Peb tej nkev tis lawv muaj xws li ntau tshaj 40,000 mais ntawm tis pipelines thiab ntau tshaj 6,000 mais ntawm tsheb thauj mus los pipelines. Tus pipelines muab kev pab rau ntawm 4.2 lab (million) cov neeg muas zaub los ntawm Bakersfield rau ciam teb Oregon ciam teb.
Yim roj compressor noj tseem ceeb heev rau peb lub cev. Cov noj tau txais, khw thiab txav tej nkev los ntawm tuam txhab pipelines. Ze li ntawm 40 feem pua ntawm peb tej nkev mov nkag mus rau lawv ntawm peb Topock Compressor chaw nres tsheb, uas yog nyob 15 mais southeast ntawm Needles, California.

Thaum ntawd, ib additive uas muaj hexavalent chromium yog siv ntawm ob noj kom tiv thaiv rust hauv lub cooling towers.
Cov dej txias uas muaj nyob no additive yog pov tseg rau tom ntej no rau lub compressor noj. Qhov no yog zoo ib yam nrog kev lag luam xyaum lub sij hawm. Tom qab, cov dej ntawd kho kom tshem cov chromium ua ntej pov tseg. Peb tau ntev lawm discontinued siv hexaval chromium ntawm Topock thiab Hinkley. Raws li cov kev taw qhia ntawm lub xeev thiab tsoom fwv teb chaws cov koom haum ntxawg, thiab nrog input ntawm stakeholders, peb ua hauj lwm los soj ntsuam, ntxuav thiab restore lub chaw ntawm lub Topock thiab Hinkley chaw.
