The language of Section 106 (any federal agency that may damage historic property, especially those listed on the National Register of Historic Places, must consider the effects on historic properties and "seek ways to avoid, minimize or mitigate" any adverse effects on historic property) seems to apply only to projects undertaken directly by a federal agency - NOT by private commercial entities.
Alternatively, Section 106, at least according to the quoted portion above, refers to federally funded or federally permitted projects. Fracking wells are never federally funded. As to permits, the hearings I've seen reported have all been under the aegis of Pennsylvania's Department of Environmental Protection, not the federal EPA.

"Under the federal code, the company was required to notify Army Corps of Engineers officials if it encountered archaeological finds. To prevent such delays, Mr. McHale said, an archaeologist under company contract checks whether proposed pipeline routes and project plans might disrupt any historic sites. If so, the company alters the routes to avoid them.
"When artifacts were found at a Blaine Township site where Mark West had proposed to create a wetlands, the company was required to preserve those areas to comply with the federal History Code.
"Mr. McHale and state officials met with Mr. Kotz in August 2009 to discuss historic preservation, and everything was amicable, he said. But Mr. Kotz said his suggestions were ignored.
"Mark West built a compressor station in Blaine on a site designated as historic, but Mr. McHale said the location of the archaeological resources wasn't clear and findings were deemed to be minimal, so the company went ahead with the project.

It is too bad the reporter was not thorough enough to give a specific cite/link to whatever part of the federal code is referred to. However, the code is described as putting the burden on the developer/driller to determine archaeological significance. And there are several references to drilling companies hiring their own archaeological/hired gun/experts to make that decision, i.e, cover their butts. "Hey, our expert said "locations weren't clear, and our expert deemed any findings "minimal"."
Another business friendly regulation trusting the fox to guard the hen house.
Drill first, argue points of law later.
