This contingency plan was revised on January 05, 2009 by John M. Heil.

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.

  1. If the time estimate for power restoration is such that depressurization may occur, then do

the following:

  1. Contact critical water users in Appendix C
  2. Contact emergency personnel and agencies to notify them of the situation (i.e. fire dept.,

EMS, Ohio EPA, etc.) found in Appendix A

  1. Notify Public in the affected area with water advisory found in Appendix H
  2. If depressurization will occur, follow depressurization policy
  3. If facilities are available, use emergency power generating equipment to restore power. The procedure for implementing emergency power is as follows:

Procedure:

1.)Start emergency generator located at Heck’s Grave Park.

2.)Throttle generator to 60 Hertz.

3.)Throw double pull disconnect to auxiliary power position.

4.)Turn well operation switch to HAND position.

5.)Operate until desired reservoir level is attained.

Water Break

  1. Evaluate if the break can be repaired under pressure, if it cannot, and depressurization will or has

occurred, do the following:

  1. Contact critical users in Appendix C as necessary
  2. Contact emergency personnel and agencies to notify them of the situation (i.e. fire dept.,

EMS, Ohio EPA, etc.) found in Appendix A

  1. Notify Public in the affected area with water advisory found in Appendix H
  2. Follow depressurization policy

(Note: It is preferable to repair a water break under pressure, if at all possible to reduce the likelihood of contamination)

  1. Contact work personnel, City Officials, and Contractors as necessary in order to proceed repairing

the break found in Appendix A

  1. If valves must be shut off to isolate the area of the break, isolate as small an area as possible.

Valve and water main locations are located in the Utilities truck and Village Hall.

  1. 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 J.

RECOMMENDED PROCEDURE FOR DEPRESSURIZATION

1. ( )In the event of depressurization due to water main breaks or other physical disruptions in the integrity of a water system, the system should be considered E. coli or fecal positive (unsafe) and the system must be sampled for total coliform bacteria.

a. ( )Contact critical water users in Appendix C and notify them of the situation and the necessity to boil their water.

b. ( )Immediately contact the Ohio EPA and any other emergency personnel or agencies that are appropriate for the situation using the phone number(s) found in Appendix A.

c. ( )Issue a water use/boil advisory for the affected area. Provide notice by radio, television, handbill, or continuous posting within 72 hours. (See Appendix H).

2. ( )Contact the work personnel, city officials, and contractors using the phone number(s) found in Appendix A needed to proceed with repairing the break.

3. ( )Institute any water conservation measures deemed necessary.

4. ( )If depressurization is the result of a break, isolate the area. Keep the isolated area as small as possible. 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 J.

5. ( )Take the necessary measures to restore pressure as soon as possible. Repairs must be made in accordance with AWWA C651-92 Section 10.

6. ( )Disinfect the system according to recommended procedures for line breaks or physical disruption of the integrity of the system.

7. ( )Sample for bacterial contamination. Obtain at least one set of samples that are total coliform negative before the boil advisory is lifted by Ohio EPA. Mark the sample SPECIAL PURPOSE. Even if the first set is negative, it is suggested that a second set of samples be taken. If a second set of samples is taken, they shall be considered part of routine sampling for monthly compliance purposes. NOTE: The initial samples are considered “special purpose” and will not count toward the routine total coliform monitoring requirement.

8. ( )If any sample in the initial set is coliform positive, the boil advisory will remain in place until two consecutive sets of samples are coliform negative.

9. ( )Submit a report of the incident to Ohio EPA’s District Office. Include a copy of the sample results and any pertinent notifications with the report.

Source Failure

1. Contact Ohio Drilling Company using the phone number for the company found in Appendix B. Get an estimate on the time until well is restored.

2. If the time estimate for well restoration is such that depressurization may occur, then do

the following:

  1. Contact critical water users in Appendix C
  2. Contact emergency personnel and agencies to notify them of the situation (i.e. fire dept.,

EMS, Ohio EPA, etc.) found in Appendix A

  1. Village to haul in potable water to fill storage tanks.
  2. Village to provide bottled water to Village residents.

When the well has been serviced and placed back into operation:

  1. Notify Public in the affected area with water advisory found in Appendix H
  2. Follow Depressurization Policy
  3. Notify Public in the affected area with water advisory found in Appendix I

Distribution System Storage Failure

The Village of Gnadenhutten has two storage tanks with the capability to isolate each tank. If an occasion would occur where one storage tank failed the Village would follow these steps.

