Imithetho emitsha ye-Arhente yoKhuseleko lweNdalo ijolise ekuthinteleni ungcoliseko lomoya oluyingozi oluvela kubenzi bentsimbi baseMelika ngokunciphisa ungcoliseko olufana ne-mercury, i-benzene kunye ne-lead ebezisoloko zityhefa umoya kwiindawo ezingqonge izityalo.
Le mithetho ijolise kwizinto ezingcolisayo ezikhutshwa zii-oveni ze-coke zezakhiwo zentsimbi. Igesi evela kwii-oveni idala umngcipheko womhlaza womntu ngamnye emoyeni ojikeleze izityalo zentsimbi ezingama-50 kwi-1,000,000, nto leyo abameli bezempilo yoluntu bathi iyingozi ebantwaneni nakubantu abaneengxaki zempilo ezifihlakeleyo.
Ezi khemikhali azihambi kude nesityalo, kodwa abameli bazo bathi ziye zayitshabalalisa impilo yoluntu kwiindawo ezinabantu abanengeniso ephantsi “ezijikeleze izakhiwo zentsimbi”, kwaye zimela umba wobulungisa bendalo.
“Abantu kudala bejongene nemingcipheko ebalulekileyo yempilo, njengomhlaza, ngenxa yongcoliseko lwe-coke oven,” utshilo uPatrice Simms, usekela-mongameli we-Earthjustice kwiindawo ezisempilweni. Le mithetho “ibalulekile ekukhuseleni uluntu kunye nabasebenzi abakufutshane nee-coke ovens”.
Ii-oven zeCoke ziigumbi ezifudumeza amalahle ukuze kuveliswe i-coke, inkunkuma eqinileyo esetyenziselwa ukwenza intsimbi. Igesi eveliswa zii-oven ihlelwa yi-EPA njengesifo somhlaza esaziwayo ebantwini kwaye iqulethe umxube weekhemikhali eziyingozi, iintsimbi ezinzima kunye neekhompawundi eziguquguqukayo.
Uninzi lweekhemikhali lunxulunyaniswa neengxaki zempilo ezinzulu, kuquka i-eczema enzima, iingxaki zokuphefumla kunye nezilonda zokugaya ukutya.
Phakathi kobungqina obandayo bobutyhefu begesi kwiminyaka yakutshanje, i-EPA ayizange yenze nto ingako ukulawula ungcoliseko, batsho abagxeki. Amaqela okusingqongileyo ebesoloko enyanzelisa imida emitsha kunye nokubeka esweni ngcono kwaye ubulungisa boMhlaba ngo-2019 bamangalela i-EPA ngale ngxaki.
Ii-oveni zeCoke ziye zabangela iingxaki ezinkulu kwizixeko ezikwimimandla yemizi-mveliso ephezulu yase-midwest nase-Alabama. EDetroit, umzi-mveliso weCoke oye waphula imigangatho yomgangatho womoya kangangeminyaka emininzi uphakathi kwetyala eliqhubekayo elityhola abemi abakufutshane ukuba bagule kwindawo enabantu abamnyama kakhulu, nangona imithetho emitsha ingagubungeli loo nto ingcolisayo.
Le mithetho, eyapapashwa ngoLwesihlanu, ifuna uvavanyo "locingo" olujikeleze izityalo, kwaye, ukuba kufunyenwe ukuba into engcolileyo idlula imida emitsha, abenzi bentsimbi kufuneka bachonge umthombo kwaye bathathe amanyathelo okwehlisa amanqanaba.
Le mithetho ikwasusa iindlela ezingasetyenziswanga ngaphambili kushishino ukuze kuthintelwe ukuxela ukukhutshwa komoya ongcolileyo, njengokungavumeli imida yokukhutshwa komoya ongcolileyo ngexesha lokungasebenzi kakuhle.
Uvavanyo ngaphandle kwesityalo sasePittsburgh esiqhutywa yi-US Steel, enye yezona mveliso zinkulu zelizwe, lufumanise amanqanaba e-benzene, i-carcinogen, aphezulu ngokuphindwe kalishumi kunemida emitsha. Isithethi se-US Steel sixelele i-Allegheny Front ukuba imithetho ayinakwenzeka ukuba isetyenziswe kwaye iya kuba "neendleko ezingazange zibonwe ngaphambili kunye nefuthe elibi elingalindelekanga kwindalo esingqongileyo".
“Iindleko bezingenakubonwa ngaphambili kwaye bezingaziwayo kuba akukho teknoloji ziqinisekisiweyo zokulawula ezinye izinto ezingcolisa umoya ezinobungozi,” utshilo isithethi.
U-Adrienne Lee, igqwetha le-Earthjustice, uxelele i-Guardian ukuba lo mthetho usekelwe kwidatha yeshishini enikwe i-EPA, kwaye waphawula ukuba le mithetho ngokubanzi ayizukunciphisa ukukhutshwa komoya, kodwa iya kuthintela ukugqithiswa komoya.
“Ndikufumanisa kunzima ukukholelwa ukuba [imida] iya kuba nzima ukuyifikelela,” utshilo uLee.
