Effective April 28, 2015 Chapter Four Subsurface Sewage Treatment System Regulations includes household cleaners, medications, and other constituents in sewage restricted to amounts normally used for domestic purposes. Domestic waste has a biochemical oxygen demand of 170 mg/L or less (or carbonaceous biochemical oxygen demand of 125 mg/L or less), a total suspended solids level of 60 mg/L or less, an oil and grease concentration of 25 mg/L or less and no hazardous wastes. Animal waste and commercial or industrial waste are not considered domestic strength waste. (33) Drip dispersal system. "Drip dispersal system" means a small diameter pressurized wastewater distribution system in which the treated effluent is distributed under pressure to the infiltrative surface via drip tubing and enters the receiving environment. (34) Drop bog. "Drop box" means a distribution device used for the serial gravity application of sewage tank effluent to a soil dispersal system. (35) Dwelling. "Dwelling" means any building with provision for living, sanitary, and sleeping facilities. (36) Effluent screen. "Effluent screen" means a device installed on the outlet piping of a septic tank for the purpose of retaining solids of a specific size. (37) EPA. "EPA" means the United States Environmental Protection Agency. (38) Existing system. "Existing system" means a system that has been previously inspected and approved by the Department or local unit of government during installation. In addition, all operating systems installed before the adoption of this Chapter are considered existing systems. (39) Faint. "Faint" means a soil color in the Munsell Soil -Color Charts: (A) with the same hue as another soil color but that varies from the other color by two or less units of value and not more than one unit of chroma; (B) that differs from another soil color by one hue and by one or less units of value and not more than one unit of chroma; or (C) that differs from another soil color by two units of hue with the same value or chroma. (40) Fecal coliform or FC. "Fecal coliform" or "FC", for the purposes of this Chapter, means bacteria common to the digestive systems of humans that are cultured in standard tests. Counts of these organisms are typically used to indicate potential contamination from sewage or to describe a level of disinfection, generally expressed in colonies per 100 mL. (41) Fine Sand. "Fine sand" means a soil texture, as described in the Field Book for Describing and Sampling Soils, which is incorporated by reference in Section 2.2 (46) where more than 50 percent of the sand has a particle size range of 0.05 millimeters which is a sieve size of 270, to 0.25 millimeters which is a sieve size 60. (42) Flood fringe. "Flood fringe" means that portion of the floodplain outside of the floodway. Flood fringe is synonymous with the term "floodway fringe" used in flood insurance studies. (43) Floodplain. "Floodplain" means the area covered by a 100-year flood event along lakes, rivers, and streams as published in technical studies by local, state, and federal agencies, or in the absence of these studies, the estimates of the 100-year flood boundaries and elevations as developed by Washington County. (44) Floodway. "Floodway" means the bed of a wetland or lake, the channel of a watercourse, and those portions of the adjoining floodplain that are reasonably required to carry the regional flood discharge. (45) Flow measurement. "Flow measurement" means any method used to accurately measure water or sewage flow, including, but not limited to, water meters, event counters, running time clocks, or electronically controlled dosing. (46) Geomorphic description. "Geomorphic description" means the identification of the landscape, landform, and surface morphometry of the proposed area of the soil treatment and dispersal system as described in the Field Book for Describing and Sampling Soils: Version 2.0 (2002), developed by the National Soil Survey Center and Natural Resources Conservation Service of the United States Department of Agriculture. The field book is incorporated by reference into this ordinance. 12 Washington County Development Code
