WQ0004115 & NCO087106 Gentlemen: In accordance with the state of North Carolina's requirements, we are pleased to,attach three copies of our ;Wastewater System Annual Operating Performance Report for calendar year 2004. As indicated in this report, all property_owners of Champion Hills Golf Community will be notified of the report's availability through the March issue of the community's monthly newsletter. The.newsletter will state: The State of North Carolina requires all permittees for wastewater systems to make reports available to their users summarizing their systems' performance over the past twelve months. The purpose of this requirementls' to provide a mechanism for user oversight and, hopefully, instill confidence in the system and its operators. In addition, the State requires all permittees to adopt and implement a sewer ordinance for all users of the system.•The Champion Hills Sewer Ordinance was implemented on July 1, 1999 and is periodically updated as necessary. Both the Champion Hills' Performance Report for calendar year 2004 and the current Sewer Ordinance are now available from the Club office and can be obtained by either stopping in or by calling Jessica at (828) 696-1962 to receive copies by mail. Please advise if you have any questions or comments. Sincerely, Lee J. Weber Chairman, Champion Hills WWS Committee Cc. with attachment DENR-DWQ, Asheville, ttn. Mr. Roy Davis & Ms Beverly Price' I HAGEN DRIVE / HENDERSONVILLE, NC 28739-8964 / (828) 696-0928 / FAx (828) 696-2097 E-MAIL - championhills@cytechcis.net Champion Hills Property Owners Association Year 2004 Wastewater System Annual Report Applicable Permits: WQ0004115 & NCO087106 The Champion Hills Wastewater System is sanctioned by the North Carolina Department of Environment and Natural Resources - Division of Water Quality (NCDENR-DWQ) and. operates under Spray Irrigation System Permit WQ0004115 and National Pollutant Discharge Elimination System Permit NC0087106. These permits define the conditions under which the Champion Hills' Property Owners Association (POA) must operate the system and expose the POA to substantial fines if it does not comply. In 1999, the State of North Carolina passed legislation requiring all entities that own or operate wastewater treatment and collection systems to provide annual reports to their customers describing the systems and summarizing their performance over the past twelve month period. The purpose of this legislation is to provide a mechanism for user oversight and, hopefully, instill confidence in their system and its operators. This report for calendar year 2004 has been prepared in compliance with that legislation. Description of System: The Champion Hills' Wastewater System consists of three sub -systems: a Collection System, a Treatment System and a Disposal System. The Collection and Treatment Systems are owned and operated by the Champion Hills POA. The Disposal System is owned and operated by the Champion Hills Club under a formal Agreement with the POA. The Collection System consists of approximately 62,500 linear feet of eight inch diameter PVC sewer lines, approximately 480 manholes, 8 lift stations and miscellaneous items such as controls, standby generators, force mains, telemetry, spare parts, etc. As its name implies, the collection system collects the wastewater from the community and transports it to the treatment plant for processing. The Treatment System is located on a 2.86 acre plot adjacent to the 16`' fairway. It consists of a treatment plant, two lift stations, a 700,000 gallon lined effluent holding pond, a building housing various pieces of equipment & controls, and a standby generator. The operation of this system is subcontracted to a state -licensed operator, James and James Environmental Management. Under the terms of the permit, the operator must visit the facility daily (excluding weekends and holidays) and properly manage and document daily operations, including all testing, reporting and other permit requirements. The treatment plant is the "heart" of the Treatment System. It has a current throughput capacity of 70,000 gallons of wastewater per day, but is expandable to 140,000gpd. Raw sewage (influent) enters the plant at the Equalization Basin through a 4 inch line from an influent lift station. The Equalization Basin first serves as the primary settling tank where heavy solids fall out and then parcels the flow into two 35,000 gpd process trains, each consisting of an Aeration tank followed by a Clarifier. From the Clarifier, the partially processed sewage flows through a Filter and finally to a Chlorination Basin. The treated water (effluent) leaves the Chlorination Basin by gravity, flows through a dechlorination device, and then to a lift station where, during