II. MONITORING, MAINTENANCE, AND RECORDKEEPING Permit No. 13120Expiration Date: September 12, 2013Page 209 of291(iii) For primers and topcoats complying with the organic HAP or VOC contentlevel by averaging, the name of each primer and topcoat, the VOC content asreceived and as applied, the monthly volume-weighted average masses of organicHAP and VOC emitted per unit volume of coating as applied as determined by theprocedures specified in 63.750(d) and (t), and all data, calculations, and test resultsused in determining the values. [40CFR 63.752(c)(4), 9/1/98)Boeing shall comply using methods defined in 40 CFR 63.745(e) if applicable. [40CFR63.745(e), 12/8/00)(i) Aerospace NESHAP Pressure DroplWater Flow Rate Monitoringand Recordkeeping Procedure(i) For affected spray coating operations when inorganic HAPs are sprayed, unlessthe primers or topcoats have inorganic HAP concentration less than 0.1 % forcarcinogens and 1.0 % for non-carcinogens, Boeing shall install a pressure gaugeor water flow meter to continuously monitor:• The pressure drop across dry particulate filter systems while aerospaceprimer or topcoat application operations are occurring, or• The water flow rate of water wash systems while aerospace primer ortopcoat application operations are occurring,[40 CFR 63.751(c), 12/8/00)(ii) Boeing shall read and record the pressure drop or water flow rate once each shiftof operation on a log in accordance with 40 CFR 63.751(c) and 63.752(d) whenspraying primer or topcoat with inorganic HAP regulated under 40 CFR63.745(g), unless the primers or topcoats have inorganic HAP concentration lessthan 0.1 % for carcinogens and 1.0 % for non-carcinogens. [40 CFR 63.752(d),9/1/98)The acceptable range for water flow rate shall be established usingmanufacturer's recommendations or the range will be based on the volume ofwater that has been shown through operational experience to obtain a continuouswater curtain. If the recorded pressure drop exceeds or falls below theBoeing-Everett Permit, issued September 12, 2008; Administrative Amendment 3: October 10, 2012
