Reasonable open periods. This part does not specify hours, days and seasons, 
however, some suggested examples, provided no other factors are involved, are 
presented:

(1) Pumpout/dump stations may be open during the same period the fuel docks are 
normally open.

(2) Pumpout stations may be open when the marina is open and staff is present to 
pump out boats.

(3) Pumpout/dump stations may be open during the hours considered to be normal 
marina business hours as adjusted by seasonal differences.
