PUB2453

This document provides the Missouri Department of Natural Resources’ interim definitions for new or innovative wastewater technologies, until the regulations may be amended.

The department encourages new methods and equipment for the treatment of wastewater. In accordance with 10 CSR 20-8.020(11)(B)2 and 10 CSR 20-8.140(5)(B), the following information shall be provided to evaluate new technology.

The following are interim definitions and examples of each stage of new technology determined by the department. Every new technology is evaluated by each individual effluent parameter.

Proven Technology
Definition:
Existing technology not in the Code of State Regulations (10 CSR 20-8), but has been in use for many years, is common throughout the United States and is considered effective when properly operated and maintained.

Proven technologies will be added to 10 CSR 20-8 as soon as is practical. Department approvals are effluent parameter specific.

Examples

Treatment Technology

Effluent Parameter(s)

Recirculating Sand Filter

BOD5, TSS

Sequencing Batch Reactor

BOD5, TSS, Ammonia

Ultraviolet Disinfection

Bacteria such as E. coli

Developing Technology
Definition:
Newer technologies not covered in 10 CSR 20-8, but do have an established performance record, which includes three separate full-scale installations in the United States operating at a minimum of 75 percent of design average flow for three years, and having performed consistently as designed without major failure of the process, unit or equipment.

Department approvals are parameter specific.

Examples

Treatment Technology

Effluent Parameter(s)

Membrane Bioreactor (MBR)

BOD5, TSS, Ammonia

Recirculating Sand Filter

Ammonia

Unproven Technology
Definition:
Emerging technologies not covered in 10 CSR 20-8. These are technologies undergoing pilot scale, or field application testing, or have already been applied in the field for full-scale application, but do not meet the criteria for developing technology.

Examples

Treatment Technology

Effluent Parameter(s)

Moving Bed Bioreactor (MBBR)

BOD5, TSS, Ammonia

Peracetic Acid

Bacteria such as E. coli

These projects will be reviewed for approval under the following conditions: The operational reliability and effectiveness of the process or device shall have been demonstrated with a suitably sized prototype unit operating at its design load conditions for a minimum of one year with samples collected once per week and meeting the 90th percentile criteria (using the Microsoft® Excel® equation). Each permit parameter will be reviewed and approvals are parameter specific.

To determine such new processes and equipment or applications have a reasonable and substantial chance of success, the following will be required in the engineering report:
