We are also requesting a 401 WQC for the proposed impacts. The proposed project does not require a Buffer Authorization. The proposed force main easement if ±15,850 if in length and runs from an existing pump station east of Apple Blossom Lane (Lat: 36.118084 °N; Long: - 79.358156 °W), then runs south on the east side of Apple Blossom Lane, then runs east along the south side of Basil Holt Road, then runs south along the east side of Roxboro Road (NC 49), then runs west on the north side of the Haw River Bypass (Hwy 70) where is crosses the Haw River, then runs north along the west side of the Haw River to the existing East Burlington Waste Water Treatment Plant (Lat: 36.o96603 °N; Long: - 79.374301 °W) The proposed project is located in the Green Level /Haw River townships, in Alamance County. The project is located within the Cape Fear River Basin (HUC 03030002) and onsite waters drain to the Haw River. The Water Quality Classification for the Haw River is SW -V; NSW and the Stream Index is: 16- (10.5). Project Purpose The purpose for the Green Level to Burlington force main project is to replace the existing Green Level gravity outfall which discharges into the Town of Haw River sewer system. This Green Level sewer outfall and the Town of Haw River system have experienced periodic surcharges and backups due to condition and age of both systems. The force main will completely replace the aged Green Level gravity outfall and remove that flow from the Town of Haw River sewer system, reducing the potential for spills resulting from surcharges and backups. Project History Onsite wetlands were delineated by Withers and Ravenel in December 2013. Due to the nature of the project, W &R is requesting a Preliminary JD for jurisdictional features within the proposed easement alignment in conjunction with issuance of the NWP 12. The Preliminary JD Request and supporting documentation has been provided as an Appendix. 1410 Commonwealth Drive I Suite 1011 Wilmington, NC 28403 1 tel: 910.256.9277 1 fax: 910.256.2584 www.withersravene[.com I License No. C -0832 Sue Homewood with NCDWR issued a Buffer Determination Letter for the proposed alignment on 1/28/14. A copy of the Buffer Determination Letter has been provided as an Appendix. The project was reviewed by NC Division of Water Quality; Infrastructure Finance Section for NEPA compliance, and issued a letter, dated April 1o, 2013, documenting that the project is exempt from inter - agency review and preparation of additional environmental documents is not required. A copy of the NCDWQ; Infrastructure Finance Section letterhas been provided as an Appendix. Proposed Impacts The proposed impacts consist of 0.2o acres of temporary wetland impacts and 26 if of permanent stream impacts for construction of the proposed force main. The proposed 0.2o acres of temporary wetland impacts will occur from installation of the force main by conventional trench and backfill methods, as well as the 20' temporary construction corridor within the wetlands beyond the easement which is necessary for construction of the force main. The proposed 26 if of permanent stream impacts (Impact #4) will occur to a small channel (26 if in total length) which begins at the edge of the ROW as a result of erosion from runoff from the adjacent pasture and the channel runs along the toe of slope into a 30' culvert beneath Hwy 70 which discharges directly into a farm pond. Sue Homewood with DWR determined that this feature was an ephemeral channel for the purpose of buffer subjectivity, but indicated that she thought that the Corps of Engineers would consider this an intermittent stream. Due to the time constraints associated with the permitting of this project, this feature has been considered an intermittent stream for permitting purposes. The stream consists of a small, shallow, eroded channel that does not have typical stream structure, which would be extremely hard to "restore" in the post - development condition. When evaluating this feature for temporary or permanent impacts, it was determined that it would be impossible to "restore" the feature to pre- construction conditions. Also, if this feature was only temporarily impacted and "restored ", the stream would flow down the sewer easement and into the 30" culvert. The unstable condition of the soils after construction could result in heavy erosion, presenting a risk of eventually exposing the force main, as well as sedimentation of downstream waters. Therefore, it was determined that the best solution would be to permanently impact the stream by creating a swale lined with a geotextile fabric and rip -rap to maintain existing conveyance and permanently prevent the risk of exposure of the force main and sedimentation of downstream waters. Please refer to Exhibit 6 for details on the swale alignment. The project will also result in o.o9 acres of "permanent wetland conversion" impacts from the clearing of forested wetlands for installation of the force main and perpetual maintenance of the entire 15' easement. Please note that the "permanent wetland conversion" impacts are only applicable to the Corps of Engineers and should not be addressed in the 401 WQC. The proposed project has also been designed to avoid impacts to Jordan Lake riparian buffers. Specifically, impacts to riparian buffer have been avoided by installing certain sections of the force main within the existing fill slope of Hwy 7o, as well directional drilling the force main beneath streams within