Stowe, P.E., City Engineer City of Newton Post Office Box 550 Newton, North Carolina 28658 Subject: Rudisill Transportation Pumping and Hauling of Wastewater Catawba County Dear Mr. Stowe: Information provided to this Office indicates that the City of Newton may be involved in the pumping and hauling of wastewater from the subject facility. More specifically, it is our understanding that the City entered into an agreement with Rudisill Transporation whereby the City would install a temporary holding tank from which wastewater from Rudisill Transportation would be collected and then pumped and hauled for disposal at the City's WWTP. This pumping and hauling arrangement between the City and Rudisill Transporation alledgely began in the summer of 1999 and was to continue until such time as municipal sewer service became available to the property (anticipated spring/summer 2000). Please be advised that a permit from the Division of Water Quality is required for pump and haul (P&H) operations of domestic wastewater, per 15 NCAC 2H .0205 (d) (13). This Office has no record of issuance of a P&H Permit for the wastewater disposal operation described above. For this reason, it is requested that this Office be advised in writing by no later than June 16, 2000 of whether or not wastewater is being (or has been) pump and hauled from the subject facility, and if so, when the operation began. Also, provide the anticipated date when municipal sewer service will be available to serve this site. If you have any questions regarding this matter, please contact Mr. Michael Parker or me at (704) 663-1699. Sincerely, D D. Rex Gleason, P.E.

CONCLUSIONS AND RECOMMENDATIONS APPENDIX A COST ESTIMATES APPENDIX B CATAWBA COUNTY SOILS INFORMATION A. INTRODUCTION The Sherrills Ford and Terrell area near Lake Norman has experienced growth in recent years due to the attractive features associated with Lake Norman. The increased development in the area has resulted in a need for an improved wastewater treatment system to meet the residential, commercial and industrial needs and preserve the water quality of Lake Norman and its tributary streams. According to the Catawba County Health Department, approximately 26% of all septic tank permits issued in Sherrills Ford are repair permits for failed septic tank systems. In addition, CommScope and Prodelin industries, as well as the Sherrills Ford Elementary School would all benefit from an improved wastewater treatment system. Also, the N.C. 150 corridor includes potential commercial customers and this corridor has been identified by the County as a growth area for future commercial and residential development. B. PROPOSED WASTEWATER TREATMENT FACILITY Several engineering studies have been performed in the past six (6) years to evaluate potential wastewater collection and treatment systems in the Sherrills Ford and Terrell area. Based on these studies and wastewater flow projections, it has been recommended that a 0.5 million gallons per day (mgd) wastewater treatment facility be constructed with the capability to be expanded to up to 3.0 mgd in future years. Based on discussions with the Mooresville regional office of the North Carolina Division of Water Quality (NCDWQ), the location of the treated wastewater discharge is proposed to be into the main stream channel of Lake Norman (Catawba River). Extensive research has been conducted by the County and their consultants to identify Pagc l Li feasible sites for the proposed wastewater treatment plant. Several potential sites were subsequently identified by a task force comprised of community residents and County staff. A detailed site evaluation process has been completed for each site with the site known as Site 119 selected as the primary site for a proposed wastewater treatment plant. The site is already encumbered by an existing railroad, and the property along the western boundary can remain undeveloped to provide a significant permanent natural buffer Site 119 is located on Si g Bridge Road south of N_C. 150 as shown in Figure I -A, with a schematic of the proposed wastewater treatment plant shown in Fieure 1-B, C. NEED FOR PROJECT Based on information published by the County, there are at least 5,500 septic tanks in the Sherrills Ford/Terrell region, As mentioned .earlier, approximately 26% of all septic tank permits issued in Sherrills Ford are repair permits for failed septic tank systems. It is apparent that the relatively high potential for failing septic tanks jeopardizes the water quality of drinking wells in the area, as well as Lake Norman. The County would like to provide for an alternative to the use of septic tanks to avoid future large concentrations of -residential septic tanks in the Lake Norman area. Therefore, the proposed wastewater system will have the capacity to serve development on Island Point Road and other pending developments in the vicinity of Sherrills Ford Road and the northern Sherrills Ford area_ According Reference No. 1 listed on page 6, there are at least eight (8) planned developments identified for approval in the area, with a total first phase construction of approximately- '677tilesidences., In addition., other undeveloped lots in the area provide for the potential of an additional 263 residences, for a total estimated potential of 939 new residences PROPOSED WASTEWATER TREATMENT PLANT LOCATION MAP CATAWBA COUNTY, NORTH CAROUNA FIGURE I -A APPROXIMATE ..::> :: ; SCALE: = 2 00' LOCATION OF SITE No.119 eG S a 0 C I A.

These facilities are described in the following paragraphs and have a marginal history as to compliance with their existing discharge permit limits. Each of the two treatment facilities discharge into very low flow streams, which are tributaries to Lake Norman. The construction of the proposed new wastewater treatment facility would enable these smaller treatment facilities and respective discharges to be removed, and discharged instead to the main channel of Lake Norman. CommScope Industries and Prodelin are served by a small package type WWTP at the CommScope facility which receives and treats the wastewater generated from the two facilities. The existing wastewater treatment plant has an NPDES permit (Permit No. NC0034754) to discharge 20,000 gallons per day (gpd) into a tributary of Terrapin Creek which flows into Lake Norman. The summer permit limits include 16 mg/I for BOD, 30 mg/1 for TSS, and 2 mgll for ammonia. The NCDWQ regional office has previously indicated that the receiving capacity of Terrapin Creek is limited due to its relatively low flow, and an increase to CommScope's permitted discharge may not be possible. CommScope Industries has indicated that employment may be reduced unless additional wastewater treatment and discharge capacity and can be obtained. The CommScope Industries facility employs approximately 1600 people, while Prodelin employees approximately 80 people. Sherrills Ford Elementary School is currently served by a recirculating sand filter system which receives and treats the wastewater generated from the school. The existing wastewater treatment facility has an NPDES permit (Permit No. NC0045438) to discharge 7,000 gpd into an unnamed tributary of Lake Norman. The permit limits include 30 mg/l for BOD, 30 mg/l for TSS ['ago 3 { and 4.0 mg/I for ammonia. According to the Catawba County school board, the school has received several violations of their NPDES permit in the past few years. There is a great need for an improved wastewater treatment system in order to preserve the drinking water sources and the water quality of Lake Norman. It is apparent that the reduction of septic tanks and the elimination of these existing discharges to the low -flow tributaries of Lake Norman are sound methods toward meeting this environmental need. D. WASTEWATER FLOW PROJECTIONS The County proposes to provide service to CommScope Industries, Sherrills Ford Elementary School, Prodelin, and the estimated 939 planned residences. CommScope has indicated that a future wastewater flow of 40,000 gpd is desired. Sherrills Ford Elementary School has a projected wastewater flow generation of 10,000 gpd, and Prodelin's projected wastewater flow is 10,000 gpd. Assuming an average of three (3) bedrooms per residence and utilizing NCDWQ criteria of 120 gpd per bedroom, the estimated flow generated by the planned residential development is 338,000 gpd. Including the facilities listed above and other potential commercial establishments that could be served, the projected wastewater flow fdr the initial service area during the first ten (10) years of the planning period is 416,500 gpd. According to State regulations, the County would be required to begin planning to expand the wastewater treatment facilities when flows reach 80% capacity. Therefore, it is recommended that a 0.5 mgd wastewater treatment facility be constructed initially to accommodate the projected flows. With a 0.5 mgd facility, it would not be necessary to submit a plan of action for expansion until flows reach 0.4 mgd, which would be around 2012. Pagc 4 In 1994, McGill Associates prepared a study (Reference No.2 listed on page 6) which identified the future service area in southeast Catawba County and provided wastewater flow projections. Utilizing these flow projections as a base, and adding the Northern Sherrills Ford service area, CommScope and Prodelin (which were not included in the 1994 study), results in a total projected flow for the future service area in 2022 of 2,412,835 gpd. The tables below show the projected flows for the initial service area and for the future service area. Figure I-C shows the future service area.

