11 1. INTRODUCTION Lombardo Associates, Inc. (LAI) has been contracted to develop wastewater management solutions to achieve water quality standards to protect the environment and public health in Canaan Valley. As part of continuing wastewater planning efforts LAI has reviewed existing information to assess the condition of the wastewater treatment facilities (WWTFs) and onsite septic systems and define the wastewater needs in the Valley. This report is a summary of the best available information gathered for this phase of the project. Review of parcel information indicates that about 50 percent of the parcels in Canaan Valley are currently developed. The existing wastewater management practices in Canaan Valley consist of small WWTFs or package plants and onsite septic systems. There are seventeen WWTFs operating in the Valley. These WWTFs serve an estimated 60 percent of the current development. It is estimated that there are approximately 367existing onsite septic systems in the Valley. Table 1-1 presents the breakdown of the number of parcels in the wastewater service area for each WWTF and their development status.

12 1.1. Sewered Areas Overview Figure 1-1 shows the locations of each facility. A summary of the permit, flow, collection system, treatment system, discharge, and operation and maintenance (O&M) practices for each of the facilities is provided in Table 1-2. A more detailed breakdown of the treatment system components is presented in Table 1-3. A summary of the discharge locations for the WWTFs is provided in Table 1-4. The majority of the sludge from the WWTFs is transported and disposed of by Western Maryland Septic. This company has a permitted sludge processing facility where lime stabilization and land application are utilized to dispose of the sludge. Table 1-5 summarizes the quantity and frequency of the pumpouts during 2004 and All of the WWTFs in the Valley are permitted under the National Pollutant Discharge Elimination System (NPDES) program. The permit limits for each facility are presented in Table 1-6. The most stringent ammonia-n limit is 2 mg/l for Timberline Resort and Windwood and Talheim Village. The lowest dissolved oxygen (DO) concentration allowed is 6 mg/l. Compliance with the NPDES permits from 2003 through 2005 from review of the discharge monitoring reports (DMRs) is summarized in Table 1-7. In December 2004 WVDEP served almost all of the WWTFs with Administrative Consent Orders (see Table 1-8) to bring the facilities into compliance with their discharge permits. Wastewater collection and treatment improvements are a first step in the restoration of the water quality of the Upper Blackwater River. The extent of inflow and infiltration (I/I) in the collection systems was evaluated based on available information, site visits, and conversations with the WWTF operator. No field data collection activities were performed. This screening evaluation indicated that the Canaan Valley State Park (CVSP) Campground facility and the Land of Canaan Homeowners Association (LOCHOA) facility have excessive I/I. The other systems have varying degrees of I/I and the existing information is not sufficient to quantify it. Sewer system evaluation studies (SSES) are required for all systems to properly identify the quantity and location of the I/I. These studies are best performed during the spring when groundwater is high. Table 1-9 summarizes the estimated extent of I/I and the resources available for evaluation. All of the aforementioned information was reviewed and in conjunction with site visits to assess the condition and needs of the WWTFs. Table 1-10 presents a summary of this assessment. All of the facilities are almost 20 years old or older. The structural condition and instrumentation and control deficiencies are also presented. The operation and maintenance (O&M) procedures for the various WWTFs in Canaan Valley include the following: Visual inspection of water clarity, settling and sludge levels Settleability tests as needed if an observed problem does not have a simple solution Adjustment of the RAS rate if needed Scheduling of sludge pumping when needed Adjustment of aeration chamber timing if necessary PAGE 2

13 Inspection of UV system and replacement of lamps as needed Check supply of chlorination and dechlorination tablets Pump maintenance as needed Inspection and cleaning of sand filters, where present Record pump run times Sample when necessary Measure or estimate effluent flow Visually inspect conditions of the polishing ponds where present It should be noted that CVSP and Timberline are not participating in this project to the same extent of the other facilities. The Department of Natural Resources has retained Woolpert Engineering to prepare a detailed Facilities Plan for the State Park facilities. Their plan will not be done prior to the completion of this project and thus, will not be integrated at this time. Similarly, Timberline Resort had Thrasher Engineering prepare plans and specifications for a membrane bioreactor system to replace their existing facility and bring their facility into compliance. Timberline Resort provided limited information on their facility late in the LAI s planning process, and that information has been incorporated into the Decentralized Wastewater Facility Plan to the extent possible.

