Management of Material with Previously Unknown Hazardous Substances Sample Clauses

Management of Material with Previously Unknown Hazardous Substances. If the Proponent encounters a previously unknown occurrence of hazardous substances at concentrations greater than applicable cleanup levels and those materials possess field- screening indications of gross contamination (e.g., odor or presence of visible non- aqueous phase liquid (NAPL)), then the Proponent must notify Ecology and the Port contacts in Section 3.1 of the occurrence within 3 business days. Hazardous substances known to exceed cleanup levels within soil or groundwater of the PTM XXX include petroleum hydrocarbon, metals, VOCs, PAHs, dioxins/furans, and acidic pH. Aspect (2013) and Aspect (2014) provide additional details regarding hazardous substances within the PTM XXX, and are incorporated here by reference. After notifying the Port and Ecology, such materials excavated for project purposes must be segregated and managed separately from materials without indications of gross contamination. Excavated materials with indications of gross contamination must be either: (1) properly profiled and disposed of off site in accordance with procedures identified in Section 3.2.3; or (2) sampled to characterize the contamination as described below, and the information presented to Ecology for their determination on its suitability for on-site reuse beneath the XXX-wide cap. To chemically characterize material containing gross contamination for potential on-site reuse, one representative 5-point composite sample will be collected for each 20 cubic yards of material with indications of gross contamination, using industry-standard sampling practices for the material being sampled and the contaminants being analyzed for (listed below). The material may be sampled in situ (that is, before excavation/grading) or sampled from a stockpile after excavation/grading. Each sample must have a unique identification number and, for each sample, the correlation between the identification number and the stockpile or in situ location from which it was collected must be recorded. Characterization soil samples must be submitted under chain of custody to an Ecology-accredited analytical laboratory for the following chemical analyses: • Diesel-range and oil-range petroleum hydrocarbons (by NWTPH-Dx method with silica gel pretreatment); • VOCs by EPA Method 8260; and • The metals arsenic, cadmium, chromium, copper, lead, mercury, nickel, and zinc (by EPA Methods 6000 and 7000).
