NR 120.14(16) (16) Riparian buffers.

NR 120.14(16)(a) (a) Description. Riparian buffers are areas in which vegetation is enhanced or established to reduce or eliminate the movement of sediment, nutrients and other nonpoint source pollutants to adjacent surface water resources or groundwater recharge areas and to protect the banks of streams and lakes from erosion and to protect fish habitat. This practice shall be implemented using one or more of the standards in par. (c).

NR 120.14(16)(b) (b) Conditions.

NR 120.14(16)(b)1. 1. Cost-sharing may be provided only when the riparian buffers are used consistent with the approved priority watershed plan, priority lake plan or project grant application or approved priority watershed or lake plan.

NR 120.14(16)(b)2. 2. Cost-sharing may be provided for:

NR 120.14(16)(b)2.a. a. Permanent fencing to protect a riparian buffer.

NR 120.14(16)(b)2.b. b. Establishment or enhancement of permanent vegetative cover in a riparian buffer.

NR 120.14(16)(b)2.c. c. Mulch, fertilizer, seed, seedling trees and other necessary materials.

NR 120.14(16)(c) (c) Standards. NRCS field office technical guide technical standards are as follows:

NR 120.14(17) (17) Lake sediment treatment.

NR 120.14(17)(a) (a) Description. Lake sediment treatment is a chemical, physical or biological treatment of polluted lake sediments.

NR 120.14(17)(b) (b) Conditions.

NR 120.14(17)(b)1. 1. Cost-sharing may be provided for:

NR 120.14(17)(b)1.a. a. Design and treatment of lake sediments with chemical compounds, including, but not limited to, aluminum sulfate, sodium aluminate, ferric chloride, calcium hydroxide and calcium carbonate.

NR 120.14(17)(b)1.b. b. Treatment of lake sediments with physical or biological methods including, but not limited to, the aeration of water overlaying lake sediments and the biological manipulation of organisms which exacerbate sediment contamination of overlaying lake water.

NR 120.14(17)(b)2. 2. Cost-sharing may not be provided for the dredging of sediments.

NR 120.14(17)(b)3. 3. Water quality objectives shall be achieved through the control of polluted lake sediments.

NR 120.14(17)(b)4. 4. Significant nonpoint sources of the pollution to the lake shall be controlled prior to treatment of lake sediments.

NR 120.14(17)(b)5. 5. The department prior to implementation shall approve the engineering design and, if required will issue an appropriate permit.

NR 120.14(17)(c) (c) Standards. The design and proposed implementation of lake sediment treatments shall be approved by the department prior to implementation.
