6 WATER SYSTEM EMERGENCY RESPONSE PLAN LANGDALE WATER SYSTEM 1.0 INTRODUCTION This Emergency Response Plan (ERP) has been developed to lessen the impact of emergencies which could affect the Sunshine Coast Regional District s (SCRD) water supply systems. This ERP has been prepared by Dayton & Knight Ltd. (D&K) for the SCRD s water systems to comply with the requirements of the British Columbia Drinking Water Protection Act and the local Health Authority. This plan also conforms to the B.C. Emergency Response Management System framework. 1.1 Purpose The overall purpose of this plan is to outline the basic procedures to be taken in the case of an emergency involving the source, transmission, treatment, storage or distribution components of the water systems. This Emergency Response Plan includes: Key plan of the Langdale system and list of critical system components. Types of emergencies and components at risk. Emergency contact names and phone numbers. Emergency response procedures (What to Do). Page

7 1.2 How to Use This Emergency Response Plan (ERP) a) Review this ERP with staff who are expected to implement it. Coordinate training and refresh training on a regular basis. b) In the event of an emergency scenario refer to Tab 4, Emergency Scenarios and Response Chart. This table lists various emergency scenarios, the corresponding water system components at risk and directs the user to the associated response tab (What to Do). c) Copies of this ERP should be readily available at the following locations: - Langdale Pump Station/Chlorination Building - SCRD Engineering and Operations Office - SCRD Emergency Response Centre - SCRD Works Yard - Vancouver Coastal Health (Sechelt) - SCRD Website d) Maintain and update in all copies of this ERP: - Chain of Command Tree - Emergency contact lists - Key plan - Critical components and equipment list At the Pump Station/Chlorination Building post up-to-date process schematics. The Langdale Pump Station detail drawing follows. An emergency plan is of little or no value if it contains out-dated information. Please ensure this Emergency Response Plan contains the latest updates. Page

10 1.3 Definitions a) Drinking Water Officer: The Drinking Water Officer for an area is the person appointed by the Medical Health Officer as the Drinking Water Officer, or if no appointment is made, the Medical Health Officer. b) Emergency * : Any event that may degrade the quality or quantity of potable water supplies available to serve customers. c) Emergency Officer: The person in charge to manage and provide assistance during an emergency such as fire, hazardous waste spill, earthquake or flooding (usually the local Fire Chief). d) General Manager: Means the General Manager of Infrastructure Services, or designate. e) Hazardous Chemical: Substance or material determined to be capable of posing an unreasonable risk to health, safety and property when transported. f) Leak: Unwanted release of material from a container or pipe through a small opening or gap, generally handled as a small spill. g) Lifeline Concept * : Infrastructure and facilities that provide essential services, and that are necessary for recovery (i.e., water, wastewater, transportation, power, communications, medical care and emergency services). h) Major Emergencies * : Affect large portions, or the entire, water system. Health and safety of the community and staff would be at risk. * Adapted from AWWA M19 Emergency Planning for Water Utility Management, Page

11 i) Major Spills: Defined in general literature as spills greater than 500 millilitres. In this case, proper procedures must be followed. j) Minor Emergencies * : Described as routine situations (i.e. pipe breaks) that are localized and affect few customers. No risk to health or safety of staff and consumers. k) Small Spill: Defined in general literature as spills less than or equal to 500 millilitres. In the case of extremely hazardous substances, spills less than 500 millilitres are considered large spills. This does not apply to the Langdale water system. l) Spill: Accidental or unexpected release of any material from a container. 1.4 Integration with Other Plans Drought Management Plan Emergency conditions that may trigger actions outlined in the Drought Management Plan include: 1. Drought. 2. Prolonged loss of primary water supply. 3. Prolonged loss of system storage. 4. Reduced storage due to fighting multiple fires. For Condition 1, drought is to be addressed within the Drought Management Plan. For Conditions 2, 3 and 4, the General Manager may implement Stage 3 or Stage 4 Water Use Bans (as provided in the plan), if deemed necessary. Refer to the SCRD s Drought Page

