ATCP 65.86(3)(g)(g) Calibration and daily performance check samples; total solids. ATCP 65.86(3)(g)1.1. The provider of a calibration sample under par. (b) or a daily performance check sample under par. (c) shall determine the known percentage content of total solids in that sample by averaging the results of 3 total solids tests using the method specified under subd. 3. The percentage total solids results from those 3 tests shall not vary by more than 0.054 percentage points. ATCP 65.86(3)(g)2.2. The known total solids content of a calibration or daily performance check sample, expressed as a percentage of sample weight, shall be at least 11%. Within a set of calibration samples, the difference in known total solids content between the lowest total solids sample and the highest total solids sample, expressed as a percentage of average sample weight, shall be at least 2.00%. Within a set of daily performance check samples, the difference in known total solids content between the lowest total solids sample and the highest total solids sample, expressed as a percentage of average sample weight, shall be at least 1.5%. ATCP 65.86(3)(g)3.3. To determine the total solids content of a calibration sample or daily performance check sample, the sample provider shall use the direct forced air oven drying method as described in the “Official Methods of Analysis of AOAC International,” 18th edition (2005), section 990.20.

(e) from the total solids for that sample as determined under par. (g). The calculation method shall be that described in the “Official Methods of Analysis of AOAC International,” 18th edition (2005), section 990.21.

A dairy plant operator shall keep a record of every calibration, performance check, or reference check conducted on a milk component testing device under this section. ATCP 65.86(3)(j)2.2. Every record required under subd. 1 shall be signed by the licensed tester who made the record. Calibration records shall be kept separate from performance check and reference check records.

ATCP 65.910ATCP 65.910 Inspection of dairy farms; general. ATCP 65.910(1)(1) Inspection by dairy plant operator. Before a dairy plant operator, including a milk contractor that submits a milk producer license application on behalf of a milk producer and thereby certifies that the milk producer’s dairy farm and milking operations comply with applicable requirements under this chapter, submits a milk producer license application or a grade A permit application under s. ATCP 65.02 on behalf of a milk producer, the dairy plant operator shall inspect the dairy farm for compliance with the dairy farm standards under subch. II. The dairy plant operator, when submitting the producer’s license or permit application, shall include a copy of the dairy plant operator’s inspection report and shall certify that the dairy farm facilities comply with dairy farm standards under subch. II. The department may, at other times, require a dairy plant operator to inspect a dairy farm as necessary. ATCP 65.910(2)(2) Inspection by the division. The division shall inspect dairy farms for compliance with dairy farm standards under subch. II. The division shall inspect a grade A dairy farm at the frequency given in s. ATCP 65.912 and a grade B dairy farm at least once every year. For the purpose of conducting a lawful inspection under this chapter, the department may exercise its authority under ss. 93.08, 93.15 (2), and 97.12 (1), Stats. ATCP 65.910(3)(3) Variances. The division administrator, or the division administrator’s designee, may issue a written waiver granting a variance from a dairy farm standard under subch. II if the division determines that the variance is reasonable and necessary under the circumstances, it will not compromise the purpose served by the standard, and the milk producer does not hold a grade A farm permit.

The division shall use the performance standards in this section to determine grade A dairy farm inspection frequency. The division shall evaluate each grade A dairy farm every 3 months, on the basis of information including inspection reports, milk quality tests, and department compliance actions taken during the preceding 12 months. As provided in subs. (2) to (5), the division shall place each dairy farm in one of the following categories: ATCP 65.912(2)(2) Twelve-month inspection interval. The division shall inspect a grade A dairy farm in the twelve-month inspection interval category at least once every 12 months. The division shall place a dairy farm in this category if all the following apply, based on dairy farm inspection reports, milk quality tests, and department compliance actions, during the preceding 12 months: ATCP 65.912(2)(a)(a) None of the milk producer’s reported standard plate count (SPC) results exceed 25,000 per ml., except that one reported SPC result may exceed 25,000 per ml. if it is not more than 100,000 per ml. ATCP 65.912(2)(b)(b) None of the milk producer’s reported somatic cell count (SCC) results exceed 500,000 per ml.
