The fleet of participants came from all across the State of Tennessee as many of the anglers had never fished the waters of the Cumberland River. Tournament Coordinator, Dewayne Culpepper of TAUD, and Tournament Director, Kirk Smith of C.I. Thornburg Co. announcing the winners! At 5:41 am, the boats started their engines, Adam Sharp of Gladeville Utility District began to call each team number as they made their way past the starting buoy line and headed out onto the Cumberland River. The fleet of boats were an impressive sight and hinted of the inaugural tournament’s success. By 6 am, all boats had left the launch site and were fully engaged in finding that “sweet spot” or “honey hole” to land a limit of bass in hopes of winning the tournament. The Tournament Committee reassembled at the launch site around 11 am to check on and receive reports from select boats on the lake. Danny Lassiter of Gladeville Utility District, reported around 11:30 am that fishing was good, and that he witnessed a lot of anglers with measurable Bass. Tournament rules stated that each boat must check in at the check point no later than 2 pm. Tournament Coordinator, Dewayne Culpepper happily reported that no boats were declared late to the scales. As the anglers began loading their rigs and bringing the fish to the weigh-in, many assembled with great interest to see who would place and take home the Attorney Bob Parker for Harpeth Valley Utilities District proudly poses with his largest catch! Pictured right, his teammate, Thomas Lawrence. 6 TENNESSEE UTILITY NEWS Big Bucket of Cash for the Largest Bass. The Big Bucket of Cash pool reached $370. Assisting Tournament Official, Flipper Copeland, was: Jaimie Hanseroth of C.I. Thornburg Co., Nick Newman of MLGW, Ryan Fields of C.I. Thornburg Co. and Billy Heck of A.Y. McDonald Co. “We appreciate the volunteers who stepped up on tournament day to help,” said Kirk Smith, Tournament Director. “I also want to thank Colleen Sauve of TAUD for taking photos of the anglers as well as getting the information onto the TAUD Facebook page.” Patriotic boater passed by the boat slip. The Tournament Committee was assembled by anglers from Gladeville Utility District. After learning of their involvement in other organized fishing events, GUD’s Danny Lassiter and Adam Sharp were tabbed by Tournament Director, Kirk Smith. “This was just a natural fit to have them step up and help us get this program together,” said Smith. Penny Sutherland of Hartsville Water and Sewer assisted the committee and helped coordinate the Anglers Cookout held that night at the Ward Ag Center. This tournament would not have been possible without its sponsors.

An emergency locator was called, and after the utilities were located, they began an excavation. The excavation proceeded as planned. The operator excavated the site until the leak was visible. Once visible, it was determined the couplings used during the original valve replacement were leaking, and it would be an easy fix. The district employees felt that someone did not tighten the couplings enough, and they had shifted loose through time to develop a leak. The plan was to simply re-tighten the coupling bolts, backfill the site, and the job would be done. David Amburgey Old Hickory Utility District Have you ever been shocked or jolted while taking a drink from a water fountain, taking a shower or even worse, have you ever heard of a water utility operator being electrocuted while repairing a water main? It’s probably not something you think could happen, but the employees of The Old Hickory Utility District know the danger all too well. Following a Spring storm including hail, heavy rainfall and high winds, everything seemed normal at the utility district. The typical workday began, thankfully storm damage appeared minimal or so they thought. The district received a call from a customer stating that water was leaking in the street. The first thought was that this could not be a leak. The majority of the district’s leaks occur during the winter months, and the area had just been hit with heavy rainfall, so it was thought to be rain water. District employees investigated the call and indeed found water flowing out of a water valve box. This was odd due to the fact that the leaking valve wasn’t very old. The asphalt repair patch was still visible in the street from the valve installation. The employees continued with normal 3rd Quarter, volume 25 That wasn’t the case, and this is where the story takes a more serious turn. An operator got into the excavation site and examined the leak. In the process, he placed his hand on the water main and suddenly pulled it back. The operator stated he was shocked and that the water main was electrified somehow. The water operator exited the excavation and the local electric utility was called to investigate the area. After a quick investigation, the electric utility found nothing out of the ordinary and offered a pair of insulated gloves to use during the leak repair. While the insulated gloves were being located, the backhoe operator continued to excavate the site and clear more soil from the area near the water main. While in the process of clearing the site, the backhoe bucket came into close proximity with the main and an electrical arc shot from the main to the bucket. The electric utility was again notified that something was not quite