001 Whenever the use of an onsite wastewater treatment system is discontinued following the connection to a sanitary sewer or following condemnation or demolition of a building or property or due to the construction of another onsite wastewater treatment system, the onsite wastewater treatment system shall be properly closed and any further use of the system for any purpose shall be prohibited.
002 One of the following two methods shall be used for closure of a septic tank or holding tank:
002.01 Pump and Fill Method: The tank shall be pumped of all liquids and solids and then filled with soil. The soil shall be tamped completely so as to prevent voids which would occur as the result of settling; or
002.02 Pump and Remove Method: The tank shall be removed after being pumped of all liquids and solids and the void left from the tank removal shall be filled in with soil. The soil shall be mounded to provide for future settling.
003 The following method shall be used for closure of a wastewater lagoon:
003.01 The lagoon shall be drained or allowed to evaporate until there is no liquid remaining;
003.02 The fence shall be removed and the settled solids and liner material at the bottom of the lagoon shall be scraped out and properly disposed; and
003.03 The lagoon area shall be leveled and filled with clean soil. The soil shall be mounded over the lagoon area to provide for future settling and to prevent water from ponding.
