i. All indoor above ground tank systems
				shall have the capacity to contain 100% of the volume of the largest above
				ground tank;
ii. All outdoor
				aboveground tanks systems shall have the capacity to contain either 10% of the
				total possible contained volume of the aboveground tanks, or 110% of the volume
				of the largest aboveground tank, whichever is greater.
b. A generator shall remove all accumulated
				spillage and/or precipitation from the containment area within 24 hours or in
				as timely a manner as possible.

				inspection or until final closure pursuant to 310 CMR 30.343(1)(i), whichever
				period is longer. These records shall be furnished to the Department upon
				request.
3. At a minimum, these
				records shall include the date and time of the inspection, the name of the
				inspector, a notation of the observations made, and the date and nature of any
				repairs or other remedial actions.
4. All aboveground tanks shall be placed so
				that all the surface beneath each such tank can be inspected for spills and
				structural integrity.
