Tucker, Cilimherg REVIEWED BY: BACKGROUND: The Virginia Department of Transportation(VDOT)desires to replace currently operating zero discharge mineral oil sewage waste systems at its two Albemarle County rest areas on 1-64 with connections to the Crozet Interceptor and, furthermore, to replace the existing on-site well with a connection to public water at the I-64 West Rest Area. (The request is fully described and justified in Attachment A.) The Rivanna Solid Waste Authority(RSWA),in anticipation of the possible need to dispose of leachate from the Ivy landfill, desires the ability to connect to the Crozet Interceptor along the same corridor as used for the I-64 West Rest Area connection. (The request is fully described and justified in Attachment B.) All connections will be via private service lines not available to other properties. DISCITSSION: The Water Resources Manager and Albemarle County Service Authority have both provided comment. (See Attachments C and D) VDOT's consultant notes numerous problems with the mineral oil sewage waste system, attempts to remedy some of the problems and system demands that have made the system malodorous at its current and anticipated levels of usage. While several alternatives to this system are possible,the Water Resources Manager supports connection to public sewer as much preferable to package treatment, pump and haul or spray irrigation. Another type of non-discharge waste recycling system is a possibility, but has not been explored by the applicant as of this writing. Non-discharge systems do require some level of pump and haul. RSWA currently has leachate waste hauled and considers connection to the Crozet Interceptor to be a desirable future alternative. Again, other alternatives exist,but are either not desirable (point source discharge Ind treatment and pump and haul) or limited in their utility (in-situ treatment of groundwater through bio- remediation). As to water at the I-64 West Rest Stop, the VDOT consultant cites reported inadequate capacity to meet future demands. A draw-down test for this well is expected to verify flow,but results have not been made available as of this writing. Additional wells have not been drilled to determine if adequate groundwater exists elsewhere on the site. The aforementioned requests are all for properties located in the Rural Areas as designated by the Comprehensive Plan. Regarding provision of public utilities, the Comprehensive Plan is intentionally specific in objective and strategies as to where and under what circumstances public utilities should be made available(p. 146): OBJECTIVE: Provide public water and sewer services to the Urban Area and Communities. STRATEGIES: Follow the boundaries of the designated Growth Areas in delineating jurisdictional areas. Only allow changes in jurisdictional areas outside of designated Growth Area boundaries in cases where the property is: (1) adjacent to existing lines: and, (2) public health or safety is endangered. Further, the Comprehensive Plan warns that "such utilities are not to be extended to the Rural Areas as these services can increase development pressures" (p. 146). In addition, the Crozet Interceptor was constructed and has existed with the intent to serve only growth area properties, particularly the Community of Crozet, without intervening connection to Rural Area properties. AGENDA TITLE: Service Authori_y Jurisdictional Area Request-VDOT Albemarle County Rest Areas and Rivanna Solid Waste Authority Ivy I Andfill AGENDA DATE: November 1, 1995 Page 2 The subject requests in each case lie several miles from existing public utilities. (It is not known if re-location of the rest areas closer to public utilities near the Crozet interchange would be a feasible alternative.) Connection would either be constructed along existing VDOT right of way or cross country. The sewer connections would involve pumping and force mains. Although intended to be via private lines, such connections have the potential of creating additional pressure for connection and setting a precedent for connection in the Rural Area, particularly to the Crozet Interceptor. The requests do not satisfy the adjacent to existing lines requirement. The malodorous condition of the existing rest area waste systems is characterized by the applicant as "unsanitary", although it is of some question that public health and safety is endangered. The landfill leachate can pose a public health concern if not properly disposed of. In both cases it should be noted that as water supply watershed properties,package treatment and point source discharge is undesirable. (The County Attorney believes that VDOT could install package treatment plants without County approval should the permitting agencies allow.) Regarding water to the I-64 West rest area, there is no evidence of endangerment to public health and safety. The reliability of water in the area has been of some question and connection of the rest stop would bring public water in close proximity of subdivisions currently on central well systems that have expressed concerns about reliability. RFrOMMF.NT)ATION: This is a very unique yet potentially precedent-setting consideration. The sewer connection aspect seems to deserve particularly careful consideration in that, while not meeting the Comprehensive Plan intent for such service in the Rural Area, it is to address existing waste disposal problems in the Rivanna Reservoir watershed that can only be expected to increase in volume unless the facilities are shut down and waste flow ended. Short of alternative non-discharge systems which still involve some pump and haul, connection to public sewer seems to be the preferable way to address these problems. For this reason, it is recommended that this aspect of the request proceed to public hearing for sewer to existing structures only. In the interim, further information should be provided regarding the feasibility of alternative non-discharge systems. Regarding the request for water, the necessity for public water does not seem to exist based on information provided to this point. Should the Board decide to proceed to public hearing for this request, it should be for water to existing structures only. Verification of existing well flow and information on alternative well site potential should be provided. Regarding the rest areas, the Board may also want information regarding the feasibility of re-locating them closer to public utilities near the Crozet interchange. cc: Taylor Turner, III, R.

