WATER QUALITY W/12/79 should generally prohibit the installa- tion of standard on-site systems in: areas where problems are likely to occur because of soil constraints or other geologic or hydrologic characteristics; b. iow swampy areas or areas subject to recurrent flooding; areas where the highest known groundwater table, bedrock or impervious soil conditions are within three feet of the bottom of a system. On-site system ordinances shall contain application and review procedures and requirements for the issuance of on- site system permits. Such requirements should provide for the receipt of a permit to install an on-site system prior to, or in conjunction with, the issuance of a building permit. Applic~- tion and installation requirements should provide for the transmission of adequate system and site information and a review procedure to ensure compliance with the ordinance. 2.1 Ordinances shall require that applica- tions contain a description of the site's characteristics, including a soils and subsurface evaluation based on bor- ings, percolation tests, and a descrip- tion of the proposed system. 2.2 Subdivision (or other) ordinances should provide for the approval of plats only following a determination that the soils in the platted area gen- erally are suitable for the installation of on-site systems consistent with the on-site system ordinance requirements. 2.3 Separate site testing should be per- formed in connection with all on-site system applications. On-site system ordinances should contain installation, inspection and acceptance procedures that require all new installations, mod- ifications or repairs to be inspected 3.1 3.2 and approved prior to covering the system.

Where necessary and · consistent with Policy 44 ~)f the Coun- cil's Water Quality Management Plan and Paragraph 3.1, local government~ should require maintenance of a septic tank when inspection reveals that sludge reaches a point 12 inches below the bottom of the outlet baffle and/or the scum reaches a point three inches above the bottom of the outlet baffle. Maintenance requirements for alterna- tire systems should be established in the ordinance or at the time of installa- tion permit approval. Recordkeeping. All local programs should provide for'recordkeeping re- lating to the design and location of new and/or renovated on-site systems. System owners or their agents should be required to submit a final descrip- tion of the system as installed to the
