The Contractor shall collect at least one representative sample <br /> 17 from each container. The Contractor may choose to collect a composite sample of each I <br /> 18 container, but the composite sample must consist of several collection points (a <br /> 19 minimum of 3 random samples) that are representative of the entire contents of the <br /> 20 container and representative of the characteristics of the type of waste in the container. <br /> 21 In accordance with WAC 173-303-040, a representative sample means "a sample <br /> 22 which can be expected to exhibit the average properties of the sample source." <br /> 23 <br /> 24 The debris shall be tested for metals using the Toxicity Characteristics Leaching <br /> 25 Procedure (TCLP) and EPA Methods 1311 and 6010. At a minimum, the materials <br /> 26 should be analyzed for the Resource Conservation and Recovery Act (RCRA) 8 Metals <br /> 27 (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver). Pursuant <br /> 28 to the Dangerous Waste (DW) Regulations Chapter 173-303-90(8)(c) WAC, "Any waste <br /> 29 that contains contaminants which occur at concentrations at or above the DW threshold <br /> 30 must be designated as DW." All material within each individual container or <br /> 31 containment system that designates as DW shall be disposed of at a legally permitted <br /> 32 Subtitle C Hazardous Waste Landfill. All material within each individual container or <br /> 33 containment system that designate below the DW threshold, will be designated as <br /> 34 "Solid Waste" and shall be disposed of at a legally permitted Subtitle D Landfill. <br /> 35 Disposal shall be in accordance with WAC 173-303 for waste designated "Dangerous <br /> 36 Waste" and pursuant to WAC 173-350 for waste designated as "Solid Waste". <br /> 37 <br /> 38 6-09.AP6 <br /> 39 Section 6-09, Modified Concrete Overlays I <br /> 40 April 4, 2016 <br /> 41 6-09.3(8)A Quality Assurance for Microsilica Modified and Fly Ash Modified <br /> 42 Concrete Overlays <br /> 43 The first sentence of the first paragraph is revised to read the following two new sentences: <br /> 44 <br /> 45 The Engineer will perform slump, temperature, and entrained air tests for acceptance in <br /> 46 accordance with Section 6-02.3(5)D and as specified in this Section after the Contractor <br /> 47 has turned over the concrete for acceptance testing. Concrete samples for testing shall <br /> 48 be supplied to the Engineer in accordance with Section 6-02.3(5)E. <br /> i <br /> AMENDMENTS TO THE 2016 STANDARD SPECIFICATIONS BOOK <br /> Revised: 8/1/16 <br />
