I found USCG regs for securing portable fuel tanks, but nothing from them or ABYC about securing permanent installed fuel or waste tanks. Nor, in all the years I've been in marine sanitation have I ever heard of any standards or regs for installing waste tanks other than a USCG reg that requires black and gray water holding to be totally separate systems...separate tanks and no common plumbing, not even a tank vent.

It would indeed be helpful to know what type of tank the OP is installing.
