Pittsburg and mining, 1800's

In the mid 1800's, affluent businessmen from the East Coast caught word of coal reserves in California. Black Diamond Mines would soon become the most extensively mined coal deposit in the state of California. Mining companies extracted bout 4 million tons of coal.

You can read more about the coal mining industry in the 1800s from  The Great American Stations .

Impaired Water

"When water is contaminated by pollutants, the water bodies are considered impaired. These impairments are related to the amount of pollution that has occurred in or near the water body."

Hazardous Waste

"Waste created by different commercial or industrial activity contains chemicals that may be dangerous or harmful to health"

Cleanup Sites

Environmental Racism

Read it in its' entirety  here .

 Robert D. Bullard  explains why vulnerable communities are targeted by polluting industry.

"Environmental racism....places the burden of proof on the 'victims' rather than the polluters...and fails to develop pollution prevention and precaution processes as the overarching and dominant strategy."


Environmental Justice Legislation

Now that we understand the pollution burden in the vulnerable community of Pittsburg, learn about various environmental justice legislation recently enacted.

Environmental Justice legislation is now being proposed and enacted in local and federal governments.  AB1628  requires "coastal development permit process[es]" including environmental justice impact assessments for all new permits.

National Research Council  Health Impact Assessment  offers guidelines for including environmental justice impacts.

New Jersey set a "gold standard" in  Environmental Justice legislation . Permitting regulations for vulnerable communities are now taking shape.
