Where must the notice of coverage letter be posted according to regulations?

The notice of coverage letter must be posted near the main entrance of the construction site and included in the general information section of the Storm Water Pollution Prevention Plan (SWPPP) because this ensures that it is easily visible to both workers and the public. This visibility is crucial as it informs everyone entering the site about the stormwater management practices that are in place, which promote transparency and compliance with regulations.

Posting the notice in these locations helps raise awareness among those on the site — including workers, regulators, and visitors — about the stormwater permitting and mitigation measures being employed. Including it in the SWPPP also makes it part of the comprehensive documentation required to demonstrate compliance with environmental regulations. Furthermore, this practice supports proactive site management, ensuring that all personnel are informed about the necessary measures to prevent stormwater contamination.

Other options, like placing it solely in the project manager's office or only in the site files, would not achieve the same level of visibility and accessibility. Additionally, while posting on a company website might be useful for public information, it does not meet the regulatory requirement to make the notice readily available at the physical site.
