Area of Focus: Water
Event Type: Public Notice/ Public Comment
Organization: Water Protection Program

The city of Moberly currently has an approved pretreatment program to meet the requirements of the Clean Water Law. The city of Moberly 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 Feb. 7 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 to adopt the U.S. Environmental Protection Agency’s 2005 amendments to the federal General Pretreatment Regulation at 40 CFR 403. Modifications to the sewer use ordinance and enforcement response plan that incorporate the revisions to a federal rule are non-substantial changes, as stated in 40 CFR 403.18(b)(1). However, the city’s pretreatment program changes were designated substantial modifications because of the following changes:

  1. The city modified Section 42-416(b)(2), pH, to a less restrictive standard unit range,
  2. The city modified its sewer use ordinance to remove local limits that inappropriately referenced the 40 CFR 433 Metal Finishing Categorical Standards and
  3. The city eliminated portions of the sewer use ordinance that were covered in other sections.

The detailed reevaluation of local limit analysis is not part of this program modification, and the city plans that for a later modification. The city, additionally, updated the enforcement response plan to improve the planning procedures and guide table with additional enforcement actions for specific types of violations. These changes could have a significant impact on the operation of the program, pursuant to 40 CFR 403.18(b)(7).
