ROCK SPRINGS, Wyo. (AP) — Chevron USA Inc. has gotten the go ahead to add up to 88 new wells in western Wyoming.

The U.S. Bureau of Land Management Wednesday said it authorized Chevron to expand Table Rock Field 40 miles east of Rock Springs. The plan calls for 33 shallow new oil wells and 20 deep gas wells, and as many as 35 water injection wells. Chevron also got approval to convert 18 existing wells to water injection wells.

The BLM says just over 300 acres would be disturbed and the wells would have a lifespan of between 40 and 55 years.

Public comment on the plan began in November and the BLM says all concerns have been addressed in the environmental assessment.
