LRRWMO Meeting Minutes February 21, 1990 Page 3 CONSIDERATION OF COMMUNICATIONS Skallman presented DNR permit applications for review: Permit extension #88 -6079 -The DNR extended this permit for Don Watson, 17611 Round Lake Blvd. N.W., Andover, for a road stabilization and wildlife enhancement project. Permit application #90 -6183 - Robert Dehn, Dehn's Gardens, 16485 Tulip St. N.W., Anoka, requests a permit to appropriate 20 inches of water at 80 g.p.m. to irrigate 16 acres of vegetables. Skallman reported the well is already in. No recommendation was made for the commission's consideration in that they haven't concerned themselves with ground water to date. The DNR is currently monitoring ground water. Motion was made by Raatikka, seconded by Weaver, to CONVEY TO THE DNR THAT THE LRRWMO HAS NO COMMENT ON THIS PERMIT APPLI- CATION AS LONG AS GROUND WATER SUPPLIES ARE ADEQUATE FOR IRRIGATION PURPOSES. 4 ayes - 0 nayes. Motion carried Permit application #90 -6161 - Skallman reported that Astra Products, Jeffrey Boeck, is requesting an after - the -fact Permit for two storm sewer outlets from Mineral Pond 3rd Addition, into Mineral Pond. Upon full review of the permit, Skallman stated the stability of the 18 -inch outlet is questionable. It was noted it is a residential redevelopment with several more acres yet to be developed as well as Mineral Pond being protected wetland #2 -119W. Skallman added that while the project might work, there are insufficient details on the permit application to be certain. He recom- mended that Astra Products install an energy dissipater. Raatikka indicated the draft Water quality Management Guidelines indicate this board will be allowing up to 8 feet per second if there is rip rap and an energy dissipater. Weaver stated he would discuss this project with Anoka's Public Works Director immediately following this meeting. Motion was made by Raatikka, seconded by Weaver, to MAKE THE FOLLOWING COMMENTS TO THE DNR RELATIVE TO PERMIT #90 -6161: THE STABILITY OF THE 18 INCH RCP IS QUESTIONABLE. THE OUTLET VELOCITY IS CALCULATED TO BE 11 FEET PER SECOND. THE GUIDE- LINES FOR WATER QUALITY NOW BEING DEVELOPED WOULD REQUIRE AN ENERGY DISSIPATER FOR VELOCITIES GREATER THAN 8 FEET PER SECOND. 4 ayes - 0 nayes. Motion carried. The Commission received a February 13, 1990, status report of the 11 509" plan review from Bruce Sandstrom, Board of Water and Soil Resources.
