SOURCE PROTECTION PLAN The Drinking Water Source Protection Plan for East Grouse Creek Water Pipeline, Co., heretofore referred to as EGC Pipeline, is available for your review. It contains information about source protection zones, potential contamination sources and management strategies to protect our drinking water. EGCW Pipeline utilizes two ground water sources, Buckskin Spring and the North Well. Buckskin Spring is identified as a remote and protected area and has a low level of susceptibility to potential contamination sources. EGC Pipeline has identified contamination sources within a two-mile radius of the North Well in general terms which are of greatest concern, such as septic tanks, roads, residential areas, industrial areas, etc. Our source(s) have a low (Buckskin Spring) to medium (North Well) susceptibility to potential contamination from outside the distribution system. We strive each year to develop even better management strategies to further protect our sources from contamination. Please contact us if you have questions or concerns about our source protection plan. Most likely source of potential Main Distribution Line Contamination is your service line. During our most recent Sanitary Survey, conducted 10/24/2022, we were unable to provide satisfactory documentation ofan ongoing Cross Connection Contamination Prevention Program in use by our company to prevent contamination of our distribution line by Back-flow into the mainline from service lines. Although we have been assured by the distributors of the meter setter assemblies that we use to make the connection between your service lines and the main distribution line are already equipped with back-flow preventers, we have been informed that these devices are only recognized as secondary protection as they cannot be tested annually for efficacy as now required by code. This means an additional requirement forinstallation of primary backflow prevention devices on your service lines, and documentation by the company of the existence of those devices on YOUR SIDE of THE METER. When connections to our system are properly installed and maintained, the concerns are very minimal. However, unapproved, andamateur piping changes or connections such as dishwasher, clothes washer, or water softener drain lines without the required air gaps can adversely affect the quality, of the water. This not only compromises the water quality but can also affect your health. The most common potential hazard we see is a section of garden hose dangling into the surface of a stock watering trough, or pet water container.A change in pressure in the mainline (which we know can happen when there is a large demand on the system) or a simple change in air temperature or can potentially cause contaminated water to siphon back through the service line contaminating the whole system. Simple back-flow preventers like this atmospheric vacuum breaker on the hose bib, the appliance, or stock tank in-flowcan prevent this. Additionally, air gaps between the surface of standing water and the service line are easy to provide. If you see a watering trough inlet hose contacting with the standing water in the trough, take the time to wire it back up to where it is not contacting the standing water. Do not make or allow improper connections at your homes. Even that unprotected garden hose lying in the puddle next to a driveway is across connection. The unprotected lawn sprinkler system after you have fertilized or sprayed is also a cross connection. When a cross connection can exist at your home it will affect you and your family first.

It consists of chlorine tablets in a PVC tube, with holes in the tube, which is then lowered into storage tank facility ST001. This PVC tube is inside the storage tank on a continuous basis.” Since that time the company has made ongoing efforts to install a chlorination system that meets the requirements set forth. Due to supply chain issues, availability of labor, and weather conditions on the site there have been delays, but the system was finally completed and operational on 6/24/2024. Bacteriological test Results (North Well) –During 2023 and the first part of 2024, we have had several failed bacteriological samples for Coliform contamination. After each failed result, the north well was taken off-line and the system was shocked with a heavy concentration of Calcium Hypochlorite and left to rest for 24 hours. The system was then flushed before putting the well back on-line. At the end of June 2024, the pump in the North Well stopped functioning. While replacing the pump in the well, there were several holes discovered in the water pipe. These holes were causing a severe loss of pressure and was potentially causing the failed test results for Coliform contamination. The pipes with the holes have been replaced and the new pump is working properly. Hopefully this will resolve the issues we were having. EGC Pipeline routinely monitors constituents in our drinking water in accordance with the Federal and Utah State laws, however from time to time, mistakes are made. Tests that should have been made to monitor Coliform Bacteria on the distribution system was missed nitrates in our water sources for the summer of 2022 were not made. The following tables show the results of our monitoring for the period of January 1st2019to December 31st, 2022. Source of Drinking Water The drinking water for our system originates principally from Buckskin Spring and is supplemented by a well on the North end of the gravity flow system. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include: Microbial contaminants, such as viruses and bacteria which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming. Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses. Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems. Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPAs Safe Drinking Water Hotline at (800) 426-4791. In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health. Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800) 426-4791. If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. We cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead. Going forward, as work continues, the mandated change in methods of disinfection of our culinary water delivery system and scheduled repairs and changes to the mainline are made, company management will be more vigilant in monitoring the timing of disruptions to the system pressure in hopes another incident may be averted. As indicated in the final paragraph of p. 1 of this report, a change in written policy addressing backflow prevention devices on the shareholder side of the meter is also deemed necessary as company by-laws protecting the best interest of the company allow. CONSTITUENT TABLE DEFINITIONS In the following table you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms we've provided the following definitions: Non-Detects (ND)- Laboratory analysis indicates that the constituent is not present. ND/Low - High - For water systems that have multiple sources of water, the Utah Division of Drinking Water has given water systems the option of listing the test results of the constituents in one table, instead of multiple tables. To accomplish this, the lowest and highest values detected in the multiple sources are recorded in the same space in the report table. Parts per million (ppm) or Milligrams per liter (mg/l)- One part per million corresponds to one minute in two years or a single penny in $10,000. Parts per billion (ppb) or Micrograms per liter (ug/l) - One part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000. Parts per trillion (ppt) or Nanograms per liter (nanograms/l)- One part per trillion corresponds to one minute in 2,000,000 years, or a single penny in $10,000,000,000. Parts per quadrillion (ppq) or Picograms per liter (picograms/l)- One part per quadrillion corresponds to one minute in 2,000,000,000 years or one penny in $10,000,000,000,000. Picocuries per liter (pCi/L)- Picocuries per liter is a measure of the radioactivity in water. Millirems per year (mrem/yr)- Measure of radiation absorbed by the body. Million Fibers per Liter (MFL)- Million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10 micrometers. Nephelometric Turbidity Unit (NTU)- Nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person. Action Level (AL)- The concentration of a contaminant which, if exceeded, triggers treatment or other Maximum Contaminant Level (MCL)- The “Maximum Allowed” (MCL) is the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. Maximum Contaminant Level Goal (MCLG)- The “Goal”(MCLG) is the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. Date - Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years, sampling dates may seem out-dated. Waivers (W)-Because some chemicals are not used or stored in areas around drinking water sources, some water systems have been given waivers that exempt them from having to take certain chemical samples, these waivers are also tied to Drinking Water Source Protection Plans.
