0 <br />Minnesota F ollution Control Agency <br />JUL ? s 1986 <br />Mr. Clifford Reep <br />16820 Edgewood Avenue <br />Wayzata, Minnesota 55391 <br />Dear Mr. Reep: <br />Re: Heat Pump Discharge Permit for Mr. William Ulrich <br />1535 Bohns Point Road, Orono <br />This letter is in answer to your phone inquiry regarding the need for a <br />permit to discharge water from a heat pump to waters of the state. The <br />Minnesota Pollution Control Agency (MPCA) is presently seeking authority to <br />administer a general permit program for heat pump and non -contact cooling <br />water dischargers from the U.S. Environmental Protection Agency. A general <br />permit is a generic permit that allows us to process dischargers of a <br />similar nature without issuing individual permits, thus saving processing <br />time. In order to meet heat pump general permit criteria the discharge must <br />be less than 100,000 gallons per day and not use water treatment additives <br />that we would regulate. <br />The MPCA is presently accepting permit applications for dischargers in this <br />category in the interim until final program approval is received. We <br />presently have several hundred applications for heat pumps and non -contact <br />cooling water discharges that fit into the general permit category. <br />We anticipate that there are many more heat pump dischargers that we need to <br />locate. <br />Enclosed are two copies of a Shortform C discharge application and one set <br />of instructions. Fill out both copies of the application, keeping one for <br />yourself and send the other to us. If you have any further questions, <br />please contact me at (612) 296-7238. <br />Sincerely, <br />Gary Kimball <br />Senior Biologist <br />Permits Section <br />Division cf Water Quality <br />GLK: jae <br />Enclosures <br />
