ATCP 50.78(3)(3) Design and maintenance. A cost-share grant under s. ATCP 50.40 may not reimburse nutrient management costs under this section unless all of the following conditions are met: ATCP 50.78(3)(a)(a) The nutrient management practice complies with NRCS conservation practice standard 590 nutrient management (December, 2015). ATCP 50.78(3)(b)(b) The landowner agrees to maintain the nutrient management practice in each year for which cost-sharing is provided. ATCP 50.785(1)(1) Definition. In this section “nutrient treatment system” means a system installed to intercept subsurface (tile) flow, groundwater, or surface runoff flow to reduce the concentration of phosphorus or nitrate nitrogen and minimize the movement of these nutrients to surface water, or groundwater, or both. ATCP 50.785(2)(2) Eligible costs. A cost-share grant under s. ATCP 50.40 may reimburse any of the following costs related to a nutrient treatment system: ATCP 50.785(2)(b)(b) Costs to purchase and install necessary underground pipe, subsurface drain tile, outlets and other necessary structures for water control or mechanical outlets. ATCP 50.785(2)(c)(c) Costs to remove obstructions, if necessary for the installation of an effective nutrient management system. ATCP 50.785(2)(d)(d) 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 50.785(2)(e)(e) Cost to install permanent fencing to protect the nutrient treatment system. ATCP 50.785(2)(f)(f) Other nutrient treatment systems, approved by the department, that are needed to meet identified water quality objectives. ATCP 50.785(3)(3) Ineligible costs. A cost-share grant under s. ATCP 50.40 may not reimburse any of the following costs related to a nutrient treatment system: ATCP 50.785(3)(a)(a) Costs to design a nutrient treatment system that is not installed. ATCP 50.785(3)(b)(b) Costs of a proposed practice, to the extent that those costs exceed the cost of an equally effective alternative. ATCP 50.785(3)(c)(c) Costs for any system, component, or practice that is not required to correct an identified water pollution hazard. ATCP 50.785(3)(d)(d) Costs to install a nutrient treatment system in urban settings or that does not address agricultural runoff or drainage. ATCP 50.785(4)(4) Design, construction, and maintenance standards. A cost-share grant under s. ATCP 50.40 may not reimburse costs related to a nutrient treatment system unless all of the following conditions are met: ATCP 50.785(4)(a)(a) The nutrient treatment system complies with all of the following that apply: ATCP 50.785(4)(a)1.1. NRCS conservation practice standard 605 denitrifying bioreactor (June, 2021). ATCP 50.785(4)(a)2.2. NRCS conservation practice standard 782 phosphorus removal system (May, 2019).
