E ai ki ngā pūrongo i huri te Kamupene Hydro o Nōwei ki te hangarau whakakī maroke o ngā para bauxite hei whakakapi i te tāke para o mua, ā, nā reira ka pai ake te haumaru me te tiaki taiao o te mahi keri.
I te wā whakamātautau o tēnei otinga hou, i whakangaohia e Hydro tata ki te US$5.5 miriona ki te whakakorenga whakamutunga o ngā para i te rohe keri, ā, i whiwhi whakaaetanga whakahaere i tukuna e te tiwhikete Para State Secretariat for Environment and Sustainability (SEMAS).
I mea atu a John Thuestad, te Tumuaki Tuarua o te pakihi bauxite me te alumina a Hydro: "Kua whakapau kaha tonu a Hydro ki te whakatairanga i te whanaketanga pumau o te umanga konumohe, nō reira kua whakapau kaha mātou ki te whakatinana i tēnei nganatanga hei karo i te keri bauxite. Ko te whakatūnga o ngā puna paru hou pumau i te wā e keri ana ka puta he tūponotanga ki te taiao."
Ko te otinga a Hydro te ngana hou ki te whakakore i ngā para paru i roto i te umanga. Mai i te Hōngongoi 2019, kua whakamatautauria e Hydro tēnei hangarau i te maina paru Minerao Paragominas i te raki o te kawanatanga o Para. E mārama ana kāore te kaupapa e hiahia ki te hanga tonu i ngā tāke para hou, tae atu ki te tāpiri i ngā paparanga ki te hanganga tāke para o nāianei, nā te mea e whakamahi ana te kaupapa i tētahi tikanga e kiia nei ko te "whakakī anō i ngā para maroke". Arā, ko te whakakī anō i ngā para maroke kore mahi i roto i te rohe i keria.
Ko te wāhanga whakamātautau o tēnei otinga hou a Hydro e whakahaerehia ana i raro i te aroturukitanga me te aro turukitanga roa a ngā tari taiao, ā, e whai ana i ngā paerewa hangarau a te Komiti Taiao (Conama). Ko te whakamahinga o tēnei otinga hou i Brazil he taahiraa nui ki te whanaketanga tauwhiro, te whakapai ake i te haumaru mahi me te whakaiti i te tapuwae taiao a Hydro. I oti te whakamātautau kaupapa i te mutunga o te tau 2020, ā, i whakaaetia te mahi a te Para State Secretariat for Environment and Sustainable Development (SEMAS) i te 30 o Hakihea, 2020.
