Section 5

Amends the directives relating to the implementation of 15 NCAC 18E .0206 (Existing System Approvals for Recommendations and Property Additions), deeming the owner (rather than the "applicant") responsible for providing property lines and modifications, locating the existing wastewater system and providing that information to the specified entity or professional, as applicable, ensuring the accuracy of the information provided in the application, and ensuring that all setback requirements under rule .600, Subchapter E, 15A NCAC 18 are met for the addition.

Section 6

Amends the directives relating to the implementation of 15A NCAC 18E .0207 (Alternative Wastewater System Permitting Options). For systems issued an engineer option permit, allows the engineer to use pretreatment technologies (previously, technologies generally) not approved in the State provided the attached report to the authorization specifies the technology and the manufacturer's approval for the site conditions.

Section 15

Amends the directives relating to 15A NCAC 18E .0805 (Tank Leak Testing and Installation Requirements), more specifically requiring that for a hydrostatic test, the tanks for corrugated tanks must be filled to the bottom of the uppermost corrugation that forms the top of the tank.
