Junkin and Vietor, Thank you for your PCN and attached information, dated and received 12/11/2019, for the above referenced project. I have reviewed the information and need clarification before proceeding with verifying the use of Nationwide Permit 13 (http://saw-reg.usace.army. mil/NWP2017/2017NWPI3.pdf [saw-reg.usace.army. mill). Please submit the requested information below (via e-mail is fine) within 30 days of receipt of this Notification, otherwise we may deny verification of the use of the Nationwide Permit or consider your application withdrawn and close the file: 1. The purpose of the project as proposed is to protect/maintain an existing pipeline, rather than to control or prevent erosion. Otherwise, avoidance and minimization would point toward stabilizing the stream channel in place rather than relocation. As such the project is not a good fit for NWP 13. Rather, the project is a better fit to use NWP 39; 2. Please provide a profile view along the centerline of the proposed channel relocation; 3. Please note that, at such point that the a NWP verification is processed, Special Conditions would be included requiring photo monitoring for at least 3 years post construction.

Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The site is within the Cardinal Pipeline ROW. Erosive conditions have pushed the stream west causing an approximately 110 linear foot section of pipeline to be exposed. The gas mainline is currently maintaining the current stream alignment. 3b. List the total estimated acreage of all existing wetlands on the property: 0 acres -- Review area has been limited to the within and immediately adjacent to the ROW, and the site access. 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: The tributary is estimated to be 1,430 linear feet on the property — However, review area has been limited to the within and immediately adjacent to the ROW, and the site access. This estimated measurement is from aerial and GIS information 3d. Explain the purpose of the proposed project: To stabilize the erosive stream conditions and provide cover over the exposed pipeline. 3e. Describe the overall project in detail, including the type of equipment to be used: To stabilize the stream and protect the integrity of the pipeline, the proposed construction will realign the channel back to preexisting conditions prior to installation of the pipeline. The stream banks will be armored to maintain the channel and minimize erosive conditions. In addition, a grade controlling device will be constructed at the upstream limits and a 3 step pool drop structure will be constructed downstream at the ROW limits to maintain the stream invert and dissipate the water velocity. The step pool structure will create a natural riffle -pool scenario providing habitat to species. The upstream structure will be at an elevation of approximately 721'. The 3 step pool structure will constructed approximately 120 feet downstream. The top of the structure will be at approximately 720' and the drops will be 1 foot to tie the invert back to the existing stream invert. The pool will be approximately 1.5 FT deep and 15 FT in length. Armor Stone will be utilized for step pool and bank armoring construction. Armor Stone will be 500-2,000 Ibs in size. The step pool structures will be constructed to maintain a low flow channel, and restore the stream to pre-existing conditions when the gas mainline was installed. Excavated material will be used to fill the existing channel as shown on these plans and seeded with native grasses. Stream banks will be graded to a 2:1 slope. Access to the stream will be via an existing dirt road from the property 680 Waynick Road previously used for logging. No trees will be removed to construct the stream restoration and Armor Stone will be installed as it is delivered to avoid removing trees for a stockpile area. A 360C caterpillar excavator or similar will be used to construct the project. Page 3 of 12 PCN Form — Version 1.3 December 10, 2008 Version 4. Jurisdictional Determinations 4a.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Since the pipeline is an existing infrastructure, impacts could not be avoided. The current stream morphology is flowing directly over 110+/- linear feet of exposed pipeline. Impacts have been limited to the greatest extent practical to provide protection to the exposed pipeline. Step pools were limited in length without jeopardizing the goal of mimicking a natural riffle -pool scenario and tying the stream back to the existing invert and the project was designed around the existing tree line. b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The proposed stream restoration allowed for the erosive conditions to be stabilized, provide adequate coverage over the pipeline, and minimize future stream migration. The construction of the project will be limited to within and immediately adjacent to the ROW. Step pool structures will be constructed from within the proposed stream channel to avoid impacts to the tree canopy. In addition, materials will be used as delivered to the site to avoid additional impacts to stockpile materials onsite. 2.

One (1) natural gas pipelines run the length of the ROW and the ROW is routinely maintained. A Tributary to Haw River runs relatively south within and adjacent to the ROW to the confluence with another tributary. The stream has been migrating west within the ROW resulting in approximately 110 linear feet of pipeline exposed where the stream flows on and parallel to the pipeline. The stream migration has also caused erosive conditions with steep banks. The Gas Mainline is currently maintaining the current stream alignment.

