Amschler, NCDOT Regulatory Coardinator JAMES H. TROGDON, III SECRETARY Subject: Request for Modification Individual Section 404 Permit and Section 401 Water Quality Certification for the Central and South sections of the I-77 HOT Lanes Project, I-5405 and I-3311C. Reference: Individua1404 Permit SAW-2012-00156 issued January 28, 2016 for the Central Section and subsequent modifications issued for the North Section on May 20, 2016, and South Section on November 24, 2016. Individual 401 Water Quality Certification No. WQC004036 issued November 13, 2015 for the Central Section, and subsequent modifications issued for the North Section on February 15, 2016 and South Section on May 16, and June 28, 2016. Dear Madam: As the I-77 HOT Lane project construction is underway, a review of the drawings and revisions to project access have resulted in modifications in three areas, two permanent impact changes in the Central Section and one temporary impact change in the South Section. These changes result in a surplus of 6linear feet of permanent stream impact and request for 40 additional feet of temporary stream impact. The changes for the Central Section of I-77 are as follows: Site 6-C: 8' x 7' culvert extension to the median The original/ permitted impact from culvert extensions was 26 linear feet of permanent stream impact, 21 linear feet of stream embankment, and 42 feet of temporary stream impacts for de-watering and construction access. When looking closely at the drawings (magnified below), it is noted that the measurement of the extension was based on the "JS line" instead of the existing culvert. This discrepancy results in a 10 linear foot deficit of permanent stream impact (noted in green below). The impact summary table has been revised to reflect the increase from 26 to 36 linear feet of culvert extension.

Plans (below) now indicate that only 53 linear feet of ctitivert extension is required. Thi� change t-esults iu a suiplus of perrl�anent stream impact of 16 fcet.

The team requests an additiona1401inear feet of temporary access/dewatering impact for a total of 85 linear feet, which will allow them to construct the Irwin Creek culvert at a more productive and safer location and sequence. This will also facilitate faster construction of the culvert, and reduced temporary fills in Irwin Creek, resulting in less time/exposure to high flow events while under construction. Please find attached revised Sheet 12 of 35 displaying this modification. This change results in the addition of 40 linear feet of temporary access/ dewatering. The impact summary table has been revised to reflect the increase from 45 to 85 linear feet. Impact Summarv Permanent Stream Impact The deficit of l O linear feet of permanent stream impact at Site 6-C, and surplus of 161inear feet at Site 7-C result in a total of 6 feet of surplus of permanent stream impact for the project. This decreases: The total permanent stream impact for the Central Section from: 410 to 4041inear feet, The total mitigable stream impact for the Central Section from: 185 to 1791inear feet, The total mitigable stream impact in HUC 03050101 from: 212 to 2061inear feet, and The total project from 1,860 to 1,8541inear feet. Temporary Stream Impact Forty additional linear feet of temporary dewatering/ impact is needed at site 3C-S. This increases: The total temporary stream impact for the South Section of the project: from 2,328 to 2,368 1£, The total temporary stream impact in HUC 03050103 from 2,328 to 2,368 linear feet, and The total temporary stream impact for the entire project from 3,117 to 3,1571inear feet, and Please reference attached revised Impact Summary Tables. Due to the amount of project construction remaining, NCDOT requests to retain the surplus 6linear feet of stream mitigation. If no other modifications are required, NCDOT will reconcile this difference during the final inspection by the USACE and NCDWR. If you have any questions or need additional information, please contact Michael Turchy at either maturchy@ncdot.gov or (919) 707-6157.