These facilities were constructed with Federal assistance and major improvements are normally performed on a cost share basis. One of the Interstate Highways (I-64) crosses the southern portion of Albemarle County. Two (2) rest stops are located along this portion of 1-64- one on the west bound lane (WBL) approximately 1 .4 miles west of the Ivy exit and one on the east bound lane (EBL) approximately 0.2 miles west of Route 691 .' These rest areas provide tourists and travellers the opportunity to break from their travels and use the rest room facilities. Governor George Allen has stated the interstate rest areas are a key to Virginia's tourism since they create the tourist's first impression of the state. Therefore, the overall appearance and cleanliness of the rest areas is an important part of promoting tourism in Virginia. EXISTING SYSTEM - DESCRIPTION Sewage handling is provided at each of the Albemarle County rest areas by zero discharge mineral oil systems. Oil transports the waste material from the rest rooms to a separate facility for separation of the oil and waste matter. The solids are held in a sludge tank and transported to the County wastewater treatment plant (wwtp) several times each week. EXISTING SYSTEM - PROBLEMS The mineral oil systems were manufactured by a subsidiary of the Chrysler Corporation which is no longer in business. The systems have experienced numerous problems over the years. The problems include inadequate filtration of the recycled oil, odor, aesthetics, incompatibility of the mineral oil with system components, capacity limitations, and limited availability of spare parts. As system demands increase during high usage, the filtration system efficiency decreases. The poor efficiency of the filtration system results in recycling of fecal matter, which results in odors and unsanitary conditions. Incompatibility of the mineral oil with the system components has resulted in deterioration and replacement of the plumbing on three occasions. 1 The EBL rest stop is approximately 3.4 miles from the end of the Crozet Interceptor. The WBL rest stop is approximately 1.5 miles from the Crozet Interceptor. EXISTING SYSTEM - ATTEMPTS TO REMEDY PROBLEMS The systems were originally installed in 1979. A complete overhaul was performed in 1988, at which time the largest possible system was installed. In addition, VDOT has replaced the plumbing three times with different type materials due to deterioration by the mineral oil. EXISTING SYSTEM - FLOWS The average daily flows (1994) were 19,904 gpd for the EBL and 20,266 gpd for the WBL. The maximum day flows were 60,080 gpd and 53,933 gpd respectively. VDOT estimates traffic on 1-64 to increase approximately 69% by the year 2015. Therefore, the corresponding estimated average flows are 33,638 gpd and 34,250 gpd respectively with maximum day flows of 101,535 gpd and 91,147 gpd respectively. ALTERNATIVE SOLUTIONS Three alternatives were considered for alleviating the current problems - Natural Treatment methods, Conventional wastewater treatment plants (wwtp),and discharge into the Crozet Interceptor. Natural Treatment systems are land application methods which include spray irrigation, rapid infiltration overland flow, and systems such as aquatic ponds, constructed wetlands, and other aquatic plant systems.2 The severe ground slope and the soils prevent the use of natural systems at the WBL rest stop. The ground is more gently rolling at the EBL rest stop. However, the slope, depth to rock, moderately permeable clayey subsoil, and seepage are the main limitations of the soils for natural treatment systems at the EBL rest stop.3 Construction of a conventional wwtp is feasible. However, the discharge will flow into the watershed management area which is contrary to the efforts by the County to eliminate point source discharges. The third alternative, discharge into the Crozet Interceptor, is the preferred alternative. This would allow conversion of the rest areas to a conventional wastewater system, keep all discharges out of the watershed management area, and allow for a cleaner more sanitary rest area. This would also provide additional revenue for the County in the form of a connection fee and in monthly treatment fees. It is noted, water is also required at the WBL rest stop with any of the conventional 2 Natural treatment systems as stated in the Virginia Department of Health Sewage Collection and Treatment Regulations, VR 355-17-120 Article 15- Natural Treatment Systems. Page 357-378. 3 The soils in the vicinity of the EBL rest stop include Ashe Loam, Braddock Loam, Chester Loam, and Thurmont Loam. Soil Survey of Albemarle County, U.S. Department of Agriculture, Soil Conservation Service, 1980. Pages 16, 17, 19, 20, 30, 118. alternatives. The capacity of the EBL well is 72 gpm based on a 48 draw down test.4 While additional storage capacity may be required, this well appears capable of meeting the demands. The reported capacity of the WBL well is 15 gpm.5 The 2015 average day demand is approximately 24 gpm at each rest stop, with maximum day demands of 71 gpm, and intermittent peaks greater than 71 gpm. Therefore, the WBL well is not capable of meeting the average demands. COMMENTS ON THE ALBEMARLE COUNTY COMPREHENSIVE PLAN The above alternatives were reviewed based on the Comprehensive Plan. Chapter Two of the Comprehensive Plan states: "Residential development in the rural portion of the County has adverse effects,.... Commercial land uses in the rural areas also impact agricultural and forestal activities. "5 The VDOT rest stops are existing state owned and state maintained facilities. The sludge produced by these facilities is currently treated at the Charlottesville wwtp. Therefore, modifications to these systems do not conflict with the stated objective of protecting the County's agricultural and forestal lands but rather support the County's objectives.' Chapter Two of the Comprehensive Plan also states: "WA TER RESOURCES GOAL; Protect the County's surface water and groundwater supplies for the benefit of Albemarle County, the City of Charlottesville, the Town of Scottsville, and downstream interests. "8 Both natural treatment methods and conventional wwtps could impact the water quality of the watershed management area. While the distance of the facilities from the water withdrawal is significant, point discharges are contrary to the County's long term effort to eliminate point source discharges.

