Universal Citation: 20 NM Admin Code 20.9.8.15

Current through Register Vol. 35, No. 18, September 24, 2024

A. The generator of petroleum contaminated soil shall assure that all petroleum contaminated soils to be disposed, processed, composted, or transformed at a solid waste facility shall be tested under the requirements of 20.9.8.11 NMAC.

(1) All soils that are suspected to be contaminated with petroleum products shall be tested for total petroleum hydrocarbons (TPH) and other contaminants as required by the disposal management plan to determine the contaminants of the soil.

(2) The frequency of sampling shall be one representative sample per 100 cubic yards of contaminated soil, unless an alternate frequency is permitted or specifically approved by the secretary upon a demonstration that the contaminated soil is homogeneous.

(3) Copies of the results from the laboratory analyses shall be placed in the operating record.

B. Petroleum contaminated soils containing free liquid shall not be accepted at a solid waste facility. When the soil can pass the paint filter liquids test, the test results shall be placed in the daily operating record and made available to the secretary upon request.

C. Petroleum contaminated soil may be stored temporarily or remediated at a solid waste facility in a bermed area on an impermeable liner or in a manner that does not contaminate ground water, surface water, or uncontaminated soil above regulatory limits. The method of storage, remediation, and testing shall be described in the disposal management plan. Remediation shall be complete when the following conditions are met in a soil sample:

(1) the sum of benzene, toluene, ethylbenzene, and xylene isomer concentrations is less than 500 mg/Kg, with benzene individually less than 10 mg/Kg; and

(2) the TPH concentration is less than 1,000 mg/Kg.

D. Remediated petroleum contaminated soil may be disposed at a landfill authorized to accept petroleum contaminated soils. Petroleum contaminated soils that have been remediated at the landfill may be removed only if the soil complies with applicable environmental laws. Remediated petroleum contaminated soil may not be removed from the facility for beneficial use as clean fill, as the soil does not constitute clean fill as defined in Paragraph (4) of Subsection C of 20.9.2.7 NMAC.

E. Uncontaminated or remediated soils shall not be mixed with contaminated soils.

F. The owner or operator shall provide a written report to the department documenting remediation.

G. Permitted facilities not otherwise authorized to accept petroleum contaminated soil for remediation may remediate petroleum contaminated soil generated at the facility, provided the volume of contaminated soil does not exceed 50 cubic yards and the area where the petroleum contaminated soil is remediated is restricted from public access. Remediation shall be complete when the soil meets the standards in 20.5.12.1202 NMAC or other applicable standards.
