Chatham Park Investors LLC Section 4.5 Gravity Sewer 105 Weston Estates Way Cary, North Carolina 27513 M&C Project # 01561-0028 March 2024 Prepared by: Vv MCIM&CREED LNGINEERS SURVEYORS PLANNERS Wesley Hutchins, PE McKim & Creed, Inc. 4300 Edwards Mill Road, Suite 200 Raleigh, NC 27612 P:919-233-8091 DESIGN NARRATIVE 1.0 PROJECT DESCRIPTION A permit application package was previously submitted to NCDEQ for approval, at which time the Section 4.5 Gravity Sewer project was assigned a permit number but did not undergo the review process. Per NCDEQ a new permit application package is being submitted and a new permit number should be generated. The Section 4.5 Gravity Sewer project installs approximately 180 linear feet (LF) of 18-inch ductile iron (DI) sanitary sewer pipe, 130 LF of 18-inch PVC sanitary sewer pipe, 610 LF of 16- inch DI sanitary sewer pipe, 1,100 LF of 15-inch PVC sanitary sewer pipe, 800 LF of 8-inch DI sanitary sewer pipe and 930 LF of 8-inch PVC sanitary sewer pipe. The proposed gravity sanitary sewer outfall is a new gravity outfall installed for future development consisting of primarily single family residential homes. The site is located south of Moncure Pittsboro Rd and east of US 87 S. The total project has approximately 3.13 acres of disturbed area. 2.0 EXISTING SYSTEM The proposed gravity sanitary sewer will tie-in to the proposed wet well at Chatham Park South Pump Station No. 2. This downstream receiving sewer is permitted under WQ0043594. The Town of Pittsboro's existing WWTP will be converted to a regional pump station (known as the Sanford Regional Pump Station) and a new force main to convey raw wastewater will be constructed to discharge flow to the City of Sanford's Big Buffalo Wastewater Reclamation Facility (NPDES Permit NC0024147). This regional pump station and force main project is in redesign by the City of Sanford with anticipated constructed beginning in Summer 2024; no further update is available at this time. No flow will be generated until all projects are online, certified, and operational. 3.0 PROPOSED ADDITIONS The proposed construction will add approximately 180 linear feet (LF) of 18-inch ductile iron (DI) sanitary sewer pipe, 130 LF of 18-inch PVC sanitary sewer pipe, 610 LF of 16-inch DI sanitary sewer pipe, 1,100 LF of 15-inch PVC sanitary sewer pipe, 800 LF of 8-inch DI sanitary sewer pipe and 930 LF of 8-inch PVC sanitary sewer pipe and sixteen (16) sanitary sewer manholes. The proposed sanitary sewer is a new gravity outfall installed for future development that extends to a future sanitary sewer wet well and has been sized accordingly per NCDEQ's adjusted daily sewer flow rate approval dated January 2019. The future development that will contribute flow to the proposed gravity sewer system will consist of primarily single-family residential areas as well as an amenity center and a park. The project does not include the permitting of new sanitary sewer flows as no flow -generating development will occur directly related to this project. Other consultants will provide permits for the new flows in future projects for the development through submittal of separate Fast Track Sanitary Sewer Permit applications for each portion of the upstream infrastructure.

