What is the consequence of failing to renew a septic installer certification?

When a septic installer certification is not renewed, it becomes invalid, meaning the individual is no longer legally authorized to perform septic installation work. Certification serves as proof that the installer has met the necessary training and competency requirements to ensure the safe and effective installation of septic systems, which is critical for public health and environmental protection. Once the certification lapses, the individual cannot undertake any septic system installations until they renew their certification, effectively halting their ability to work in that capacity legally.

The other options involve consequences that do not directly result from the failure to renew the certification. While increased training requirements or fines could be related to other aspects of compliance, they do not specifically address the immediate impact of an expired certification. The loss of a business license could happen in some situations, but it is not a direct result of the failure to renew the certification itself.
