This facility discharges into Dutchman'sCree classified C waters in the Yadkin -Pee Dee River Basin. The receiving stream is not listed on the 2003-303(d) list; nor are there any special considerations for it in the river basin plan. The town is a member of the Yadkin -Pee Dee River Basin Association (as such, their instream monitoring will continue to be waived). The town has a modified pretreatment program. During the speculative limit development for this facility, it was determined that the . stream flow data previously being used was incorrect. USGS confirmed that the 7Q10 value at this location should be 2.54 cfs, not 15 cfs as had been used in prior permits. A level B model run using this new stream flow information showed that a 0.981 MGD discharge is allowed in this receiving stream, under very stringent limits, however it is unlikely that the assimilative capacity could accommodate any additional future flows from this facility. The facility was informed that there would be a significant change in permit limits at the proposed flow and they decided to move forward with the expansion request. According to the EAA and discussions with the regional office, much of the flow justification for this expansion is based on the need to relieve high flows at the town's Bear Creek facility. It was indicated that the town might apply for an expansion at that facility as well. Changes Incorporated into Permit ➢ A limits page was added for a permitted flow of 0.981 MGD.

They decided that any expansion would come at the Dutchman Creek Plant. Thats when they decided to move some flow from Bear Creek to allow some capacity there and as the Dutchman Cr facility had some capacity that gave them an immediate solution for Bear Creek. At the same time they were initiating the process for expansion at the Dutchman Creek Facility.

We asked the town to provide us with documentation for their increase request. Over half of the justification they provided had to do with flows from the Ingersoll Rand and Walmart projects. So we were surprised to see that collection system permits had already been issued for those flows under the facility's current capacity. I've spoken with Tom and Susan and we're all at a loss. As is stands, the information the town has submitted really does not explain why they need this additional flow. But in the end, there's only so much we can go back and forth on this, so if you feel that the flow request is justified then we'll move forward.

Anyways, I did a quick look through the Mocksville EAA and thought that overall it looked good. They provided flow justification, costed out alternatives, obtained land costs, etc, etc. My one question would be on the flow justification. They are requesting a 0.3 MGD increase to account for the following connection (an existing Ingersoll-Rand plant at 101,000 gpd; anew Walmart at 65,140 gpd; Crestwood Development 125,000 gpd; and Davie School 5700 gpd). Fast track WQ permits were already issued by WSRO for pump station/force main to connect Ingerdol-Rand and Walmart to the Dutchmans Creek plant. Susan- does this make sense? By issuing these WQ permits does the Region assume that existing plant capacity can handle this flow, or do they issue these WQ permits and assume that NPDES will ultimately approve the requested flow increase down the road. Seems like this permitting could defeat the intent of the EAA review process, if the region has already approved the connection before we address the proposed expansion within the EAA. I'm not sure about the Crestwood flow request for 125,000 gpd- their letter states they are requesting an increase from 75,000 gpd to 100,000 gpd (so does this mean that they just need 25,000 gpd?) to serve the current expansion underway, and will require additional flow by April 2005. Overall, I'm not sure what is already piped to the WWTP, and what will go there in the future. As stated, I think the EAA is well -documented, but the flow request and WQ permitting issue should be looked into before proceeding. Toya- I didn't consider the Bear Creek WWTP alternative, since it seems the Region has already permitted the connection to Dutchman's Creek. If we ultimately agree with the EAA, then the next step is to prepare the draft permit mod for Public Notice and run a WQ model if there are no specs for this proposed expansion. But I'm not sure if you were assigned all of this.

