Are there any special Laws that regulate septic systems? (From www.septic-info.
Yes! In years past, septic systems were subject to very little regulatory oversight. Then in 1972, with the passage of what became known as the Clean Water Act, improperly treated wastewater from failing septic systems was identified as a key type of nonpoint (diffuse) pollution. Between then and now, the EPA has worked to develop guidelines for onsite wastewater treatment (septic system) management, and state governments and local authorities have been charged with implementing programs and regulations appropriate to their areas. Today, septic system regulations vary significantly on a state-by-state basis, and among towns and counties within states. This is because the federal government (through the EPA) does not mandate specific measures states and local authorities must adopt, but rather sets acceptable pollutant levels and pollutant reduction goals, and lays out voluntary guidelines for reaching these through better management on a state and local level.
