CR_13-112 Analytical methods used for Wisconsin Pollutant Discharge Elimination System (WPDES) compliance

Final Regulatory Flexibility Analysis

Clearinghouse Rule CR 13-112 Nat ural Resources Board Order SS-14 -12

This rule change will not have an impact on any entities or small businesses. It will only change the options for the analytical methods that a laboratory can use to analyze WPDES samples. There could be a small cost to laboratories that have been using SW 846 methods that will no longer be allowed. The cost would be for obtaining copies of allowed methods and staff time needed to update their methodology and change forms or other document that reference the SW 846 methods. The department believes that any change in test procedures should not significantly change the fees charged to permittees by laboratories. The department believes the impact will be minimal because the regulatory changes are very minor (insignificant impact on small businesses).
