RESNA Industries Inc. <br /> Quality Assurance/Quality Control Plan <br /> Revised November 1992 <br /> Combustible Gas/Oxygen <br /> Combustible gas/oxygen meter. Calibration: factory calibrated, field calibrated monthly, <br /> zeroed daily according to manufacturers instructions. <br /> Miscellaneous Measuring Devices <br /> Calibration procedures for any other measuring device used will be documented at the <br /> request of the regulatory authority. <br /> All equipment will be checked daily and replaced as necessary. Instrument manuals and an <br /> instrument log book will accompany equipment into the field. Any calibration, repairs or related <br /> information will be recorded in the log book. <br /> 8.0 LABORATORY QA/QC PLAN <br /> Soil and groundwater samples will be submitted to a State Certified Hazardous Waste Laboratory <br /> for chemical analysis of hazardous constituents. Established QA/QC procedures for analytical <br /> operations will include sample custody procedures, standards of analytical accuracy, analysis of <br /> matrix spikes and method blanks, data reduction, verification of raw analytical data, and <br /> maintenance of control charts to monitor analytical performance. These QA/QC procedures are <br /> outlined in the laboratory QA/QC Plan which is available upon request. Organic chemical <br /> analyses will be performed in conformance with standard procedures established by the United <br /> States Environmental Protection Agency (EPA) in "Guidelines Establishing Test Procedures-for <br /> the Analysis of Pollutants Under the Clean Water Act" (40 CFR, Part 136, October 1984). The <br /> laboratory is periodically evaluated through external performance audits conducted by EPA and <br /> DHS using QC labs. The specific analytical methods to be utilized for purgeable and <br /> semivolatile hydrocarbons analyses are shown on Table 2. <br /> QAQC1092.F L 6 <br />
