EXH AR025049: Draft 401 Certification — Acceptable Fill Criteria & Prohibited Fill Material Language (July 30, 2001)

This July 2001 draft document outlines clean fill criteria for the Port of Seattle's Third Runway construction project at Sea-Tac Airport, requiring the Port to submit environmental assessment documentation to the Washington Department of Ecology before placing any fill material. It specifies that fill may only come from state-certified borrow pits, contractor-certified construction sites, or Port-owned properties, while prohibiting the use of any contaminated or remediated soils. The document details testing and sampling requirements, including review of contamination records and analysis of hazardous substances, to ensure that no toxic materials are introduced into wetlands or state waters during construction.
