Comments sought on Kent site investigation and cleanup options


Proposed cleanup strategies for contaminated areas beneath a hazardous waste processing facility in Kent could include an underground barrier, on-site groundwater treatment or long-term monitoring.

The Washington Department of Ecology seeks public comment through Nov. 14, 2017, on an evaluation of cleanup options for Stericycle/BEI (formerly PSC, operating as Burlington Environmental LLC) at 20245 77th Ave. S.

Ecology also seeks comment on an earlier investigation that determined the type and extent of the site’s contamination. A variety of contaminants are located within Stericycle’s property and pose no immediate risk to human health or the environment.

People also can comment on amendments Ecology proposes to the facility’s state permit to treat and temporarily store hazardous wastes. The changes would include closing some operations and transferring them to the company’s Tacoma facility, closure of several oily wastewater tanks and construction of several facility upgrades.

Hundreds of manufacturers and other businesses – in Washington and elsewhere in the West – rely on Stericycle for proper treatment, storage and disposal of their hazardous wastes. The Kent facility processes oily wastewater, materials that contain polychlorinated biphenyls, acids, cyanide wastes, sludges, phenols, caustic materials, and aqueous metal-bearing wastes.
