The proposed actions consist of streambed stabilization to cover exposed pipelines, pipeline maintenance, and protection within CPC's maintained right -of -way (ROW). The proposed activities will require temporary disturbance to Hickory Creek, a perennial stream located in Guilford County (35.99166 °N, 79.84962 °W), North Carolina (Figure 1). Background CPC is committed to operating their pipelines and support facilities in a manner that protects the safety of the public, the environment, and its workforce. The proposed pipeline maintenance is required to restore pipeline protection and integrity. The ROW contains three CPC pipelines that transport refined petroleum, Line 22 (16 -inch diameter), and Lines 23 and 24 (8 -inch diameter). Recent heavy rain events have caused lateral migration of the streambed, and the associated downgrading has exposed Line 23 within the stream channel; thus, the require Pee- Construction Notification — NWP 18 Hickory Creek - Exposed Line V, May 5, 2014 Corblu Project No 02- 041901 pipeline protection has been lost. As required by the U S. Department of Transportation (USDOT), the pipeline regulatory authority, CPC must inspect, repair, and add pipeline protection for the exposed pipeline at this location. Proposed Activity in Waters of'the U.S. The maintenance activity will require temporary disturbance to approximately 75 linear feet of Hickory Creek to stabilize the streambed and banks to protect the existing pipelines at the project location To ensure the integrity of the Line 23 at this location, CPC' will initially inspect ,the line for any damage. This will require CPC to excavate a small pit at the maintenance location, which will 'allow CPC personnel to inspect the 'integrity of the subject pipeline segment To minimize sedimentation to Hickory Creek during inspection and subsequent maintenance activities, dam(s) constructed of sand bags, steel plates; or water - inflatable plastic dams will be temporarily placed upstream of the maintenance .area The stream flow will be pumped around the maintenance area and discharged immediately downstream via an energy dissipater to prevent stream scour, The pump will be sufficiently sized to accommodate the stream flow (Appendix A) As an alternative method to using a pump, CPC may use a steel pipe flume to convey the stream flow through the reach of stream to be disturbed. The flume will, be used to maintain flow to the downstream side of the disturbed area, and the excavation will be carried out under the flume (Appendix B) Both techniques allow the maintenance to take place without contact to flowing water (i e, "in the dry"), thus reducing downstream sedimentation Following the pipeline inspection and potential repairs, the stream banks reshaped to,'increase stability and prepare the `bank for the proposed matting system. The pipeline will be protected using pre - casted articulated grout revetment mats placed within CPC existing ROW, over Lines '22, 23, and 24 (Appendix G) Specifically„ the articulated grout mats and rip -rap will be placed, within 75 linear feet of the stream channel ,and, bank The quantity of "fill material" below the, plane of the ordinary high water mark will not exceed 24 cubic,yards Pre - Construction Notification — NWP 18 Hickory Creek -Exposed Line 3 May 5, 2014 Corblu Project No 02- 041901 During the maintenance and subsequent stabilization CP`C's Soil Erosion and Sedimentation Control Plan will be implemented to protect the stream from sedimentation (Appendix D). There will be minimal disturbance to jurisdictional waters located outside of CPC's ROW Nationwide Permit General Conditions Summary We have provided 'the 'following 'information to document compliance with the USACE, NWP ,general conditions Each condition and �subcategory'is itemized below General Condition, 1 — Navigation The proposed project does not occur within navigable waters.

