Who must prepare planning materials for an OSSF that utilizes secondary treatment?

The requirement for planning materials for an On-Site Sewage Facility (OSSF) that utilizes secondary treatment is specifically designated for individuals who possess the appropriate technical expertise and credentials. In this case, a Professional Engineer (PE) or a Registered Sanitarian (RS) must prepare these materials.

A PE or RS is trained and certified to understand the complexities of wastewater treatment systems, including the intricacies involved in secondary treatment, which is essential for ensuring the design and implementation align with health, safety, and environmental standards. These professionals have the requisite knowledge to evaluate site conditions, design systems that meet regulatory requirements, and anticipate potential issues related to wastewater management.

The other roles, such as environmental technicians, site managers, or government inspectors, do not hold the same level of authority or technical acumen required for such planning tasks. While they may play important roles in the broader context of OSSF management, they lack the specific qualifications needed to prepare the detailed and technical planning materials mandated for secondary treatment systems.