  1. The Village would determine which storage tank has failed.
  2. Isolate that tank.
  3. Contact Emergency Repair Contractor List found in Appendix B.
  4. After repair is made to storage tank follow Depressurization Policy.
  5. Follow AWWA procedures for the disinfection of water storage tanks found in Appendix O.
  6. Issue Water Advisory for affected areas found in Appendix H. Notify Public in the affected area with water advisory found in Appendix I.

After inspection of the storage tanks and both tanks failed the Village would follow these steps:

  1. Contact Emergency Repair Contractor List found in Appendix B.
  2. The Village would distribute bottled water to residents.
  3. After repair is made to storage tank follow Depressurization Policy.
  4. Follow AWWA procedures for the disinfection of water storage tanks found in Appendix O.
  5. Issue Water Advisory for affected areas found in Appendix H.
  6. Notify Public in the affected area with water advisory found in Appendix I.

Inorganic/Organic Contamination

  1. Attempt to determine the specific chemical which has caused the contamination and its hazard

classification. There are four broad classifications of contaminations as follows:

Hazard Type

/ Description
Pollution Hazard / A condition through which an aesthetically objectionable or degrading material NOT dangerous to health may enter the public water system or a consumer’s potable water system (for example – a food grade product)
System Hazard / A condition, device, or practice posing an actual or potential threat of damage to the physical properties of the public water system or a consumer’s potable water system but will not cause an adverse health effect (for example- an inert material that may clog the water line but not cause illness if ingested)
Health Hazard / Any condition, device, or practice in a water supply system or its operation that creates, or may create a danger to the health and well being of others. (For example, a fluoride overfeed that results in a concentration greater than 10mg/L in the PWS)
Severe Hazard / Any health hazard that could reasonably be expected to result in a significant morbidity or death (For example-the contamination of a water system with a large amount of pesticide)
  • If a degree of hazard cannot be determined, assume it is a severe hazard.
  1. Attempt to gain or determine the following information:

Who made the first observation and their phone number and location?
When did it happen?
What is it? (What are its qualities-color/taste/smell-MSDS sheet available)
How much of it entered the water system?
Where did it enter the water system?
Where is it now? (is it isolated to an area or is it wide spread?) (area and population affected)
Can it be isolated?
Can depressurization and/or flushing of the affected area be done quickly and without serious consequences?
  1. If you determine the classification of the contamination to be either a health hazard or a severe

hazard do the following:

  1. issue a no-use water advisory immediately (Appendix M). (In general, a boil advisory will be adequate for chemical contamination and may only serve to concentrate the

contaminate)

  1. If it is felt that the contaminate will cause serious illness or death, can you isolate the water

supply from users? (Appendix L).

  1. If a water advisory is to be issued, contact critical water users in Appendix C and notify them of

the situation.

  1. Immediately contact the Ohio EPA and any other emergency personnel or agencies that are

appropriate for the situation found in Appendix A.

  1. If possible, determine the cause and source of the contamination-eliminate the source. (Consider

the possibility that the cause may be due to a cross connection, backflow or back siphonage).

  1. Begin flushing the distribution system to eliminate the contamination from the public water

supply.

Bacteriological Contamination

  1. If only routine sample has been determined as total coliform positive and no repeat samples have

yet been taken, follow the procedure found in Appendix E.

  1. If an “ACUTE” bacteriological violation has occurred, issue the example “BOIL ADVISORY”

and public notice found in Appendix G and do the following:

  1. Contact critical water users in Appendix C and notify them of the situation and the

necessity to boil their water.

  1. Immediately contact the Ohio EPA and any other emergency personnel or agencies that are

appropriate for the situation found in Appendix A.

  1. Divide the distribution system into sections. Begin bacteriological sampling in each

section and at the plant tap to determine the extent and cause of the contamination.

(Reference the water system’s “Bacteriological Sample Siting Plan” for good

sampling locations.)

  1. Ensure that at least a 0.2 mg/l free chlorine residual is maintained in all parts of the water

distribution system. If not, increase the chlorine dosage immediately. Consider dosing the storage

tanks as necessary to quickly increase the chlorine residual to the required level.

Absence of Operator

Ohio Revised Code 3745-7-02 Certified operators required:

(A) Responsibilities.

