"Lawn Area" is the area bounded by the dimensions required for the proper location of the soil treament area. 22. '~ottling" is a zone of chemical oxidation and reduction activity appearing as spoltchy patches of red, brown, orange, and gray. 23. "Mound System" is a system where the soil treatment area is built above the ground to overcome limits imposed by proximity to water table or bedrock, or by rapidly or slowly permeable soils. 24. "Percolation Rate" is the time rate of drop of a water surface in a test hole as specified in Section 150.014F of this chapter. 25. "Plastic Limit" is soil moisture content below which the soil may be manipulated for purposes of installing a soil treament system and above which manipulation will cause compaction and pudd~ling. If a fragment of soil can easily be rolled into a wire one-eighth (1/8) inch in diameter, the moisture content is above the plastic limit. If the soil is dry enough to be friable and falls apart when rolling it into a wire, the moisture content is below the limit and the soil may be manipulated. The standard method of determining the plastic limit is specified in American Association of State Highway Officials (AASHO) Designation: #T 90-61. 26. "Sand" is a soil texture composed by weight of at least twenty- five per cent (25%) of very coarse, coarse, and medium sand varying in size from two (2) to 0.25 mm, less than fifty per cent (50%) of fine or very fine sand ranging in size between 1.25 and 1.05 mm, and no more than ten per cent (10%) of particles smaller than 0.05 mm. 27. "Seepage Pit" (or leaching pit or dry well) is an underground pit into which a sewage tank discharges sewage or other liquid waste and from which the liquid seeps into the surrounding soil through the bottom and openings in the side of the pit. 28. "Setback" is a separation distance measured horizontally. 29. "Sewage" is any water-carried domestic, commercial, or agricultural waste, exclusive of footing and roof drainage or any residence, or any industry, agricultural, or commercial establishment or other structure, whether treated or untreated, and includes but is not limited to liquid waste produced by bathing, laundry, culinary operations and liquid wastes from toilets and floor drains. 30. "Sewage Tank" is a watertight tank used in the treatment of sewage and includes, but is not limited to, septic tanks and aerobic tanks. 31.
