The regulatory impact report (RIR) for proposed revisions to 10 CSR 20-7.015, Effluent Regulations, is available for public review and comment until Nov. 21, 2022. Written comments may be submitted by mail to Missouri Department of Natural Resources, Water Quality Section, P.O. Box 176, Jefferson City, MO 65102-0176 or online through the Regulatory Action Tracking System. Please include the rule number and your contact information: name, email address and phone number.
An RIR is required at the beginning of the rulemaking process for rules recommending environmental standards or conditions. It documents the environmental and economic costs and benefits associated with the proposed rule changes. The department invites the public to review and submit comments to help ensure that our regulations provide required protections but do not add unneeded costs. Only the RIR is open for public comment at this time. The proposed rule will be open for public comment at a later date.
The proposed rule amendment will implement statewide effluent limitations for Total Phosphorus and incorporate deleted language regarding losing streams from the Water Quality Standards regulations. The statewide Total Phosphorus limit is necessary to implement a recommended action item from the 2014 Missouri Nutrient Loss reduction Strategy and to compliment and improve Missouri's waters that are not captured under the scope of numeric nutrient criteria for lakes. Reference to Table J will also be removed as it currently references Water Quality Standards Variances, and will now reference a geospatial data set currently maintained by the Missouri Geological Survey. For additional details please see the rulemaking report.
