CA Rev & Tax Code Section 60603


Officers or employees of the state, upon presenting appropriate credentials and a written notice to the owner, operator, or agent in charge, are authorized to enter any place and to conduct inspections in accordance with paragraphs (1) to (6), inclusive.


Inspections shall be performed in a reasonable manner and at times that are reasonable under the circumstances, taking into consideration the normal business hours of the place to be entered.


Inspections may be at any place at which taxable diesel fuel is or may be produced or stored or at any inspection site where evidence of activities involving evasion may be discovered. These places may include, but are not limited to, any terminal, any diesel fuel storage facility that is not a terminal, any retail diesel fuel facility, or any designated inspection site.


A designated inspection site is any state highway inspection station, weigh station, agricultural inspection station, mobile station, or other location designated by the state or the Internal Revenue Service to be used as a diesel fuel inspection site. A designated inspection site shall be identified as a diesel fuel inspection site.


Officers or employees may physically inspect, examine, or otherwise search any tank, reservoir, or other container that can or may be used for the production, storage, or transportation of diesel fuel, diesel fuel dyes, or diesel fuel markers. Inspection may also be made of any equipment used for, or in connection with, production, storage, or transportation of diesel fuel, diesel fuel dyes, or diesel fuel markers. This includes any equipment used for the dyeing or marking of diesel fuel. This includes the books and records kept to determine tax liability.


Officers or employees may detain any vehicle, train, or vessel for the purpose of inspecting its fuel tanks and storage tanks. Detainment will be either on the premises under inspection or at a designated inspection site. Detainment may continue for a reasonable period of time as is necessary to determine the amount and composition of the diesel fuel.


Officers or employees may take and remove samples of diesel fuel in reasonable quantities as necessary to determine its composition.


Any person that refuses to allow an inspection may be fined one thousand dollars ($1,000) for each refusal. This penalty is in addition to any other penalty or tax that may be imposed upon that person or any other person liable for tax or penalty.
