CLEVELAND (AP) — Environmental groups have asked an Ohio appeals court to revoke drilling permits granted
by a state agency for construction of massive underground salt caverns to store natural gas liquids
along the Ohio River, according to a lawsuit.
The complaint filed Thursday with the 10th District Court of Appeals in Columbus accuses the Ohio
Department of Natural Resources of not following its own rules by failing to require public notice of
company drilling applications, create draft copies of the permits or allow for a public comment period
before granting permits July 20.
The lawsuit asks the appeals court to order ODNR to restart the application process and follow its rules.
ODNR spokesperson Stephanie O’Grady said the department does not comment on pending litigation.
The caverns will be created by injecting millions of gallons of fresh water underground into an
underground salt formation in Ohio’s Monroe County. After construction, Powhatan Salt Company will turn
the project over to Denver-based based company Mountaineer NGL Storage to store ethane, propane and
butane, which are byproducts of natural gas drilling.
Salt solution created during construction would be transported by a pipeline beneath the Ohio River to an
alkaline plant in West Virginia.
Mountaineer NGL Storage is finalizing a deal with a U.S. subsidiary of a Thailand-based company, PTT
Global Chemical America, to provide ethane storage for a proposed multi-billion dollar petrochemical
plant that would produce plastic pellets in nearby Belmont County.
Whether the petrochemical plant will be built is uncertain. PTT Global’s partner, a U.S. subsidiary of
South Korea’s Daelim Industrial Co., quit the project in mid-July. A long-delayed decision on whether
PTT will move forward with a new partner is expected sometime next year.
The Ohio lawsuit was filed on behalf of individuals by Concerned Ohio River Residents, FreshWater
Accountability Project, Buckeye Environmental Network, Ohio Valley Environmental Coalition and Sierra
The complaint says construction and operation of the caverns could lead to spills that would harm private
and public water supplies, become a hazard for "potential explosiveness" after natural gas
liquids are stored, and would create an eyesore along the Ohio River.
