When monitoring detects exceedances of statutory or permit limits, the appropriate response is to record the event, investigate, take corrective action, and report the exceedance as required by law/permit conditions. NPPE content stresses legal compliance, transparency with regulators, and proper documentation. Option B reflects this: emissions exceedances must be logged and reported through the prescribed channels (which may include immediate notification and follow-up reporting), along with steps taken to mitigate impacts and prevent recurrence. Option A may be appropriate only if the sensors are proven faulty; it is not the default response to a confirmed exceedance. Option C is improper because it encourages ignoring non-compliance; exceedances are not excused by being “first occurrences.” Option D misunderstands regulation—companies cannot simply request lower statutory thresholds to avoid non-compliance, and authorities do not adjust public-protection limits on that basis. Therefore, B is correct.
