The Marcellus Drilling News last week reported that a federal rule change by the U.S. Department of Transporationcould slow down the shale drilling industry.
In June, the federal agency approved a new “rule clarification” that disallows truckers from subtracting down time as they wait for trucks to be loaded or unloaded when it comes to hauling water and sand for hydraulically fracturing or fracking oil and gas wells.
The rule clarification has been controversial and costly, according to the Marcellus Drilling News.
More than 60 Congressmen have sent a letter to Transportation Sec. LaHood requesting the rule clarification be reversed because it targets a particular industry: shale drilling.
