3 DRINKING WATER SUPPLY CONTINGENCY PLAN Copies of this plan are in the following locations: 1. Malta Village Town Hall 2. Malta Village Pump House 3. Malta Village Water Treatment Plant The following person(s) are thoroughly familiar with the emergency plan and are authorized to implement all or part of the plan as necessary: Name Address Phone During If no answer call Office Hours Darrin Carpenter, P.O. Box 000, Malta, Village Administrator XX Damon Drake, Water Operator P.O. Box 000, Malta, XX Cell Paul Barkhurst, Mayor P.O. Box 000, Malta, XX Cell Note: Contingency plans must be updated at least yearly and a copy of the reviewed plan submitted to the: State EPA, District Office This contingency plan was revised on: 12/18/06 by Damon Drake 3

4 Power Outage 1. Contact power-company using the phone number for the company found in Appendix A. Get an estimate on the time till power is restored. 2. If the time estimate for power restoration is such that depressurization may occur, then do the following: a. Contact critical water users in Appendix B. b. Contact emergency personnel and agencies to notify them of the situation (i.e. fire dept., EMS, State EPA, etc.) found in Appendix A. c. Notify Public in the affected area with water advisory found in Appendix H. d. If depressurization will occur, follow depressurization policy found in Appendix E. e. If facilities are available, use emergency power generating equipment to restore power. The procedure for implementing emergency power is as follows: Backup generators at the Water Treatment Plan will automatically start up and run the wells and treatment plant. 4

5 Water Break 1. Evaluate if the break can be repaired under pressure, if it cannot, and depressurization will or has occurred, do the following: a. Contact critical users in Appendix B as necessary. b. Contact emergency personnel and agencies to notify them of the situation (i.e. fire dept., EMS, State EPA, etc.) found in Appendix A. c. Notify Public in the affected area with water advisory found in Appendix H. d. Follow depressurization policy found in Appendix E. (Note: It is preferable to repair a water break under pressure, if at all possible to reduce the likelihood of contamination) 2. Contact work personnel, City Officials, and Contractors as necessary in order to proceed repairing the break found in Appendix A. 3. If valves must be shut off to isolate the area of the break, isolate as small an area as possible. 4. Make an inventory of the parts necessary to repair the break. Obtain the parts as necessary using the Supplier and Parts list found in Appendix I. 5

6 SOURCE FAILURE AND CHLORINATION FAILURE In the event of the failure of any well of the for any reason, said well shall be shut in and removed from the Village water system. Said well shall be immediately cleaned and repaired and during the cleaning and repairing efforts, supplies shall be furnished to the Village from the remaining wells. In the event that the remaining wells do not furnish sufficient water to supply the Village water system, then water will be drawn through the river crossing line already established with McConnelsville for that purpose. In the event of a loss of the Village water supply to the well field, immediate steps shall be taken to draw water through the river crossing line from McConnelsville as previously described, until new wells can be drilled and proper service restored. In the event that sufficient water is not available to furnish the water supply system of the Village, water hours shall be established by the Village Administrator to allow the use of the Village water system on certain specified times as delineated by him in consideration of the circumstances of the emergency. The Village Administrator is also empowered to haul emergency water supplies from any convenient point during the time of the well field loss. The Village chlorine system is located at the Water Treatment Plant at 2620 Poplar Ridge Road. Our system is presently set up with two Regal Direct Cylinder mounted gas chlorinators using 150 lb. Cylinders on an automatic switchover system. There are two booster pumps used in this system on an alternating basis. If there is a booster pump failure an alarm will be called out to the designated personnel and the other pump will go on line. In the event that both pumps fail we have approximately 580,000 gallons of treated water in water storage tower #1 and # 2. This should give us the necessary time to make the necessary repairs. Should a power failure occur the chlorine system will also be run by backup generators. DISTRIBUTION SYSTEM STORAGE FAILURE In the event of water system storage failure, the local fire department will be notified in case of fire. Malta Village has two storage tanks (No. 1 and No. 2). If No. 1 storage tank fails the tank will be bypassed and water pumped to no. 2 tank with manual operation of elevation control. If no. 2 tank fails the system will work off of no. 1 tank in the automatic mode with no. 2 tank shut out of the system. In the event that both tanks fail, pressure relief valves will be located on fire hydrants at the farthest ends of the water system which are Andrew Trombley s property and Front Street at the southern corporation limit. The pumps will run continually and pressure will be relieved through the relief valves until the problem is repaired. We also at the present time can use the emergency connection with the Village of McConnelsville for a supply of water, supply bottled water or haul water from Stockport Village 6

