Federal Proximity Factor Tool – Out of Basin Compensatory Mitigation for U.S. Army Corps of Engineers (USACE)

What is the Proximity Factor Tool?

Conditions for Using Out-of-Service Area Mitigation Banks

To utilize mitigation credits from banks outside their service area, the following criteria must be met:

  1. No Local Alternatives: Federal credits must be unavailable within the impact area’s basin or HUC.
  2. MBI Language: The Mitigation Banking Instrument (MBI) should include language permitting the use of credits for impacts outside the designated service area. This ensures regulatory compliance.

 

Case-by-Case Approval

Each instance of using out-of-service area credits requires approval from the relevant regulatory agencies.

Benefits of Using the Proximity Factor Tool

  • Expanded Options: Provides access to mitigation credits when local options are unavailable.
  • Regulatory Compliance: Ensures projects meet federal environmental regulations, preventing delays.
  • Ecological Benefits: Allows for effective mitigation by utilizing high-quality mitigation banks, regardless of their proximity to the impact area.

How to Proceed

  1. Identify Potential Mitigation Banks: Use resources like the Regulatory In-lieu Fee and Banking Information Tracking System (RIBITS) to find suitable banks.
  2. Review MBI Terms: Verify that the selected bank’s MBI includes provisions for out-of-service area mitigation.
  3. Coordinate with Regulatory Agencies: Engage with the USACE and EPA early in the planning process to obtain necessary approvals.

How Does the Proximity Factor Tool Work?

The Proximity Factor Tool determines the number of mitigation credits needed when a project impacts areas outside a mitigation bank’s service area. Here’s a concise breakdown:

General Considerations

  • The tool aligns with 33 CFR 332 regulations, ensuring compliance with federal guidelines.
  • The Corps evaluates the most environmentally preferable option for each project, applying the proximity factor on a case-by-case basis.
