ATCP 50.08(1)(1) General. A landowner engaged in agricultural practices in this state is not required to do any of the following, under s. ATCP 50.04, unless the landowner receives a bona fide offer of cost-sharing: ATCP 50.08(1)(a)(a) Discontinue or modify cropping practices on existing cropland. In this paragraph, “existing cropland” has the meaning given in s. NR 151.09 (4) (b). ATCP 50.08(1)(b)(b) Discontinue or modify an existing livestock facility or operation. In this paragraph, “existing livestock facility or operation” has the meaning given in s. NR 151.095 (5) (b). ATCP 50.08(2)(2) Cost-share amount. A cost-share offer under sub. (1) shall cover at least 70% of the landowner’s cost to install and maintain each required conservation practice, or 90% of the landowner’s cost if there is an economic hardship under s. ATCP 50.42 (4). ATCP 50.08(3)(3) Landowner’s cost. A landowner’s cost to install and maintain a conservation practice includes all of the following that apply: ATCP 50.08(3)(a)(a) The landowner’s reasonable and necessary expenditures to install and maintain the conservation practice. This includes eligible installation costs identified in subch. VIII, and costs for engineering services under s. ATCP 50.40 (7). ATCP 50.08(3)(b)(b) The reasonable value of necessary labor, equipment, and supplies provided by the landowner in the installation and maintenance of the conservation practice for the period required under subch. VIII or specified in the contract. This does not include normal operating routines such as clean-outs of barnyards, storage facilities, and gutters. ATCP 50.08(3)(d)(d) The landowner’s cost to take or keep land out of agricultural production, if the landowner must take or keep more than ½ acre out of agricultural production in order to install or maintain the conservation practice. The landowner’s cost, determined on the date of the cost-share contract, equals the sum of the annual costs that the landowner will incur over the maintenance period specified in the cost-share contract. The landowner’s annual cost, for each year of the maintenance period, equals the number of affected acres multiplied by the per-acre weighted average soil rental rate in the county on the date of the cost-share contract. This paragraph does not apply to land directly occupied by a facility or structure, such as a manure storage facility, that a landowner installs as part of the conservation practice. ATCP 50.08(4)(4) Riparian land taken out of production; crep-equivalent payment. ATCP 50.08(4)(a)(a) If a landowner must take or keep more than ½ acre of riparian land out of agricultural production in order to install or maintain a conservation practice, the cost-share offer under sub. (1) for that conservation practice shall be at least equal to the amount that would be offered under the CREP program if the affected lands were enrolled in that program, regardless of whether the lands are actually eligible for the CREP program. ATCP 50.08(4)(b)(b) Paragraph (a) does not apply unless the landowner agrees to keep the land out of agricultural production for 15 years, or in perpetuity, under contract terms equivalent to those that apply under the CREP program. ATCP 50.08(4)(c)(c) Paragraph (a) does not apply to a cost-share offer made after the CREP program expires. ATCP 50.08(4)(d)(d) Paragraph (a) does not apply to land directly occupied by a facility or structure, such as a manure storage facility, that a landowner installs as part of the conservation practice.
