Potential open. Cut or winching of pipeline across the Nanse River was not addressed in the response. We continue to recommend that pipeline crossing the Neuse River be installed by directional drilling underneath the riverbed to avoid adverse impacts to aquatic resources. Directional drilling could be done at apy time of the year. If directional drilling is not possible for some justifiable reason,. open cut construction trust avoid the Mauch 1 to October 1 period of anadromous striped bass (Mom ne saxatilis) and American shad (Aiosa sapidrssima) spawning and out migration in order to miztimize impacts to aquatic resources. 2.

It is our understauding the County now proposes to use open cut construction at this stream crossing, Swift Creek is just dovmstream of the project, however, and this stream does have records of dwarf wedgemussel as well as numerous other listed species. Elevated turbidity generated by an open cut on the tributary could very well impact endangered and threatened mussels downstream in Swift Creek. Consequently, we recommend that the County reveCt to its original deoision to use directional drilling at this stream crossing. We £iirthe r recommend that all fuhn stream crossings in the very sensitive Swift Deek watershed be done using directional drilling. Our cumulative and secondary impacts guidance recommends 200 ft. stream buffers or the entire 100 year floodpIaiu where listed species occur, but we acknowledge this guidance came out after the subject project was iriidated. Our interpretation oi'the response is that the project is within Tohnston County's Environmentally Sensitive Overlay District (ESOD) that requires 100 it. buffers.

NHP is still concerned about impacts to sensitive and rare species. Rare aquatic species likely to be impacted by this project include the federal and state endangered dwarf wedgemussel (Alasmidonta heterodon); the federal, species of special concern and state endangered Yellow lance (Elliptio laneeolata), Atlantic pigtoe (Fusconaia masoni), and Green floater (Lasmigona subviridis); the federal species of special concern and state significantly rare Pinewoods shiner (Lythrurus matulinus); the state threatened Triangle floater (Alasmidonta undulara), Roanoke slabshell (Elliptio roanokensis), Creeper (Strophitus undulates), Eastern lampmussel (Lamp,sihs radiata), and Least brook lamprey (Lampetra aepyptera); the state species of special concern Notched rainbow (lrllosa constricta), Cape Fear spike (Elliptio marsupiobesa), Neuse River waterdog (Necturus lewisz), Carolina madtom (Noturus furiosus), and the North Carolina spiny crayfish (Orconectes carolinensis). At this time, NHP would like to raise some issues with the Threatened and Endangered Species Technical Report prepared by S&ME in February 2004. The information presented in the report on the federally endangered Tar spinymussel (Elliptio steinstansana) is incorrect. Our previous comments refer to Swift Creek of the Neuse River basin in Johnston County. The information reported by S&ME refers to the Tar River basin population. The FWS Recovery Plan for the Tar spinymussel was published in 1992, prior to the discovery of the Tar spinymussel in the Neuse River basin. In 1998, biologists with the NC Wildlife Resources Commission (WRC) confirmed the existence of the Tar spinymussel in the Little River in Johnston County. Although the Tar spinymussel has not been found in Swift Creek of the Neuse River basin, several of the species 1601 Mail Service Center, Raleigh, North Carolina 27699-1601 teCarolinPhone: 919-733-49841 FAX: 919-715-30601 Intemet: www.enr.state nc.us/ENRI allr� An Equal Oppartun41 A4rmabe Action Employer - 50 % Recycled 110 % Post Consumer Paper 0 0 11/19/2004 17:27 9197153060 NCDENR PAGE 03/05 associates have been found in this portion of Swift Creek, and we believe it is possible for the Tar spinymussel to exist in this portion of the Neuse River basin. We therefore agree with the biological conclusion that Suitable Habitat is Present for both the federally endangered Dwarf wedgemussel and the Tar spinymussel, and we encourage intensive surveys at all crossing locations. In response to earlier correspondence, the County states that "if no species are present, the County proposes to cross the stream by open cut method in lieu of the directional drilling method" (p. 5). NHP strongly discourages the open cut .method because of the direct impacts to sensitive species. Although the Josephine Road Force Main mussel survey did not locate mussels at the site, this crossing is very close to the confluence of the unnamed tributary to Swift Creek, a nationally signficant aquatic habitat where records exist for several of the rare and endangered species mentioned above, including the federally endangered Dwarf wedgemussel. The direct impacts associated with open trenching (especially turbidity) will likely impact the rare species in Swift Creek. In. accordance with the biological conclusion, Suitable Habitat is Present, and NHP strongly encourages directional boring for all streams crossed in the project area. Since directional drilling greatly