Bristol Area Air Quality Sample Clauses

Bristol Area Air Quality. EPA has reviewed the ambient air monitoring data for the Bristol Area in accordance with the provisions of 40 CFR part 50, Appendix R. All data considered are complete, quality- assured, certified, and recorded in EPA’s Air Quality System (AQS) database. This review addresses air quality data collected in 3-year period of 2009–2011 which are the most recent quality-assured data available. 40 CFR part 58, Appendix D, Section 4.5, states that ‘‘At a minimum, there must be one source-oriented State and Local Air Monitoring Station site located to measure the maximum Pb [lead] concentration in ambient air resulting from each non-airport Pb source which emits 0.50 or more tons per year * * *.’’ The Exide Technologies facility in Bristol is responsible for operating the monitors that meet this requirement. EPA’s review shows that Exide has been exceeding the minimum monitoring requirement of one monitor, and is currently operating three Federal reference method (FRM) source-oriented monitors at the facility, which meet the quality assurance requirements of 40 CFR part 58, Appendix A. In addition, the State of Tennessee is also operating one additional source-oriented FRM monitor (AQS ID 47–163–3004, identified in Table 1) at the Exide facility. The State’s monitor originally operated from January 1, 2009 through December 31, 2009 (AQS ID 47–163– 4002). Beginning January 1, 2010, Tennessee’s monitor was relocated 0.3 miles to its current location, approximately 10 feet from Exide’s design value monitor (47–163–3001), which is an area of expected maximum concentration at the site. Table 1 shows the 2009–2011 design values at the Bristol Area monitors (the metrics calculated in accordance with 40 CFR part 50, Appendix R, for determining compliance with the NAAQS) for the 2008 lead NAAQS. It also shows the maximum 3-month rolling average for each individual year.
