The Airport Communities Coalition (ACC) — representing the cities of Burien, Des Moines, Federal Way, Normandy Park, and Tukwila, plus the Highline School District — filed a formal appeal in August 2001 challenging Washington State's approval of environmental permits for Seattle-Tacoma International Airport's proposed third runway. The appeal targets the Department of Ecology's Clean Water Act Section 401 Certification and Coastal Zone Management Act concurrency statement, both issued on August 10, 2001. ACC argued that the Port of Seattle's application contained scientific flaws and insufficient information to protect local waterways such as Des Moines Creek and Miller Creek that run through the surrounding communities.

Airport Communities Coalition (ACC) — comprising Cities of Burien, Des Moines, Federal Way, Normandy Park, Tukwila, and Highline School District — filed this Notice of Appeal with the Pollution Control Hearings Board (PCHB) on August 23, 2001, challenging Ecology’s August 10, 2001, issuance of Clean Water Act Section 401 Certification No. 1996-4-02325 and accompanying Coastal

In August 2001, paralegal Andrea Grad of Helsell Fetterman submitted a Public Disclosure Act request to Washington State Department of Ecology seeking all documents related to the Sea-Tac Airport third runway project's consistency with the Coastal Zone Management (CZM) Program. Ecology's Ann Kenny responded that all relevant CZM documents had already been provided, noting that CZM and Section 401 water quality matters were handled together with no separate files, and that previously withheld deliberative documents had been released. Kenny also indicated she was still checking with other staff to determine if any additional materials had been overlooked.

In this August 3, 2001 email, Andrea Grad, a paralegal at Helsell Fetterman, submits a Public Disclosure Act (PDA) request to Ann Kenny at the Washington State Department of Ecology. Grad notes that several sections of the Port of Seattle's two-volume Low Flow Analysis — including the Introduction and the section on Determination of Impacts to Streamflow — were either incomplete or entirely missing from the copy provided by Ecology. She asks Ecology to confirm whether the Port had submitted the missing sections, and requests copies of any such materials.

This 2001 User's Guide from the Washington State Department of Ecology explains how to use spreadsheet workbook tools (MTCASGL and MTCATPH) to calculate soil and groundwater cleanup levels under the Model Toxics Control Act. The guide covers how to enter site-specific data—such as chemical properties, exposure parameters, and hydrogeological characteristics—to determine safe contamination thresholds. It is intended for environmental cleanup professionals working on hazardous substance remediation in Washington State.

This 2001 User's Guide from the Washington State Department of Ecology describes software workbook tools (MTCASGL and MTCATPH) designed to help calculate soil and ground water cleanup levels under the Model Toxics Control Act. The guide covers installation, technical requirements, and step-by-step instructions for entering site-specific data such as chemical properties, exposure parameters, and hydrogeological characteristics. Note that while this document addresses environmental cleanup standards, it does not appear to be directly related to Sea-Tac Airport noise policy.

Deliberative memorandum dated August 1, 2001 from Katie Walter (KLW@shanwil.com) to Ann Kenny, Washington State Department of Ecology, re Draft 401 Conditions for Auburn Mitigation Site revisions. Covers culvert placement issues in revised grading plan (June 28, 2001) at northwest corner and south central portion of site, drainage swale, maintenance pathway, and southwestern basin.

Handwritten notes dated 7/31/01 from Kelly Whiting discuss water quality treatment options for a downstream area, referencing NEPL and CARBO systems with treatment rates of 40% and 10% respectively. The notes cover spill containment and oil management considerations, including gravity oil-water separators and spill containment vaults upstream. A follow-up note from 7/31/01 indicates water quality issues will have comments, with discussion of impact numbers from a 7/23 report.
