Aha biro 20 by’okwezi kwa kana 2023, ekitongore ky’okurinda eby’obuhangwa ekya America (EPA) kikataho ekiragiro ekirikuzibira munonga okukora, okukora, n’okujanjaaza methylene chloride omu by’obushuubuzi. EPA neekozesa obushoboorozi bwayo ahansi y’ekicweka kya 6(a) eky’ebiragiro ebirikukwata aha by’obutwa (TSCA), ebirikwikiriza ekitongore eki kutaho okuzibira nk’okwo aha by’emibazi. Akabi k‘okuhutaara nari embeera etaine nshonga. Methylene chloride neekira kukozesebwa nk’ekirungo omu bikwatiraine n’okuhamya n’okukinga, ebintu by’emotoka, n’ebintu ebirikuihaho erangi n’ebintu ebirikugijwara, kandi amakorero nk’emotoka, emibazi, n’emibazi nibibaasa kukwatwaho ekiragiro eki.
Ekiteiso kya EPA nikishaba okuzibira okukozesa methylene chloride omu mirimo mingi ey’amakorero n’eby’obushuubuzi. Ekiteiso eki kirimu okushoroora, okukira munonga okuihaho erangi n’ebintu ebirikukoresibwa omu kitongore ky’enyonyi z’abantu buntu kumara emyaka 10 okwetantara okushiisha munonga eby’okwerinda by’eihanga n’ebintu ebikuru. EPA nayo eyongyeire aha nkora egi ey’okutaho omu nkora ya NASA ey’ahonaaho ey’okukoresa dichloromethane omu mbeera ezimwe ezigumire nari ezigumire ezitariho emiringo endiijo ey’obukuumi omu by’obuhangwa nari omu by’entaasya.
Ekiteiso ky’ekitongore eki nikiija n’okuha orusa okukozesa dichloromethane kureetaho hydrofluorocarbon-32 (HFC-32), ekintu ekirikubaasa kukoresibwa kwongyera aha kuhinduka kuruga omu HFC ezindi ezirikugambwa kuba ziine obushoboorozi bw’okutagata kw’ensi yoona, ekirikuhagira okuteeraho kwa EPA okukyendeeza HFCs. okurugiirira aha biragiro bya US eby’okuhanga n’okukora ebintu bisya ebya 2020. Kwonka ekitongore eki nikiija kwetenga abakozi b’enyonyi z’abantu buntu, NASA, na HFC-32 kukuratira enteekateeka y’okwerinda emibazi ya methylene chloride omu myanya y’okukoreramu erimu obugarukiro oburikwetengwa obw’okukwatwaho n’okureeberera okurikukwatagana n’okukwatwaho. n’okuhuuta.
Ekiragiro ekirikuteekateekwaho kyaheza kushohozibwa omu kitabo kya gavumenti, EPA neija kwikiriza ebiteekateeko by’abantu aharikyo kumara ebiro 60 aha rules.gov/docket/EPA-HQ-OPPT-2020-0465.
