The correct answer is because accessing oil and gas is a state interest.
The state’s legislature action was allowed by the Constitution of the United States because accessing oil and gas is a state interest.
The city of Denton, Texas –north Dallas- passed a local initiative against fracking. In consequence, the legislature of the state of Texas passed a bill stating that it was the state government of Texas the only one which could regulate the oil and gas industry. The U.S. Constitution supported the state legislature of Texas in matters of deciding what to do in issues of gas and oil, as a state interest. The legislature has the faculty to decide on major issues like those mentioned.
