3.  Provide data to make pollutant risk assessments of adverse effects to natural resources (AQRVs).  Determine compliance with NAAQS standards and critical loads  Determine trends that assist in compliance predictions, policy objectives, and regional assessments at rural parks.  Provide specific answers from special studies that assist modeling, rural pollution transport issues, SIP development, and national control strategies.  Provide timely information to protect public health in the parks ARD Air Quality Monitoring Objectives Air Resources Division

4. Three-tier monitoring: core for trends, baseline, targeted Co-locate monitoring for efficiency and data use Use partnerships to maximize cost sharing Set primary objectives for each site, time frame follows Target the monitoring by defining the information needs Parameters and quality of data to meet the need Monitoring Concept Changes Air Resources Division

5. Layers of Monitoring PurposeCharacteristics Time frame 1. Trend Long-term trends for rural regions Meets policy & performance needs Stable sites that have regional presentation and are not near significant sources; multiple measurements and network monitors collocated; strong park support with an active AQ program. Several decades 2. Compliance Determine exceedances of the NAAQS and non- attainment status; supporting information on critical loads Meets regulatory requirements; significant partnerships with EPA and State agencies. 4 – 15 years 3. Targeted Provide information that supports policies, decisions, plans, or actions that lead to improved air quality Survey monitoring to provide baseline pollutant data and to challenge the model estimates; multiple pollutant monitoring that investigates issues of source apportionment, transport, response to emission control changes, and other policy- relevant research Less than 5 years (timeline specified in proposal) Define Monitoring by a Layered Structure Each monitor must be defined by its layer, purpose, and timeline.
