a) For a unit subject to Subpart E (land treatment units) or Subpart F (surface impoundments), sampling shall be at least quarterly and analysis shall be for pH, specific conductance, total organic carbon, total organic halogen, and any other parameter that meets the following criteria:
1) Material containing such parameter is stored, treated or disposed of at the unit; and
2) The Board has adopted a groundwater standard for such parameter.
b) For a unit subject to Subpart I for the storage and handling of pesticides, sampling shall be at least quarterly, except as provided in subsection (d), and analysis shall be for five specific pesticides or five groups of chemically-similar pesticides stored or handled at the unit that are the most likely to enter into the groundwater from the unit and that are the most toxic. The owner or operator shall choose the five specific pesticides or five groups based upon the following criteria:
1) The volume of the pesticides stored or handled at the unit;
2) The leachability characteristics of the pesticides stored or handled at the unit;
3) The toxicity characteristics of the pesticides stored or handled at the unit;
4) The history of spillage of the pesticides stored or handled at the unit; and
5) Any groundwater standards for the pesticides stored or handled at the unit.
c) For a unit subject to Subpart J for the storage and handling of fertilizer, sampling shall be at least quarterly, except as provided in subsection (d), and analysis shall be for pH, total organic carbon, nitrates as nitrogen, ammonia nitrogen, and specific conductance.
d) Subsections (b) and (c) notwithstanding, for a unit subject to Subpart I for the storage and handling of pesticides or for a unit subject to Subpart J for the storage and handling of fertilizers, sampling shall be at least semi-annually provided that all of the following conditions are met:
1) The unit is in compliance with the containment requirements of 8 Ill. Adm. Code 255;
2) There have been no detections within the preceding two years in any of the monitoring wells of any contaminant stored or handled at the facility or of any contaminant attributable to operation of the unit; and
e) For a unit subject to Subpart K for the storage and handling of road oils or subject to Subpart L for the storage and handling of de-icing agents, sampling shall be annually and analysis shall be for pH, specific conductance, total organic carbon and total organic halogen.
