ATCP 50.87(1) (1) Definition. In this section, “sinkhole treatment” means modifying a sinkhole, or the area around a sinkhole, to reduce erosion, prevent expansion of the hole, and reduce pollution of water resources. Modifications may include the diversion of runoff around a sinkhole, or the alteration of a sinkhole by excavation, cleanout, filter treatment, sealing, or refilling.

ATCP 50.87(2) (2) Eligible costs. A cost-share grant under s. ATCP 50.40 may reimburse any of the following costs related to sinkhole treatment:

ATCP 50.87(2)(a) (a) Costs for the design and construction of a grassed waterway or diversion to direct surface runoff around a sinkhole.

ATCP 50.87(2)(b) (b) Costs for the design and construction of a grassed waterway or diversion to direct surface runoff around a geologic depression to prevent the formation of a sinkhole.

ATCP 50.87(2)(c) (c) Costs for the design and construction of a modification to a sinkhole for the purpose of protecting groundwater resources from contamination.

ATCP 50.87(3) (3) Ineligible costs. A cost-share grant under s. ATCP 50.40 may not reimburse costs for any system, component, or practice that is not needed to correct an identified water pollution hazard.

ATCP 50.87(4) (4) Design, construction, and maintenance. A cost-share grant under s. ATCP 50.40 may not reimburse any costs related to sinkhole treatment unless all of the following conditions are met:

ATCP 50.87(4)(a) (a) The treatment complies with all of the following that apply:

ATCP 50.87(4)(a)1. 1. NRCS conservation practice standard 527 sinkhole treatment (September, 2021).

ATCP 50.87(4)(a)2. 2. NRCS conservation practice standard 362 diversion (August, 2016).

ATCP 50.87(4)(a)3. 3. NRCS conservation practice standard 412 grassed waterway (August, 2021).

ATCP 50.87(4)(b) (b) The landowner agrees to maintain the sinkhole treatment for 10 years unless farming operations on the affected land are discontinued.

In this section, “streambank or shoreline protection” means waterbody-specific treatments used to stabilize and protect the eroding banks of streams or constructed channels, and shorelines of lakes, reservoirs, or estuaries. The practice is designed and installed to provide water quality benefits or control soil erosion including degradation from livestock and may protect fish habitat as an incidental benefit. Streambank or shoreline protection may include any of the following components:
