Judith Balmin – MPP ‘12
Intro to GIS - Winter 2011
CCC is north of Oakland in the SF Bay Area. It is home to great diversity
As well as to oil refineries, chemical plants—over all 31 different sites registered with EPA TRI program
Total population in 2008: 1,029,703
How bad is it?
Lets look at the obvious equity issue for a moment:
Wealthier households are not located near industry and subsequently are not as directly exposed to harmful emissions that Department of Health identifies as factors in why people get asthma.
The worst polluters are all refineries except for one. The CA Dept Of Heath sites pollution from petrochemicals sources as a major factor that causes asthma.
But letsnot be hasty…
Nothing shocking was revealed by the TAC index. The biggest general TRI emitters are emitting the most TACs as well. Asthma suffers need only worry about 10,000s of tons of TACs instead of 100,000s of TRIs (unless they are worried about Cancer also. That’s a different story).
Iderived the TAC index by isolating the substances amongst the TRI substances that are defined by the CA EPA Air Resources Board to be Toxic Air Contaminants. These are: Lead, Nickel, Ethylene, Carbon Tetrachloride, Benzene, and Chloroform.
Not exactly what I was hoping to do, but here we can see which sites are in close proximity to low income areas and the highest incidence of residents experiencing asthma symptoms
