text: Well, if you want blueprints, you can always go to your local municipal development services office and ask to se them.  They may charge you a few bucks for photocopies but they are essentially public record.  They require no identification or clearance to see and all you have to do is know what you are looking at.  \n\nI used to work in one of those departments.  The blueprints are used to approve construction permits.  Since construction permits are official documents approving development work, they are therefore subject to complete public scrutiny at any time.  They legally cannot prohibit you from making a copy.  \n\nWhen I issued fuel station permits, we had multiple levels of protocols for environmental impact, groundwater protection, surface water runoff, explosion prevention, hazardous materials, fire, etc...  Each of these areas were checked off and cleared by municipal authorities.  While Shell may have standards that they follow, they ultimately must get approval from the local government to build and this approval comes with conformity to either a local, state, or regional standards body.  \n\nHope this helps!