Grey, Jr., Project Engineer Grey Engineering, Inc. P.O. Box 9, 151 Industrial Boulevard Mocksville, North Carolina 27028 JAN 2 5 2005 -- C_ R -"'ILA QpALITY POviT Sc:L,cr P,esuru Dear Mr. Grey: In response to your request for low -flow data, the U.S. Geological Survey (USGS) does not have site -specific, low -flow discharge data for Dutchman Creek near Mocksville, NC (station id 0211701350, drainage area 108 mi2). The updated low -flow characteristics that are provided on the attached sheet have been computed by cor- relating the runoff characteristics of a nearby USGS surface -water site upstream of the request site. Please note that the flow estimates do not specifically account for the presence of any diversions or regulation, present or future, which may occur upstream of the request site. The upstream surface -water site used as the index site is Dutchman Creek near Comatzer (station id 02117000, drainage 83.8 mi2). Available records of discharge at this site include continuous records of daily mean discharge from March 1940 through January 1942 and partial records consisting of 10 miscellaneous measurements obtained during the 1956, 1963, 1970-71, 1973, 1975, and 1979 water years. Assessment of low -flow character- istics estimated for this site in October 1987 (7Q10 discharge of 15 ft3/s) were based on an analysis that used 7 of the 10 miscellaneous measurements at the index site. No previous analyses have been completed using the continuous records of discharge at the index site. A re-evaluation of the low -flow characteristics has been completed for the index site (Sta.02117000) using avail- able continuous and partial records, and estimated low -flow discharges are lower than the previous estimates. However, the updated estimates are more consistent with low -flow characteristics (in terms of yields or flow per square mile of drainage area) at two other upstream USGS sites on Dutchman Creek (Sta. 02116770, drainage 57.6 mil) and Cedar Creek (Sta. 02116790, drainage 19.6 mi2). Updated low -flow analyses were also completed at these two additional sites to help clarify the low -flow characteristics in the Dutchmans Creek basin. Available geographic information system coverages of soil maps here in the NC District office indicate that poorly drained soils occur across much of north and northeastern Davie County. The effect of poorly drained soils within a basin suggests that water infiltration rates into the soils would be low (relatively to well -drained soils), resulting in less storage of water within aquifer that would be used to sustain base flows during extended dry periods. This information is considered preliminary and subject to revision pending further analysis as further data were to become available, and is made available through our cooperative program of water -resources investigations with the North Carolina Department of Environment and Natural Resources.

This report will address only the Dutchmans Creek facility. The facility is located in Davie County on Garwood Road. See Figure 1 for a vicinity map, Figure 2 for a topographic map. There is no resident staff located at the facility. The address for the Town of Mocksville Public Works Department is 337 Sanford Avenue, Mocksville, NC 27028. Their phone number is (336) 751-2519. This report was prepared by Carl Davidson, El and John Grey, PE of Grey Engineering M14 Inc., a consulting firm contracted by the Town of Mocksville. Grey Engineering is located at 254 Water Street in Mocksville, NC 27028 (336 751-2110). This report supports a request to increase the permitted flow from the Dutchmans Creek WWTP from 0.68 mgd to 0.98 mgd to accommodate additional industrial, commercial and institutional waste flows. The additional flows are provided by the Ingersoll-Rand Corporation (101,000 gpd), the Wal-Mart complex (65,140 gpd), Crestwood Farms International (125,000 gpd) and the William R. Davie School (5,700 gpd). See Appendix A for additional flow documentation. There are two phases to this project. The first phase has been permitted and consists of a duplex pump station and approximately 6275 feet of 6" force main to deliver the Ingersoll-Rand wastewater to the Dutchmans Creek WWTP. The second phase of this project is an expansion of the Dutchmans Creek WWTP by the addition of influent screening, aeration basin, clarifier, aerobic digester, chlorination and dechlorination to increase the rated treatment capacity by 300,000 to 0.98 mgd. �, Existing System The Dutchmans Creek WWTP is an extended aeration facility initially constructed in f, 1970 and expanded in 1983. The treatment facility is in good condition and performs well. The average daily flow for 2004 was 515,000 gpd or 76% of the plant's rated capacity. The plant serves a residential population of approximately 3500 persons. 01, Current average annual daily wastewater flows (gpd) from various sources are as follows: ran Residential 210,000 Commercial 60,000 Industrial 150,000 Institutional 15,000 1&1 80.000 515,000 The plant is served by approximately 45 miles of sewer line (423 in*miles). I&I is non excessive by CWSRF standards, however, the Town has an active sewer rehabilitation program and is working to eliminate I&I from the system. 2111105 Engineering Alternatives Analysis Page I of 6 Dutchmans Creek WWTP (NC0021491) F, I -( yes EVALUATION OF DISPOSAL ALTERNTIVES The options available to the Town of Mocksville to provide an additional 300,000 gpd of additional wastewater treatment capacity are: 1) Transfer the additional wastewater to the Cooleemee WWTP 2) Connect to a privately owned treatment works. 