Is there a fund to cleanup contaminated sites?
Yes. See “Cleanup Program” for more information. 17. Secondary Containment All aboveground storage tanks require secondary containment to contain accidental spillage. There are two ways of attaining secondary containment on aboveground storage tanks. Single wall tanks are placed in a conventional dike system to contain accidental spillage where the walls and base are made of non-combustible material providing a permeability of not more than 10-6 cm/sec. The capacity of the secondary containment area is important. If there is only one tank the dike must be capable of containing 110% of the capacity of the tank. If there is more than one tank the volumetric capacity of the dike must be the capacity of the largest tank plus 10% of the capacity of the largest tank or 10% of the aggregate of the remaining tanks, whichever is greater. Dike walls must be no less than 1.5 meters from any tank shell. The second type of aboveground tank secondary containment is of the double walled variety or co
