zoning File #1340 September 27, 1988 Page 3 of 5 The second phase of the current conditional use permit application involves the placement of 1" thick contaminated soils excavated once again close to a doorway where possibly workers had dumped chemicals onto the soil. It was located within the area of the new addition. It is interesting to note that the preliminary investigations did not find this contaiminated area, but with the pattern of past disposal, the company suspected that they would find contaminated soils when the addition was excavated. Mr. Pallansch has advised that the sophisticated equipment used to detect these substances will be brought to your meeting so that you may be able to observe and question the engineers who will also be present at the meeting. The approximate 100 cubic yards are stored to the south of the parking lot with black plastic coverage and large pieces of sheeting to keep it self contained. Materials to be excavated from the trench which will also be contaminated with the same organic solvent and will be spread out over an area of the property to a 1" dep�, and then turned over and respread. I halve been advised by Mr. Pallansch that it will take approximately 2 to 3 months to rid the soils of the solvent. The process of evaporation will remove the contaminate. In Cook's letter, he recommends that small earth dikes may be desirable if there is a failure in the system. Such failure would result in contaminates going directly into Long Lake. Staff will include this in the Planning Commission recommendations. Members should question why the City has never been informed of the problems dating back to May of 1987. As Mr. Pallansch's letter dated 12/29/87 (Exhibit L) notes, WSI deals directly with the P.C.A. with all environmental issues and is subject to a monitoring program as part of a comprehensive environmental protection program. The P.C.A. is always the first agency to be advised of any problem. It is the company's responsibility to provide the necessary data and remedial action for the P.C.A.'s review, comment and approval. Staff has not had the opportunity to contact an agent from the P.C.A. but prior to the meetingstaff plans to discuss this application with the agents of the P.C.A. The curpose of my call would be to ask if it was not part of the normal process of the P.C.A. permit review to contact the local jurisdiction when there is proof presented that a property has been found to contain hazardous ma aerials. The conditional use permit with the City is merely based on the fact that there will be excavations in excess of 100 cubic yards of fill. Cook's letter even notes the time lag in notifying the City.
