Which is not a component required in cleanup reports?

In cleanup reports, it's essential to include various components that ensure thorough documentation and accountability. A critical aspect of these reports is the inclusion of a site map, which provides a visual representation of the area affected and helps in assessing the extent of contamination. Additionally, detailing the name of the service provider involved in the cleanup process establishes responsibility and accountability, allowing for verification of the work performed.

Furthermore, including the name and signature of the report preparer is vital, as it indicates who was responsible for compiling and submitting the report, which is important for clarity and potential follow-up.

While estimating cleanup costs is a relevant aspect of any project involving environmental remediation, it is not always a mandatory component of cleanup reports. This allows the focus to remain primarily on the actions taken and the current status of the site rather than financial details. Thus, the option regarding the estimated cleanup cost is correctly identified as not being a required component of cleanup reports.