right. About the same time a report came in that a cable tv repair technician was also shocked down the street. When this happened all work in the area was stopped by the electric utility until a more in depth investigation could be completed. During the investigation a fallen tree limb was discovered laying across the electric power lines about a block from the water leak. Apparently the tree limb had caused a hot electric line to come into contact with the neutral/ground line, which sends electrical current into the ground. Several residences had their electrical panels grounded to the internal plumbing system, and 13 this caused the electrical current to travel back to the water system mains. (see illustration I-A) The amount of electricity traveling through the water system was so significant, it actually melted the rubber gaskets in the repair couplings, which were used to install the valve. (see coupling photo below) Shortly after this incident, the district began to hear horror stories from customers who claimed they had been shocked while taking a shower. One customer whose water heater had not been working claimed to have hot water during this time. The district and electric utility were fortunate no employees or customers were injured or worst, killed during this incident. Illustrations A,C & D The utilities plan to use this experience to try and prevent this situation from happening in the future. The Old Hickory Utility District plans to implement new safety procedures to follow during leak repairs. One thing a water utility can do if it suspects the water main to have electric current is to first contact the electric utility and request the electricity be disconnected. If the electricity cannot be disconnected, a good procedure to use is to install grounding cables across two pieces of pipe before any pipe sections, meters, etc. are removed or repaired. (see illustration I-C & I-D) It is important that every repair be taken seriously. If something doesnâ€™t seem right investigation must follow. The safety of employees and customers comes first. Utilities must work together to determine the problem as well as the safest way to solve it. 14 TENNESSEE UTILITY NEWS Young Professionals: Jennifer Wood, E.I.T Interviewed by Tonia Pass Education Administrative Assistant What is your job title? Q: A: An engineer at Consolidated Utility District of Rutherford County. What are some of your daily/weekly duties? Q: A: I initially developed and currently manage our hydraulic model which includes running “what if” scenarios on new projects, identifying problem areas, running fire hydrant flow analyses, performing water age calculations, etc. I use this in coordination with our SCADA software to monitor the system and identify leaks and potential problem areas in our system. What drew you to this line of work? Q: A: To be honest, my aunt told me one day when I was in high school that she thought I would make a good engineer. I was good in math and science and thought “Hmm, maybe I would.” So, to engineering school I went. During college, I spent time in the different specialties of civil engineering either in the Jennifer Wood, E.I.T, Consolidated Utility District form of an internship or just in my studies and found that I was more of Rutherford County. interested in water than in buildings or roads. What is your educational background? Q: A: I received my Bachelor of Science in Engineering from UT Martin, and I am currently completing my Master of Science in Civil Engineering from the Missouri University of Science and Technology in Rolla, MO (formerly University of Missouri – Rolla). That is my background, but I believe education is a continual process. What did you want to be when you grew up? Q: A: I went through many stages. First, I wanted to be a pediatrician. To tell you the truth, I’m not entirely sure why I decided against that other than having to take anatomy and physiology. Next, because I participated in mock trial sessions in high school, I thought I may want to be a lawyer. History was low on my list of interests, so that was scratched off the list rather quickly. Because I was involved with my high school newspaper, I also thought about journalism. I realized I couldn’t just become an editor from the beginning which is the aspect I loved, so that too was crossed off the list. I loved numbers and science, so when my aunt introduced me to the idea of engineering, I reasoned that if I didn’t like it, I could always choose an alternate career path. As it turned out, engineering was the perfect fit. What do you love most about your job? Q: A: I love the fact that no two days are the same. The next new challenge is always around the corner—we may have a pump fail, a leak causing systemic problems, an unhappy customer, a new development wanting fire protection or uncharacteristic low pressure. A utility takes an entire team of people to solve problems, and I am happy to be a part of that team. 3rd Quarter, volume 25 15 16 TENNESSEE UTILITY NEWS What is your philosophy on work and life? Q: A: They are one in the same—I strive to be the best I can be while upholding my morals and values of a Christian woman. There are times I succeed and times I fail. Each success and failure teaches me something about myself. What community services do you involve yourself? Q: A: This is definitely an area I can grow in and