Identifying these sources enables targeted controls—such as designated washout areas and spill containment systems—to protect downstream water bodies.

What Are Stormwater Pollution Prevention Plans (SWPPP) and Their Role?

A Stormwater Pollution Prevention Plan (SWPPP) is a documented strategy outlining site-specific controls to minimize stormwater contaminants. It includes site maps, BMP descriptions, inspection schedules, and maintenance procedures. Regulatory agencies require SWPPPs under Kentucky’s General Permits for Discharges, ensuring sites implement best practices for sediment control, slip-lined channels, and post-storm evaluations. SWPPPs facilitate compliance and demonstrate proactive environmental management.

Assessment of Water Quality and Sediment Erosion for Fort Knox Construction

New training facilities have been proposed for construction at the Fort Knox Northern Training Complex. These facilities include a digital training range and a complex of droplanding zones and a manoeuvre area. During the review of an Environmental Assessment, concerns were raised regarding sediment erosion and adverse water quality impacts arising from the construction and project. Assessments of existing water quality data and the potential for sediment erosion were conducted to address potential impacts. Water quality data collected between 1995 and 1998 near the study area at the two major rivers, onsite data collected for discharge permit monitoring, data retrieved from the U.S. Environmental Protection Agency’s Storage and Retrieval system (STORET), and real-time discharge data were available for assessing existing conditions. Material loading was estimated using water quality and discharge data. Sediment yield for pre-project and post-project conditions for each alternative was conducted using the Revised Universal Soil Loss Equation, soil characteristics, and terrain slope developed from digital terrain elevation data. Water quality constituents generally fell within acceptable concentration ranges, although total phosphorus concentrations were well above concentration guidelines used for lakes and reservoirs (0.02 mg L⁻¹), and elevated concentrations of solids, nutrients, and faecal coliform were most commonly observed with runoff events. Loading estimates indicated that sediment loads in the Salt River were approximately four times higher than in the Rolling Fork River.
