Here a collection of recent Ohio news items on Utica shale drilling:
1. A new report by the National Wildlife Federation says that Ohio and Michigan need to strengthen laws on hydraulic fracturing or fracking to protect streams, lakes and wildlife.
"Our analysis shows that Michigan and Ohio are doing some things right, but the states remain vulnerable to risks associated with fracking," said spokeswoman Sara Gosman.
Ohio has toughened its laws, but still needs to do more, she said.
You can read the report at www.nwf.org/greatlakes.
2. Spencer Hunt of the Columbus Dispatch reported that the state of Ohio is considering giving drillers access to water for fracking from state-owned reservoirs, lakes and streams.
The issue has been under discussion since at least April, according to state records.
How much the drillers might pay for water has not been determined.
Nine state parks and two state forests with lakes or central streams are located in a 16-county region of eastern Ohio where drilling interest is highest, Hunt reported.
The state is still attempting to determine how much mineral rights it owns on that land.
The Muskingum Watershed Conservancy District approved one water sale to a driller from Clendening Reservoir. It later terminated such sales until the issue can be investigated more.
