What kind of permits are required for installing new OSSFs?

To install new On-Site Sewage Facilities (OSSFs), a permit must be obtained from either the Texas Commission on Environmental Quality (TCEQ) or the local regulatory authority designated to oversee such installations. This requirement ensures that the systems adhere to environmental regulations and public health standards.

Having this permit is crucial as it establishes that the installation meets safety, environmental, and technical standards necessary to manage sewage effectively. Regulatory authorities ensure compliance with state and local codes, which address factors such as soil characteristics, system design, and maintenance to protect water quality and public health.

The other options do not align with the regulatory framework governing OSSFs. While it might seem feasible to consider self-installation without a permit or assume that only state oversight is necessary, the coordinated approach between state and local authorities is integral to environmental protection. Similarly, requiring a federal permit for all installations is not applicable, as OSSFs typically fall under state and local jurisdiction unless they involve federal oversight for specific cases.
