NR 151 rule changes for nitrate

See TAC section for updates and links to scheduled TAC meetings. For any questions regarding these changes, contact Chris Clayton.

As part of the effort to address groundwater issues and protect drinking water and public health across Wisconsin, the Department of Natural Resources worked with key public and agriculture industry stakeholders, state agencies, the State Legislature, the governor and the general public to update ch. NR 151, Wis. Adm. Code [exit DNR].

Background

Consistent with state statutes, NR 151 directs the DNR to promulgate rule performance standards to meet water quality standards and address specific issues either geographically or by activity. The NR 151 rule modification is to develop a targeted performance standard to abate nitrate pollution in areas of the state with highly permeable soils which are susceptible to groundwater contamination (sensitive areas) for the purpose of achieving compliance with the nitrate groundwater standards. The rule revisions will define sensitive areas in the state and the performance standards needed to protect groundwater quality in these areas.

Rule change process, public input and timeline

The Wisconsin DNR creates and revises administrative rules to implement statutes enacted by the Wisconsin State Legislature [exit DNR]. Administrative rules have the full force and effect of law.

Public participation is a critical component of agency rulemaking. There are numerous opportunities to participate in the DNR rulemaking process. There are many internal steps [PDF] that DNR and the Natural Resources Board (NRB) must go through during the rule promulgation process. For permanent rules, the entire process generally takes about 31 months from initiation to promulgation.

Preliminary public hearing

The Department of Natural Resources held preliminary public hearings on the statement of scope for proposed rule WT-19-19 related to targeted performance standards and prohibitions to abate pollution of groundwater by nitrate in sensitive areas on November 4th, 6th and 7th, 2019. Public comments were received through oral and written testimony provided at the public hearings and or submitted via email at DNRAdministrativeRulesComments@wisconsin.gov.

Technical Advisory Committee (TAC)

Given the size and scope of the effort required for rule changes of this type, and the need for technical input, DNR has formed a Technical Advisory Committee to provide guidance on the rule changes. The committee will be reviewing proposed changes to NR 151 to address targeted performance standards for sensitive areas of the state.

Six TAC meetings are currently scheduled at the locations listed below. The meetings will be public noticed, and prior to each meeting the department will provide an agenda and any materials for review. The TAC meetings are open to the public, and once the TAC meetings are completed, there will be additional opportunities for public input and comments throughout the remainder of the rule-making process.
