o te tau 1989. I te 24 o Poutu-te-rangi, ka rere te kaipuke hinu "Exxon Valdez" ki Prince William Sound, e 11 miriona karetao hinu raw ki roto i te wai, e hora ana i te 1,100 maero (1,800 kiromita) o te takutai. E ai ki te U.S. Fish and Wildlife Service, e 300,000 ngā manu moana, e 2,000 ngā otter, me ētahi atu kararehe moana i mate i te ngaronga. I whakapauhia e Exxon US $ 2 piriona ki te horoi i te tau tuatahi anake. Ko Exxon, e mahi tahi ana me nga tari kawanatanga me nga tari kawanatanga, i haere tonu ki te horoi i te timatanga o nga tau 1990. E whakaatu ana ngā rangahau a te kāwanatanga, nā te hinu me te tukanga horoi ake i kino te wā roa ki te rauropi o te Sound, e whakararuraru ana i te whakatipuranga o ngā manu me ngā kararehe i runga i ngā huarahi kāore anō kia tino mārama. Te āhua nei kua ora ake a Prince William Sound, engari kei te tautohetia tonutia e ngā pūtaiao te whānuitanga o te whakaora. I roto i tētahi whakataunga ā-iwi, i whakaae a Exxon ki te utu i te $900 miriona i roto i ngā utu ā-tau tekau, ā, $100 miriona anō mō ngā ngaronga hou i kitea. I roto i te whakawa a te roopu ki a Exxon, i whakawhiwhia e te kaunihera he utu mo te US $ 5 piriona, engari mai i te tau 2008 kaore ano kia utua he moni, kei te haere tonu te whakawakanga.