SPECULATIVE NPDES FERN] IF I 4 rfd ITS Although speculative NPDES neimit Iffitits have not 'vet been issued by the NCDWQ for the proposed discharge to the main stream channel, based on past discussions with the NCDWQ Mooresville office, it is anticipated that NPDES permit lfirlits will be in the range of 15 rn for BOD, 30 mgd for TSS, 4 rngl for ammonia and 0 028 mgil for chlorine These are the limits of a current permit held for a similar discharge to the main stream channel F.

DESCRIPTION OF ALTERNATIVES This section of the report will evaluate several alternatives for the treatment and disposal of the treated wastewater. Since the collection system that is constructed to serve the individual customers will be similar for all the alternatives, this alternatives analysis will address only the major pump stations, force mains and main gravity sewer interceptors associated with the proposed collection systems. The alternatives listed below will be evaluated for an initial flow of 0.5 mgd and an ultimate flow of 3.0 mgd at the end of the 20-year planning period. For the purposes of this report, it will be assumed that the construction of the initial phase facilities will be completed in 2002, and construction of the ultimate phase facilities for 3.0 mgd capacity will be completed in 2017. Practically, there would most likely be intermediate system and facility expansions between 0.5 mgd and 3.0 mgd, but for the purpose of comparing the alternatives on a present value basis, the assumed timing of the system and facility expansions is sufficient. The following alternatives have been evaluated: 1. Construction of a new WWTP with discharge to main stream channel 2. Transmission of wastewater to existing Mid -South Utilities WWTP 3. Transmission of wastewater to existing Town of Mooresville WWTP Page 7 4. Transmission of wastewater to existing City of Newton WWTP 5. Transmission of wastewater to existing Lincoln County WWTP 6. Drip or spray irrigation of treated effluent on land in area B. ALTERNATIVES ANALYSIS 1. Alternative No. 1 — Construction of a new wastewater treatment plant AIternative No. 1 consists of the construction of a transmission system in the proposed service area and a new wastewater treatment plant at Site I19 to serve the Sherrills Ford/Terrell area. The initial capacity of the wastewater treatment plant would be 0.5 mgd, with an expansion to 3.0 mgd occurring in 2017. This alternative would satisfy the needs and goals of the project previously described in Section 1. As mentioned earlier, an extensive site selection process was conducted by the County to identify a site that would minimize impacts to the environment. This particular site provides excellent natural buffers to mitigate potential visual, noise and odor impacts. The proposed wastewater treatment plant would consist of an influent pump station, bar screen, dual train treatment units to provide aeration and clarification, a chlorine contact basin and an effluent pump station. The effluent pump station would pump the effluent through a force main along N.C. 150 to discharge the effluent into the main stream channel of Lake Norman. The estimated project capital cost for this alternative is $8,186,000 for the initial phase. A detailed cost estimate for both phases is provided in Appendix A, and a schematic of the proposed system is provided at the end of this section. Page 8 2. Alternative No. 2 — Transmit wastewater to existing Mid -South WWTP According to information provided by Mid -South Water Systems and NCDWQ, Mid -South Water Systems owns a 100,000 gpd wastewater treatment plant that is scheduled to become operational in the near future. The wastewater treatment plant is located approximately 1' miles east of the NC 150 bridge that crosses Lake Norman, and the plant wiII discharge treated effluent through a transmission line that discharges to the main stream channel near the NC 150 bridge. Mid -South has an NPDES permit to discharge 300,000 gpd at this location, although the wastewater treatment plant has been constructed to a capacity of only 100,000 gpd. This alternative includes pump stations and sewer lines to transmit the wastewater to a main pump station located at Site 119 on the east side of Lake Norman. The main pump station would transmit the wastewater through a force main, across the NC 150 bridge, and to the Mid -South WWTP. Expansions of the Mid -South WWTP would be required for both the initial phase and the ultimate phase, as well as upgrades to the discharge pipeline to the main stream channel of Lake Norman. The estimated project capital cost for this alternative is $9,155,400 for the initial phase. A detailed cost estimate for both phases is provided in Appendix A, and a schematic of the proposed system is provided at the end of this section. 3. Alternative No. 3 — Transmit wastewater to Town of Mooresville WWTP According to the Town Engineer for the Town of Mooresville, the Town of Mooresville owns a 5.2 mgd capacity wastewater treatment plant located south of Town adjacent to Dye Creek. The plant currently receives flow of approximately 3.2 mgd. The Page 9 Town Engineer indicated that, if they were to enter into a formal agreement with Catawba County to receive flow from the Sherrills Ford/Terrell area, the Town could probably receive the initial 0,5 mgd estimated flow without expanding their wastewater treatment plant. Therefore, the initial phase of this alternative does pot include a wastewater treatment plant expansion, but does include a charge ofn-pers,alionifrom the Town of Mooresville, for Catawba County to purchase treatment capacity at the plant. The ultimate phase does include a 2.5 mgd expansion of the Mooresville WWTP This alternative also includes a main pump station at Site 119 on the east side of Lake Norman to transmit the wastewater from Catawba County to the Town of Mooresville. The estimated project capital cost for this alternative is $9,095,000 for the initial phase. A detailed cost estimate for both phases is provided in Appendix A, and a schematic of the proposed system is provided at the end of this section. 4. Alternative No. 4 Transmission toCitv of Newton WWTP This alternative consists of pump stations and sewer lines to transmit the wastewater generated in the Sherrills Ford/Terrell area to the existing City of Newton. WWTP. The City of Newton has a 5.0 mgd design capacity wastewater treatment plant, Jr with an NPDES perrnit to discharge up to -7.,/5 mgd. The current average flow is approximately 2.6 mgd. it is assumed that the Newton WWTP has adequate capacity to receive the initial flow of 0.5 mgd, but an expansion would be required for the remaining 2.5 mgd of future projected flow A capacity purchase charge of S2 per gallon has been included for the County to purchase treatment capacity at the Newton WWTP. This vag, alternative includes four (4) pump stations between Sherrills Ford and the Newton WWTP, and a 2,5 mgd expansion of the Newton WWTP m 2017 to accommodate the new wastewater flows, Cornpared to Alternative No I, this alternative would have „/ 4) 54 td. Cif „ several negative environmental irripacts, The City of Newton discharges to a smaller stream (South Fork Clark (reek) with less ability to assimilate the treated wastewater flows, Also, the higher quantity of punm stations and length of sewer force main ( (2)70d increases the potential for sewer overflows due to power otitages, mechanical failures or force main leaks. The estimated project cost for this alternative