NR 121.05   Content of areawide water quality management plans.
NR 121.06   Designation of areawide water quality planning areas and agencies.
NR 121.07   Procedures for approval of areawide water quality management plans and plan revisions for designated areas of the state.

NR 121.01 NR 121.01Purpose. Under the authority of ss. 281.11, 281.12, 281.13, 281.15, 281.17 to 281.20, and 283.83, Stats., this chapter establishes regulations specifying policies, procedures, and requirements for Wisconsin's areawide water quality planning process. This process will result in the preparation throughout the state of areawide plans for managing the quality of waters of the state, ground and surface, public and private, including consideration of the relationship of water quality to land and water resources and uses. Under the above state statutory authority, the department of natural resources has the responsibility for the general supervision of this continuing water pollution control planning process. In areas of the state designated by the governor, the preparation of areawide water quality management plans is the responsibility of designated areawide water quality planning agencies. In the remaining areas of the state, the department will prepare areawide water quality management plans. The purpose of this planning process is to systematically evaluate alternative means of achieving state and federal water quality goals and related standards. This planning process integrates consideration of both the technical measures for water pollution abatement and the management arrangements necessary for implementing abatement measures. Public participation will be provided for throughout plan development.

NR 121.03(1) (1) “ Areawide water quality management plan" or areawide waste treatment management plan means a plan for managing, protecting and enhancing groundwater and surface water quality which considers the interrelationship of water quality and land and water resources on an areawide basis (hydrologic, political, or other).
NR 121.03(2) (2) “Areawide water quality management plans for designated areas" means areawide water quality management plans prepared by agencies designated by the governor in areas of the state similarly designated.
NR 121.03(3) (3) “Areawide water quality management plans for nondesignated areas" means areawide water quality management plans prepared by the department for all areas of the state not designated by the governor.
NR 121.03(4) (4) “Best management practices" as defined in s. 281.65 (2) (a), Stats., means practices, techniques or measures, identified in areawide water quality management plans, which are determined to be the most effective, practicable means of preventing or reducing pollutants generated from nonpoint sources to a level compatible with water quality goals.
NR 121.03(5) (5) “Cost-effectiveness analysis" means a systematic comparison of alternative means of meeting state water quality standards, effluent limitations or other treatment standards in order to identify the alternative which will minimize the total resources costs over the planning period. These resources costs include monetary costs and environmental as well as other non-monetary costs.
NR 121.03(6) (6) “Critical water quality conditions" means those ambient water conditions upon which the most stringent water quality effluent requirements are based.

NR 121.03(8) (8) “Designated management agency" means any agency designated in an areawide water quality management plan having responsibility for implementing specific plan recommendations. This may be done through direct activities of the designated management agency or through delegation to other agencies or units of government.
NR 121.03(9) (9) “Effluent limitation" as defined in s. 283.01 (6), Stats., means any restriction established by the department, including schedules of compliance, on quantities, rates, and concentrations of chemical, physical, biological, and other constituents which are discharged from point sources into the waters of this state.
NR 121.03(10) (10) “Point source", as defined in s. 283.01 (12), Stats., means any discernible, confined and discrete conveyance, including but not limited to any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation or vessel or other floating craft from which pollutants may be discharged either into the waters of this state or into a publicly owned treatment works. Point source shall not include diffused surface drainage or any ditch or channel which serves only to intermittently drain excess surface water from rain or melting snow and is not used as a means of conveying pollutants into waters of the state. Point source shall not include uncontrolled discharges composed entirely of storm runoff when these discharges are uncontaminated by any industrial or commercial activity, unless the particular storm runoff discharge has been identified by the department as a significant contributor of pollution.
NR 121.03(11) (11) “Priority watershed" means a watershed of manageable size, delineated in the areawide water quality management plan and selected according to the procedures specified in s. NR 121.07.
NR 121.03(12) (12) “Public participation process" means those activities developed for involving individual members of the public, local governmental officials, and interest groups in the areawide water quality management planning process. These activities may include: the dissemination of information to the public including plan documents and summaries in lay terms, outreach activities to identify interested members of the public, the actual involvement of the public in the decision-making process which leads to the preparation and implementation of an areawide water quality management plan, and response to the public on how their input was used.

There are 4 components to the total maximum daily load: point source allocation, nonpoint source allocation, reserve capacity and margin of safety.
NR 121.03(17) (17) “Waste load allocation" means the assignment of a portion of the total maximum daily load to each of the discharges to a water quality limited segment, such that the summation of these individual loadings does not exceed the total maximum daily load.
