Fax cover sheet and analytical lab reports sent by Rick Poulin of Smith & Lowney, P.L.L.C. (Seattle, WA) to Peter Eglick and Kevin Stock at Helsell Fetterman LLP on February 14, 2002, transmitting water sample lab results for Case 2, Site Visit Day 2. Enclosed letter from Analytical Resources, Incorporated (ARI), dated February 11, 2002,

This document presents a technical analysis of the effect of increasing water hardness on Fresh Water Acute Water Quality Standards, referencing WAC 173.201A.040. It includes calculated values for copper and zinc acute water quality criteria at varying hardness levels (ranging from 10 to 110 mg/L), showing how the allowable concentrations change as hardness increases. The document was transmitted via fax in February 2002 from Water Resources Consulting LLC.

This document is a February 2002 fax from Water Resources Consulting LLC addressing the effect of increasing water hardness on fresh water acute water quality standards, referencing WAC 173.201A.040. It contains tables calculating acute water quality standards for copper and zinc at varying hardness levels in fresh water. The document appears to be part of an administrative record (AR 021262) and was transmitted between consultants, though its connection to Sea-Tac Airport noise policy is not evident from the content.

A February 2002 analytical laboratory report from Analytical Resources, Inc. to Seattle law firm Smith & Lowney, documenting water sample testing results for a project referenced as Case 2. Four water samples were collected on January 31, 2002, and analyzed for metals, conventional parameters, and glycols, with the glycol analysis requiring re-testing due to calibration issues outside acceptable control limits. The results showed no detectable levels of ethylene glycol or propylene glycol above the 5.0 mg/L detection limit.

A February 2002 letter from Analytical Resources, Inc. to attorney Richard Poulin of Smith & Lowney, P.L.L.C. transmits laboratory analytical results for nine water samples accepted on January 28, 2002, under Case 1. The samples were received intact with no discrepancies noted on the chain of custody record, and analysis for requested parameters including glycols, TSS, copper, zinc, and hardness proceeded without incident. Quality control results, including a method blank showing no detected ethylene or propylene glycol above 5.0 mg/L, are included in the report.

A February 2002 laboratory report from Analytical Resources, Inc. documents the analysis of four water samples submitted by the law firm Smith & Lowney, P.L.L.C. for a project identified as Case 2. The samples were tested for metals, conventional parameters, and glycols, with results showing no ethylene or propylene glycol detected above the 5.0 mg/L detection limit. A calibration issue with the glycol analysis required re-testing outside the standard holding time, though re-analysis confirmed the original findings.

Analytical Resources, Inc. submitted water sample analysis results to attorney Richard Poulin of Smith & Lowney law firm in February 2002 for a matter identified as Case 1. Nine water samples were collected on January 28, 2002 and tested for ethylene glycol and propylene glycol, with neither compound detected above the 5.0 mg/L detection limit. The chain of custody record shows samples were collected by Greg Wingard of CASE and received by ARI laboratory staff for quality-controlled analysis.

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.

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.