is $11,179,000 for the initial phase A detailed project cost estimate for both phases is provided in Appendix A, and a schematic showing the proposed transmission system is provided at the end of this section 5 Alternative No. 5-- Transmission to Lincoln County WWTP This alternative consists of a pump station and force main to transmit the wastewater generated in the Sherrills Ford/Terrell area to the existing Forney Creek WWTP in Lincoln County, The Forney Creek sNWTP has a current capacity of 0 75 mgd, This alternative includes pump stations at CommScope, Sherrills Ford Fementary School and Island Point, gravity' sewer lines and force mains to convey flow' to and between the pump stations, a transmission pump station at Sherrills Ford Road, a Sesser transmission force rnain between the Sherrills Ford Road pump station and the Forney Creek WV) -FP, and expansion of the Forney Creek WWTP to accommodate the ness kvaste‘vater flows The exi,stinia wastewater treatment plant is site restricted, so additional land %you'd Pap,: 11 probably need to be acquired to expand the plant. Also, based on discussions with the NCDWQ regional office, it is also likely that the discharge point would need to be relocated for the future 3.0 mgd flow. Therefore, extension of a 30-inch gravity effluent line to Killian Creek has been included in the second phase of the project. The estimated project cost for this alternative is $10,450,700 for the initial phase. A detailed project cost estimate for both phases is provided in Appendix A, and a schematic showing the proposed transmission system is provided at the end of this section. 6. Alternative No. 6 — Drip or Spray Irrigation of Effluent Alternative No. 6 includes the construction of the proposed WWTP, but instead of discharging the effluent to Lake Norman, the treated effluent is applied to land in the area by either drip or spray irrigation. Copies of the County soils map and accompanying soils characteristics are provided in the Appendix for reference. For these types of suitable soils in the area, a best case loading rate for the treated effluent is 0.15 gpd/SF. Utilizing this loading rate, 76.5 acres of effective area would be required for the 0.5 mgd of treated effluent, and approximately 460 acres would be required for the future 3.0 mgd flow, not including setbacks. According to State regulations, drip irrigation systems require 50 foot setbacks, and spray irrigation systems require 150 foot setbacks from property lines. Therefore, a drip irrigation system will be less costly than a spray irrigation system, and the remainder of this discussion will be pertaining to a drip irrigation system. Utilizing the 50-feet setback requirement, a drip irrigation site would need to have a total area of approximately 85 acres for the 0.5 mgd initial phase, and approximately 470 Page 12 acres for the 20-year capacity of 3.0 mgd. The total amount of acreage will vary depending on the physical dimensions of the tract of land. The State regulations require a minimum of 5-day storage pond to hold the effluent during wet or freezing weather. Therefore, a 2.5 million gallon aerated storage pond will be required for the initial phase, and a total of 15 million gallons of holding ponds will be required for ultimate flows. Based on the types of soil in the area, it is extremely unlikely that this quantity of suitable land could be acquired for use as land application sites. For the purposes of this report, it has been assumed that 10,000 LF of effluent transmission lines will be required to transmit the effluent from the WWTP to the Phase. I drip irrigation fields, with an additional 60,000 LF of lines needed for Phase II. The total estimated project cost for Alternative No. 6 is $14,349,200 for the initial phase. A detailed project cost estimate for both phases is provided in Appendix A. As noted earlier, since spray irrigation land and facilities would be greater in cost than drip irrigation facilities, the spray irrigation alternative has been dismissed. 5.

The wastewater flow projections indicate that the initial capacity of the wastewater treatment facility should be 0.5 mgd, with future expansions to 3.0 mgd capacity for the 20-year planning period. Since State regulations require that a plan of action be submitted regarding facility expansion when flows reach 80% of capacity, construction of a 3.0 mgd facility would not require submission of a plan of action until flows reach 2,400,000 gpd, or around the year 2022. This alternative would help preserve the drinking water sources in the Sherrills Ford/Terrell area by decreasing the number of future septic tank systems. The construction of a wastewater collection and treatment system in this area would allow several small wastewater treatment systems to be abandoned, eliminating their discharges to tributary streams of Lake Norman. Consolidation of these treated discharges to one treated discharge to the main channel of the Catawba River is environmentally preferred because the higher stream flow provides a greater capacity to assimilate the treated wastewater.

The design criteria in the report stated that the gravity sewers would be sized to carry the design average daily flow while flowing at a depth of one half the pipe diameter. Gravity lines are considered to be 40 to 50-year facilities; therefore, we suggest that they be designed to flow half full at the 20-year peak flow. 2. The report stated the average unit flow factor for residential wastewater flow as 45 gallons/capita/day. Please justify using a flow factor under 70 gallons/capita/day. 3. The report also stated the average flow factor for industrial and commercial wastewater flow as 195 gallons/employee/day. Please justify this flow factor. Letters of commitment from industries should also be submitted to justify the projected industrial and commercial flow. 4. Provide preliminary design calculations for the 18-inch diameter PVC trunk sewer lines; justify using this size of sewer line. 5. Please provide preliminary design calculations for the 8-inch collector sewer lines along N.C. 10. 6. Please submit a letter from the County Health Department that documents any failures of septic systems in the project area and indicates a need for a central wastewater collection system. 7. Please provide preliminary design calculations for the South Fork pump station and force main. Show the engineering calculations that justify using an 8-inch force main and pump station capacity of 0.7 mgd (470 gpm). Please provide the number of pumps, GPM of each pump, and whether or not standby power will be provided for the pump station. 8. The report indicated that out of 216 homes located near the existing Westside sewer system, only one (1) home has elected to connect to the sewer system. Note that mandatory hookup will be required for the area to be served by the proposed sewer project. 9. Please provide preliminary design calculations for the Startown EIementary School pump station and force main. Note that the report described a 2 or 3-inch diameter force main, while the preliminary construction cost estimates indicated using a 4-inch force main. Typically, a 4-inch diameter force main is the minimum size allowed unless preceded by Camp Dresser & McKee 01 South McDowel Street, Suite 512 Charlotte, North Carolina 28204-2686 Tel: 704 342-4546 Fax: 704 342-2296 November 12,1999 Ms. Shannon Mohr Thornburg Environmental Engineer Non -Discharge Permitting Unit North Carolina Department of Environment and.

