Site assessments must be performed as outlined in 40 CFR 280.72 and R311-205 (U.A.C.). If contamination is suspected, additional samples must be collected at the location where contamination is most likely to be present. If groundwater is encountered, a soil sample must be collected, in the unsaturated zone, in addition to each groundwater sample. Soil and groundwater samples must be analyzed for the compounds shown in the following table, using appropriate lab methods. Substance or Product Type Contaminant Compounds to be Analyzed for Each Substance or Product Type ANALYTICAL METHODS1 Soil, Groundwater or Surface Water Gasoline Total Petroleum Hydrocarbons (purgeable TPH as gasoline range organics C6 - C10) EPA 8015 or EPA 8260 Benzene, Toluene, Ethyl benzene, Xylenes, Naphthalene, (BTEXN) and MTBE EPA 8021 or EPA 8260 Diesel Total Petroleum Hydrocarbons (extractable TPH as diesel range organics C10 – C28) EPA 8015 Benzene, Toluene, Ethyl benzene, Xylenes, and Naphthalene (BTEXN) EPA 8021 or EPA 8260 Used Oil Oil and Grease (O&G) or Total Recoverable Petroleum Hydrocarbons (TRPH) EPA 1664 or EPA 1664 (SGT*) Benzene, Toluene, Ethyl benzene, Xylenes, Naphthalene (BTEXN) & MTBE; and Halogenated Volatile Organic Compounds (VOX) EPA 8021 or EPA 8260 New Oil Oil and Grease (O&G) or Total Recoverable Petroleum Hydrocarbons (TRPH) EPA 1664 or EPA 1664 (SGT*) Other Type of analyses will be based upon the substance or product stored, and as approved by the DERR Division Director Method will be based upon the substance or product type Unknown Total Petroleum Hydrocarbons (purgeable TPH as gasoline range organics C6 - C10) EPA 8015 or EPA 8260 Total Petroleum Hydrocarbons (extractable TPH as diesel range organics C10 – C28) EPA 8015 Oil and Grease (O&G) or Total Recoverable Petroleum Hydrocarbons (TRPH) EPA 1664 or EPA 1664 (SGT*) Benzene, Toluene, Ethyl benzene, Xylenes, and Naphthalene (BTEXN) and MTBE; and Halogenated Volatile Organic Compounds (VOX) EPA 8021 or EPA 8260 1 The following modifications to these certified methods are considered acceptable by the DERR Division Director: Dual column confirmation may not be required for TPH and BTEXN/MTBE analysis. A micro-extraction or scale-down technique may be used for aqueous samples, but only for the determination of extractable TPH as diesel range organics (C10 – C28). Hexane may be used as an extraction solvent. *Silica Gel Treatment (SGT) may be used in the determination of Total Recoverable Petroleum Hydrocarbons. NOTE: The sample preparation method and any modification(s) to a certified method must be reported by the laboratory. 4 CONTAMINATED MATERIALS MUST BE DISPOSED AT AN ACCEPTABLE FACILITY: All materials generated from UST closures must be managed and disposed in a manner that does not place those materials in direct contact with the environment. On-site stockpiling of contaminated soils may be required prior to any soil management activities. Any person providing remedial assistance for a fee, including aeration and over-excavation (of more than 50 yd3), must be a Certified UST Consultant. Contaminated soils generated as part of tank removal are to be disposed at the following facility: Address City State Zip Contact person Phone Complete the Facility Site Plat and Sample Information Table on pages 4 and 5 to provide site assessment information. CONTAMINATION INFORMATION If contamination at the facility is suspected or confirmed, the information must be reported to the DERR Division Director at (801) 536- 4100 within 24 hours. The Division of Water Quality must be notified at (801) 536-4300 if Free Product is encountered or if surface water has been impacted. If contamination is confirmed, any person assisting in the remediation process for a fee must be a Certified UST Consultant. SAMPLE INFORMATION TABLE Complete table for all samples to be taken for closure. 1 Soil (SS), Groundwater (GW), or Unified Soil Classification (USC). 2 Approx. depth in feet below grade. The required minimum site assessment samples must be taken at 0-2 feet below the backfill/native soil interface. 3 Contaminant compounds to be analyzed for each sample (from table on p. 3). 4 Appropriate analysis methods for contaminant compound(s) in each sample (from table on p. 3).
