C. Drums and other types of containers holding regulated substances and wastes of such substances as defined in this section shall be stored with secondary containment.
(b) Existing containment systems and procedures shall not be removed, nor shall their ability to contain spills be compromised, so long as regulated substances are stored, transferred or used within the containment areas. Containment systems shall be maintained in good working order. Improvements and/or addition to containment systems may be performed so long as the ability to contain a spill is not compromised. Temporary approved containment systems may be required during maintenance and/or improvements activities.

(2) Mixtures of chemicals, which have been tested as a whole and have been determined to be a health hazard.
(3) Mixtures of chemicals which have not been tested as a whole but which contain any chemical which has been determined to be a health hazard and which comprises one percent (1%) or greater of the composition on a weight per unit weight basis, and mixtures of chemicals which include a carcinogen if the concentration of the carcinogen in the mixture is one-tenth percent (0.1%) or greater of the composition on a weight per unit weight basis.
(4) Ingredients of mixtures prepared within the “WP” Wellhead Operation/Protection District in cases where such ingredients are health hazards but comprise less than one-tenth (0.1%) of the mixture (on a weight per unit weight basis) if carcinogenic or less than one percent (1%) of the mixture (on a weight per unit weight basis) if non-carcinogenic.
(5) Petroleum and non-solid petroleum derivatives (except no-PCB dielectric fluids).
