The Alaska Stormwater Control Ordinance (ASCOT) is a set of regulations and requirements implemented by the state of Alaska to effectively manage and control stormwater runoff within its municipalities and communities. The ASCOT aims to protect the state's water resources, prevent flooding, and preserve water quality by addressing the detrimental effects of stormwater runoff. Under the ASCOT, various types of stormwater control ordinances have been established, each targeting specific aspects of stormwater management. These ordinances include: 1. Construction Stormwater Control Ordinance: This ordinance focuses on controlling the potential pollution caused by stormwater runoff during construction activities. It requires construction projects to implement erosion and sediment controls, as well as the best management practices (BMPs) to minimize the discharge of pollutants into nearby water bodies. 2. Post-Construction Stormwater Control Ordinance: This ordinance regulates stormwater management practices after the completion of construction projects. It aims to control the impact of developed areas, such as paved surfaces, roofs, and parking lots, on stormwater runoff. The ordinance ensures the implementation of structural controls, such as detention ponds, rain gardens, and permeable pavement, to control and treat stormwater runoff effectively. 3. Illicit Discharge Detection and Elimination Ordinance: This ordinance aims to prevent the unauthorized discharge of pollutants into stormwater drainage systems. It requires inspections, monitoring, and enforcement measures to identify and eliminate illicit discharges, such as dumping of chemicals or wastewater into storm drains. 4. Pollution Prevention/Good Housekeeping Ordinance: This ordinance targets municipal operations and activities that can contribute to stormwater pollution. It requires municipalities to implement practices and measures to prevent pollution from activities, such as street sweeping, landscaping, fleet maintenance, and waste management. The ASCOT mandates compliance with these ordinances to ensure that stormwater runoff is appropriately managed to protect Alaska's water resources and maintain environmental sustainability. It emphasizes the use of BMPs, erosion controls, and treatment practices minimizing pollution and maintain high water quality standards in the state.