I ' would minimize risk of contamination to the watershed management area. Chapter Three of the Comprehensive Plan states: "OBJECTIVE: Provide public water and sewer services to the Urban Area and Communities. STRA TEGIES: • Follow the boundaries of the designated Growth Areas in delineating jurisdictional areas. • Only allow changes in jurisdictional areas outside of designated Growth Area Boundaries in cases where property is: (1) adjacent to existing lines; and , (2) public health or safety is endangered. • Prohibit access to the Crozet Interceptor between the boundary of the Crozet Community and the Urban Area. "9 Regarding the first point, both rest stops are outside of the jurisdictional area and therefore are not part of the designated growth area. However, these are existing VDOT facilities which have attempted to provide their own water and sewer since inception. They do not represent growth in the rural area and they are not associated with residential or commercial facilities. Regarding the second point, the WBL rest stop is not adjacent to, but is close to the existing jurisdictional area. The EBL rest stop is not adjacent to the existing jurisdictional area. However, there is a public health issue associated with both of the existing facilities as previously noted. Regarding the third point, both rest areas are outside of the Crozet Community. The Comprehensive Plan also states: "The Urban area interchanges, ..., serve as gateways to Charlottesville and the urban area and deserve particular attention to desirable visual impact. i1° This is consistent with the Governor's statement. The rest areas provide the first impression to travellers of the Charlottesville area. Therefore, it is beneficial to Albemarle County and Charlottesville to assist VDOT in alleviating the current problems. The wording and intent of the Comprehensive Plan appear directed at limiting growth 9 The Comprehensive Plan for Albemarle County, Virginia 1989-2010, Adopted July 12, 1989, Department of Planning & Community Development.

I of residential and commercial development which could have an adverse impact on the environment. The VDOT rest stops are existing facilities, not new development. The force main and water line for the EBL rest stop would be located in VDOT right of way, to the extent possible. Constructing the water and sewer lines for the WBL in cross country easement is preferred due to cost. Water and sewer lines for both rest areas would be sized for VDOT use only. An agreement can be drawn to stipulate no additional connections are allowed. VDOT would own and maintain the lines and pump stations. REQUEST Based on the above stated problem, the implications of this problem, and the alternatives available, the Virginia Department of Transportation respectively requests an amendment to the Service Authority Jurisdictional Area to allow discharge of the rest stop wastewater into the Crozet Interceptor and connection to public water as needed.

This alignment follows the west bound lane of 1-64 to Route 637 and then north along Route 637 to its intersection with the Crozet Interceptor (See attached map). This alignment, while longer, has two advantages over the initial alignments. First, the pump station costs (equipment and power consumption) would be less due to the substantially lower static head.

