Rationale

This item was in danger of expiring at the end of 2025 and was submitted to a reapproved by ballot closing December 1, 2026, with a request for members to vote affirmative with comments. The Chair committed to opening a work item to address comments as well as to perform a comprehensive revision to align the standard with recent revision of the USEPA guidance on use of transfer standards in calibration of ozone monitors. The Chair invites members to participate in the revision effort.
