As directed by the Governing Board at its January 2003 meeting, staff investigated the feasibility of rulemaking regarding cumulative impacts of air pollution beyond current SCAQMD requirements. A Working Group comprised of representatives of key stakeholder groups from industry and the environmental/community groups was formed to provide input to staff regarding these efforts. On September 5, 2003, The SCAQMD Governing Board directed staff to proceed with the Cumulative Impacts Reduction Strategy (CIRS), as outlined in the following White Paper. Cumulative Impacts was a key component of the 2003-2004 Environmental Justice Workplan.
