Which of the following BMPs would typically NOT be marked on site maps?

The reasoning behind this choice lies in the purpose and content of site maps as used in stormwater pollution prevention planning. Site maps are primarily used to identify physical features and structures related to stormwater management and pollution prevention techniques on a location. These features typically include the geographical layout, drainage systems, and best management practices (BMPs) that are installed to mitigate environmental impacts.

Personnel training schedules, while an essential part of compliance and operational effectiveness, do not pertain to physical features or infrastructure that would be represented on a map. The scheduling of training is more administrative in nature and focuses on human resources, whereas site maps are meant to provide a visual representation of the physical aspects of the site. Consequently, items such as weather-related changes, dates of BMP modifications, and installed drainage systems are relevant for assessing and managing stormwater impacts and would be included on these maps, whereas training schedules would not.
