Section 250-RICR-140-05-6.7 - Fingerprint Analysis and Testing (Per Section 6.2(C) of this Part)A. Fingerprinting is performed for numerous reasons, including: 1. As a safeguard against outside undesirable or uncontrollable factors, specifically to allow for an assessment of the material being received versus material originally tested at the generator site, for conformity.2. To allow the processor to assess soil arriving at the facility to ensure it is processible, given any limitations of the equipment employed for soil cleaning, processing procedure limitations, and any required limits of contamination in the cleaned material.3. As a personnel safety measure, relative to assessing material flammability, since the material will be handled, stored, and processed.4. As an environmental regulatory measure, i.e., an additional safeguard to prevent the acceptance of hazardous waste and to prevent material from being processed, that is not within the processor's permit of material acceptable for processing.5. As a check on the analysis and testing originally done on soil samples at the generator site.6. As a tool to discourage outside undesirable actions (prior to arrival at the facility) and to encourage proper procedures in the waste acceptance multi-step process.B. Therefore, the minimum fingerprinting requirements shall include: 1. Visual inspection of each incoming truck load of soil, by the processor's employee/representative as it arrives at the processing facility.2. Appropriate sampling and testing of the unprocessed soil (sampling and testing strategies are presented in §§ 6.2(D) and 6.8 of this Part). The actual tests will include, at minimum, soil flashpoint and a PCB test (whenever the field sampling at the generator site included PCB testing and also at the option of the processor). Other additional tests relative to other parameters may be desirable for a more complete fingerprint, on a case-by-case basis, per the suspected contaminant in the soil at the generator site, as well as other factors. The processor should indicate the normal testing protocol for these various cases. Also, RIDEM may require additional tests, based on the conditions of the processor's permit.3. Wherever the term "full scan lab tests" is mentioned in § 6.8 of this Part (which discusses fingerprint sampling and testing strategies) this shall include at minimum, flashpoint, total petroleum hydrocarbons (TPH), volatile organic compounds (VOC) including separate tests for halogenated and non-halogenated VOC, EPTOX metals, (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) PCB, cyanide and pH (see §§ 6.8(A)(4)(b), 6.8(A)(4)(c), 6.8(A)(5)(b) and 6.8(A)(5)(c) of this Part, where full scan lab tests apply).4. The processor shall notify all parties involved in the steps leading up to arrival of soil at the processor's facility, including the generator, excavator, and transporter that fingerprinting procedures will be employed (with associated potential for rejection of soil).250 R.I.
