What critical element must be included in the permit for an HTSS?

The critical element that must be included in the permit for an HTSS (Holding Tank Sewage System) is the specific requirements for pumping service frequency. This aspect is essential because it ensures that the tank is maintained effectively and does not overflow or lead to environmental contamination. The permit outlines how often the tank must be pumped out to manage the sewage properly, considering factors such as tank size, usage rates, and local regulations.

Incorporating this information helps to protect public health and the environment by preventing the release of untreated sewage. Regular pumping as specified in the permit is crucial for the proper operation of the holding tank and to comply with health and safety standards.
