One of the biggest local impacts from gas drilling is large trucks in great numbers on country roads that were not built to withstand them. Predictably, the roads don't do well, with some being reduced to mud trails.
Damage is real, and inconvenience is inescapable. But the gas drilling industry pays for damage done. To date, the gas industry paid $500 million to repair roads just in Pennsylvania.
When repairing roads, the industry will sometimes improve them so that they can withstand heavy use by trucks. Yet, damage and the repair bills keep coming due. According to State Impact PA, the gas industry is currently repairing 400 miles of roads in three counties in Northeastern Pennsylvania.
