Section 335-7-15-.15 - Contingency Plans For A Surface Water Source

The water system shall submit to the Department for approval contingency activities for potential contaminant sources rated highly susceptible to entering the intake which may rapidly cause the raw water to be difficult to properly treat. Upon approval of their contingency plans, water systems shall implement them immediately and incorporate them into their Standard Operating Procedure (SOP). Contingency actions may include, but not be limited to the following items, individually, and in combination:

(a) Temporarily closing of the treatment plant,

(b) Obtaining raw water from another approved source,

(c) Obtaining finished water from another public water system,

(d) Developing adequate distribution storage for the expected duration of the contamination event,

(e) Using emergency containment devices to exclude contaminant sources from intakes.

(f) During periods when a treatment plant is closed due to the presence of excessive contaminants, it shall remain out of service until monitoring by the water system indicates the contaminant is no longer a threat to the treatment process or quality of finished water. The water system shall keep the Department informed of the status of its raw water quality whenever a contamination event results in the closure of a plant and shall furnish monitoring results to the Department. Treatment plants shall not be returned to service until approval has been received from the Department.
