Chevron Richmond Refinery: Accountability on the Road to Compliance
Judith BalminPP224A GIS Final ProjectWinter 2011

Why Richmond? Why Chevron? Why asthma?
• “Richmond’s children with asthma are hospitalized at twice the rate of children from other parts of Contra Costa County”-Mayor Gayle Maclaughlin
• Residents give testimony about impact from refinery emissions: Burning eyes, shortness of breath, bad smells, and residues on windows
• There is an elementary school, 2 housing projects and 25,000 people living within 3 miles of the Chevron Richmond Refinery
• The refinery has been in high priority violation of the Clean Air Act since at least 2006.

Percent Total Lifetime Prevalence for Asthma in California
Rate of ED Visits for Asthma in 2008 in California
CCC has among worst rates of asthma related ER visits in CA

RecapThe Chevron Refinery in Richmond is amongst the worst polluters in CCC
Worst Polluters in CCC in 2009
Nearly all are refineries - The CA Dept Of Heath sites pollution from petrochemicals sources as a major cause of asthma

My Models
Used model to create rasters for asthma percentage and average income by census tract variables
Used model to reclassify my rasters that resulted from both Euclidian Distance and Features to Raster processes

Skills Used• Inset Map – slide 4• Point Graduated Symbol – slide 3 and 4• Geocoding – slide 4 and 7 (clinics and TRI sites)• Creating Indices – slide 5 and 6, Toxic Air Contaminants index created
from individual qualifying substances• Measurement/Buffer – 6 and 10• Geoprocessing – Clipping all throughout• Hotspot Analysis – Slide 7-10• Modeling – 7 (used to create rasters and reclassify)• Original data – Created and imported spreadsheets for geocoding
clinics and TRI sites which I then used to make shapefiles• Metadata – Created metadata for clinics and TRI sites shapefiles
