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 legal age of consent in the United States varies from state to state, with different ages applicable based on a variety of factors including the genders of the actors, type of sexual act, relationship between the actors, and more. The age of consent is between 16 and 18 in all states. Violation of these laws by engaging in sexual acts with a person under the applicable age of consent can result in charges from a misdemeanor (such as corruption of a minor) to a felony (such as statutory rape) depending on the jurisdiction and the circumstances.
