bear a disproportionate burden of pollution and, therefore, suffer from greater environmental health risks. Because Richmond is an air pollution hotspot, Richmond residents have applied different strategies since the 1980s to try to improve local air quality. The first EJ movement in the area started in the late 1980s, when the activist tried to stop construction of a garbage incinerator near North Richmond. Sixteen years later, local citizen utilizes “Bucket Brigades” to document a handful of criteria air pollutants such as sulfur dioxide (SO2), carbon monoxide (CO), nitrogen dioxide (NO2), and ozone (O3).This study involves citizens to actively collecting the samples of emissions from Chevron's refineries, especially during accidents, fires, leaks, and explosions. The “sniffers” alert the “samplers” to collect the air samples when they notice a problem. The “samplers” then contact the Coordinator to check the bucket and perform the paperwork before submitting the samples to the Laboratory, in which the results will be reported to CBE, an environmental justice organization. The “Bucket Brigades” did not only raise the awareness local citizens to fight against the air pollution in their area but also their participation. As the number of activists and participants grew in numbers, their position in the battle against environmental injustice was further fortified with the election Green-party mayor of Richmond, Gayle McLaughlin, as well as three new council members sympathetic to their cause in 2008. In July 2008, despite the council failing to halt the Chevron's plan to build more refineries in the area due to rising gasoline prices during that time, the council succeeded to acquire $61 million from the oil company for community programs. Due to great forces from the local communities and fellow EJ activists in Richmond area, Chevron has been making progress to embrace cleaner environment. In 2005, local activists managed to convince Bay Area Air Quality Management District to tighten the air pollution regulations by increasing the frequency of fines of facility incidents. Since then, Chevron has been flaring 10 times less than before. On top of that, Chevron has invested $150 million for building gas turbine in order to reduce air emission, increase energy efficiency, as well as provide most electrical and steam power Chevron requires to operate. Wilmington, Los Angeles Bonnoris noted, “The environmental justice movement posits that the distribution of environmental harms and benefits should be fairly apportioned among all communities”. As Bonnoris argued, the burden of air
