The Minnesota Pollution Control Agency (MPCA) has developed mandated outcomes of a <br />performance system. <br />Bodily contact with sewage is not allowed. <br />All disposal of sewage effluent must be below grade. <br />The system must conduct itself in a safe manner, free from physical injury and <br />harm. <br />All performance systems must conform to all applicable federal, state and local <br />requirements. The system’s must also conform to the manufacturer's requirements <br />Chapter 7080 requires there must be some separation during loading of sewage <br />effluent into a soil dispersal system. <br />All fecal organisms must be totally removed within twenty-five (25) feet from the <br />soil dispersal area during climatic and loading stress. <br />If a lot adjoins a lake, there must be a phosphorous concentration of 1 mg/1 or <br />less. <br />If a lot adjoins a lake, the LGU has the option of instituting a nitrogen standard. <br />Monitoring and Mitigation Plan <br />A performance system will be similar to other septic systems in Orono. To obtain a permit, a site <br />design will need to be submitted to the Cit> for review. The site evaluation must be conducted <br />by a state licensed Designer 1 or Designer 2. A monitoring and mitigation plan must also be <br />included with the site design. The monitoring plan must state the type and frequency of <br />monitoring and require routine flow measurement. There are three types of monitoring. One <br />way is to use a monitoring well. A second way is soil monitoring. A third possibility is to take <br />water samples from the pretreatmenl system and assess them for contaminants. These water <br />samples would be sent to a certified laboratory'. The best monitoring plan is to use a combination <br />of these methods. A mitigation plan must show w hat will be done if the performance system <br />fails to provide treatment and disposal. Mitigation is the most important of all the requirements. <br />If the performance system is not performing up to the required standards, a plan must be in place <br />that will detail what type of system is going to replace the non-compliant performance system. <br />Operating Permit <br />If after reviewing the site design the system seems to be proper and will function properly, the <br />City would approve the design and the homeowner would then obtain a operating permit from <br />the City. Once the homeowner has obtained the operating permit, the licensed septic system