7 INORGANIC/ORGANIC CONTAMINATION In the event that the Village water system is contaminated by chemicals or other hazardous substances, the Village water system shall be immediately shut down, drained, cleaned, sterilized and refilled prior to its being reopened for use. BACTERIAL CONTAMINATION In the event that the Village Water system is contaminated with bacteria, the cause of the contamination shall be immediately isolated and repairs shall be immediately effected to stop any future contamination. If the Village Water system is found to contain bacterial contamination, immediate steps shall be taken to increase the level of chlorination by either increasing chlorination to the water system or manually chlorinating the water system until bacterial residue is removed from the water supply. In cases of extreme bacterial water contamination, the Village water system shall be shut off, drained and refilled with noncontaminated supplies. Prior to the refilling of the system, the system shall be sterilized by being flushed with clean water with a chlorine residual of not less that 1.5 parts per million. This sterilization shall proceed for a period of two hours, prior to the refilling of the system or until the furthermost point of water distribution shows no bacteria in any water sample taken from it. WATER SYSTEM DEPRESSURIZATION In the event that the water system of the is depressurized, the system shall be returned to normal by turning water into the mains in a progressive system originating at the reservoir and terminating at the furthermost distribution point. Prior to the return of the system to normal service, steps will be taken to sterilize the water system and to insure that all rust, mud and other particulate are removed from the Village water mains and branch lines. SEE APPENDIX E FOR MORE DETAILS. SUSPECTED BACKFLOW OR CROSS CONNECTION In the event of suspected backflow or cross connection, the Village water department will shut off pumps and try to locate and isolate the problem area and shut it out of the system with a series of valves. The area of contamination will be flushed and tested until there isn't any contamination in the water system. in the meantime another crew or agency will be sending out notification to the public that there is a problem with the water supply, and that it shouldn't be consumed until further notice. The Village Administrator will then see that the problem area is corrected or eliminated to safeguard against future problems. 7

8 TRANSFER PUMP FAILURE In the event that a transfer pump shall fail, immediate repair shall be made to said pump by the. Should said pump not be capable of being repaired, the system shall be operated on the other pumps in place until the repair of the pump can be made. FIRE AND/OR NATURAL DISASTER In the event of a fire or other natural disaster to the Village wells, immediate replacement shall be made of the portions of the water system damaged or destroyed by fire or disaster. The Village Administrator shall be authorized to procure said parts as are necessary to effectuate said repair. If the Village water system is completely shut down by fire or disaster, water will be drawn from McConnelsville Village through the river crossing line as prescribed for emergencies, or bottled water will be supplied or water will be hauled from Stockport Village. VANDALISM OR TERRORISM In the event of vandalism to any portion of the Village water system, it shall be immediately repaired by the Village Administrator. If repairs cannot be immediately made, water will be drawn from McConnelsville Village through the river crossing line, bottled water will be supplied or water will be hauled from Stockport Village. DROUGHT RESPONSE A. In drought conditions when a decrease in ground water levels occur that will result in reduction of well production; the authorized legal representative of the Malta Utility Division shall declare an emergency that conservation of the water supply is necessary. Water use restrictions shall be imposed as the situation demands. B. Consumers shall be notified of water use restrictions by advertising in a local news media or other media known to reach a majority of Malta water users. C. Ordinance # 289, which became effective December 3, 1970 and titled "Malta Division Rules and Regulations ", Section 6, authorizes the enforcement of water use restrictions. D. Available alternate sources of supply shall be the same as in the paragraph "Source failure and chlorination failure". In the event of the absence of the Village Administrator during any emergency to the Village Water system, action required to be taken by him under the provisions of this section shall be taken first, by the Mayor, second, by the President of Council, 8

9 and third, by members of Council in order or their severity.