12 Management Plan for more details. Copies of the Drought Management Plan are available at the SCRD Office library Cross Connection Control Bylaw The primary objective of a Cross Connection Control Bylaw is to safeguard drinking water within the municipal water system from possible contamination and subsequent health risks created from backflow. Where potential sources of contamination pose a risk, physical separation or backflow prevention devices/assemblies are required to prevent the return of non-potable water to the potable water distribution system. Staff directly involved in administrating a Cross Control Bylaw as well as staff dealing with water quality and distribution system issues must be able to react as quickly as possible in order to isolate the source of contamination. The plan includes: communication to customers in the affected area; sampling; flushing; lab analysis; on-site inspections; and plan to isolate the area. Refer to the Cross Connection Control Bylaw and Tab 17 for more details Sunshine Coast Emergency Response and Recovery Plan (ERRP) The Emergency Response and Recovery Plan (ERRP) describes the roles and responsibilities of the departments and personnel for the entire Sunshine Coast Regional District during major emergencies or disasters. Page

13 While no plan can replace the common sense and good judgement of emergency response personnel, department directors and other decision makers, the ERRP does provide a framework to guide the SCRD s efforts to respond to and recover from major emergencies or disasters. There are guidelines and checklists included in the ERRP that reflect the requirements of the British Columbia Emergency Response Management System (BCERMS). In the event of a major emergency or disaster, the ERRP will govern. Copies of the ERRP can be found at the SCRD Office (see Bill Elsner, Emergency Program Coordinator) or on the SCRD s website as linked below: Training and Prevention Training and practice are essential for an effective emergency response. Training should be ongoing to reinforce previous training and introduce new staff to the program. As soon as training ends, people begin to forget what they have been taught. Also, staff turnovers decrease the number of trained personnel, and new problems, new techniques and changes in equipment dilute the readiness of the system to deal with emergency situations. The water system operators must take all reasonable measures necessary to ensure that preventable emergencies do not occur. These measures shall include, but not be limited to the following: a) Operation and Maintenance (O&M) personnel shall receive continuous and adequate training. Page

14 b) O&M of equipment, piping and material shall be carried out as per instructions in the manufacturer s manual, O&M manuals, and WCB and government regulations. c) The amount of chemicals stored shall not exceed the storage capacity of the facility or containment devices. d) Chemicals shall be handled and stored as per manufacturer s instructions. e) Detailed inspection of equipment, pipes, fittings, storage tanks and injection points shall be carried out regularly to identify any potential for leaks or spills. f) Develop and maintain an effective communication pathway to ensure proper response in the event of a future spill (see Chain of Command Tree on Tab 2). g) The List of Contacts in Section 4 and Appendix 1 shall be updated every 6 months or as required. h) The Emergency Officer shall be familiar with the MSD sheets of the chemical stored in the Chlorination Building. i) The Emergency Officer shall also be familiar with the surrounding area, local infrastructure and geography (watercourses, ditches, ground profile, vegetation, etc.). Training Courses Operations personnel should take courses in confined space entry, cardiopulmonary resuscitation (CPR) and first aid, and response to chlorine spills. A training program should be provided with details on the system and system operation. The SCRD s Utilities Supervisor is responsible for arranging training courses. Training Exercises Training and practice are essential for an effective emergency response. Training exercises allow personnel to practice response, recovery and evaluation. On-site training can be practised or table-top what-if scenarios can be worked through. Page

15 Training exercises are the key to a successful emergency response, as often the training exercises will point out problems or gaps in the intended emergency response plan. The SCRD s Utilities Supervisor is responsible for arranging training sessions. Page

16 WATER SYSTEM EMERGENCY RESPONSE PLAN LANGDALE WATER SYSTEM 2.0 SYSTEM COMPONENTS 2.1 How the System Works The Langdale system includes a 60 HP pump which draws water from the well located next to the ferry terminal. This pump runs until the reservoir level reaches the stop set point. When the pump shuts off, the reservoir will supply pressure for the system. Level control is achieved using a radio link from the reservoir to the pump station. Water quality from the well is excellent and the only treatment is the addition of hypochlorite while pumping into the system. Maintaining a chlorine dosage of 0.3 mg/l is generally adequate to maintain a good residual at the end of the system. 2.2 System Components The Langdale water system components include: Langdale Pump Station - houses well pump and chlorination equipment - pump station pumps to the distribution system and the wood stave reservoir - SCADA alarm system is set to call out for critical alarms such as chlorine residual 50,000 Igal Langdale Reservoir (wood stave) Page

17 - power to reservoir supplied from neighbour s property with an extension cord (with battery back-up) - ultrasonic level sensor with high and low alarms (at present these alarms will not result in a call out) PRV Station (1) located at Tideview Road. SCADA System (located at the pumphouse) - SCADA control of reservoir level - UPS for SCADA for 2 days - intrusion alarm on door and SCADA panel - in the event of a communication failure the local control will operate the pump for one hour on/one hour off, repeatedly, until communication is back Fire Hydrants (24) Major system components are shown in Photos 2-1 through Water Supply and Treatment Photo 2-1 Well, Pump Station, SCADA and Chlorination Building (12% Sodium Hypochlorite) Page

