Dccember 7 2011 U S Army Corps of Engineers Regulatory Field Office 3331 Heritage Trade Drive Suite 105 Wake Forest NC 27587 ATTN Mr Monte Matthews NCDOT Coordinator Dear Sir EUGENE A CONTI JR SECRETARY Subject Application Update for an Individual Section 404 and Section 401 Water Quality Certification for SR 1001 (Connelly Springs Road) from US 321A (Norwood Street) to SR 1712 (Starcross Road) in Caldwell County Federal Aid Project No MA STP 7533(2) Division 11 WBS 34783 1 1 TIP No U 2211B Reference Application for an Individual Section 404 Permit and Section 401 Water Quality Certification dated August 24 2011 The North Carolina Department of Transportation ( NCDOT) proposes to extend SR 1001 (Connelly Springs Road) on new location with the realignment of SR 1178 (Hibriten Drive) in Lenoir Caldwell County Since the original permit application was submitted on August 24 2011 there has been an additional stream discovered that was previously not identified as jurisdictional Also additional bank stabilization will be added to an existing permit site This application update provides updated impact numbers and permit site descriptions reflecting these changes at sites 2a 4 and 5 Please see the enclosed Revised Ecosystem Enhancement Program (EEP) mitigation acceptance letter and revised permit drawings for the above referenced project The enclosed permit drawings replace permit drawings 3 5 6 7 and 8 of 14 from the August application and include an additional drawing Sheet 14a of 14 Roadway design plan sheets 6 and 7 are also enclosed Summary of Jurisdictional Impacts In the August permit application it was stated that the project will permanently impact 0 24 acre of wetlands 1 252 linear feet of streams and temporarily impact 0 01 acre (73 linear feet) of streams Since MAILING ADDRLSS TELEPHONE 919 717 6100 LOCATION NC DEPARTMENT OF TRANSPORTATION FAX 919 212 5785 PROJECT DEVELOPMENTAND ENVIRONMENTAL ANALYSIS 1020 BIRCH RIDGE DRIVE 1598

streams and temporarily impact 0 01 acre (53 linear feet) of streams Summary of Mitigation Compensatory mitigation for 0 24 acre of wetland impacts will still be provided by debiting the Long Creek Mitigation Site in Mecklenburg County Previously it was stated that the EEP will provide compensatory mitigation for 1 252 linear feet of stream impacts (the previous EEP request was incorrectly submitted for all 1 252 feet of permanent impacts rather than the 964 linear feet at 2 1 to satisfy the USACE mitigation requirements) To account for the additional stream impacts the EEP will provide mitigation for the 1 261 linear feet of permanent stream impacts which require mitigation (see Table 1B) IMPACTS TO WATERS OF THE U S Impacts to wetlands have not changed since the August application Table 113 summarizes the updated impacts to jurisdictional water resources and replaces Table 113 in the August application Site numbers correspond with the permit (hydraulic) drawings included in this application The stream names correspond to the 2007 NEPA document A brief description of the updated impact sites will follow the table Table 113 — U -2211B Revised Stream Impacts (chanLyes are

(U )) 2 Mitigation for bank stabilization impacts required by DWQ— not required by USACE 3 UT2 was determined by the USACE in March 2008 to be an intermittent unimportant stream (not requiring mitigation from USAGE) Since that time DWQ has changed its policy regarding mitigating foi intermittent streams therefore it now requires mitigation from DWQ at a I 1 ratio 4 Values are based on rounding due to some of the individual impacts being <0 01 acre 5 Mitigation proposed by NCDOT (based on mitigation required by the USACE exceeding the amount required by DWQ) U 2211 B IP Application Update Page 2 of 4 Descriptions of Permit Sites 1 2 and 3 remain the same as they were written in the August 2011 permit application Since the August application a new permit site (2a) has been added additional impacts have been included within Site 4 and temporary impacts no longer occur at site 5 Permit Site 2a A new jurisdictional feature UT3 to Gunpowder Creek has been identified within the project footprint since the August 2011 permit application This channel begins at the outlet of an existing 24 corrugated metal pipe (CMP) under Hibriten Drive and is located dust east of wetland W1 All 297 linear feet of UT3 will be impacted by the proposed new interchange at US 321 as a result of roadway fill Permit Site 4 The existing 72 CMP approximately 40 in length that carries UT1 under Starcross Road (SR 1712) will be replaced with an 8 x 8 reinforced concrete box culvert (RCBC) This RCBC will be slightly longer (64 3 ) to accommodate the widened portion of Starcross Road but will provide better alignment for the stream than the existing CMP The pipe replacement will result in 42 linear feet of permanent impacts to UT1 Additionally there will be <0 01 acre (19 linear feet) of temporary impacts associated with culvert installation and 41 linear feet of bank stabilization impacts to UT1 at the inlet and outlet ends of the new culvert Previously the temporary impacts totaled 29 linear feet ( <0 01 acre) but 10 of these feet are now incorporated into the bank stabilization impacts described below A short section of UT1 between the inlet of the proposed culvert extension and the outlet of a pipe under a nearby driveway will now be stabilized and counted as a bank stabilization impact This will result in 61 additional feet of bank stabilization impacts to UTl for a total of 102 linear feet of bank stabilization at Site 4 There is potentially petroleum contaminated soil in the immediate vicinity of the stabilization of UT1 described above Therefore during construction this stream will be temporarily dewatered (using NCDOT s Best Management Practices for Construction and Maintenance Activities) during the placing of the rip rap bank protection to ensure that the stream does not receive contamination from the disturbance of the soils during bank stabilization Permit Site 5 The existing 24 CMP, approximately 36 in length that carries UT2 under Hibriten Drive will be removed and replaced with a 54 RCP to accommodate the widened roadway in this location A portion of the channel on the inlet side of the new pipe will be lined with rip rap for stabilization purposes This pipe replacement and upstream rip rap will result in 153 linear feet of permanent impacts to UT2 The previous <0 01 acre of temporary impact listed for this site at the outlet end of the pipe is now incorporated into the bank stabilization impacts at site 4 MITIGATION OPTIONS Compensation The NCDOT has avoided and minimized impacts to jurisdictional resources to the greatest extent practicable as described above This project will permanently impact 0 24 acre of wetlands 1 610 linear feet of streams and temporarily impact 0 01 acre (53 linear feet) of streams U 2211 B IP Application Update Page 3 of 4 Of the 1 610 linear feet of permanent stream impacts 1 261 linear feet are permanent impacts to a perennial stream 196 linear feet are bank stabilization impacts to this same perennial stream and 153 linear feet are permanent impacts to an intermittent unimportant stream Therefore all 1 610 linear feet of permanent stream impacts require mitigation by DWQ at a ratio of 1 1 A total of 1 261 linear feet of permanent stream impacts require mitigation by USACE at a ratio of 2 1 The USACE stream mitigation requirement is 2 522 ft (1 261 ft @ 2 1) The DWQ stream mitigation requirement is 1 610 ft (1 610 ft @ 1 1) Please reference Table 113 in this application update for further breakdown of impacts and mitigation requirements Therefore the NCDOT proposes to mitigate for the larger of these mitigation requirements 2 522 ft by utilizing the EEP (see attached updated acceptance letter) Mitigation for the 0 24 acre of wetland impacts will be still provided by debiting the Long Creek Mitigation Site at a ratio of 1 1 as described in the August application Thank you for your assistance with this project If you have any questions or need
