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.

The consultants recommended that the permit be revised and republished for public comment to address these gaps and ensure consistent, enforceable stormwater management requirements.
