Which of the following is NOT a step in developing an effective SWPPP?

An effective Stormwater Pollution Prevention Plan (SWPPP) is vital for managing runoff and ensuring compliance with environmental regulations. The development of an SWPPP involves several key steps that help identify potential sources of pollution and establish best management practices.

Ignoring regulations is not a step in the development process, as it goes against the fundamental purpose of a SWPPP, which is to comply with local, state, and federal laws. Regulations are in place to protect water quality and, as such, any effective SWPPP must account for and adhere to them.

In contrast, implementing the plan, evaluating data, and collecting data are all integral steps in creating a responsive and adaptive SWPPP. Implementing the plan involves putting the strategies and practices into action, while evaluating data allows for ongoing assessment and improvement of the SWPPP's effectiveness. Collecting data is essential for understanding the site's specific conditions and identifying potential pollution sources, thereby ensuring the plan addresses relevant issues. Thus, those three processes are critical components of an effective SWPPP.
