<br />lhe rule. This seclion todny contains
<br />severel terms thnt were not defined in
<br />the proposed rule. These lerms heve
<br />bcen included loday in respanse to
<br />t requests trom commentera or lo clnrify
<br />other lerms used in today'e rule. These
<br />terms include cathadic protection tester,
<br />dieleclric materinl. molntenence, pipe o
<br />piping, repulr, end upgreding. Severel
<br />terms Ihal nppeared in Ihe proposed nile
<br />do nol nppear in this ser.lion o[ the

<br />summnries and responses) in �eclion
<br />IV.D. of loday's preamble ond include

<br />seclion in IV.A.1.
<br />Finally, several terms have not

<br />nol inr.luded here: Eleclrical equipmenl;
<br />operuliunni li(e; overfill telease: positive
<br />sampling, lest, ar maniloring resulls;
<br />release deleclion; and underground
<br />releese. Explanalions of these lerms eze
<br />[ound in lhe preamble lo the April 1907
<br />proposal.
<br />(7J Fl Goreground Release.
<br />"A6uvegruund release" menns any
<br />relcase to the surtace of the land or ro
<br />sur(ace wnter. This includes, but is nat
<br />limited to, releases from the
<br />aboecground porlion o[ an underground
<br />slorage tank system and aboveground
<br />relenses associaled wilh ovetfills an�
<br />lransfr.r operalions as lhe regulaled
<br />substance moves to vr from an UST
<br />syslem.
<br />Two commenters asked it the
<br />�pplica6ilily of this term is determined
<br />Ly whr.rc lhe malcrial escapes the UST
<br />or �.•here il is evenWally found.
<br />Commenlers stated that a relense (rom
<br />bclow 1he ground may evenumlly
<br />migrnle to the sur[aca end a spill lo lhe
<br />ground could in(illralr, inlo the
<br />subsurface. The Agency has inlerpreled
<br />this term lo apply to all leaks trom thr.
<br />uboveAround porlion o[ an UST,
<br />includin� spills and ovcrfills. The sourr.e
<br />o( a leak, ralher lhen its ultimale

<br />pelroleum or hazardous substances to
<br />and (rom an underground sloragc tank.
<br />1'his detinilion has nol chnnged eince
<br />the proposed rule. Some commenters
<br />asked iE certain equipmenl, such es
<br />aboveground melers and pumps, wes
<br />considered to be encillary equipment
<br />end lo whut extent such equipmenl
<br />would bc regulaled. EPA hns clarified
<br />the discussion of encillary equipment in
