 LG 143 - REGULATORY STATUS OF HYDRANT FUELING SYSTEMS AT CALIFORNIA AIRPORTS

January 19, 1996

To: Local Agencies and Other Interested Parties

The question has been asked whether hydrant fueling systems at California airports are subject to the California underground storage tank (UST) law [Chapter 6.7, Health and Safety Code (H&SC)]. The answer depends on certain conditions as explained below:

PIPING

If refined fuel is delivered to bulk storage farms at airports by pipeline, the piping (called a "hydrant fueling system") that carries the fuel from the bulk storage farm to each terminal is regulated by the State Fire Marshal's Office (SFM) in accordance with the Pipeline Safety Act. In California, there are four airports in this category: San Francisco International, Los Angeles International, Oakland International, and a portion of Ontario International. These hydrant fueling systems are exempt from regulation under Section 25281.5(a)(2), Chapter 6.7 H&SC.

If the fuel is delivered to bulk storage farms by truck, the underground piping that takes the fuel from the bulk storage farms to the terminals is subject to Chapter 6.7 H&SC (if 10% or more of the storage system is underground).

TANKS

The SFM does not regulate tanks connected to hydrant fueling systems.

Aboveground tanks connected to hydrant fueling systems are not subject to Chapter 6.7 H&SC (unless 10% or more of the storage system is underground). However, these tanks may be subject to the Aboveground Petroleum Storage Act (Chapter 6.67 H&SC).

Underground storage tanks connected to hydrant fueling systems at all airports are subject to Chapter 6.7 H&SC.
