Norwest’s environmental group was retained to coordinate a multi-year project to collect hydrology, geology, and other environmental resource data in the Powder River Basin of Montana. This was a 35,000-acre project involving the submission of an application to determine the presence of alluvial valley floors within the area of a proposed coal mine.
Norwest designed a program to collect data for the state of Montana to be able to determine if the study area met the state’s criteria for alluvial valley floors. The process began by conducting soils, vegetation, hydrology, hydrogeology, geomorphic, and geologic studies to assess the site characteristics. Additionally, color infra-red and LiDAR data were collected to assist in these evaluations. The data was analyzed to assess the study area characteristics for each of the criterion used by the state of Montana for alluvial valley floor determination.
Norwest met projected timelines and supported the project to produce a comprehensive application package that was well received by the client. Norwest was able to provide interdisciplinary support to compiling a comprehensive permit application that integrated large volumes of technical information.
