Rule 1200-01-07-.04, continued)

    • (x)

  • (3)

    Buffer Zone Standards for Siting Landfills

(a)

Class I Disposal Facilities must be located, designed, constructed, operated, and maintained such that the fill areas are, at a minimum:

1.

100 feet from all property lines;

2.

500 feet from all residences, unless the owner of the residential property agrees in writing to a shorter distance;

3.

500 feet from all wells determined to be downgradient and used as a source of drinking water by humans or livestock; and

4.

200 feet from the normal boundaries of springs, streams, lakes, (except that this standard shall not apply to any wet weather conveyance nor to bodies of water constructed and designed to be a part of the facility);

5.

A total site buffer with no constructed appurtenances within 50 feet of the property line.

  • (b)

    Class II Disposal Facilities must meet the same buffer zone standards for siting as Class I facilities (subparagraph (a) of this paragraph).

  • (c)

    Class III and Class IV Disposal Facilities must meet the same buffer zone standards for siting as Class I facilities (subparagraph (a) of this paragraph).

  • (4)

    Leachate Migration Control Standards

    • (a)

      Class I Disposal Facilities

      • 1.

        Such facilities must have a liner designed to function for the estimated life of the

site and the post-closure care period. It shall be designed, constructed, and installed to ensure that the concentration values listed in Appendix III of this rule will not be exceeded in the uppermost aquifer at the relevant point of compliance. The liner must be:

(i)

A composite liner consisting of two components; the upper component must consist of a minimum 30-mil flexible membrane liner (FML), and the lower component must consist of at least a two-foot layer of compacted soil with a hydraulic conductivity of no more than 1.0 x 10-7 cm/sec. FML components consisting of high density polyethylene (HDPE) shall be at least 60-mil thick. The FML component must be installed in direct and uniform contact with the compacted soil component;

(ii)

Constructed of materials that have appropriate chemical properties and sufficient strength and thickness to prevent failure due to pressure gradients, physical contact with the waste or leachate to which they are exposed, climatic conditions, the stress of installation, and the stress of daily operation;