the proposed alignment, as well as the Haw River. The directional drill entrance /exit pits have been located beyond the riparian buffers. The connection of the force to the WWTP will occur within the riparian buffers associated with the Haw River. However, this area is currently maintained as ongoing use for operation of the WWTP. In an email dated 2/4/14, Sue Homewood WITHERS RAVENEL Page 2 of ENGINEERS I PLANNERS I SURVEYORS with NC DWR determined that the maintained area within the riparian buffers was an existing and ongoing use for the WWTP and therefore exempt from the Jordan Lake Buffer Rules. Ms. Homewood also determined that disturbance to this area for connection of the force main to the WWTP was also exempt from Jordan Lake Buffer Rules since it will occur within an exempt area within the WWTP. A copy of Ms. Homewood's email has been provided as an Appendix. Therefore, the proposed project will not result in impacts to riparian buffers that require authorization. Avoidance and Minimization Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands, "waters" and riparian buffers could be minimized. Wetland impacts have been minimized to temporary impacts necessary for installation of the force main. The easement through the wetlands has been reduced to 15' within the wetlands. Upon completion of construction, the temporary wetland impact areas will be seeded with a wetland seed mix accordingto the Sediment & Erosion Control plans. Impacts to streams and the Haw River, as well as riparian buffers, have been avoided by constructing the force main within the existing ROW fill slope where allowed by NCDOT. Also, the force main will be installed via directional drilling to cross streams and the Haw River. Mitigation Stream Mitigation Since permanent stream impacts are less than 150 If, the applicant is not proposing stream mitigation. Wetland Mitigation There is no mitigation proposed fortemporary wetland impacts. The proposed project will result in o.og acres of permanent wetland conversion impacts as a result of the perpetual maintenance of the 15' easement through wetlands. Since the permanent wetland conversion impacts are less than o.10 acres, no mitigation is proposed. The current request is for 0.2o acres of temporary wetland impacts, 26 if of permanent stream impacts and o.o9 acres of permanent wetland conversion impacts (see the attached maps and PCN for details).

The "stream" begins at the fence line along the ROW and runs along the toe of slope and into a 30" culvert beneath Hwy 70 Bypass. Sue Homewood with DWR determined this feature to be an ephemeral channel, not subject to buffers, but indicated she thought that the Corps may consider this feature to be an intermittent stream. Due to the time constraints associated with this project, we are considering this feature an intermittent stream for permitting purposes. Based on the current characteristics of the channel, it would be impossible to "restore" this feature to pre- construction conditions and therefore, permanent impacts are being assess for this feature. The proposed permanent impact will consist of converting this feature to a swale lined with geotextile fabric and rip -rap to maintain existing conveyance once construction is complete.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that impacts to wetlands, "waters" and riparian buffers could be minimized. Wetland impacts have been minimized to temporary impacts necessary for installation of the force main. The easement through the wetlands has been reduced to 15' within the wetlands. Upon completion of construction, the temporary wetland impact areas will be seeded with a wetland seed mix according to the Sediment & Erosion Control plans. Impacts to streams and the Haw River, as well as riparian buffers, have been avoided by constructing the force main within the existing ROW fill slope where allowed by NCDOT. Also, the force main will be installed via directional drilling to cross streams and the Haw River. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The force main will be installed using directional drill to avoid stream impacts at the Haw River (Exhibit 2) crossing and the stream on the south side of the Haw River (Exhibit 1) in order to avoid stream /buffer impacts at these locations. 2.

The attached maps depict the approximate locations of the streams that were reviewed. Feature D was determined to be an ephemeral feature and not to be subject to the Jordan Buffer regulations, however this feature may be considered a jurisdictional stream by the US Army Corps of Engineers. Feature B was determined to be a perennial stream "approximately shown" on the Alamance County Soil Survey and Feature F was determined to be an intermittent stream "approximately shown" on the Alamance County Soil Survey, therefore both Feature B and Feature D are subject to the Jordan Buffer regulations. All other features shown on the attached map are accurate as depicted and subject to the Jordan Buffer regulations. Please note that at the time of this letter, all intermittent and perennial stream channels and jurisdictional wetlands found on the property are subject to the mitigation rules cited above. These regulations are subject to change in the future. The owner (or future owners) should notify the Division (and other relevant agencies) of this decision in any future correspondences concerning this property. This on -site determination shall expire five (5) years from the date of this letter.

