The new rules also require oil companies to install hydrogen supply pumps at existing gasoline stations to power fuel-cell cars.
Each hydrogen pump may cost between $1 million and $2 million, according to the air board. Companies affected by the new rule include BP Plc, Chevron Corp., Tesoro Corp., ConocoPhillips, Valero Energy Corp., Royal Dutch Shell Plc and Exxon Mobil Corp.
The requirement may lead to a court fight with the oil companies, said Cathy Reheis-Boyd, president of the Western States Petroleum Association, a trade group whose members include those that would have to comply with the new rules.
“We strongly oppose the clean fuels outlet requirement,” Reheis-Boyd told the regulatory board yesterday.
