   ACT. The Environmental Protection Act (ILCS Ch. 415, Act 5, §§ 1 et seq.).
   AGENCY. The Illinois Environmental Protection Agency.
   BOARD. The Illinois Pollution Control Board.
   MAXIMUM SETBACK ZONE. The area around a community water supply well established under Section 14.3 of the Act and this chapter, and described in § 156.06.
   MINIMUM SETBACK ZONE. The area around a community water supply well established under Section 14.3 of the Act and this chapter, and described in § 156.06.
   POTENTIAL PRIMARY SOURCE. Any unit at a facility or site not currently subject to a removal or remedial action which:
      (1)   Is used for the treatment, storage, or disposal of any hazardous or special waste not generated at the site; or
      (2)   Is used for the disposal of municipal waste not generated at the site, other than landscape waste and construction and demolition debris; or
      (3)   Is used for the landing, land treating, surface impounding or piling of any hazardous waste that is generated on the site or at other sites owned, controlled or operated by the same person; or
      (4)   Stores or accumulates at any time more than 75,000 pounds above ground, or more than 7,500 pounds below ground, of any hazardous substances.

      (3)   A potential primary source which is part of a facility that undergoes major reconstruction. Such reconstruction shall be deemed to have taken place where the fixed capital cost of the new components constructed within a two-year period exceed 50% of the fixed capital cost of a comparable entirely new facility.
Construction shall be deemed commenced when all necessary federal, state, and local approvals have been obtained, and work at the site has been initiated and proceeds in a reasonably continuous manner to completion.
   POTENTIAL ROUTE. Abandoned and improperly plugged wells of all kinds, drainage wells, all injection wells, including closed loop heat pump wells, and any excavation for the discovery, development or production of stone, sand or gravel.
A new potential route is:
      (1)   A potential route which is not in existence or for which construction has not commenced at its location as of July 1, 1996, or
      (2)   A potential route which expands laterally beyond the currently permitted boundary or, if the potential route is not permitted, the boundary in existence as of July 1, 1996.

   POTENTIAL SECONDARY SOURCE. Any unit at a facility or a site not currently subject to a removal or remedial action, other than a potential primary source, which:
      (1)   Is used for the landfilling, land treating, or surface impounding of waste that is generated on the site or at other sites owned, controlled or operated by the same person, other livestock and landscape waste, and construction and demolition debris; or
      (2)   Stores or accumulates at any time more than 25,000 but not more than 76,000 pounds above ground, or more than 2,500 but not more than 7,500 pounds below ground, of any hazardous substances; or

      (3)   A potential secondary source which is part of a facility that undergoes major reconstruction. Such reconstruction shall be deemed to have taken place where the fixed capital cost of the new components constructed within a two-year period exceed 50% of the fixed capital cost of a comparable entirely new facility.
Construction shall be deemed commenced when all necessary federal, state, and local approvals have been obtained, and work at the site has been initiated and proceeds in a reasonably continuous manner to completion.