PETRINI, EXECUTIVE DIRECTOR A g7 SUBJECT: REQUEST FOR JURISDICTIONAL AREA DATE: OCTOBER 24, 1995 The Rivanna Solid Waste Authority (RSWA), at their October 23, 1995 regular meeting, has directed me to proceed with a jurisdictional area request for the Ivy Sanitary Landfill located at 6876 Dick Woods Road, Charlottesville, VA 22903. This request is for a sewage force main that would run from the landfill to the Crozet sewage interceptor. As addressed in the accompanying memo from Joyce Engineering (our consultant), the health and safety of the area will best be served by a pump station and force main. Per our conversation with R. Stuart Royer & Associates, Inc., which firm is representing the VDOT Rest Stop Modifications, the RSWA would like to process its request along with the VDOT request. Both projects could use part of the same route and therefore some economic savings could occur. Equally important would be the acquisition and/or use of existing right-of-ways once instead of twice. Please call me should you require further information. ADP/ldb PRINTED ON RECYCLED PAPER 'y 10.44H[1 JUYLLt ENGINEERING P. 1/2 4 ' . a Memorandum To: Art Petrini - Rivanna Solid Waste Authority From: Ron DiFrancesco - Joyce Engineering Inc. Date: October 18, 1995 Subject: Jurisdictional Area designation for the Ivy Sanitary Landfill This memo addresses the reasons why the Ivy Sanitary Landfill property should be considered a Jurisdictional Area by the Albemarle County Planning Commission. This request is a result of the meeting which we attended on Monday, October 16, 1995, at the County's Planning Department. In an effort to plan for a long-term solution for leachate management at the Ivy Sanitary Landfill, the Rivanna Solid Waste Authority (RSWA) is requesting consideration as a Jurisdictional Area so that a possible future connection to the Crozet Interceptor can be made. The RSWA is considering and evaluating several long-term solutions to leachate management at the Ivy Sanitary Landfill. These solutions include, but may not be limited to, the following: 1. Transport by pump station and force main to the Crozet Interceptor. 2. Transport by tank truck to the Rivanna Wastewater Treatment Facility. 3. On-site treatment of leachate with a point source discharge to an adjacent stream. 4. In-situ treatment of contaminated groundwater through bio-remediation. The first option may be the most attractive solution. By installing a pump station and force main, the RSWA will be able to safely transport leachate through the County to the Rivanna Wastewater Treatment Facility for ultimate treatment and disposal. We feel this option may be feasible if the RSWA is able to join with the proposed VDOT Rest Area Improvement Project to install a parallel force main connecting to the Crozet Interceptor. However, it is our understanding that the Ivy Sanitary Landfill must first be designated as a Jurisdictional Area. This request is primarily based upon the following concerns relating to public health and safety Page 1 of 2 VCT 1a '35 10:45RM JOY( ENGINEERING P 2/2 '- .1 with the remaining options. The second option, which is currently being used, has the associated risk of transporting leachate via tank truck over interstate highway. The current transport vehicle has already been struck once by a motorist. It is our opinion that continuing this practice will present a greater risk to the public than transporting leachate through a buried force main. The third option of on-site treatment of leachate may be the most expensive and controversial. This would include a state-of-the-art treatment process with a point source discharge. The facility has already come under scrutiny relating to the state waters surrounding the facility. This option would require a Virginia Pollutant Discharge Elimination System (VPDES)permit. At this time, it is uncertain if this permit would be obtainable from the Department of Environmental Quality (DEQ) or if the RSWA could feasibly treat the leachate to desirable discharge limits. The fourth option of in-situ treatment of groundwater through bio-remediation is limited to the treatment of groundwater. This does not account for the leachate currently being collected and stored through the leachate collection and removal system. This option would have to be used in conjunction with one of the others to treat and dispose of leachate generated at the facility. Although this technology may prove to be safe and effective in treating groundwater, it does not solve the long-term problem of disposing generated leachate. At this time, the RSWA is requesting the Jurisdictional Area designation so if the solution of transporting leachate via force main is determined to be the safest and most cost effective, approval will have been granted so the Authority may design and construct the transport system. Please review and contact me if you have any questions or need additional information. Thank you. Page 2 of 2 / ATTACHMENT C COUNTY OF ALBEMARLE "1 2 3 1995 Ack MEMORANDUM TO: Wayne Cilimberg - Planning & Community Development FROM: David Hirschman - Water Resources Manage 60—, DATE: October 20, 1995 RE: VDOT Jurisdictional Area Request I spoke with Ron Conner of the Virginia Department of Health (VDH) in Lexington about this request. He had an interesting spin on the issue. Apparently, back in the 70s, VDOT had a. discharge certificate to put in package