Section 250-RICR-140-05-6.2 - Petroleum Contaminated Soil Processing Facility - Operating StandardsA. Field Sampling to Provide Analytical Data for Evaluation of Candidate Soil The contaminated soil must be sampled and tested to adequately characterize it and to minimize the potential of accepting hazardous materials or materials that the soil processor is not permitted to accept. Details of field sampling and test strategies are provided in § 6.5 of this Part.
B. Laboratory Tests of Field Site Samples Samples of contaminated soil from field sites must be tested in a certified laboratory as part of the soil verification procedures. Details of parameters to be analyzed in the tests are provided in § 6.6 of this Part.
C. Fingerprint Analysis and Testing Inspection, sampling, and testing of soil arriving at the facility shall be performed. Details of the inspection and the parameters to be analyzed in the tests are provided in § 6.7 of this Part.
D. Sampling of Incoming Loads at Processing Facility for Fingerprint Analysis Appropriate sampling of soil arriving at the facility shall be performed in order to adequately fingerprint the soil and minimize the potential of accepting hazardous waste. Details of fingerprint sampling are provided in § 6.8 of this Part.
E. Transportation Practices 1. Measures shall be employed to minimize precipitation run-on, prevent loss of soil or contaminants from the truck, and prevent a spill of material, while in transit. This applies to incoming soils and outgoing rejected contaminated soil or processed soil. Recommended measures include:a. A secured cover placed over the soil.b. A gate sealing method to prevent leakage of any run-off of soil contaminant.c. A chain wrapped around the gate, as an additional securing feature to prevent the weight of the load from forcing open the gate.2. Additional measures may be required by other states, when interstate transfers are involved, and if the affected state(s) regulates this soil as a hazardous waste. It shall be the responsibility of the soil processor to inform the transporter, in advance, of the need to comply with these practices. Failure of the transporter to follow these instructions shall be grounds for load rejection by the processor.F. Acceptable Uses of Processed Soil 1. Any material processed by RIDEM licensed solid waste management facilities, or by out-of-state facilities and to be re-used within Rhode Island, may be used for any of the following applications: a. Aggregate in asphalt production.b. Road base material (provided covered by asphalt). Approval must be obtained from RIDEM Office of Water Resources for each site or application where this road base material is proposed to be used.c. Landfill cover material in any licensed RI landfill.G. Limits of Parameters in the Processed Soil 1. Any soil to be used as aggregate for asphalt production within Rhode Island shall meet the specifications of the appropriate party, e.g., RIDOT specifications, when used on public state highways. Periodic testing of the aggregate and/or asphalt shall be performed at the processing facility to demonstrate that the material meets specifications.2. Any soil to be used as a landfill cover or road base material shall have TPH of 300 ppm or less and shall meet any other specifications required by the given landfill operator/owner or by the buyer of the road base material. The landfill must amend its RIDEM operating plan to show it will be accepting this material for landfill cover.H. Sampling of Processed Soil at Processor's Facility Appropriate sampling and testing of the processed soil shall be performed to determine the extent of residual petroleum contaminant in the soil or due to other requirements (if any) of the accepting party. Details of the sampling and test strategy are provided in § 6.9 of this Part.
