Update or Other Action |
Discussed draft CC letter with Tom Barrett, Kenai Peninsula Borough staff-person. He had no comments on the letter. He had searched the files at the school and found little useful information and no reports or data. Revised the CC letter and sent it to ADEC management for review & comment. The site could just as easily be fully closed with no adverse impacts to human health or the environment. |
