Importance: Normal

Sarah, I have reviewed the bio polishing workplan, dated November 3, 2009, and do not have any comments on the plan and therefore approve the plan for implementation. Please provide me with a final bound copy and one CD.

This email will be the only approval response so you may want to include a copy with your UIC application.