MEMORANDUM To: Wesley Hutchins - McKim & Creed CC: Robbie Oldham - WithersRavenel From: Rick Trone Date: 11/29/2022 Project: Chatham Park South Village - Section 4.5 Gravity Sewer Subject: 404/401/Riparian Buffer Permitting - Non -Notifying Authorization This memorandum is in reference the USACE 404 and NCDWR 401/Riparian Buffer permitting requirements for this installation of gravity sewer line via open trench construction. The proposed alignment will result in perpendicular crossings of Stream 149, Stream 147, and Stream 54 as well as their associated riparian buffers, which are subject to Town of Pittsboro Riparian Buffers. USACE 404 Approval The proposed gravity sewer line is eligible for 404 authorization under the USACE Nationwide Permit 58 (NWP 58) for Utility Line Activities (see attached). Per the conditions requiring notification under NWP 58, submittal of a pre -construction notification (PCN) to the USACE prior to commencing the activity is required if: 1) A section 10 permit is required - Not applicable. There are no Section 10 waters within the review area. 2) The discharge will result in the loss of greater than 1/10-acre of waters of the United States - The proposed installation of the sewer line will be conducted via open trench methods. All proposed stream impacts for installation of the sewer line, including open cutting of the streams and construction of temporary coffer dams for bypass flow and dewatering, will result in temporary stream impacts, which are not considered a loss of waters of the US. Upon completion of construction, the temporarily impacted streams (bed and bank) will be restored to pre -construction conditions (grades/elevation) and stabilized with biodegradable matting (no riprap or hard structures). There are no proposed permanent impacts. Therefore, the proposed project will not result in a "loss" of waters of the US. The proposed gravity sewer line construction does not meet the NWP 58 conditions requiring submittal of a PCN. The proposed project qualifies for a non -notifying NWP 58 and submittal of a PCN to, or receipt of written authorization from the USACE is not required. NCDWR 401 Approval The proposed water line construction is eligible for 401 authorization under NCDWR Water Quality General Certification No. 4276 (WQC 4276) for Utility Lines. Per general conditions of WQC 4276, written authorization from NCDWR is required if the activity meets any one of the following thresholds or circumstances: 115 MacKenan Drive I Cary, NC 27511 t: 919.469.3340 f: 919.467.6008 1 www.withersravenel.com I License No. F-1479 Asheville I Cary I Charlotte Greensboro I Lumberton I Pittsboro I Raleigh I Southern Pines I Wilmington :0 WithersRavene[ b) Total temporary impacts to streams greater than 500 feet within the entire utility project - The proposed project will result in less than 110 ft of cumulative temporary stream impacts for all three crossings. c) Anypermanent impacts to streams - All proposed stream impacts are temporary. There are no proposed permanent stream impacts. d) Total permanent impacts to wetlands or open waters equal to or greater than one -tenth (1/10) acre within the entire utility project - Not applicable. There are no proposed permanent impacts to wetlands or streams. e) Any stream restoration or stream relocation - Not applicable f) Any high -density project, as defined in 15A NCAC 02H .1003(3) and by the density thresholds specified in 15A NCAC 02H .1017, (which meets sub -conditions i, ii, iii, iv)- Not applicable. The proposed project is not a high -density project. g) Any permanent impacts to waters, or wetlands adjacent to water, designated as: ORW (including SAV), HQW (including PNA), SA, WS-1, WS-11 or North Carolina or National Wild and Scenic River - Not Applicable. The proposed stream crossings will occur within unnamed tributaries to Robeson Creek, which has a water quality classification of WS-IV;NSW,CA. h) Any permanent impacts to coastal wetlands or Unique Wetlands (UWL) - Not Applicable. j) Any impacts to subject water bodies and/or state regulated riparian buffers along subject water bodies in the Jordan Lake Basin - The proposed stream crossings will not occur in state -regulated riparian buffers. The proposed sewer line construction does not meet any conditions requiring written authorization from NCDWR, and therefore does not require submittal of a PCN to, nor receipt of written authorization from NCDWR. Based on the information provided above, the proposed temporary stream impacts do not require written authorization from the USACE nor NCDWR. Therefore, construction may begin at any time and coordination with the USACE nor NCDWR is not required prior to construction. Please feel free to contact me if you have any questions concerning the information provided in this memo. Additionally, please keep a copy of this memo in your project files for future reference.