minimizes impacts, surveys for aquatic species may not be needed at crossings where drilling is used. Furthermore, NHP recommends that all future crossings in the Swift Creek watershed of the Neuse River basin be done using directional boring. If the Neuse River crossing cannot be directionally bored, NHP strongly encourages the avoidance of construction during 1Vlarch I" through October t" to allow for spawning and migration of anadromous fish species. NHP would also like to emphasize the importance of wide buffers because of the likelihood of this project affecting the federally endangered Dwarf wedgemussel. We do not think the buffers from the Stormwater Management Ordinance are sufficient to protect endangered aquatic species. NHP requests consideration of a minimum 200-font buffer for perennial streams and a 100-foot buffer for intermittent streams to maintain the integrity of the buffer or the full extent of the 100-year floodplain, in accordance with WRC's guidelines. Given these concerns, NHP cannot concur with the finding of no significant impact for this project. Please let me know if I can provide more information. The North Carolina Natural Heritage Program looks forward to a collaborative effort to help protect the State's natural diversity.

Summary, Conclusion & Recommendations: The Cleveland Area Wastewater Diversion Facilities Improvements (CAWWDFI) were planned and presented in detail in Chapters 4 and 5 of the Johnston County/Smithfield-Selma 201 Facilities Plan Amendment No. 3. The original plan provided for construction of a wastewater flow equalization and pumping facility on the Old Cleveland School campus on SR 1010, in addition to wastewater force main improvements to direct flow into the equalization site and a 12" force main from the site to a new transfer wastewater pump station in the Johnston County Landfill. The landfill station will deliver wastewater through a 12" force main to the Central Wastewater Treatment Plant. Please refer to Figure 5.1 in Amendment No. 3. Since the 201 Facilities Plan Amendment No. 3 was approved and the FONSI published, certain changes have occurred. Due to a problem in communication, another County Department authorized the construction of other facilities on the site of the proposed equalization and pump station. Sufficient area is not available on the County -owned Old Cleveland School site to construct the proposed facilities with the necessary road access and perimeter buffers. An alternative, essentially comparable plan has been conceived which involves effective use of existing gravity sewers, a force main segment, and a local pump station which have been constructed and commissioned since the original CAWWDFI program was drafted. The principal physical differences, in addition to alternative pump station and equalization basin sites, is deferring construction of the flow equalization basin and appurtenances until the second 10 year phase of the 201 planning period. Please refer to Figure 5.1(Revised) which is attached. The total present worth cost of the original program and revised program are virtually equal. No adjustments are required in the user fees projected in 201 Amendment No. 3. All new facilities, with the exception of the future equalization tank site, are located within the original environmental corridor. All facilities within the first phase of construction lie within existing utility easements and public road rights -of -way. Construction of the alternative CAWWDFI program, as presented herein, is recommended. B. Project Description: k Page 1 of 4 x Fou The Johnston County Utilities Department engineering staff has conceived an alternative plan for the CAWWDFI. Construction of pumping and equalization facilities and tributary force mains will be accomplished in two phases. The first phase will serve the area for ten years. The second phase will consist of project facility additions to accommodate projected flows over the second ten year phase of the 201 Amendment No. 3 planning period. Please refer to Figure 5.1A for a schematic of the existing wastewater collection and pumping facilities in the area for background information. The first phase of improvements will consist of: Upgrading the County's existing Broadmoor wastewater pump station to serve as the principal forward flow pumping facility. Improvements include two 700 gpm pumps, a fine screen, a magnetic flow meter, and a magnesium hydroxide feed system 2. Siting (but not construction) of an equalization tank and associated piping. The site will be situated in the vicinity of the Broadmoor wastewater pumping station. 3. Installation of approximately 1,700 of 8" force main connecting segment from the existing 6" force main on Cornwallis Road to an existing 8" gravity sewer line on Cambridge Elm Drive in the Weston Woods Development. (The 8" gravity sewer line is tributary to the Broadmoor pump station.) 