<br />. <br /> <br />2. Identify the presence, quantity, and type of 1/1 that <br />exists within the sanitary sewer. system. <br /> <br />3. <br /> <br />Evaluate each subsystem using U.S. <br />Protection Agency Program Requirements <br />78-10 cost-effectiveness criteria. <br /> <br />Environmental <br />Memorandum (PRM) <br /> <br />4. Determine current average and peak flow conditions from <br />the drainage subsystems and project these flows for future <br />conditions. <br /> <br />5. Evaluate each subsystem using cost-effectiveness criteria, <br />to determine whether sewer system evaluation survey <br />investigations are required. <br /> <br />6. <br /> <br />. <br /> <br />Prepare a report summarizing the investigations and <br />identifying the scope of additional sewer system <br />evaluation investigations in the subsystems found to have <br />1/1 sources which appear to be cost-effective to <br />eliminate. Present the results of the detailed <br />infiltration/inflow analysis study, Phase II, III and IV, <br />in a report to the Owner, the Commission, the MPCA and the <br />U.S. EPA. The report will provide necessary information <br />to document the nonexistence or possible existence of <br />excessive 1/1 in the Owner's sanitary sewer system, based <br /> <br />- 7 - <br />
