Section 329IAC10-29-6. Phase I monitoring program

   (a) Phase I monitoring is required at all restricted waste sites Type I and Type II and nonmunicipal solid waste landfills except as otherwise provided in sections 7 and 9 of this rule.

  (b) A Phase I monitoring program for nonmunicipal solid waste landfills must include the following monitoring parameters:

(1) Field pH.

(2) Specific conductance.

(3) Chloride.

(4) Boron.

(5) Ammonia.

(6) Sodium.

(7) Chemical oxygen demand.

(8) Total phenolics.

(9) Methylene chloride.

(10) 1,1-dichloroethane.

(11) Toluene.

(12) Benzene.

(13) 1,2-dichloroethene, total.

(14) Ethyl benzene.

(15) 2-butanone, methyl ethyl ketone.

  (c) Appropriate monitoring parameters for restricted waste sites Type I and Type II must be determined by the commissioner based on the constituents of the waste permitted to be accepted at the site.

  (d) If the owner or operator of a restricted waste site Type I or Type II or nonmunicipal solid waste landfill determines, under section 5 of this rule, that there is a statistically significant increase over background for two (2) or more of the parameters under subsection (b) or (c) at any monitoring device at the monitoring boundary, the owner or operator shall do the following:

(1) Notify the commissioner within fourteen (14) days of this finding. The notification must indicate what Phase I parameters have shown statistically significant increases over background levels.

(2) Within sixty (60) days:

(A) sample the ground water in all monitoring devices;

(B) determine the concentration of all constituents identified in section 7(b) through 7(c) of this rule or section 7(d) of this rule; and

(C) report the results to the commissioner.

(3) Within a reasonable time period, to be established by the commissioner, establish a Phase II detection monitoring program meeting the requirements of section 7 of this rule.