No. WQ0017150 Phone: 919-733-5083 ex t. 353 Dear Ms. Thornburg: This letter, on behalf of the City of Newton, is in response to the Non -Discharge Permitting Unit's technical request for additional information related to the review of the Non - Discharge Permit application for the City of Newton's I.S. 321/N.C. 10 Interchange Sewer System Project. The letter was dated October 14, 1999 and requested the clarification of a number of items associated with the application. A copy of the letter is included in Attachment A. The following is the requested information: neral: Please find attached (attachment B) a complete and revised permit application for this project that includes a water classification sheet for the unnamed tributary of Betts Branch, previously omitted. Please note that the portion of the project located west of Startown Road (SR 1005) drains to the South Fork Catawba River, and the portion of the project located east of Startown Road drains to the previously mentionedunnamed tributary to Betts Branch. Please find attached (Attachment C) a copy of documentation verifying the receipt of appropriate nationwide permits/404 Certifications for the project. 401 Certification is pending, but no delays are anticipated. Please find attached (Attachment D) documentation indicating that appropriate soil. erosion and sedimentation control permits have been applied for. Please note that the attached drawings include the requested modifications and will be re -submitted for final approval. 4. Please find attached (Sheets "CD-8 through CD-11") a complete profile of the South Fork Pump Station force main for your review.

Page 2 of 8 of the revised application (Attachment B) includes this modification to reflect initial flows associated with the Startown Elementary School pump station. 2. Page 2 of 8 of the revised application (Attachment B) includes this modification to reflect the correct permit number of the downstream wastewater treatment facility. 3. Please see Attachment E for the revised evaluation of the existing Westside pump station. The following is our response to the comments posed in the letter by bullet item. The second pump at both the South Fork and Startown Elementary School pump stations is provided for redundancy and is not required to deliver design flows. However, if both South Fork pumps are running while the Startown pumps are off, more flow (740 gpm) will be delivered to the existing Westside Pump Station than if one of the South Fork and one of the Startown pumps are running (710 gpm total). Please recall that the original submittal of calculations assumed the latter scenario. The revised calculations attached assume the 740 gpm scenario. At the time that the design calculations were prepared, we were assuming that there were 216 potential single-family home lots tributary to the Westside pump stations as presented on Page 32 of the previously submitted calculations. This number was based on a memorandum prepared by the Director of Public Works for the City of Newton that discussed the costs associated with providing water service to this area (see Attachment E). However, further consideration of this data finds that this memorandum considered other neighborhoods outside the service area of the existing Westside Pump Station, which is able to serve only the Nottingham Subdivision. Furthermore, the memorandum only considered houses that were already built (Le., 48 in the Nottingham Subdivision as of July 30, 1996), of which only one has actually connected to the collection system. There are many empty parcels in this neighborhood. Further evaluation of tax parcel data for the neighborhood indicates that there are 190 total single-family home parcels in the Nottingham Subdivision that could be served by the existing Westside Pump Station (See tax maps in Attachment E). In addition, the parcels may develop as three bedroom homes. Therefore, the average daily unit flow factor for analysis of the Westside Pump Station was increased to 360 gallons per day per Regulation 15A NCAC 2H .0219. Note that significantly more infrastructure must be installed before the entire neighborhood could receive sewer service. The existing gravity sewer system is located along the two streams only. H:.n ewto n4rs3211co r rasptih om brg.wpd CDM Camp Dresser & McKee Ms. Shannon Mohr Thornburg November 12,1999 Page 3 The Westside Pump Station is, in fact, the only wastewater facility that is tributary to the downstream 15-inch diameter trunk sewer. The attached calculations evaluating the performance of the existing Westside Pump Station differ from that previously submitted in the following manner: A.) Both South Fork pumps are assumed to be running while the Startown pumps are off such that the total influent flow from these new systems is 740 gpm (greater than the 710 gpm assumed initially). B.) All 190 parcels tributary to the existing Westside Pump Station have been built upon with three bedroom homes such that the unit flow factor per dwelling unit is 360 gallons per day. Recall that at this time there are only about 50 homes actually built in the subdivision and of those only one has elected to connect to the system. Furthermore it is impossible to predict when or if additional homes will connect to the system. C.) The South Fork pumps are operating on a 23 minute cycle time (see Attachment I) and the dynamic wet well volume is 3,638 gallons. The results of this analysis indicate that the maximum water surface elevation in the existing Westside Pump Station's wet well under this critical hour scenario is 863.32 feet, or 0.56 feet greater than the pump station's current high water alarm. Note, however, that the station is in no danger of overflowing and the surcharge condition would not propagate upstream of the pump station since the invert elevation into the influent structure of the pump station is greater than this elevation at 864.0 feet (See Detail B, Sheet CD-6, of the drawings for further clarification). Therefore, it would be prudent to adjust the high water level alarm at this pump station from its current setting to approximately 864.0 feet. Pumping Station Design: 1. Please find attached (Attachment F) cut -sheets obtained from Flygt's catalog for the pumps around which the contract documents were written (CP-3067 corresponds to the South Fork pump station and CP-3300 corresponds to the Startown Elementary School pump station). Note that other "or equal" pumps are allowed to bid on the project as long as they conform to requirements as detailed in Section 11306 of the technical specifications. 2. The City of Newton owns multiple trucks for electrical power line maintenance that are equipped with steel booms and winches. These trucks are routinely used to lift submersible pumps from their installations for maintenance. il:Lnewtc n\vs3211coryes pUho mbrg.wp d CDM Camp Dresser & McKee Ms. Shannon Mohr Thornburg November 12,1999 Page 4 3. The attached revised drawings include an all-weather roadway to access the proposed Startown Elementary School pump station. 4. Included in Attachment G is the buoyancy calculations as prepared by a structural engineer during his review of the structural elements of the project. Key assumptions in these calculations include that the lift station is fully submerged (i.e., groundwater level and surface water to top of slab, which is the 100-year flood elevation), the wet well is empty, and there are no pumps or piping in the wet well. The calculations also evaluate the alternative scenario for construction of the wet well through the use of a concrete plug for the base. The calculations found that the wet well is not in danger of floating under this scenario. 