Section 4. Events that Cause Emergencies

The events listed below may cause water system emergencies. They are arranged from highest to lowest probable risk.

Events that cause emergencies

Type of event Probability or risk (High-Med-Low)

Comments

Earthquake

High Had minor earthquake damages in February 2001. Downtown water tower needs to be seismically retrofitted. Although it has been drained since 2001 and is not connected to the system, the tower is adjacent to the SE Thurston County Emergency Operations Center and well heads and would present a hazard in a significant earthquake.

Flood

Low City has experienced little urban flooding since improving drainage system after 1996 event. Overflow of Canal could impact homes, Nisqually River level could require closure of McKenna bridge impacting traffic flows.

Volcanic Event

Low A Lahar event could impact the Yelm area outside the city limits. Impact to traffic flows in and out of the City would be significant.

Wildland Fire

Med Prairie setting is vulnerable to fires, although few incidents have occured.

Landslide

Low Prairie setting results in little probability of event occurring.

Terrorism

Low Yelm has completed a Security Vulnerability Self-Assessment

Construction accident

Med Construction crews may hit buried waterlines.

Chemical spill

Low Addressed in wellhead protection plan.

Wellhead contamination

Med Both supply wells are located in the same aquifer, capture zone, and wellhead protection area. A contamination risk to one well would likely impact both wells.


Wind storm High System is vulnerable to high wind events, power may be disrupted.


Section 5. Severity of Emergencies

Decisions on severity should be collaborative among system personnel, but are ultimately made by the person in charge of the emergency. The information for making such a decision will accumulate over time, and may result in changes in the assessment of severity.

Communicate each assessment of severity immediately to all those dealing with the emergency. Make sure staff have cell phones, pagers, or radios when they are in the field.

Level I – Normal (Routine) Emergency: The system experiences a normal emergency, such as a line break or power outage. System personnel are able to handle the problem with minimal outside assistance. In this situation it is not likely that public health will be immediately jeopardized. Although it is important to begin responding, system personnel should have no difficulty remaining calm and thoroughly working through the situation. Normal events can usually be resolved within 24 hours.

Description: The City of Yelm water system considers the following as Level I Emergencies:

1. Distribution line breaks.

2. Inoperable or broken water valves.

3. Broken fire hydrants.

4. Short power outages.

5. Minor mechanical problems in pump-houses.

6. A minor act of vandalism.

7. Other minor situations where it is not likely that public health will be jeopardized.

The system has specific response activities identified for these types of emergencies, including proper sampling, disinfection, and pressure testing activities. System personnel are advised and are directed to work on the problem and are usually capable of resolving the problem within 24 hours. If it is determined that the problem will take longer than 24 hours to resolve and storage is likely to be drawn down below a safe operating level, the situation will be elevated to Level II.

Level II – Minor Emergency (Alert Status): The system experiences minor disruption in supply or has indications of possible contamination where it may need to coordinate with DOH and consider issuing a health advisory to customers. In these types of emergencies, public health may be jeopardized, so it is important for system personnel to be on alert and initiate a quick response. Minor emergencies can usually be resolved within 72 hours.

Description: The City of Yelm water system considers the following to be Level II Emergencies:

1. Disruption in supply such as a transmission main line break, pump failure with a potential for backflow, and loss of pressure.

2. Storage is not adequate to handle disruption in supply.


3. An initial primary chemical contaminant sample.

4. A disruption in chlorine/chemical feed from the groundwater sources.

5. Drought, with a noticeable and continuing decline of water level in the wells.

Level III – Significant Emergency: The system experiences significant mechanical or contamination problems where disruption in supply is inevitable and issuance of a health advisory is needed to protect public health. Major emergencies should be reported to DOH as soon as possible to determine the best available means to protect customers’ health. System personnel are directed to the situation, and outside entities are notified to aid in the response. Major emergencies may require more than 72 hours to resolve.

Description: The City of Yelm water system considers the following as Level III or actual emergencies:

1. A verified acute confirmed coliform MCL or E. coli/fecal positive sample requiring immediate consideration of a healthy advisory notice to customers.

2. A confirmed sample of another primary contaminant requiring immediate consideration of a health advisory notice to customers.

3. A loss or complete malfunction of the chlorination system for the groundwater source.

4. A major line break or other system failure resulting in a water shortage or requiring system shutdown.

5. An act of vandalism or terrorist threat such as intrusion or damage to a primary facility.

6. An immediate threat to public health of the customers and an advisory is required.

7. Severe drought significantly affecting well yield.

8. Bypass valve at Wells 1A and 2 open during a period of low system pressure in an emergency, creating limited chlorine contact time.

Level IV – Catastrophic Disaster/Major Emergency: The system experiences major damage or contamination from a natural disaster, an accident, or an act of terrorism. These incidents usually require immediate notification of local law enforcement and local emergency management services. Immediate issuance of health advisories and declaration of water supply emergencies are critical to protect public health. These events often take several days or weeks to resolve before the system returns to normal operation.

