W &R submitted a NWP 39 PCN, dated 3/7/13, for the Mims Stormwater Control Project
via FedEx for delivery on March 11, 2013. We identified a typographic error in the
impact calculations on the Overall Plan and Index exhibit. Specifically, the Overall Plan
and Index Exhibit listed the total permanent stream impacts as 56 If, when the proposed
permanent stream impacts are actually 65 If Therefore, we are providing copies of the
revised Impact Plans for inclusion in the PCN submittal packet.
We apologize for any inconvenience and please free to call if you have questions or
require additional information.
Sincerely,
Troy Beasley
Environmental Scientist
