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

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 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.

In February 1998, the U.S. EPA Region 10 wrote to the Army Corps of Engineers recommending denial of a permit for the Port of Seattle's proposed third parallel runway at Seattle-Tacoma International Airport, citing concerns over the filling of more than 11 acres of wetlands and portions of Miller Creek and Des Moines Creek. The EPA objected that the applicant's mitigation plan relied almost entirely on off-site wetland replacement in the Green River Valley rather than within the affected watersheds, and questioned whether alternatives to wetland fills for the South Aviation Support Area and on-site borrow areas had been adequately explored. The agency indicated it was willing to work with the Corps and the Port to identify solutions that would satisfy both aviation safety needs and Clean Water Act Section 404(b)(1) requirements.
