The city of Rolla currently has an approved pretreatment program to meet the requirements of the Clean Water Law. The city of Rolla submitted a proposed modification to that pretreatment program. The department reviewed the proposal and intends to approve the modification. The department invites the public to review and offer written comments on the proposed pretreatment program modification until June 13, 2022. All comments must be received or postmarked by 5 p.m. The public can review the proposed permit conditions below. Other relevant information is available for review and copying upon request.
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 todd.blanc@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 modification request will be approved if no comments are received by the date specified in this notice; where no substantive comments are received, the notice of intent for approval is approved without change.
The city is proposing modifications to adopt the U.S. Environmental Protection Agency’s (EPA’s) 2005 amendments to the federal General Pretreatment Regulation at 40 C.F.R. 403. Modifications to Article XIV, the sewer use ordinance and the enforcement response plan that incorporate the revisions to a federal rule are non-substantial changes. The department designated the city’s pretreatment program modifications as substantial because the city modified Section 25-200, where no prior local limits were established, with new local limits as maximum allowable industrial loadings for 15 national pollutants of concern after completing a detailed reevaluation of local limit analysis, which is part of this program modification. The city also updated the enforcement response plan to improve the planning procedures and guide table with additional enforcement actions for specific types of violations. The pretreatment program changes were designated substantial modifications because the changes could have a significant impact on the operation of the program, pursuant to 40 CFR 403.18(b)(7).
