Tectonic performed general NEPA analysis tasks commonly associated with the level of analysis commensurate with and prior to the generation of a Categorical Exclusion associated with small to moderate scale operations and maintenance projects associated with high-voltage transmission systems. This included specialized surveys and/or monitoring.

The NEPA review included classification of the required level of review along with preparation of an evaluation of existing and future conditions associated with the proposed construction activities related to geology and soils, air quality, water quality, floodplains, wetlands, vegetation and wildlife, historic and cultural resources, and other applicable topics. Upon final review and conclusions of consultations as needed, the projects were documented and submitted for SWPA’s review utilizing the SWPA’s Categorical Determination, Categorical Justification and NEPA Checklist Form (SWPA F 450.4).

Section 106 Consultation letters were prepared and submitted to tribes, SHPO and other resource agencies and sometimes required the initiation of archeological surveys or monitoring special studies, analysis, assessments or permits applications identified after the preliminary review or consultation with the tribes, SHPOs, US Fish and Wildlife office, or other agencies. Tectonic provided archeological surveys and monitoring, and/or surveys or monitoring associated with project impacts regarding Section 7 Endangered Species Act (ESA) and federally listed Threatened or Endangered Species on an as-needed basis.