3) Install a conventional subsurface treatment system. 4) Install a Drip irrigation system 5) Install a spray irrigation system 6) Reuse the water after treatment 7) Surface discharge through the NPDES program 8) A combination of two or more of the above options. 1. Connection to a Different Publicly Owned Treatment Work (POTW) r The nearest feasible POTW in Davie County is the Cooleemee WWTP owned by the County of Davie. The Cooleemee WWTP (NC0024872) is permitted to discharge 1.5 7 mgd. The average discharge in 2004 was 0.472 mgd. A force main of approximately 46,000 feet would be needed in order to pump the waste from the Dutchmans Creek WWTP to the Cooleemee WWTP. See Figure 6 for the geographical relationship 1 between The Dutchmans Creek Plant, the Cooleemee Facility, and other elements discussed. �► Flow Chart #1 in Appendix F shows a process flow description for this alternative. Table #1 in Appendix F summarizes the costs. ! The estimated capital cost of this option is $2,816,000. The increases in annual operating costs are projected to be $129,000 to cover the utilities, mechanical maintenance and treatment charges from the Cooleemee WWTP. 2. Connect to Private Treatment Works There are no privately owned treatment plants in Davie County. 3. Individual / Community Conventional Subsurface Systems A subsurface system for the disposal of 300,000 gpd of waste would require secondary treatment prior to disposal. This would be accomplished through the expansion of the Dutchmans Creek plant, which would include an aeration basin, clarifier, aerobic digester, chlorination, and dechlorination. The soils in the area of the WWTP are ^ discussed in Appendix D and support a loading of 0.2 to 0.25 gpdpsf. Using an application rate of 0.25 gallons per day per square foot would yield a drain field of approximately 1,200,000 square feet. Given the 9 foot minimum center to center 4 2111105 Engineering Alternatives Analysis Page 2 of 6 Dutchmans Creek WWTP (NC0021491) 7 distance of parallel tile lines, and the stipulation that no one tile line should be longer than 150 feet, this would require approximately 400,000 linear feet of drain line and �► would cover an area approximately 83 acres in size. An area of the same size would be required to serve as repair fields. The Town of firl Mocksville's Dutchmans Creek WWTP is located on an 8 and '/ acre parcel of land, so additional land would have to be purchased Mn Flow Chart #2 in Appendix F shows a process flow description for this alternative. Table #2 in Appendix F summarizes the costs. Va' The estimated capital cost of this option is $6,495,800. The increases in annual operating costs are projected to be $24,000 to cover the increased costs of utilities, sludge disposal, mechanical maintenance and labor associated with the mowing of the drain field. M 4. Drip Irrigation In order to utilize drip irrigation the wastewater must first be treated. This would be accomplished through the expansion of the Dutchmans Creek plant, which would include an aeration basin, clarifier, aerobic digester, chlorination, and dechlorination. Then, the drip system must be installed. An application rate of 0.2 gallons per day per square foot has been assumed. This yields an effective area of 34 acres. Assuming a 25% buffer, this disposal method would require approximately 45 acres. A 9,000,000 gallon storage pond (30 days) would be required, as well as the necessary pumps, piping, and drip system. OM Flow Chart #3 in Appendix F shows a process flow description for this alternative. Table #3 in Appendix F summarizes the costs. on The estimated capital cost of this option is $3,000,500. The increases in annual operating costs are projected to be $29,000 to cover the Mn increased costs of utilities, sludge disposal, mechanical maintenance, and labor associated with the mowing of the drip field. CM 5. Spray Irrigation In order to utilize spray irrigation, the wastewater must first be treated. This would be �., accomplished through the expansion of the Dutchmans Creek plant, which would include an aeration basin, clarifier, aerobic digester, chlorination, and dechlorination. Then, the spray system must be installed. An application rate of 0.2 gallons per day per square foot has been assumed. This yields an effective area of 34 acres. Assuming a 25% buffer, this disposal method would require approximately 45 acres. A 9,000,000 gallon storage pond (30 days) would be required, as well as the necessary pumps, piping, and spray system. 2111105 Engineering Alternatives Analysis Page 3 of 6 fm Dutchmans Creek WWTP (NC0021491) Flow Chart #4 in Appendix F shows a process flow description for this alternative. Table #4 in Appendix F summarizes the costs. The estimated capital cost of this option is $2,580,500. The increases in annual operating costs are projected to be $29,000 to cover the increased costs of utilities, sludge disposal, mechanical maintenance and labor associated with the mowing of the spray field. 6. Reuse There are two categories of end users that are capable of accepting and using treated wastewater, agricultural and industrial. 