15 May 2006 <br />AGE-NC Project No. 06-1414 <br />Page 3 of 5 <br />Septic tank cleaning and inspection; <br />Soil boring permitting and pre-field work activities; <br />Soil sampling and analysis; and <br />Preparation of a report of findings. <br />3.1. SEPTIC TANK CONTENTS TREATMENT AND DISPOSAL <br />AGE will treat fecal coliform waste in the septic tank with 25 gallons of chlorine bleach at a ratio <br />of 35 gallons waste to one gallon of 13% chlorine bleach. The treated waste will then be transported <br />by a registered hazardous waste hauler under a hazardous waste manifest for treated septic tank <br />contents, and properly disposed of at a registered hazardous waste disposal facility. <br />3.2. SEPTIC TANK CLEANING AND INSPECTION <br />AGE will use high pressure water and a cleaning agent to wash the interior of the septic tank to <br />remove any solids, residues and odors left after emptying the tank. The rinseate will be pumped, <br />hauled and disposed of with the treated septic waste. Once the interior of septic tank is dry, an <br />inspection will be scheduled with SJCEHD. <br />3.3. SOIL BORING PERMITTING AND PRE-FIELD WORK ACTIVITIES <br />A site assessment boring permit will be obtained from the SJCEHD for all on-site boring locations. <br />In addition, a health and safety plan will be prepared in accordance with Occupational Safety and <br />Health Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational <br />Safety and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, <br />1985). <br />3.4. SOIL SAMPLE COLLECTION AND ANALYSIS <br />AGE proposes to advance two soil borings utilizing Geoprobe "direct-push" techniques: one boring <br />will be advanced angling beneath the septic tank, and one boring will be advanced in the seepage pit. <br />The samples will be collected from 1 to 2 feet into native soil at each location. If ground water is <br />encountered, a water sample will be collected for possible analysis. The proposed boring locations <br />are illustrated on Figure 2. <br />Advanced GeoEnvironmental, Inc.
