Project Examples

Superfund – Two On-Going Cases in Pacific Northwest
(One since 2008, the other since 2014)

Working with the US Department of Justice, TGA is compiling, reviewing, analyzing, and reporting on the significance of our efforts in relation to the activities by the United States and other potentially responsible parties (PRPs) before, during and after WWII. We have created and continue to maintain a central forensic spatial database and routinely provide maps, tables, and narrative for the attorneys as well as environmental and historian reports/opinions.

Environmental Litigation – NuWest v. US, Idaho, 2011
CERCLA action to Recover Costs from the US Government

Core to TGA staff’s involvement was mapping post-remediation mine extents (four sites) in relation to US Forest Service and other agency permits and regulations. GPS data and photographs acquired during site visits were utilized as reference in establishing feature boundaries. GPS data collection was also a means to create new line features representing edges of waste areas and pits.

Environmental Litigation – McMillian v. US, Oklahoma, 2010
Determine Share of Oil Refinery Impact Based on Activity Footprint and Term

Visualization (View-Shed and Photo Simulations)
Mining Permit Application, Public Process, Outreach

TGA produced view-shed analyses from 7 significant vantage points to determine what mine activities could be seen in both maximum disturbance and reclaimed terrain conditions. These exhibits were instrumental in demonstrating changes based on engineering data and communicating the nature of the project to local agencies and public concerns.
