   A substance listed above may be exempted from regulation under this chapter if the Regulated Substance does not present a threat to groundwater due to the nature of the substance, and the Facility Operator claiming this exemption for a specific Regulated Substance shows the Director of Public Utilities or Designee proper documentation from the chemical manufacturer or other qualified, verifiable source that the Regulated Substance does not present a threat to groundwater.

   (b)   Baseline Quantity Thresholds. Substances listed in Section 940.24(a) shall be considered regulated when, at any time of the year, the concentration of Regulated Substances stored or used at a facility meets or exceeds the lesser of the following quantities:

      (1)   When located within the one (1) and five (5) year TOT, in amounts exceeding fifty-five (55) gallons aggregate for liquid materials or four hundred forty (440) pounds aggregate for dry weights;

      (2)   When located within the ten (10) year TOT, in amounts meeting or exceeding one thousand (1,000) gallons aggregate for liquid materials or eight thousand (8,000) pounds aggregate for dry weights when stored aboveground, or five hundred (500) gallons aggregate for liquid materials when stored in an underground storage tank.

   (c)   Regulated Substances for Consumer Purchase. Storage of Regulated Substances packaged as consumer products in original containers for consumer purchase shall be regulated under this chapter only when storage meets or exceeds five hundred (500) gallons aggregate for liquid materials or four thousand (4.000) pounds aggregate for dry weights, whichever is less, in the one (1) and five (5) year TOT, or one thousand (1,000) gallons aggregate for liquid materials or eight thousand (8,000) pounds aggregate for dry weights, whichever is less, in the ten (10) year TOT.
