Environmental Services in Spokane, WA

MTCA, administered by the Washington Department of Ecology, sets cleanup standards and liable-party rules that are often more stringent than federal CERCLA requirements. Even when federal oversight does not apply, a Washington property transaction or redevelopment project may trigger MTCA obligations. Our Phase I and Phase II work is scoped with MTCA regulatory context in mind, so findings are framed in terms relevant to Washington State agency review and cleanup threshold evaluation.

Spokane's industrial history means Phase I site reconnaissance frequently identifies historical railroad corridor proximity, petroleum product storage associated with warehousing and distribution, and dry-cleaning solvent release sites, particularly chlorinated compounds such as PCE and TCE. Agricultural chemical storage is also a factor on sites transitioning from rural to commercial use in outlying areas of the Spokane Valley. These patterns inform how we scope Phase II investigations and what analytes we prioritize.

Yes. Construction-phase environmental support includes soil screening during excavation, documentation of suspect materials, and field decisions about whether encountered conditions require regulatory notification under MTCA. Unexpected finds during grading or utility trenching are not uncommon on infill and redevelopment sites. Having an environmental professional available during earthwork reduces schedule risk and supports defensible decision-making if a regulatory contact becomes necessary.

Field work in Spokane is dispatched through the Seattle, WA regional hub, about 228 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Spokane projects.