5. The attached revised drawings include a flap valve in the wet well end of the valve vault drain line to prevent wastewater from backing up into the valve vault. 6. PIease refer to Sections 11306 paragraph 2.07.C.5 and 16191 paragraph 2.01.T for details related to the audible and visual alarm. These features will be included with the pump control panel. The audible and visual alarms are not referenced on the drawings. 7. The intent of the information provided on the application related to this issue was that under the design presented herein, provisions have been made to the electrical systems at the two pump stations to provide connections for portable generators, if needed. The City of Newton does not own portable generators. Please find attached (Attachment H) calculations of available storage time at the two pump stations. Per the attached calculations, there is approximately 12.4 hours of storage available at the South Fork Pump Station under future design conditions. In addition, there is approximately 1.1 hours of storage available at the Startown Elementary School Pump Station (Note that there is additional storage available in the Startown Elementary School system that was not considered in this calculation to provide a safety factor). 8. The attached revised drawings have been modified to reflect this suggestion. 9. Please see the attached calculations (Attachment I) that show that the minimum cycle time of the South Fork Pump Station is 30 minutes or 2 starts per hour. 10. Please refer to the last page of technical specification Section 11306 that provides the desired operating range of the pump to be installed at both the South Fork and Startown Elementary Pump Stations. 11. The basis of design flows used for this project is the Comprehensive Water and Sewer System Analysis (CDM, 1998) prepared for the City of Newton, which identified a set of improvements to provide water and sewer service to new areas in and around the City of Newton. This document also developed flow projections for various planning areas. The 18-inch-diameter gravity trunk sewer is designed to accommodate an ultimate HAriewbanius321 \ca rresplthombrg.wpd CDM Camp Dresser & McKee Ms. Shannon Mohr Thornburg November 12,1999 Page 5 average daily flow rate of approximately 550 gpm. In order for this flow rate to be achieved requires additional sewer to be constructed both upstream of NC10 and on the west side of the South Fork Catawba River. The pump station will initially have only two pumps (i.e., a duplex station), but will be expandable to three pumps (i.e., there will be a vacant slot initially in the wet well). This arrangement minimizes the initial construction cost and allows the city to respond appropriately to actual growth patterns in the drainage basin by either (1) adding a pump, (2) replacing the two existing pumps, or (3) installing three new pumps. An 8-inch-diameter force main was selected based on economic factors as well as to maintain a velocity of greater than 3 fps during initial flows. While the gravity sewer is designed to convey wastewater flows through the 20-year planning horizon, the force main will require an upgrade prior to that time. The city will need to construct a new parallel 10-inch diameter force main to convey the design flows. The minimum design flow (470 gpm) for the pump station (which is the average daily design flow times a factor of 2.5) is based on providing a minimum velocity of 3 fps in the 8-inch diameter force main to keep solids from accumulating in the pipe. This flow rate is to be achieved by one pump. This initial pumping capacity accommodates approximately one-third (Le., 188 gpm) of the ultimate average daily dry weather flow (i.e., 550 gpm) to be conveyed by the South Fork Pump Station in the future. Gravity Sewer and Force Main Designs: 1. Please refer to the attached revised drawings, which call out watertight manhole covers along the South Fork Catawba River. The watertight manhole covers are specified on the manhole detail, in addition to the technical specifications Section 5500 paragraph 2.04.A. 2. Please see the revised permit application (Attachment B) which includes the proper lengths of sewer pipe to be installed under this project. 3. Please refer to the attached revised drawings that have been modified to reflect this change to provide 3 feet of cover between STA 83+80 and 84+25 of the gravity sewer portion of the project. 4. Regulation 15A NCAC 2H .0219 (i) (2) (G) (v) states that the minimum buffer for "Waters classified WS-II, WS-III, B, SA, ORW, HQW, or SB" is 50 feet. Regulation 15A NCAC 2H .0219 (i) (2) (G) (v) states that the minimum buffer for "Any other stream, lake or impoundment" is 10 feet. The South Fork Catawba River is classified as a WS- IV CA water, which is not included in the regulation as one requiring a 50 foot buffer. Therefore, a buffer in excess of 10 feet (and often less than 50 feet) was maintained throughout the selected route of the project. H:\newlon\us321\ grresplthornbrg.wpd CDM Camp Dresser & McKee Ms. Shannon Mohr Thornburg November 12,1999 Page 6 We understand that the interpretation of the 50 foot buffer is based on the following; (a) the WS-IV classification did not exist when Regulation 15A NCAC 2H .0219 (i) (2) (G) (v) was written, (b) a new regulation, not related to sewer design, implemented since this time created the new water supply classification, (c) regulations are time- consuming and challenging to modify, and (d) Regulation 15A NCAC 2H .0219 (i) (2) (G) (v) is now interpreted to indude waters classified as WSIV. Further note that no public notification has been provided indicating the new interpretation of this existing Regulation and the design was completed on the basis of Regulation 15A NCAC 2H .0219 (i) (2) (G) (v) as it currently reads. Note that changes to the route at this stage of the project would require re-routing the sewer into potential wetland areas, re -surveying the route including modifying right-of- way easement plats, and significant associated additional engineering costs. Alternatively, providing ductile iron pipe throughout the force main route will increase significantly the construction cost of the project. The City has therefore taken exception to this comment and as such the revised drawings do not indude either a modified route or the use of ductile iron pipe. 5. Please see comment 4 above. 6. As stated previously under General Comments, Item 1, please find attached (attachment B) a complete and revised permit application for this project that includes a water classification sheet (Class C) for the unnamed tributary of Betts Branch, previously omitted. As required for this water classification, a 10 foot buffer is provided for the proposed force main. 7. Please refer to the attached revised drawings that have been modified to reflect this change to provide sufficient buffer between the gravity sanitary sewer and the storm sewer at STA 100+85. 8. Please refer to the attached revised drawings that have been modified to reflect the locations of drinking water supply wells along the route of the force main. The only wells that were found to be near the route of the force main were in the Wyoming Street neighborhood as shown on sheet C-12. 9. Section 02610 (Pipeline Testing and Cleaning) has been modified to include a maximum allowable leakage rate of 100 gallons per day per inch diameter per mile installed. 10. The technical specifications have been amended to mandate that pressure and leakage testing for force mains shall be in accordance with AWWA C600 for ductile iron pipe and AWWA C605 for PVC pipe.

