What was a significant outcome of the Urban Runoff Program?

The Urban Runoff Program primarily aimed to address the challenges and impacts of urban runoff on water quality. A significant outcome of this program was conducting studies on the effects of stormwater runoff and the various control measures that can be implemented to mitigate these impacts. This involved research into how urbanization contributes to runoff pollution and the development of best management practices (BMPs) to treat or manage the runoff effectively.

The program focused on understanding the relationship between urban development and water quality, which led to improvements in stormwater management policies. By studying different control measures, the program provided valuable insights that can help municipalities develop more sustainable and effective strategies for handling stormwater.

The other options relate to different aspects of environmental regulation but do not capture the central goal and achievement of the Urban Runoff Program as accurately. The mandate for nationwide stormwater permits and establishing regulations for hazardous waste management are broader regulatory frameworks not specific to urban runoff. The creation of a framework for pollutant tracking, while important, is more of a systematic tool rather than a direct focus of the Urban Runoff Program's studies on impacts and control measures.
