    (AA) Iodomethane.

    (BB) Methylene chloride.

    (CC) 4-methyl-2-pentanone.

    (DD) Styrene.

    (EE) 1,1,2,2-tetrachloroethane.

    (FF) Toluene.

      (b) The concentrations of the constituents listed in subsection (a) must not exceed current background concentrations or the maximum contamination level (MCL) established for the constituent, whichever is the higher concentration. If an MCL has not been established, then the concentration limit is the background concentration of ground water at the facility. When background is the standard, statistically significant exceedances must be determined as provided in section 5 of this rule.

      (c) As used in this section, "maximum contamination level" or "MCL" is defined under 329 IAC 10-2-110.
