A company has installed sensors to monitor emissions from a stack. If the company discovers that the stack emissions on a particular day exceed…

When monitoring equipment indicates an exceedance of statutory (legal) levels, the company has a legal and ethical obligation to act. The first step is to treat the data as valid, record the details of the occurrence for due diligence purposes, and report the exceedance to the appropriate environmental regulatory body as required by law. This demonstrates compliance with environmental legislation and the professional duty to protect the public and the environment. Failure to report can result in significant fines and legal penalties for both the company and the individuals involved.

A. Replacing the sensors without investigation is an assumption of equipment failure. The primary duty is to address the potential environmental and legal violation indicated by the data.

C. Discounting or ignoring valid data is unprofessional, negligent, and a violation of the principle of due diligence. It could lead to ongoing environmental harm.

D. Applying to lower statutory levels is not a valid response to non-compliance. Environmental standards are set to protect the public and are not negotiable on a case-by-case basis.
