PART 281_APPROVAL OF STATE UNDERGROUND STORAGE TANK PROGRAMS--Table 
of Contents
 
            Subpart A_Purpose, General Requirements and Scope
 
Sec. 281.12  Scope and definitions.

    (a) Scope. (1) The Administrator may approve either partial or 
complete state programs. A ``partial'' state program regulates either 
solely UST systems containing petroleum or solely UST systems containing 
hazardous substances. If a ``partial'' state program is approved, EPA 
will administer the remaining part of the program. A ``complete'' state 
program regulates both petroleum and hazardous substance tanks.
    (2) EPA will administer the UST program on Indian lands, except 
where Congress has clearly expressed an intention to grant a state 
authority to regulate petroleum and hazardous substance USTs on Indian 
lands. In either case, this decision will not impair a state's ability 
to obtain program approval for petroleum and/or hazardous substances on 
non-Indian lands in accordance with this part.
    (3) Nothing in this subpart precludes a state from:
    (i) Adopting or enforcing requirements that are more stringent or 
more extensive than those required under this part; or
    (ii) Operating a program with a greater scope of coverage than that 
required under this part. Where an approved state program has a greater

scope of coverage than required by federal law, the additional coverage 
is not part of the federally-approved program.
    (b) Definitions. (1) The definitions in part 280 apply to all 
subparts of this part.
    (2) For the purpose of this part, the term interim approval means 
the approval received by a state program that meets the requirements in 
Sec. 281.11(c) (1) and (2) for the time period defined in Sec. 
281.11(c)(3).
    (3) For the purposes of this part the term final approval means the 
approval received by a state program that meets the requirements in 
Sec. 281.11(b).
