This document, marked as Leytham Exhibit 222 (dated 2/11/02), contains a hand-drawn diagram illustrating flow rate over time, showing the relationship between minute and hourly measurements alongside an infiltration capacity curve. The sketch plots flow rate on the vertical axis against time intervals (15, 30, 45, 60 minutes) on the horizontal axis, with a shaded area indicating peak flow. It appears to be a technical exhibit related to stormwater or drainage analysis presented in proceedings concerning Sea-Tac Airport policy.

Stipulation and Agreed Order filed February 8, 2002, in Pollution Control Hearings Board case PCHB No. 01-160, involving Airport Communities Coalition (ACC) and Citizens Against Airport Expansion as appellants against State of Washington Department of Ecology and Port Of Seattle as respondents, concerning Clean Water Act Section 401 Certifications #1996-4-02325 and #1996-4-02325 (Amended-1). Parties including

Port Of Seattle’s Motion for Partial Summary Judgment filed in PCHB Case No. 01-160 before the Pollution Control Hearings Board for the State of Washington, opposing ACC (Airport Communities Coalition) claims that Ecology’s 401 Certification is invalid due to SEPA non-compliance. The motion argues six independent grounds for dismissal of Agreed Issue No. 14 (‘Did

Declaration of Michael Feldman, Director of Aviation Facilities and Environmental Programs at Port Of Seattle, filed in PCHB Case No. 01-160 (Airport Communities Coalition v. Department of Ecology and Port Of Seattle). Feldman attests to the history of environmental review for the Sea-Tac Airport Master Plan Update, including the 1996 FEIS, May 1997 SEIS, FAA

This declaration by Paul Fendt, a licensed civil engineer with over 18 years of stormwater experience, was submitted in support of the Port of Seattle's opposition to the Airport Communities Coalition's motion in a 2001 Washington Pollution Control Hearings Board case. Fendt explains how new airport development and impervious surfaces can impact local waterways by increasing runoff and reducing groundwater recharge, and describes the stormwater management systems required by the Washington Department of Ecology for the Port of Seattle's Master Plan Update projects. The document provides technical background on stormwater best management practices (BMPs) and regulatory requirements under Washington State and federal Clean Water Act permits.

An email dated February 8, 2002, from Peter Willing to John Strand reports turbidity measurements taken during a site visit at Sea-Tac on January 28, 2002, between 11:45 and 12:08. Two samples were recorded: Sample #1 showed tank farm outfall at 281 NTU and DM Creek at 31 NTU, while Sample #2 showed tank farm outfall at 299 NTU and DM Creek at 31.2 NTU. The data indicates significantly elevated turbidity levels at the tank farm outfall compared to the creek reference point.

A February 2002 letter from Marten Brown attorneys transmits two spreadsheets listing reference documents used by expert witness John Strunk in the case ACC and CASE v. Port of Seattle and Department of Ecology (PCHB No. 01-160). The spreadsheets catalog technical reports and studies related to preferential ground water flow paths near the proposed Third Runway at Seattle-Tacoma International Airport, covering sites such as airline fuel farms, maintenance hangars, and contaminated ground water areas. Documents were produced by environmental consultants including Associated Earth Sciences and EMCON, spanning reports from the mid-1990s through 2001.

This document (AR 019657) is a site map of an active construction area at what appears to be Sea-Tac Airport, showing a restricted AOA (Air Operations Area) zone, embankments, and Lagoon 3. Handwritten annotations reference two stockpiles dated 1997 and 1999, with approximate volumes of 400,000 cubic yards and 2,100,000 cubic yards respectively. The map was entered as Exhibit 284 on 2/7/02, with witness Clark and court reporter Diane Mills.

A February 2002 technical letter from GeoSyntec Consultants, written on behalf of the Airport Communities Coalition, raises concerns about the Port of Seattle's low flow analysis for the Sea-Tac Airport Third Runway expansion project. The letter argues that the Port's analysis fails to account for the years-long delay before water would flow through the new embankment fill into drainage systems feeding nearby creeks, potentially leaving those creeks without adequate water during the critical early years of operation. GeoSyntec concludes that the Port has not demonstrated the project's storage vaults are properly sized, and that the underlying computer models are unreliable due to lack of calibration and flawed assumptions about soil hydraulic conductivity.

This is a National Pollutant Discharge Elimination System (NPDES) waste discharge permit issued by the Washington State Department of Ecology to Cascade Pole and Lumber Company, a wood preserving facility in Tacoma, Washington. The permit, valid from March 2002 to March 2007, authorizes the company to discharge treated stormwater and process wastewater into the Blair Waterway and Puyallup River, subject to strict discharge limits, monitoring requirements, and pollution prevention measures. Note: this document pertains to water quality regulation and does not contain information related to Sea-Tac Airport noise policy.