Influent flow meter * Not participatin in Study. Data is taken from discharge permit applications, inspection reports and has not been field verified Unsewered Areas Overview All of the development outside of the sewer service areas in the Valley is currently served with onsite septic systems. It is estimated that there are about 370 onsite systems in the Valley. Per the County Health Agent, there is a low failure rate for onsite systems in the Valley. However, the inventory of existing onsite systems in the County is inadequate for the proper management of onsite systems. A key element to the success of the onsite component of any wastewater management plan is proper management and oversight. At a minimum, all onsite systems in the County should be brought up to level 1 management model from the USEPA s Voluntary National Guidelines for the Management of Onsite and Clustered Wastewater Treatment Systems, which requires an inventory of systems. It is vital to know how many systems there are, where they are located, and what condition they are in. Septic systems are permitted and regulated by the Tucker County Health Department. All of the County Health Department s files are currently hard copies only. There is no way to track a given septic system. Common problems that are encountered include: PAGE 12

23 1. There is no unique identifier used to track a system. Thus, in some cases multiple permits have been issued for a single system since there is no way to connect permits for upgrades with the original permit that was issued for that system. 2. There is no method of spatially locating the permitted systems. The files are not tied to any other County database. 3. System addresses/locations are not provided in a consistent manner. LAI recommends that an inventory and database for tracking and monitoring onsite systems be developed and implemented by the County Health Department. Large septic systems may also be permitted by through the underground injection control (UIC) program. There are no existing UIC systems in Canaan Valley. However, permits have been issued for 10 systems to serve future development on a total of 55 properties in the Black Bear and Timberline subdivisions. PAGE 13

However, based on the aforementioned, it is likely that the WWTF is close to 20 years old Collection System The collection system consists of the following components: Six manholes 850 LF of 8 PVC Treatment Facility PAGE 15

26 The Beaver Ridge facility is a 30,000 gpd packaged extended aeration treatment plant that utilizes sand filtration for tertiary treatment. There is no flow equalization at this facility. The treatment plant consists of the following components: o bar screen o 32,580 gal aeration chamber with 1,500 gallon aerated sludge holding tank o 7,270 gal clarifier o 1,352 SF sand filter o Post-aeration chamber o UV disinfection Figures 2-1 and 2-2 show the treatment facility and discharge locations, respectively. Figure 2-3 presents the process flow diagram for the facility. FIGURE 2-1: BEAVER RIDGE FACILITY FIGURE 2-2: BEAVER RIDGE DISCHARGE PAGE 16

28 2.2.3 Effluent Dispersal Effluent from the treatment facility is discharged to an unnamed tributary of Flat Run (approximately 0.02 miles from its mouth), a tributary of the North Branch Blackwater River. The discharge goes to a culvert that goes under the street. The tributary appears to be approximately 600 feet from the edge of the road, across an open field. There is no visible stream that carries effluent across the field and into the tributary. The coordinates of the discharge are as follows: N W Sludge Management Sludge is pumped directly from the aeration basin, just behind the baffle wall that separates it from the clarifier. The aerated sludge storage tank is not currently being used. Sludge is pumped approximately 2 to 4 times per year, when the operator determines it is needed. Table 2-2 lists the quantities and frequency of the pumpouts during 2004 and TABLE 2-2: BEAVER RIDGE SLUDGE PUMPOUTS WWTF Liguid Sludge (gal) 2004 Frequency of Removal (#/yr) Dry Sludge (tons) Liguid Sludge (gal) 2005 Frequency of Removal (#/yr) Dry Sludge (tons) Beaver Ridge Resort System Deficiencies Treatment Facility Deficiencies This facility has no flow equalization, a critical component for systems with highly variable flow rates. There are no flow measurements and no controls to allow for pacing RAS flow rates based on the influent flow rate. Sludge wasting is not easily achieved with the undersized sludge holding tank and is not currently being done on a regular basis. The following issue has been noted on past DEP inspection reports: Scum on the clarifier This facility is over 20 years old and the original equipment is still in use. Therefore, the remaining useful life of this treatment facility is limited Collection System Deficiencies PAGE 18

