PRESENTATION ON THE UPDATED DRAFT HEALTH RISK ASSESSMENT FOCUSING ON DIESEL PARTICULATE MATTER EMISSIONS AT THE DISTRICT'S MARINE CARGO TERMINALS
Body
EXECUTIVE SUMMARY:
The Maritime Clean Air Strategy (MCAS) includes a vision of "Health Equity for All" with specific aspirational goals and objectives to reduce pollution from maritime-related activities and industries. In support of this vision, one of the MCAS's objectives is the identification of existing health risk levels based on activity at the Tenth Avenue Marine Terminal (TAMT) and the National City Marine Terminal (NCMT) (MCAS - Health Objective 1). Health risk models typically estimate cancer risk as a factor of "per million" people (e.g.,10 per million). The District's Updated Health Risk Assessment (Updated HRA), using the 2019 emissions inventory prepared for the MCAS, identifies the "maximum" risk based on 30-year residential exposure, the point of maximum health impact, or the location where the maximally exposed individual resident is located assuming exposure to emissions for 30 years. District Staff's draft presentation is included as Attachment A.
The MCAS also has an objective of providing the San Diego Air Pollution Control District (SDAPCD) and the California Air Resources Board (CARB) with the District's health risk assessment and to assist them with preparing a cumulative health risk assessment for the larger AB 617 Portside Community (MCAS - Health Objective 2).1 The AB 617 Portside Community's Regional Air Toxics Modeling will include the collective cancer risks at all census tracts in the Portside Community from multiple emissions sources within the San Diego Region and beyond. More specifically, CARB's Regional Air Toxics Modeling will include on-road sources (such as freeways and major arterials), stationary sources (such as power plants and industrial facilities), areawide sources (such as construction and agricultural equipment), and off-ro...
