Implementation of Revised Air Quality Standards for Ozone and Particulate Matter

President Clinton directed the EPA Administrator to implement new ozone and particulate matter air quality standards in a flexible, cost-effective manner. The memorandum establishes specific implementation principles, timelines for rulemaking, and an attached interagency plan for transitioning to stricter 8-hour ozone and new PM2.5 standards while minimizing burdens on states and businesses.

Role pressure

MixedDownstream manufacturer — Cost cap of $10,000/ton and regional cap-and-trade options provide flexibility, but new 8-hour ozone and PM2.5 standards expand regulated universe
ProtectiveProject developer — Transitional classification and streamlined NSR reduce planning burdens for areas in regional strategies; early action rewarded
ProtectiveEquipment supplier — EPA funds ~1,500 PM2.5 monitors and speciation analysis, creating direct procurement opportunity
UncertainDomestic producer — Clean Air Investment Fund concept allows payments in lieu of controls above $10,000/ton, but final structure unspecified

Risks & tensions

Tension between health-based standards and cost considerations: Clean Air Act prohibits cost consideration in setting standards, but implementation emphasizes cost-effectiveness
Legal uncertainty: EPA initially interpreted Subpart 2 would not apply, then reversed after comments—potential litigation risk
Scientific uncertainty acknowledged for PM2.5 health effects may undermine standard durability
Regional vs. local control tension: states may resist federal regional cap-and-trade impositions
Military exemption for smoke/obscurants may create precedent conflicts with environmental groups
Transitional classification creates implementation complexity and potential gaming by states
Bump-up provisions suspended for 8-hour standard may delay accountability for persistent nonattainment
