MPCA rulemaking for silica sand

Laws of Minnesota 2013, Chapter 114, Article 4, Section 105, directs the MPCA to develop rules for the control of particulate emissions from silica sand projects.

Requests for comments

The MPCA issued a request for comments on July 22, 2013, to get input on the proposed rule.

Second request for comments (September 2014); deadline for comments extended to Nov. 21, 2014.


The MPCA is still considering the scope of the entire silica sand rulemaking. The initial request for comments on possible rules is very broad to allow for the agency to also consider including water pollution from silica sand projects in the rulemaking.

While the MPCA has not developed an exact schedule, it intends to spend 4 to 6 months developing the rule scope after the close of the comment period (Sept. 30, 2013) on the initial Request for Comments. After that, the MPCA expects to spend another 6 months drafting rule language and a Statement of Need and Reasonableness (SONAR) to propose for public comment. It normally takes about two years to promulgate rules, but this can take longer based on complexity of rules and the level of public participation. The MPCA encourages interested parties to register for notification with GovDelivery on the MPCA’s main webpage. The MPCA will continue to update this page as events occur.

Several Minnesota state agencies are involved in implementing the 2013 legislation regarding silica sand mining, processing and transportation in Minnesota. An interagency website has been developed to help track progress across all agencies.

Advisory panel

The MPCA and Minnesota Department of Natural Resources (MDNR) have formed a joint advisory panel that will provide input to the agencies as they consider possible rulemaking for the regulation of silica sand operations in Minnesota.
