Stream impact revisions occur at Sites 4, 12, 17, and 17A. Descriptions of the changes at each site are below. Please also see Table 1, which has been revised to reflect these modifications. Revised Sites, sub-totals, and totals are in bold. Permit Site 4(Permit Drawing 30 of 91) at 36+20 -SR2- Lt • The contractor has installed the 48-inch pipe structure and rip rap bank stabilization following the most recently approved permit drawing at this site. Recent rain events have resulted in significant scour and failure of streambanks immediately upstream of the rip rap that has been installed by the contractor. The Departinent proposes to install additional Class II rip rap on the stream banks that would allow for the permanent stabilization within the project limits. • This design change will result in an increase in temporary stream impacts of 5 linear feet and an increase in permanent bank stabilization impacis of 105 linear feet. Permit Site 12 (Permit Drawing 53 of 91 and 55 of 91) at 25+50 -Y2- Rt Installation of the complete hydraulic system will result in an increase in runoff velocity during heavy rain events at this location. The Department has evaluated the existing stream channel and determined thai the channel should be lined with a rip rap-lined 3 foot-base ditch to provide long- term stability. This design change will result in a decrease in temporary stream impacts of 60 linear feet, an increase of permanent stream loss impacts of 84 linear feet, and a decrease in permanent bank stabilization impacts of 24 linear feet. Permit Site 17 (Permit Drawing 60 of 91) at 133+15 -L- Lt and Permit Site 17A (Permit Drawing 60 of 91) at 133+26 -L- Lt • The contractor is currently installing the culvert at this location. The Department evaluated the existing stream channel at the culvert outlet and determined that the previously-permitted permanent rip rap bank stabilization at Permit Site 17 and previously-permitted temporary stream impacts at Permit Site 17A will not provide appropriate long-term stabiliiy. Additional Class II rip rap bank stabilization is proposed at the culvert outlet. • At Permit Site 17, this design change will result in an increase in temporary stream impacts of 5 linear feet and an increase in permanent bank stabilization impacts of 55 linear feet. • At Permit Site 17A, this design change will result in a decrease in temporary stream impacts of l 9 linear feet and an increase in permanent bank stabilization impacts of 25 linear feet.

ZPer USACE, no compensatory mitigation is required far permanent impacts (including bank stabilization) to USACE-regulated intermittent streams associated with this project. 3 Per the NCDWQ Public Memorandum dated August 14, 2009, any NCDOT project within the Merger Ol process that has reached CP 4A prior to the effective date of October 16, 2009 is not subject to the NCDWR intermittent Stream Mirigation Policy. This project reached CP 4A on December 13, 2007 and is not subject to this policy. Therefore, no compensatory mitigarion for permanent impacts along intermittent streams is required by NCDWR for this project. alsolated streams are not regulated by USACE. SPer USACE, bank stabilization impacts do not require compensatory mitigation. 6Although this Site does not individually exceed the 150 linear foot threshold set by NCDWR for requiring compensatory mitigation, when combined with other Sites along the same stream, the cumulative impact to the stream exceeds that threshold. Wetlands A new wetland impact site has been added to the project. Per USACE request, proposed impacts to this site are included with this modification request. This new site, Site No. 33, occurs within the Neuse River Basin (HUC 03020201). A description of this addition is below. Please also see Table 2, which has been revised to reflect this addition. Revised Sites, sub-totals, and totals are in bold. Permit Site 33 ABF Freight Corporation, Horvath Associates (representing ABF Freight), and NCDOT have been working on a plan to remediate the loss of property resulting from TIP Project No. U-0071 on the ABF Freight parcel located at 208 Muldee Street in Durham, North Carolina. The reinediation plan consists of replacing the lost truck terminal parking spaces and necessary truck turning movement area (which were lost due to NCDOT ROW encroachment) on an adjacent property. This property will remain outside of the limits of the NCDOT ROW upon completion of U-0071. Within the proposed limits of disturbance for the proposed wark, there is a small portion of a jurisdictional U-0071 Permit Modification Application 0 wetland (Wetland WA) that needs to be iinpacted in order for the replacement parldng areas to reasonably function for the intended uses. Additionally, for proper truck movements to occur and for the replacement area to be used as needed by the ABF Freight Corporation, the disturbance of this wetland area is unavoidable. A large portion of this wetland will remain undisturbed and this request is only for disturbance of the area necessary for the site to function properly. • This design addition will result in 0.09 ac. of permanent fill at Site No. 33.

