PSCAA Regulation III + NESHAP Subpart GG-ready media for the Boeing widebody plant, Naval Station Everett, and Snohomish County collision

Everett is the home of Boeing's widebody assembly, the 777 and 787 lines run out of the Everett plant, the largest building in the world by volume, and the surrounding Snohomish County aerospace tier-supplier base feeds both the Everett widebody work and the Renton 737 line further south. Layered on top, Naval Station Everett (the Navy's largest installation in the Pacific Northwest north of Bremerton) drives military fleet and equipment finishing demand, and the Snohomish County collision belt runs across Everett, Lynnwood, Marysville, and Mukilteo. PSCAA documentation rigor applies across the entire footprint. We carry kits sized for both the aerospace tier-supplier population running Subpart GG and the Snohomish County collision belt running PSCAA Regulation III.

Quick answer

Everett paint booths run under Puget Sound Clean Air Agency (PSCAA) Regulation III plus federal NESHAP Subpart GG for aerospace coatings, a critical regulatory pairing here because Boeing's Everett plant assembles 777 and 787 widebody aircraft, with the broader aerospace tier-supplier base across Snohomish County running booths under Subpart GG with 3-stage chromate filtration. Washington L&I covers worker safety. Filter selection follows two paths: PSCAA-compliant kits for collision shops and 3-stage chromate filtration for Subpart GG aerospace booths.

How Everett shops choose filters

PSCAA Regulation III sets the operating expectations for spray-finishing sources in King, Pierce, Snohomish, and Kitsap counties. The Snohomish County footprint includes Everett and the broader aerospace tier-supplier base, which runs paint booths under federal NESHAP Subpart GG (the chromium aerospace coatings rule) with 3-stage filtration including HEPA-class final stages and stringent capture documentation. Filter selection in those booths is engineering-driven first and PSCAA-compliant by default. The 25-entry filter media taxonomy on this catalog separates the aerospace 3-stage Subpart GG kits from the standard PSCAA collision kits explicitly so the wrong SKU cannot land in the wrong cart. Match booth brand and model to verified fitment, document the cadence, file the spec sheet, Subpart GG capture data for aerospace, PSCAA-relevant capture data for collision.

Climate & replacement cycles

Everett shares Seattle's marine west coast climate with somewhat heavier annual precipitation given the more northern Snohomish County location. The wet season, roughly October through April, sustains relative humidity above 70 percent through most workdays with substantial rainfall accumulation. The dry season, June through September, runs sunny and warmer with notably lower humidity, and intake cycles stretch back toward catalog baseline. Aerospace booths under Subpart GG run closer to a fixed engineering cycle independent of climate; collision booths under PSCAA see the seasonal swing meaningfully. Possession Sound and the Snohomish River delta add modest marine-aerosol exposure to waterfront facilities. Set subscription cadence with the seasonal swing in mind for collision; aerospace cycles run on the engineering spec.

Regulatory landscape

Four regulatory layers shape filter purchases in Everett. PSCAA holds primary responsibility under Regulation III for surface-coating sources in Snohomish County, with permits administered locally and inspections conducted on a rolling basis. WA Ecology sets statewide air-quality rules under WAC 173-400 that PSCAA implements regionally. Federal NESHAP Subpart GG applies to aerospace coatings facilities under EPA authority with implementation handled through PSCAA in the Snohomish County footprint. Washington L&I, operating as a state-plan jurisdiction under WAC 296-67, administers worker-safety enforcement with attention to filter integrity, ventilation, and electrical classification. The clean compliance posture for any Everett shop is a recurring delivery cadence with metro-tagged packing slips, a brief technician install log at the booth, and the relevant spec sheets, Subpart GG capture data for aerospace booths, PSCAA-relevant for collision, on file.

Who buys filters in Everett

Everett filter demand concentrates in four distinct populations. The first and largest by volume is the aerospace tier-supplier base, Boeing's Everett widebody plant directly plus the surrounding tier-1 and tier-2 supplier base across Snohomish County, with paint booths running under NESHAP Subpart GG and 3-stage chromate filtration. The second is the Snohomish County collision belt, independent body shops and multi-shop chains across Everett, Lynnwood, Marysville, Mukilteo, Mill Creek, and Edmonds, running standard PSCAA-compliant collision booths. The third is Naval Station Everett military fleet and equipment finishing supporting the Navy's Pacific Northwest operations under federal environmental authority. The fourth is the Possession Sound and Snohomish waterfront marine refinishing presence.

Everett filter FAQs

What's the difference between a PSCAA-compliant kit and a NESHAP Subpart GG kit?

A PSCAA-compliant kit is sized for the booth brand and model and ships with media whose published capture efficiency satisfies the agency's surface-coating requirements. A NESHAP Subpart GG kit is sized for an aerospace coating booth running 3-stage filtration with HEPA-class final stages and full chromium-capture documentation. The Subpart GG kit costs more per cycle and ships with capture-test data formatted for federal aerospace recordkeeping. The catalog separates them explicitly so you cannot accidentally put a collision-class kit in an aerospace booth.

I'm a Boeing tier-1 supplier in Everett with a finish booth — Subpart GG applies?

If your booth is being used to apply chromated primers or topcoats covered under the aerospace coatings NESHAP, yes — your shop falls under Subpart GG regardless of size. The catalog flags Subpart GG-rated kits explicitly and includes capture-test documentation in every shipment. If your booth is not running chromated coatings, the more general PSCAA-compliant kits cover you under Regulation III without the aerospace overhead.

How often should I replace filters in an Everett collision booth?

Everett collision booths typically run intake every 30 to 50 days under normal volume during the wet season (October through April), with cycles stretching to 45 to 65 days through the dry summer months. Exhaust runs 75 to 110 days. Aerospace Subpart GG booths run closer to a fixed engineering cycle independent of climate. Subscriptions auto-tune by ZIP and shop type.

Do you ship next-day to Everett, Lynnwood, and Marysville?

Standard shipping reaches all Snohomish County ZIP codes in one to two business days from our regional warehouse. Next-day is available on select kits to Everett, Lynnwood, Marysville, Mukilteo, Mill Creek, Edmonds, Bothell, and Mountlake Terrace ZIP codes; the cart surfaces the option at checkout when your address qualifies. Subscription deliveries land on the cadence you set with one-click pull-forward for PSCAA inspection windows.

I do paint work for Naval Station Everett — does the same PSCAA documentation apply?

Federal facilities like Naval Station Everett operate under federal environmental rules administered through DoD and EPA channels rather than directly under PSCAA. Civilian shops doing contract work for the Navy still operate under PSCAA authority for their own permits and recordkeeping. If your booth is on-base, your environmental documentation flows through your facility's Navy environmental office; if your booth is off-base doing contract work, PSCAA applies to your operation and the Navy spec applies to your finished product.

Are there filter differences between an Everett aerospace booth and a Lynnwood body shop?

Yes, substantially. Everett aerospace booths covered under Subpart GG run 3-stage filtration with HEPA-class final stages and capture-test documentation in every install record. Lynnwood body shops run on PSCAA-compliant media tuned for the booth brand and collision-volume cadence. The two kits are not interchangeable. The catalog separates them explicitly and the Filter Finder routes you to the correct family based on the booth nameplate and the coatings you spray.