29 The operator reports some I/I that appeared following a new development. Previous to the new development, the operator did not observe any I/I Compliance and Regulatory Issues Discharge Monitoring Reports Summary A review of regulatory compliance based on DMR data from 2003 to 2005 is summarized in Table 2-3. Graphs showing permit compliance for Beaver Ridge WWTF are located in Appendix A1. TABLE 2-3: BEAVER RIDGE RESORT WWTF REGULATORY COMPLIANCE SUMMARY Parameter No. Months with Exceedence Total Flow ph BOD TSS Ammonia-N Fecal Coliform Total Enforcement Actions On December 20, 2004 Beaver Ridge Owners Association was issued Administrative Order No for numerous effluent violation from the first quarter of 2001 through the third quarter of On February 15, 2005, the President responded that they have started to add Microbe- Lift IND in the plant and pond to help control algae, BOD, and nitrogen. They also started adding Floc-cite [Mg(OH)2] to help prevent odors and increase settling during high flows. Additionally, the plant operator stated that the problems occur when the sand is dirty or frozen in the bad weather Capital Improvement Plan There are no known upgrades planned for either the collection or treatment system at this time Needs Definition The Beaver Ridge facility is operating near the end of its useful lifetime. As part of a long-term wastewater management plan, it is not advisable to upgrade this plant. The PAGE 19

30 following upgrades would be necessary to make the facility current with best management practices for extended aeration systems: Install a new flow equalization tank Install a new aerated sludge holding tank Install a new influent flow meter and RAS flow meter Replace RAS pumps and fit with VFDs or control valves to allow for pacing against influent flows Replace sludge wasting pumps, valves and piping to sludge holding tank PAGE 20

There are no flow measurements and no controls to allow for pacing RAS flow rates based on the influent flow rate. Sludge wasting is not easily achieved with the undersized sludge holding tank and is not currently being done on a regular basis. A polishing pond is currently used as a tertiary treatment step. This is not a preferred method of tertiary treatment, as polishing ponds are subject to numerous disturbances that can inhibit treatment. Factors such as weed covering or ice and snow cover will inhibit or prevent sunlight from entering the system. This results in a lack of treatment and can cause septic conditions. No aeration is provided in the pond. No deficiencies were noted by the DEP inspector on inspection reports from May and December of This facility is approximately 20 years old and the original equipment is still in use. Therefore, the remaining useful life of this treatment facility is limited Collection System Deficiencies PAGE 26

TABLE 10-3: CANAAN MOUNTAIN RESORT REGULATORY COMPLIANCE SUMMARY Enforcement Actions Parameter No. Months with Exceedence Total Flow ph BOD TSS Ammonia-N Fecal Coliform Total On March 12, 2004 a Notice of Violation was issued as a result of the aforementioned February 16, 2004 compliance inspection. On May 13, 2004 WVDEP personnel met with representatives from North Lake LLC in a pre-enforcement meeting. Discussion included the need for the following actions to avoid further enforcement actions. More maintenance on the de-chlorination tubes Increased attention to solids management, especially in the contact chambers Cleaning and adding new sand to the sand filters Record keeping at the facility for all maintenance performed Electric light installed in the sand filter room for safety and proper maintenance On December 20, 2004 North Lake LLC was issued Administrative Order No for numerous effluent violation from the first quarter of 2001 through the third quarter of On January 19, 2005, North Lake LLC appealed (Appeal No EQB) the Order requesting a motion to dismiss on the basis that all of the items discussed during the May 13 th meeting were addressed and there have been no violations since the corrective measures were implemented. On January 21, 2005 the evidentiary hearing for the Appeal was continued until March 10, PAGE 84