4. Modification of existing 6" and 4" force main piping in the vicinity of the existing Cleveland K-5 School wastewater pump station. The modifications will facilitate the Cleveland K-5 station pumping through an existing 4" force main to the existing Old Cleveland School wastewater pump station, and pumping through an existing 6" force main and the proposed 8" force main segment to the 8" gravity sewer line in the Weston Woods Development, consistent with Item #3 above. 5. Modifications to existing 4" and 8" force main piping in the vicinity of the Old Cleveland School wastewater pump station, and installation of a diversion connection between the existing 8" force main on Broadmoor Way and the existing 8" gravity sewer line on Broadmoor Way which is tributary to the Broadmoor pump station. These modifications will allow wastewater pumped from the Cleveland K-5 wastewater pump station through the existing 4" force main to be conveyed to the Broadmoor pump station using a portion of an existing 8" force main; and additionally, diversion of wastewater from the 8" force main on NC 42 to the Broadmoor wastewater pump station in the second phase of the program. 6. Installation of approximately 2,2001.f. of 12" force main from the existing 8" force main near the manhole/force main connection on Broadmoor Way to SR 1010. Please refer to Figure 51B which is a schematic of the proposed first phase improvements and to Figure 5.1(Revised) which is a vicinity map illustrating the improvements. The second phase of construction will consist of: Page 2 of 4 O O 1. Construction of a 150,000 gallon aerated equalization tank and related connecting piping, valves, and controls. 2. Construction of a new 8" force main from the existing 8" force main on NC 42 to the Broadmoor wastewater pump station, approximately 27,000 l.f in length. Please refer to Figure 5.1C which is a schematic of the proposed first and second phase improvements and to Figure 5.1 (Revised) for a vicinity map of all improvements. C. Justification: A parking lot and soccer field have been constructed on the Old Cleveland Middle School site in the location of the planned Cleveland area wastewater equalization and pumping facilities. Sufficient area is not available on site for construction of the originally proposed facilities with suitable road access and perimeter buffers. Requiring the local community athletic association to remove the recreation facilities and construct on another private site would cause significant financial hardship and possibly public outrage. The alternative program is functionally equivalent to the original program and can be constructed and operated for virtually the same cost. D. Cost Effectiveness: The estimated total project cost for the first phase of improvements is $782,000 and for the second phase of improvements, $1,105,000. Detailed breakdowns of the costs are presented in Table 4.9 (Revised). The capital costs may be compared to the capital cost of the corresponding elements under the original 20-year program presented in the 201 Facilities Plan Amendment No. 3 in the amount of $1,235,000. By postponing construction of the flow equalization tank and the 27,000 l.f., 8" force main segment, annual OM&R costs over the twenty year planning period are slightly reduced in comparison to the original program. The present worth cost of the proposed elements is $1,988,000. The present worth cost of the corresponding elements of the original project is $1,981,000. Present worth cost calculations are included as an attachment to this engineering amendment. User Fee Anal: The changes in scope for the CAWWDFI will result in essentially the same total annual cost as for the original program. Thus, the impact on user charges is insignificant. No further user charge adjustments will be necessary for the revised CAWWDFI program. Page 3 of 4 X x AMEM=w r- Environmental Corridor: All improvements in the first phase of the CAWWDFI are located clearly within the original environmental corridor. Further, all construction lies within the existing County -owned land parcel, existing utility easements, and public road rights -of -way. All construction elements are located within previously, and recently disturbed areas. With the exception of the flow equalization tank, all improvements in the second phase of the CAWWDFI are also located within the original environmental corridor. With the exception of the future flow equalization tank site, all construction sites were environmentally assessed and included under the original FONSL The 15 acre flow equalization tank and access drive site will be located outside flood plains, wetlands, and riparian buffers in a recent growth, hardwood forest. An access road between the existing Broadmoor pump station and the equalization tank site will cross a small intermittent stream and a riparian buffer encroachment permit will be required. A total of approximately 0.75 acres of clearing will be required. Improvements will not directly affect any threatened or endangered plant or animal species, prime or unique agricultural lands, or areas of archaeological or historic value. No additional wastewater pumping or transmission capacity will be provided by the alternative CAWWDFI program beyond the capacity of the original program. Thus, nohanges in secondary and cumulative impacts will result.

