An antidegradation review request was submitted by Connie M. Walden, P.E. of Great River Engineering for the Missouri Department of Conservation - Lost Valley Fish Hatchery to evaluate expansion and limits of a recently permitted wastewater treatment system supporting the production of 147,000 pounds of fish annually. As a newly permitted discharging system a water quality and antidegradation review is required. The treatment system is a batch process which treats a total design flow of 7.32 million gallons per day (MGD) with an estimated average daily flow of 3.46 MGD.
The department proposes to make a preliminary antidegradation determination for project, subject to certain effluent limitations, schedules and special conditions. The department invites the public to review and offer written comments on the proposed permit conditions until Jan. 6, 2025. All comments must be received or postmarked by 5 p.m. The public can review the proposed preliminary determinations 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: Engineering Section/ Antidegradation Comments, PO Box 176, Jefferson City, MO 65102-0176 or by email to DNR.WPPEngineerSection@dnr.mo.gov. Please identify the project in all comment letters. The department can only consider comments about issues relating to the preliminary determination and its effect on water quality. The department cannot consider comments or objections to a preliminary determination based on issues outside the authority of the Missouri Clean Water Commission (see Curdt v. Mo. Clean Water Commission, 586 S.W.2d 58 Mo. App. 1979).
The proposed project is consistent with the "Missouri Antidegradation Implementation Procedure" and meets the applicable requirements. The proposed preliminary determinations are tentative pending public comment. If response to this notice indicates there is significant public interest, the department may hold a public meeting or public hearing, after due public notice. Public hearings and finalizing determinations are conducted or processed according to 10 CSR 20-6.020.
