NEPA Evaluations

The National Environmental Policy Act (NEPA) of 1969 requires that the effects on the environment be evaluated prior to the approval of any major federal actions (construction) or federal permitting. NEPA typically includes completion of Environmental Assessments (EAs), Environmental Impact Statements (EISs) and Categorical Exclusion (CE) documentation for projects receiving federal funding. It may also include site screening for a variety of cultural, environmental, and socio-economic issues.


PPM provides a wide range of NEPA related services to government and private industry where the environmental aspects of a federal undertaking must be considered. Our services are designed to help you establish a Finding of No Significant Impact (FONSI) or mitigate issues as effectively as possible. NEPA analysis services offered include:


  • Categorical Exclusions (CATEXs)
  • Environmental Assessments (EAs)
  • Environmental Impact Statements (EISs)
  • Findings of No Significant Impact (FONSIs)
  • Records of Decision (RODs)


PPM also has alliances with specialty firms (cultural resources, endangered species, etc.) who can assist with highly specialized aspects of NEPA evaluations.

Project Highlight

PPM was retained to conduct an Environmental Assessment (EA) of two prisons as part of a proposal to be submitted to the Department of Justice (DOJ) – Bureau of Prisons (BOP). The BOP was asking for proposals to convert existing prisons from housing local prisoners to housing federal prisoners. The proposal had to be submitted within a short time frame. As part of the project, PPM prepared Phase I Environmental Site Assessments (ESAs) and completed full NEPA evaluations for each facility. PPM conducted the Phase I ESA first and did not identify any major issues. During the EA evaluation, a wetland issue was identified. The issue was quickly resolved by permitting with the Corp of Engineers (COE). The NEPA evaluations were completed within the specified timeframe and met with all requirements of the DOJ – BOP.
