Water Protection Program Rule Development
The following rule developments are being considered. The Regulatory Impact Report provides information on the rule development. Please provide comments in the time frames indicated. All comments received will be posted with responses prior to filing as a proposed rulemaking. Once filed and published in the Missouri Register, there will be another opportunity to comment during the proposed rulemaking open comment period and public hearing prior to adoption. Thank you for your interest and assistance in developing these rules.
10 CSR 60-3.010 Construction Authorization, Final Approval of Construction, Owner-supervised Program and Permit to Dispense Water
The amendment updates the incorporation by reference of the noncommunity design standards. Standards for Noncommunity Public Water Supplies, 1982 will be replaced with Minimum Design Standards for Missouri Noncommunity Public Water Supplies (2013).
Revised Total Coliform Rule: The Department of Natural Resources is in the process of proposing a rulemaking to adopt the U.S. Environmental Protection Agency’s Revised Total Coliform Rule (RTCR). This rulemaking will require amending eight drinking water rules and adopting one additional rule. All of these amendments and the new rule constitute one rulemaking.
10 CSR 60-2.015 Definitions: The amendment adopts definitions from the RTCR for clean compliance history, level one and level two assessments, sanitary defect, and seasonal system. Draft
10 CSR 60-4.020 Maximum Microbiological Contaminant Levels and Monitoring Requirements: The amendment adds a section explaining when the total coliform monitoring requirements will be replaced with the Revised Total Coliform Rule. Draft
10 CSR 60-4.025 Ground Water Rule Monitoring and Treatment Technique Requirements: The amendment modifies triggered source water monitoring requirements to include RTCR provisions. The RTCR requires triggered source water monitoring under certain conditions and allows very small ground water systems to use a repeat sample to meet the requirements of both the RTCR and the GWR under certain conditions specified in the RTCR. Draft
10 CSR 60-4.055 Disinfection Requirements: The amendment will require all public water systems that use chlorine or chloramines to measure the residual disinfectant level in the distribution system at the same point in the distribution system and at the same time as total coliforms are sampled. Draft
10 CSR 60-7.010 Reporting Requirements: The amendment adopts reporting requirements from the RTCR for E. coli MCL violations, coliform treatment technique violations, assessment reports, corrective actions, monitoring violations, and seasonal system certifications. Draft
10 CSR 60-8.010 Public Notification of Conditions Affecting a Public Water Supply: The amendment adds RTCR requirements to Tier 1 and Tier 2 public notice as applicable. Tier 1 notice is required for violation of the E. coli MCL. Tier 2 public notice must be repeated every three months for RTCR MCL and treatment technique violations as long as the violation or situation persists. Draft
10 CSR 60-8.030 Consumer Confidence Reports: The amendment requires the Consumer Confidence Report to include information on Level 1 and Level 2 assessments and the total number of positive E. coli samples, if any. Draft
10 CSR 60-9.010 Requirements for Maintaining Public Water System Records: The amendment adopts recordkeeping requirements of the RTCR. The water system must maintain assessment forms and documentation of corrective actions for at least five years after completion of the assessment or corrective action. Draft
10 CSR 60-4.022 Revised Total Coliform Rule (new rule): This proposed rule adopts 40 CFR part 141 subpart Y, except for those sections that fit more appropriately as amendments into our existing rule structure and are described above. The purpose of the rule is to increase public health protection by reducing potential pathways of entry for fecal contamination into distribution systems. The rule uses E. coli and total coliforms to initiate a “find and fix” approach to address problems that could let fecal contamination enter the distribution system. System self-assessments will be required when certain total coliform or E. Coli triggers are exceeded. Sanitary defects must be identified and corrective action must be taken. The RTCR defines seasonal systems and sets monitoring requirements for these systems. At the beginning of each operating period, before serving water to the public, seasonal systems must conduct state-approved start-up procedures. Draft

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 order was 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 20-7.031 - 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.
