The present particulate monitoring system is different from what would be used to measure for the proposed new standard. Any assessment today of how the proposed new particulate standard would affect the state could only be based on rough estimates. It will take at least two years to establish the monitoring system needed to provide firm statewide data under the new standard. After the new standards are adopted in June, and once the state's air quality status under them is understood, Ecology will carefully consider whether regulatory changes are needed to meet clean air goals. While only health may be considered in setting the standards themselves, other factors, such as cost, may be weighed in deciding how to implement the standards.
Ecology encourages public involvement whenever it considers changes to air quality rules or plans.
Input will be sought from the general public and the business, environmental and health communities. We encourage others to do so as well.
