Info

Monitoring of point source discharges is performed by permit holders, and in isolated areas, sporadically by the MDEQ. There is no comprehensive ongoing surface water quality monitoring program. Without systematic and strategic water monitoring a complete assessment is not possible. Next Steps: Successful programs like the NPDES permitting program should continue to be implemented and enforced; however, given the difficulty of monitoring and implementing TMDLs an effort should be made to regulate new discharges and hold new use allocations to a more stringent set of criteria than currently used. 58
Challenge # 16 Community Wastewater Systems Community wastewater systems (CWWS) are any system that treats and disposes of sewage and is privately owned. Typically, CWWS are proposed to allow greater density, create open space, provide for more economical means of treatment, or overcome site conditions. These systems can be small in terms of number of users to large servicing thousands of users. Smaller systems – less than 70 homes, are typically proposed as a large septic system. Larger ones are similar to municipal sewage treatment plants and often discharge to surface water via NPDES permit. Once built, ownership most frequently is turned over to a homeowner association representing the users who are responsible for the operation and maintenance. Challenges to groundwater can come from poor site selection, poor design, poor construction, and lack of monitoring and maintenance. Each element can contribute to improperly treated sewage contaminating groundwater and surface water. Community Wastewater Systems Response Objective: Assure CWWS are properly located, designed, and maintained to prevent groundwater and surface water contamination. What protection activities address the challenge of community wastewater systems? Clean Water Act Water Monitoring 59 Community Wastewater Systems Response Assessment: CWWS have not proliferated in the past due to a prerequisite by MDEQ that the local unit of government pass a resolution accepting liability in the event of failure. Recent Court decisions and State regulation has removed that requirement and the number of proposals has escalated. In an attempt to address the issue, Washtenaw County government and several Washtenaw County townships have enacted ordinances and regulations to address these critical points. Next Steps: Regulations that assure CWWS are properly located and operated should be enacted and enforced. Educational efforts to assure individual users are aware of the type of systems they are connected to and the dos and don’ts of how their actions can impact the system operation should be provided. Monitoring to assure systems are meeting design parameters must be a part of any CWWS. State legislation requiring prior zoning approval should be enacted.
