The seal assembly further includes an attachment plate for attachment to the tank surface and adapted to be disposed about the tank opening. The seal assembly includes at least one attachment fastener cooperating with the attachment plate to secure the access cover to the attachment plate and to seal the tank opening via the first seal and the second seal.
