California is the most highly populated state in the U.S. Within 10 years, California may be home to one in every 7 U.S. residentsDespite the progress made to date and stringent environmental controls, challenges to control emissions and environmental impacts remainCumulative risk: concepts to consider

Western States Petroleum Association*Lets consider where we are now so that we can think about where we can go when considering how to address cumulative impacts in in a regional settingCumulative risk: concepts to consider

Western States Petroleum Association*Key environmental regulations California Environmental Quality Act (CEQA)AB 2588 Air Toxics Hot Spots Program (1987-Connelly) AB 3777 Risk Management and Prevention Plans for Acutely Hazardous Materials ARB portfolio of diesel regulationsLocal environmental regulations (regional boards, city and county planning commissions, and air pollution control districts, air quality management districts) Cumulative risk: background

Western States Petroleum Association*Despite the multiple layers of environmental controls that exist, are there other mechanisms that could be developed to further control cumulative risks? Cumulative risk: can more be done?

Western States Petroleum Association*A framework for consideration:New sources should be permitted with the cleanest, most effective and most efficient emission controlsAll existing sources should be controlled to the best available retrofit controls appropriate to the source Transportation sources (autos, trains, boats, off-road vehicles, construction equipment, airplanes) should also reduce emissions to lowest levels feasible Controls and clean up should not be punitive All sources should contribute to reducing cumulative impacts A robust evaluation process is essentialCumulative risk: can more be done?

Western States Petroleum Association Cumulative risk: can more be done?Conclusion:We cannot force the most recent permit applicants to clean up the cumulative impacts of the past
