TROGDON, III SECRETARY Addendum to Revision Request for Section 404 Regional General Permit No. 31 and Section 401 General Water Quality Certification No. 3886 for the proposed Interstate 85 (I-85) Widening and Interchange Improvements from north of NC 73 (Davidson Highway / Exit 55) to north of SR 2180 (Lane Street/Exit 63), Cabarrus & Rowan Counties, Divisions 9 and 10. Federal Aid Project No. FANHIMF-085-2(61)55, TIP Project No. I-3802A. REFERENCE: 1) Revision Request for Section 404 Regional General Permit No. 31 and Section 401 General Water Quality Certification No. 3886, dated October 26, 2017. Dear Madam: Since the submittal of the above-referenced permit revision request by the N.C. Department of Transportation (NCDOT) on October 26, 2017, it has been determined that there are additional impacts associated with this project at Permit Site No. 18 that NCDOT would like to have included in the permit revision. Additionally, there was an error in the reporting of wetland excavation impacts at Permit Site No. 14 in the revision request. The impacts were accidentally double-reported, with <0.01 acres being added twice to the impact summary sheet. This error, due to rounding, accidentally added 0.02 acres of mitigable wetland impact to the project. This error has been corrected in the attached permit drawings and a revised mitigation summary is included below with the correct required wetland mitigation amount. In addition to this letter, please find enclosed revised Wetland and Stream Permit Drawing Sheet Nos. 61 — 64 and 126 — 128 of 128; and drawings depicting the approximate location of the crane mats to be used at Site 18. MailingAddress: Telephone: (919) 707-6000 Location: NC DEPARTMENT OF TRANSPORTATION F[iC: (919� 212-57H5 1 OZO BIRCH RIDGE DRNE EtJVIRONMENTAL ANALYSIS UNIT Customer Service: 1-877-368-4968 RnLEIGH NC 27610 1598 MAIL SERVICE CENTER Website.• www.ncdot.gov RnteiGH NC 27699-1598 Description of Changes at Site 18 Stream SE — Cold Water Creek In order to assist with demolition of the existing bridge, crane mats will be placed into Cold Water Creek, resulting in temporary surface water impacts. The crane mats are 4— foot wide by 1— foot thick oak timbers that will be placed in the stream bed by an excavator from the bank. Two parallel rows of mats will run 125 feet within the stream channel. The excavator will place the bucket on the furthest timber from the bank and elevate its tracks to load itself onto the closest timber. Once the front portion of the tracks are on the timber it will position itself on both timbers by rotating 90 degrees and placing the bucket once again on the crane mats. While on the crane mats, Type 2 fabric will be secured across the creek channel and under the excavator to catch any demoed debris. Once demolition is complete, the removal process of the crane mats will be in the reverse order as they were placed. By using the timber mats within the streambed, construction crews can minimize the amount of concrete material from bridge demolition to fall in Cold Water Creek. Not only will this help limit the amount of material loss, but also allow construction crews to reduce the demolition time to six days. Work would commence on a week when the weather forecast did not support any precipitation, and work nonstop continuous days until the two existing mid-bents are demolished. The placement of these mats will result in 125 linear feet (0.07 acres) of temporary surface water impacts. A portion of this impact overlaps with the bank stabilization impacts at this site, but is occurring in a portion of the channel that was not impacted by the bank stabilization. Revised Compensatory Miti�ation The addition of temporary impacts at Site 18 will not result in the addition of any mitigable stream impacts. Therefore, the mitigable stream impacts presented in the permit revision request dated October 26, 2017 are correct and unchanged by this letter (Table 1). However, due to the accidental double-reporting of wetland excavation impacts at Site 14 in the revision request, there is a change to the wetland mitigation required for the project. The double- reporting added an additional <0.01 acres of excavation to the site which, due to rounding, resulted in 0.02 acres of mitigable wetland impact being added to the project total. This increased the total mitigable wetland impact for the project to 0.36 acres. The accidentally-added <0.01 acres of wetland excavation has been removed from the site. The new total impact for this site is <0.01 acres. Due to rounding, this addition did not increase the total wetland impacts for the project. The total wetland impacts have been corrected to a total of 0.34 acres, which is what is currently permitted for the project. In summary, although there is a new excavation impact at Site 14, it does not change the overall permanent wetland impact or wetland mitigation required for the project. I-3802A Addendum to 2°d General Permit 31 Revision Request 2 Table 1. I-3802A Revised Impacts Requiring Mitigation Required NCDMS Mitigation Total NCDMS Mitigation Stream Impacts in Length (ft.) 3,0481 1,838 @ 2:1 1,210 @ 1:1 4,886 Riparian Wetland Impacts (ac.) 0.34 2:1 0.68 Of the 4,241 linear feet of permanent stream impact, 1,006 linear feet did not require mitigation from USACE since it was bank stabilization. An additional 187 linear feet at Site 19 did not require mitigation. A request is hereby made to the Department of the Army and N.C. Division of Water Resources to include the above information with the Permit Revision Request submitted by NCDOT on October 26, 2017. A copy of this addendum and its distribution list will be posted on the NCDOT website at https://connect.ncdot.�ov/resources/Environmental/Pa�es/default.aspx, under Quick Links> Permit Applications.
