These State Implementation Plans (SIPs) are the roadmaps to meeting the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) of 0.08 In 1997, EPA first established the 8-hour ozone standard, which replaced the older 1-hour ozone standard (0.12 Source: EPA.

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

Further, the agency said, technical progress has been made in developing technologies and approaches that can reduce NO x emissions beyond the standards put in place in the 2000 rule. (In the final HD Phase 2 rule, EPA had noted the evidence supporting the need for more stringent national NO x emissions standards.).

While reductions in particulate matter tend to produce local health benefits, the scientists found health and agricultural benefits from reduced ozone disperse more widely.

Diesel exhaust contains a variety of harmful gases and more than 40 other known cancer-causing substances. In 2000, the ARB established California’s Diesel Risk Reduction Plan, which aims to reduce diesel emissions to 85% below 2000 levels by 2020. NO x helps create ground-level ozone, or smog.
