Friday, July 15, 2005 . PCA review of Developers Voluntary Investigation and Clean Up Phase 2 Work Plan - approved July 5, 2005 (see attached documents). From on site re- ports tIus week, the consultant (AET) is nearly complete with their on-site bor- ing work. They have been communicating the types of materials as found and at what depths to the PCA for further consultation. It appears there is a hard pan layer of material at approximately 45 feet which can be a barrier to deeper penetration of contaminates, but further tests will be done. AET began their soil testing on June 23rd and also the testing ofthe ground water contamination. They have asked for access to the city's exploration wells in the area where the TCE was detected. Staff has given pennission to test out of those wells. They will also be test- ing to the north, south, east and west of these wells to try to identify a source. Chuck Bisek with AET will provided results from the tests as they come back. . Development Moratorium ends - August 1, 2005 . Rice Creek Watershed District permit approvals - Fall 2005, Early 2006 .

Lv-/) ncJYiJEm ber Ih Jan J M.erfJ D : Attached is Judy Helgen' s recent article from the Star Tribune ("Twin Lakes Pollution Problems Slipping By"). It raises a number of questions about the status of previous and current environmental clean-up needs in the Twin Lakes area. It also raises policy issues about how the city oversees environmental clean-up, and wbat the city requires from re- developers to ensure that needed clean-up actually occurs. Staff's response: The article misconstrued much of the information collccted by Ms. Helgen (for a "class research project" - not a jonrnalistic article) from the City and the PCA. The bottom line is the City is not the governmental agency that has juris- diction and expertise to enforce cnrrent state and federal environmental clean up standards. That is the job of the PCA. The same staff at the PCA are working on this project with the developers as were involved in 1994 when the first redevelop- ment of Twin Lakes occnrred under the Voluntary Investigation Cleannp program (VIC) and/or the Volnntary Petroleum Investigation Cleanup program (VPIC). The City currently has and always has had a great working relationship with the PCA. City staff has the confidence in their professional expertise to ensnre that the existing laws regarding clean up are enforced to the highest standard under the gnidance of the VIC and VPIC processes. 5
