TO: Ecology's SeaTac reviewers - Ray Hellwig, Gordon White, Kevin Fitzpatrick, Erik Stockdale, Dave Garland, Joan Marchioro FROM: Tom Luster RE: My most current list of issues to be resolved for SeaTac 401 review Here is my latest draft list of issues. They are in the following categories: General Issues Stormwater Management Plan Streamflows and Flow Augmentation Natural Resource Mitigation Plan/Wetlands Clean Fill Other Issues Future Probable Issues (if401 is issued) You'll note some overlap between the various areas. Also, I did not describe the various states of resolution of each issue. Some may just require some documents to be clarified or slightly modified, others may require significant new documentation or development of 401 condition language. And, of course, this list should be considered provisional pending future public comment and Ecology's evaluation of those comments.
