosalekeza. Idzakhazikitsanso zofunikira zosungira zolemba ndi zidziwitso zamtsogolo pazikhalidwe zingapo zogwiritsira ntchito ndikupereka nthawi zina zopatula pazofunikira zomwe zingayambitse kuvulaza kwakukulu chitetezo cha dziko ndi zomangamanga zofunika.
Makampani omwe amapanga, kutumiza kunja, kukonza, kugawa malonda, kugwiritsa ntchito kapena kutaya methylene chloride kapena zinthu zomwe zili ndi methylene chloride zitha kukhudzidwa ndi lamulo lomwe likuperekedwali. Lamulo lomwe likuperekedwali likutchula mitundu yoposa 40 ya mafakitale omwe angakhale pansi pa lamuloli, kuphatikiza: kugulitsa mankhwala ambiri; malo osungira mafuta ndi malo osungiramo zinthu; kupanga mankhwala oyambira achilengedwe ndi osapangidwa; kutaya zinyalala zoopsa; makampani okonza zinthu; utoto ndi utoto; opanga; makontrakitala a mapaipi ndi mpweya woziziritsa; makontrakitala opaka utoto ndi zokutira makoma; masitolo ogulitsa zida zamagalimoto ndi zowonjezera; kupanga zida zamagetsi ndi zigawo; kupanga zida zowotcherera ndi zosungunulira; ogulitsa magalimoto atsopano ndi ogwiritsidwa ntchito; ntchito zotsukira ndi kuchapa zovala; komanso zidole, zoseweretsa ndi masewera.
Lamulo lomwe likuperekedwali likunena kuti "Pafupifupi 35 peresenti ya kupanga methylene chloride pachaka imagwiritsidwa ntchito pazifukwa zamankhwala ndipo sikulamulidwa ndi TSCA." )(B) Chinthu chilichonse kupatula tanthauzo la "mankhwala" m'ndime (ii)-(vi). Zopanda izi "zikuphatikizapo ... chakudya chilichonse, chowonjezera pazakudya, mankhwala, zodzoladzola, kapena chipangizo, monga momwe zafotokozedwera mu Gawo 201 la Federal Food, Drug, and Cosmetic Act, chomwe chimapangidwa, kukonzedwa, kapena kugulitsidwa ngati chakudya, chowonjezera pazakudya, mankhwala, zodzoladzola kapena chipangizo…"
Kwa mafakitale omwe angakhudzidwe ndi chiletsochi, ndikofunikira kuyamba kuganizira za njira zina. Kuwunika kwa EPA kwa njira zina zogwiritsira ntchito methylene chloride kunapeza njira zina zogwiritsira ntchito zosiyanasiyana monga zomatira, zotsekera, zochotsera mafuta, zochotsa utoto ndi zokutira, zotsekera, ndi mafuta ndi mafuta. Komabe, ziyenera kudziwika kuti palibe njira zina zogwiritsira ntchito zowonjezera zaukadaulo (kuphatikizapo) zomwe zapezeka. Kuwunika kwa njira zina "sikulimbikitsa zinthu zomwe ziyenera kugwiritsidwa ntchito m'malo mwa dichloromethane; m'malo mwake, cholinga chake ndikupereka mndandanda woyimira wa zinthu zina ndi mankhwala ndi zoopsa zake poyerekeza ndi dichloromethane, kuti apereke kuwunika njira zina zomwe zingachitike. Zotsatira zake zimaonedwa ngati gawo la lamulo la TSCA Gawo 6(a) dichloromethane." Ndemanga pa lamulo lomwe likuperekedwali ziyenera kulandiridwa pasanathe pa Julayi 3 ndipo zikupezeka kudzera pa tsamba la federal electronic rulemaking pa https://www.regulation.gov.
Chodzikanira: Chifukwa cha mtundu wonse wa zosinthazi, zomwe zaperekedwa pano sizingagwire ntchito nthawi zonse, ndipo siziyenera kuchitidwa popanda upangiri walamulo kutengera momwe zinthu zilili.
