Let me know if I should be sending this to someone else. </span><br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  Thanks</span><br>  <b><u><span style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  Total Enclosure differential Pressure Monitors</span></u></b><span  style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  The revised Lead MACT requires the facility to monitor building (total  enclosure) pressure and maintain the negative pressures below -0.007 inches of  water (63.544(c)(1)). Also, 63.548(k)(3) requires the differential pressure  monitors to be certified by the manufacturer to be capable of measuring  negative pressure in the range of 0.005 - 0.11 inches of water with a minimum  accuracy of +/- 0.001. The facility is having trouble obtaining monitors that  meet criteria. Attached are specifications for two different monitors. These  units appear to meet the accuracy requirement, but the ranges are 0 to 0.1 or  +/- 0.1 (doesn t appear to meet the high range requirement of 0.11). Should  this be of any concern since this is the high range? Do you agree that the  monitors would be acceptable?</span><br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:red'><br>  I think this would be OK. The monitor is able to measure 0.1" H2O rather  than 0.11, with the difference being 0.01. This is a pretty minor difference  and the monitor can still measure well above the level of the standard and  determine whether they're in compliance.</span><br>  <b><u><span style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  Compliance Testing</span></u></b><span style='font-size:10.0pt;font-family:  "Calibri","sans-serif"'><br>  63.543(g) requires the facility to conduct annual lead emission testing. If a  compliance test demonstrates that the lead emitted was less than 0.1 mg/dscm,  then the facility can petition to test within 24 months instead of 12 months.  Typically, compliance testing is required within 180 days after the compliance  date. The compliance date for existing facilities is January 6, 2014. The  facility conducted several test on several different sources during 2012, and  tests results were below the 0.1 mg/dscm limit for requesting a test extension.  Several test are also planned for early 2013. </span><br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  Does the testing schedule (and 24 month extension petition) apply before the  compliance date? </span><br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:red'><br>  No. A source must meet the initial compliance requirements. A source can  request the 24 month extension after the compliance date.</span><br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  HEPA filters were added to some sources after successful testing demonstrated  lead emissions below 0.1 mg/dscrm. Does the facility need to conduct another  test with the HEPAs (emissions should be lower) or may the facility petition to  for the 24 month extension? </span><br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:red'><br>  The extension can be provided from the date of the initial compliance test used  to demonstrate initial compliance by the compliance date.</span><br>  <b><u><span style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  Facility Wide Flow Weighted Average</span></u></b><span style='font-size:10.0pt;  font-family:"Calibri","sans-serif"'><br>  63.543(a) requires the facility to demonstrate compliance with a 12 month  flow-weighted average concentration, calculated each month. </span><br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  It s unclear when the facility should begin calculating this average. It s my  interpretation that the facility should begin calculating this average no later  than the first month after the compliance date? Do you agree?</span><br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:red'><br>  Until 12 monthly values have been collected, the source should use monthly  values rather than a 12 month rolling average. See 63.543(a)(1)-(4).  Specifically, the section dealing with the period before 12 monthly values have  been accumulated is 63.543(a)(2). </span><br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  Thanks you and let me know if you need any additional information or need to  discuss. </span><br>  <br>  <br>  <span style='font-size:10.0pt;font-family:"Calibri","sans-serif"'><br>  [attachment "GE Modus RPM-1 g.pdf" deleted by Nathan  Topham/RTP/USEPA/US] [attachment "Setra Sensing Solutions - 267-Pressure  Transducers.pdf" deleted by Nathan Topham/RTP/USEPA/US] </span></p>    </div>    </body>    </html>
