Requests for Commission staff to conduct a CNG training class for CNG activities under the Commission's jurisdiction shall be submitted to the AFS training section. The AFS training section may conduct the requested class at its discretion. The nonrefundable fee for a CNG training class is $250 if no overnight expenses are incurred by the AFS training section, or $500 if overnight expenses are incurred. AFS may waive the class fee in cases where the Commission recovers the cost of the class from another source, such as a grant.