Summary, Conclusions, and Recommendations More storage capacity is needed at the Selma Equalization & Pumping Facility to handle peak wet weather flow events and to prevent bypasses and overflows of untreated wastewater. Constructing a 1.5 MG pre -stressed concrete tank and adding a second magnetic meter to measure flow diverted to the basins will meet that need. Adding storage volume with a cylindrical concrete tank is the most cost effective alternative available to prevent sanitary sewer overflows. The estimated project cost is $695,000. All work is located within a previously disturbed site owned by the County, a former wastewater treatment plant converted to a pumping and equalization facility. An environmental assessment was previously completed under a State Clean Water Bond Grant project in 1999-2000. Construction of the improvements detailed herein is recommended. B. Project Description The proposed project is intended to increase the flow equalization storage capacity of the Selma Equalization & Pumping Facility. It includes the construction of a 1.5 MG pre- EO w stressed, open top concrete storage tank, water cannons for tank wash down, interconnecting piping and a magnetic flow meter. The proposed work is shown as Figure 5-2A of the attached exhibits. All proposed work would be executed on the existing site. The project is estimated to cost approximately $695,000. A detailed cost opinion is included as new Exhibit 4-15. C. Justification All wastewater spills in the Johnston County collection system during the past 2'/2 years have occurred in the Buffalo Creek interceptor area of the Central Johnston County Regional Wastewater Facilities (Exhibit 4-14). Under current conditions, significant to extreme rainfall events force the staff of Johnston County Department of Utilities to choose whether to overflow the Selma Equalization and Pumping Facility or the downstream Buffalo Creek Pumping station. The Buffalo Creek wastewater transmission/interceptor system cannot hydraulically accommodate the peak wet weather flows from the Selma service area. While Selma has taken measures to repair its infiltration/inflow problems (appendix D of Amendment No. 3), the anticipated positive effects have not materialized, at least as far as wet weather flows into the Selma Pumping and Equalization Facility are concerned. In fact, an increase in hydraulic capacity in the Selma collection system has apparently resulted from upgrading several existing wastewater pump stations. Consequently, peak wet weather flows into the County receiving facility have increased in magnitude. K m x During and after any significant rain event (>l= 1.5" of rainfall in 24 hours), the incoming 18-inch gravity sewer line is surcharged. Flow calculations show that under maximum surcharged conditions, this sewer line carves approximately 3,000 gpm into this facility. This surcharge condition can last for 24 hours after a major rain event. With 3,000 gpm entering the facility for 24 hours and approximately 1,700 gpm of pumping capacity, at least 1.9 mg of storage capacity is required on site. The current total storage capacity is 0.6 million gallons. The proposed additional storage will increase the available storage to 2.1 million gallons, which should be sufficient to handle peak flows. An additional magnetic flow meter is required on site to measure the amount of flow diverted to the storage facilities. Currently, only flow leaving the facility is measured. The addition of three manually operated water cannons will facilitate wash down and thorough cleaning of the two existing basins as well as the proposed new tank. Potable water will be used for basin/tank cleaning. Adding more storage at the Selma Equalization and Pumping Facility will give the County the ability to manage peak flows from the Town of Selma collection system safely and effectively and without overflows. 