020-1 Wyo. Code R. § 1-10
For determination of the parameters involved in the standards, analyses will be in accordance with test procedures defined pursuant to: Title 40, Code of Federal Regulations, Part 136, or any modifications thereto. For test procedures not listed in the Code of Federal Regulations, test procedures outlined in the latest editions of: EPA Methods for Chemical Analysis of Water and Wastes; Standard Methods for the Examination of Water and Wastewaters; or ASTM Standards shall be used.
Where standard methods of testing have not been established, the suitability of testing procedures shall be determined by the department and the EPA using defensible scientific methods.
Numeric criteria included in the standards represent levels necessary to protect designated uses and do not necessarily reflect detection limits that can be achieved using standard analytical techniques. Standard analytical techniques are considered during development of discharge permits and evaluation of water quality data. Sampling entities should consult with the department to determine reporting limit needs to ensure that adequate testing procedures and reporting limits are requested from the laboratory.
