Abstract: . . .  the material no differently than a test program sample. PEAs will normally be conducted by the SRI QA Manager or his designee. They may be combined with a TSA or samples introduced separately as appropriate. For example, PE samples for analytical laboratory audits will typically be included by the sampling field team leader with other field samples. In addition to internal PEAs, we anticipate that independent PEAs will be conducted by the EPA QA Manager. GHG Center technical and QA staff will assist in these audits and respond to their findings as required. • Audit of Data Quality - An Audit Of Data Quality (ADQ) is an examination of the data after they have been collected and 100% verified by project personnel. Assessing whether the Data Quality Indicator (DQI) goals specified in the test/QA plan were met requires a detailed review of the recording, transferring, calculating, summarizing, and reporting of the data. An ADQ typically consists of independent verification and tracing of a representative portion of test results and calculations back to raw data and logs. ADQs will be performed by SRI’s QA Manager or his designee for each verification test, and will include at least ten percent of all of the verification data. This ten percent requirement may be relaxed if necessary. An example would be the collection of electronic data over a long period of time that results in the collection of massive amounts of data. In such cases, a systematic sampling approach may be used in . . .
. . .  Technical Systems Audits (TSAs) are "thorough, systematic, and qualitative audits of the measurement system used in environmental data operations", which "are usually performed on the site of the project." The objective of the TSA is to assess and document acceptability of all facilities, maintenance, calibration procedures, reporting requirements, sampling and analytical activities, and quality control procedures. An approved test/QA plan provides the basis for the TSA. Objective evidence is gathered by interviewing personnel, examining records, and observing project activities. An internal TSA will be conducted by SRI’s QA Manager or his designee. Audit findings are brought to the attention of GHG Center management in a written Audit Report. Management will respond by assessing the severity of any problems identified and addressing significant problems by identifying the root cause of the problem and implementing corrective action. A significant problem is one that would cause the test to fail to meet objectives, or would cause results to be unverifiable (e.g., a lack of appropriate documentation of QC tests). TSA Audit Reports will be generated by the SRI QA Manager, and will be reviewed by the GHG Center Director, EPA Project Officer, Page 28 Version 1.4 – March 2003 20 and EPA QA Manager. In addition, we anticipate that independent TSAs will be conducted by the EPA QA Manager. GHG Center technical and QA staff will assist in these audits and respond to their findings as required. . . .
