At any time as the board may specify in a written notice, but in no case more than three times in a calendar year, the board may require a person making sales to operators of catering trucks to submit to the board a listing of operators of catering trucks who purchase goods from that person. Each listing shall be provided to the board within 30 days after the date of the board's notice, and shall include the name and seller's permit number on file of each operator, or, for those operators who do not provide evidence of a valid seller's permit, the operator's name, address, and telephone number.
The board may also, by written notice, require a person making sales to operators of catering trucks to promptly notify the board if a newly purchasing operator does not provide to the person, within 30 days of the date of the first purchase, evidence of a valid seller's permit.
Persons required by written notice of the board to obtain evidence, or provide a listing or notification, who fail to comply, may be subject to a penalty not to exceed five hundred dollars ($500) for each failure.
Any person seeking to be relieved of the penalty shall file with the board a statement under penalty of perjury setting forth the facts upon which he or she bases his or her claim for relief.
