What must be marked on Site Maps in the job site trailer as construction progresses?

Marking the dates when Best Management Practices (BMP) changes or additions take place on the Site Maps in the job site trailer is crucial for several reasons. Firstly, it ensures proper documentation of the stormwater management practices implemented at various stages of the construction process. This documentation is essential for compliance with environmental regulations and in case inspections are conducted by regulatory bodies.

Additionally, having dated records of BMP modifications allows for a clear understanding of what practices were in place at any given moment and how they evolved, which can be vital for assessing their effectiveness in preventing stormwater pollution. It also aids in training new staff and maintaining consistency in BMP implementation throughout the life of the project.

In contrast, while knowing the names of all workers, inspection dates, and weather conditions are important for project management and compliance, these details are not as directly related to the ongoing modifications and effectiveness of stormwater management practices on the job site. Thus, marking the specific changes and their dates provides the most critical info needed for effective stormwater pollution prevention efforts.
