22-3 Water

Storage

Under the water plan, is it correct that Onsite water storage tank increased from 1,000,000 gallons (1 MG) to 2.25 MG? That is a 125% size increase, which in all likelihood, increases the footprint of impervious at the site. Please explain.


RESPONSE 22-3

No, the original application consisted of an approximately 1,000,000 gallon tank for demineralized water and an approximately 800,000 gallon tank for service water/fire water.

The revised configuration consists of an approximately 1,850,000 gallon tank for demineralized water and an approximately 1,050,000 gallon tank for service water/fire water.

This revised volume does not increase the footprint or affect the imperious coverage at the site. The volume increase is achieved by increasing the height of the tank. The diameter of the demineralized water tank was previously stated as 110 feet in diameter and 30 feet tall and is now revised to approximately 85 feet in diameter and 55 feet tall. The height of the service water/fire water tank has been increased from 30 to 49 feet.
