According to TCEQ regulations, what must storage tanks have?

According to TCEQ regulations, storage tanks must have covered vents and an airtight cover to prevent contamination and control emissions. This requirement is crucial for maintaining the quality of the water stored within the tanks and preventing the introduction of airborne pollutants or debris. Covered vents ensure that vapors do not escape into the atmosphere, which can be especially important for tanks containing volatile substances. An airtight cover also minimizes the risk of contamination from external sources, such as rainwater or dust.

The absence of these features could lead to environmental pollution and contamination of the water supply, which is why they are emphasized in regulatory guidelines. This requirement helps in creating a safer and more reliable storage system, which is essential for the proper management of water resources.
