Comment Binder A compiled by Port of Seattle for Sea-Tac Airport (Seattle-Tacoma International Airport) third runway project, containing letters submitted to the U.S. Army Corps of Engineers during the initial comment period (December 19, 1997 to January 20, 1998) and comments from the joint Corps/Ecology public hearing held April 9, 1998. Includes a January 15,

A 1998 letter from Fisheries Consultants to the U.S. Army Corps of Engineers concludes that SeaTac Airport's proposed Third Runway will have an overall neutral effect on aquatic habitat and fish populations in Miller Creek. Minor benefits are expected from new storm flow detention facilities, which will reduce peak flood flows by 5–20%, and from a planned 100-foot-wide stream buffer created through residential buyouts along the creek. Adverse impacts are limited to the temporary disruption of a quarter-mile creek relocation and an approximate 8% reduction in late-summer low stream flows due to increased paved surfaces and wetland fill.

April 9, 1998 letter from Gary Oldenburg, USDA Animal and Plant Health Inspection Service (APHIS) Wildlife Services State Director for WA/AK/HI/Pacific Islands, to Jonathan Friedman, U.S. Army Corps of Engineers Seattle District, regarding wildlife hazards at Sea-Tac Airport. Argues that wetland mitigation measures at SeaTac Airport should be conducted off-site, citing FAA Advisory Circular 150/5200-33

A April 6, 1998 internal memorandum from Paul Tappel to Jim Kelley identifies minor technical inconsistencies and questions in the Sea-Tac Airport JARPA permit application, focusing on discrepancies in engineering drawings, stream buffer widths, channel elevation profiles, and hydraulic calculations for a proposed Miller Creek relocation. Tappel raises concerns that the plan overstates the environmental benefits of the reconstructed creek channel and contains contradictory goals regarding wildlife habitat and airport bird-strike safety. He notes these issues are not critical to the overall assessment but could cause confusion as the design moves forward.

A March 1998 fax exchange between the Port of Seattle and Herrera Environmental Consultants concerns the scope of work and cost estimates for Third Runway Water Quality Compliance Services. Carlos Herrera of Herrera Environmental sent documents to Port of Seattle contacts Barbara Hinkle and Kym Mattress, arguing that routine project water quality monitoring should be Herrera's responsibility, covering both compliance and BMP performance monitoring. Herrera noted he believed this approach would be most credible to the Washington Department of Ecology and neighboring airport communities, and requested review and discussion of the cost estimates to potentially reduce the budget.
