The construction program, as well as specific characteristics of project design, should incorporate Best Management Practices (BMPs) to reduce erosion, minimize sedimentation, control non-stormwater discharges, and protect the quality of surface water features potentially affected. BMPs are defined as nonstructural and structural practices that provide the most efficient and practical means of reducing or preventing pollution of stormwater. The selection of these practices at San Marcos Municipal Airport should be based on the site's characteristics and focus on those categories of erosion factors within the contractor's control, including: (1) construction scheduling, (2) limiting exposed areas, (3) runoff velocity reduction, (4) sediment trapping, and (5) good housekeeping practices. Inspections of the construction site and associated reporting may be required. The construction activities associated with airport development may require a permit issued under Section 404 of the Clean Water Act. A 404 permit would be required for the discharge of dredged or fill material into the waters ofthe United States, including adjacent wetlands. Ajurisdictional devneation (completed by the Corps of Engineers) is required to determine if a permit is required. Prior to any construction activities, the City of San Marcos should obtain a jurisdictional delineation of wetlands and waters of the U.S. from the Corps of Engineers. Spills, leaks and other releases of hazardous substances into the local environment are often a concern at airports due to fuel storage, fueling activities and maintenance of aircraft. Stormwater flowing over impermeable surfaces may pick up petroleum product residues and, if not controlled, transport them off site. Also of crucial concern would be spills or leaks of substances that could filter through the soils and contaminate groundwater resources. As growth in aviation activity occurs, additional fuel storage facilities will be necessary. Fuel storage facilities must be designed, constructed and maintained in compliance with Federal, State and local regulations, and must be registered with TNRCC. These regulations include standards for underground storage tank construction materials, the installation of leak or spill detection devices, and regulations for stormwater discharge. The airport currently has two above ground fuel storage facilities which meet all state and federal requirements. DEPARTMENT OF TRANSPORTATION ACT, SECTION 4(F) LANDS Paragraph 47e, FAA Order 5050.4A provides the following.
