Water Protection Program fact sheet
Division of Environmental Quality Director: Leanne Tippett Mosby

This document provides the Missouri Department of Natural Resources’ approval process for new or innovative wastewater technologies.  For the purpose of this document, the definition for new or innovative wastewater technologies, which mirrors the definition for innovative technology provided in section 644.051.12, RSMo; is as follows:

Innovative technology for wastewater treatment means a completely new and generally unproven technology in the type and method of its application that bench testing or theory suggest has environmental, efficiency, and cost benefits beyond the standard technologies.

The department encourages new methods and equipment for the treatment of wastewater and supports their development or use.  While new treatment methods and equipment are encouraged, the efficacy of the new methods and equipment must be demonstrated.  Typically this is accomplished by providing a theoretical overview of the technology, performing bench or pilot scale testing, and by demonstrating a full scale system.  An overview of this approval process is provided herein.  The applicant is encouraged to contact the Department of Natural Resources’ Water Protection Program prior to developing data to be used to demonstrate a new technology intended for use in Missouri. 

Small Scale Pilot Project for Innovative Technologies
The department may allow a temporary small scale pilot project to obtain data to demonstrate expected performance of a proposed technology.  These projects are to be installed such that the discharge is returned to and treated by the existing treatment facility.  Projects must be approved by the department prior to initiating testing.  A written request with a test plan must be submitted to the department in order to obtain the approval for the pilot test.  The request must contain the following information. 

The Test PlanThe testing to demonstrate the efficacy of the innovative technology must include, but may not be limited to, the following considerations:

The test plan should be submitted to the department’s Water Protection Program, Engineering Section for review prior to initiating testing efforts. Communication with the department during the course of the project is encouraged. 

After obtaining written project approval from the department, the project is exempt from obtaining a construction permit.  Pilot project installations may be used for up to one year and the evaluation requirement specifics are as stated above.  These installations are considered temporary and project requirements must be coordinated with the operating permits section to ensure water quality is protected.  The applicant may submit a written request with justification for a time extension to the department.  The department will review and may approve an extension period for up to one additional year.

Full Scale Demonstration Project for Innovative Technologies
In order to determine if the new process or equipment meets department standards, the results of a comprehensive, full-scale demonstration of the technology must be provided.  Three successful demonstration projects are required prior to advancing a technology out of an innovative status.

Prior to initiating an innovative or new technology demonstration project, the applicant is required to submit the appropriate permit applications and antidegradation evaluation.  The application must include the purpose of the project, a description of the innovative technology, the scientific basis for the technology, and the anticipated benefits of the technology.  If the process or equipment are to be demonstrated outside the State of Missouri, it must be demonstrated in a climate substantially the same as Missouri’s in order for it to be acceptable to the department. 

The operating permit for a facility performing a full scale demonstration project will contain additional requirements.  The monitoring frequency may be increased (e.g., every two weeks at designated locations), additional monitoring locations may be added (e.g., intermediate locations within the process), and monitoring additional parameters may be required (e.g., related to chemical and/or biological characteristics).  A Demonstration Project Report requirement will also be added for facilities performing a demonstration project.  After the innovative technology has been successfully demonstrated (e.g., typically after one year), monitoring requirements may be adjusted to a more typical scenario.

The Demonstration Project Report - Upon completion of the demonstration project, a report that presents the findings of the testing and engineering evaluation must be prepared.   The report should include, but may not be limited to the following:

The department recommends the applicant review 10 CSR 20-8.110, Engineering – Reports, Plans, and Specifications, for assistance in determining the types of information relevant in the Demonstration Project Report.

The department may approve innovative technologies or equipment in accordance with 10 CSR 20-8.020(11)(B)2 and 10 CSR 20-8.140(5)(B), under the following conditions:

The department may require the innovative technology demonstration be performed by an independent third party.  Resumes of the principal investigators may be requested.
