Ohio officials are advising oil and gas companies to share information on the toxic chemicals they use with local authorities, including first responders.

The Columbus Dispatch reports that Ohio notified companies this month that federal disclosure law trumps a 2001 state law requiring only that the information be filed with the Ohio Department of Natural Resources.

A fellow Republican state official has come out against Gov. John Kasich's proposed tax increase on drillers.

Ohio Treasurer Josh Mandel tells a meeting of the Ohio Oil and Gas Association he believes the governor's proposal to increase the severance tax stands to scare away Ohio oil and gas investment at a critical time.

Mandel's remarks Thursday mark the second time in under a month he has bucked the governor on a major policy issue.

Environmental advocates in Ohio are blasting a newly added energy-bill provision, which they say would limit the rights of drilling opponents to sue energy companies for withholding chemical trade secrets.

Small business owners are salivating at the prospect Ohio might raise up to $1 billion over five years by hiking taxes on natural gas liquids drillers and using the revenue to pay for a general income tax cut. 

The Dayton Daily News reports that natural gas trapped in two shale formations beneath Ohio could mean thousands of new jobs, if activity in other states is any indication.

Pennsylvania,which sits on one of the same shale formations as Ohio, saw gas and oil industries hire 72,000 new people from the fourth quarter of 2009 to the first quarter of 2011.

The newspaper reports that a series of announcements in the last week, including $750 million in land leasing by the Hess Corp. for possible drilling, shows that Ohio is on the cusp of an oil and gas boom.

State parks and other lands in Ohio will be opened to oil and gas drilling under a bill that has passed the state Senate on Wednesday.

The Senate voted 22-10 on the legislation that sets up a commission to oversee oil and gas leasing. It also requires state agencies to create property inventories that could yield potential drilling sites.

The House has passed the bill, but would have to agree to the Senate's changes before it could go to the governor's desk.
