Debit $240.00 from WBS Element 38868.1.1 References:R-3601 404/401/CAMA permit application dated April 26, 2013 R-3601 Nationwide Permit 23and 5,issued August 19, 2013 (SAW-2007- 03461-010) R-3601 Major CAMA permit, issuedAugust 2, 2013 (#89-13) R-3601 401 Water Quality Certification, issuedMay 16, 2013 (DWR# 13- 0472) The purpose of this letter is to request modification of the issued permits on this project to account for design changes and approved moratorium in-water work methods. Please find enclosedrevised permit drawings, sturgeon concurrence letter from theNational Marine Fisheries Service, and agency correspondence regarding construction methods for the above referenced project. Please replace permit drawings from the original submittal with the full set included with this modification request. As you are aware, the North Carolina Department of Transportation (NCDOT) proposesto widen US 17-74-76/NC 133 from the NC 133/SR 1472 Interchange to the US 421/NC 133 Interchangeby adding one auxiliary lane in each direction.

EBSITEWWWNCDOTORG 1548MSCR,NC 27610 AIL ERVICE ENTERALEIGH RNC 27699-1548 ALEIGH replacementof two bridges over the Brunswick River with one bridge carrying both travel directions. Additionally, the northbound bridge over Alligator Creek will be replaced and the southbound structure will be widened. To further alleviate congestion problems, a second auxiliary lane in the northbounddirectionwill be added. There will be 0.41acre of permanent impacts to riparian wetlands resulting from fill, excavation, and mechanized clearing resulting from project construction, of which 0.03acre are impacts to CAMA wetlands. This is a decrease from the previous permit which allowed for 0.44 acre of permanent impacts to wetlands of which 0.04 were impacts to CAMA wetlands. A total of 105linear feetof permanent stream impacts are also anticipated; this is a decrease from the 185 linear feet that were previously permitted.A revised EEP acceptance letter showing the decrease in impacts will be forwarded to you upon receipt. The permanent impact area due to bridge bents will be 0.03 acrewhich isa0.01 acreincrease from the previous permit. The design bridges will have fewer columns than previously permitted however the diameter is greater. This change was necessary in order to construct the structures and comply with the in-water work moratorium.Temporary work bridges will also be necessary to construct and improve bridges on this project. The existing clearances will be maintained on both the Alligator and Brunswick Rivers. A primary nursery area in-water work moratorium will be observed from January 1 to June 30 for Alligator Creek and from January 1 to September 30 for the Brunswick River. Limited in- water construction methods to be used during the in-water moratorium include working inside of casings, static pile extraction, spudding associated withbarges, removal of piles using a vibratory hammer, and installation of casings using the screwing in method (see attached memo and correspondence). Regulatory Approvals CAMA: NCDOTrequests that the Coastal Area Management Act (CAMA) Major Development permit (#89-13)issued on August 2, 2013be modified to account for adecrease in impactsand change in approved in-water work methods during the moratorium asnoted above. Section 404 Permit:All aspects of this project are being processed by the Federal Highway Administration as a “Categorical Exclusion” in accordance with 23 CFR 771.115(b). The NCDOT requests that these activities be re-issued under the existing Nationwide Permit 23 (refer to NWP 23 issued on August 19, 2013 SAW-2007-03641-010). Section 401 Permit: We anticipate 401 General Certification number 3891will apply to this projectas it was previously permitted (refer to 401 Water Quality Certification issued on May 16, 2013 DWQ#: 13-0472).All general conditions of the Water Quality Certification will continue tobe met. NCDOT is providing this application to the NCDWR for their review and approval. Memo To:AmyJamesFrom:MelissaRuiz NCDOT,NaturalEnvironmentSection801JonesFranklinRd.