expand. I have been involved with a program through the Boy Scouts of America, which gives high school students a look into career areas that they are interested. CUD is the host for the students interested in engineering. I am amazed at the low interest in math and science in regards to engineering. My husband and I also attend New Vision Baptist Church and try to be involved with the community in that aspect, from community help days to helping with Sunday school. Have you experienced any challenges upon entering the utility industry? Q: A: My first challenge entering the utility industry was that I knew absolutely nothing about it—I mean, zilch. I was fresh out of school with only the intern experience I gained on the consulting side of engineering. I was introduced to GIS, hydraulic modeling and what a tapping sleeve was all at the same time, which was definitely a challenge. Being a woman in a man’s world also has its own challenges, but I knew that going into engineering and the utility industry. The key is to be yourself and respect other people—you will gain respect from others in return regardless of gender. What do you consider your greatest accomplishment as a young professional? Q: A: I was honored to be one of the few selected to participate and graduate in the 2010 class of Leadership Rutherford. It was an eye-opening experience, and I recommend any professional in the Rutherford County area to apply. The knowledge and skill that I have gained in hydraulic modeling over the past couple of years is also an accomplishment I greatly value. What challenges do you foresee within the utility industry in the next 10 years? Q: A: The concern of all water utilities in the next 10 years is going to be water supply. The challenge that accompanies that will be how to solve the problem. This will take a tremendous unified planning effort from city managers and planners, utilities, elected officials, those who manage our water supply and customers. A city cannot build first then solve the utility problems second—a regional plan has to be a priority and a guideline for future development. What advice do you have for other young professionals considering working in the utility industry? Q: A: For someone who is still in school and considering the utility industry, I would suggest applying for an internship at a utility to gain experience. On the water utility side, I would recommend taking classes or continuing education in the areas of hydraulics, water treatment, etc. 3rd Quarter, volume 25 17 MIC in Fire Sprinkler Systems Jack Poole, PE and Michael Nightingale Poole Fire Protection This article is intended to serve as an introduction to Microbiologically Influenced Corrosion (MIC), what it is, how it is typically treated and what cross-connection control measures should be implemented. In general, the fire protection sprinkler industry does not consider corrosion as a significant issue to sprinkler systems. Sludge slime inside sprinkler possible MIC bacteria End of sprinkler pipe showing corrosion near the coupling MIC is defined as â€œa mode of corrosion Exterior sprinkler pipe corrosion Sludge slime inside pipe fitting cased from MIC - pinhole leak possible MIC bacteria incorporating microbes that react and cause the corrosion or influence other corrosion processes of metallic materials.â€? Microbial corrosion, or bacteria corrosion, is a form of corrosion that is caused or promoted by bacteria or microorganisms. MIC is not caused by a single microbe, but can be attributed to many different microbes or the reaction between different microbes. These different types of microorganisms live on the nutrients in the water or the pipe, and react with the products of other microorganism reactions and pipe material. MIC refers to corrosion and ensuring loss of metal caused by biological acid producing organisms. Generally, these microorganisms form colonies on the surface of a metal, producing slimes that collect and adhere deposits to the metal. Typically the entire surface, or at least the wetted surface, of metal sprinkler pipe is affected by general corrosion; however, MIC, on the other hand, is very localized. There are two classifications for the types of bacteria that cause MIC, aerobic and anaerobic. Aerobic type require oxygen in order to survive, whereas anaerobic do not. Upon filling the sprinkler system with water these bacteria are introduced into the piping system. While oxygen is still present in the water the aerobic bacteria begin to corrode the interior of the pipe. As oxygen is depleted the aerobic bacteria die off and the anaerobic bacteria continue to corrode the pipe walls. A common type of bacteria found in anaerobic environments is sulfate-reducing bacteria. Sulfate-reducing bacteria produce a sulfur acid, which can cause stress cracking. In the presence of oxygen, some bacteria directly oxidize iron-to-iron oxides and hydroxides, and other bacteria can react with the sulfur to produce sulfuric acid. During the lifecycle of a sprinkler system, water will be drained from, and added to, the piping system due to inspections, testing, and periodic maintenance. The addition of new water into the sprinkler system can revitalize the oxygen dependant aerobic bacteria, which can lead to accelerated corrosion. MIC feeds on the pipe materials which creates a nodule and a pit beneath the nodule. There might be only