According to the CDPHE's pre-abatement sequence, what is the first action that needs to be taken?

The first action in the CDPHE's pre-abatement sequence is to prepare a project plan. This step is crucial because it lays the foundation for the entire abatement project, outlining the scope, objectives, and methodologies to be employed during the process. This planning phase addresses the specific aspects of the abatement work, the required resources, timeline, and necessary safety measures.

In developing a project plan, all participants can align on the expected outcomes and procedures, which ultimately leads to a more organized and effective abatement process. Being thorough in this initial phase helps in identifying potential risks, compliance requirements, and environmental considerations, which are critical for a successful project.

Subsequent actions, such as installing critical barriers, notifying local authorities, or conducting air quality testing, can only be effectively implemented once there is a clear and detailed plan in place to guide those actions.
