018.01 Watershed
				Control Program
Systems receive a 0.5-log
Cryptosporidium
treatment credit for implementing a watershed control program that
				  meets the requirements of 179 NAC 25-018.
25-018.01A 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.
25-018.01B Systems must
				submit to the Department a proposed watershed control plan no later than one
				year before the applicable treatment compliance date. 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
				179 NAC
				25-018.01E item
				2.
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.
25-018.01C Systems with existing watershed
				control programs (i.e., programs in place on January 5, 2006) are eligible to
				seek this credit. Their watershed control plans must meet the criteria in 179
				NAC
				25-018.01B and
				must specify ongoing and future actions that will reduce source water
Cryptosporidium
levels.
25-018.01D If the Department does not respond
				to a system regarding approval of a watershed control plan submitted under 179
				NAC 25-018 and the system meets the other requirements of 179 NAC 25-018, 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.
25-018.01E 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 result of the watershed
				survey conducted under 179 NAC
				25-018.01E item
				2. 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 for community water systems and every five years for non-community
				water systems and submit the survey report to the Department. The survey must
				be conducted according to Department guidelines and by persons the Department
				approves.
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 the Department requires, which may be earlier than the regular
				date in 179 NAC
				25-018.01E item
				2.
3. 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.
25-018.01F 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.
