Rover Pipeline is asking the Federal Energy Regulatory Commission for approval to resume horizontal directional drilling (HDD) at nine sites in northern Ohio, Kallanish Energy reports.
The company, in a series of filings, said it has incorporated recommendations from third-party consultant J.D. Hair & Associates, to improve safety and avoid leak problems when drilling under highways and streams.
Rover Pipeline said it will be adding downhole annular pressure tools in all phases of HDD, will provide hydrofracture analysis for all remaining HDDs, will give FERC the names and qualifications of all HDD inspectors, will hire drilling fluid specialists and will file with FERC a list of non-toxic HDD additives that may be used.
The company said it was confident it was addressing all concerns raised in an Aug. 22 filing by the Ohio Environmental Protection Agency.
Rover Pipeline urged FERC to approve HDD drilling as soon as possible.
The two sides have been battling for months over HDD leaks along the route of the pipeline being developed by Dallas-based Energy Transfer Partners. FERC had halted the remaining HDD drilling because of the problems.
Service has just started on 213 miles of the mainline and two laterals. Work is continuing on additional legs of the pipeline.
The 711-mile twin pipeline will carry natural gas from the Marcellus and Utica shales to the Midwest, Canada and the Gulf Coast. The $4.2 billion pipeline will move up to 3.25 billion cubic feet per day.
