(i) Cathodic protection tester means a person who can demonstrate an understanding of the principles and measurements of all common types of cathodic protection systems as applied to metal portions of tank systems in contact with the ground. At a minimum, such persons must have education and experience in soil resistivity, stray current, structure-to-soil potential, and component electrical isolation measurements of metal portions of tank systems in contact with the ground.
(j) Class A operator means the individual who has primary responsibility to operate and maintain the UST system(s) at a facility in accordance with applicable requirements of this Part. The class A operator typically manages resources and personnel to achieve and maintain compliance with the requirements of this Part.
(k) Class B operator means the individual who has day-to-day responsibility for implementing applicable requirements of this Part. The class B operator typically implements field aspects of operation, maintenance, and associated recordkeeping for a UST system.
(l) Class C operator means the individual who has primary responsibility for initially addressing emergencies presented by a spill or release from a UST system. The class C operator typically controls or monitors the dispensing or sale of petroleum.
(m) Compatible means, in the case of two or more substances, able to maintain their respective physical and chemical properties upon contact with one another for the design life of the tank system under conditions likely to be encountered in the tank system.
(n) Containment means equipment that limits or prevents the spread of a petroleum release.
