The method shall be for analysis for the chemical without modification to the method parameters, quality assurance, or quality control criteria, unless allowed by the method; or
(C) If no method pursuant to subsection (b)(3)(A) or (b)(3)(B) is available for the chemical, a method developed by a laboratory, including modifications made to a method pursuant to subsection (b)(3)(A) or (b)(3)(B), may be proposed for use following submittal to the State Board of both the laboratory's standard operating procedure and a method validation package. Prior to submittal of the method validation package, the laboratory shall submit to the State Board a method validation plan that conforms to the US Environmental Protection Agency's Protocol for the Evaluation of Alternative Test Procedures for Organic and Inorganic Analytes in Drinking Water (EPA 815-R-15-007, February 2015), or Protocol for the Evaluation of Alternate Test Procedures for Analyzing Radioactive Contaminants in Drinking Water (EPA 815-R-15-008, February 2015), which are hereby incorporated by reference. A method that conforms to one of these protocols is acceptable to the State Board for use in a DPR project.
(c) Sample collection and field tests shall be performed pursuant to subsection 64415(b).
