Authority: IC 13-14-8-7; IC 13-15-2-1; IC 13-19-3-1

Affected: IC 13-30-2; IC 36-9-30

Sec. 3.

On and after the effective date of this article, the increased height beyond that which has previously been approved for existing nonmunicipal solid waste landfills must meet the following requirements:

(1) Be separated from any locally useful aquifer by material that:
(A) has an equivalent hydraulic conductivity through the barrier of less than or equal to 1 × 10-6 centimeters per second; and
(B) provides a cation exchange capacity (CEC) of at least two thousand three hundred (2,300) milliequivalents per square foot for recompacted soil or two thousand eight hundred (2,800) milliequivalents for natural soil for every vertical foot of solid waste in the site.
(2) For aquifers that are not locally useful beneath a site, the required CEC may be decreased by one-half (1/2) from that specified in subdivision (1).
(3) To the extent that a leachate collection system is designed and will be operated to remove a fraction of the leachate from a site, the barrier thickness calculated under subdivision (1) or (2) may be reduced in proportion to that fraction, except as provided in subdivision (5).
(4) In cases where an aquifer will exist horizontally adjacent to waste deposition, the required barrier thickness may be decreased from that specified in subdivisions (1) through (2) or subdivision (3) depending upon the projected leachate migration through the barrier.
(5) Notwithstanding any of the calculations in subdivisions (1) through (3) or subdivision (4), a minimum subsurface barrier adjacent to the waste or leachate collection system must be soil with an equivalent hydraulic conductivity through the barrier of less than or equal to 1 × 10-6 centimeters per second and a thickness of ten (10) feet over locally useful aquifers and five (5) feet in all other cases.