warmer months, is pumped to the 700,000 gallon membrane lined holding pond for eventual use in irrigating the golf course and, during colder months, is discharged directly to a nearby stream. The warmer month Disposal System is essentially a portion of the golf course irrigation system. During these months, effluent is pumped from the holding pond by the club's state trained and licensed irrigation system operators and applied to the golf course through "selected" sprinklers that don't permit runoff to nearby streams. The effluent irrigates the grass and then either evaporates or filters through the soil before entering the ground water system and streams. Most wastewater systems do not have the ability to perform this final filtering operation and, consequently, must discharge directly to waterways. Champion Hills' residents can be proud of this environmentally responsible way to use its effluent. Unfortunately, the golf course application procedure can be problematic during wet or colder periods when the ground is saturated, frozen or covered with snow. Recognizing the problems unique to mountainous locations, the State has granted us permission to discharge effluent to a nearby stream from November lst through April 30th. Our effluent, of course, is "treated household wastewater" and is of better quality than that which many municipalities and cities release directly to streams and rivers on a year round basis. As local streams have greater flow during winter months and as our community production of wastewater is lowest during that time of year, we are confident this procedure will have no harmful effect on the environment. We are also hoping the State will give us some relief to direct discharge in summer months on those few occasions when the golf course is saturated and the holding pond is full, We will be submitting a formal request to the State in the near future. 2004 Performance, Problems and Accomplishments: Operationally, 2004 was a relatively good year. Regrettably, however, we did have the following permit violations: Date Type of Violation Sample.Reading Max. Allowed 6/16104 Turbidity 17.2 NTU 10.0 NTU 6/17/04 Turbidity 17.3 NTU 10.0 NTU 6/19/04 Turbidity 10.3 NTU 10.0 NTU 7/8/04 Ammonia Nitrogen 8.7 mg/1 6.0 mg/l 7/8/04 Total Suspended Solids 15.3 mg/1 10.0 mg/1 7/26/04 Turbidity 15.0 NTU 10.0 NTU 7/27/04 Turbidity 15.3 NTU 10.0 NTU 9/8/04 Turbidity 15.1 NTU 10,0 NTU 9/9/04 Turbidity 15.8 NTU 10.0 NTU 9/10/04 Turbidity 39.8 NTU 10.0 NTU 9/17/04 Turbidity 23.9 NTU 10.0 NTU 9/18/04 Turbidity 24.0 NTU 10.0 NTU 9/19/04 Turbidity 25.0 NTU 10.0 NTU 9/20/04 Turbidity 18.9 NTU 10.0 NTU 9/28/04 Turbidity 20.1 NTU 10.0 NTU 9/29/04 Turbidity 30.4 NTU 10.0 NTU (Note: In all cases, the Monthly Average was compliant.) The foregoing Turbidity violations were all caused by storm water entering the system. Between June and September we received the remnants of several Tropical Storms and Hurricanes. Surface water poured down the mountainous terrain, flooding our manholes and entering the system. The plant could not process the excessive flows causing the effluent to exceed the permit's Turbidity requirements. This, of course is not good, but occasionally happens under such conditions. Most, if not all, treatment plants in the area at that time experienced similar problems and Western North Carolina itself was proclaimed a "Disaster Area" because of flooding. In December each year, your Wastewater Committee organizes a sewer line inspection team that walks the lines and looks for locations where surface or ground water might enter the system ("Inflow & Infiltration" as it is known in the industry). Andy Zima, Champion Hills' manager of maintenance, then reviews the committee's findings and makes all necessary repairs. Over the past five years, we have installed approximately 65 dishes in those manholes we think susceptible to seepage and have identified another 20 prospects for dishes this year. These dishes prevent surface water from entering through the manhole cover. We can never eliminate I&I altogether, but over the years we have.made great strides in reducing it and will continue this effort in the future. The Ammonia Nitrogen and TSS violations mentioned above were an indirect result of pump failures in the Equalization Basin. The pumps were restored and, within a reasonable period, the ammonia nitrogen and TSS were returned to compliance. We now carry a spare pump in inventory so the problem can be addressed quicker should it re -occur. We believe we have an excellent team between James & James running the treatment plant and our own Andy Zima managing maintenance and making repairs. Although we had these permit violations during the year, we doubt they could have been foreseen or prevented. All were acted upon