Permit No. 13120Expiration Date: September 12, 2013Page 60f291I. EMISSION LIMITS AND PERFORMANCE STANDARDSThe following tables list the citation for the "applicable requirement" in the second column. Thethird column (Date) contains the adoption or effective date of the requirement. In some cases,the effective dates of the "Federally Enforceable" requirement and the "State Only" requirementare different because either the state (or local authority) has not submitted the regulation to theEPA for approval into the State Implementation Plan (SIP), or the state (or local authority) hassubmitted it and the EPA has not yet approved it. "STATE ONLY" adoption dates are in italicizedfont. When the EPA does approve the new requirement into the SIP, the old requirement will bereplaced and superseded by the new requirement. This replacement will take placeautomatically, with no changes being made to this permit until the permit is renewed. The newrequirement will be enforceable by the EPA as well as the Puget Sound Clean Air Agency fromthe date that it is adopted into the SIP, and the old requirement will no longer be an applicablerequirement.The first column is used as an identifier for the requirement, and the fourth (RequirementParaphrase) column paraphrases the requirement. The first and fourth columns are forinformation only and are not enforceable conditions of this permit. The actual enforceablerequirement is embodied in the requirement cited in the second and third columns.The fifth column (Monitoring, Maintenance & Recordkeeping Method) identifies the methodsdescribed in Section II of the permit. Following these methods is an enforceable requirement ofthis permit.The sixth (Emission Standard Period) column identifies the averaging time for the reference testmethod. The last column (Reference Test Method) identifies the reference method associatedwith an applicable emission limit that is to be used when a source test is required. In some caseswhere the applicable requirement does not cite a test method, one has been added.In the event of conflict or omission between the information contained in the fourth and sixthcolumns and the actual statute or regulation cited in the second column, the requirements andlanguage of the actual statute or regulation cited shall govern. For more information regardingany of the requirements cited in the second and third columns, refer to the actual requirementscited.Boeing-Everett Permit, issued September 12, 2008,' Administrative Amendment 3: October lO, 2012

EMISSION UNIT SPECIFIC REQUIREMENTSPermit No. 13120Expiration Date: September 12, 2013Page 15 of291B. EMISSION UNIT SPECIFIC APPLICABLE REQUIREMENTSThe requirements in Section LB. only apply to the specific emission units cited; however, therequirements in Section LA. also apply to the specific emission units or activities described inSection LB. If a requirement in Section LA. is repeated in this section, then the monitoring,maintenance, and recordkeeping method specified in this section supersedes the monitoring,maintenance, and recordkeeping method specified in Section LA.The first part of each subsection in Section LB. lists a description of the emission activity andidentifYing information about each specific emission point or unit. The identifYing informationincludes the building number, the colunm and door number (grid system for locating points withinthe buildings), a Boeing inventory control identification number (MSS/ID#), the Notice ofConstruction (NOC) number for equipment that has gone through the new source review process,the installation date and a short description of the emission unit. This information, which is initalics, is not an enforceable part of the permit. Because of the size of Boeing and its complexity,the information is provided as an aid in understanding the permit and locating the specificemission point or activity.The following tables list the citation for the "applicable requirement" in the second column.The third column (Requirement Paraphrase) paraphrases the requirements and is not anenforceable condition of this permit. The actual enforceable requirement is embodied in therequirement cited in the second column.The fourth column (Monitoring, Maintenance and Recordkeeping Method) identifies the activitiesthat Boeing shall use to monitor compliance with the applicable requirements identified in thesecond colunm. These methods are described in Section II of this permit. Following the method isa requirement of this permit. In some cases where the applicable requirement does not cite a testmethod, one has been added.Boeing is subject to all the requirements in all the tables listed below. The paraphrasing containedin the third column below is intended to generally state the relevant requirements for the purposesof the table, but is not intended in any way to alter or change the meaning of any requirementreferenced in the second column.In the event of conflict or omission between the information contained in the third column and theactual statute or regulation cited in the second column, the requirements and language of the actualstatute or regulation cited shall govern. For more information regarding any of the requirementscited in the second colunm, refer to the actual requirements cited.Boeing-Everett Permit, issued September 12, 2008; Administrative Amendment 3: October 10, 20 J 2

Coating, Cleaning, and Depainting OperationsDESCRIPTION: This section includes all activities and equipment associated with surfacecoating, cleaning, and depainting operations that have specific applicablerequirements other than the general requirements in Section LAoTheseoperations include coating mixing, application, drying, and curing; spray guncleaning; solvent wipe and solvent flush cleaning; de painting; and materialand waste handling.Examples of equipment involved in these activitiesinclude spray booths, paint hangars, solvent cleaning benches, and guncleaning units. Note that small buckets, pails, and beakers with a capacity of2 gallons or less usedfor cleaning with acetone are exempt from WAC 173-460-060(5). I In addition, cold solvent cleaners using solvents that meet thevolatility thresholds in Puget Sound Clean Air Agency Regulation I Section6.03(c)(53) are exempt from WAC 173-460-060 since they are exempt fromreview under Agency Regulation 1 Section 6.03.(WAC 173-460 is asupplemental regulation which does not apply to units that are exempt fromreview under Agency Regulation I Section 6.03).2Cleaning, primer application, and topcoat application operations su~ject tothe Aerospace NESHAP (40 CFR Part 63 Subpart GG) are included in thissection. 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 OperatingScenario 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, Puget Sound Clean Air Agency, to Charles Austin, Boeing.2 February 24,2005 email/rom Steve Van Slyke, Puget Sound Clean Air Agency, to John Fosberg, Boeing.Boeing-Everett Permit, issued September 12, 2008,' Administrative Amendment 3: October 10, 20 J 2

The last columnin the table indicates whether Aerospace NESHAP-regulated coatingscontaining inorganic HAPs are sprayed in the unit at the time of permitissuance. However, any of the booths listed below may have such coatingssprayed in them in the future, and in some cases an amendment ormodification to the existing permits may not be needed.Most of the spray coating units listed below are used in aerospace componentcoating operations.