NCDENR NORTH CAROUNA DEPARTMENT OF ENVIRONMENT AND NAMIRAE RESOURCES Subject: Application No. WQ0017150 Additional information Request US 321/NC 10 Interchange Sewer System Sewer -Public Catawba County The Non -Discharge Permitting Unit has completed a preliminary engineering review of the subject application. Additional information is required before we can continue our review. Please address the following items no later than November 15, 1999: General: 1) Only one Page 5 of 8 of the application form was submitted with this application package. Please note that a downslope water classification sheet must be provided for each pumping station to be permitted. Therefore, please provide a second Page 5 of 8 for the Startown Road School Pump Station, or otherwise provide information that confirms that downslope water classification for the South Fork Pump Station is applicable. 2) Please verify that the appropriate nationwide permits/401/404 Certifications have been applied for and/or received for the various stream crossings and wetland impacts throughout this project. 3) Please verify that the appropriate soil erosion and sedimentation control permit have been applied for and/or received for this project. 4) Regulation 15A NCAC 2H .0205 (d) (4) (B) requires that plan and profile be provided for all force mains. Note that the submitted drawings only contain a plan view and selected detailed profile views of the South Fork Pump Station force main. Although a general note regarding minimum cover over this force main was provided, the Division of Water Quality (Division) uses the profile views to verify the minimum cover, maintenance of State -required vertical buffers, proper placement of air -release valves, and the pumping station design calculations. For these reasons, please amend the drawings to include complete profile drawings for all sewers proposed by this project. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone 919-733-5083 FAX 919-715-6048 An Equal Opportunity Affirmative Action Employer 50% recycled! 10% post -consumer paper Wastewater Flows: 1) Item III. 6. on Page 2 of 8 of the submitted application farm states that zero flow will be generated by this project in the short term. Specifically, flow will be allocated as sewer extensions are made to the proposed trunk line. It is apparent, however, that the flow from the Startown Road School will be made tributary to the system almost immediately. Therefore, please amend Page 2 of 8 ((i.e., signed, sealed, and dated by the North Carolina -licensed professional engineer) with the expected daily design flow from this facility. 2) Item IV. 2. a. on Page 2 of 8 of the submitted application form states that the .permit number for the wastewater treatment facility to receive the wastewater is WQ0003902. The Division's records show that this is the permit for the City of Newton's residuals Iand application program. Please provide an amended Page 2 of 8 (i.e., signed, sealed, and dated by the North Carolina -licensed professional engineer) that provides the correct information. 3) The downstream sewers' evaluation provided in the engineering calculations is one of the most comprehensive that this reviewer has seen. However, please clarify the following issues: ♦ From review of the engineering calculations, it appears as if the peak flow to the Westside Pump Station would be equivalent to 740 gallons per minute (i.e., initial case with two pumps operating in the South Fork Pump Station and the Startown Road School Pump Station off). Please amend the evaluation accordingly. ♦ Please clarify whether there are 216 or 204 homes previously permitted to tie into the Westside Pump Station (i.e., see discrepancy between Page 32 and Page 35 of engineering. calculations). ♦ The daily design flow for the 204 homes previously permitted to tie into the Westside Pump Station was assumed to be 240 gallons per day. Please confirm that these were, in fact, planned as two -bedroom homes and not with three bedrooms. + Please clarify whether or not the Westside Pump Station is the only wastewater facility that is tributary to the 15-inch gravity sewer. Pumping Station Design: 1) Please submit cut -sheets detailing the dimensions and minimum installation requirements (i.e., minimum wet well size, minimum deadman's float level, minimum access hatch sizes, etc.) for the final pump.selected for both the South Fork Pump Station and the Startown Road School Pump Station. 2) Please clarify how the pumps at both the South Fork Pump Station and the Startown Road School Pump Station will be removed from their respective wet wells for maintenance, repair, and/or replacement. Pumping Station Design (continued): 3) Regulation 15A NCAC 2H .0219 (h) (8) requires that an all-weather roadway be provided to all pumping station sites. The road design for the South Fork Pump Station is obvious in the submitted drawings; however, the Division could not discern that a road is proposed at the Startown Road School Pump Station as well. Please amend the drawings as necessary, and submit the revised drawings for the Division's review. 4) Please provide buoyancy calculations for both the South Fork Pump Station and the Startown Road School Pump Station, assuming complete submersion and ignoring the weight of the pumps and any residual wastewater in the wet wells. Ensure that the calculations match with what is provided on the submitted drawings (i.e., same amount of concrete, etc.). 5) Please provide a flap valve or some other type of mechanism to prevent accumulated wastewater from backing up from the wet wells into the valve vaults of both the South Fork Pump Station and the Startown Road School Pump Station. 6) Neither Sheet E-1/Sheet E-2 nor Section 11306 (Submersible Wastewater Pumps) • specifies that audible and visual alarms are to be provided at the South Fork Pump Station and the Startown Road School Pump Station. Note that these types of alarms are required at all pumping stations, per Regulation 15A NCAC 2H .0219 (h) (5). Please amend the drawings and specifications accordingly for the Division's review. 7) The submitted application form and drawings indicate that a portable generator is to be at both pumping stations in the event of a power failure. Please provide the City's contingency plan for handling such a situation. Specifically, this plan should clarify how many pumping stations the stand --by generators are going to serve, the anticipated response time, notification procedures, and responsible personnel. Note that additional wet well storage should be designed at the proposed pumping stations, if applicable. 8) The Division suggests placing the -high water alarm float at the same elevation level or below the Iag pump on float in the pumping station wet well. This setting will indicate a failure of the lead pump while the lag pump is still available. Please consider amending the proposed pumping station design to provide this additional guarantee against failure. 9) As stipulated by Regulation 15A NCAC 2H .0219 (h) (2), pump on and off floats should be set such that between two and eight pumping cycles per hour are affected at pumping stations. Note that the cycles per hour at the South Fork Pump Station do not appear to meet this criterion for any of the scenarios evaluated in the engineering calculations. Please amend the float settings accordingly, and submit revised drawing sheets to the Division for review. 10) PIease note that Section 11306 (Submersible Wastewater Pumps) of the submitted specifications does not specify the desired operating/design points of the pumps to be installed at the South Fork Pump Station and the Startown Road School Pump Station. Consider clarifying this information in the design documents for the installing contractor. Pumping Station Design (continued): 11) Regulation 15A NCAC 2H .0219 (h) (2) requires that pumping stations should be designed such that one pump is capable of conveying 2.5 times the average daily flow. The engineering calculations seem to indicate that the average daily flow to the South Fork Pump Station is 1.05 cubic feet per second (Le., equivalent to approximately 471 gallons per minute). Item V_ 5. on Page 4B of 8 of the submitted application form lists the pump size at this location to be 470 gallons per minute minimum. Please explain the basis for this pump station's sizing. Gravity Sewer and Force Main Designs: 1) Watertight manhole covers are not called out for any of the manholes that will be affected by the 100-year flood. In addition, no detail was provided for said watertight manholes. Please amend the profile and detail sheets of the submitted drawings accordingly. 2) It does not appear as if the 95 linear feet of eight -inch gravity sewer to be installed at the Startown Road School was taken into account in Item IV. 3. on Page 2 of 8.of the submitted permit application. In addition, the 12 linear feet of 12-inch gravity sewer near the Westside Pump Station was also missing from this take -off. In addition, please note that, according to the submitted drawings, approximately 13,400 linear feet of eight -inch force main is proposed for installation. The submitted engineering calculations as well as Item V. 9. on Page 5B of 8 of the submitted application form list the force main as being only 12,000 feet long_ PIease clarify, and provide an amended pages of the application form (i.e., signed, sealed, and dated by the North Carolina -licensed professional engineer) as necessary. 3) ReguIation 15A NCAC 2H .0219 (i) (2) (H) requires that a minimum of three feet of cover must be provided over all sewers unless a ferrous material is used for sewer construction. The gravity sewer design between STA 83+80 and STA 84+25 does not appear to meet this criterion. Please amend the gravity sewer design accordingly, and submit the revised drawing sheet for the Division's review. 4) Note that the Division requires that a 50-foot horizontal buffer must be maintained between sewers and waters classified as WS (i.e., except watersheds classified as WS-I, in which sewer construction is prohibited). If this buffer cannot be met, ferrous material with joints equivalent to water main standards may be used for sewer construction in accordance with Regulation 15A NCAC 2H .0219 (i) (2) (G) (xii). The Catawba River is classified as a WS-IV CA surface water; therefore, the gravity sewer design between STA 35+45 and STA 39+70 does not appear to comply with these criteria. In addition, must of South Fork Pump Station's force main route also appears to violate this State -required buffer. Please amend the gravity sewer and force main designs accordingly, and resubmit all amended drawing sheets for the Division's review. 5) In addition to the comment above, the watertight steel sewer encasement pipes at all stream crossings need to be extended for 50 linear feet either side of the crossings. Please amend the design for all stream crossings of the proposed gravity sewers and force mains accordingly. Gravity Sewer and Force Main Designs feontinned): 6) Please provide the surface water classification for the Unnamed Tributary of Betts Branch. Ensure that State -required buffers, as stipulated by Regulation 15A NCAC 2H .0219 (i) (2) (G) are met by the proposed design, and resubmit all amended drawing sheets for the _ Division's review. 7) The crossing of the proposed gravity sewer with a storm sewer at STA 100+85 does not appear to meet the minimum buffer required by Regulation 15A NCAC 2H .0219 (i) (2) (G) (i). PIease amend the design, and submit the revised drawing sheet for the Division's review. 8) Please provide the location of the private wells, mentioned in Note No. 4 on Sheet C-12 of the submitted drawings, so that the Division may verify that the proposed design is in compliance with Regulation I5A NCAC 2H .0219 (i) (2) (G) (iv) and Regulation, 15A NCAC 2H .0219 (i) (2) (G) (xii). 9) Regulation 15A NCAC 2H .0219 (i) (2) (D) states that the maximum infiltration rate for sewers shall be limited to 100 gallons per day per inch diameter per mile of pipe installed. Page 2 and Page 3 of Section 02610 (Pipeline Testing and Cleaning) provides guidance for infiltration and exfiltration testing for gravity sewer pipe installation. Note that the specifications do not provide a maximum leakage rate for the infiltration test. In addition, the maximum allowable Ieakage rate for the exfiltration test calculates out to be 100.32 gallons per day per inch diameter per mile of pipe installed. Please amend this section of the specifications to comply with the State's minimum standards. 10) In addition to the comment above, please amend the force main testing specifications to include a maximum allowable leakage rate. Please reference the subject permit application number when providing the requested information. All revised information, including letters, calculations, drawings, and specifications, should be signed, sealed, and submitted in triplicate to my attention at the address above. Please note that failure to provide this additional information on or before the above requested date can result in your application being returned as incomplete. - If you have any questions regarding this request, please call me at (919) 733-5083, extension 353.

