Orders of Rulemaking


Water Pollution Control Branch

10 CSR 20-6.300 Concentrated Animal Feeding Operations
The primary purpose of the rulemaking is to ensure 10 CSR 20-6.300 is consistent with section 640.700 RSMo as provided for on Aug. 28, 2013 in House Bill 28, which removed most construction permit requirements for concentrated animal feeding operations. In addition to current changes resulting from the state statute as amended in 2013, the department is proposing minor revisions to definitions and language.

10 CSR 20-8.300 Manure Storage Design Regulations
This rulemaking removes the construction permitting requirement for concentrated animal feeding operations without earthen basins, improves and adds several definitions, clarifies items required in an application for engineering review, changes the name of the Division of Geology and Land Survey to Missouri Geological Survey, and removes nutrient management plan requirements and other documents required for operating permits.

10 CSR 20-7.031 - Water Quality Standards
The department appreciates the comments and items for rulemaking provided by the public in response to the Public Notice of Intent to Initiate Triennial Review.  Discussions at the June 26 Water Protection Forum and the July 9 Clean Water Commission meetings were productive in refining the list of items to be proposed and providing timeline for the rulemaking.  A Water Quality Standards Stakeholder meeting was held July 30 at the Lewis and Clark State Office Building to further refine the list of items for rulemaking and the rationale for those revisions.  The department is currently developing a Regulatory Impact Report for the rulemaking in accordance with the schedule provided by the Clean Water Commission.  The report and supporting documents will be published in the near future.

10 CSR 20-8.500 - Agrichemical
The purpose of this rule is to remove the requirement that agrichemical facilities without earthen basins obtain construction permits. Agrichemical facilities are sites where bulk agrichemicals are stored in non-mobile containers or dedicated containers and are being mixed, applied, repackaged or transferred between containers. Agrichemicals include any pesticides or fertilizers but do not include anhydrous ammonia fertilizer. Although a construction permit will no longer be required for Agrichemical facilities, they must continue to be constructed according to the design criteria detailed in rule.