a few nodules or there can be many. Within these nodules microbes rarely work alone, but operate as a mixed community of differing types and groups. Bacteria cells often form 18 TENNESSEE UTILITY NEWS in the deposits of corrosion products, causing and enhancing their rate of corrosion and destruction. This corrosion and pitting will also decrease the flow characteristics of the water traveling through the pipe. Additionally, this can lead to rust that has the potential to plug sprinklers, valves and potentially cause blockage of the sprinkler pipe. It is estimated that approximately 20 - 40% of all sprinkler pipe corrosion problems are caused by aerobic and anaerobic bacteria. Dry pipe systems are not immune to the effects of MIC. The residual water, sometimes caused by condensation, which remains in fittings, drops, and trapped sections of pipe, suffer from corrosion. In many cases the corrosive effects are more acute in dry systems due the increased oxygen in the relatively empty (no water) pipe and fittings. National Fire Protection Association (FPA) 13, Standard for the Installation of Sprinkler Systems, requires the water supplies to be evaluated for the existence of microbes and conditions that contribute to MIC. When conditions are found that contribute to MIC, a plan shall be developed to treat the system by one of the following methods: • Install a water pipe that will not be affected by the MIC microbes. • Treat all water that enters the system using an approved biocide. • Implement an approved plan for monitoring the interior conditions of the pipe and established time intervals and locations. • Install a corrosion monitoring station and monitor at established intervals. NFPA 25, Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems, (2008 Edition), Section 14.2.1 requires “an inspection of piping and branch line conditions shall be conducted every 5 years by flushing connection at the end of one main and by removing a sprinkler toward the end of one branch line for the purpose of inspecting for the presence of foreign organic and inorganic material.” The following Section 14.2.2, requires that if tubercles or slime is found, a sample shall be tested for indications of microbiologically influenced corrosion (MIC). Detection methods for MIC include pinhole leaks, visual inspections of debris and plugging inside the pipes, coloration or smell of the stagnant water, and water testing by a microbiologist or metallurgical engineer. Currently there are several methods to combat the MIC problems. These include chemical treatments, flushing, mechanical cleaning, and pipe replacement. It is important that these sprinkler system cross-connections are assessed • TANK RENOVATIONS • STATE REQUIRED INSPECTIONS • ROBOTIC UNDERWATER INSPECTIONS • MAINTENANCE PROGRAMS • REPAIRS - LADDER GATES 297623_brown.indd 1 3rd Quarter, volume 25 8/31/06 3:14:59 PM 19 to determine the level of hazard present to determine the correct level of backflow protection to be provided. It is known in the Cross-Connection Control industry that a standard wet-pipe sprinkler system (without any chemical additives) is typically protected with a doublecheck backflow prevention assembly. However, if the sprinkler system has been chemically treated for MIC, it is important to utilize a reduce pressure principle type backflow prevention assembly to protect the crossconnection to the drinking water supply. Several chemical treatment systems are commercially available to treat MIC in fire sprinkler systems. Some of the companies that sell MIC treatment systems include: • Huguenot Laboratories – Port Jervis, NY • fpsCMI – Saint Louis, MO • Potter Corrosion Solutions – Hazelwood, MO • Liberty Corrosion Solutions – Mesquite, TX The International Plumbing Code (2006), Section 608.16.4.1 states: “Additives or non potable source. Where systems under continuous pressure contain chemical additives or antifreeze, or where systems are connected to a non potable secondary water supply, the potable water supply shall be protected against backflow by a reduced pressure principle backflow preventer.” To minimize the risk of MIC entering the potable water a backflow prevention assembly should be required. When chemicals are used to treat or reduce the impact of MIC a reduced pressure principle backflow prevention assembly is required to be installed. Once a backflow prevention assembly has been installed on the sprinkler system, NFPA 13 requires that means for forward flow testing shall be provided on the system. Often a backflow prevention assembly will remain in the closed position until the system is inspected, tested or maintained, which is typically annually. Depending on quality of the water, some deposits or calcium may build up on the internal components of the backflow prevention assembly, which may not allow it to fully open in the event of a fire, causing inadequate water supply to the sprinkler system. Therefore, this forward flow testing is intended to exercise the internal components of the backflow prevention assembly. The minimum flow rate required by NFPA 13 to achieve this forward flow testing is the demand of the sprinkler system. This includes hose stream 20 demand if the facility is provided with standpipes. In summary, we now understand that MIC is a process which involves bacteria that can accelerate corrosion in fire sprinkler systems, causing pinhole leaks or obstruction to the flow of water through the pipe and sprinklers. MIC is typically treated chemically by a biocide, and when this chemical treatment is implemented, reduced pressure principle backflow prevention assemblies should be installed to protect the public water supply. Furthermore, it is understood that when a backflow prevention assembly is installed on the sprinkler system, means to achieve a forward flow test shall be provided to make sure the assembly is exercised so it will open fully when needed Reprinted from “ABPA News Magazine”, January/February 2011 Issue, Copyright 2011 by The American Backflow Prevention Association . PO Box 3051 . Bryan, TX 77805-3051 . 