Zomera zopitilira 200 zopanga mankhwala padziko lonse lapansi - kuphatikiza ambiri ku Texas m'mphepete mwa Gulf Coast - zidzafunika kuchepetsa mpweya wapoizoni womwe ungayambitse khansa kwa anthu omwe amakhala pafupi ndi lamulo latsopano la Environmental Protection Agency lomwe lalengeza Lachiwiri.
Malowa amagwiritsa ntchito mankhwala owopsa popanga mapulasitiki, utoto, nsalu zopangira, mankhwala ophera tizilombo ndi zinthu zina za petrochemical.Mndandanda wa EPA umasonyeza kuti pafupifupi 80, kapena 40% ya iwo, ali ku Texas, makamaka m'mizinda ya m'mphepete mwa nyanja monga Baytown, Channelview, Corpus Christi, Deer Park, La Porte, Pasadena ndi Port Arthur.
Lamulo latsopanoli likugogomezera kuchepetsa mankhwala asanu ndi limodzi: ethylene oxide, chloroprene, benzene, 1,3-butadiene, ethylene dichloride ndi vinyl chloride.Zonse zimadziwika kuti zimawonjezera chiopsezo cha khansa ndikuyambitsa kuwonongeka kwa mitsempha, mtima ndi chitetezo cha mthupi pambuyo powonekera kwa nthawi yaitali.
Malinga ndi EPA, lamulo latsopanoli lidzaphwanya matani oposa 6,000 a mpweya wapoizoni pachaka ndikuchepetsa chiwerengero cha anthu omwe ali ndi chiopsezo chachikulu cha khansa ndi 96% m'dziko lonselo.
Lamulo latsopanoli lidzafunanso kuti malo aziyika zida zowunikira mpweya zomwe zimayesa kuchuluka kwa mankhwala omwe ali pamalo opangira malo.
Titha kupereka ma sensor a gasi amitundu yambiri omwe amatha kuyang'anira mitundu yosiyanasiyana ya mpweya
Harold Wimmer, pulezidenti ndi mkulu wa bungwe la American Lung Association, ananena kuti anthu oonera mpweya “athandiza kuteteza madera apafupi powapatsa chidziwitso cholondola chokhudza mpweya umene amapuma.”
Kafukufuku akuwonetsa kuti madera amitundu ndi omwe amakhala pachiwopsezo choipitsidwa ndi mafakitale opanga mankhwala.
Cynthia Palmer, katswiri wamkulu wa petrochemicals ndi bungwe lopanda phindu la Moms Clean Air Force, adanena m'mawu olembedwa kuti lamulo latsopanoli "ndilofunika kwambiri kwa ine.Mnzanga wapamtima anakulira pafupi naini mwa malo kupanga mankhwala ku Texas kuti adzaphimbidwa mu rulemaking latsopanoli.Anamwalira ndi khansa pamene ana ake anali kusukulu.”
Palmer adati lamulo latsopanoli ndi gawo lofunikira kwambiri pakuchita chilungamo kwa chilengedwe.
Chilengezo cha Lachiwiri chimabwera patatha mwezi umodzi kuchokera pamene EPA idavomereza lamulo lochepetsa mpweya wa ethylene oxide m'malo ogulitsa malonda.Ku Laredo, anthu akuti zomera zotere zathandizira kuti anthu azidwala khansa mumzindawu.
Hector Rivero, pulezidenti ndi CEO wa Texas Chemistry Council, adanena mu imelo kuti lamulo latsopano la EPA lidzakhudza kwambiri kupanga ethylene oxide, yomwe adanena kuti ndi yofunika kwambiri pazinthu monga magalimoto amagetsi ndi tchipisi ta makompyuta, komanso mankhwala ophera tizilombo.
Rivero adati bungweli, lomwe likuyimira malo opitilira 200 mumakampani opanga mankhwala, litsatira malamulo atsopano, koma akukhulupirira kuti momwe EPA idawonera kuopsa kwa thanzi la ethylene oxide inali yolakwika mwasayansi.
"Kudalira kwa EPA pazidziwitso zachikale zautsi kwapangitsa kuti pakhale lamulo lomaliza lotengera kuopsa kwachiwopsezo komanso phindu longoyerekeza," adatero Rivero.
Lamulo latsopanoli liyamba kugwira ntchito posakhalitsa litasindikizidwa mu Federal Register.Kuchepetsa kwakukulu kwa chiwopsezo cha khansa kudzabwera chifukwa chochepetsa kutulutsa kwa ethylene oxide ndi chloroprene.Malo ayenera kukwaniritsa zofunikira zochepetsera ethylene oxide patatha zaka ziwiri lamuloli likugwira ntchito ndipo ziyenera kukwaniritsa zofunikira za chloroprene pasanathe masiku 90 kuchokera tsiku logwira ntchito.
Mneneri wa bungwe loona za chilengedwe la boma la Texas Commission on Environmental Quality, Victoria Cann, adati bungweli lichita kafukufuku kuti liwone ngati likutsatiridwa ndi lamulo latsopanoli monga gawo la ndondomeko yake yotsatiridwa ndi kutsatiridwa.
Lamuloli limayang'ana zida zopangira mankhwala zomwe zimatulutsa mpweya woipa monga makina osinthira kutentha (zida zomwe zimatenthetsa kapena zamadzimadzi ozizira), komanso njira monga kutulutsa ndi kuyatsa komwe kumatulutsa mpweya mumlengalenga.
Kuwotcha kumachitika nthawi zambiri poyambira, kutseka ndi kulephera.Ku Texas, makampani adanenanso kuti atulutsa mapaundi 1 miliyoni oipitsidwa kwambiri panthawi yachisanu cha Januware.Othandizira zachilengedwe anena kuti zochitikazi ndizovuta pakusunga zachilengedwe zomwe zimalola kuti malo asokonezeke popanda chilango kapena chindapusa pamikhalidwe ina monga nyengo yoopsa kapena masoka achilengedwe.
Lamuloli limafuna kuti malo azipereka malipoti owonjezera omvera komanso kuwunika magwiridwe antchito pambuyo pazochitika zotere.
