Guidance for the Future Use of NASN (This Guideline Replaces OAQPS Number 1.2-020)

摘要

This guidance is a replacement for OAQPS 1.2-020, 'Guidance for Decentralization and Continued Operation of the NASN,' September 1974. This material should clarify the integration of the NASN into the ambient monitoring program discussed in the draft Air Monitoring Strategy Document and should be used by Regions in their evaluation of state and local monitoring programs.
