Efforts to initiate this Air Quality and Source Apportionment Study go back nearly a decade. In 1999, LAWA began its efforts to study LAX contribution to area emissions. However, the tragic events of September 11, 2001 short-circuited the study just as it was beginning. Since that time, LAWA has worked diligently to re-initiate the Study components, including coordinating with the Environmental Protection Agency (EPA) on partnering with LAWA to help fund and oversee technical components of the work.
The effort to kick-off this project also involved the development of a Technical Working Group (TWG) composed of highly qualified professionals to guide the Workplan and navigate the challenges facing this study. The TWG is comprised of air quality scientists, researchers, and engineers from the U.S. Environmental Protection Agency (EPA), California Air Resources Board (CARB), South Coast Air Quality Management District (AQMD), the State of California Office of Environmental Health Hazard Assessment, Federal Aviation Administration (FAA), University of Southern California (USC), Desert Research Institute, and community organizations. While LAWA retains ultimate decision-making authority and responsibility for the study, the Technical Working Group strives for consensus-based decision-making and has been successful in reaching agreement among all participants on the scientific methods and processes being used to conduct the study.
In February 2008 a contract was awarded to Jacob's Consultancy. Efforts are currently underway to complete the study which is broken up into two main components:
- Technology and Methodology Feasibility Demonstration Project (Phases 1 & 2) - Monitoring conducted at 5 on-airport locations to evaluate techniques ranging from experimental to proven are being evaluated as part of this demonstration phase.
- Long-Term Study (Phase 3) - Using the results of the Demonstration Project, the final phase of work will evaluate and document the contribution of LAX to area emissions.
