The Work in this Section consists of the quality Criteria for the acceptance of Imported soil and Re-Use of soil within the project Right-of-Way. B. The Authority or its designee will monitor the Contractor s performance of tasks specified, and will inspect necessary records, reports and procedures. DEFINITIONS A.

2 Imported fill : soil or fill material received from sources outside of the project right-of-way. B. TPH: Total Petroleum Hydrocarbons as either gasoline (TPH-g) or diesel (TPH-d) as analyzed by United States Environmental Protection Agency (USEPA) modified Method Number 8015. C. Volatile Organic Compounds (VOCs): organic compounds (carbon-containing) that evaporate readily at room temperature, which are commonly used in dry cleaning, paint stripping, metal plating, electronics manufacturing and machine degreasing.

3 These constituents are analyzed by USEPA Method number 8260B. D. Metals: The 17 elemental metals as defined by Title 22 and analyzed by USEPA Method Number 6010B. SUBMITTALS A. Refer to GENERAL REQUIREMENTS Section 01 33 00 SUBMITTAL PROCEDURES. B. Contractor- soil Import and Export Sampling and Analysis Plan Required within 150 Days after NTP. QUALITY CONTROL A. State Water Resources Control Board Order No. 99-08-DWQ or National Pollutant Discharge Elimination System (NPDES) General Permit for Storm Water Discharges Associated with Construction Activity (General Permit) Water Quality Order 99-08-DWQ.

California Regional Water Quality Control Board-Los Angeles Region (RWQCB), Interim Guidelines dated May 1996. Expo Rail Operations and Maintenance Facility Imported fill AND soil Re-Use Criteria SANTA MONICA, CA 01 35 45 - 2 D. Port of Long Beach Import fill Quality Requirements dated August 1998. E. California Department of Transportation s (Caltrans) variance for lead-contaminated soils from the California Environmental Protection Agency-Department of Toxic Substances Control (DTSC) dated September 22, 2000.

5 F. DTSC Advisory Letter to the MTA for Acceptance of Ground Cover as Mitigation for Arsenic Contaminated Soils dated May 7, 2004. PART 2 - PRODUCTS Provide products required for Work in accordance with Standard Specifications for Public Works Construction (SSPWC). PART 3 - EXECUTION Imported fill REQUIREMENTS A. Imported fill material should not be received from sites undergoing an environmental clean-up. B. Obtain documentation that the fill source is appropriate for the use as intended. If fill material analytical information is unavailable, ensure that the fill material was analyzed through a California Department of Health Services (DHS)-certified laboratory for appropriate contaminants based on the location of the source area.

6 The documentation should consist of detailed information on previous land use from where the fill was obtained and results of any laboratory and physical testing performed. The report containing this information shall be signed by a California Licensed or Registered Professional ( , registered geologist or Professional Engineer). C. When possible, obtain representative samples from borrow area while the potential fill material is in place prior to removal from the borrow area. For non-stockpiled areas, a minimum of four samples should be collected for areas, which are 2-acres or less.

7 A minimum of 1 sample every acre should be collected from areas ranging from 2 to 4 acres. Areas ranging from 4 to 10 acres, a minimum of 8 samples should be collected. Areas greater than 10 acres should have a minimum of 8 locations sampled with 4 sub-samples per location. D. Stockpiled soil up to 1,000 cubic yards should have one sample every 250 cubic yards. soil stockpiles from 1,000 to 1,500 cubic yards, four samples from the first 1,000 cubic yards and one sample each additional 500 cubic yards should be collected.

8 Stockpiles greater than 5,000 cubic yards a minimum of 12 samples should be collected for the first 5,000 cubic yards and one sample per each additional 1,000 cubic yards should be collected. E. Composite sampling is not acceptable for volatile organic compounds or semi-volatile organic compounds. Composite sampling is not acceptable for in-situ conditions on separate sources or stockpiles. Composite sampling of metals, pesticides, herbicides or polycyclic aromatic hydrocarbons (PAHs) is unacceptable unless the material is stockpiled at the borrow area and originates Expo Rail Operations and Maintenance Facility Imported fill AND soil Re-Use Criteria SANTA MONICA, CA 01 35 45 - 3 from the same source area.

9 Samples, which are composited, should be obtained from the same soil layer. F. Analytical testing for Imported fill areas originating from near existing freeway should include lead by EPA Method 6010B or 7471 and PAHs by EPA Method 8310. Imported fill from areas near mining areas or rock quarries should be tested for heavy metals by EPA method 6010B, asbestos by polarized light microscopy and pH. Imported fill received from agricultural areas should be tested for pesticides (organochlorine pesticides) by EPA Method 8081A or 8080A, organophosphorus pesticides by EPA method 8141A, chlorinated herbicides by EPA method 8151A and metals by EPA method 6010B.

10 Analysis for Imported fill received from residential or acceptable commercial land should be tested for VOCs by EPA method 8021 or 8260B as appropriate combined with EPA Method 5035; semi-volatile organic compounds (SVOCs) by EPA method 8270C; TPH by EPA method 8015M; polychlorinated bi-phenyls (PCBs) by EPA method 8082 or 8080A; and metals by EPA method 6010B. G. Imported fill with detectable concentrations of analytes outlined in Article of this Section that is above the practical quantitation limit is unacceptable fill . H. Imported fill suitable for project use should not exceed the values of heavy metals concentrations of lead and arsenic each at concentrations greater than 50 ppm and 10 ppm, respectively.
