EXPORT SOIL-MATERIAL QUALITY REQUIREMENTS

Transcription

1 EXPORT SOIL-MATERIAL QUALITY REQUIREMENTS GENERAL Industrial operations have been conducted on Port of Long Beach property since the 1930s. Though it is unlikely that hazardous substances will be encountered during construction on Port property, soil-materials affected by industrial operations may not be suitable for reuse in all public settings. Accordingly, the Long Beach Harbor Department has established export soil-material quality requirements to ensure that soil-materials removed from Port of Long Beach construction projects and designated for export are suitable for reuse in any commercial or residential development. A soil-materials testing program is needed to support decisions regarding the acceptability of Port soil-materials for unrestricted export; this testing is described in the following sections. The Engineer reserves the right to accept or reject the export of soil-materials on a case-by-case basis, depending upon the nature and location of the construction/soilmaterial source. Therefore, these guidelines may be considered minimum requirements. Meeting these requirements does not guarantee approval for export. SAMPLING LOCATIONS AND FREQUENCY Soil-material samples collected for evaluation for export must represent a worst case; that is, in order to be protective, we need to identify the most contaminated soilmaterials. Information about property use will be used to determine sampling locations. Whenever possible, soil-material samples shall be collected from a minimum depth of 3 feet below the surface of the excavation or stockpile. Sampling frequencies will be specified by the Engineer and will depend upon the total depth and the aerial or linear dimensions of the excavation. At a minimum, one sample point shall be designated for each 200 cubic yards of material. Duplicate samples must be collected and analyzed to confirm that the sampling program is sufficient to represent soil-material quality. One duplicate sample for every ten samples shall be collected and analyzed. If fewer than ten samples are collected, a minimum of one duplicate is required. Duplicate samples shall be collected in separate sample containers, in a location immediately adjacent to the original sample. Samples must be placed in appropriate containers and maintained at appropriate temperatures until delivered to a California-certified analytical laboratory. Appropriate handling procedures are specified in the most current version of USEPA s Test Methods for Evaluating Solid Waste-Physical/Chemical Methods (SW-846). Chain of custody must be recorded for every sample. Copies of the chain-of-custody forms shall be submitted to the Engineer along with the analytical results. 1 revised March 29, 2006

2 ANALYTICAL REQUIREMENTS AND ACCEPTABLE CONCENTRATIONS All soil-material samples will be analyzed using the methods listed in the following table. Maximum concentrations of contaminants or groups of contaminants are also listed. If the Port is aware of possible contamination by a compound that is not included in this list, an analysis of the suspected contaminant(s) must be conducted. EPA Method(s) Analyte Group Maximum Concentration (mg/kg) Total Recoverable Petroleum Hydrocarbons (TRPH) A Organochlorine Pesticides Aldrin Alpha-BHC beta-bhc gamma-bhc (Lindane) Chlordane Chlorobenzilate DBCP DDD DDE DDT Diallate Dieldrin Endosulfan Endrin Heptachlor Heptachlor epoxide Hexachlorobenzene Hexachlorocyclopentadiene Methoxychlor Toxaphene 8082 Polychlorinated Biphenyls (PCBs) Aroclor 1016 Aroclor 1221 Aroclor 1232 Aroclor 1242 Aroclor 1248 Aroclor 1254 Aroclor 1260 Total PCBs revised March 29, 2006

4 indication that high concentrations of one or more contaminants may be present in the soil-materials. Alternative laboratory methods that provide lower detection limits for an analyte of concern may be considered by the Port on a case-by-case basis. DATA REPORTING, REVIEW AND APPROVAL The attached soil-material analysis reporting form (or equivalent) must be completed for each sample. This form provides a summary of the concentrations of contaminants detected in the soil-materials. In addition, laboratory data sheets for field samples and in-lab QA/QC samples must be submitted to the Engineer. All analytical data submitted to characterize the quality of export soil-materials will be reviewed by the Engineer. Meeting the maximum concentration criteria listed in the table shown above does not constitute automatic approval of the material for export. The City reserves the right to observe contractor s sampling activities, and independently sample, analyze, and verify the results of any soil-material analysis submitted for evaluation. 4 revised March 29, 2006