Riparian Buffers All revisions occur within the Neuse River Basin (HUC 03020201). Riparian buffer impact revisions occur at Sites 4 and 17. Descriptions of the changes at each site are below. Please also see Table 3, wbich has been revised to reflect these modifications. Revisions are in bold.

Revised sub-totals and totals are in bold. Mitigation for the revised totals will be provided by DMS. Please see the attached DMS Mitigation Acceptance Letter. Stream Irrzpacts A total of 5,8�47 linear feet of permanent warm water stream impacts will occur within the Neuse Basin. This is an increase of 245 linear feet compared to the 5,602 linear feet that was reported in the 2"a permit modification application. A total of 1,4141inear feet of permanent warm water stream impacts will require compensatory mitigation per USACE at a 2:1 ratio. This is unchanged since the 2°a permit inodification. The amount of permanent stream impacts requiring compensatory mitigation per NCDWR increased since the 2"d permit modification application from 1,9541inear feet to 2,0091inear feet; these impacts will be mitigated for at a 1:1 ratio. Wetland Impacts A total of 0.55 acres of permanent wetland impacts will occur within the Neuse Basin. Of that 0.55 acres, 0.27 acres are isolated and do not require mitigation. The remaining 0.28 acres will require compensatory mitigation per USACE at a 2:1 ratio. This is an increase of 0.09 acres due to the inclusion of Site 33. This is the 15S modification to wetland impacts since the original permit. Riparian Buffer Impacts A total of 353,760 square feet of mitigable Zone 1 Riparian Buffer impacts and 241,972 square feet of mitigable Zone 2 Riparian Buffer impacts will occur within the Neuse Basin. This is an increase of 4,478 square feet of mitigable Zone 1 buffer impacts and 671 square feet of mitigable Zone 2 buffer impacts when compared to previously-permitted amounts (most recently modified by the 1s` permit modification). Zone 1 impacts will be mitigated for at a 3:1 ratio, while Zone 2 impacts will be mitigated for at a 1.5:1 ratio. Table 4.

Based on the information supplied by you on May 3, 2016, the additional impacts are located in CU 03020201 of the Neuse River Basin in the Central Piedmont (CP) Eco-Region, and are as follows: Table 1— Additional Neuse 03020201 CP Impacts (feet/acres) pacts (feet / acres) Stream Cold Cool Warm 0 0 58.0 Wetlands Riparian Non- Coastal Riparian Marsh 0.09 Buffer (Sq. Ft.) Zone 1 Zone 2 (3:1) (1.5:1) 4,478.0 671.0 All buffer mitigation requests and approvals are administrated through the Riparian Restoration Buffer Fund. The NCDOT will be responsible to ensure that appropriate compensation for the buffer mitigation will be provided in the agreed upon method of fund transfer. Upon receipt of the NCDWR's Buffer Authorization Certification, DMS will transfer funds from the NCDOT 2984 I'und into the Riparian Restoration Buffer Fund. Upon completion of transfer payxnent, NCDOT will have completed its addition riparian buffer mitigation responsibility for TIl' Number U-0071. These additional impacts and associated mitigation needs were not projected by the NCDOT in the 2016 impact data. DMS is currently providing stream and riparian wetland mitigation for the impacts associated with this project located in cataloging unit 03030002 of the Cape Fear River basin and cataloging unit 03020201 of the Neuse River basin as required by the 404 and 401 permits that were issued in 2014 and 2015, as shown in the below table (in mitigation credits): State of North Carolina � Environmental Quality ', Mitigation Services 1652 Mail Service Center � Raleigh, NC 27699-1652 � 217 W.

See permit application for details. DMS will provide the amount of mitigation as determined by the regulatory agencies. DMS has previously made debits for the stream and riparian wetland mitigation requirements to mitigation sites available in the cataloging units based on the amounts required in the 404 and 401 permits issued in 2014 and 2015. NCDOT has made payment for all riparian buffer mitigation as required by DWR. Upon issuance of the pernut modiiications for the project, DMS will make appropriate adjustments to the existing mitigation debits.
