6 CCR 1007-3-260.12 - Sampling and Analytical Methods

(a) Except where these regulations require the use of specific sampling or analytical methods identified in SW-846 or another publication incorporated by reference in § 260.11, whenever the Department finds, based on tests, studies, or other information, that the sampling or analytical methods proposed for use or in use at a particular site or facility are inadequate to achieve the performance objectives of the activity, the Department may require use of alternative methods which the Department finds are adequate to meet the performance objectives of the activity, including sensitivity, accuracy, precision (i.e. reproducibility), and safety. In making the findings described above, the Department shall consider relevant factors and information, including:

(1) the procedural steps and equipment used in the method;

(2) the types of wastes or waste matrices for which the proposed method may be used;

(3) factors which may interfere with, or limit the use of, the method;

(4) quality control procedures necessary to ensure the sensitivity, accuracy, and precision of the method;

(5) supporting tests, studies and other information; and

(6) where these regulations recommend, but do not require, a particular method to be used, data comparing results from the method under consideration with results from the recommended method.

(b) Except where these regulations require the use of specific sampling or analytical methods identified in SW-846 or another publication incorporated by reference in § 260.11, any person may request the Department to approve a sampling or analytical method for use at a specified site or facility. Any person making such a request shall submit the following information:

(1) the name and address of the site or facility;

(2) a full description of the proposed method, including all procedural steps and equipment used in the method;

(3) a description of the types of wastes or waste matrices for which the proposed method may be used;

(4) an assessment of any factors which may interfere with, or limit the use of, the proposed method;

(5) a description of the quality control procedures necessary to ensure the sensitivity, accuracy and precision of the proposed method;

(6) supporting tests, studies, or other information; and

(7) where these regulations recommend, but do not require, a particular method to be used, or where the Department has previously required an alternative method, data comparing results from the method under consideration with results from the recommended or previously required method.

If the Department finds, based on tests, studies, or other information, that sampling or analytical methods proposed for use by any person are adequate to meet the performance objectives of the activity, including sensitivity, accuracy, precision (i.e. reproducibility), and safety, the Department may approve use of the methods at a specified site or facility.

(c) In cases where these regulations require the use of specific sampling or analytical methods identified in SW-846, or another publication incorporated by reference in § 260.11, alternate sampling and analytical methods may only be approved by rulemaking petition, as provided in § § 260.20 and 260.21.