95 According to WVDEP, North Lake LLC did not follow through with the Appeal and thus is no longer in the appeal process Capital Improvement Plan It is unknown at this time if there are any planned upgrades to the collection and treatment systems Needs Definition The Canaan Mountain Resort facilities were not inspected. Data from permit applications and inspection reports were used to make the assumptions for this section. The North Point facility is operating near the end of its useful lifetime. As part of a long-term wastewater management plan, it is not advisable to upgrade this plant. The following upgrades are assumed necessary to make the North Point facility current with best management practices for extended aeration systems: Install a new flow equalization tank Install a new aerated sludge holding tank Install a new influent flow meter and RAS flow meter Replace RAS pumps and fit with VFDs or control valves to allow for pacing against influent flows Replace sludge wasting pumps, valves and piping to sludge holding tank The North Lake facility is a newer installation. The basic components of this facility should have sufficient remaining useful life to make upgrading potentially feasible. No specific information on this facility was collected as a part of this report. PAGE 85

101 TABLE 11-2: TIMBERLINE RESORT WWTF REGULATORY COMPLIANCE SUMMARY Parameter No. Months with Exceedence Total Flow ph BOD TSS Ammonia-N Fecal Coliform Total Enforcement Actions On December 20, 2004 the Timberline Four Seasons Resort was issued Administrative Order No for numerous effluent violation from January 2003 through July On February 16, 2005, the Timberline Four Seasons Resort responded stating that they have retained Thrasher Engineering to review treatment alternatives. They are in the process of reducing I/I in the system. Thrasher Engineering determined that membrane filtration is the best option for Timberline. Accordingly, Timberline proposed a schedule for design and implementation of a membrane filtration system with an estimated completion date of May Capital Improvement Plan Timberline has retained Thrasher Engineers to design a membrane bioreactor (MBR) treatment system to replace the existing facility. The equipment cost for the MBR system is estimated to be $521,600 and installation of the equipment should total $1.2 to $1.5 million. It understood that the total construction cost of the project is $1.7 to $2.0 million. The WWTF upgrade consists of an influent pump station and MBR system. The MBR system consists of the following: Fine screen 14 membrane modules concrete tankage 2 grinder transfer pumps 2 permeate pumps 2 backpulse pumps 3 blowers 1 recirculation pump and flow monitoring system 1 backpulse tank 1 membrane cleaning system 1 ph control system 1 steel bioreactor tank PAGE 91

102 The MBR system will be house in a concrete block building with a asphalt shingle roof. Also included are the necessary site work, piping, concrete, electric, and mechanical work necessary for the upgrade. The upgrade also includes converting the existing aerated lagoons into equalization ponds. Approximately 30 days of detention is provided in the ponds at the peak flow of 120,000 gpd. This will allow Timberline to treat flows in excess of the 120,000 gpd Needs Definition The useful lifetime of an aerated lagoon system is not easily defined, therefore the remaining useful life of this facility is unknown. Lagoon facilities are not a reliable treatment option due to climate conditions during the seasonal high flow period and the high potential for upsets associated with this type of treatment. As part of a long-term wastewater management plan, it is not advisable to upgrade this plant. Review of water use data (see Table 11-3) indicates that existing flows appear to be approximately 50 percent of the permit limit.

103 and future development. The design flows for the existing and future development were estimated to be about 147,000 gpd and 97,000 gpd respectively. Thus, it appears that the future development will increase wastewater generation by approximately 65 percent. Experience has shown that actual wastewater generation is about 50 percent of the prescriptive design flow. Based on actual water use, it appears that the buildout could occur without additional discharge capacity. However, this evaluation is based on: 1. No allowance for I/I. In this situation the "value" of I/I removal could be very high as it could potentially eliminate the need for additional discharge capacity. 2. Use of actual water use flows versus book design flow. This is common accepted practice when there is a substantial record of data. However it inherently states that intensity of use would not increase. PAGE 93
