Dear Mr. Sahnow:
We are responding to your pre-construction notification (PCN), submitted to us on
August 6, 2026, for verification of authorization under a nationwide permit (NWP) for the
Sahnow Pond Bank Stabilization. The project site is located on Sahnow Pond at
approximately latitude 39.407777, longitude -107.167833, Carbondale, Garfield County,
Colorado.
Based on the information provided, the project involves the discharge of dredged or
fill material into aquatic resources and you are requesting verification of authorization
under Section 404 of the Clean Water Act for the project. The specific activity that
requires Corps’ authorization is the placement of 132 cubic yard of boulders and backfill
materials into Sahnow Pond for the construction of bank stabilization along 135’ linear
feet of pond bank by placing interlocking boulders (2.5–3' in diameter) in the pond to
construct a retaining wall along the affected reach and backfill the wall with cobble and
gravel material to armor the bank. The project will permanently impact approximately
0.02 acre of open water pond, as described in the referenced PCN.
We have determined that activities associated with the project are authorized by
2026 NWP 13 Bank Stabilization. A summary of this NWP and the applicable Regional
Conditions are available at https://www.usace.army.mil/Missions/Civil-
Works/Regulatory-Program-and-Permits/Nationwide-Permits/ and
https://www.spa.usace.army.mil/Missions/Regulatory-Program-and-Permits/NWP/,
respectively. Failure to comply with all terms and conditions of this NWP may result in the
suspension or revocation of this authorization. As required by General Condition 30, you
shall sign the enclosed Compliance Certification (Enclosure 1) and return it to this office
within 30 days after completion of the authorized work. For specific information regarding
compliance with water quality certification (WQC) requirements, please refer to
https://www.spa.usace.army.mil/Missions/Regulatory-Program-and-Permits/Water-
Quality-Certification/.
This permit verification is valid until March 15, 2031, unless the NWP is modified,
suspended, reissued, or revoked prior to that date. Continued confirmation that an activity
complies with the terms and conditions, and any changes to the NWP, is the responsibility
of the permittee. Activities that have commenced, or are under contract to commence, in
reliance on an NWP will remain authorized provided the activity is completed within 12
months of the date of the NWP’s expiration, modification, or revocation.
We would appreciate your feedback on this permit action including your interaction
with our staff or suggestions for improving our program. For more information about our