979.846.7606, used by permission. Additional notes from Brent Ogles, TAUD Education Manager One method to reduce the damage caused by MIC is frequent flushing. While this may improve water quality inside the fire sprinkler system, it increases the amount of unaccounted for water for the water system. Since fire sprinkler systems are often unmetered, the systems have no record of this unauthorized water use. Where excessive unaccounted water use is suspected, efforts should be made to monitor water use. It should be noted that NFPA standards are only enforceable if a state or other governing body adopts them. If these NFPA standards were enforced at the State level in Tennessee, it would be through the Department of Commerce and Insurance, the Division of Fire Protection. It does not appear that this office is requiring the evaluation and remediation plan addressed in the NFPA standards relating to MIC but they have stated in an email that it is the owner’s responsibility to mitigate MIC. TENNESSEE UTILITY NEWS 3rd Quarter, volume 25 21 Is Flushing Wasteful? Tony Wyatt TAUD West, TN Field Supervisor Routine flushing of water mains can be controversial in many water systems. Operators know that it is a necessity to provide clean safe water to their customers and to meet water quality parameters. Some customers object when water from flushing floods their yards, gardens, etc., while others complain when sediment or air shows up in their water from lack of flushing. Utility officials or mayors may comment that flushing water onto the ground is a waste of water and therefore a waste of money. Occasionally these officials have stopped operators from routine flushing. So, what do the rules say about the kind of flushing program that a utility must have? 1200-5-1.17(10) All community water systems having more than 50 service connections shall establish and maintain an adequate flushing program. The flushing program established shall help ensure that dead end and low usage mains are flushed periodically, drinking water standards are met, sediment and air removal and the free chlorine residual specified under Rule 1200-5-1.17(4) is maintained. Records of each flushing are to be maintained by the water system. These records shall include date, time, location, persons responsible and length of flushing. In addition to the above information, the free chlorine residual will have to be measured and recorded on the end of dead end mains after being flushed. The rule above indicates that the purpose of the flushing program is to provide a safe high quality water supply to the utilityâ€™s customers. Air and debris can enter and accumulate in a distribution system. Disinfectant residuals can deplete due to low usage and chlorine demand in the water lines. Disinfectants may also combine with materials in the system to form undesirable byproducts such as trihalomethanes. An adequate flushing program can correct each of these situations. But what constitutes an adequate flushing program? Is once a year sufficient to maintain a desirable water supply or do you need to flush more often? This depends on several factors such as the 22 layout of your distribution system. A system with long mains with few customers may require more frequent flushing to maintain the required chlorine residual or prevent the buildup of disinfection byproducts. The type of pipe in the distribution system and the water quality can also be factors that affect the need for increased flushing. Many distribution systems are well served by a systematic flushing of the entire distribution system once or twice per year. A systematic flushing consists of starting at the source, whether it is the treatment plant, master meter or a tank, and flushing hydrants and blow-offs along the main until the end of the main is reached. In this type of flushing, debris or air that is not completely removed at one flush point will be drawn along the main until it is removed at the end. Systems that have loops may require that valves be closed to create dead ends to flush toward. This type of flushing must be conducted at adequate velocities to scour the inside of the main, breaking debris free to be flushed out of the main. This cannot be accomplished with a 3/4â€? tap on a large line or simply cracking a hydrant open and leaving it running for several hours. The Design Criteria for water systems has this to say about blow-offs and flushing velocities: 9.0.3 Dead Ends b. Where dead-end mains occur they should be provided with a fire hydrant, when fire flows are available, or blow-off for flushing purposes. The blow-off shall be at least 2 inches in diameter, but should provide flushing velocities