10 CSR 20-6.011 Fees
Section 644.057, RSMo., passed as part of House Bill 28 earlier this year and signed by the governor on July 12, allows the Missouri Clean Water Commission to promulgate a clean water fee structure by rule. The present fee structure was established by statute in 2000. The Missouri Department of Natural Resources and stakeholders have reviewed the complete range of clean water activities conducted by the department and funding sources that support these efforts. The commission has proposed the clean water fees structure in this rulemaking together with other changes to the rule. The rule as published on Oct. 1, 2013 in the Missouri Register and, any edits as a result of the order are anticipated to be reviewed by the general assembly over a period of 60 days beginning in January 2014.

If the rule amendment is not disapproved by the general assembly, the order is to be published in the Missouri Register April 15, 2014 and published in the Code of State Regulations April 30, 2014 and, become effective May 30, 2014. The implementation date of the rule’s fee structure is effective Jan. 1, 2015.

10 CSR 20-7.015 Effluent Regulation
The primary purposes of this amendment include 1) revisions related to short-term E. coli limits and E. coli monitoring frequency, 2) revision to use the federal definition of bypass, 3) specify that operating permits may include schedules of compliance in accordance with federal regulations, 4) the removal of deadlines for attaining phosphorus limits because they will have passed by the time the regulation is effective, 5) the addition of language that details the different authorities for placing limits in permits, 6) the addition of language that clarifies the practice of placing whole effluent toxicity testing requirements and nitrate limits in certain permits, 7) a requirement for quarterly effluent monitoring for nutrients at large wastewater treatment plants, 8) language that would allow for reduced effluent monitoring frequencies at facilities that routinely meet limits and do no not have high variability, and 9) several other minor changes that will serve to better organize the regulation or that will clarify current permitting practices.

The order of rulemaking for effluent regulations will be published in the Missouri Register Jan. 15, 2014 and in the Code of State Regulations Jan. 31, 2014.
