§470. Permit to Operate.

(a) Except during the time a request for a permit remains unacted upon, no employer or employee shall use or cause to be used any pressure vessel for the storage or transportation of LP-Gas without first securing from the Division a permit to operate such container.

Exception: No permit to operate shall be required for pressure vessels of 125 gallons capacity or less or for cylinders used, inspected, and maintained in accordance with DOT regulations.

(b) Permits to operate dispensing units, trap tanks, and skid tanks shall expire in not more than 3 years while the permit to operate transportation tanks, mobile fuel tanks, and storage tanks shall expire in not more than 5 years.

It is intended that failure to maintain the installation in compliance with these Safety Orders will be justification to void the permit and require reinspection.

(c) The permit to operate any tank shall expire when any of the following occurs:

(1) The tank changes both ownership and location.

(2) Alterations are made which affect the safety of the installation.

(3) The tank has suffered mechanical or fire damage.

The permit to operate shall not expire due to the exchange or interchange of approved appurtenances intended for the same purposes.

(d) The permit to operate, or an acceptable copy, shall be kept readily available on the premises upon which the tank is located and shall be available at all times to any qualified inspector. In the case of a transportation or portable tank, the permit may be carried in the cab of the towing vehicle or in a suitable weatherproof container secured to the unit.

(e) No person shall charge LP-Gas into any tank requiring a permit to operate unless the permit to operate has been issued and posted, except where a request for a permit remains unacted upon. Containers shall be filled or used only upon authorization of the owner.

(f) No permit to operate shall be issued for any tank until all provisions of these Orders have been complied with and the required fee has been paid.

(g) Any tank that has been used for the storage or transportation of products other than LP-Gas shall be inspected internally by a qualified inspector at the time of the periodic inspection required by Section 470 (i) .

(h) At the time of the first field inspection of each tank requiring a permit to operate, the qualified inspector shall stamp on the tank a state serial number in accordance with Section 462 (h) .

(i) Except as permitted in Section 470 (a) each LP-Gas tank shall be inspected in accordance with the intervals shown in Section 470 (b) .

(j) Inspectors shall be certified in accordance with Section 463.
