ATCP 50.69 ATCP 50.69 Critical area stabilization.

ATCP 50.69(1) (1) Definition. In this section, “critical area stabilization” means planting suitable vegetation on erodible areas such as steep slopes and gullies, so as to reduce soil erosion or pollution from agricultural nonpoint sources. “Critical area stabilization” may also include treating areas that drain into bedrock crevices, openings, or sinkholes.

ATCP 50.69(2) (2) Eligible costs. A cost-share grant under s. ATCP 50.40 may reimburse the following critical area stabilization costs:

ATCP 50.69(2)(a) (a) Costs to purchase and install permanent fencing around the critical area.

ATCP 50.69(2)(b) (b) Costs to establish permanent vegetative cover, or to provide temporary cover until permanent cover is established. This may include costs for mulch, fertilizer, and other necessary materials.

ATCP 50.69(2)(c) (c) Preparatory shaping and smoothing operations.

ATCP 50.69(3) (3) Ineligible costs. A cost-share grant under s. ATCP 50.40 may not reimburse for the costs of planting trees intended for commercial harvest.

ATCP 50.69(4) (4) Design, construction, and maintenance. A cost-share grant under s. ATCP 50.40 may not reimburse critical area stabilization costs unless all of the following conditions are met:

ATCP 50.69(4)(a) (a) The critical area stabilization complies with all of the following that apply:

ATCP 50.69(4)(a)1. 1. NRCS conservation practice standard 342 critical area planting (January, 2018).

ATCP 50.69(4)(a)2. 2. NRCS conservation practice standard 382 fence (January, 2014).

ATCP 50.69(4)(a)3. 3. NRCS conservation practice standard 386 field border (January, 2017).

ATCP 50.69(4)(a)4. 4. NRCS conservation practice standard 472 access control (January, 2018).

ATCP 50.69(4)(a)5. 5. NRCS conservation practice standard 484 mulching (June, 2016).

ATCP 50.69(4)(a)6. 6. NRCS conservation practice standard 612 tree/shrub establishment (January, 2018).

ATCP 50.69(4)(a)7. 7. NRCS conservation practice standard 527 sinkhole treatment (September, 2021).

ATCP 50.69(4)(b) (b) The landowner agrees to maintain the critical area stabilization practice for 10 years unless farming operations on the affected land are discontinued or the practice is no longer required to prevent the soil and water resource problem for which the practice was installed.

ATCP 50.70 ATCP 50.70 Diversions.

ATCP 50.70(1) (1) Definition. In this section, “diversion” means a structure installed to divert excess surface runoff water to an area where it can be used, transported, or discharged without causing excessive soil erosion. A “diversion” can also be used to divert surface runoff water around farmsteads or agricultural waste systems to prevent water from becoming contaminated runoff, or both. “Diversion” includes a channel with a supporting earthen ridge on the lower side, installed across the slope with a self-discharging and non-erosive gradient.

ATCP 50.70(2) (2) Eligible costs. A cost-share grant under s. ATCP 50.40 may reimburse any of the following costs to establish a diversion system:

ATCP 50.70(2)(a) (a) Costs to install a diversion, outlet, dike, or subsurface drain. Costs to install a subsurface drain may be reimbursed only if the drain is installed on sloping land where groundwater seeps to the surface and causes the land or land cover to lose its stability.

ATCP 50.70(2)(b) (b) Costs to install pipes, underground outlets, or other structures needed to deliver water to a ditch or dike, to promote a more even flow of water, or to protect outlets from erosion.
