A cost-share grant under s. ATCP 50.40 may reimburse the cost of designing and constructing a sediment basin, including costs for heavy use area protection, livestock fencing, filter strips, waste transfer, underground outlets, and critical area plantings.(3) INELIGIBLE COSTS. A cost-share grant under s.
