ALTERNATE WATER SUPPLY; CONTINGENCY STRATEGY

Subpart 1. Contingency strategy required. A wellhead protection plan must have a contingency strategy that addresses disruptions of the water supply caused by contamination or mechanical failures of the public water supply system. Subp. 2. Requirements. The contingency strategy must: A. identify the water supply replacement alternatives, including the location of the replacement supply that will be available during a disruption; B. be based on: (1) the location and capacity of individual wells and storage tanks; (2) the location, type, and capacity of the water treatment facility; (3) the location and capacity of major distribution lines; and (4) the location of key points for isolating parts of the water supply system; C. be based on water use and demand; D. prioritize water uses and demands into low, medium, and high categories; E. have: (1) the response coordinator's name, telephone number, address, and response assignments; (2) the names, addresses, telephone numbers, and response assignments of personnel for public health, water supply operations, and public relations; (3) an alternate for each of the individuals identified in subitems (1) and (2); (4) a list of services, equipment, and supplies available to respond to a disruption; (5) a list of services, equipment, and supplies not available but needed to respond to a disruption; and (6) a plan of action and time frame for obtaining the services, equipment, and supplies identified in subitem (5); F. have a procedure to: (1) identify the disruption; (2) notify response personnel; (3) identify incident direction and control; (4) identify internal communication; (5) inform the public; (6) assess the incident on a continual basis; (7) assess a contamination disruption; (8) assess a mechanical disruption; (9) provide an alternative water supply; and (10) impose water use restrictions; and G. identify ways to reduce the vulnerability of the water supply system to disruption and to improve the community's response capabilities.