6.1 Golf Course Irrigation There are no local agricultural systems that utilize separate irrigation systems to irrigate crops. There are, however, two golf courses in the vicinity that have irrigation systems that draw from ponds located on the courses. One is the Hickory Hill Golf Club, located approximately 3 miles away. The other is Twin Cedars Golf Course, located approximately 5 Y2 miles away. The Hickory Hill Golf Club is located on Lake Louise, a part of Ellsworth Creek (stream index 12-102-16.5-(1)), which is classified as `B'. Twin Cedars Golf Course is bisected by Peeler Creek (stream index 12-103-1-(1)), which is classified as 'C'. In the case of either of these destinations, the water must first be treated by an expansion of the Dutchmans Creek WWTP, stored on -site and transferred to the point of use. A pumping station would be required with associated force main to transport the reclaimed water to its final destination. In the case of irrigating either golf course with the effluent, a separate pump station with associated force main would have to be installed. The Hickory Hill Golf Course is nearer and the pump station would need a capacity of approximately 208 gpm and 15,800 feet of 6" force main. Flow Chart #5 in Appendix F shows a process flow description for this alternative. Table #5 in Appendix F summarizes the costs. The estimated capital cost of this option is $2,960,600. The increases in annual operating costs are projected to be $27,000 to cover the increased costs of utilities, sludge disposal, mechanical maintenance and labor. �—► 6.2 Industrial Reuse There is only one industrial installation in Davie County that could utilize the wastewater, that being the Jockey International dying plant located in Cooleemee, NC. To reuse the wastewater in an industrial dying plant, the effluent must be polished 1'! 2111105 Engineering Alternatives Analysis Page 4 of 6 Dutchmans Creek WWTP (7VC0021491) Ow �a further through membrane treatment. The polishing cell has an estimated cost of $ 2 / gallon for a total of $ 600,000. In the case of Jockey International, a pump station and force main would be required to transport the waste to the plant. This system would include a pump station with a capacity of approximately 210 gpm and 45,000 feet of 6" force main. For reuse at the Jockey International dying plant, a tank, pumping station, Ref and internal piping system would be required in the facility itself. Jockey International currently has a pretreatment permit to treat and discharge up to 475,000 gpd into the Davie County wastewater system. This waste flows to the Cooleemee WWTP IM (NC0024872). Flow Chart #6 in Appendix F shows a process flow description for this alternative. F" Table #6 in Appendix F summarizes the costs. The estimated capital cost of this option is $3,887,000. The decrease in annual operating costs are projected to be $71,000. These include increases to cover utilities, sludge disposal, mechanical maintenance, and labor. These increases are more than offset by the projected income from the purchase of the reclaimed water by the Jockey Corporation. It must be noted that this purchase is only listed here as a possibility. Jockey Corporation has not been approached about purchasing reclaimed water and no negotiations have taken place. In a rural location such as Davie County, reusing the wastewater is cost prohibitive. Reuse lends itself more to highly industrialized settings where the treatment facility and end user are in close proximity. M' 7. Surface Water Discharge Through NPDES Program The Dutchmans Creek WWTP currently discharges its effluent into the surface waters of Dutchmans Creek under NPDES permit # NC0021491. The additional facilities include an aeration basin, a clarifier, an aerobic digester, chlorination, and dechlorination. A site plan is attached as Figure 3. The Town of Mocksville owns the 8.25-acre parcel the treatment plant is on. Due to the layout of the existing plant, and the location of the flood plain, the Town of Mocksville must purchase a 50' wide strip of land to accommodate the expansion. Flow Chart #7 in Appendix F shows a process flow description for this alternative. aq Table #7 in Appendix F summarizes the costs. The estimated capital cost of this option is $1,687,000. fm The increases in annual operating costs are projected to be $18,000 to cover the increased costs of utilities, sludge disposal, mechanical maintenance, and labor 1=4 associated with the increased amount of equipment. 0" 2111105 Engineering Alternatives Analysis Page S of 6 Mq Dutchman Creek WWTP (7VC0021491) 8. Any Possible Combination of the Above Options No other combinations of the above referenced alternatives appear feasible. 9. Economic Evaluation Summary The table below indicates the total costs associated with each of the alternatives analyzed. See the detailed analysis in Appendix C for further information. Costs Transfer 300,000 gpd to Conventional Subsurface Drip Spray Reuse to Golf Reuse to Expand Capacity and Revise Cooleemee System Irrigation Irrigation Course Jockey NPDES Permit WWTP Capital $ 2,816,000 $ 6,495,800 $3,000,500 $ 2,580,500 $ 2,960,600 $3,887,000 $ 1,687,000 Annual $ 129,000 $ 24,000 $ 29,000 $ 29,000 $ 27,000 $ (71,000) $ 18,000 NPV $ 4,310,752 $ 6,773,893 $3,336,530 $ 2,916,530 $ 3,273,455 1$3,064,307 1 $ 1,895,570 10. Recommendation It appears the most economically feasible alternative is to discharge the treated effluent directly in Dutchmans Creek under a revision to the existing NPDES permit # NC0021491. 2111105 Engineering Alternatives Analysis Page 6 of 6 Dutchmans Creek WWTP (NC0021491) I 0 15000 30000 SCALE: 1'= 15000' STA2„�_oUTC_0� TOWN OF M O C K S V I L L E GREY ENGINEERIN Civil Design and SurveyiG, INc.

