Effective April 28, 2015 Chapter Four Subsurface Sewage Treatment System Regulations SECTION 22 MAINTENANCE 22.1 Management Plans Required. All new and replacement SSTS must be operated in accordance with the management plan submitted, reviewed and approved by the Department prior to issuance of a construction permit. At a minimum, management plans must include the following: (1) maintenance requirements, including frequency; (2) operational requirements, including which tasks the owner can perform and which tasks a licensed service provider or maintainer must perform; (3) monitoring requirements; (4) requirements that the owner notify the Department when the management plan requirements are not met; (5) disclosure of the location and condition of the additional soil treatment and dispersal area on the lot or serving that residency; and (6) other requirements determined by the Department. 22.2 General. SSTS and all components must be maintained in compliance with this Chapter and manufacturer requirements. 22.3 Frequency of Assessment. The owner of an SSTS or the owner's agent shall regularly, but in no case less frequently than every three years: (1) Assess whether sewage tanks leak below the designed operating depth and whether sewage tank tops, riser joints, and riser connections leak through visual evidence of major defects. (2) Measure or remove the accumulation of scum, grease, and other floating materials at the top of each septic tank and compartment, along with the sludge, which consists of solids denser than water. 22.4 Maintenance Permit and Reporting. Prior to performing the maintenance required in Section 22.3 (2) a maintenance permit must be obtained by the licensed maintenance business from the Department. A valid maintenance permit must be on the site where the maintenance activities are being performed. A completed pumping record must be provided to the Department within 90 days of the maintenance activity. 22.5 Removal of Material. (1) All solids and liquids must be removed by pumping from all tanks or compartments in which the top of the sludge layer is less than 12 inches from the bottom of the outlet baffle or transfer hole or whenever the bottom of the scum layer is less than three inches above the bottom of the outlet baffle or transfer hole. Total sludge and scum volume must not be greater than 25 percent of the tank's liquid capacity. (2) Removal of accumulated sludge, scum, and liquids from septic tanks and pump tanks must be through the maintenance hole. The removal of solids from any location other than the maintenance hole is not a compliant method of solids removal from a sewage tank, and this method does not fulfill the solids removal requirements of this Section or a management plan. Liquid and solids removal from cleanout pipes is allowed for holding tanks. (3) After removal of solids and liquids, from a system installed after the effective date of this Chapter, the maintenance hole cover must be secured as described in Section 13.18(1). Covers secured by screws shall be refastened in all screw openings. (4) After removal of solids and liquids from a system installed prior to the effective date of this Chapter maintenance hole covers must be sound, durable, and of adequate strength as specified in Section 13.18(3), and: (A) Be buried with a minimum of 12 inches of soil cover or, if the cover is currently at or above the ground surface or within 12 inches from final grade, be secured by a method that was deemed secure prior to the effective date of this Chapter. 80 Washington County Development Code
