   DESIGN STANDARDS. A control which is implemented by a potential contamination source to prevent discharges to the ground water. Spill protection is an example of DESIGN STANDARD.
   LAND MANAGEMENT STRATEGIES. Zoning and non-zoning controls which include, but are not limited to, the following: zoning and subdivision ordinances, site plan reviews, design and operating standards, development rights, public education programs, ground water monitoring, household hazardous waste collection programs, water conservation programs, memoranda of understanding, written contracts and agreements and so forth.
   POLLUTION SOURCE.
      (1)   Point source discharges of contaminants to ground water or potential discharges of the liquid forms of “extremely hazardous substances” which are stored in containers in excess of “applicable threshold planning quantities” as specified in SARA Title III.
      (2)   Examples of possible POLLUTION SOURCES include, but are not limited to, the following: storage facilities that store the liquid forms of extremely hazardous substances, septic tanks, drain fields, Class V underground injection wells, landfills, open dumps, landfilling of sludge and septage, manure piles, salt piles, pit privies, and animal feeding operations with more than ten animal units.
      (3)   The following clarify the definition of POLLUTION SOURCES.
         (a)   ANIMAL FEEDING OPERATION. A lot or facility where the following conditions are met: animals have been or will be stabled or confined and fed or maintained for a total of 45 days or more in any 12-month period, and crops, vegetation forage growth or post-harvest residues are not sustained in the normal growing season over any portion of the lot or facility. Two or more ANIMAL FEEDING OPERATIONS under common ownership are considered to be single feeding operation if they adjoin each other, if they use a common area, or if they use a common system for the disposal of wastes.
         (b)   ANIMAL UNIT. A unit of measurement for any animal feeding operation calculated by adding the following numbers: the number of slaughter and feeder cattle multiplied by 1.0, plus the number of mature dairy cattle multiplied by 1.4, plus the number of swine weighing over 55 pounds multiplied by 0.4, plus the number of sheep multiplied by 0.1, plus the number of horses multiplied by 2.0.
         (c)   EXTREMELY HAZARDOUS SUBSTANCES. Those substances which are identified in the Section 302(EHS) column of the Title III List of Lists - Consolidated List of Chemicals Subject to Reporting Under SARA Title III, (EPA 560/4-91-011).

   REGULATORY AGENCY. Any governmental agency with jurisdiction over hazardous waste, as defined herein.
   SANITARY LANDFILL. A disposal site where solid wastes, including putrescible wastes, or hazardous wastes, are disposed of on land by placing earth cover thereon.
   SEPTIC TANK/DRAIN-FIELD SYSTEMS.
      (1)   A system which is comprised of a septic tank and a drain field which accepts domestic wastewater from buildings of facilities for subsurface treatment and disposal.
      (2)   By their design, SEPTIC TANK/DRAIN FIELD SYSTEM discharges cannot be controlled with design standards.