This property is located off the north side of US Highway 64, at the end of Garwood Road, in Davie County, North Carolina. The property is identified in the Davie County Tax Office on Tax Map J-6 as Tax Lot 49. The Davie County Tax Office indicates the total land area of this tax lot to be 71.05 acres. This land is improved with a single-family house that contains 1,627 square feet, a barn and other miscellaneous outbuildings. ItYou have requested that 1 estimate the fee simple value of the unimproved land and the value of the life estate for the house and land area allocated to this house. For purposes of this appraisal, I have allocated about one acre to the house and outbuildings, resulting in about it 70.0 acres of unimproved land. The first section of the appraisal describes and values the 70.0 acres of land. The value of this land is estimated using the Sales Comparison Approach. I have obtained sales of six parcels of land to use as a basis for estimating the value of this land. itThese six land sales are selected because they are the most recent sales of land in the area that would have a highest and best use similar to the property being appraised. Based on these sales, I am estimating the value of the 70.0 acres of unimproved land to be about $4,300 per Itacre, for a total value of 5300,000. Is The value of the life estate of the house and land area allocated to this house is obtained by First estimating the fee simple market value of the property. Using sales of other single-family honks, the fee simple market value of the house and one acre of land is estimated to be $83,000. To estimate the value of the life estate the current fee simple value of the house is increased to obtained the estimated value at the time of death of Mr. and Mrs. Garwood. Using tables obtained from TAXFACKS, I am estimating the remaining life expectancy to be five years. Increasing the current fee simple value by three percent compounded annually, the future value at the estimated time of death is $96,200. This future value is then discounted to a 0 1365 Westgate Center Dr., Suite H-2 • Winston-Salem, NC: 27103 Telephone (3 36) 659-1000 • Facsimile (3 36) 659-1111 4 Ms. Christine Sanders .January 22, 2004 Page Two present value to obtain the value of the lile estate. Taking into Consideration Current financing rates and uncertainties In estimating future values and remaining life expectancies, I have "► selected a discount rate of ten percent annually. Discounting the future value of $96,200 to a present value at 10 percent discounted annually, the estimated present value, or value of the life estate of the house and one acre allocated to the house, is $60,000. Adding the estinlatcd fee simple market value of the 70.0 acres of unimproved land of $300,000 to the estimated value of the life estate of the house and land area allocated to the house of $60,000, the combined value of the property is estimated to be S360,000. The estimated value of the property is subject to general assumptions and limiting conditions. These general assumptions are located in the Addenda of this report. This value is also contingent upon the following specific assumptions: • I have estimated that about 20.0 acres of the unimproved land are located in a flood area. If a survey determines that the flood area is substantially different from my estimate, the value of the property should be revised accordingly. • There are an underground fuel storage tank and an Undergl-ound heating oil storage tank located to the rear of the residence. The estimated value of the property assumes that the land is not contaminated fi-orn these tanks. If it is found that the land is contaminated, the estimated value should be revised to reflect the effect that this contamination Could have upon the value of the property. The following narrative appraisal describes the property and the methodology used to estimate the value of the property. I appreciate the opportunity to assist you with this appraisal .

See the attached Figure 3, Topographic Site Map and Figure 4 Soil Survey Map for reference. The area of planned expansion contains soils classified as Gaston Clay Loam. This soil is typically moderately eroded and has mixed subsoil material into the remaining surface ,I, layer, caused by tillage associated with farming. Water and air move through the soil at a moderate rate. The water table is generally greater than 6 feet from the surface. r, Also included in this classification are small areas of Enon and Mecklenburg soils, which are slowly permeable. These soils typically make up from 5 to 15 percent of the classified area. These areas are typically used for cropland or pasture. The site also contains some Chewacla Loam in the flood plain along Leonard and Dutchmans Creeks. These soils are frequently flooded for brief periods of time. Water and air move through these soils at a moderate rate. The seasonal high water table is typically within a depth of 1-'/Z feet. The depth to bedrock is usually more than 5 feet. Pq Also included in this classification are small areas of Altavista, Buncombe, Riverview, and Roanoke soils. Typically the Altavista soils are found on flood plains and Buncombe soils are found adjacent to stream channels. The Riverview soils are typically found in slightly higher positions, closer to stream channels. The Roanoke soils are typically found at the base of upland slopes. '&' The local Environmental Health office typically allows loading rates in the range of 0.2 to 0.25 gallons per day per square foot for these types of soils.
