The applicant, Mid-America St. Louis Airport (BLV), requests authorization under Section 404 of the Clean Water Act to convert 62.91-acres of forested wetland to emergent wetland and complete grading and filling within 8.23-acre of wetlands to construct a permanent service route along the runways.
As part of the 2021 BLV Master Plan Update, Forest Management Plan, an obstruction survey was conducted at BLV, resulting in approximately 129 acres of trees within three areas (known as Phases 1, 2, and 3) being identified as existing and future obstructions to various airspace protection zones, including Federal Aviation Regulation (FAR) Part 77 Surfaces; Federal Aviation Administration (FAA) Airports Approach/Departure Surfaces; FAA Order 8260.3F, The United States Standard for Terminal Instrument Procedures (TERPS) Surfaces; and Airport Traffic Control Tower Line of Sight. Any man-made or natural object that penetrates these surfaces must be removed to prevent adverse effects on these zones. The Project to be completed will protect the airspace around the BLV and improve the safety of BLV approaches and operations through the removal of existing and future tree obstructions to the BLV runway and the SAFB runway and the construction of a permanent service route to facilitate the tree removal and future maintenance. The Project is located within the Silver Creek floodplain east of the BLV terminal located at 9656 Air Terminal Drive, Mascoutah, St. Clair County, Illinois. Approximate geographic coordinates for the Project are Latitude 38.5540° and Longitude -89.8294°.