Introduction The Site is located approximately 8.5 miles southwest of Reidsville in Rockingham County, North Carolina, on the Cardinal Gas Pipeline Right -Of -Way (ROW). One (1) natural gas pipelines run the length of the ROW and the ROW is routinely maintained. A Tributary to Haw River runs relatively south within and adjacent to the ROW to the confluence with another tributary. The stream has been migrating west within the ROW resulting in approximately 110 linear feet of pipeline exposed where the stream flows on and parallel to the pipeline. The stream migration has also caused erosive conditions with steep banks. The Gas Mainline is currently maintaining the current stream alignment. II. Description of Work The proposed construction will realign the channel back to preexisting conditions prior to installation of the pipeline, immediately adjacent to the ROW. The stream banks will be armored to maintain the realigned channel, minimize erosive conditions, and future stream migration. In addition, a grade controlling device will be constructed at the upstream limits and a 2 step pool drop structure will be constructed downstream at the ROW limits to maintain the stream invert and dissipate the water velocity. The step pool structure will create a natural riffle -pool scenario providing habitat to species. The pool will be approximately 1.5 FT deep and 15 FT in length. Armor Stone will be utilized for step pool and bank armoring construction. Armor Stone will be 500-2,000 lbs in size. Excavated material will be used to fill the existing channel as shown on these plans and seeded with native grasses. Stream banks will be graded to a 2:1 slope. Access to the stream will be via an existing dirt road from the property 680 Waynick Road previously used for logging. Construction will avoid large trees to the greatest extent practical to construct the stream restoration and Armor Stone will be installed as it is delivered to avoid removing trees for a stockpile area. A stream specialist must be onsite during construction to successfully implement this design and ensure proper installation of the armor stone. This conceptual design is a guide. Design tolerance will allow for minor variations in grading and toe rock placement. These variations are unavoidable due to the variations of the rock surface and stream conditions during construction. This tolerance allows for a more natural, less engineered look to the remedial actions proposed. Prior to any land disturbance, exact location and depth of pipelines should be delineated by Williams' personnel. III. General Construction Notes and Best Management Practices 1. Miss Utility must be contacted and all utility lines must be located and marked prior to the start of any construction activities. 2. Stream diversion will be achieved by means of a temporary bypass pumping during construction. 3. If work is stopped for more than 15 days, temporary vegetative cover and/or matting will be applied to all disturbed areas. 4. No excess fill, construction material, or debris shall be stockpiled or stored in wetlands, riparian areas, and/or the 100-year floodplain. 5. Place materials in a location and manner which does not adversely impact surface or subsurface water flow into or out of wetlands, riparian areas, and/or the 100-year floodplain. 6. Do not use the excavated material as back fill if it contains waste metal products, unsightly debris, toxic materials, or any other deleterious substance. If additional backfill is required, use clean material free of waste metal products, unsightly debris, toxic material or any other deleterious substance. 7. Place heavy equipment on mats or suitably operate the equipment to prevent damage to AMERICAN LAND CONCEPTS 238 B MAIN STREET REISTERSTOWN, MARYLAND 21136 PHONE: (410)-526-2688 Conceptual Stream Stabilization Cardinal Gas Pipeline at the Tributary to Haw River wetlands, riparian areas, and/or the 100-year floodplain. 8. Repair and maintain fill so there is no permanent loss of wetlands, riparian areas, and/or permanent modification of the 100-year floodplain in excess of that lost under the originally authorized structure or fill. 9. Rectify any wetlands, riparian area, and/or 100-year floodplain temporarily impacted by any construction. 10. After construction has been completed, make post -construction grades and elevations the same as the original grades and elevations in temporarily impacted areas. 11. The disturbed area is to be revegetated with the native grasses and/or woody plants. IV. Soil Preparation 1. Soil Additives: Additives are to be applied per soils test taken prior to, during, and after construction. Soils will be amended per results. 2. Soil preparation: All areas to be seeded or planted shall be tilled to a minimum depth of 4 inches within the seeded areas and 4-6 inches within the woody plant areas. Any stones, roots, or other material larger than 3 inches will be removed. pH modifiers and/or other soil amendments specified in the soil test or as specified above will be added during the soil preparation. Re -compact the area. The final grade shall be smooth and even soil surface with loose, uniformly fine texture. All ridges and depressions will be removed. V. Planting 1. Temporary/nurse crop seeding will be completed immediately post construction and seedbed preparation is completed. Temporary/nurse crop seeding will be at minimum density to avoid competition with native, permanent species. 