101 m M 101 1 D. Cost Effectiveness The proposed improvements are estimated to cost approximately $695,000. Alternatives to the cylindrical prestressed concrete storage tank include: a cast in place square or cylindrical concrete tank, a cylindrical steel tank, a lined earth basin, or providing higher forward flow pumping capacity. Cast in place concrete structures are more expensive than the cylindrical prestressed concrete structure, A steel tank has less first cost, but much higher life cycle cost due to painting on 5 to 8 year intervals. A lined earth basin is comparable in cost to a prestressed concrete tank, but would require purchase of additional land. Increasing effluent pumping capacity to 3,000 gpm would require new, larger pumps, a 4,0001..f. parallel 16" force main, and a 2,000 l.f. parallel 24" segment of downstream interceptor, thus rendering this option prohibitively costly. Therefore, the most cost effective alternative is construction and operation of a 1.5 million gallon prestressed concrete tank D. User Fee Analysis The cost of this project is minimal compared to the original amount of the SRF Loan. This increase spread over the duration of the loan will not cause a significant increase in user fees (less than $0.02/1000 gallon). E. Environmental Corridor The proposed work will be contained entirely within the existing Selma Pumping & Equalization Station site. The site is already cleared and maintained by the County. A m m X x 50-foot buffer on an existing stream will be maintained. An environmental assessment of the site was prepared for a Clean Water Bond Grant in 1999-2000. This project will not increase the overall capacity of the facility, and therefore will not facilitate, or encourage growth in the tributary service area. There are no secondary or cumulative impacts due to growth associated with this project. 9 Lel m Me _J m r Feb-03 TABLE 4-15 Selma Equalization and Pumping Facilities improvements Estimate of Cost n 0 x EXHIBIT 4-14 JOHNSTON COUNTY COLLECTION SYSTEM SANITARY SEWER OVERFLOWS — JULY 01, 1999 TO DECEMBER 31, 2002 Date Location Spill Volume 08/23/99 Buffalo Creek P.S. 15,000 gallons 09/16/99 Selma P.S. 50,000 gallons 09/28/99 Selma P.S. 5,000 gallons 10/18/99 Selma P.S. 7,500 gallons 04/18/00 Buffalo Creek P.S. 750 gallons 07/26/00 Buffalo Creek Interceptor <1,000 gallons 08/01/00 Buffalo Creek Interceptor <1,000 gallons 12/18/00 Selma P.S. 5,000 gallons 05/05/01 Buffalo Creek F.M. < 50 gallons 06/02/01 Selma P.S. 125,000 gallons 10/02/02 Selma P.S. 10,000 gallons 12/24/02 Selma P.S. < 1,000 gallons JOHNSTON COUNTY SMITHFIELD-SELMA 201 WASTEWATER FACILITIES PLAN AMENDMENT NO.3 - ENGINEERING AMENDMENT NO.3 BUFFALO CREEK PARALLEL FORCE MAIN FEBRUARY 2003 A. Summary, Conclusions Recommendations An additional force main is needed to convey flows from the Buffalo Creek Pump Station to the Neuse River Interceptor. The addition of the force main at this time will increase the capacity of the Buffalo Creek Pump Station, which receives flow from the Selma Pump Station and Equalization Facility. Augmented capacity is required to prevent sanitary sewer overflows (SSO's) during significant wet weather events. B. Project Description The proposed project changes involve the Phase 2 Force Mains as described in Section 4.11 of the 201 Facilities Plan Amendment. The proposed change will involve the construction of a 12-inch line that would parallel the existing 6-inch and 10-inch force mains from the Buffalo Creek Pump Station to the Neuse River Interceptor as part of the SRF loan funding of first phase construction under this 201 Plan Amendment, as opposed to constructing this line in a future phase. The proposed change is shown on a revised Figure 5-2 and Figure G-1 from the 201 Amendment. Revised costs for the proposed project changes are included in revised Tables 4-10 and 4- 13 that are attached. The revised costs include the effects of the proposed project changes, as well as the updated costs based on a detailed cost estimate prepared during engineering design. The cost for the Neuse River Parallel Force Mains, including the 12-inch line, will increase 33 percent from the January 2002 estimate, not including engineering costs and the two percent closing fee for SRF funding. The cost for the original project increased 16 percent. The increased cost for the original force main is Al Eo Engineering Amendment February 2003 Page 2 + primarily due to design modifications because of issues that arose during easement