Here are more news items about Ohio's Utica shale and drilling:
1. Chesapeake Energy Corp., the biggest player in Ohio, has agreed to sell a pipeline subsidiary to an affiliated partnership for $865 million.
Chesapeake Midstream Partners LP will buy Appalachia Midstream Services LLC, owner of 47 percent of a 200-mile gathering system in the Marcellus shale, from Chesapeake Midstream Development LP.
The system transports 1 billion cubic feet per day of natural gas in Pennsylvania and has 15-year contracts with gas producers, Bloomberg recently reported.
Chesapeake Midstream, based in Oklahoma City, bought $500 million worth of pipelines in the Haynesville shale in Louisiana, Texas and Arkansas in 2010 from Chesapeake Energy, which raises its ownership stake in the pipeline partnership to 46.1 percent from the 42.3 percent with the latest sale.
The partnership "expects to pursue a substantial number of asset dropdowns from Chesapeake in the years ahead," said Chesapeake Midstream CEO J. Mike Stice in a company-issued statement.
2. Colorado is the latest state to require energy companies to disclose the concentrations of toxic chemicals used in hydraulic fracturing or fracking.
It also wants drillers to make public some information about ingredients considered trade secrets.
The new rules, finalized last month, will go into effect in April.
The Colorado rules are similar to the first-in-the-nation law passed by Texas in 2011, but go further by requiring the concentrations of chemicals to be be disclosed.
If Colorado drillers claimed trade secrets, they could still be required to identify the ingredient's chemical family in the case of emergencies.
In recent years, Arkansas, Louisiana, Michigan, Montana, New Mexico, Pennsylvania and Wyoming have proposed or adopted rules on the disclosure of fracking chemicals.
Companies have been fracking for decades but the practice is under new scrutiny.
Fracking requires the use of water, sand and select toxic chemicals to free up natural gas locked into shale deep underground.
3. The Vermont Law School says new federal rules on hydraulic fracturing or fracking on public lands in among eight likely actions expected to take place in 2012.
The law school also said to look for the release of initial results from the U.S. Environmental Protection Agency's look at fracking and ground water. It also predicted a rising tide of class-action lawsuits against drillers for fracking. State moratoriums are also possible.
