Significance and Use4.1 This guide is an educational tool for tank owners,operators, and other users and is not intended for use incertifying compliance with the Federal technical standards forunderground storage tanks.4.2 The intent of this guide is to provide an overview of thegene
24、ral requirements. This guide is intended for users who aregenerally familiar with the requirements of 40 CFR Part 280.The user is advised that this guide does not contain the level ofdetail necessary to make the determination of whether specificequipment or services meet the detailed technical perfo
25、rmancerequirements of 40 CFR Part 280.4.3 This guide does not cover state and local requirements,that can be more stringent than the federal rules. Owners andoperators are responsible for meeting federal, state, and, insome circumstances, local requirements. It is recommendedthat owners and operator
26、s familiarize themselves with theserequirements as well.4.4 Owners or operators may use the sample checklist inAppendix X1 to assist them in determining operational con-formance or they may develop their own checklist based uponthis guide.4.5 This guide and accompanying appendixes are not in-tended
27、to be used by state or local UST program authorities asa regulatory or administrative requirement for owners oroperators. Use of this guide and appendixes by owners andoperators is intended to be a voluntary educational tool for thepurposes described in 4.1.5. UST System Requirements5.1 Operational
28、ConformanceFor an underground storagetank (UST) system to be in operational conformance with 40CFR Part 280, it must have release detection, corrosionprotection, spill prevention, and overfill protection.5.2 Release DetectionTo meet all release detectionrequirements, release detection for both tank
29、and piping isrequired.5.2.1 Petroleum Tanks These tanks may meet releasedetection requirements by use of one of the following:5.2.1.1 Monthly monitoring using one of the following:automatic tank gauging, vapor monitoring, interstitialmonitoring, ground water monitoring, statistical inventoryreconcil
30、iation (SIR), and any other approved method5.2.1.2 Monthly inventory control and annual tank tightnesstesting (may be used for existing UST systems which have notbeen upgraded to meet Federal regulations at 40 CFR Part280.21).5.2.1.3 Monthly inventory control and tank tightness testingevery five yea
31、rs (may start when new UST systems and USTsystems that have been upgraded with spill prevention andoverfill and corrosion protection meet the Federal regulationsat 40 CFR Part 280.20 or 280.21). This release detectionmethod must be replaced or augmented with one of the optionsin 5.2.1.1 at the later
32、 of two datesDecember 22, 1998 or tenyears after the tank was installed or upgraded with corrosionprotection.5.2.1.4 Manual Tank GaugingThis release detectionmethod is for tanks of 2000-gal capacity or less. This techniquemay be used if the tank meets the size, test duration, andstandard variation r
33、equirements listed in Table 1:5.2.2 PipingPiping may meet release detection require-ments by use of one of the following:5.2.2.1 Pressurized PipingTo meet release detection re-quirements for pressurized piping, it is necessary to choose onemethod from 5.2.2.2 and one method from 5.2.2.4 (or a single
34、method that satisfies both sections).E1990 1425.2.2.2 Choose one of the following: automatic flowrestricter, automatic shutoff device, and continuous alarmsystem.5.2.2.3 Each of these methods must be tested on an annualbasis in accordance with the manufacturers requirements.5.2.2.4 Choose one of the
35、 following: annual line tightnesstesting, monthly monitoring using one of the following: vapormonitoring, ground water monitoring, interstitial monitoring,SIR, other approved methods, such as: electric or electronicline leak detector, and continual reconciliation.5.2.2.5 Suction Piping For suction p
36、iping, you maychoose one of the following:5.2.2.6 Monthly monitoring using one of the following:vapor monitoring, ground water monitoring, interstitialmonitoring, SIR and, other approved methods.5.2.2.7 Line testing every three years.5.2.2.8 No leak detection requirements if the piping meetsthe foll
37、owing criteria:5.2.2.9 The below-grade piping operates at less than atmo-spheric pressure.5.2.2.10 The below-grade piping is sloped so that thecontents of the pipe will drain back into the storage tank ifsuction is released.5.2.2.11 Only one check valve is included in each suctionline and it is loca
38、ted directly below and as close as practical tothe suction pump.5.2.2.12 Satisfying the preceding requirements must be ableto be easily determined.5.2.3 Hazardous Substance TanksRelease detection forhazardous substance tanks must meet one of the following:5.2.3.1 Existing UST systems(1) Until Dec. 2
39、2, 1998, existing hazardous UST systemsmay meet the release detection requirements as described in5.2.1.(2) By Dec. 22, 1998, all hazardous UST systems mustmeet the new system requirements described in 5.2.3.2.5.2.3.2 New UST systems(1) Unless an owner or operator has applied for andreceived a varia
40、nce from the implementing agency, newhazardous substance UST systems must have each of thefollowing: secondary containment, and monthly interstitialmonitoring.5.3 Corrosion ProtectionAll underground tanks and pip-ing must be protected from corrosion.5.3.1 TanksAny portion of the tank that is undergr
41、oundand routinely contains product must have corrosion protection.The following may be used to meet corrosion protectionrequirements for tanks:5.3.1.1 Coated and cathodically protected steel,5.3.1.2 Cathodic protection added,5.3.1.3 Interior lining added,5.3.1.4 Cathodic protection and interior lini
42、ng added,5.3.1.5 Fiberglass reinforced plastic,5.3.1.6 Steel tank clad with a noncorrodible material, and5.3.1.7 Other construction accepted by the implementingagency.5.3.1.8 Corrosion experts determination that the site is notcorrosive enough to cause it to have a release during theoperating life o
43、f the tank.5.3.2 PipingPiping that routinely contains regulated sub-stances and is in contact with the ground must be protectedfrom corrosion. The following may be used to meet corrosionprotection requirements for piping:5.3.2.1 Coated and cathodically protected steel,5.3.2.2 Cathodic protection add
44、ed,5.3.2.3 Fiberglass reinforced plastic,5.3.2.4 Other construction accepted by the implementingagency, and5.3.2.5 Corrosion experts determination that the site is notcorrosive enough to cause it to have a release during theoperating life of the piping.5.4 Spill Prevention and Overfill ProtectionTan
45、ks thatreceived regulated substances in quantities greater than 25 galat one filling need to have spill prevention and overfillprotection.5.4.1 To meet the spill prevention requirement, equipmentthat will contain the product in the transfer hose when thetransfer hose is detached from the fill pipe (
46、for example, acatchment basin) must be used to prevent release of product tothe environment.5.4.2 To meet overfill protection requirements, one of thefollowing must be used:5.4.2.1 Automatic shutoff device,5.4.2.2 Overfill alarm, and5.4.2.3 Ball float valve.5.4.3 Compatibilityowners and operators of
47、 USTs arerequired to use UST systems made of or lined with materialsthat are compatible with the substance stored in the USTsystem (40 CFR 280.32). In accordance with the EPA Office ofUnderground Storage Tanks June 2011 guidance, tank ownersmay demonstrate compatibility of UST system equipment byusi
48、ng components that are certified by the manufacturer orlisted by a nationally recognized, independent testing labora-tory for use with the fuel stored.TABLE 1 Guide for Owners and OperatorsTank SizeMinimumDuration ofTest, hWeeklyStandard(One Test),galMonthlyStandard (Four-Test Average),galUp to 550
