(a) After FRA has approved a railroad's certification program, a railroad shall not permit or require a person to serve as a dispatcher on a particular territory unless that railroad determines that:

(1) The person is a certified dispatcher; and

(2) The person either:

(i) Possesses the necessary territorial qualifications for the applicable territory pursuant to § 245.119; or

(ii) Is assisted by a Dispatcher Pilot who is qualified on the territory.

(b) If a person is called to serve on a territory that they are not qualified on, the person must immediately notify the railroad that they are not qualified on the assigned territory.

(c) A person shall no longer be considered qualified on a territory if they have not worked on that territory as a dispatcher in the previous 12 months.

(d) Each railroad shall adopt and comply with a program meeting the requirements of this section. When any person (including, but not limited to, each railroad, railroad officer, supervisor, and employee) violates any requirement of a program which complies with the requirements of this section, that person shall be considered to have violated the requirements of this section.
