What is the maximum time frame to develop written procedures for visual assessments after a storm water permit is issued?

The maximum time frame to develop written procedures for visual assessments after a storm water permit is issued is six months. This requirement is part of the regulations designed to ensure that facilities take timely action to manage stormwater runoff, which can have significant environmental impacts.

Having a six-month period allows facilities to create comprehensive procedures that adequately address the specific needs of their operations and the potential impacts on stormwater quality. This timeline emphasizes the importance of prompt action to comply with permit conditions, ensuring that visual assessments are established early on to monitor and reduce pollutant discharges.

This period is essential for operators to develop thorough, effective procedures and ensures that they are in place as soon as possible, aligning with best management practices and regulatory compliance.
