1 General
1.1 SCOPE
This standard provides minimum recommendations for the interior lining of existing steel and Þberglass reinforced plas- tic underground tanks and periodic inspection of steel under- ground tanks used for the storage of petroleum-based motor fuels and middle distillates. These recommendations include procedures to be followed and operating conditions to be maintained by contractors, workers and engineers preparing, inspecting, testing and lining the interiors of existing under- ground storage tanks. Requirements for vapor-freeing tanks, removing sediment and cleaning interior surfaces of steel and Þberglass tanks as well as guidelines to identify tanks that are suitable for lining, are also included. All work associated with the interior lining and periodic inspection of underground storage tanks shall be accomplished in accordance with appli- cable federal, state, and local regulations, including applica- ble environmental and safety requirements.
1.3 EPA TECHNICAL STANDARDS
The U.S. Environmental Protection Agency (EPA) issued its Technical Standards and Corrective Action Requirements for Owners and Operators of Underground Storage Tanks (UST) (herein referred to as ÒTechnical StandardsÓ) in 1988. These regulations can be found in the Code of Federal Regu- lations at 40 CFR Part 280. In addition, legislation and regu- lations on all aspects of underground storage tank management have been developed by state and local jurisdic- tions that may have requirements other than those speciÞed in the EPA Technical Standards. Therefore, employers should consult the appropriate government agencies responsible for implementing an approved underground storage tank pro- gram within a geographic area of interest, and determine the applicable requirements before any action recommended or suggested by this standard is taken. The EPA Technical Standards allow this standard to be used as a guide for compliance with EPAÕs requirements for interior lining and periodic inspection of underground storage tanks. In some respects, the requirements of this standard may be more stringent than the EPA Technical Standards. In addition, this standard is not intended to cover all of the sub- jects included in the EPA Technical Standards. While sub- stantial effort has been made to ensure that none of this standardÕs requirements contradict those of the EPA Techni- cal Standards, the API is not undertaking to interpret the EPA Technical Standards and cannot guarantee that the recom- mendations in this standard are completely in accord with them. Also, the API makes no representation that the require- ments of this standard conform with any requirements imposed by state and local agencies.