11 Appendix C C Section 10: Disinfection Procedures When Cutting Into Or Repairing Existing Mains The following procedures apply primarily when existing mains are wholly or partially dewatered. After the appropriate procedures have been completed, the existing main may be returned to service prior to completion of bacteriological testing in order to minimize the time customers are out of water. Leaks or breaks that are repaired with clamping devices while the mains remain full of pressurized water represent little danger of contamination and require no disinfection. Sec Trench Treatment When an existing main is opened, either by accident or by design, the excavation will likely be wet and may be badly decontaminated from nearby sewers. Liberal quantities of hypochlorite applied to open trench areas will lessen the danger from such pollution. Tablets have the advantage in such a situation because they dissolve slowly and continue to release hypochlorite as water is pumped from the excavation. Sec Swabbing With Hypochlorite Solution The interior of all pipe fittings (particularly couplings and sleeves) used in making the repair shall be swabbed or sprayed with a 1 percent hypochlorite solution before they are installed. Sec Flushing Thorough flushing is the most practical means of removing contamination introduced during repairs. If valve and hydrant locations permit flushing toward the work location from both directions is recommended. Flushing shall be started as soon as the repairs are completed and shall be continued until discolored water is eliminated. Sec Slug Chlorination When practical, in addition to the procedures above, the section of the main in which the break is located shall be isolated, all service connections shall be shut off, and the section flushed and chlorinated as described in Sec. 5.3, except that the dose may be increased to as much as 300 mg/l and the contact time reduced to as little as 15 min. After chlorination, flushing shall be resumed and continued until discolored water is eliminated, and the water has a noticeable chlorine odor. Sec Sampling Bacteriological samples shall be taken after the repairs are completed to provide a record for determining the procedure s effectiveness. If the direction of the flow is unknown, then the samples shall be taken on each side of the water main. If positive bacteriological samples are recorded, then the situation shall be evaluated by the purchaser (or purchaser s representative) who can determine corrective action, and daily sampling shall be continued until two consecutive negative samples are recorded. 11

12 Appendix D Total Coliform Positive Sample Procedure (Procedure to follow when a routine coliform positive result occurs.) Should any routine sample result be determined as total coliform positive, then a public water system must do the following: 1. Take four repeat samples within 24 hours of being notified of the routine positive sample result. These repeat samples must be collected from the following locations: a. At the routine sampling location. b. One within five service connections upstream of the routine sample site. c. One within five service connections downstream of the routine sample site. d. One within five service connections upstream or downstream of the routine sample site. e. Contact the District State EPA Office as soon as possible Should an acute violation of the Maximum Contaminant Level for Total Coliform occur, the public water system must do the following: a. Contact the State EPA, District Office immediately at and forward a copy of the analyses to the State EPA, District Office within 24 hours; b. Issue the required public notice and water use/boil advisory in the affected area; c. Notify critical users immediately (a listing of critical users can be found in the for the water system). d. Immediately conduct an investigation to determine and eliminate the source of contamination; e. Continue sampling and keep the boil advisory in effect until at least two consecutive sets of repeat bacteriological samples, taken 24 ours apart, are determined as Total Coliform negative. (Each set of samples most consists of at least four samples.) 12

13 Appendix E Depressurization Policy Depressurization Situations Cause A: Water Treatment Plant shut down, pump station shut down, power outages, storage tank failures, major fire events which drain the water system. Action: 1. Water must be considered Total Coliform Positive. 2. Consumers impacted by the depressurization must be advised to boil their water until the water is proven to be total coliform negative. 3. To be determined if the system is safe single samples must be taken at locations which are representative of the distribution system which has been impacted. If the samples are determined to be Total Coliform negative, the boil advisory can be lifted. If samples are determined as Total Coliform Positive, follow procedure in Appendix D. Cause B: Water line breaks, scheduled maintenance for other physical disruptions to the water system. Action: 1. If the water line break is repaired under pressure, than the integrity for the system is assumed to have been maintained and no bacteriological testing will be required. 2. If depressurization occurs, then the water system shall be considered Total Coliform positive and the procedure listed in Cause A must be followed. Exceptions: If the following conditions are met, the water system will not have to issue a boil advisory. 1. There is a historical record of adequate chlorine residual in the general area affected covering at least 12 monthly readings. 2. Samples for bacteriological examinations are taken in the affected area immediately and approximately 12 hours later. 3. Test for residual chlorine taken at not more than hourly intervals in the affected area for several hours do not vary significantly from the historical record. If significant decrease in chlorine residual occurs, at boil order shall be issues. 4. A visual observation of turbidity by a qualified person indicates an acceptable turbidity level. 13

