Total Wetland Impacts: 2h. Comments: See attached chart. The permanent wetland impacts account for a 10 foot maintenance corridor to be permanently maintained upon completion of the project. The remaining 10-20 feet of permanent/temporary easement will be allowed to re-establish upon completion of construction. 3.

Total stream and tributary impacts 3i. Comments: See attached chart Total stream impacts is 0 (zero) due to each impact being a temporary impact for construction. Upon completion of construction, all stream crossings will be returned to pre-existing grade and conditions, with no permanent stream crossings. Page 4 of 10 PCN Form — Version 1.4 January 2009 4. Open Water Impacts N/A If there are proposed impacts to lakes, ponds, estuaries, tributaries, sounds, the Atlantic Ocean, or any other open water of the U.S. then indivi ually list all open water impacts below. 4a.

Total Buffer Impacts: 16,673 15,224 6i. Comments: Page 5 of 10 D. Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Where it is feasible, the new installations are designed to keep the stream, buffer, and wetlands crossings as close to 90 degrees as possible. The sewer on the Bartlett Mills property is designed and to be installed in an existing access driveway for residents on the north side of the railroad tracks. This area is already cleared and maintained. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Proper erosion control techniques will be used throughout the construction process, including the use of silt fence, silt fence outlets, properly designed and installed construction entrances, tree protection fencing, and rock check dams. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State? X❑ Yes ❑ No 2b. If yes, mitigation is required by (check all that apply): ❑X DWQX❑ Corps 2c. If yes, which mitigation option will be used for this project? ❑Q Mitigation bank ❑X Payment to in -lieu fee program ❑ Permittee Responsible Mitigation 3. Complete if Using a Mitigation Bank 3a. Name of Mitigation Bank: Resource Environmental Solutions, LLC 3b. Credits Purchased (attach receipt and letter) Type: Riparian buffer Type: Choose one Type: Choose one Quantity: 24,981 Quantity: Quantity: 3c. Comments: We will not authorize purchase of credits until DWQ and USACE has approved this application. 4. Complete if Making a Payment to In -lieu Fee Program 4a. Approval letter from in -lieu fee program is attached.X❑ Yes 4b. Stream mitigation requested: linear feet 4c. If using stream mitigation, stream temperature: Choose one 4d. Buffer mitigation requested (DWQ only): square feet 4e. Riparian wetland mitigation requested: .205 acres 4f. Non -riparian wetland mitigation requested: acres 4g. Coastal (tidal) wetland mitigation requested: acres 4h. Comments: We will not authorize purchase of credits until DWQ and USACE has approved this application. 5. Complete if Using a Permittee Responsible Mitigation Plan 5a. If using a permittee responsible mitigation plan, provide a description of the proposed mitigation plan. Page 6 of 10 PCN Form — Version 1.4 January 2009 6. Buffer Mitigation (State Regulated Riparian Buffer Rules) — required by DWQ 6a. Will the project result in an impact within a protected riparian buffer that requires Yes ❑ No buffer mitigation? 6b. If yes, then identify the square feet of impact to each zone of the riparian buffer that requires mitigation. Calculate the amount of mitigation required. 6c. 6d. 6e. Zone Reason for impact Total impact Multiplier Required mitigation (square feet) (square feet) Gravity Sewer Zone 1 8,327 3 (2 for Catawba) 24,981 Zone 2 Gravity Sewer 1.5 6f. Total buffer mitigation required: 24,981 6g. If buffer mitigation is required, discuss what type of mitigation is proposed (e.g., payment to private mitigation bank, permittee responsible riparian buffer restoration, payment into an approved in -lieu fee fund).
