What is one of the requirements for gathering documentation for water quality compliance in the SWM plan?

Gathering discharge information is crucial for documenting water quality compliance in a Stormwater Management (SWM) plan because it provides specific data on the volume and quality of water being released from a site. This information is essential for evaluating how stormwater runoff is managed and its impact on local water bodies. Understanding how much water is discharged and what pollutants it may contain allows inspectors to assess whether the SWM practices are effectively minimizing negative effects on water quality.

Monitoring discharge helps ensure that the facility adheres to regulatory water quality standards and permits. By documenting this information, professionals can better determine if the stormwater management strategies in place are adequate and if adjustments are necessary to protect water resources.

Gathering hydrologic models, contingency planning documents, or environmental impact assessments are important in other contexts but do not specifically focus on the immediate compliance with water quality as directly as discharge information does.
