NAC445A.8585. Establishment of concentration level for contaminant.

Latest version.

If a maximum contaminant level has not been established for a contaminant, a concentration level for the contaminant may be established by using:

1. The naturally occurring background concentration of the contaminant; or

2. An appropriate level of concentration based on the protection of public health and safety and the environment. The appropriate level of concentration of a contaminant must be determined by the Division using the Integrated Risk Information System adopted by reference pursuant to NAC 445A.2272, or an equivalent method approved by the Division.