of 2 feet per second or greater. In addition to the routine flushing mentioned above, most systems require more frequent flushing of problem areas such as dead-ends where debris collects more often or low usage areas where the chlorine residual is difficult to maintain. Some systems have areas that may require TENNESSEE UTILITY NEWS flushing weekly or more often. In these cases where frequent flushing is necessary to maintain water quality, an automatic flush valve may be beneficial. These valves can be set to flush for a predetermined time in the middle of the night when customers will not notice. Additional flushing is often required following the repair of water mains when debris or air has gotten into the line. While there is no “one size fits all” flushing program for every distribution system, customer complaints, chlorine residuals and disinfection byproduct levels can be good indicators of the effectiveness of your program.

F. Alan Shirk A.Y. McDonald Inc. dictated by the Safe Drinking Water Act of 1975 (amended 1986 and 1996). For more than two decades, the manufacturer of waterworks brass, plumbing products, pumps, water systems, high-pressure gas valves and meter bars has focused on perfecting its lead-free line of waterworks brass products and educating its utility customers, distributors and others about successfully complying with the new Federal Reduction of Lead in Drinking Water Act going into effect January 4, 2014. The state of California has been a leader in the effort to make no-lead brass the industry standard. Los Angeles became the first city in the country to transition to no-lead brass, for which A.Y. McDonald provided the industry’s first no-lead brass corporation and curb stops. A.Y. McDonald is headquartered in Dubuque, Iowa with a major distribution center in Elizabethton, Tenn. President Mike McDonald, whose great-great grandfather founded the business in 1856, said the new law reduces the allowable lead content of any water system component that comes into contact with potable water to a weighted average of only 0.25 percent. “This is a bulldozer coming down the road. It is a major change. As one of the first manufacturers in the industry to offer a complete line of no-lead valves and fittings, A.Y. McDonald has been researching and preparing for this legislation for more than two decades. Our job is to educate,” he stressed. Lead content in drinking water has long been a concern of industry, government and environmental organizations because of the metal’s harmful effects to the human nervous system and brain development. Until the latest law, however, the maximum allowable lead content of drinking water pipes and fittings has been 8 percent, as 28 A.Y. McDonald Marketing VP Scott Knapp said California set the tone for the nation in 2006, when Governor Arnold Schwarzenegger signed Assembly Bill 1953, reducing the maximum allowable lead content of plumbing pipes and fixtures to a weighted average of 0.25 percent. Already the industry leader in no-lead service brass. “California set the tone for the industry,” said McDonald, “and because we had taken a proactive approach in developing no-lead products long before the legislation passed, we were prepared for the increased demand when the state law went into effect. Now we’re prepared and excited for the increased demand on a national scale, including throughout Tennessee.” Knapp said the new Federal law is mostly based on the California legislation which went into effect January 1, 2010. Vermont enacted its own “0.25” law which went into effect the same date as California, while Maryland begins enforcing its law January 1, 2012. However, beginning in 2014, all states will be required to comply with the new Federal law. A few problems occurred in California that Tennessee TENNESSEE UTILITY NEWS could avoid in 2014. According to Knapp, “There was a lot of confusion about what exactly had to be done, how to dispose of inventory, who was covered. One person said, ‘I don’t need it, I’m with the government.’” Knapp said that on January 1, 2014, the sale of valves, fittings and fixtures with a weighted average lead content of more than 0.25 percent will be prohibited for any use with potable water. “That means if you are caught with a large inventory, you cannot install it or sell it to anyone,” Knapp said. McDonald said manufacturers, utilities, distributors and others have to “back up the entire distribution chain to the manufacturer, who is the first line of defense.” For example, after June 2013, A.Y. McDonald may no longer guarantee delivery of leaded waterworks brass products. That gives us time to flush our own inventory. “A proactive utility will start a day before we do. In fact, if I was a water utility, I would convert right now,” said McDonald. Developing a lead-free product required a lot of experimentation with alloy formulations and processes, said A.Y. McDonald Engineering VP Steve Tefft. meet the requirements of UNS Copper Alloy C89833 per ASTM B584-09a, in addition to being ANSI/NSF 61 and 372 certified. For more information, visit A.Y. McDonald’s special website (www.noleadbrass.com), the company website (www.aymcdonald.com), or e-mail sales@aymcdonald. com. “Our waterworks brass products currently contain nominally 85 percent copper, 5 percent lead, 5 percent tin and 5 percent zinc. We could not reduce copper content due