EXCERTP FROM USACE NWP 58 Nationwide Permit 58 Utility Line Activities for Water and Other Substances Effective Date: March 15, 2021 / Expiration Date: March 14, 2026 Authorities: Sections 10 and 404 Activities required forthe construction, maintenance, repair, and removal of utility lines for water and other substances, excluding oil, natural gas, products derived from oil or natural gas, and electricity. Oil or natural gas pipeline activities or electric utility line and telecommunications activities may be authorized by NWPs 12 or 57, respectively. This NWP also authorizes associated utility line facilities in waters of the United States, provided the activity does not result in the loss of greater than 1/2-acre of waters of the United States for each single and complete project. Utility lines: This NWP authorizes discharges of dredged or fill material into waters of the United States and structures or work in navigable waters for crossings of those waters associated with the construction, maintenance, or repair of utility lines for water and other substances, including outfall and intake structures. There must be no change in pre -construction contours of waters of the United States. A "utility line" is defined as any pipe or pipeline for the transportation of any gaseous, liquid, liquescent, or slurry substance, forany purpose that is not oil, natural gas, or petrochemicals. Examples of activities authorized by this NWP include utility lines that convey water, sewage, stormwater, wastewater, brine, irrigation water, and industrial products that are not petrochemicals. The term "utility line" does not include activities that drain a water of the United States, such as drainage tile or french drains, but it does apply to pipes conveying drainage from another area. Material resulting from trench excavation may be temporarily sidecast into waters of the United States for no more than three months, provided the material is not placed in such a manner that it is dispersed by currents or other forces. The district engineer may extend the period of temporary side casting for no more than a total of 180 days, where appropriate. In wetlands, the top 6 to 12 inches of the trench should normally be backfilled with topsoil from the trench. The trench cannot be constructed or backfilled in such a manner as to drain waters of the United States (e.g., backfilling with extensive gravel layers, creating a french drain effect). Any exposed slopes and stream banks must be stabilized immediately upon completion of the utility line crossing of each waterbody. Utility line substations: This NWP authorizes the construction, maintenance, or expansion of substation facilities associated with a utility line in non -tidal waters of the United States, provided the activity, in combination with all other activities included in one single and complete project, does not result in the loss of greater than 1/2-acre of waters of the United States. This NWP does not authorize discharges of dredged or fill material into non -tidal wetlands adjacent to tidal waters of the United States to construct, maintain, or expand substation facilities. Foundations for above -ground utility lines: This NWP authorizes the construction or maintenance of foundations for above -ground utility lines in all waters of the United States, provided the foundations are the minimum size necessary. Access roads: This NWP authorizes the construction of access roads for the construction and maintenance of utility lines, including utility line substations, in non - tidal waters of the United States, provided the activity, in combination with all other activities included in one single and complete project, does not cause the loss of greater than 1/2-acre of non -tidal waters of the United States. This NWP does not authorize discharges of dredged or fill material into non -tidal wetlands adjacent to tidal waters for access roads. Access roads must be the minimum width necessary (see Note 2, below). Access roads must be constructed so that the length of the road minimizes any adverse effects on waters of the United States and must be as near as possible to pre - construction contours and elevations (e.g., at grade corduroy roads or geotexti le/g ravel roads). Access roads constructed above pre -construction contours and elevations in waters of the United States must be properly bridged or culverted to maintain surface f lows. This NWP may authorize utility lines in or affecting navigable waters of the United States even if there is no associated discharge of dredged or fill material (see 33 CFR part 322). Overhead utility lines constructed over section 10 waters and utility lines that are routed in or under section 10 waters without a discharge of dredged or fill material require a section 10 permit. This NWP authorizes, to the extent that Department of the Army authorization is required, temporary structures, fills, and work necessary forthe remediation of inadvertent returns of drilling fluids to waters of the United States through sub -soil fissures or fractures that might occur during horizontal directional drilling activities conducted for the purpose of installing or replacing utility lines. These remediation activities must be done as soon as practicable, to restore the affected waterbody. District engineers may add special conditions to this NWP to require a remediation plan for addressing inadvertent returns of drilling fluids to waters of the United States during horizontal directional drilling activities conducted for the purpose of installing or replacing utility lines. This NWP also authorizes temporary structures, fills, and work, including the use of temporary mats, necessary to conduct the utility line activity. Appropriate measures must be taken to maintain normal downstream flows and minimize flooding to the maximum extent practicable, when temporary structures, work, and discharges of dredged or fill material, including cofferdams, are necessary for construction activities, access fills, or dewatering of construction sites. Temporary fills must consist of materials, and be placed in a manner, that will not be eroded by expected high flows. After construction, temporary fills must be removed in their entirety and the affected areas returned to pre -construction elevations. The areas affected by temporary fills must be revegetated, as appropriate. 