acquisition and adjustment to the cost of the river crossing. C. Justification The additional parallel force main is needed at this time because of the need for additional capacity in the Buffalo Creek Pump Station to prevent surcharging of the tributary gravity interceptor and SSO's during significant wet weather events. The gravity line occasionally surcharges during peak flows and frequently charges during wet weather. SSO's have occurred on several occasions. This segment is the missing piece in the rehabilitation of the Buffalo Creek Interceptor to the new proposed 16-inch parallel force main and 24-inch Neuse River Parallel Force Main. Calculations for the Buffalo Creek pump station are attached as Exhibit 1. D. Cost Effectiveness The alternatives evaluated in the 201 Amendment for the Neuse River Interceptor Paralleling are not affected by the addition of the costs for the 12-inch parallel force main. This force main was identified as a future need in the 201 Plan Amendment No. 3. E. User Fee Analysis The proposed user fees will not change as a result of the proposed changes to the Amendment. The modest capital cost of this project element, together with the low interest SRF loan will not require an appreciable increase in user fees. F. Environmental Corridor The proposed work is within an existing sanitary sewer easement. The total pipeline length for the Neuse River Parallel Force Mains would increase by 1,620 feet. The proposed route is already cleared and maintained as a condition of the county's sewer collection permit. A revised description of the physical environmental for the proposed parallel Neuse River Force Mains is included in the attached revised Table 7-4. w m A R� a ausm�s J _o o9 LL R C I 2 a F= lien T • 7 � ffo IWWW-1 1 r r_ 0 N ✓�i D a a a c c D o CL a u v u a c LL Li "i LL N N E > pNp o CV a' 0 i° a a a u� d � LLI • 1 ' ILL w J rh� 1#1 XF x r x � m m n LL W I ma I N E v I I h i I c H N I 1 C Itl � 7 L 1 I u U. v I 1 (ALL- o o LL r to — 1 C C yp a N C L to a w I 1 X W .x W LL cm jy �.

Summary, Conclusions Recommendations The original 8-inch reclaimed water main along Black Creek Road was designed to supply reclaimed water to a 35-acre farm. In order to allow the reclaimed water main to serve the farm and the newly acquired County property adjacent to the existing County landfill, an alternate alignment has been proposed. The proposed alignment is entirely on County property. The main will increase in size from 8-inch to 12-inch, and the length will increase from approximately 2,930 LF to approximately 6,500 LF. The total project cost will increase by approximately $50,000. The revised alignment will facilitate irrigation on approximately 160 acres of County property, irrigation of turf and ornamental vegetation on a proposed county -state -federal agricultural service complex, which is under design, as well as irrigation of the farm. No adverse environmental impacts will result from the alternate alignment. Construction of the 12-inch main in the alternate alignment is recommended. B. Project Description The proposed changes are to Phase 1 of the wastewater reuse program as described in Section 5.5 of the 201 wastewater Facilities PIan Amendment No. 3. The changes consist of relocation of the reclaimed water main to serve a 35-acre farm from a route along Black Creek Road to a route within County -owned property. The main will be upsized U Al Engineering Amenw, lent February 2003 Page 2 from 8-inch to 12-inch. The proposed changed route is shown on revised Figure 5-5 from the 201 Amendment. The costs for the proposed force maim alignment are included in Table 5-5a, which is attached. The total cost for the upsizing and relocation of the Black Creek main will increase the cost of the project by 60 percent. C. Justification The proposed pipeline realignment is needed to move the pipeline onto County -owned property instead of public right-of-way. By relocating and upsizing the line, the projected wetted acres for Phase I of the Reuse program could potentially increase by 160 acres. Approximately 140 acres will be coastal Bermuda, cropland, and mixed forest, and approximately 20 acres will consist of turf and ornamental