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.
The age at which there are no restrictions for sexual activities is 18, while the minimum age of consent is 13 regardless of gender and/or sexual orientation. For those 13-16, restrictions include abuse, violence, threat, coercion, or harassment in a relationship of dependence, authority or power, or by taking advantage of the fact that the minor, for any reason, couldnât freely give consent.
