There a couple of way to create access schemes. One is outlined in the comment to this page (thanks: johnmunro). Another one is to equate a "scheme" to a role and then proceed as follows. Select the “department” vocabulary, set the number of schemes to 4 and press “Save configuration”. Now click Scheme 1 (name it “sports author”) to assign view and update grants associated with the “sports” term to the Sports Author only. Then using Scheme 2 (“arts author) do the same for the “arts” term in relation to the Arts Author. Keeping things simple for now, use Scheme 3 to grant view, update and delete (if desired) access for all terms to the Moderator role. You may refine this later with more moderators. Finally, if the departmental content is to be viewed by the public, then use Scheme 4 (“public”) to grant view access only for all terms to anonymous users only. Do not include "authenticated users" in the "public" scheme as this will result in authors being able to create content for departments they don't belong to. Save.</p>
