4. EPA NPM Guidance Ambient Monitoring: The CAA requires EPA to review each NAAQS every five years and revise them if necessary. Each revision of the NAAQS provides greater protection of public health and may place new monitoring requirements on EPA’s state, local and tribal partners. The additional funding requested for FY 2013, first sought but not received in FY 2012, will help defray the purchase costs of state and local agencies of new or replacement monitors for ozone, lead, SO 2, and NO 2. Funding of air monitoring, including a proposed transition in funding authorities for PM 2.5 monitoring and changes in the provision of associated program support, is addressed in greater detail in Appendix C of this guidance. The Agency is still in the process of developing a detailed allocation of its monitoring resources. Final allocations will be influenced by the final NAAQS rules and the refinement of existing networks.

5. 40 CFR Part 58, Appendix A… 2.5 Technical Systems Audit Program. Technical systems audits of each ambient air monitoring organization shall be conducted at least every 3 years by the appropriate EPA Regional Office and reported to the AQS. Systems audit programs are described in reference 10 of this appendix. For further instructions, monitoring organizations should contact the appropriate EPA Regional QA Coordinator. Participate and support EPA in every 3rd year Technical Systems Audit (TSA) for State during FY 2012 (OAQPS M07). Andy Johnson 287-7047 Tech: Bob Judge -8387