Potential modes of failure of this supply are through: Page

28 a) Contamination of the well Contamination of the well could impact the water quality in the distribution system, rendering the water unsafe for public use. Contamination can be bacteriological or chemical (see Tab 7). b) Loss of well pump Loss of the well pump. Alternate supply could temporarily be fed from Hopkin s Landing through an existing valve connection (see Tab 7). The Hopkin s Landing supply is unchlorinated (boil water advisory may be required at the discretion of the Drinking Water Officer (DWO)). Water Use Restrictions (following the Drought Management Plan) may apply at the discretion of the General Manager. Both modes of failure would result in loss of the source Langdale Storage Tank A wood stave 50,000 Igal storage tank provides Langdale with system storage. Plans are to replace this tank in Potential modes of failure are: a) Intrusion and/or contamination of the reservoir Intrusion and/or contamination of the tank could impact water quality in the distribution system, rendering the water unsafe for public use. (see Tab 8) Page

29 b) Low storage due to high water demand Low storage due to high water demand (i.e. for fighting multiple fires). Water use restrictions may be required at the discretion of the General Manager (see Drought Management Plan). c) Structural collapse Structural collapse. This would have an immediate impact on the home located directly below the reservoir (see Tab 10). Emergency responders including the Utilities Supervisor, Drinking Water Officer and Fire Chief must be notified in this event. System must be isolated from pumping into the reservoir PRV s There is one PRV in the Langdale system. There are two modes of failure for PRV s. a) Fail open If a PRV failed in an open position, excessive high pressure would occur at residences near the ocean shore (see Tab 18). b) Fail closed If a PRV failed in a closed position, water would be shut off to the consumers and infrastructures (i.e. hydrants) downstream of the PRV (see Tab 18). These modes of PRV failure could occur if, for example, a PRV was illegally accessed and tampered with. Page

30 3.3.4 SCADA System The SCADA System (local PLC) is presently set up to remotely control the reservoir level from the main SCADA controls located at the Langdale Pump Station. Data from the system can be viewed at the Water Treatment Plant. The SCADA system also sets high and low level alarm and building intrusion alarms. In the event of alarm, the system will call out to a standby operator. The initial phone call is to the SCRD answering service contractor (Eagle Answering Phone: ). 3.4 Recovery Program The steps to a successful recovery program after dealing with an emergency and getting the system back to operation are noted in Tab 21. The steps should be taken to prevent a similar situation (if avoidable) in the future. Page

54 PA#1 Name of Owner/Operator: Effective Date: LANGDALE WATER SYSTEM BOIL WATER NOTICE Laboratory tests indicate the presence of e.coli bacteria in the drinking water. If e.coli bacteria are present in drinking water supplies, this is a serious concern because disease-causing microorganisms (pathogens) may be present. These pathogens include bacteria, viruses and parasites that can cause enteric symptoms (diarrhea, cramps, nausea, vomiting or other symptoms). Boiling the water kills these organisms. People with weakened or undeveloped immune systems are most at risk [this includes: elderly people, pregnant women and their unborn, very young children (under 2), people with AIDS, cancer, diabetes or kidney disease and people being treated with immuno-suppressing medications (antibiotics, chemotherapy, etc.] Water users are advised to bring all water to a rolling boil for at least one minute and let it cool before using it or, use bottled water. Boiled or bottled water should be used for drinking, making ice, washing dishes, brushing teeth, and food preparation until further notice.

55 PA#2 LANGDALE WATER SYSTEM WATER QUALITY ADVISORY Laboratory tests indicate the presence of total coliform bacteria in the drinking water. The total coliforms may be due to inadequate disinfection treatment or distribution pipes that are in need of maintenance. Total coliform bacteria are naturally present in the environment and they are generally not harmful themselves but they indicate an increased chance that organisms causing intestinal illness may be present in the drinking water. People with undeveloped or severely weakened immune systems, infants, and elderly may be at increased risk. Due to the above concerns and as a precautionary measure, water users are advised to bring all water to a rolling boil for at least one minute and let it cool before using it or, use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, and food preparation until further notice. We will inform you when the Water Quality Advisory is removed.
