The Obama administration has proposed the nation’s first federal regulations on hydraulic fracturing.

The new rules apply only to oil and gas wells on public lands. According to the Department of Interior, that is about 100,000 wells. The large majority of fracked wells are located on private land.

“Current federal well-drilling regulations are more than 30 years old, and they simply have not kept pace with the technical complexities of today’s hydraulic fracturing operations,” said the interior secretary, Sally Jewell.

Erik Milito, director of industry operations for the American Petroleum Institute, said, “Despite the renaissance on state and private lands, energy production on federal lands has fallen, and this rule is just one more barrier to growth. A duplicative layer of new federal regulation is unnecessary.”

The regulations take effect in 90 days. The will allow government workers to inspect the cement liners in fracked wells. They will also require companies to disclose the chemicals used in the fracturing process within 30 days after fracking operations have been completed.

The rules set safety standards for storage of fracking chemicals recovered from well, and require companies to submit information on well geology to the Bureau of Land Management.
