Cattle ranchers, developers and others have been working to develop natural gas fields in Texas.

The natural gas boom is expected to grow even larger in the next few years, but the state’s regulators are keeping an eye on the boom.

The U.S. Environmental Protection Agency announced last month that it had approved fracking permits for more than 20 natural gas wells in Texas and Wyoming.

The approval allowed the companies to begin pumping gas to the ground.

But the oil and gas industry has warned that any new drilling will have to comply with strict new regulations.

In a letter to Gov.

Greg Abbott, the American Petroleum Institute, the nation’s largest energy company, wrote that the new permits would only allow companies to inject as much as 1.3 billion gallons of gas per day into the ground in Texas or Wyoming, a relatively small amount compared to the oil, gas and coal industries.

“These permits are not sufficient to meet our goal of 100 percent natural gas use in Texas by 2025,” the letter read.

The letter also noted that the rules would require fracking companies to have a permit in place before they could begin pumping natural gas into the earth.

Environmentalists are concerned that the proposed new rules will drive up energy costs for Texas residents.

The industry is also concerned that drilling permits will only be granted to companies that have already proven themselves in the state, which would mean that companies that already drill in the U.K. would not be able to drill in Texas if the state does not grant new drilling permits.

The Natural Resources Defense Council, which is one of the most vocal opponents of the proposed rules, has issued a statement calling on Abbott to veto the rule.

“The Texas Department of Natural Resources has a long history of overstepping its boundaries and acting in ways that put Texas communities and the oil industry in peril,” said DNR Director Steve McCraw.

“The current proposal will have little to no impact on Texas oil and natural Gas production and development, which are already up by more than 50 percent from the levels seen prior to the moratorium.”

The Texas Association of Petroleum Exporters, which represents companies like BP, Schlumberger and Schlumberggrader, wrote to Abbott to oppose the rules.

“With this rule, the Texas Department has decided to go back on its promise to do all it can to ensure the safety of Texas residents,” the group said in a statement.

“As we have been saying for years, this rule will have an adverse effect on Texas businesses and communities.”