Stowe, City Engineer Subject:. Westside Subdivision Waterline C st Estimates Date: July 30,1996 As you requested, I have completed cost estimates for each of the five subdivisions in the Westside of Newton. The overall cost associated with the design and construction of all of the waterlines is approximately $400,000. The Val potential increase in customers is 216. This calculates,to approximately $1,850 per potential customer. I did not include taps in the cost of the water.ftes because the tap cost will depend on nc�- number of participInts, who installs the taps, and tb:.• a✓tuai east of the taps. Based on the resi:ua se from citizens regarding the waterline that we are const u : ng through Nottingham currently, .[ believe that we ce A expect between. 50 and 75 percen participation in an initial tap offering. The following Table breaks down the cost 1.ne total,. potential customers for each watenhue: Subdivision Cost Estimate • Potential Customers Bettes Brooke $50,000 30 Dixie Park $48,000 18 Nottingl i;m $92,000 •48 Starmot'ii Village $115,000 Westsic Hills $95,000 Total $400,000 'F,3 .6.0• 216 These costs include design, surveying, comi iicti ..'n, and 15% contingency. Several advantages to serving these areas with 1 ti ater include: • Increased fire protection k creased water i Gage and revenue ▪ Cc.mpletion of a loop through Stain r s ant Village, Nottingham, and Bettes Bro-:)k. I have h;!': many calls from residents in thEasking when water service be availably:, 'a them.

By providing, a loop through Starmount Village, Nottingham, and Bettes Brook the water quality at Startown School should be better.

Additional information is required before we can continue our review. Please address the following items no later than November 15, 1999: General: 1) Only one Page 5 of 8 of the application form was submitted with this application package. Please note that a downslope water classification sheet must be provided for each pumping station to be permitted. Therefore, please provide a second Page 5 of 8 for the Startown Road School Pump Station, or otherwise provide information that confirms that downslope water classification for the South Fork Pump Station is applicable. 2) PIease verify that the appropriate nationwide permits/401/404 Certifications have been applied for and/or received for the various stream crossings and wetland impacts throughout this project. 3) Please verify that the appropriate soil erosion and sedimentation control permit have been applied for and/or received for this project. 4) Regulation 15A NCAC 2H .0205 (d) (4) (B) requires that plan and profile be provided for all force mains. Note that the submitted drawings only contain a plan view and selected detailed profile views of the South Fork Pump Station force main. Although a general note regarding minimum cover over this force main was provided, the Division of Water Quality (Division) uses the profile views to verify the minimum cover, maintenance of State -required vertical buffers, proper placement of air -release valves, and the pumping station design calculations. For these reasons, please amend the drawings to include complete profile drawings for all sewers proposed by this project. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone 919-733-5083 FAX 919-715-6048 An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper Wastewater Flows: 1) Item III. 6. on Page 2 of 8 of the submitted application form states that zero flow will be generated by this project in the short term. Specifically, flow will be allocated as sewer extensions are made to the proposed trunk Iine. It is apparent, however, that the flow from the Startown Road School will be made tributary to the system almost immediately. Therefore, please amend Page 2 of 8 ((i.e., signed, sealed, and dated by the North Carolina -licensed professional engineer) with the expected daily design flow from this facility. 2) Item IV. 2. a. on Page 2 of 8 of the submitted application form states that the permit number for the wastewater treatment facility to receive the wastewater is WQ0003902. The Division's records show that this is the permit for the City of Newton's residuals land application program. Please provide an amended Page 2 of 8 (i.e., signed, sealed, and dated by the North Carolina -licensed professional engineer) that provides the correct information. 3) The downstream sewers' evaluation provided in the engineering calculations is one of the most comprehensive that this reviewer has seen. However, please clarify the following issues: ♦ From review of the engineering calculations, it appears as if the peak flow to the Westside Pump Station would be equivalent to 740 gallons per minute (i.e., initial case with two pumps operating in the South Fork Pump Station and the Startown Road School Pump Station off). Please amend the evaluation accordingly. • Please clarify whether there are 216 or 204 homes previously permitted to tie into the Westside Pump Station (i.e., see discrepancy between Page 32 and Page 35 of engineering calculations). • The daily design flow for the 204 homes previously permitted to tie into the Westside Pump Station was assumed to be 240 gallons per day. Please confirm that these were, in fact, planned as two -bedroom homes and not with three bedrooms. ♦ Please clarify whether or not the Westside Pump Station is the only wastewater facility that is tributary to the 15-inch gravity sewer. Pumping Station Design: 1) Please submit cut -sheets detailing the dimensions and minimum installation requirements (i.e., minimum wet well size, minimum deadman's float level, minimum access hatch sizes, etc.) for the final pump selected for both the South Fork Pump Station and the Startown Road School Pump Station. 2) Please clarify how the pumps at both the South Fork Pump Station and the Startown Road School Pump Station will be removed from their respective wet wells for maintenance, repair, and/or replacement. Pumping Station Design (continued): 3) Regulation 15A NCAC 2H .0219 (h) (8) requires that an all-weather roadway be provided to all pumping station sites. The road design for the South Fork Pump Station is obvious in the submitted drawings; however, the Division could not discern that a road is proposed at the Startown Road School Pump Station as well. Please amend the drawings as necessary, and submit the revised drawings for the Division's review. 4) Please provide buoyancy calculations for both the South Fork Pump Station and the Startown Road School Pump Station, assuming complete submersion and ignoring the weight of the pumps and any residual wastewater in the wet wells. Ensure that the calculations match with what is provided on the submitted drawings (i.e., same amount of concrete, etc.). 5) Please provide a flap valve or some other type of mechanism to prevent accumulated wastewater from backing up from the wet wells into the valve vaults of both the South Fork Pump Station and the Startown Road School Pump Station. 6) Neither Sheet E-1/Sheet E-2 nor Section 11306 (Submersible Wastewater Pumps) specifies that audible and visual alarms are to be provided at the South Fork Pump Station and the Startown Road School Pump Station. Note that these types of alarms are required at all pumping stations, per Regulation 15A NCAC 2H .0219 (h) (5). Please amend the drawings and specifications accordingly for the Division's review. 