Sec. 7.

(a) This section applies to:

(1) permit applications under this article for new MSWLFs and lateral expansions; or

(2) MSWLFs permitted under 329 IAC 1.5, which was repealed in 1989, or 329 IAC 2, which was repealed in 1996.

(b) Applicants for new MSWLFs and lateral expansions that are applying for a permit under this article and for new MSWLFs and lateral expansions permitted under 329 IAC 1.5, which was repealed in 1989, or 329 IAC 2, which was repealed in 1996, must construct any MSWLF unit within the new MSWLFs or lateral expansions on a stable foundation. As used in this subsection, "stable foundation" means the following:

(1) The loads and loading rate of the foundation must not cause or contribute to the failure of the leachate collection system.

(2) The total and differential settlement of the foundation must not cause or contribute to the failure of the leachate collection system.

(3) The new MSWLF unit must be designed to achieve a factor of safety against bearing capacity failure of at least two (2.0) under static conditions and of at least one and five-tenths (1.5) under seismic conditions.

(4) The new MSWLF unit must be designed to achieve a factor of safety against slope failure in accordance with Table 1 in 329 IAC 10-15-8.

(5) Factors of safety must be calculated for both long term and short term conditions expected at the site.

(6) Earthquake induced liquefaction potential or blasting in the unstable area and the effect on the bearing capacity and integrity of the new MSWLF unit must be considered in the design.

(7) Other factors of safety that may be approved by the commissioner.

(c) Permittees of MSWLFs permitted and constructed under 329 IAC 1.5, which was repealed in 1989, or 329 IAC 2, which was repealed in 1996, must demonstrate to the commissioner that engineering measures have been incorporated into the design of any MSWLF unit located within the MSWLF to accommodate subsidence and to ensure that the integrity of the structural components of the MSWLF unit will not be disrupted.

(d) For all demonstrations, the commissioner may ask for additional information prior to approval or denial of the demonstration.
