Mr. David R. Hartley <br />City of Ramsey <br />Page 2 <br /> <br />The ground water pump out and treatment system is required to be <br />constructed and in operation by July, 1991. The City of Ramsey's <br />approval to discharge to the storm sewer is needed before final <br />plans can be completed by WMMI. It is anticipated that the ground <br />water pump out and treatment system will operate at its maximum <br />design flow of 1,100 gallons per minute (gpm) for the first ten <br />years of operation. After ten years the system will operate at a <br />flow rate of 600 gpm until acceptable cleanup levels have been <br />obtained, as determined by the MPCA. <br /> <br />On November 13, 1990, representatives of WMMI meet with the MPCA <br />to discus the Status of the NPDES permit application. During this <br />meeting, the following points were made regarding the discharge to <br />the City's storm sewer. <br /> <br />The monitoring location or point of compliance for WMMI's <br />NPDES permit will be at the outlet of the treatment unit and <br />not at the discharge point to the Mississippi River. <br /> <br />The City of Ramsey will not be a co-permittee to WMMI's NPDES <br />permit. <br /> <br />The City of Ramsey will not have any obligation to perform any <br />additional monitoring or reporting as a result of WMMI's NPDES <br />permit. <br /> <br />In the event City of Ramsey would have to obtain a storm water <br />discharge permit under the Federal Storm Water Regulations, <br />WMMI's discharge to the City of Ramsey's storm sewer will not <br />create additional monitoring or reporting under the Storm <br />Water Permit. <br /> <br />With the safety features built into the design, and assurances from <br />the MPCA that WMMI's discharge will not result in any additional <br />monitoring requirements for the City of Ramsey, it is felt that <br />discharging the treated ground water to the City's storm sewer will <br />not have any economic or environmental impact on the City. <br />Therefore, WMMI request that the City of Ramsey grant its approval <br />to discharge treated ground water to the City's storm sewer. <br /> <br />If you have any questions regarding this request, please feel free <br />to call me at 421-0540. <br /> <br />Sincerely, <br /> <br />Bruce Weaver, P.E. <br /> <br />cc: <br /> <br />Mr. Don Otter <br />Mr Steve Kollodge <br /> <br /> <br />
