The city of Monett requested approval to implement and enforce a modification to its approved wastewater pretreatment program. The department reviewed the proposal and intends to approve the plan modification. The department invites the public to review and offer written comments on the proposed pretreatment program modification until Aug. 10, 2026. All comments must be received or postmarked by 5 p.m. The public can review the proposed program modification below. Other relevant information is available for review and copying upon request.
The city is proposing to amend local limits, which includes omitting arsenic, copper, selenium and zinc, due to loadings not sufficient to cause potential of pass through or interference. The proposed local limit revisions include updating Biological Oxygen Demand (BOD) and Total Suspended Solids (TSS), and adopting Total Kjeldahl Nitrogen (TKN). The city proposes to adopt these local limits into the city’s legal authority as maximum allowable industrial loading (MAIL) and implement as maximum daily limits, allocated based on need. The city’s modification also includes Enforcement Response Plan updates and Sewer Use Ordinance (SUO) modifications to reflect changes related to the local limit updates. The city’s pretreatment program changes were designated substantial modifications because these changes could have a significant impact on the operation of the program, pursuant to 40 CFR 403.18(b)(7).
Written comments may be submitted by mail to Missouri Department of Natural Resources, Water Protection Program, ATTN: Pretreatment Coordinator, PO Box 176, Jefferson City, MO 65102-0176 or by email to pretreatment@dnr.mo.gov. Please include the permit number in the comment letter. The department can only consider comments about issues relating to the proposed action. The department cannot consider comments or objections based on issues outside the authority of the Missouri Clean Water Commission. The proposed department approval is tentative pending public comment. The notice of request for approval will be approved if no comments are received by the date specified in this notice, no substantive comments are received, and the request is approved without change.
