All vaults or other approved receptacles used by any person for storage of sewage shall be emptied completely at least once each year. Additionally, whenever the level of sewage in such vault or receptacle is allowed to reach eighty percent (80%) of capacity or a point twelve (12) or less inches below any removal or leakage point, or the ceiling of such vault or receptacle, whichever point is lower, a notice of violation will be issued to the owner or operator of the facility using such vault or receptacle, allowing seven (7) days for complete removal of such sewage. Upon any failure to comply with a notice to remove all sewage within seven (7) days, the house, cabin, human habitation or camping place, or other facility involved in such notice may be closed and sealed to prevent it use until the owner or operator of such facility complies herewith. If determined a health hazard by the Director, all owners and others having control over the use of such facilities are encouraged to keep the level of sewage below sixty percent (60%) of the vault’s capacity to allow sufficient reserve for emergencies.