to corrosion concerns and wanted to keep tin content high for added strength and corrosion resistance. We had some margin with zinc, but did not want to increase its percentage content. We experimented with various percentages of bismuth, which is next to lead on the Periodic Table, to replace lead, which helps provide pressure tightness in castings and good machining characteristics. “ Once we had a workable formula, we went through a lot of casting and machining tests, and corrosion studies. The bottom line is our lead-free products perform equally to our traditional leaded products,” Tefft said. All A.Y. McDonald no-lead waterworks brass products 3rd Quarter, volume 25 29 Update on TAUD & TDEC Committee to Develop Regulatory Guidance for the Cross Connection Control Program Brent Ogles TAUD Education Manager Early in 2011, TAUD formed an ad hoc committee to discuss TDEC’s requirement of the 5% inspection of unprotected residential connections. The committee’s charge was later expanded to draft regulations, related policy and guidelines relating to the Cross Connection Control Program. The committee is composed of members from Knoxville Utilities Board, Memphis Light Gas and Water, West Wilson Utility District, Warren County Utility District, Harpeth Valley Utilities District, TDEC and TAUD. The committee met in February, March and most recently in June. Before any state administered program can be effectively developed, it must be addressed in statute (or law) to authorize what it strives to do. Statute generally specifies what is required or prohibited and Regulations expound on how these specifics are accomplished. Statutes are voted on by our Legislature and when codified are referred to as TCA (Tennessee Code Annotated). Regulations are promulgated by the Division administering the statute. The Division of Water Supply has authority over water systems and the Cross Connection Control Program and promulgates regulations as needed. Currently, statutes say only that cross connections are prohibited and not much else. Regulations currently place the responsibility of establishing and maintaining a cross connection program on the water system by requiring the development and adoption of an ordinance or policy, and approval of a plan. Once approved by TDEC the items in the ordinance/policy and plan establish the specifics by which the water system is evaluated. In other words, if the ordinance/policy or plan says that the water system will do a certain activity and it doesn’t, then that is considered a deficiency as viewed by the Division of Water Supply. Tennessee’s Cross Connection Control Program has operated this way since its beginning and continues to operate the same today. There are some aspects of the Cross Connection Control Program that the committee felt should be established and administered directly by TDEC. That means that TDEC would interact directly with the issue or the person and not involve any water system. These are items that should be consistent and applicable to all water systems and having them directly under the authority of TDEC would provide uniformity across the state. These items are: • Develop and provide a list of approved assemblies • Establish a degree of hazard listing and corresponding protection needed • Develop and administer a uniform assembly test procedure • Establish a tester authorization process • Develop and require a uniform written and practical examination process 30 TENNESSEE UTILITY NEWS â€˘ Establish minimum training requirements â€˘ Establish minimum trainer requirements TDEC is willing to develop Rules and administer these items; however there is a concern that statutory authority does not exist to support this. The Environmental Health Act, which authorizes the certification of water, wastewater, distribution and collection operators, deals only with those certifications and no other. It makes no provision to include any additional certificates such as cross connection. The Safe Drinking Water Act provides authority to regulate water systems but does not lend itself to regulating individuals. The idea of amending either of these statutes is something that most consider better left alone because in doing so, it opens up the statute to changes that could be detrimental to the program. The committee has requested that TDEC, Office of General Counsel-Environment look at the SDWA and consider its authority over that portion of the draft rules that deal with TDEC non-system authority. Initially, the primary focus of the Committee was a Division of Water Supply inspection requirement of 5% of the unprotected residential connections. During the most recent meeting, the committee reviewed a concept offered by one of the members that incorporated a point weighting system for activities that hone in on those residential connections that have the highest probability for cross connections. The proposal established a minimum inspection amount of one percent with not more than half of the one percent coming from the weighted activities. The committee requested that the Division of Water Supply consider that proposal. Future progress of the committee will greatly depend on a positive response to the request and the proposal mentioned above. 3rd Quarter, volume 25 31 Upcoming Classes - TAUD Training Station Here’s a look at classes being offered for August through December 2011.

