TMDL Goals for Peltier and Centerville Lakes <br />Peltier and Centerville Lakes have been identified to be impaired. The nutrient causing <br />the impairment has been identified as phosphorus. The TMDL for Peltier/Centerville <br />Lake has identified a need to reduce the external phosphorus loading from Hardwood <br />Creek or Clearwater Creek by between 46 and 62 percent. Recent P8 modeling <br />completed by Houston Engineering provides significantly different existing phosphorus <br />load estimates than the information provided in the TMDL. Depending on the data <br />utilized, a 50% reduction would correspond to an annual reduction of phosphorus loading <br />from the City of Hugo of 500-1,500 pounds. <br />In order to achieve these goals it is anticipated the following actions could to be taken: <br />a) Reduce phosphorus loads from areas within in the City that develop or <br />redevelop by requiring the incorporation of BMPs consistent with <br />RCWD permitting standards. <br />b) Incorporate regional BMPs or retrofit existing BMPs to further reduce <br />the phosphorus loading from these areas. <br />CIP for Storm Water Projects Within the City of Hugo <br />City of Hugo, MN <br />WSB Project No. 1687-85 <br />Page 10 <br />