WITH ERS � MAVEN EL ENGINEERS) PLANNERS I SURVEYORS January 29, 2014 Sue Homewood Environmental Specialist NCDENR 585 Waughtown St Winston - Salem, NC 27107 Subject: Basil Holt— Burlington Force Main Project Haw River Buffer Determination Dear Ms. Homewood: Thank you for spending the time with Troy Beasley of our company this past Thursday, the 23rd, in very cold conditions, to review and clarify the surface water buffers for the subject project. At your recommendation, we are providing this letter to request your concurrence for a determination of "existing and ongoing use" for the mowed and maintained area at the City of Burlington East Wastewater Treatment Plant (WWTP) between the flood wall and the Haw River because this area is critical for maintenance and operation of the WWTP. I met with Bob Patterson and Michael Layne at the WWTP on Friday the 24Th to review the area and obtain their input and explanation as to why the mowed area is critical as maintenance area for the plant. Bob Patterson is Water Resources Director and Michael Layne is Field Operations Manager for the City of Burlington. Please refer to the attached sketch as an aid in helping show and define the areas described in reasons presented below that explain why the mowed area is critical as maintenance area for the plant. The principal reason for maintaining the area as mowed lawn is for access and maintenance around the flood wall to protect the wall footing. The flood wall is 10 feet high and protects critical portions of the WWTP from the I% probability flood but it relies on the footing to keep it functional. The flood wall is supported on a 9.5 -foot wide spread footing which extends about 6 feet on the river side of the wall. The footing is covered by soil and resides on soil, so keeping the soil above, along and in front of the flood wall from being compromised or eroding is crucial for protecting the integrity of the wall. Protecting the integrity of the soil along the flood wall is similar to the treatment that is required for maintaining the integrity of a water reservoir earthen embankment. The area must be kept free of all trees or vegetation with large root balls or root structures and the area must be kept fully covered with either riprap or fine, deep- rooting vegetation to protect is from erosion. The WWTP has determined that a suitable distance needed as a flood wall protection zone should be three times the width of 115 MacKenan Drive I Cary, NC 275111 tel.: 919.469.3340 1 fax: 919.467.6008 I www.withersravenel.com I License No. C -0832 1410 Commonwealth Drive I Suite 1o1 I Wilmington, NC 28403 1 tel: 910.256.9277 I fax: 910.256.2584 7011 Albert Pick Road, Suite G I Greensboro, NC 274091 tel: 336.605.3009 1 fax: 919.467.6008 Buffer Determination Letter Basil Holt- Burlington Force Main Page 2 of 2 January 29, 2014 the footing which is 18 feet. Beyond that distance, WWTP staff feels that even a mature tree would present a minimal probability for the root growth to compromise the flood wall protection zone because of the drop off to the river. The 18400t flood wall protection zone is shown as the green hatched area on Attachment A. Although rip rap would have been a less maintenance intensive protective cover, WWTP staff chose to maintain the area as grass, thus providing a more natural treatment. Another WWTP functional requirement of the area in front of the flood wall is the accommodation of equipment access to inspect and maintain the various pipes that connect to the WWTP. The 2T Rules require that the easement or a suitable maintenance area above sanitary sewer lines and sewer piping must be maintained to allow access for inspection and maintenance. The easement or maintenance areas of the various pipes that run through the area outside of the flood wall are shown on the attached sketch with blue hatching and the equipment access as red hatching. The easement or prescribed maintenance area above each pipe shown is the Burlington typical 30 feet width dedicated for this purpose. The Burlington Water Resources Department has determined that all of the mowed /maintained area between the flood wall and the river is critical to the maintenance and operation of the WWTP and the appurtenant piping. Therefore, we are requesting concurrence from NCDWR that the entire mowed /maintained portion of the riparian buffers between the flood wall and the Haw River be considered an "existing and ongoing use ", as this area is critical to the operation and maintenance of the WWTP, and therefore exempt from Jordan Lake Buffer Rules. Furthermore, we are requesting concurrence that any proposed construction within the referenced mowed /maintained portion of the riparian buffers for installation of the Basil Holt- Burlington Forcemain line and connection to the WWTP would also be consistent with the "existing and ongoing use" at the WWTP and therefore considered exempt from Jordan Lake Buffer Rules. Please let me know if you have any questions or require any additional information to complete you review. Sincerely, WITHERS &RAVENEL, INC. Michael R. Koser, P.E. Enclosure cc.

The planned work includes the following: (1) replace the existing 100 gallons per minute (gpm) Basil Holt Pump Station with a new 400 gpm pump station to mate with the forcemain to Burlington; (2) extend the Otter Creek forcemain approximately 375 feet to a new discharge point to gravity flow to Basil Holt Pump Station; (3) abandon approximately 2,700 linear feet (l.f.) of the Herman Johnson Pump Station forcemain and move the discharge point to gravity flow into Basil Holt Pump Station; (4) add approximately 2601.f. of gravity sewer to connect Hwy 49 gravity sewer discharge to Basil Holt Pump Station to redirect flow from the Green Level Outfall and plug the outfall; and (5) construct approximately 16,3001.f. of 8 -inch forcemain from the Basil Holt Pump Station to the East Burlington WWTP. The above named applicant intends to apply for assistance from the State Revolving Fund program to construct the wastewater facilities described above. The North Carolina Division of Water Quality (DWQ) has conducted a review of the project in accordance with the procedures (NCAC 15A Subchapter 1C) for conformance with the North Carolina Environmental Policy Act. The DWQ has determined that this project is below the minor construction activities threshold outlined in 15A NCAC 0 1 C .0408; therefore, the project is exempt from inter - agency review, and the preparation of additional environmental documents is not required. This determination shall become effective upon its distribution by DWQ and will be available on the DWQ Infrastructure Finance Section's website (http://portal.ncdeiir.org/web/wq/ifs/er/fonsis . This determination can be revoked at any time adverse information is made available. The documentation to support this decision will be on file with the North Carolina Department of Environment and Natural Resources, Division of Water Quality, Infrastructure Finance Section, and is available for public scrutiny upon request.
