- (b) The O/O of a groundwater system that has multiple wells and is subject to triggered monitoring who wishes to have a triggered source water monitoring plan that correlates each approved sampling location to a specific well shall submit a written request to the department for approval of such a plan. Preparation of a plan shall not constitute grounds to extend the requirement to sample within 24 hours of notification of the positive result.

- (3) For an extension of time, a full explanation of why an extension is necessary and how much time is requested; and
- (4) For approval of a triggered source water monitoring plan, a demonstration of which wells are associated with which distribution system sampling sites.
- (d) The department shall respond to the request in writing. If the request is denied, the department’s response shall specify the reason(s) for the denial.
- (e) The department shall approve a request for an extension of time if the department determines that additional time is needed for reasons beyond the control of the system O/O.
- (f) The department shall approve a request for a triggered source water monitoring plan that correlates each sampling location to a specific well if the department determines that the proposed plan will result in samples that fulfill the intent of the sampling requirements.
