Facility Name: Pisgah Downs County: Transylvania Owner: Frank A. Moody. II Post Office Box 2001 Brevard, North Carolina 28712 (828)966-9336 Report By: David D. Smith. P.E. David D. Smith and Company 46 Haywcx}d Street. Suite 201-A Asheville. North Carolina 28801 (828) 254-4448 B. Project Description: The subject project is located on fligh\•:n 280 in Transylvania Count• npproximatcl% 8 mile: ['ruin downtown Brevard and 5 miles Irom Pisgah Forc;t. One hundred thousand (100.000) square I"eet of 0111cetretail space along with adequate parking is proposed to he constructed on the 14 acre site. The site is hounded by NC' Hi­hwav 280 on the west- hv private property oil both the north and south and by Boyleston Creek ul the cast. One building along %k•ith a shed is currently located on the proposed project site. Wastewater Generation: 100.000 I't2 office/retail space is planned. Al the regulation design Ilo\v of 120 gpd per I.000 1't2 of floor space the total daily flow is 12.000 GPD. C. Existing Facilities: An existing drain Field is located on site. This disposal facility. huwever. is adequate to scrN c the existing building only. D . Single Phasc C)n;truciLlon: The project will he built in a single phase. Thus; necessitating the construction of a wastewater treatment facility at the onset of site development. I1. EVALUATION OF DISPOSAL ALTERNATIVES: A. Connection to a Sewer Collection System: No public or private sewer system currently serves the subject property. An existing sewer collection system. owned by Transylvania County. is located 4.9 miles from the site. Because of prohibitive cost to construct a pump station capable of pumping waste vatcr over the mountain which lies between the site and the collection further cvahlatir•rl iti unneces;ary. Telephone: (828) 254-4448 Fax: (828) 255-0140 Mr. Weaver April 28. 2000 Page of 4 r � Planned Sewerage System: At present, Transylvania County does not have firm plans to extend the sewer collection system. However. discussion with the County Manager indicates that extension of, the collection system an additional 1.5 to ? miles within the next live years could he a possibility. B. Land Based Disposal: 1. Subsurface Disposal Systems: Soil scientist. Dr. James E. Shelton has investigated the site and performed soil sampling related to the feasibility of utilizing an on -site subsurface wastewater disposal system for this project. His report (attached) stated that one location (Field #3) on the site would he an acceptable location if' large enough to accommodate the planned building requirements. His assessment of Field #1 indicated the presence of quarried gravel. Thus. suggesting this to be in the area of the existing drain field for the current building. Field #1 cannot be utilized for a suhsurl'ace.disposal system. Durinc Dr. Shcho n s ;:vaiimiicm if Fle] J 91 allLIVIa! soik %';h cr,:ck ra` CI \1ilrC encountered 14 — IS im_hes below the naturally occurring soil surface. These soils were saturated. Thus. indicating that this area is subject to periodic flooding. Field 92 location is same as the proposed location of the paved parkin, area. Conventional Subsurface System: An estimate of the scale of a conventional suhsurl'acc system has been calculated (calculations attached). Given a reasonable estimated LTAR fur �7 the region of 0.4 gal/fr/day. 4.6 acres of land will he required to accommodate a ,,,,~`' conventional drain field and repair area. Based on Dr. Shelton's evaluation and set -hack requirements. the land available for use as a subsurface disposal system is 0.7 acres. Therefore, a conventional septic system cannot he located on the subject site. Modified Subsurface System: Modifications (15A NCAC 18A .1950) to a conventional septic tank system were evaluated with conclusions as follows: Field #1 cannot he considered: modil'ied systems will not work at Field #2 due to the presence of saturated soil at shallow depths and the fact that this is the location of" proposed paved parkin, area: sufficient land is not available in the area of Field #3. Low Pressure Pipe System: Fields #1 and #2 cannot he used for an LPP system for. the same reasons previously stated. Field #3 was evaluated l'or required land area. Given an LTAR ol' 0.4 gal/ft'/day. 11.3 acres of )and will be required to accommodate an LPP system including the repair area. Therefore. an LPP systems cannot he located on the subject site. 2. Surface Disposal Systems: Spray Irrigation: As previously stated, thc.subject site is bordered by Boyleston Creek. NC Fli,,hwav 280 an(I orivalr pr(iperty. The proposed bui!din ,s tee Le 1( sated (r the bite[ ,.,i;] utilized as office/retail space, thus public facilities. Based upon NCDENR set-hack/buffer requirements. none of the site will be available for use. Therefore, a spray irrigation type of wastewater treatment facility is not a possible alternative. Drip Irrigation: After evaluation of the site based upon NCDENR set-hack/buffer requirements, less than one acre of land will be available for wastewater disposal by a drip irrigation method. Under ideal circumstances a minimum of 1.1 acres is required for application of the wastewater with an additional 1.5 acres required for 30 days of wastewater storage. Therefore, a drip irrigation type of wastewater treatment facility is also not a possible alternative. C. Surface Water Discharge: Stream flow tnlormation: The USGS was consulted to obtain stream flow information fur the proposed discharge's receiving stream, Boyleston Creek. Information provided by Mr. Telephone: (828) 254-4448 Fax: (828) 255-0140 Mr. Wcavcr April 28. 2000 Curtis Weaver on nearhy similar streams was used to estimate a 7Q10 flow for Boyleston Creek at the proposed discharge location of 0.45 to 0.51 cl's. Description of' Proposed Facilities: 11 is proposed to construct a 15.000 GPD dual -train extended aeration package -type wastewater treatment plant, including tertiary filters it' required, consisting of the following treatment components: 5.000 gallon flow equalization tank with dual alternating pumps and controls. 15,000 gallons of aeration with diffusers. blowers, motors and controls. liar screens will he provided as part of the aeration tanks and will include comminutors and automatic reversing controls 3.000 gallons of anoxic denitrification with mixing equipment. Dual 1.500 gallon clarifiers. with a total of" 200 Ih of, surface area. .Airlift hiosolids return pumps and airlift skimmer pumps, aerated hiosolids holding tank, .000 -allon capacity with s!perr !ant holding tank integral with the treatment plant. 600 gallons, total, chlorine contact tank to provide the minimum 30 minute retention time with full grating de -chlorination system integral to chlorine contact tank. Standby power will he provided if required. 6" gravity collection sewer system. No third party casement will be required for discharge to Boyleston Creek. Cost: Following is a cost estimate of the proposed discharge system: Wastewater Treatment Plant 15.000 GPD WVVTP S91,800 Tertiary Filter 40,000 Site Work 10J)(K) Collection System 25.000 Construction Contin(cncy 17.000 Engineering _ '� (000 TOTAL $ 203,800 Annual Operating Expenses Operator $3.500 Monitorim, 2 S00 1 lec•tnctty 3,500 Slud"c Management 2.000 Fees 500 Maintenance 2.000 TOTAL $ 14,000 Telephone: (828) 254-4448 Fax: (828) 255-0140 Mr. Weaver April 28, 2000 Page 4 of 4 III.
