According to No Frack Ohio, a statewide coalition of anti-fracking groups, Senate Bill 315 has turned "one of the worst fracking bills in America into the worst fracking laws."
The bill was signed on Monday in Akron by Gov. John Kasich.
No Frack Ohio also said:
"Ohioans now know clearly where their representatives at all levels of state government stand – and unfortunately, most are choosing to stand with their donors in the oil and gas industry, rather than their constituents. Gov. Kasich himself has taken over $200,000 from the gas industry, and has now more than adequately repaid the favor.
"SB 315 eliminates all public notice for fracking well permits, opens gaping loopholes in disclosure laws that allow fracking companies to keep toxic chemical cocktails secret from communities, establishes the lowest tax rates on the gas industry in the country, and gags doctors from discussing the health impacts of fracking.
No Frack Ohio is organizing a June 17 protest in Columbus.