2 Notification: The permittee must submit a pre -construction notification to the district engineer prior to commencing the activity if: (1) a section 10 permit is required; or (2) the discharge will result in the loss of greater than 1/10-acre of waters of the United States. (See general condition 32.) (Authorities: Sections 10 and 404) Note 1: Where the utility line is constructed, installed, or maintained in navigable waters of the United States (i.e., section 10 waters) within the coastal United States, the Great Lakes, and United States territories, a copy of the NWP verification will be sent by the Corps to the National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), for charting the utility line to protect navigation. Note 2: For utility line activities crossing a single waterbody more than one time at separate and distant locations, or multiple waterbodies at separate and distant locations, each crossing is considered a single and complete project for purposes of NWP authorization. Utility line activities must comply with 33 CFR 330.6(d). Note 3: Access roads used for both construction and maintenance may be authorized, provided they meet the terms and conditions of this NWP. Access roads used solely for construction of the utility line must be removed upon completion of the work, in accordance with the requirements for temporary fills. Note 4: Pipes or pipelines used to transport gaseous, liquid, liquescent, or slurry substances over navigable waters of the United States are considered to be bridges, not utility lines, and may require a permit from the U.S. Coast Guard pursuant to the General Bridge Act of 1946. However, any discharges of dredged or fill material into waters of the United States associated with such pipelines will require a section 404 permit (see NWP 15). Note 5: This NWP authorizes utility line maintenance and repair activities that do not qualify for the Clean Water Act section 404(f) exemption for maintenance of currently serviceable fills or fill structures. Note 6: For activities that require pre -construction notification, the PCN must include any other NWP(s), regional general permit(s), or individual permit(s) used or intended to be used to authorize any part of the proposed project or any related activity, including other separate and distant crossings that require Department of the Army authorization but do not require pre -construction notification (see paragraph (b)(4) of general condition 32). The district engineer will evaluate the PCN in accordance with Section D, "District Engineer's Decision." The district engineer may require mitigation to ensure that the authorized activity results in no more than minimal individual and cumulative adverse environmental effects (see general condition 23). GENERAL CONDITIONS Note: To qualify for NWP authorization, the prospective permittee must comply with the following general conditions, as applicable, in addition to any regional or case -specific 3 conditions imposed by the division engineer or district engineer. Prospective permittees should contact the appropriate Corps district office to determine if regional conditions have been imposed on an NWP. Prospective permittees should also contact the appropriate Corps district office to determine the status of Clean Water Act Section 401 water quality certification and/or Coastal Zone Management Act consistency for an NWP. Every person who may wish to obtain permit authorization under one or more NWPs, or who is currently relying on an existing or prior permit authorization under one or more NWPs, has been and is on notice that all of the provisions of 33 CFR 330.1 through 330.6 apply to every NWP authorization. Note especially 33 CFR 330.5 relating to the modification, suspension, or revocation of any NWP authorization. 1. Navigation. (a) No activity may cause more than a minimal adverse effect on navigation. (b) Any safety lights and signals prescribed by the U.S. Coast Guard, through regulations or otherwise, must be installed and maintained at the permittee's expense on authorized facilities in navigable waters of the United States. (c) The permittee understands and agrees that, if future operations by the United States require the removal, relocation, or other alteration, of the structure or work herein authorized, or if, in the opinion of the Secretary of the Army or his or her authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters, the permittee will be required, upon due notice from the Corps of Engineers, to remove, relocate, or alter the structural work or obstructions caused thereby, without expense to the United States. No claim shall be made against the United States on account of any such removal or alteration. 2. Aquatic Life Movements. No activity may substantially disrupt the necessary life cycle movements of those species of aquatic life indigenous to the waterbody, including those species that normally migrate through the area, unless the activity's primary purpose is to impound water. All permanent and temporary crossings of waterbodies shall be suitably culverted, bridged, or otherwise designed and constructed to maintain low flows to sustain the movement of those aquatic species. If a bottomless culvert cannot be used, then the crossing should be designed and constructed to minimize adverse effects to aquatic life movements. 3. Spawning Areas. Activities in spawning areas during spawning seasons must be avoided to the maximum extent practicable. Activities that result in the physical destruction (e.g., through excavation, fill, or downstream smothering by substantial turbidity) of an important spawning area are not authorized. 4. Migratory Bird Breeding Areas. Activities in waters of the United States that serve as breeding areas for migratory birds must be avoided to the maximum extent practicable. ■■ WithersRavenel lipp Our People. Your Success.
