• The Department of Revenue's exemption eligibility page returned HTTP 403, so the program's criteria and any participant information were not read.
• No participant or certificate list was located: the exemption's accountability data is filed through annual tax performance reports under RCW 82.32.534, which were not obtained, so no individual exemption recipient is named in this packet.
• RCW 82.08.986 and Substitute Senate Bill 6231 on expiring data center exemptions were seen only in search results and were not opened.

• Ecology's list covers only facilities Ecology itself regulates; the page states it is not a complete list of every data center in Washington and directs readers to local clean air agencies for other counties. No local clean air agency (for example Puget Sound Clean Air Agency, Spokane Regional Clean Air Agency or Benton Clean Air Agency) was searched.
• The current Microsoft Columbia order 25AQ-E009 was not read; the order read for that site, 22AQ-E006, is listed as rescinded.
• Approval orders for the East Wenatchee, Cle Elum, Ellensburg, Moses Lake and Olympia sites were not downloaded; those candidates rest on the Ecology list entry alone.
• No water withdrawal, discharge, stormwater or building permit record was searched for any Washington data center.

• No City of Quincy, Grant County, Douglas County, Chelan County or Pierce County planning or council record was searched.
• The Walla Walla County staff report, SEPA checklist and site plan behind SDP26-01 were not obtained, so no parcel number, building count or capacity figure is available for that project.

• No port, city or county agreement document was retrieved for any Washington site.

• The City of Richland option agreement for the Atlas Agro campus was not obtained.
• The session's web search budget was exhausted before this family could be searched directly; the one logged query was run while working the Oregon packet and surfaced the Port of Walla Walla overview document.

• Nine Salcido Enterprises crypto-mining records across Grant, Chelan and Douglas Counties were reviewed in the extract table and left out as crypto mining with no evidenced AI or HPC conversion; only one crypto site (Merkle Standard Usk) was carried forward as an explicit rejection.
• Three power_generation records in the extract (Energy Northwest Cascade Advanced Energy Facility, Goldendale Energy Storage Project, Helion Orion) were reviewed and left out as generation projects rather than data centers.
• Seattle, Tukwila and Spokane colocation records (Digital Realty SEA1, Sabey Intergate.East Buildings 1 and 5, Sabey Intergate.West Buildings A and C, H5 Seattle, Lumen Spokane, TierPoint Spokane) were not individually examined and are not candidates.
• No directory listing service was consulted in this pass.

• The session's web search budget was exhausted before this family could be searched directly.
