Good idea to document determination. - Particularly if you conclude you are not subject to the rule. - Not a rule requirement. See Section 2.4 of SPCC guidance document. http://www.epa.gov/emergencies/docs/oil/spcc/guidance/2_Applicability.pdf.
The age of consent is eighteen. With parental consent, parties can marry at age seventeen with the exception that if one party does not have a parent who resides in the state and one party has been a resident in Oregon for at least six months, then no permission is necessary.
In Europe, countries who have the age of consent set at 16 include Cyprus, Finland, Georgia, Latvia, Lithuania, Luxembourg, the Netherlands, Norway, and Switzerland. For Austria, Germany, Portugal and Italy it is 14, and in France, the Czech Republic, Denmark, and Greece it is 15.
