PUB2177

Petroleum-contaminated soil (PCS) is a solid waste in Missouri. Therefore, the disposal of PCS is restricted under the Missouri Solid Waste Management Law and regulations.  In lieu of disposal at a permitted solid waste facility, the Missouri Department of Natural Resources authorizes the beneficial use of PCS as fill material under the conditions listed below. The conditions are an integral part of the department’s authorization. The terms and conditions of this authorization are based on the requirements of the Missouri Solid Waste Management Law, the Missouri Clean Water Law, and the Missouri Hazardous Waste Law. This authorization pertains to the use of the specified materials pursuant to these statutes. For the purposes of this authorization, PCS includes only soil affected by virgin petroleum products. It does not include soil contaminated with used oil.

Conditions

The PCS supplier is responsible for providing the following information to any PCS end user prior to the removal of the PCS material from the site of origin:

The PCS end user is responsible for providing the following information to the PCS supplier prior to the removal of the PCS material from the site of origin:

The PCS supplier and the PCS end user shall maintain copies of the above information in their records, along with the results of any laboratory testing on the PCS material.  Although the information does not have to be submitted to the department for approval, the records must be available for review by department personnel upon request.

This authorization shall not be construed as compliance with any existing federal or state laws other than Missouri’s Solid Waste Management Law, Clean Water Law and Hazardous Waste Law, nor is this authorization be construed as a waiver of any other regulatory requirements. This authorization is not to be construed as compliance with any existing local permitting or zoning ordinances, nor does it supersede any local permitting and/or zoning requirements.

The department reserves the right to revoke, suspend or modify this authorization after due notice should the PCS supplier or PCS end user fail to comply with the terms and conditions of this authorization. The department expressly reserves the right to require appropriate corrective action if pollution, a public nuisance or a health hazard is created through the beneficial use of PCS.

Questions concerning this authorization should be directed to the department’s Solid Waste Management Program at 1-800-361-4827 or 573-526-3940 or in writing to P.O. Box 176, Jefferson City, MO 65102-0176. Thank you for your interest in protecting Missouri’s natural resources.

The directors of the department’s Hazardous Waste Program, Solid Waste Program and Water Protection Program approved this authorization.

Table 1 Beneficial Use Categories

Category

Petroleum

Contaminant Concentration

Allowable Uses

Nuisance Limitations

  •  Clean Fill

No detectable petroleum contamination

Unlimited Use

None

  •  Minimal Contamination

Below Missouri Risk-Based Corrective Action (MRBCA) default target levels for petroleum constituents*

PCS may be used as fill material without further approval of the department.  The PCS may not be placed in contact with groundwater or surface water and must be capped with at least one foot of clean fill material, or with at least two inches of asphalt or concrete

Although not a human health risk, the soil may exhibit odor, staining, oiliness or other characteristics that the end –user may find aesthetically objectionable (i.e., a nuisance).  Not recommended for fill around homes, gardens, play areas or other areas where there may be a high aesthetic consideration

  •  Moderate Contamination

Greater than MRBCA default target levels for petroleum constituents*

Beneficial use allowed with a written site-specific approval by the department’s Solid Waste Management Program.  This requires the submittal of a proposal addressing the regulatory requirements of 10 CSR 80-2.020(9)(B), as outlined in the Beneficial Use Guidelines. (see page 3).

See above.

Guidance to end users for the beneficial use of petroleum-contaminated soil
When managed properly, petroleum-contaminated soil (PCS) may be used in many construction applications as a direct replacement or substitute for other fill materials. This document is intended to outline for the end user the basic guidelines for the beneficial use of PCS. Note that the Missouri Department of Natural Resources authorizes the use of PCS only in accordance with the conditions stipulated in the technical bulletin Beneficial Use of Petroleum Contaminated Soil.

Beneficial use of PCS carries with it certain responsibilities. As the end user, you must use common sense and good management practices to ensure the material will not create an aesthetic problem. Don’t let your actions affect the quality of life of your friends and neighbors.

Good management practices include:

Following these simple guidelines should ensure that you do not create a nuisance.

There are other responsibilities associated with the beneficial use of PCS as well. As the end user, you must make sure these responsibilities are met. They include:

Notifying the landowner that PCS is being used and, if appropriate, marking property lines so that the material is not placed on someone else’s property;

* These responsibilities apply regardless of whether you are using PCS or some other material.
