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 ObjectivesARD Air Quality Monitoring Objectives

Air Resources Division

• 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

Layers of Monitoring Purpose Characteristics

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 StructureDefine Monitoring by a Layered Structure

Each monitor must be defined by its layer, purpose, and timeline.