vegetation on a planned local -state -federal agricultural services complex. A soils evaluation has been performed for the County -owned property by GreenVest, Inc. The report recommends an annual application of 75 inches on 140 acres, which totals 285 MG. This will reduce the amount of nitrogen discharged to the Neuse River. The line will also serve the farm property as originally designed. A letter of intent from the property owner is attached as Exhibit A. D. Cost Effectiveness The alternatives evaluated in the 201 Amendment for the water reuse program are not affected by the addition of the costs for the new alignment of the reclaimed water main. E. User Fee Analysis The proposed user fees will not change as a result of the proposed changes to the Amendment. The additional costs will be offset by under runs in the reclaimed water project contracts. Op 00 C x Engineering Amenwaent February 2003 Page 3 F. Environmental Corridor The proposed work is within the original environmental corridor between Black Creek Road and County Home Road. The proposed changed route is shown on revised Figure 7-3 from the 201 Amendment. The total pipeline length would change form 2,930 LF to 6,500 LF. The area to be cleared along the proposed route would be approximately 2.06 acres. There are approximately 130 LF of jurisdictional wetlands within the alignment that will be crossed with a directional bore to minimize disturbance. A revised description of the physical environment along the proposed 12" reclaimed water main is included on the attached revised Table 7-2. The alternate route is entirely on County owned property and is outside riparian buffers and wetlands. No threatened or endangered plant or animal species will be affected. No archeological or historical resources will be affected. 2-4 00 00 O m m kl/ N u5� -J JS 1� 0U5"�esy oar y C O0 C o cs 'a `o 0 o� 1 � 5 40.A • s OR +� I r'FAM; '•`�: , fiqw �- c w �a Y 'r � c o o z a R ;0- a � U �' U 0 a �9� oCJ� dS vy � U U in 00 00 x w r Table 5-5a C Johnston County, North Carolina Water Reuse Land Application 12-inch Declaimed Water Main on County Property Description Unit Quantily Unit Cost Total 12-in PVC LF 4500 $ 14 $ 63,000 10-in PVC LF 1200 $ 12 $ 14,400 8-in PVC LF 800 $ 9 $ 7,200 Clearing AC 2 $ 4,000 $ 8,000 Fittings LBS 2000 $ 3 $ 5,000 10" Gate Valve with Box EA 2 $ 1,200 $ 2,400 8" Gate Valve with Box EA 2 $ 1,000 $ 2,000 6" Gate Valve with Box EA 5 $ 700 $ 3,500 20" x 12" tapping sleeve and valve EA 1 $ 5,000 $ 5,000 Erosion Control LS 1 $ 2,000 $ 2,000 Hydrants EA 1 $ 2,000 $ 2,000 Subtotal $ 115,000 Contingencies @ 10% $ 12,000 Subtotal $ 127,000 Engineering and Design $ 6,000 Resident Inspection and Engineering Services $ 6,000 Subtotal $ 139,000 2% SRF Closing Cost $ 2,780 Total $ 142,000 00 00 m w ALTERNATE RECLAIMED WATER MAIN LETTER OF INTENT FROM PROPERTY OWNER 00 00 Al r- �- (- r, February 3, 2003 Tim Broome Director of Infrastructure and Engineering Johnston County Dept. of Public Utilities P.O. Box 2263 Smithfield, NC 27577 Dear Mr. Broome: I am very interested in obtaining recycled water for irrigation on Tract 8376 ( NC Pin No. 1673 59 6343), my home tract. I have more than 35 acres of cleared land on this tract. I am interested in irrigating as much of this tract as possible immediately. I also farm more than 400 acres on other tracts along Galilee Road, Black Creek Road, Long Branch Road, and NC 210 in the vicinity of existing lines where I would like to use this water. I farm even more tracts in other parts of the county if this water becomes available in the future. Based on the soil types and my experience irrigating this land, I can use at least four inches of water per acre during the growing season in wet years. In dry years like this past year I could probably use three times that amount. I am familiar with the restrictions for recycled water use. I have worked closely with Kenneth York, Johnston County's Reclaimed Water Specialist, in the past, and I will work closely with him in the future to assure that all requirements are met. I would love to have this water available by the summer of 2003 if possible. I would appreciate any assistance you could give. Sincer , �— L" mes W.

