DATCP Updates AST Threshold for Regulation

Article Posted: 2019-09-23


On March 29, 2019, DATCP submitted its Biennial Report Reviewing Administrative Rules to the Joint Committee for Review of Administrative Rules, as required under Wisconsin Statute § 227.29 (1). DATCP reported that certain portions of Wisconsin Administrative Code Chapter ATCP 93 conflict with Wis. Stat. § 168.22 (3). In the report, the Department recommended a statutory change to align the statute’s 5,000-gallon threshold with the administrative code’s 110-gallon threshold.

To date, no statutory change has occurred. As a result, effective October 1, 2019, DATCP will no longer enforce portions of ATCP 93 that conflict with Chapter 168. DATCP has developed this list of frequently asked questions to assist in understanding how these changes affect the program.
