Port Of Seattle internal memo dated 04/30/01 from Beth Clark to Paul Agid (cc: Elizabeth Leavitt, Jim Thomson) regarding rock aggregate imported from the Black River Quarry (King County, Washington), owned by Stoneway Rock & Recycling, used in the Third Runway embankment during August–October 2000.

A Port of Seattle memo from April 2001 summarizes environmental testing of rock aggregate imported from the Black River Quarry for use in the Third Runway embankment project. Testing by environmental consultant AMEC found petroleum hydrocarbons (TPH) and elevated copper levels in some samples, prompting operational changes at the quarry including equipment cleaning and discarding the first hundred tons of rock after asphalt recycling operations. Follow-up testing confirmed that contaminant levels fell below MTCA Method A cleanup standards, and the Port halted material imports from the quarry in mid-October 2000 pending resolution.

In this April 2001 letter, Northwest Hydraulic Consultants raised technical concerns on behalf of the Airport Communities Coalition regarding a proposed NPDES permit modification for Seattle-Tacoma International Airport. The firm identified two key issues: a lack of clear, enforceable design criteria for stormwater overflows from the airport's integrated wastewater system (IWS), and an inconsistency between the permit's stormwater detention standards and the stricter standards sought under Section 401 Certification for the Third Runway and Master Plan Update projects. The consultants recommended that the permit be revised and republished for public comment to address these gaps and ensure consistent, enforceable stormwater management requirements.