plants at the rest areas. Due to all the efforts to restore the South Fork Rivanna Reservoir at that time, the Health Department basically told them they needed non-discharging systems. Mr. Conner said that VDH couldn't at that time support point source discharges at the rest areas when all the efforts had been expended, through the Crozet Interceptor and other means, to remove existing point source discharges in the rest of the watershed. In that sense, VDOT was trying to comply with reservoir protection ideals by installing the mineral oil systems in the first place. There are only two locations in Virginia where rest areas have mineral oil systems: Albemarle County and New Kent County. Mr. Conner did not have much good to say about these systems. They have had problems with odors, leaking valves (and oil getting on the floor - a health hazard in itself), and many maintenance headaches. He also said that these systems are probably nearing their useful life expectancy. Apparently, VDOT is just doing what they can to keep these things going, but they aren't operating as designed. I discussed the following alternative solutions with Mr. Conner: 1. Construct Alternative Zero-Discharge System: There are some systems that recycle wastewater. However, Mr. Conner suggested that these need a complete treatment plant on-site and are very operator-intensive, not to mention expensive. They require careful signage to separate potable water from recycled wastewater. Most likely, the operation of one of these plants would also entail the periodic hauling of sludge. The public safety of a system like this depends heavily on the reliability of the operator and the smooth operating of the plant. 2. Spray Irrigation: This probably wouldn't (and shouldn't) be permitted because it's still a discharge in the reservoir watershed. .1 MEMORANDUM Wayne Cilimber, Planning & Community Development October 20, 1995 Page Two 3. Package Plants: Mr. Conner said VDH probably wouldn't recommend that a permit be granted because of the reservoir issue. VDH would probably tell VDOT to just limp along with the current system (if no other alternatives existed). 4. Mass Drainfield: There is too much flow at the facilities and the soils aren't suitable. If reservoir protection was the guiding principal when the mineral oil systems were developed, it seems that this philosophy should prevail to decide what should replace the faulty systems. The only alternatives to hooking to the Interceptor that respect this are: an on-site recycling plant, permanent pump and haul, or spray irrigation on land outside the reservoir watershed (this would also entail hauling of waste on County roads). It is my opinion that pipelines are much preferable, from a public health and safety point of view, than hauling waste around the County in tanker trucks. This reasoning eliminates pump and haul and spray irrigation. While Mr. Conner did not sound optimistic about the feasibility of a recycling plant, perhaps this alternative should be explored a little more thoroughly. I discussed this with Taylor Turner III of R. Stuart Royer and Associates, and he may be looking into it. It will be particularly important to evaluate whether these systems (1) require the hauling of sludge, and (2) pose operation and maintenance issues that diminish their attractiveness. Let me know if you need any additional information at this time.

It is my understanding that their application has been amended and they now seek water and sewer to existing structures for the westbound facility and sewer only to existing structures at the eastbound rest area. The Service Authority offers the following comments. Sewer Our engineering staff sees no technical problems with VDOT connecting to the Crozet Interceptor. If approved by the Board of Supervisors, VDOT would have to design, install, and operate at its expense all facili- ties from the rest area to the interceptor. Connection would have to be made at a point acceptable to this authority and Rivanna Water and Sewer Authority. The effect of these connections on the capacity of the interceptor is insignificant. You and I have discussed the prospect of VDOT building sewage treatment plants at these facilities if they are unable to connect to public sewer. Allowing that to happen would be contrary to one of the primary purposes for the Crozet Interceptor - ELIMINATION OF POINT SOURCE DISCHARGES FROM THE WATERSHED. Water Water service could be provided to the westbound lane rest area. The connection point would be at the intersection of Route 250 and West Leigh Drive. In studying the question of water service to this rest area, you should know that there are several existing subdivisions now served by central well systems which could potentially be served by further extensions of a water main which would serve VDOT. These are Peacock Hill, Langford Farm, and Glenair. Residents of Peacock Hill and Glenair have previously expressed concern about the reliability of their water systems and have made inquiries to ACSA about the possibility of service.

