Scoping Comments, Pending Part 150 Study at Seattle-Tacoma International Airport

The Regional Commission on Airport Affairs submitted formal scoping comments in February 2010 criticizing the planned Part 150 noise study at Seattle-Tacoma International Airport as too narrow in scope and insufficient in public participation opportunities. The comments call for improvements in study documentation standards, including proper indexing, clear citations, author transparency, and plain-English presentation of data. The commission also urges that public comment periods be at least 60 days and not scheduled around major holidays.

Notes

Scoping comments submitted by the Regional Commission on Airport Affairs (RCAA) dated 20 February 2010 regarding the pending Part 150 noise study at Seattle-Tacoma International Airport, with Landrum & Brown serving as lead consultants under a 6 November 2009 services agreement with Port Of Seattle. RCAA argues the study scope is too narrow and community participation opportunities are inadequate under governing FAA regulations. Comments address editorial standards including topical indexing, document format (8.5×11, no fold-outs), citation adequacy, authorship transparency, accuracy, use of real numbers vs. percentages, and comment period timing.
