Legislative MandateEnergy Policy and Conservation Act (EPCA) of
2000, Sec. 604
As amended by the Energy Policy Act of 2005, Sec. 347
Requires Interior (lead delegated to BLM), to consult with Agriculture (USFS) and Energy, to conduct an inventory of onshore Federal lands identifying the USGS estimate of the oil and gas resources and any “restrictions or impediments” (constraints) to their development.

Data Collection Challenges
• DOD Confidentiality Agreements• Sensitive Wildlife and Cultural Resources
Data• Lack of GIS Data in Eastern Basins• Lack of Staff/Higher Priority Projects• Fragmented Leasing Decisions• Florida Hurricanes

Conclusion• EPCA Phase II inventoried 99 million acres of
Federal land• Just over ½ of the oil resources are inaccessible• More than ¼ of the natural gas resources are
inaccessible• We couldn’t have done this without GIS!