The utility district served a complimentary lunch, gave presentations about the district’s history and the evolution of operations, lifetime goals as well as responsibilities and led facility tours. Officials 1 in 12/16/2010 12:55:32 PMwere attendance County Mayor Larry Waters, Pittman Center Mayor Glenn Cardwell, Gatlinburg Chamber of Commerce Executive Director Vicki Simms, Congressman Phil Roe and Senator Doug Overbey. Roe congratulated WCUD on a job well done. “Without potable water and sewer treatment, it’s an economic issue,” he said. “(This infrastructure) creates jobs. You have made this region of the country much better. Thank you for what you’ve done.” Overbey also had nothing but praises for the district and its employees. “We love what you’re doing,” he said. “The ability to attract industry and economic growth (relies on) water and sewer utilities. Thank you for your service.” Because of their high-level of commitment WCUD won best discharge water in their region, two years in a row. The utilities wastewater treatment plant operator, Vickie C M Y CM MY CY CMY K 34 TENNESSEE UTILITY NEWS James does an out standing job of operating this very complex plant. “We’re very proud of our staff and board of commissioners. They’re doing a fantastic job,” said WCUD Board President, Robert Vick. Another source of pride for WCUD is their wastewater system, which has no impact on Congressman, Phil Roe the environment. “A small group of people are in charge of a big responsibility — protecting the environment,” Vick said. “(The water is) trout stream quality. It takes the raw sewage and cleans it enough to discharge it into a trout stream. We had a great lunch over looking the mountain stream. There are not many sewer plants where you can do that.” said Vick. “It’s good to highlight the dedicated people who make it happen,” he added. One person who has been with the utility since it begun is Delmer Ball. He served for thirty years, and he now serves as the utility’s board secretary. “We all try to work together,” WCUD District Manager James Sunstein said. “It takes everyone to keep it going. It’s difficult sometimes, but we’re doing the right thing. I like having a part in taking care of the environment. I’m proud of our system.” Janice Carver, WCUD office manager did an excellent job of putting together this event along with maintaining her daily duties. WCUD has a dedicated staff, which contributes to its success. Congratulations WCUD for a fantastic 30 year celebration!

Box 2529 Murfreesboro, TN 37133-2529 www.taud.org Not only are we a rural water tank supplier, we are a rural water customer. Built in 2005 Built in 1991 Our Water Our office Supplying and building a tank is one thing. Getting to drink your water from it is another. We were fortunate to be able to build our new office in an area served by a member of the Tennessee Association of Utility Districts. Gladeville Utility District has three Aqustore® tanks on their system, which also serves our new headquarters. There is a reason Aquastore glass-fused-to-steel tanks are considered the premium tanks on the market versus concrete or welded steel. The glass panels that make up an Aquastore tank are chemically inert, impermeable, nonporous and more hygienic than uncoated steel or concrete. They do not deteriorate, corrode, stain or fade. And they never need repainting! Southeastern Tank, Inc. supplies the best tank for TAUD water systems and is proud to have its water supplied by a TAUD water system.
