Silica Sand Rulemaking

DNR's role in rulemaking for the reclamation of silica sand mines



In response to concern about silica sand mining and related activities, legislation was passed giving three state agencies authority to develop new rules to regulate silica sand projects:

  • Reclamation of silica sand mines - rules to be developed by the DNR.
  • Control of particulate emissions from silica sand projects - rules to be adopted by MPCA.
  • Environmental review for silica sand projects - rules will be amended by the EQB.

All three state agencies are coordinating their silica sand rulemaking efforts. A joint advisory panel has been assembled and is currently meeting monthly.

Legislative authority


Status of rules

As of April 2014, the DNR intends to spend the next several months on the following items:

  • Developing the scope of the rules
  • Drafting rule language
  • Writing a State of Need and Reasonableness or SONAR

Promulgating rules can take about two years. The process can take longer for complex rules and to accommodate higher levels of public participation. When the draft rules are finished, they will be posted and available for public comment.
