Environmental Standard Operating Procedures

FTA's Office of Environmental Programs developed environmental standard operating procedures (SOPs) to provide additional direction and recommendations to FTA staff who manage the environmental review process. The environmental review process SOPs supplement existing resources, such as FTA environmental regulations and various guidance documents. While initially developed for FTA staff, sponsors of FTA-funded projects may also find these SOPs useful.

The SOPs are listed and can be accessed individually in the table below. The table also indicates each SOP’s applicability to categorical exclusions (CEs), environmental assessments (EAs), and environmental impact statements (EISs).
