The BLM issued an administrative memorandum [text] in March 2010 restricting the scope of those exceptions, allowing exceptions under § 390 of the 2005 Act only where a site or operation is within close physical proximity to a previous one, where a site is subject to a National Environmental Policy Act (NEPA) [materials]-sanctioned land plan, and where the operator completes additional reporting requirements. The NFS followed suit with its own memo [text, PDF] to the same effect in June. The ruling removes the 2010 restrictions, reinstating the Bush administration-era regime of expedited oil and gas drilling provisions under which provides categorical exceptions for all oil and gas drilling operations on federal land where a minimal degree of environmental disturbance is expected or where wells are subsequently tapped after an impact survey was performed at the first drilling.