Date: 1 1/17/95 Re: VDOT Rest Areas - Albemarle County RLE: C:\WPDCOSIVADOT\9618\VWCMEM PURPOSE The purpose of this memo is to address comments stated in the Executive Summary presented at the November 1 , 1995 Board of Supervisor's meeting and to provide additional information to the Board of Supervisors. These items include Alternatives, Relocation of Rest Areas, Sanitary Conditions, and Water Request. SUMMARY AND RECOMMENDATION Various treatment systems including Conventional, Natural, Innovative, and Off-Site were reviewed in an attempt to determine cost effective, feasible alternatives for replacing the current VDOT Rest Area wastewater systems. Conventional wastewater treatment is not recommended due to the requirement for discharge into the watershed management area and high present worth cost. Land application is not possible due to soil conditions, bedrock, and potential for run off into the watershed management area. Natural systems (constructed wetlands,etc) are not recommended due to the requirement for a discharge and additional land requirements. Innovative systems (recycle-reuse) are not recommended due to the requirement for a discharge, pump and haul for sludge disposal, and the high present worth cost. Connection to the Crozet interceptor avoids discharge to the watershed management area, eliminates the potential for contact with recycled wastewater, and provides the lowest estimated present worth of the alternatives reviewed. Therefore, based on the above, connection to the Crozet Interceptor is the recommended alternative to alleviate the situation at the VDOT Rest Areas. DISCUSSION OF ALTERNATIVES There are two methods to handle wastewater from any facility- on site and off site treatment. On site treatment methods include conventional wastewater treatment systems, natural treatment systems, and innovative treatment systems. Off site treatment utilizes a public wastewater system. Transport of wastewater to a public system is accomplished by piping (force main and or gravity sewer).' Conventional Treatment Conventional treatment, while possible, requires discharge of treated wastewater into the watershed management area. A discharge into the watershed management area is contrary to the Comprehensive Plan and County efforts to eliminate all point source discharges. VDH stated they would oppose a discharge at either Rest Area.2 Therefore, conventional wastewater treatment is not recommended. 1 As per conversation with Mr. Ron Connor, Virginia Department of Health (VDH). Pump and haul is not allowed by VDH as a long term alternative. 2 Various conversations with Mr. Ron Connor, Lexington Office, VDH. RE JR R. Stuart Royer&Associates I' Natural Treatment Natural Treatment includes spray irrigation and systems such as aquatic ponds, constructed wetlands, and other aquatic plant systems.' The severe ground slope and the soil types prevent the use of natural systems (spray irrigation and land application) at the WBL rest stop. The slope, depth to rock, moderately permeable clayey subsoil, and seepage are the main limitations for natural treatment systems (spray irrigation and land application) at the EBL rest stop.' Aquatic ponds, constructed wetlands, and other aquatic plant systems require a discharge permit. Therefore, Natural Treatment systems are not recommended. Innovative Systems Innovative systems include those systems referred to as zero discharge and recycle-reuse. All recycle-reuse systems identified require off-site sludge disposal and a discharge permit for at least 5% of the wastewater flow. Therefore, there are no true zero-discharge or 100% recycle systems capable of meeting the demands of the VDOT Rest Areas. As requested, innovative/alternative systems were researched to determine availability and applicability. This research included calls to the Virginia Department of Health (VDH),6e the National Science Foundation (NSF),' the National Small Flows Clearing House (NSFCH),8 the National Park Services Albemarle County,10 manufacturer's representatives, manufacturers," 3 Natural treatment systems as stated in the Virginia Department of Health Sewage Collection and Treatment Regulations, VR 355-17-120 Article 15- Natural Treatment Systems.

VDH is opposed to a discharge at either Rest Area. VDH supports connection to the Crozet Interceptor.13 The National Science Foundation (NSF) stated they were not aware of any alternative systems suitable for the VDOT Rest Areas.14 NSF developed a standard (NSF 41) to address public health issues associated with potential public contact with the recycled water in recycle-reuse systems.15 NSF stated there are no recycle-reuse systems certified NSF 41 . Most systems certified NSF 41 are for flows less than 1 ,500 gpd and are either chemical or compost toilets.18 The National Small Flows Clearing House (NSFCH) was contacted regarding alternative/innovative treatment systems for remote facilities. A periodical search was performed resulting in seven (7) articles addressing zero discharge or recycle-reuse systems." 18 19 20 21 22 23 There were only four different systems identified in the seven papers.

