Pogo Gold Mine Project, Alaska (1998-Ongoing): From 1998 to 2003, 3PP completed preliminary and final jurisdictional wetland mapping, vegetation mapping, and HGM wetland classification, including field verification, for Pogo Mine including three access road alternatives (approximately 85,000 acres) for Teck, Inc. To facilitate this work, 3PP and Resource Data Inc. (RDI), a local database and geographic information system (GIS) firm, built a comprehensive environmental GIS which ultimately supported a successful EIS process, and facilitated project permitting needs in 2003. Approximately 800 jurisdictional determinations were made by 3PP during the 1998, 1999, 2000, and 2001 field seasons to support this project. Mapping was completed directly over color ortho-rectified digital aerial photography, using heads-up digitizing techniques and ArcView software. The average polygon size mapped was approximately 17 acres, although polygon sizes ranged from just over one acre to over 1,000 acres. Approximately 25 vegetation and cover classes were mapped. After a successful EIS process mine construction was completed. Once the project began production, 3PPI was asked to provide periodic support to Pogo’s environmental staff relating to snow surveys, fish tissue sampling, annual report reviews, and regulatory and technical training.
In 2011, current project owners Sumitomo Metal Mining Pogo LLC hired 3PPI, to update the original wetland mapping to support an expansion of the Drystack Tailings Facility within the current project footprint. A wetlands and vegetation map was produced, and a supplemental PJD report was compiled and submitted to the U.S. Army Corps of Engineers. 3PPI also supplied regulatory assistance resulting in a successful permitting process.
3PPI work on the Pogo project is based from our Fairbanks office, with support from other team members as needed.
