Since 12VAC5-615 did not get repealed, look at pulling the Standard of Practice section into the AOSS regulations.
I know that this would be required to change / amend 12VAC5-610, but look at requiring a license number be required on ALL completion statements from AOSE and Installers and require a license number for issuance of a Sewage Handling Permit to prove that the company can in fact pump a COSS and an AOSS!
