A marina almost always has two entirely separate wastewater questions: boat sewage pump-out, which sits in a regulatory track connected to the federal Clean Vessel Act pump-out program, and any onsite system serving the marina's own restrooms, office or restaurant, which is designed and permitted like any other commercial building.
Pump-out stations that remove sewage from boat holding tanks are a distinct waste stream from anything generated inside the marina's buildings, and in many states that pump-out infrastructure connects to programs tied to the federal Clean Vessel Act, which has funded pump-out facilities specifically to keep boat sewage out of the water. That is a separate regulatory question from whether the marina office, restrooms, ship's store or any on-site restaurant has an adequate onsite wastewater system.
Fuel and oil handling at a marina is also regulated separately again, through oil-water separation and spill-prevention rules that have nothing to do with sanitary wastewater design.
Once boat pump-out and fuel handling are set aside, the marina's own buildings are sized the ordinary commercial way: fixture counts and expected occupant or customer load for restrooms, plus a food-service calculation if there is a restaurant or snack bar on site.

A new use, an addition, a remodel, a change of tenant, gets compared against what a commercial property is already permitted for. Where a recorded septic file exists for the property, it typically shows the tank size, the treatment components, the drainfield or dispersal area, and the design flow the system was approved for, which is the starting point for figuring out whether a change fits inside the existing approval or needs an upgrade. We publish where county septic records are kept and how many we hold, we list local septic companies by county, and we generate a free, code-referenced septic design for a parcel to use as a starting point.

No. Pump-out removes sewage from boat holding tanks and sits in a separate regulatory track, often connected to the federal Clean Vessel Act program, distinct from any onsite system serving the marina's buildings.
Yes, the same as any other food-service operation; a snack bar or restaurant at a marina is sized and regulated as food service, separately from the boat pump-out question.
No, that is handled through separate oil-water separation and spill-prevention rules unrelated to sanitary wastewater design.
