Which of the following is a requirement for storage tank venting as per TCEQ regulations?

The requirement for storage tank venting according to TCEQ regulations emphasizes the need for covered vents with an airtight design to prevent any potential leaks or the escape of vapors from the tank. This design helps maintain the integrity of the tank's contents, minimizes the risk of pollution, and enhances safety by controlling pressure and ensuring proper atmospheric conditions within the tank. Airtight venting prevents contaminants from entering the tank and stops harmful vapors from escaping into the environment, aligning with regulatory efforts to protect public health and the environment.

Other options do not meet the stringent safety measures outlined in TCEQ regulations. Uncovered vents can lead to unregulated airflow, allowing for contamination and vapor release. Covered vents with filters may still allow smaller particles or vapors to escape, thus failing to provide complete protection. The notion that any type of vent is acceptable disregards the crucial need for strict controls aimed at ensuring environmental safety and tank integrity. Therefore, the requirement for covered vents with an airtight design is a critical aspect of compliance with TCEQ regulations.