Rr JR 4 R. Stuart Royer&Associates I' papers addressed VDOT's Fairfield/18 1 Rest Area.24 25 26 Two additional papers addressed the same system.' 28 Each of the systems required some form of treatment prior to recycling the water with discharge of at least 5% of the treated wastewater. In addition, each of the systems required vehicular transport (pump and haul) of the sludge and in some cases for wastewater also. Most of the systems appear to operate satisfactorily for small systems (less than 3,000 gpd) that can be cleaned frequently. However, their application for larger systems such as Rest Areas is not proven.29 VDOT Recycle-Reuse Additional information is provided on the VDOT(1-81)recycle system due to Albemarle County staff interest. The basic components of this system include rest room facilities, treatment,30 recycle pumping, sludge holding, and discharge to stream or holding for pump and haul.31 The Fairfield Rest Area was converted from a 10,000 gpd extended air activated sludge system to a recycle-reuse system.32 Water can be recycled approximately 20 times without problems. While there was no reason given for the limit on recycle, it probably deals with the concentration of toxins.33 24 AWWA Research Foundation, No 19. 25 Parker, Clinton E. 28 Virginia Highway&Transportation Research Council. 27 Public Works. 28 Sylvester, Robert O. and Seabloom, Robert W. 29 One system, designed for flows up to 3,000 gpd, involved flushing into nylon filter bags.This was a research project. The authors stated the system was worthy of further consideration and evaluation. This system requires pump and haul or treatment of wastewater and solids disposal. A second system utilized physical, chemical, and biological processes with equalization, gross particulate removal, trickling filter, screening, filtration, activated carbon adsorption, disinfection, and storage tank. System requires pump and haul of sludge. The basic system capacity is substantially less than required by the Rest Areas.The system included a sewer system to transport wastewater to a remote tertiary wwtp with discharge by spray irrigation. Contact was attempted through PA Directory Assistance and WEF Buyer's Guide Yearbook. It is assumed this company is out of business. A third system, typically used on aircraft, utilized recycle with a holding tank. Based on information in paper,the rest areas would require cleaning every four(4)days with pumping and hauling at this time. The authors stated, "Operation of present day wastewater treatment units in a recycle system is not considered practicable for Rest Areas." The VDOT system is addressed in the body of this report. 30 Treatment includes biological process, filtration, and disinfection. 31 This system started with a VPDES Permit which has been cancelled due to low wastage rates. 32 The recycle-reuse system was placed in service in 1978 after five years of bench scale testing. The extended air treatment system is still required to treat the wastewater prior to recycle. 33 1 1/2/95 conversation with Tom Bruursema, Program Manager, NSF. Rr JR R. Stuart Royer&Associates The system operates on a preset volume of water. Therefore, water is wasted as needed to maintain the desired amount of recycle water.34 Water is released to an evaporation/holding pond. Sludge (15,000 gallons per year) is transported from the pond to a conventional wwtp for treatment. The estimated present worth cost of a similar new system is $3,000,000. This is three times the present worth of connecting to the Crozet Interceptor ($1,000,000). This system requires a discharge permit and pump and haul of sludge to the Charlottesville wwtp.36 VDH is not supportive of this system.3e Therefore, this system is not recommended. The National Park Service(NPS)was contacted due to their extensive knowledge of alternative wastewater treatment systems.37 NPS has over 3,800 water and sewer systems across the country. NPS was not aware of any feasible alternative systems and stated, under the circumstances in Albemarle County, connection to the public system was the best alternative.3e Based on our research, Zenon Municipal Systems Inc. appears to manufacture one of the better recycle systems. However, a discharge is required with this system.39 The Zenon system is a recycle system (90-95%)with biological treatment and membrane filtration. VDH stated one of the Zenon Systems is operating in Virginia.40 We note, NSF stated there are no NSF 41 certified recycle-reuse treatment systems.41 The NSF 41 certification is not critical but does address health and safety issues associated with recycle systems. The approximate present worth of constructing one Zenon system ($2,000,000)is twice that of connecting to the Crozet Interceptor($1,000,000).42 Based on the requirement for a discharge permit, pump and haul, and high cost, the Zenon System is not recommended. 34 To account for the addition of wasted potable water from sinks and water fountains. 35 A VPDES Discharge Permit is required at startup. 3e 1 1/1/95 call to Mr. Ron Connor, Lexington Office, VDH. Mr. Connor stated the Fairfield Rest Area wwtp is not desirable. 37 11/3/95 call to Mr.Tom Harrington, Technical Expert Environmental Engineering for the National Park Service, Denver, Colorado. 38 Mr. Harrington stated alternative systems are used when public sewer is not available. Mr. Harrington worked with the experimental mineral oil system installed at Mt Rushmore. This is the same system installed in Albemarle and New Kent. Mr Harrington stated the problem with this system is the coalescing filter. 39 As per conversations with Mr. Ed Jordan, President and Mr. Herschel)Winfrey, V.P. Engineering and Operations, Zenon Municipal Systems, Inc. 40 11/3/95 call from Mr. Don Alexander, Richmond Office, VDH. There is a Zenon system installed in Great Falls, Virginia that appears to operate satisfactorily. It has a drain field for disposal of the treated wastewater. 41 1 1/2/95 call to Mr.Tom Bruursema, Program Manager, NSF.

