(a) Each handler shall report on or before the 15th day after the end of each month the information required by the market administrator with respect to producer additions, producer withdrawals, changes in farm locations, and changes in the name of farm operators.

(b) Each handler that is not a cooperative association, upon request from any such association, shall furnish it with information with respect to each of its producer members from whose farm the handler begins, resumes, or stops receiving milk at his pool plant. Such information shall include the applicable date, the producer-member's post office address and farm location, and, if known, the plant at which his milk was previously received, or the reason for the handler's failure to continue receiving milk from his farm. In lieu of providing the information directly to the association, the handler may authorize the market administrator to furnish the association with such information, derived from the handler's reports and records.

(c) Each handler shall submit to the market administrator, within 10 days after his request made not earlier than 20 days after the end of the month, his producer payroll for the month, which shall show for each producer:

(1) The daily and total pounds of milk delivered and its average butterfat test; and

(2) The net amount of the handler's payments to the producer, with the prices, deductions, and charges involved.