Wilson, Environmental Engineer NPDES Unit Subject: Johnston County Smithfield - Selma EA (Central Johnston County WWTF 201 Plan) Rehab/ Expansion Issues NPDES No. NCO030716 Johnston County - 1 1,R R �C,L.EI�I p I have reviewed portions of the 201 Wastewater Facilities Plan submitted by Hazen and Sawyer on behalf of Central Johnston County. The proposed project includes expansion of the Central Johnston County Wastewater Treatment Facility (WWTF) to meet future growth needs and provide biological nutrient removal, expansion and rehabilitation of the collection system, and reuse of a portion of the wastewater for irrigation. Due to the Division's time delay with the revised nitrogen allocation for dischargers in the Neuse River Basin and EPA's approval of the total maximum daily load (TMDL), there may have been some confusion with regard to permitted flows at the county. The Division originally drafted and noticed the renewal for Central Johnston County on June 2, 1998. The draft permit included phased limits for 4.5 MGD and 4.99 MGD, with the provision that an Authorization to Construct (ATC) permit be issued prior to expansion to the 4.99 MGD flow. No final permit was issued following this draft due to the previously stated reasons. Central Johnston County received an Authorization to Construct permit March 20, 1997 for plant modifications for the addition of an oxic and anoxic zone to assist with nutrient removal. This ATC never approved an expansion in flow to 4.99 MGD. The 201 Wastewater Facility Plan indicates that Central Johnston County WWTF is in the process of increasing the capacity of the plant to 4.99 MGD. This is also reflected in Table 2-2 of the plan [p. 2 41. The plan should reflect that the permitted flow is currently at 4.5 MGD. The Division has not yet finalized a permit for 4.99 MGD and the county is not authorized to discharge flow in exceedance of 4.5 MGD monthly average flow. The 201 plan correctly states that the Division has received a request for speculative permit limits at a flow of 6.5 MGD. The Division has completed a preliminary review of limits for a flow of 6.5 MGD and offers those with this document (an official letter to the County will be offered in follow-up to this documentation). Because the projected flow for the county is 7.0 MGD, the county should clarify at what flow speculative limits are requested. 0 0 The NPDES Unit supports the proposed wastewater reuse project, as a long-term effect may be the reduction in effluent discharge as the County's population continues to grow. The County should be aware that tertiary quality effluent is required for reuse water [ref. 15A NCAC 2H .0219(k)l. In addition to treated wastewater reuse, other alternatives to discharge must be documented prior to the issuance of a permit (for example, spray irrigation of remaining wastewater - not specifically for reuse). The county should refer to the NPDES Unit's Engineering Alternatives Analysis Guidance document that is available on the Division's website: [http://h2o.enr.state.nc.us/NPDES/documents.htmll. Based on the Division's revised allocation of total nitrogen load, Central Johnston County was allocated a total load of 56,200 lbs/year at the flow of 4.99 MGD. The Neuse Nutrient Management Strategy rule establishes additional requirements for facilities planning to expand beyond their 1995 permitted flows. An expanding facility must acquire any nitrogen allocation it needs for the added discharge before it can apply for the necessary NPDES permit modification. The facility can (1) provide additional treatment in order to meet its original allocation, (2) acquire additional allocation from existing point sources, or (3) acquire additional allocation from nonpoint sources through the Wetlands Restoration Fund. In the last case, the facility must obtain 30 years' allocation prior to permit application. In any event, the facility's total allocation cannot be greater than the annual mass limit equivalent to 3.5 mg/L TN at the expanded flow. Facilities joining a group compliance association are not subject to individual limits but will be responsible as a group for meeting their collective allocation. Central Johnston County has expressed its intent to join such an association, so much of this explanation does not apply directly to its discharge requirements. However, the discussion is still relevant to the County's nitrogen allocation and the Iimit the association must meet. Note that the Division expects to complete a more comprehensive modeling effort in early 2001 and will use those results to better define the nitrogen reduction target for the Neuse River estuary. It is not clear from preliminary results whether the target will need to be changed. Be aware that if the target level is lowered, it could lead to further reductions in the point source allocations. To reiterate. design considerations must include the ability to achieve an annual TN load based on a concentration of 3.5 mg/1 at 6.5 (or 7) MGD, regardless of the County's chosen route of compliance. /Please refer to I5A NCAC 2B .0234J cc: Central Files NPDES Files RRO/ Water Quality Section x SPECULATIVE LIBUTS CENTRAL JOHNSTON COUNTY WWTF Parameter Summer Winter Flow (MGD) 6.5 6.5 BOD5 ( /1) 5 10 NH3-N (mg/1) 1 2 DO ( /l) daily avg. 6 minimum 6 minimum Fecal cola orm (#/ 100ml) 200 200 TSS 30 130 TN 56,200 lbs/year (annual compliance load effective January 2003) TP 1 mg/1 (monthly average) - or - 2 mg/1 (per defined quarter if an association member) Monthly averages are presented above unless stated otherwise.
