Will the CAAP achieve measurable emission reductions?
All of the measures, by source category, included in the plan, are designed to achieve the maximum possible emissions reductions given the status of various emissions control strategies and the Ports’ authority to require the implementation of those measures. Thus the goals for the reduction in criteria pollutants are tied to unit-based replacements or conversion to better technology. As identified in Section 6 of the Technical Report, using the growth assumptions from CARB’s GMP and the CAAP assumptions for unit-based improvements, by the fifth year (2011), targeted emissions reductions due to implementation are at least 47% reduction in DPM, 45% reduction in NOx, and 52% reduction in SOx from OGV, CHE, and HDV source categories. Currently, there are no health risk standards defined by agencies such as USEPA, CARB or SCAQMD. The Ports have started discussions with the agency Technical Working Group (TWG) to define San Pedro Bay-wide health risk standards as identified in the expanded discussion in Section 2.2. The Clean Air Action Plan contains a milestone for the Ports to develop a San Pedro Bay wide health risk standard with cumulative health risks goals by Spring 2007.
