The<br />
Environment<br />

endangered species. Great blue herons (left), egrets and mallards are some of<br />
the animals that make it their home.<br />
Improving Operations<br />
We continually strive to minimize air<br />
emissions and waste, use resources<br />
and energy efficiently, and minimize<br />
environmental impact.<br />
The Richmond Advanced Recycled<br />
Expansion (RARE) Water Project is<br />
one example of our collabo rative<br />
approach. In drought-prone California,<br />
fresh water has always been a valuable<br />
commodity. Population growth<br />
and stringent environmental regulations<br />
have increased its value. Water<br />
is also an essential component in oil<br />
refining, with each gallon of oil refined<br />
requiring one gallon of high-quality<br />
water. We are the San Francisco<br />
Bay Area’s largest refinery and thus<br />
the largest water customer for the<br />
East Bay Municipal Utility District<br />
(EBMUD), requiring about 11 million<br />
gallons a day.<br />
To reduce water use, the refinery and<br />
EBMUD completed a plant in <strong>2010</strong> to<br />
treat municipal wastewater for our<br />
steam-producing boilers. Each day,<br />
RARE sends 3.5 million gallons of<br />
treated wastewater to the refinery,<br />
in addition to the 4 million gallons<br />
of reclaimed water already used in<br />
the refining process. RARE saves<br />
enough drinking water to serve about<br />
a quarter of Richmond’s population<br />
and could reduce severe rationing<br />
in future droughts. “This cooperative<br />
effort,” said Lesa McIntosh, an<br />
elected board director of EBMUD,<br />
“will benefit water customers well<br />
into the future.”<br />
Refinery air emissions have been a<br />
source of concern for the community.<br />
By installing new technologies and running<br />
plants more efficiently, we have<br />
reduced regulated air emissions by<br />
70 percent since the 1970s. A refinerywide<br />
flare-minimization program that<br />
began in 2007 has helped decrease<br />
flaring by more than 97 percent. As the<br />
region’s largest refinery, the Richmond<br />
Refinery represents approximately<br />
38 percent of oil refining capacity in<br />
the Bay Area but less than 1 percent<br />
of the volume of vented gas flared<br />
in 2009.<br />
While we have made progress, there is<br />
still work to be done. “Reestablishing<br />
a strong relationship and trust won’t<br />
happen overnight, and we are deeply<br />
committed to fulfilling that goal,” Coyle<br />
said. “We’ve recently taken some significant<br />
steps, but this commitment is a<br />
marathon, not a sprint.”<br />
Our efforts to reduce<br />
flaring and increase<br />
water efficiency in<br />
Richmond illustrate our<br />
continued commitment<br />
to minimize pollution<br />
and waste, conserve<br />
natural resources, and<br />
reduce the environmental<br />
impact of our<br />
operations.<br />
Across the company, we developed<br />
a corporate environmental<br />
stewardship process that provides<br />
a consistent, systematic,<br />
risk-based approach to managing<br />
aspects of the environment,<br />
including air, water, biodiversity<br />
and waste.<br />
For example, in <strong>2010</strong>, we developed<br />
an integrated, corporatewide<br />
freshwater management plan<br />
to enhance current activities on<br />
water stewardship.<br />
