Current through October 15, 2024

Section 250-RICR-140-05-6.3 - Petroleum Contaminated Soil Processing Facility - Design Standards

A. Process Equipment

1. Process equipment shall be designed to include the best available air pollution control equipment to ensure the most complete destruction of vaporized hydrocarbons.

2. This may include after-burner equipment or other equally efficient methods.

B. Design of Storage Chamber for Incoming Contaminated Soil

1. An enclosed structure(s) and a permanent roof to keep out adverse weather elements shall be provided.

2. Soil shall rest on a permanent, impervious floor, sloped to channel any run-off petroleum products and water to a collection point or area.

3. Berming of the structure (including any opening in the building for vehicle access) shall be provided to prevent inflow of rainwater (run-on) and to prevent run-off of petroleum contaminant/water from the storage piles onto soil outside the enclosure.

4. Adequate venting, such as through use of roof vents, shall be provided to prevent build-up of petroleum vapors.

5. Natural lighting, rather than electric lighting or other types of artificial lighting, shall be provided.

6. Electric power sources or any other sources of heat or sparks shall be avoided. Electrical devices, if any, shall meet the appropriate fire codes governing prevention of sparks.

7. Soil storage, prior to completion of the fingerprinting process, includes the following options:

a. Storage in the enclosed structure(s) with provisions to allow for, at minimum, all loads from a given generator site to be segregated from loads from other sites until fingerprint sampling and testing has been completed and the loads have been accepted for processing.

b. Storage in trucks at the facility until the soil has been fingerprinted and has been accepted for processing. The trucks shall be covered until the soil is unloaded.

8. Sufficient storage capacity shall be provided for soils to be stored per § 6.3(B)(7)(a) of this Part, as well as for soils that have been accepted and are awaiting transfer to the kiln for processing.

C. Design of Holding Area for Processed Soil at Process Facility Site

1. Processed soil that has a total petroleum hydrocarbon (TPH) concentration of less than 300 ppm may be stored at the process facility site without any containing enclosure or holding pad.

2. Processed soil that has a total petroleum hydrocarbon (TPH) concentration of 300 ppm or greater must be stored on an impervious holding pad, and adequately bermed to prevent run-off from the pile from escaping to the surrounding soil.

3. Adequate erosion and sedimentation control to minimize effect of any runoff from the stored processed piles should be included.
