The oil and gas industry got a huge boost when Dick Cheney, the CEO of Halliburton, became vice president in 2001. At the time, fracking was unknown to the broader public. But an energy policy task force Cheney helmed in spring 2001 highlighted fracking's potential, and it recommended a comprehensive exemption to the federal Safe Water Drinking Act for all types of fracking, not just for coalbed methane, which EPA was studying at the time. The EPA cautioned against an overly broad approach.
The Cadmus Group, the contractor hired by the EPA under the George W. Bush administration to study the risk of fracking to drinking water, concluded that monitoring of fracking activities and more information from industry would be needed to quantify the risk.
The EPA decided the study's conclusion should be that fracking did not pose a threat to groundwater and therefore did not require further study or federal oversight.
The Massachusetts firm The Cadmus Group was hired by the EPA under the George W. Bush Administration in 2002 to write its study on fracking. That study would go on to conclude that fracking poses no risk to drinking water. That finding was the basis for the Halliburton loopole in the Energy Policy Act, which exempted fracking from regulation under the Safe Drinking Water Act.
The Halliburton loophole, which exempts fracking from regulation under the Safe Drinking Water Act, was justified by an EPA study about fracking completed under the George W. Bush administration. The study concluded that fracking posed no risk to drinking water.
However, a working draft of the study prepared by a government contractor suggested that fracking could pose risks to drinking water. The EPA changed parts of that draft.
As part of its advanced battery program in the 1970s, Exxon had developed electric motor technology to be used in a hybrid-gas electric vehicle. In 1978, the EEI automotive team created a brochure that showed off to automakers the hybrid prototype Exxon had built with its ACS technology: a Chrysler Cordoba, which got 27 miles per gallon. That was the mileage target that the Environmental Protection Agency required of vehicles by 1985.
In 1979, Toyota entered into a collaboration with Exxon to work together on the oil company's novel gas-electric hybrid drive system. Pages of the work plan can be seen here.
In 1981 Exxon's engineers delivered a hybrid gas-electric Toyota Cressida to Japan. It was outfitted with Exxon's technology that enabled use of an AC (alternating current) motor in a hybrid—cheaper, smaller and more reliable than DC (direct current) motors.
In 1970, Victor Wouk, an independent scientist presented a paper at the Petroleum Chemical Industry conference in Tulsa, Okla. about the challenges and rewards of electric vehicles. The electric car could be "a treat that can be introduced via the bridge of the heat engine/battery hybrid vehicle over the next several decades. Everyone should be encouraged to promote the development of electric vehicles," he concluded.
Wouk built a prototype1974 hybrid Buick Skylark that got 30 miles per gallon, double its regular mileage, and emitted 9 percent of the emissions a typical model did.
