Sec. 10. "Densic material" means relatively unaltered materials (do not meet requirements for any other named diagnostic horizons or any other diagnostic soil characteristic) that have a noncemented rupture resistance class. The bulk density or the organization is such that roots cannot enter, except in cracks. These are mostly earthy materials, such as till, volcanic mudflows, and some mechanically compacted materials. Some noncemented rock can be densic materials if they are dense or resistant enough to keep roots from entering, except in cracks. Densic materials are noncemented and thus differ from paralithic materials and the material below a lithic contact, both of which are cemented. Densic materials have, at their upper boundary, a densic contact if they have no cracks or if the spacing of cracks that roots can enter is ten (10) centimeters (cm) or more. These materials can be used to differentiate soil series if the materials are within the series control section.

(4) The tanks must either be:
(A) removed or the lids crushed into the tanks and the holes or tanks backfilled with debris-free sand or other granular material, concrete, or soil material that is compacted to prevent settling (if a sand mound is being abandoned, sand, aggregate and soil cover from the sand mound may be used for filling the tank or tanks); or
(B) filled with flowable fill.
(5) Properly grade and establish vegetative cover.

(b) The components of the soil absorption system may be left intact, if there are no plans to use the area for other purposes. Vegetative cover must be maintained.

(c) If effluent has surfaced, those areas must be covered with hydrated lime followed by top soil and a vegetative cover.

(d) If components of the soil absorption system are to be removed, the following procedure must be used:
(1) A licensed septic tank cleaner must pump all contents from all distribution boxes in the on-site sewage system.
(2) Allow sufficient time after the on-site sewage system is taken out of service and the tanks pumped to make sure the entire soil absorption system is completely dry.
(3) A contractor must remove the distribution network, aggregate, and sand (if any) from the site.
(4) The contractor must dispose of the materials at a licensed landfill.
(5) The site must be properly graded and a vegetative cover established.

(e) Written documentation of tank abandonment must be provided to the local health department by the homeowner in the form of a receipt from the contractor.
