Design and Operations Plan Western Gravel E & P Waste Disposal Facility Drill Cuttings /Mud PCS • Resource Conservation and Recovery Act (RCRA) total metals including arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver • Volatile organic compounds (extended suite of VOCs) including BTEX • Semi - volatile organic compounds (SVOCs) including polynuclear aromatic hydrocarbons (PAH) if TPH results exceed 5,000 milligrams per kilogram (mg/kg). • Total petroleum hydrocarbons (TPH) for diesel range organic (DRO) compounds, gasoline range organic (GRO) compounds, and/or oil and grease. • Radiological (i.e., gross Alpha/Beta, < 40 Pico curries per gram [pCi /g] will be accepted for disposal). • Paint filter • Ignitability (Flashpoint) • Resource Conservation and Recovery Act (RCRA) total metals including arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver • Volatile organic compounds (extended suite of VOCs) including BTEX • Total petroleum hydrocarbons (TPH) including gasoline range organic (GRO) compounds, diesel range organic (DRO) compounds, and/or oil and grease based upon type of petroleum product released. • SVOCs including PAH if TPH results exceed 5,000 mg/kg. • Radiological (i.e. gross Alpha/Beta), if PCS origin is from an E &P facility. • Paint filter • Ignitability (Flashpoint) It should be noted that, gross Alpha/Beta is considered a good screening method for a wide spectrum of radioactive isotopes. Sample preparation includes drying, acid digestion, and analysis. Since saturated materials will be amended as needed prior to placement, paint filter tests are deemed unnecessary. It should be noted that a certain degree of soil amendment must be conducted prior to hauling in order to prevent liquid release from haul truck dump bodies during transport. Analytical reports must be complete, legible, and understandable. Analytical data provided by a non -NELAP certified laboratory will not be accepted. 3.9.3 Sample Frequency Sample frequency and analysis is based upon the nature of the specific waste stream. However, the following general guidelines associated with small and large waste generators may be used. • One time generators proposing to dispose small quantities (e.g. 500 cy or less) of PCS must collect samples at a rate of one composite sample per 250 cy. • Generators proposing to dispose larger quantities (e.g. greater than 1,000 cy) of PCS must collect a minimum of three samples per project and one sample every 1,000 cy. • E &P generators proposing to dispose very large quantities (e.g. thousands cy) should consult WGDF in order to determine the sample and analysis frequency based upon anticipated total volume to be disposed. However, in general, one composite sample per 5,000 cy and a two sample minimum per project will be required. NWCC, Inc. October 24, 2011 Page 36 of 51
