Currently, the Everett facility depaints 6 or less completed aircrqfieach calendar year. Therefore, the de painting requirements of the AerospaceNESHAP do not apply to the facility. However, under the Alternate <strong>Operating</strong>Scenario shown below, the Everett facility would depaint more than 6completed aircraft in a calendar year and thus be subject to the depaintingrequirements. Chemical milling maskant application operations subject to theAerospace NESHAP are not conducted at the Everett facility and, therefore,are not included in this section.I August 10, 19991eller from David Kircher, <strong>Puget</strong> <strong>Sound</strong> <strong>Clean</strong> <strong>Air</strong> <strong>Agency</strong>, to Charles Austin, Boeing.2 February 24,2005 email/rom Steve Van Slyke, <strong>Puget</strong> <strong>Sound</strong> <strong>Clean</strong> <strong>Air</strong> <strong>Agency</strong>, to John Fosberg, Boeing.Boeing-Everett <strong>Permit</strong>, issued September 12, 2008,' Administrative Amendment 3: October 10, 20 J 2
