YAKIMA, Wash. (AP) — Environmental officials have asked for public comment on plans to clean up more than a dozen polluted sites at the U.S. Army’s training center in Yakima.

The state Department of Ecology said the plans address 21 different areas on the base that do not meet federal soil and groundwater standards for pollution or have yet to be investigated.

The deadline for submitting public comments is Sept. 16. The satellite garrison of Joint Base Lewis-McChord has been used since 1941 to provide combat training for troops, which resulted in disposed ammunition, lead-acid batteries, fuel, solvents and other pollutants.
