MEMORANDUM

SUBJECT: Modern O3

# Instrument Deployment Data
FROM: Russell W. Long (U.S. EPA, ORD, NERL)

TO: O 3 

# NAAQS Review Docket, EPA-HQ-OAR-2008-0699.

The 5 -year review cycle of the NAAQS for criteria air pollutants requires review of existing monitoring methods to determine if they provide sufficient measurement accuracy, precision, specificity, and minimal measurement uncertainty to provide data suitable for protecting public health and to support exposure and health studies.Currently, nearly all compliance monitoring in the U.S. is carried out with UV absorption Federal Equivalent Method (FEM) analyzers.

This document contains performance specifications and deployment information for existing and potential Federal Reference Methods (FRMs) and FEMs for determination of ozone in ambient air.Company