14 Appendix F STATE EPA Laboratory Instructions For the Collection of Drinking Water Samples For Total Coliform Analyses The prescribed procedures must be followed in detail for a valid laboratory analysis. 1. Select the sampling tap a. A tap, such as faucet, or small valve, is preferable. Do not sample from hoses or drinking water fountains. b. Avoid taps with a leak at the stem or taps with a swivel joint. c. Aerated or screened nozzles may harbor bacteria. The aerator or screen must be removed before collection of the sample. d. Place all carbon filters, sediment filters and water softeners on bypass unless operated by a public water system. e. Sanitize the nozzle of the tap with a chlorine solution. i. Use a 5.25% sodium hypochlorite solution, such as Chlorox TM liquid bleach. Do not use chlorine solutions with special scents. To prepare a sanitizing solution that will contain about 400 mg/l of available chlorine (as hypochlorite) from the 5.25% sodium hypochlorite, add one ounce of bleach to one gallon of water (or 1 tablespoon per half-gallon). Store the mixed solution in a tightly closed screw capped container. The solution should be discarded and remade six months after preparation. Stronger solutions can be used, however, some faucet discoloration may result. ii. iii. Flush the sample tap to waste for one minute. Close the valve. Apply the sanitizing solution, prepared in step (i) above to the nozzle. This can be accomplished by either using a spray bottle or a plastic bag. (1) Using a spray bottle, saturate the tap opening with sanitizing solution then wait at least two minutes before proceeding or (2) Place a bag over the nozzle and hold the top of the bag tightly on the tap. Alternately squeeze and release the bag to flush the solution in and out of the tap. Do this for two minutes. A fresh solution and bag must be used to sanitize each tap. 2. Flush the tap The sample to be collected is intended to be representative of the water in the main. The tap must be opened fully and the water run to waste for at least 3-5 minutes to allow for adequate flushing of the piping between the tap and water main. 3. Reduce the flow from the tap 14

15 This will allow the sample bottle to be filled without splashing. 4. Remove the cap from the sample bottle a. Grasp the bottom of the sample bottle. b. Remove the cap and hold the exterior of the cap between fingers while filling the sample bottle. Take care not to touch the mouth of the bottle or the inside of the cap with fingers or the sample could become contaminated. c. The bottle must be open only during the collection of the sample. 5. Fill the sample bottle a. Do not rinse out the bottle before collecting the sample. Do not remove any 'pills' from the bottle. The bottle contains a small amount of sodium thiosulfate to neutralize the chlorine in the water. b. Do not touch the rim or mouth of the bottle during collection of the sample. c. Do not overflow. Fill the bottle to within 1/2-1" of the top. 6. Immediately recap the sample bottle tightly If there is any question as to whether a sample or bottle has become contaminated during collection of the sample, the sample must be discarded and a new sample collected in a new sample bottle. 7. Deliver the sample to the laboratory as soon as possible The laboratory must receive the sample so that analysis can be initiated within 30 hours after collection. Allow the laboratory adequate time to analyze the sample. Certified laboratories will not test samples greater than 30 hours old because the results will be invalid and the laboratory risks loss of certification. 15

16 Appendix G Example Boil Advisory Public Notice Acute Bacteriological Violation Public water systems are required by Rule , of the State Administrative Code (OAC) to routinely monitor the bacterial quality of the drinking water in their distribution system. The sampling conducted for the water system indicated that the permissible maximum contaminant levels for Total Coliform as specified in rule of the OAC was exceeded in out of the samples collected in. The United States Environmental Protection Agency (USEPA) sets drinking water standards and has determined that the presence of coliform bacteria is a serious health concern. These bacteria are generally not harmful themselves, but their presence in drinking water is serious because they often are associated with sewage or animal wastes. The presence of these bacteria in drinking water is generally a result of a problem with water treatment or the pipes, which distribute the water, and indicates that the water may be contaminated with organisms that can cause disease. Disease symptoms may include diarrhea, cramps, fever, nausea, and possibly jaundice, and any associated headaches and fatigue. These symptoms, however are not just associated with disease-causing organisms in drinking water, but also may be caused by a number of factors other than your drinking water. USEPA has set an enforceable drinking water standard for coliform bacteria to reduce the risk of adverse health effects. Under this standard, drinking water samples must be free of coliform bacteria. Drinking water which is free of coliform bacteria is usually not associated with a health risk from disease-causing bacteria and should be considered safe. State and local health authorities recommend tat consumers take the following precautions: Until further notice, consumer s vigorously boil, for at least one minute, any water used for drinking (including water used to make ice), cooking or oral hygiene. The water department/management is conducting an investigation and collecting additional samples and hopes to have this problem corrected soon. An additional notice will be given then the water use advisory is lifted. For further information contact John Doe at * The paragraph in quotation marks is mandatory wording. 16

17 Appendix H Example Boil Advisory-Precautionary Due to (describe the problem, for example: a major break): The is advising all residents in the following area, that until further notice, all consumers vigorously boil for at least one minute, any water used for drinking (including water used to make ice), cooking or oral hygiene. (Use only if appropriate) The has no evidence at this time that the water system is contaminated. The possibility does exist, however that the water system is contaminated and is issuing this advisory as a precaution. The water department is conducting an investigation and collecting samples and hopes to have this problem corrected soon. An additional notice will be given when the water use advisory is lifted.