promptly by our team and no fines were imposed by the State. Over the years, we have addressed many issues to help us perform better and continue to look for ways to improve: A. Although we have made significant progress in reducing "Inflow & Infiltration" (I&I) in our collection system during periods of heavy or extended rain, we continue to experience more than we would like. The quantity of I&I is probably not unusual for a system of our size in mountain terrain, but it does represent a significant portion of our treatment plant's capacity and can upset the treatment process as indicated earlier. If not curtailed, it could mandate that we prematurely expand the capacity of our treatment plant. Finding and correcting sources of I&I remains a priority of our operations. We have made good progress in past years and will continue these efforts in 2005 and beyond. The work involves getting out in the rain and noting where increased flow occurs in the system. We then look for possible sources and solutions which include raising manhole covers, realigning and sealing manhole frames, sealing manhole or lift station seams, fixing broken riser pipes, installing manhole dishes, etc. As previously mentioned, we also walk the entire sewer line annually, pulling all manhole covers, in search of I&I sources and other problems. In addition, we have recently purchased a portable flow meter that allows us to measure flows over short periods during and after heavy rains so we can determine what kind of storms affect us most. B. Power failures, which are not uncommon in the mountains, can play havoc with wastewater systems. Our system includes three permanently located standby generators that run on continuous supplies of natural gas. One is located at the treatment plant and the other two are at lift stations with streams nearby. For the remaining six lift stations, we rely on a portable diesel powered generator stored at the golf course maintenance building. All lift stations that rely on the portable generator have been equipped with "quick connection devices" to facilitate emergency usage. C. We now have telemetry at all eight of our collection system lift stations, as well as at the treatment plant. The telemetry automatically contacts our 24 hour Security service in case of power or pump failure. Security promptly notifies our emergency responders in order to prevent or limit raw sewage spills. The responders are on call 24 hours per day. . D. We have purchased a sewer camera with a TV type viewing screen and 200 feet of cable, which enables us to look into sewer lines to investigate internal problems. Should we find a problem that can't be corrected using a water jet or rotating auger inserted through a manhole, the camera will show us exactly where to dig the line. E. In 2004 we purchased a sludge digester tank to supplement the plants existing digesting capacity. The tank will be installed and put into operation in 2005. This additional capacity should allow us to substantially reduce the amount of sludge we must pay to have hauled to larger treatment facilities, such as Brevard or Hendersonville. F. During 2004, the Wastewater Committee prepared a five year Wastewater System Funding Plan for years 2005 through 2009. This plan reviews current funding levels and makes future projections for operating, maintaining and possibly expanding the wastewater system. In summary, the plan concluded we might have some modest fee increases over this time frame, but in general, the funds are all in good shape for the foreseeable future. G. While back -washing the Tertiary Filter this past year, we accidentally over- pressured the plate supporting the filter media, breaking it loose from its welded supports. We contracted with the original filter supplier to manufacture and install a new plate, after which we re -installed the plastic valves and provided new filter media. Although the entire process took a couple of months to complete, our plant operator was able to keep the effluent in compliance while the filter was down. To prevent this from reoccurring, we purchased a thicker media support plate and installed pressure gages and relief valves on the backwash pumps. H. In 1999, the Champion Hills POA developed, implemented and distributed a Sewer Ordinance for the community. The ordinance has recently been revised. Property owners wanting an updated version of this document should contact Jessica at the Club's Administration office. 4 Sewage Spills: The State requires that we notify it immediately of raw sewage spills of any size which reach surface waters (i.e. streams, drainage ditches, etc.) or spills of 1,000 gallons or greater that do not reach such streams or ditches. We are pleased to advise that we had no reportable spills in 2004.