(1) Each person owning or operating a public water system, except as provided for in paragraph (B) or (E) of this rule, shall designate one or more operator of record to oversee the technical operation of the public water system or each water treatment plant and distribution system within the public water system. Each operator of record shall have a valid certification of a class equal to or greater than the classification of the public water system, distribution system or water treatment plant.

(a) The owner of a public water system shall notify the director of the identity of an operator of record in the event of a change in such position.

(b) Notification shall be made on a form acceptable to the director within three days of a change in an operator of record.

(C) The certified operator required by paragraphs (A) or (B) of this rule shall be an employee of the person owning or operating the public water system, treatment works, except as provided in paragraph (D)

of this rule.

(D) Owners of public water systems may enter into a contract for the services of one or more appropriately certified operators to serve as the operator of record provided that:

(1) The contract requires that the certified operator be available to respond to emergencies, and provide the services necessary to maintain the reliable operation of the system, and the contract is consistent with the

requirements of paragraphs (C) to (E) of rule 3745-7-03 of the Administrative Code and paragraphs (C) to (E) of rule 3745-7-04 of the Administrative Code; and

(2) A copy of the contract is maintained onsite at the public water system, treatment works, or sewerage system.

When the Operator of Record is unavailable to work due to injury, illness, vacation, etc the Village of Gnadenhutten will hire a Technical Supervisor to fill the position of Water Operator until the Operator of Record is able to return to work on a full time basis.

Flooding/Spills

The Village of Gnadenhutten currently has two wells in operation. Only one of the Village wells has the potential of flooding, due to a drainage canal located near the #2 well house. This well house also has the potential for spills, due the low lying area in which it is located (below railroad tracks).

In case of flooding or spills:

1. Discontinue power source to well house #2.

2. Run well #1 only until flooding has subsided

3. Once flooding has ended, or spill contained remove all contamination from well house.

4. Disinfect wells according to procedures found in AWWA Standards Appendix O.

5. Upon restarting the well pump a Bacteriological sample must be taken following the procedure listed in Appendix F.

6. Samples must be taken from both wells and tested for contamination prior to restarting.

6. Upon finding no contamination of the water source, the well will then be used for normal operation.

SUSPECTED TAMPERING AT SYSTEM FACILITIES

Tampering with may range from the simple defacement of property to the introduction of biological or chemical agents into the water supply. These actions can be divided into several general categories:

Action / Description
Vandalism / Actions that cause physical damage to property and structures, such as cutting fences to gain access to secure areas, breaking windows, and damaging or removing locks from doors or wells.
Malicious Action / Actions that, intentional or not, introduce or threaten to introduce foreign substances into a portion of the treatment or distribution system or cause damage to a portion of the public water systems infrastructure. These acts range from pranks that “go too far” (adding food coloring to a storage tank) to actions intended to cause a disruption to the public water supply or the introduction of toxic substances into the distribution system.
Terrorism / Intentional actions introduce or threaten to introduce foreign substances into a portion of the treatment or distribution system or cause damage to a portion of the public water systems infrastructure. These acts are meant to cause harm to individuals and cause unease or panic in the general public.

PROCEDURE

1. ( )Immediately take the following actions:

a. ( )Treat the area as a crime scene. Minimize disturbance of the area in order to preserve physical evidence, which can include fingerprints, tire tracks, tool marks, dropped materials, or tools. Document the observed conditions, with photographs and video if possible, taking care to note anything that is out of the ordinary.

b. ( )Contact the law enforcement agency listed in Appendix A. Work with local law enforcement personnel to determine if the tampering was the result of vandalism, a malicious action, terrorism, or had some other cause.

c. ( )Isolate the affected portion of the system.

d. ( )Immediately contact the Ohio EPA and any other emergency personnel or agencies that are appropriate for the situation using the phone number(s) found in Appendix A.

2. ( )Complete the following activities as soon as possible:

a. ( )If there is evidence of contamination, perform a physical check on the system and its structural integrity (check storage tanks for foreign objects, look for open hydrants, etc.).

b. ( )Contact the laboratories listed in Appendix K to determine if they are capable of analyzing for and identifying unknown substances.

c. ( )If it is determined that the tampering resulted in the probable introduction of chemical or biological contaminants into the storage tank, proper precautions must be taken during sampling to prevent exposure to the contaminant and/or daughter products.

d. ( )With the consent of law enforcement, begin to repair/secure all points of entry and other physical damage to structures.