The objectives of this plan are to gismal,gaidelines for controDiag Tiro on end sedimentation andto specify cifiria. fix ensitive or pardixilarly suable sot areas. Tie pion incorporates measures to control erosion and sedimentation including miaimizmg cover removal, limiting the time of exposure, lin iting the flow of water onto the disturbed right-of -way, and ffite=g or settling out sediment fom water flowing from the.rigGt -of -way. The primary objective of the,soil erosion,and sediment control.pIan;is,to reduce the area and duration of soildisturbance and,reestablish;permanent vegetation sasoon,atier conshuction,as possible, thereby m;ri, —*�+T long -term erosion and sedimentation. Some erosion is inevitable during construction; however, the plan includes measures to ,reduce erosion to the minimum practical. Colonial Pipeline Company plin "to rednoe sold erosion and provide sediment control during the repair of the pipeline at the project site by incorporating the following measures: • Water pumped fromthe construction area as part of the dewatering operation from the e=avation wiillibe 5ltered'through silt,fiit!ration bass and discharged to a well- vegetated area. • All work wM be eonfined'witliin the existing right -of -way: BU&edhaybalwand sih *nce wM befinsWW around the worb*e�and maintained until vegetadw is esW)H shed. Proper cantob wA be added iinewsawy daring construction. • All'ternos and conditions within Nationwide Permit 3 willbe followed. • Erosion control measures will be installed prior to oonducting any sod disturbing activities associated with the pipeline, maintenance activity: • Clearing,of vegetation will be kept to an absolute minimum and confined to the existing pipeline easement area. The easement area is 50 feet in width and devoid of large trees The right of way is vegetated with undergrowth, grasses and other short vegetation. • Vegetation wig be,reestablished within disturbed area and along stream banks as soon, as possiiblempon completion of work. Disturbed areas will be seeded with a wetland seed mixture • All erosion and sediment control measures will be inspected every two weeks,at a minimum and after every sigaificart ,xainfall event,of o.5 inclr,or more until disturbed areas have been stabilized. Identified damages to control measures must be repaired immediately. Refiase and Waisbe Disposal CQloniaYs r epreseMdve will not aIlow the Contractor to discard a w litter, including Paper, bottles, cans, rem,sacks, w ding rod stubs, fuel, cranhcaseArainm& casting materials, equipment, and junk pipe in the ditch or along t1wright -*f -way. All refuse must be, collected and disposed in accordance with oomp®ay spedons. Personnel wM be instnuted °regarding the correctWocedure for waste disposal. Maintenance/Laspeadon Prooedures The following inspection and maintenancepractices wffbe.implemented to.maintain erosion and sediment controls: L AD control measures wID be inspected every twoweelm at a,minimum and Mowin arty storm event of 0.5 inch orgreater. 2. All control measures will,be maintainedin good worhug order. If a repair is necessary, it W be initiated within 24 hours of the report. g. Built-up sediment will be,removed from silt. fences when it has reached one - third the height -of the fence. 4. Silt fences will be inspected for depth of sediment, tears, seeure attachment of the fabric to the ton rm, e posts, and 8placement of the posts in the V=cL 5. Temporary and,permanent seeding and planting will be inspected for bare spots, washouts,andnheatthy growth. 6. Colonial Pipeline Company will select individuals to be responsible for inspections, maintenance and repair activities,, and completion of the inspecttan and 'maintenance report. Personnel selected for,inspection and maintenance responsibilities will receive training from Colonial Pipeline Company or its representative. Personnel must be trained in all practices 'necessary for maintaining the erosion +an&sediment controis,nsed on-site.

Non- regulated waters /wetlands (check if applicable):3 Q Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional Explain i Boxes checked below shall be supported,by completing the,appropnate sections in Section iII below Z For purposes of this form, an RPW is defined as a tributary that is not a TNW and thattypically flows year -round or has continuous flow at -least "seasonally" (e g , typically 3 months) 3 Supporting documentation is presented,m,Section III F SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO'TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resourcesis a TNW, complete Section III.A.1 and Section III.D.1. only;, if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below 1. TNW Identify TNW Summarize rationale supporting determination 2. Wetland- adjacent to TNW Summarize rationale supporting, conclusion that wetland is "adjacent` B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non - navigable tributaries of TNWs where the tributaries are "relatively permanent, waters" (RPWs), i.e. tributaries that typically flow year -round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is'also jurisdictional. If the aquatic resource is not a TNW, but has year -round (perennial) flow, skip to Section III.D.2. If the aquatic, resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetlandthatis adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts,and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as,a matter of law. If the waterbody° is not an RPW, or a,wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus, evaluation must considerlhe tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary,, or its•adjacent wetlands, or both.

SIGNIFICANT PLEXUS DETERMINATION A significant nexus,analysis will,assess the flow characteristics and functions of the tributary itself and the functions performed by any, wetlands, adjacent to the tributary to determine if they significantly affect,the chemical, physical, and biological'integrity of a'TNW. For each of the following situations, a significant nexus exists if the tributary,, in, combination with all of its adjacent wetlands, has,more than ,a speculativeror,insubstantial ,effect on theFchemical, physical „and /or,biological integrity of,a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate,to determine significant nexus based solely on any'specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between theifeatures documented and the,effects on the TNW, as1dentified in the,Rapanos Guidance and +discussed,in the Instructional Guidebook. Factors,to`consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any),`have the- capacity•to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW9 • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and,lifecycle support,funchons for fish and other species, such as feeding, nesting, spawning, or rearing young -for species that are present in the TNW9 • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs9 40 Does the tnbutary,zm combination with its,adjacent wetlands (if any), havc�other relationships to the physical, chemical, or biological integrity of the TNW9 Note: -the above list,of considerations is not inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus,findings for non -RPW that has no adjacent wetlands,and flows directly�or indirectly into TNWs. Explain findings of,presence`ovabsence of significant nexus below,,based on the.tnbutary itself, then go to Section III D 2.