2. Permanent native seed mix will be completed in conjunction with or immediately following the nurse crop seeding. 3. Straw (from wheat or oats) will be spread over the seedbed at a minimum rate of 1-2 tons per acre to protect the soil subsurface, maintain moisture, and moderate soil temperatures for seed germination. Straw must be tacked town to prevent loss. 4. Woody Vegetation will be installed between March 1 to May 30 or October 1 to December 31. Planting materials will consist of container grown trees. All stock will be planted as received, no pruning will be done at the site. Stock not meeting specifications will be returned. All planting stock shall be protected from sun scald, desiccation, and structural damage during shipment to the site. Delivery of materials will be no sooner than one week prior to planting. Materials held for planting will be moistened and placed in cool, shaded areas until ready for placement. a. Woody plants will be planted at a minimum of 435 stems per acre (approximately 10' on center). b. Plant material shall be planted in holes that are twice the size of the root ball. When digging the hole, keep topsoil separate from subsoil. If the subsoil is high in clay, allow extra room (one-half again the height of the root ball). Backfill the hole with enough topsoil or peat moss to position the base of the tree at the same level as in the nursery. c. If the plant is in a container, carefully remove it, taking the soil surrounding the roots with it. This may require cutting the container. Loosen the twine and burlap at the top of balled-and-burlapped plants, and check to make sure that no other wrapping is present before planting. d. Before replacing subsoil, mix it with one-third peat moss or well -rotted manure. Backfill the hole, firming the soil as it is replaced, and leave a depression around the trunk within Rockingham County, North Carolina November 2019, Revised February 2020 the excavated area to hold water. Cover the base of the trunk to the same level as before it was removed. Water thoroughly, and rewater as necessary to keep the roots moist. e. If necessary, shelter trees to avoid predation. f. Cleanup and remaining trash or materials and dispose of properly offsite. VI. Maintenance Tree Fertilizing will be completed in late fall or early spring, before leaves emerge. Using a punchbar, crowbar, or auger, make holes 18 inches deep and about 2 ft apart around the drip line of each tree. Distribute the fertilizer evenly among the holes to bring it in contact with tree roots, and close. If invasive exotic plants are noted during routine inspections, and treated if necessary utilizing manual removal or an approved herbicide. Any use of herbicide will be used in the minimal quantity necessary, only be applied to the invasive exotic species, and will be of low toxicity to aquatic wildlife. Areas within the ROW will be routinely mowed to maintain the ROW. The areas immediately adjacent to the stream will be minimally mowed to allow the native seed mix to protect the riparian area. VII. Monitoring The restored area stream restoration and buffer plantings will be monitor to ensure the restored area is at a minimum functioning properly, no erosive conditions are occurring, no sediment is being transported into the stream, and the planted riparian will be at a sufficient density of 320 trees per acre at maturity for a period of 3 years. The riparian buffer will be monitored for an additional 2 years to ensure the sufficient tree density is reached. Photodocumentation at permanent photostations will be included in the monitoring report. The first 3 reports will be submitted to USACE and NC DEQ by October 31 st of each year after construction is completed. The additional 2 reports specifically focused on the riparian buffer will be only submitted to NC DEQ. If during the monitoring any erosion along the restored stream is detected, it shall be properly addressed to prevent sediment transport into the stream. If any changes to the design are necessary, USACE and NC DEQ will be contacted before proceeding forward with repairs. Hydrologic, vegetative, and soils data will be collected throughout the year. At a minimum each report will include: a. A map of the stream and riparian restoration area. b. Photographs showing views of the stream area taken from permanent stations and corresponding view directions. View direction will show the same area throughout the monitoring period. c. A report describing the overall conditions present at the stabilization area including: inspection of drop structures, bank armoring, vegetation viability, slope condition, and identification of any undesirable species of vegetation or wildlife that would compromise the integrity of the stabilized stream bank or riparian buffer. The report will suggest methods for removal and monitoring of undesirable species of vegetation and wildlife. d. If during the monitoring, any erosion along the restored stream is detected, it shall be properly addressed to prevent sediment transport into the stream. If any changes to the design are necessary, USACE and NC DEQ will be contacted before proceeding forward with repairs.
