    The Land Learning Foundation has requested approval for an In-Lieu Fee (ILF) mitigation project in Madison County, Missouri. The subject site consists of approximately 11.0+/- acres along the St. Francis River. The Land Learning Foundation refers to this project as the St. Francis River site, and the U.S. Army Corps of Engineers (the Corps) has designated this project as MVS-2020-742. The mitigation project includes the preservation and restoration of riparian corridor. Also, work includes bank stabilization along the St. Francis River, rock structures will be installed to direct high flows away from the unstable bank. Bank stabilization will use a combination of bank shaping, rock weirs (stream barbs), longitudinal peaked stone toe protection, brush layering, and vegetative staking. If approved by the Corps, the St. Francis River site will create a total potential mitigation credit release of 8,663.6 stream credits. The Sponsor would make the stream credits available to Department of the Army permittees seeking to fulfill requirements to purchase compensatory mitigation credit, in order to offset losses of aquatic functions and services. The Corps solicits your comments on the proposed mitigation project, responses are due to this office no later than May 14, 2021.

    Expiration date: 5/14/2021

    The Land Learning Foundation has requested approval for an In-Lieu Fee (ILF) mitigation project in Madison County, Missouri. The subject site consists of approximately 9.0+/- acres along the Castor River and an unnamed tributary. The Land Learning Foundation refers to this project as the Castor River site, and the U.S. Army Corps of Engineers (the Corps) has designated this project as MVS-2020-715. The mitigation project includes the preservation and restoration of riparian corridor. Also, work includes bank stabilization along the Castor River, reinforcement of an unstable crossing on the unnamed tributary, and grade control to prevent incising and restore riffle habitat to the unnamed tributary. Bank stabilization will use stream barbs and stone toe protection. Newberry style riffles will be used for grade control and to stabilize the stream crossing. If approved by the Corps, the Castor River site will create a total potential mitigation credit release of 6,196.75 stream credits. The Sponsor would make the stream credits available to Department of the Army permittees seeking to fulfill requirements to purchase compensatory mitigation credit, in order to offset losses of aquatic functions and services. The Corps solicits your comments on the proposed mitigation project, responses are due to this office no later than May 14, 2021.

  • National Wetland Plant List Initial

    The U.S. Army Corps of Engineers (USACE), as part of an interagency effort with the U.S. Environmental Protection Agency (EPA), the U.S. Fish and Wildlife Service (FWS) and the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS), is announcing the availability of the draft changes to the 2020 NWPL and its web address to solicit public comments. The public now has the opportunity to comment on the proposed changes to wetland indicator status ratings for five plant species in select regions and the addition of 22 new plant species to the NWPL. The Federal Register Notice (FRN) for the 2020 NWPL update can be found here: https://www.govinfo.gov/content/pkg/FR-2021-03-24/pdf/2021-05989.pdf. The public comment period ends on 24 May 2021.

  • MO 2021 NWP

    On January 13, 2021, the U.S. Army Corps of Engineers (Corps) published a final rule in the Federal Register (86 FR 2744) announcing the reissuance of 12 existing nationwide permits (NWPs) and four new NWPs, as well as the reissuance of NWP general conditions and definitions with some modifications. These 16 NWPs will go into effect on March 15, 2021, and will expire on March 14, 2026. With the publication of these NWPs in the Federal Register, the Mississippi Valley Division has finalized regional conditions for these 16 NWPs in Missouri. The Section 401 Water Quality Certifications (WQC) have been issued for Section 404 NWP activities by the Missouri Department of Natural Resources (MDNR). There are 40 existing NWPs that were not reissued or modified by the January 13, 2021 final rule. These 40 NWPs were published in the January 6, 2017, issue of the Federal Register (82 FR 1860) and these NWPs remain in effect until the Corps issues a final rule reissuing those NWPs or March 18, 2022, whichever comes first.

  • P-2731

    Expiration date: 3/25/2021

    The applicant, Holcim (US) Inc. of Ste. Genevieve, Missouri, has applied for the reverification of a Department of the Army Permit for the project known as Holcim Ste. Genevieve Harbor. The applicant seeks authorization for a reverification to continue annual maintenance dredging of accumulated river deposits with no proposed expansion or deepening of the riprap blanketed inland harbor. Holcim would continue to use a hydraulic cutterhead dredge to conduct periodic maintenance dredging on an as needed basis within Holcim’s excavated inland harbor to the original construction depth. Recent high river events have caused fine sediments to deposit within the harbor. Up to 220,000 cubic yards of accumulated sediment material would be dredged annually from within the harbor and transported in a 12-inch-diameter contained pipeline to the existing open river disposal site. The disposal pipe would exit the harbor and run southward on an existing road paralleling the riverbank. The pipeline would then angle down the existing riprap bankline into the river, where it would extend to the point of discharge near the thalwag of the river. This open river disposal site has effectively allowed for the removal of fine sediments from Holcim Harbor since the last permit renewal. At the point of discharge, the pipeline would be located on pontoons which would allow for rapid removal from the river should such action be necessary. A vessel will attend the point of discharge pipeline area at all times. The vessel would monitor radio Channel 16 at all times to remain in contact with mariners. The applicant would coordinate the activity with the U.S. Coast Guard to make notice to mariners prior to each dredging event. During discharge operations, bathymetric data would be acquired weekly to ensure the open water discharge is not negatively impacting navigation. If authorized, the permit would be valid for a five-year period. The Public Notice comment period opens March 4, 2021 and closes March 25, 2021.

Thumbs up for safety!
