Appendix B: Operations Emergency Action Plan Operations Emergency Action Plan — plan modified for Kona Well Emergency on 20170810 Emergency occurs — share news & updates with who? Internal & Immediate (after hours and weekends — 76% of every week): • Electricians �, Electrician Supervisor — only if help required • Operations Management — Baseyard S Hilo—.= (Electrician) determination if to involve ME If no water areas, and many trouble calls keeping staff from fixing problem, District Supervisor has discretion on assigning additional staff to answer emergency calls. During large emergencies Hilo Baseyard staff may be on-call or called in to assist. • Administration — Manager— or Deputy— and their discretion for PR Internal & normal office hours: Engineer Division . Can call= if he needs to pull plans for planning purposes. Finance Division & Customer Service continue to keep customer service staff informed of possible outage and extend of issue. Administration will follow triage flow chart on who to inform (Handout: "Event: Loss of Additional Source") What: Back-up water source: • Water buffalo — from baseyards. 3 small (400 gallon) tanks on trailers are stored with safe and sampled water and these can be mobilized and placed into service quickly. "Baseyard staff authorized to haul & operate" list would need to be generated and maintained. Drive -time from other districts would need to be factored in prior to mobilization. These are typically not mobilized, but have fresh water replaced and are sampled every 2 weeks. • ACR Contract hauler. Will take at least 2 hours from Hilo to Kona, plus time for driver to modify schedule and pack for 12 hour shift. First tanker load will need to be filled in Hilo @ baseyard and sampled by micro -lab for pathogen test. This may involve Microlab staff being on-call for reporting to baseyard for sampling. Hilo baseyard would need to be opened and tanker filled. If second truck mobilized, also need to have that filled and sampled. Potential future wish list would be to purchase a tanker (with emergency preparedness funds) to have DWS tanker available for emergencies? • Spigots in nearby neighborhoods where water connected. Should we be tracking water consumption by installing meters on these temporary spigots? If not a lot of use, move to higher need area? Typically, these are directly connected to fire hydrant with adapters and terminate with a hose bibb. If we do not currently have units configured at each baseyard that are ready to go, configure one for every field track with backflow prevention device? Hydrant adaptor, backflow device, meter, spigot, could potentially install orifice on meter to reduce maximum flow and protect users. Note, whoever connects to hydrant should smell and taste to confirm no contamination... Also, consider purchasing or making portable signs saying "potable water station ahead" that can fit inside our sign bases. Department of Water Supply Contingency Plan Appendix B 129
