				Watershed control program. Systems receive 0.5-log
Cryptosporidium
treatment credit for implementing a watershed
				control program that meets the following requirements:
(a) Systems that intend to apply for the
				watershed control program credit must notify the Department of this intent no
				later than two years prior to the treatment compliance date applicable to the
				system in rule
				335-7-6-.20.
(b) Systems must submit to the Department a
				proposed watershed control plan no later than one year before the applicable
				treatment compliance date in rule
				335-7-6-.20. The Department must
				approve the watershed control plan for the system to receive watershed control
				program treatment credit. The watershed control plan must include the following
				elements:
1. Identification of an "area of
				influence" outside of which the likelihood of
Cryptosporidium
or fecal contamination affecting the treatment plant intake is not significant.
				This is the area to be evaluated in future watershed surveys under subparagraph
				(1)(e)2. of this rule.
2.
				Identification of both potential and actual sources of
Cryptosporidium
contamination and an assessment of the
				relative impact of these sources on the system's source water
				quality.
3. An analysis of the
				effectiveness and feasibility of control measures that could reduce
Cryptosporidium
loading from sources of contamination to the
				system's source water.
4. A
				statement of goals and specific actions the system will undertake to reduce
				source water
Cryptosporidium
levels. The plan must explain how
				the actions are expected to contribute to specific goals, identify watershed
				partners and their roles, identify resource requirements and commitments, and
				include a schedule for plan implementation with deadlines for completing
				specific actions identified in the plan.
(c) Systems with existing watershed control
				programs (i.e., programs in place before January 5, 2006, are eligible to seek
				this credit. Their watershed control plans must meet the criteria in
				subparagraph (1)(b) of this rule and must specify ongoing and future actions
				that will reduce source water
Cryptosporidium
levels.
(d) If the Department does
				not respond to a system regarding approval of a watershed control plan
				submitted under this section and the system meets the other requirements of
				this section, the watershed control program will be considered approved and
				0.5-log
Cryptosporidium
treatment credit will be awarded
				unless and until the Department subsequently withdraws such approval.
(e) Systems must complete the following
				actions to maintain the 0.5-log credit:
1.
				Submit an annual watershed control program status report to the Department. The
				annual watershed control program status report must describe the system's
				implementation of the approved plan and assess the adequacy of the plan to meet
				its goals. It must explain how the system is addressing any shortcomings in
				plan implementation, including those previously identified by the Department or
				as the results of the watershed survey conducted under subparagraph (1)(e)2. of
				this rule. It must also describe any significant changes that have occurred in
				the watershed since the last watershed sanitary survey. If a system determines
				during implementation that making a significant change to its approved
				watershed control program is necessary, the system must notify the Department
				prior to making any such changes. If any change is likely to reduce the level
				of source water protection, the system must also list in its notification the
				actions the system will take to mitigate this effect.
2. Undergo a watershed sanitary survey every
				three years and submit the survey report to the Department. The survey must be
				conducted according to Department guidelines and by persons approved by the
				Department.
a. The watershed sanitary survey
				must meet the following criteria: encompass the region identified in the
				Department-approved watershed control plan as the area of influence; assess the
				implementation of actions to reduce source water
Cryptosporidium
levels; and identify any significant new
				sources of
Cryptosporidium.
b. If the Department determines that
				significant changes may have occurred in the watershed since the previous
				watershed sanitary survey, systems must undergo another watershed sanitary
				survey by a date established by the Department, which may be earlier than the
				regular date in subparagraph (1)(e)2. of this rule.
c. The system must make the watershed control
				plan, annual status reports, and watershed sanitary survey reports available to
				the public upon request. These documents must be in a plain language style and
				include criteria by which to evaluate the success of the program in achieving
				plan goals. The Department may approve systems to withhold from the public
				portions of the annual status report, watershed control plan, and watershed
				sanitary survey based on water supply security considerations.
(f) If the Department
				determines that a system is not carrying out the approved watershed control
				plan, the Department may withdraw the watershed control program treatment
				credit.
