Cost-share payments will be made available upon a determination by the Deputy Administrator that an eligible practice, or an identifiable unit thereof, has been established in compliance with the appropriate standards and specifications.

Except as otherwise provided for in this part, cost-share payments may be made only for the cost-effective establishment or installation of an eligible practice, as determined by the Deputy Administrator.

Except as provided in paragraph (d) of this section, cost-share payments shall not be made to the same owner or operator on the same acreage for any eligible practices that have been previously established, or for which such owner or operator has received cost-share assistance from any Federal agency.

Except as provided for under § 1410.9(c), cost-share payments may be authorized for the replacement or restoration of practices for which cost-share assistance has been previously allowed under the CRP, only if:

Replacement or restoration of the practice is needed to achieve adequate erosion control, enhance water quality, wildlife habitat, or increase protection of public wellheads, grassland improvement, or other conservation measures, as determined by the Deputy Administrator; and

The failure of the original practice was due to reasons beyond the control of the participant.

The cost-share payment made to a participant will not exceed the participant's actual contribution to the cost of establishing the practice and the amount of the cost-share may not be an amount that, when added to such assistance from other sources, exceeds the cost of the practices.

CCC will not make cost-share payments with respect to a CRP contract if any other Federal cost-share assistance has been, or is being, made with respect to the establishment of the cover crop on land subject to such contract.

The Deputy Administrator may make cost-share payments for thinning of existing tree stands to benefit wildlife habitat and other resource conditions on enrolled land, as determined by the Deputy Administrator.
