19 CSR 20-3060: Minimum Construction Standards for On-Site Sewage Disposal Systems Department of Natural
Resources Division 20 - Clean Water Commission 10 CSR 20-8.021 Chapter 8 - Design
Guidelines Regulations on individual sewage treatment systems (domestic flows less than 3000 gallons/day and single family lagoons) in Missouri are presently found in 19 CSR 20-3060, last updated in October 1995. Currently, the Missouri Department of Health (DOH) is in the process of rewriting this rule. The Missouri Department of Natural Resources (DNR) regulates: onsite systems with greater than 3000 gallons/day domestic flows, all non-domestic flows, and all surface discharge systems. These regulations were last updated January 3, 1992 and are currently being reviewed for revision. The state of Missouri is not considering the implementation of performance based standards. Aerobic treatment units (ATUs) must have National Sanitation Foundation (NSF) certification. Gravelless/Chamber systems, mounds, sand filters, low pressure pipe (LPP), lagoons, and constructed wetlands are alternative technologies included in current Missouri onsite regulations. Drip irrigation systems are contained within the regulations, but must be designed by an engineer. Technologies allowed by exception or variance are considered alternative systems and are based on site limitations, i.e. infiltration size, minimum separation distances from wells, restrictive horizons, property lines, etc. Most can be approved through requesting a variance; however, the design must be from a licensed engineer, and provide adequate treatment to improve the quality of effluent being released. At this time the DOH has other functions which are called core public health functions. The DOH does not have enough resources to provide a management program to monitor and maintain onsite wastewater systems. Rural Development and the Community Action Agency have money available to assist homeowners with replacement of failing systems or installation of new systems. For more information, contact Mr. Gary Frisch with Rural Development at (573) 876-0990, or Mr. David Thayer with the Community Action Agency at (573) 443-8706. The DNR have a low income grant which is funded by the Federal Government. The DOH does not have such a program. In this instance, the individual homeowner is responsible for finding any other resources that may assist them. The DOH administers an onsite certification program for contractors and installers. Installers are required to be registered with the State. For more information, contact Joe Hainline with the DOH. The state of Missouri has a voluntary installer registration which requires the Department of Health to publish the names of the individuals on a public list. As of July 1, 1998 under the existing law, the Department has decided to license private inspectors to evaluate existing onsite waste disposal systems. Contact Mr. Hainline or Mr. Johnson for further information at the address and/or telephone number listed above. Mr. Hainline can also be contacted for more information concerning the Missouri Smallflows Organization, the state's onsite wastewater association, and the onsite training center. Mr. Tod Hudson with the DNR, can be contacted at (573) 751-8728, concerning ongoing demonstration, research, and testing projects within the state. The DOH does not produce a newsletter or bulletin concerning onsite technologies or information concerning regulatory updates; however, the DOH does provide "informational releases" to the other state level and local level regulatory agencies. The DNR regulates large municipal septic
systems. For more information, contact Mr. Leland Neher with the DNR at (573)
