(A) The soil absorption field must be located in an area such that the proposed trench bottom is equal to or higher than the elevation of the 100-year flood plain as designated on the FIRM. The infiltrative surface (i.e., the ground surface) for elevated sand mounds must also be equal to or above the elevation of the 100-year flood plain as designated on the FIRM.
(B) After a proposed soil absorption field installation area has been selected and approved, the area in which it is to be installed shall not be cut, filled, compacted, excavated, altered or disturbed, unless the alterations performed are specified on the construction permit approved by the Health Officer.
(C) In the event that an approved absorption field area is cut, filled, compacted, excavated, altered or disturbed in a way which is not approved by the Health Officer, the construction permit shall be void. If the damage can be overcome or another area used, a new application for a construction permit can be submitted along with a new construction permit fee which will be required.
(D) The area proposed for the soil absorption field shall be protected from vehicular traffic by roping or fencing prior to construction permit issuance. Vehicular traffic in the proposed absorption field area is permitted only in connection with the installation of the absorption field under the supervision of a registered installer. If the proposed absorption field area is damaged, a new on-site evaluation will be required. If the soil characteristics have changed, the construction permit will be void. If the damage can be overcome or another area used, a new application for a permit can submitted along with a new construction permit fee which will be required.
(E) Property alterations or additions such as garages, driveways, patios, swimming pools and like structures or improvements shall not be placed on or over the soil absorption field area or in any future expansion or reserve area required under § 52.26.
(F) Discharges from foundation footing drains, air conditioners, dehumidifiers, downspouts and other clear water drains shall not be allowed into or onto the absorption field or in the area above the absorption field where such would drain across the absorption field. A subsurface discharge shall be utilized for such clear water discharges.
(G) Where it is necessary to pump sewage from an area below the residential sewer or the facility sewer, a separate leak-proof sump shall be provided exclusively for such purposes.
