On-Site Disposal Systems <br /> <br />Policy ~2 of ~C's "Water Resources Management Wastewater Treatment and <br />Handling Policy Plan" states: <br /> <br />On site sewage disposal systems are appropriate to serve <br />single family residences at deuelopment densities of four <br />units per 40 acres or less, if governments plan for them <br />and adopt a management and control system consistent with <br />federal and state laws and Metropolitan Council <br />Guidelines" <br /> <br />The policy statement does not reflect any consideration for the <br />intrinsic suitability of soils for septic systems (e.g. clay vs sandy <br />soils). <br /> <br />Figure 9 illustrates the typical septic system required for a typical <br />four bedroom house. The standard land area required for a primary on <br />site system and an alternate system is approximately 10,000 square <br />feet or 11% of a 2.5 acre lot. <br /> <br />CITY OF P~SEY ON-SITE SYSTEM MANAGEMENT PROGRAM <br /> <br />The city of Ramsey on-site sewage treatment regulations are addressed <br />in Ramsey City Code Chapter 150.1 (Sewage Disposal Systems), Ramsey <br />Zoning Ordinance Chapter 170.12 (Subdivision), and Chapter 170.13 <br />(Soils). The requ!ations are modeled in technical content after <br />~[innesota Rules 7080 (Individual Sewage Treatment Systems Standards). <br /> <br />Installation of a new or replacement septic system requires a permit <br />and inspection by the Ramsey Plumbing Inspector who is certified by <br />MPCA. The plumbing inspector maintains records of site evaluations <br />and designs of new septic systems where site evaluations are required. <br />Certain areas in Ramsey are known to have Class i soils; site evalua- <br />tions are not re~ired in these areas (see map of unsuitable areas). <br />However, mandatory site evaluation for new and replacement on-site <br />sewage treatment systems is under consideration by the City at this <br />time. The City Code re.~uires that the inspector or homeowners measure <br />scum level in septic tanks every two years. The City does inform <br />homeowners of the need for septic tank pumping maintenance by publica- <br />tion in local media once a year. The City inspects and cites failed <br />septic systems. However, septic system failures are usually reported <br />by homeowners or neighbors who live near the failed system. <br /> <br />The City requ~ires licenses for site evaluatcrs septic system <br />installers and pumpers. Si~e evaiuators must be certified by the MPCA <br />vo!unUary certification program. Beginning January !~$9, installers <br />must also be certified by the MPCA. <br /> <br />21 <br /> <br /> <br />
