Utah Admin. Code R315-265-314 - Landfills - Special Requirements for Bulk and Containerized Liquids

(a) The placement of bulk or non-containerized liquid hazardous waste or hazardous waste containing free liquids, whether or not sorbents have been added, in any landfill is prohibited.

(b) Containers holding free liquids may not be placed in a landfill unless:

(1) the free-standing liquid;

(i) has been removed by decanting, or other methods;

(ii) has been mixed with sorbent or solidified so that free-standing liquid is no longer observed; or

(iii) had been otherwise eliminated; or

(2) the container is very small, such as an ampule; or

(3) the container is designed to hold free liquids for use other than storage, such as a battery or capacitor; or

(4) the container is a lab pack as defined in Section R315-265-316 and is disposed of in accordance with Section R315-265-316.

(c) To demonstrate the absence or presence of free liquids in either a containerized or a bulk waste, the following test shall be used: Method 9095B, Paint Filter Liquids Test, as described in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", EPA Publication SW-846, as incorporated by reference in Section R315-260-11.

(d) The date for compliance with Subsection R315-265-314(a) is November 19, 1981. The date for compliance with Subsection R315-265-314(c) is March 22, 1982.

(e) Sorbents used to treat free liquids to be disposed of in landfills shall be nonbiodegradable. Nonbiodegradable sorbents are: materials listed or described in Subsection R315-265-314(e)(1), materials that pass one of the tests in Subsection R315-265-314(e)(2); or materials that are determined by the director to be nonbiodegradable through the Rule R315-260 petition process.

(1) Nonbiodegradable sorbents include:

(i) inorganic minerals, other inorganic materials, and elemental carbon such as aluminosilicates, clays, smectites, Fuller's earth, bentonite, calcium bentonite, montmorillonite, calcined montmorillonite, kaolinite, micas such as illite, vermiculites, zeolites; calcium carbonate, organic free limestone, oxides or hydroxides, alumina, lime, silica, sand, diatomaceous earth, perlite, volcanic glass; expanded volcanic rock, volcanic ash, cement kiln dust, fly ash, rice hull ash, activated charcoal or activated carbon; or

(ii) high molecular weight synthetic polymers such as polyethylene, high density polyethylene (HDPE), polypropylene, polystyrene, polyurethane, polyacrylate, polynorborene, polyisobutylene, ground synthetic rubber, cross-linked allylstyrene and tertiary butyl copolymers. This does not include polymers derived from biological material or polymers specifically designed to be degradable; or

(iii) mixtures of these nonbiodegradable materials.

(2) Tests for nonbiodegradable sorbents.

(i) The sorbent material is determined to be nonbiodegradable under ASTM Method G21-70, 1984a,---Standard Practice for Determining Resistance of Synthetic Polymer Materials to Fungi; or

(ii) The sorbent material is determined to be nonbiodegradable under ASTM Method G22-76, 1984b,---Standard Practice for Determining Resistance of Plastics to Bacteria; or

(iii) The sorbent material is determined to be nonbiodegradable under OECD test 301B: (CO2 Evolution (Modified Sturm Test)).

(f) The placement of any liquid that is not a hazardous waste in a landfill is prohibited unless the owner or operator of the landfill demonstrates to the director, or the director determines that:

(1) the only reasonably available alternative to the placement in the landfill is placement in a landfill or unlined surface impoundment, whether or not permitted or operating under interim status, which contains, or may reasonably be anticipated to contain, hazardous waste; and

(2) placement in the owner or operator's landfill will not present a risk of contamination of any "underground source of drinking water", as that term is defined in Section R315-270-2.
