1.2 Purpose and Scope
1.2.1 This recommended practice is a guide to procedures and equipment that should be used for the proper installation of underground petroleum storage systems. It is intended for use by architects, engineers, tank owners, tank operators, and contractors. 1.2.2 This recommended practice applies to underground storage tank systems (see 1.3.48) that are used to store petroleum products at retail and commercial facilities. The stored products include gasoline, diesel fuel, kerosene, lubricating oils, used oil, and certain alcohol/gasoline blends. (For information on alcohol/gasoline blends, see API Rec- ommended Practices 1626 and 1627.) The product manufac- turer and the authority having jurisdiction (see 1.3.1) should be consulted with regard to the proper storage of all prod- ucts. 1 .2.3 Anyone preparing to design or install an under- ground storage tank system should investigate the federal, state, and local requirements and current methods of compli- ance for vapor recovery in that region. Vapor recovery (see 1.3.52) is covered in greater detail in Section 12 of this doc- ument. For more information on the design and installation of vapor recovery systems, see NFPA 30A or PEI RP 300. 1.2.4 The primary application of this recommended prac- tice is in connection with the underground storage of bulk petroleum products or used oil at retail and commercial facil- ities. It is not intended to cover specialized installations, such as fuel storage systems at marinas or airports, heating oil storage systems (either residential or bulk), or systems in- stalled inside buildings. This recommended practice does not apply to the installation of in ground or aboveground bulk storage systems. The reader is referred to the following stan- dards for information on specialized storage systems: a. Marinas: NFPA 30A. b. Residential storage of heating oil: NFPA 31. c. Storage inside buildings: NFPA 30.
2.1 General
2.1.1 Because many site-specific factors related to soil conditions and drainage affect the safety and operational life of an USTS, it is necessary to conduct a preinstallation site analysis. Factors analyzed may include but are not necessar- ily limited to soil stability, underground rock soil resistivity, acidity (Ph), moisture content, sulfide content, structures (existing on-site or nearby), utilities, space availability, nearby potable water wells, and the presence or absence of contamination. The preinstallation site analysis should also include an evaluation of possible requirements for secondary containment (see 2.2 and 6.3). 2.1.2 The preinstallation site analysis should evaluate the site-specific needs for groundwater protection and personal safety. This may include identification of potable water wells and take into account residential areas in close proximity to the site (see 2.2). The preinstallation site analysis should also include the location and identification of nearby structures, such as utility lines, sewer lines, buildings, and other tanks that may influence the location and design of the USTS. In addition, a determination should be made of the soil stability and soil composition with respect to the systems to be in- stalled (for example, loading pressure). Soil corrosivity need not be evaluated if the tanks, piping, and containment hard- ware to be installed are made of noncorrosive materials, for example, FRP, high density polyethylene (HDPE).
