WDNR Runoff Standards - Proposed Amendment to NR 151

The Wisconsin Department of Natural Resources (WDNR) is currently in the process of making revisions to Wisconsin Rule NR 151. NR 151establishes runoff pollution performance standards for non−agricultural facilities and transportation facilities and performance standards and prohibitions for agricultural facilities and practices designed to achieve water quality standards.

The WDNR has proposed amendments that include:

  • develop an agricultural buffer or equivalent performance standard and a performance standard to address sediment, manure and other runoff from smaller, non-permitted farms;
  • modify post-construction non-agricultural performance standards, regarding infiltration and protective areas;
  • revise existing agricultural performance standards and prohibitions to clarify provisions related to manure storage facility closures and direct runoff of manure; and
  • modify grant rules pertaining to eligibility, awards, allocation for TMDLs and project size.

A formal proposal for amendments is expected to be released for public comment in 2009.
