When the job is completed is there any form of certification that it has been done and that it meets Title 5 standards?

At the completion of the job, (that is, when all work has been done according to the plans; all required inspections have been done by the Health Agent; when the engineer has submitted an “as-built” plan as to where the system was installed; and when the installer has submitted a certification statement), the Health Agent signs a Certificate of Compliance, (COC), which is issued to the installer. Upon payment for the work, the installer gives the COC to the homeowner.
