(ag) This chapter establishes compliance requirements that shall be incorporated into the quality systems of all laboratories accredited by the department.

(ar) Laboratories shall meet any requirements pertaining to analyses and analytical operations contained in the methods, regulations, or covered programs when those requirements are more stringent than the ones specified in this chapter, unless this chapter grants explicit, alternative allowances.

Note: Sources, including the following as updated, likely contain methods that are acceptable for testing under this chapter: The EPA, the department, Standard Methods for the Examination of Water and Wastewater, Test Methods for Evaluating Solid Waste, Physical/Chemical Methods - SW-846, American Society for Testing and Materials, and the U.S. Geological Survey Agency.

(b) When it is not apparent to the laboratory whether the minimum requirements of this chapter or those specified in the methods, regulations, or covered programs are more stringent, the department shall communicate which requirements are more stringent to the laboratories and the laboratories shall meet those requirements.

(c) When a laboratory incorporates a procedure that is neither expressly permitted nor prohibited by the method, the department will assess the scientific validity of the procedure to determine if the procedure is within the scope of the method. The underlying chemistry of the method shall remain unchanged. The department may seek the advice of the council in making determinations under this paragraph.
