Under Gov. Greitens' leadership, all state agencies are working to reduce regulations or other government processes that unnecessarily burden individuals and businesses while doing little to protect or improve public health, safety and our natural resources. The Missouri Department of Natural Resources is committed to limiting regulation to what is necessary to protect Missouri's environment, implement statutory mandates and maintain state control of programs. Any proposed changes to rules discussed on this page are being developed with these goals in mind. We welcome your comments to help insure that our regulations provide required protections but do not add unneeded costs.If you wish to provide comments on any existing department regulation, please visit the department’s Red Tape Reduction website.

10 CSR 20-7.031 - Water Quality Standards
An amendment to Missouri Water Quality Standards has been published in the Oct. 16, 2017 Missouri Register (Volume 42, Number 20). The proposed amendment can be found from pages 1424 - 1539 of the MoReg at the following link: https://www.sos.mo.gov/CMSImages/AdRules/moreg/2017/v42n20Oct16/v42n20a.pdf
Anyone may file a statement in support of, or in opposition to, this proposed amendment with the Department of Natural Resources, Division of Environmental Quality, Water Protection Program, Attn: WQS Coordinator, PO Box 176, Jefferson City, MO 65102. Comments may also be submitted online at https://dnr.mo.gov/proposed-rules. Public comments must be received by Nov. 28, 2017. The public hearing is scheduled to be held at 9 am on Nov. 21, 2017 at the Department of Natural Resources, Lewis and CLark State Office Building, LaCharrette Conference Room, 1101 Riverside Dr., Jefferson City, MO 65101.
The purpose of this rulemaking is to update Missouri's Water Quality Standards. Several of the revisions are a result of stakeholder input gathered during the department's "Public Notice of Intent to Initiate Triennial Review of Missouri Water Quality Standards" and subsequent Water Protection Forum and Water Quality Standards workgroup meetings. Priorities established as a result of this process include addressing U.S. Environmental Protection Agency (EPA) disapproved items (i.e. numeric nutrient criteria for lakes), updating water quality criteria for pH and other pollutants, and changes to sections describing mixing zones, general criteria, and existing definitions. Portions of this rule require a Regulatory Impact Report pursuant to Chapter 536 RSMo.
A new Regulatory Impact Report (RIR) is now available that revises the report originally filed July 24, 2017. It has been revised to reflect key changes to the proposed rule, including removing the drinking water use and reassignment of Truman Lake to the Plains ecoregion. The report documents the environmental impact and economic costs and benefits associated with all the proposed changes. The revised RIR comment period is Sept. 25, 2017 through Nov. 24, 2017.
