What are the recognizable elements of a FOIA request letter?

The FOIA specifies two requirements for a request:

  1. the request must "reasonably describe" the records sought, and
  2. the request must be made in accordance with DOL’s published FOIA regulations (see https://arlweb.msha.gov/readroom/2006004885.pdf )