7) The submitted application form and drawings indicate that a portable generator is to be at both pumping stations in the event of a power failure. Please provide the City's contingency plan for handling such a situation. Specifically, this plan should clarify how many pumping stations the stand-by generators are going to serve, the anticipated response time, notification procedures, and responsible personnel. Note that additional wet well storage should be designed at the proposed pumping stations, if applicable. 8) The Division suggests placing the high water alarm float at the same elevation level or below the lag pump on float in the pumping station wet well. This setting will indicate a failure of the lead pump while the lag pump is still available. Please consider amending the proposed pumping station design to provide this additional guarantee against failure. 9) As stipulated by Regulation 15A NCAC 2H .0219 (h) (2), pump on and off floats should be set such that between two and eight pumping cycles per hour are affected at pumping stations. Note that the cycles per hour at the South Fork Pump Station do not appear to meet this criterion for any of the scenarios evaluated in the engineering calculations. Please amend the float settings accordingly, and submit revised drawing sheets to the Division for review. 10) Please note that Section 11306 (Submersible Wastewater Pumps) of the submitted specifications does not specify the desired operating/design points of the pumps to be installed at the South Fork Pump Station and the Startown Road School Pump Station. Consider clarifying this information in the design documents for the installing contractor. Pumping Station Design (continued): 11) Regulation 15A NCAC 2H .0219 (h) (2) requires that pumping stations should be designed such that one pump is capable of conveying 2.5 times the average daily flow. The engineering calculations seem to indicate that the average daily flow to the South Fork Pump Station is 1.05 cubic feet per second (i.e., equivalent to approximately 471 gallons per minute). Item V. 5. on Page 4B of 8 of the submitted application form lists the pump size at this location to be 470 gallons per minute minimum. Please explain the basis for this pump station's sizing. Gravity Sewer and Force Main Designs: 1) Watertight manhole covers are not called out for any of the manholes that will be affected by the 100-year flood. In addition, no detail was provided for said watertight manholes. Please amend the profile and detail sheets of the submitted drawings accordingly. 2) It does not appear as if the 95 linear feet of eight -inch gravity sewer to be installed at the Startown Road School was taken into account in Item IV. 3. on Page 2 of 8. of the submitted permit application. In addition, the 12 linear feet of 12-inch gravity sewer near the Westside Pump Station was also missing from this take -off. In addition, please note that, according to the submitted drawings, approximately 13,400 linear feet of eight -inch force main is proposed for installation. The submitted engineering calculations as well as Item V. 9. on Page 5B of 8 of the submitted application form list the force main a§ being only 12,000 feet long. PIease clarify, and provide an amended pages of the application form (i.e., signed, sealed, and dated by the North Carolina -licensed professional engineer) as necessary. 3) Regulation I5A NCAC 2H .0219 (i) (2) (H) requires that a minimum of three feet of cover must be provided over all sewers unless a ferrous material is used for sewer construction. The gravity sewer design between STA 83+80 and STA 84+25 does not appear to meet this criterion. Please amend the gravity sewer design accordingly, and submit the revised drawing sheet for the Division's review. 4) Note that the Division requires that a 50-foot horizontal buffer must be maintained between sewers and waters classified as WS (i.e., except watersheds classified as WS-I, in which sewer construction is prohibited). If this buffer cannot be met, ferrous material with joints equivalent to water main standards may be used for sewer construction in accordance with Regulation 15A NCAC 2H .0219 (i) (2) (G) (xii). The Catawba River is classified as a WS-IV CA surface water; therefore, the gravity sewer design between STA 35+45 and STA 39+70 does not appear to comply with these criteria. In addition, must of South Fork Pump Station's force main route also appears to violate this State -required buffer. Please amend the gravity sewer and force main designs accordingly, and resubmit all amended drawing sheets for the Division's review_ 5) In addition to the comment above, the watertight steel sewer encasement pipes at all stream crossings need to be extended for 50 linear feet either side of the crossings. Please amend the design for all stream crossings of the proposed gravity sewers and force mains accordingly. Gravity Sewer and Force Main Designs (continued): 6) Please provide the surface water classification for the Unnamed Tributary of Betts Branch. Ensure that State -required buffers, as stipulated by Regulation 15A NCAC 2H .0219 (i) (2) (G) are met by the proposed design,. and resubmit all amended drawing sheets for the Division's review. 7) The crossing of the proposed gravity sewer with a storm sewer at STA 100+85 does not appear to meet the minimum butler required by Regulation 15A NCAC 2H .0219 (i) (2) (G) (i). Please amend the design, and submit the revised drawing sheet for the Division's review. 8) Please provide the location of the private wells, mentioned in Note No, 4 on Sheet C-12 of the submitted drawings, so that the Division may verify that the proposed design is in compliance with Regulation 15A NCAC 2H .0219 (i) (2) (G) (iv) and Regulation 15A NCAC 2H ,0219 (i) (2) (G) (xii). 9) Regulation 15A NCAC 2H ,0219 (i) (2) (D) states that the maximum infiltration rate for sewers shall be limited to 100 gallons per day per inch diameter per mile of pipe installed. Page 2 and Page 3 of Section 02610 (Pipeline Testing and Cleaning) provides guidance for infiltration and exfiltration testing for gravity sewer pipe installation Note that the specifications do not provide a maximum leakage rate for the infiltration test. In addition, the maximum allowable leakage rate for the exfiltration test calculates out to be 100.32 gallons per day per inch diameter per mile of pipe installed, Please amend this section of the specifications to comply with the State's minimum standards. 10) In addition to the comment above, please amend the force main testing specifications to include a maximum allowable leakage rate. Please reference the subject permit application number when providing the requested information. All revised information, including letters, calculations, drawings, and specifications, should be signed, sealed, and submitted in triplicate to my attention at the address above. Please note that failure to provide this additional information on or before the above requested date can result in your application being returned as incomplete. If you have any questions regarding this request, please call me at (919) 733-5083, extension 3. Thank you in advance for your cooperation and timely response.