Description: The City of Yelm water system considers the following events to be Level IV or major emergencies:

1. Earthquake that shuts down the system or impacts sources, lines, etc.

2. Act of terrorism possibly contaminating the water system with biological or chemical agents.

3. Flood that infiltrates system facilities and sources.

4. Chemical spill within 2000 feet of the system’s sources.


5. Storm that significantly damages power grid and system facilities.

6. Mudslide or other earth shift that causes failure of transmission or loss of water in well.

7. Catastrophic failure of an existing reservoir.

Key messages

Develop possible messages in advance, and update them as the emergency develops:

• We are taking this incident seriously and doing everything we can to resolve it.

• Our primary concern is protecting our customers’ health.

• Another important concern is keeping the system operational and preventing damage.

• What we know right now is ____________________

• The information we have is incomplete. We will keep you informed as soon as we know more.

• We have contacted state and local officials to help us respond effectively.

• If you think you may be ill or need medical advice, contact a physician.

• We are sampling the water and doing tests to determine whether there is contamination.

• When the situation is resolved we will notify our customers.


Health advisories

During events when water quality and human health are in question, it may be necessary to issue a health advisory that gives advice or recommendations to water system customers on how to protect their health when drinking water is considered unsafe. These advisories are issued when the health risks to the consumers are sufficient, in the estimation of the water system or state or local health officials, to warrant such advice.

Health advisories usually take the form of a drinking water warning or boil water advisory. Communication during these times is critical. Health advisories should always be well thought out and provide very clear messages.

The Division of Drinking Water has put together a number of tools, including fact sheets, brochures, forms, and templates to help prepare for a health advisory. These are on the Web at: http://www.doh.wa.gov/ehp/dw


Section 9. The Vulnerability Assessment

This is an evaluation of each water system component to identify weaknesses or deficiencies that may make them susceptible to damage or failure during an emergency. It also assesses facilities for security enhancements that may guard against unauthorized entry, vandalism, or terrorism.

Facility vulnerability assessment and improvements identification

System component

Description and condition

Vulnerability Improvements or mitigating actions

Security improvements

Source

Two groundwater wells supply the system (Well 1A is 69 feet and Well 2 is 61 feet deep). They are located in the town center near commercial and residential areas. The sources are in good condition.

The wells are most vulnerable to contamination from above ground activities because they are relatively shallow. The well houses are not highly secure and could be vulnerable to acts of vandalism.

Update wellhead protection program. Although inactive, Well 3A could be physically connected to the distribution system. Back-up generator has been installed to run wells in event of power outage. In the event of an emergency which renders Wells 1A and 2 incapable of supplying water, Well 3A could be utilized as an emergency source.

Upgrade well houses: Install fencing, and deadbolts. Secure well houses to foundation and install lighting around well house.

Storage

Two storage reservoirs are in use. The Baker Hill tank (constructed in 1976) and the Public Works tank (constructed in 2005) each provide 500,000 gallons of storage at a maximum elevation of 477 feet. The tanks are in sound condition.

Vandals could access reservoir hatches. Also, the reservoir could be prone to shaking and settling resulting from an earthquake.

The Baker Hill tank and Public Works tanks have earthquake strapping to secure reservoirs to the foundation. The downtown tower is in need of additional reinforcement to protect from earthquake damage, but is currently empty.

Install fencing, lighting, and signage to protect against unauthorized entry and access to reservoir hatches.

Treatment

Chlorine gas is used for disinfection in the dedicated transmission main from the wells to the reservoir. The pH adjustment system includes a 2,000-gallon polyethylene caustic soda tank and direct injection into the transmission main.

Chlorine gas is a hazard and could be subject to vandalism if a pump-house is vandalized. Tanks are secured to the wall.

Verify tanks are secured with earthquake straps and protected from vandalism.

Periodically inspect fencing, lighting, and signage to protect against unauthorized entry.

Computer and telemetry system

Computer and telemetry systems are located in the Public Works Shop and at the pumphouse. All systems are in good operating condition.

Public Works Shop is adequately secured to protect equipment from cyber attack or hacking.

Install lighting and security system to guard against theft and vandalism. Also, computers should be routinely updated with security programming.

Section 11. Alternative Water Sources

Intertie to adjacent water supply system

Water systems within one-quarter mile of our system

Feasibility of connecting

Nisqually Pines is within a quarter mile of the City of Yelm system

No intertie plan has been developed. Nisqually Pines sources have a capacity of 2,110 gpm (from DOH Office of Drinking Water records). It is unlikely that an interconnection would be beneficial.

Alternate source(s) of water

Yelm is in the process of developing a new well in southwest Yelm which will result in a new source being located 1.5 miles from the two existing wells. Completion of the source is scheduled for 2011. This will greatly enhance the City’s ability to respond to an emergency water shortage due to contamination or spill at the existing well site. In the interim period, the most feasible source of water in case of emergency would be the City of Yelm Well 3A which was taken out of service when it was determined to be under the influence of surface water. Well 3A could be used as a temporary source of water in case of emergency. In order to bring this well on line to serve the system, the following steps would need to be taken:

1. Replace pipe that has been removed

2. Begin pumping

3. Test equipment and water quality

Alternate sources of water in the area are smaller systems that would not likely provide a substantial amount of water to the City of Yelm. The improvements required to construct an interconnect from these systems are significant, and would not yield a large supply of water in an emergency. These sources have been considered for long term options in the Contingency Plan, and are included for reference below. Other options for Emergency Response would include hauling water from Fort Lewis, seeking assistance from the National Guard, Red Cross, or other emergency response organization.
