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 City 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 pretreatment 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 what 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 <br /> installer would then secure the septic permit. This septic permit would not be available until the <br /> homeowner had obtained the operating permit. The operating permit would contain maintenance <br /> requirements informing the homeowner of what will be required from the homeowner over the <br /> life of the system. The operating permit will include approved monitoring and mitigation plans. <br /> It will also include a section stating what is going to be required for compliance and the <br />
