If the Secretary determines it is necessary to improve or expedite an amendatory formal rulemaking proceeding to amend a Federal milk marketing agreement or order, USDA may impose an assessment on pooled milk to supplement appropriated funds for the procurement of such services, including but not limited to, court reporters, hearing examiners, legal counsel, hearing venue and associated travel for USDA officials. Only the milk pooled in the particular marketing area that stands to be affected by proposals heard at the amendatory proceeding may be assessed. The assessments shall be subject to the provisions of §1000.85 (7 CFR 1000.85) concerning assessments for order administration, including the provision that assessments shall not exceed $.005 per hundredweight of milk for any given month.
