There is more to context than just words... Please notice the excellent use of punctuation in this sample text. I do not believe this term could be “among others” simply because if it was, there should be at least another comma, (I would use two). It is, of course, possible that the author “missed” placing the commas there, but judging from the rest of the punctuation, I think it is highly unlikely.

a.o. Administrative Order:
A legal document signed by EPA directing an individual, business, or other entity to take corrective action or refrain from an activity. It describes the violations and actions to be taken, and can be enforced in court. Such orders may be issued, for example, as a result of an administrative complaint whereby the respondent is ordered to pay a penalty for violations of a statute. http://www.caslab.com/Administrative_Order_Meaning/