However, the Albemarle County Service Authority (ACSA) stated, "there are no technical problems with VDOT connecting to the Crozet Interceptor" and "the effect of these connections on the capacity of the interceptor is insignificant."43 A possible location for connection to the water system was also provided." Connection to the Crozet Interceptor is the most cost effective alternative identified. It allows conversion of the Rest Areas to a more reliable system, maintains the County's position of No Discharges into the watershed management area, and allows for a cleaner more sanitary Rest Area. This alternative also provides additional revenue for RWSA in the form of monthly treatment fees. We recommend sewer and possibly water for existing VDOT structures only. The lines would be sized for existing Rest Area structures only and no other connections would be allowed. Connection by others to this line would adversely impact operation of the VDOT system. RELOCATION OF REST AREAS The construction cost associated with relocation of the Rest Areas is approximately $5,000,000(+) per Rest Area. Relocation to an interchange is potential competition with (preset or future) private businesses. As per FHWA and VDOT guidelines, Rest Areas are to be located where they would not compete with private businesses. Relocation of the Rest Areas does not eliminate the need for water and sewer. In addition, it would be difficult for VDOT to justify to the taxpayers why they relocated two Rest Areas two miles to connect to public utilities. Therefore, relocation of the Rest Areas is not feasible. SANITARY CONDITIONS The current mineral oil treatment systems were originally installed as experimental systems to assist Albemarle County eliminate point source discharges into the watershed management area. These systems were overhauled in 1988 and the largest possible systems installed. The mineral oil is not compatible with the various piping materials installed.45 The oil deteriorates the piping, fittings, and valves resulting in leaking. Major leaks have occurred requiring shut down of the Rest Areas and disinfection prior to opening. WATER REQUEST As stated in the Executive Summary, there is no endangerment of public health associated with the well system at the WBL Rest Area. However, the need for water at the rest areas is due to the fact conventional wastewater systems require water to operate. Our statement of inadequate water supply was originally based on discussion with RSWA, water demands at the WBL Rest Area, and low reported WBL well capacity. However, it is supported by ACSA's comments regarding capacity problems at Peacock Hill, Langford Farm, 43 10/20/95 letter from Mr. Bill Brent to Mr. V. W. Cilimberg 44 10/20/95 letter from Mr. Bill Brent to Mr. V. W. Cilimberg 45 The piping in the rest areas has been replaced three times with different materials. Rom' JR R. Stuart Royer&Associates and Glenair which are adjacent to the WBL Rest Area.ae The capacity of the EBL well is 72 gpm (based on a 48 draw down test).47 The reported capacity of the WBL well is 15 gpm.48 The 2015 average day demand is approximately 24 gpm at each rest stop, with maximum day demands of 71 gpm, and intermittent peaks greater than 71 gpm.49 Therefore, the WBL well is not capable of meeting the average day demands of a conventional system. A draw down test to determine actual WBL well yield is currently being performed. It is VDOT's intent to provide water from the site if possible - whether from the existing or new wells. Conversion to low flush toilets and urinals is recommended. This reduction in demand combined with an actual well capacity greater than previously reported should satisfy the water requirements. However, if water is not available in sufficient quantity, connection to public water is recommended. IMPACT ON TOURISM The director of the local Board of Tourism stated the rest areas do have an impact on public perception. If Rest Area aesthetics are poor (ie odors, unclean, etc),tourists immediately form an opinion of everything in the state including the Charlottesville area. If bad odors are present, everything is considered dirty, regardless of appearance.5o ae 10/20/95 letter from Mr. Bill Brent to Mr. V.W.

COUNTY OF ALBEMARLE ,.iv- MEMORANDUM TO: Wayne Cilimberg - Director of Planning & Community Development FROM: David Hirschman - Water Resources Manager Nt____ DATE: November 27, 1995 RE: VDOT Jurisdictional Area Request, Alternatives Assessment I have reviewed the additional materials submitted by R. Stuart Royer & Associates, Inc. concerning wastewater alternatives for the Rest Areas. I feel that the applicant has undertaken a fair assessment of the available alternatives. While alternative zero-discharge systems may be an attractive idea in some cases, it seems that the volume of flows, natural topography and soils, and the desire to eliminate any point source discharges from the reservoir watershed limit their feasibility for the Rest Areas. This leaves connection with the Crozet Interceptor as the technical alternative that is most consistent with watershed protection policies (see my October 20 memo to you for more details). With regard to the request for water for the WBL Rest Area, there is not currently enough information available to evaluate the request. Of particular importance for this analysis are: the capacity of the existing wells, opportunities for new wells, opportunities for storage to help meet peak demands, and the influence of water-conserving fixtures on demand projections. In other similar situations, such as the Clifton Inn, the applicant has exhausted reasonable on-site solutions in order to justify the need for public water from a public health and safety standpoint. Please let me know if you need additional information at this time. DJH/ctj Ric davidIdoe2.n . 271995 NOV 29 ' 95 13 : 04 • PAGE . 002 4` I ATTACHMENT IV R. STUART ROYER & ASSOCIATES, INC.

Based on the information which you transmitted to me by letter dated November 17, 1995, it appears that service of the referenced facilities by connection to the Crozet Interceptor is the alternative we would consider most desirable. Of course, this conclusion assumes that the need for continued operation of the rest areas has been adequately justified. Connection to the Crozet Interceptor is consistent with long standing agency preferences to: 1. Avoid the construction of several smaller wastewater treatment facilities where regional sewerage and central treatment are feasible, 2 . Avoid pump and haul of liquid wastes where other options are reasonably available, and 3. with particular reference to the South Fork Rivanna River Reservoir discharge area, protect the primary water supply for Charlottesville and the surrounding Albemarle County service area by elimination of contributing point source discharges through central connection. The Crozet interceptor was a grant participation project and undertaken for this purpose. FILL'i. Ctst a NOV 29 ' 95 13 : 05 PAGE . 005 Mr. Taylor F. Turner, III, P.E.
