The actual first steps for a records request, a utility complaint, or finding your elected officials.
If the 20-business-day window passes with no response, you're entitled to treat that as a constructive denial and can appeal to the agency's FOIA appeals office, then ultimately sue in federal district court — though most disputes resolve well before that stage.
