13 dsfsdf CHAPTER 1.0 Introduction This Guide will help you prepre to tke the New York Stte Clss A nd/or Clss B Opertor exm. Successfully pssing the exm will uthorize you to operte underground storge tnks (USTs) t fcilities registered in New York Stte (NYS). Note: Becuse most NYS registered fcilities store petroleum, this Guide is focused on petroleum bulk storge (PBS) tnk systems. While much of this informtion lso pplies to chemicl bulk storge (CBS) fcilities, there re importnt differences, prticulrly for registrtion, inspections, nnul evlutions, spill response plns, nd tnk system comptibility. In ddition, ech of the dozens of regulted chemicls hs unique sfety nd comptibility requirements. Therefore, in ddition to lerning the bsic informtion in this Guide, it is importnt tht CBS opertors be trined on the procedures nd requirements for the specific chemicls stored t ech fcility t which they re uthorized. At minimum, ll Clss A nd B Opertors must understnd the generl requirements for CBS tnk systems described in Chpter A/B This Guide will help you prepre to tke the New York Stte Clss A nd/or Clss B Opertor exm. Successfully pssing the exm will uthorize you to operte underground petroleum nd chemicl storge tnks t fcilities registered in New York Stte. 1.1 Why Does New York Require UST Opertor Testing? Leks from USTs cn seep into the soil nd contminte groundwter, the source of drinking wter for nerly qurter of ll New Yorkers. Spills, leks, nd overfills cn lso flow into lkes, rivers, nd strems where the oil or chemicls cn hrm people nd the environment, including wildlife, fish, nd plnt life. For severl decdes, up into the mid-1980s, most USTs were single-wlled, bre steel tnks, often instlled with unprotected metl piping. As these systems ged, releses due to corrosion nd overfills of these tnk systems becme widespred nd cused impcts so serious tht both New York Stte nd the federl government pssed lws to set operting requirements nd tnk construction stndrds to protect humn helth nd the environment. Thousnds of tnks were upgrded or replced, usully with double-wlled tnks mde of fiberglss or protected steel nd equipped with methods for detecting unseen leks nd preventing overfills. 1-1 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

14 Chpter 1: Introduction However, good equipment only prevents leks nd spills IF it is operted nd mintined properly. While the number of spills hs decresed, thousnds of spills re still reported ech yer in New York lone, often due to improper tnk system mngement. In 2008, new stte lw required tht tnk opertors be trined to properly operte, mintin, nd document their systems. The lw lso gve New York Stte the uthority to prohibit deliveries to tnks tht re in serious noncomplince with regultory requirements. The New York Stte Deprtment of Environmentl Conservtion (DEC) hs developed regultions to implement the requirements for PBS nd CBS UST opertor trining. No lter thn October 11, 2016, fcilities with underground petroleum or chemicl storge tnks tht re subject to New York Stte nd federl regultion must designte t lest one Clss A, one Clss B, nd one Clss C Opertor for those tnks. If you wish to become Clss A nd/or B Opertor, you must pss n exm dministered by DEC. Alterntively, you my qulify for uthoriztion by obtining credentils issued by ny stte progrm recognized by the U.S. Environmentl Protection Agency (EPA) s meeting opertor trining grnt guidelines. Along with the new regultions, DEC hs developed this Guide to help you prepre for the New York Stte exm, but you my use whtever trining mterils you choose. DEC will not review third-prty trining mterils, nor will it require third-prty triners to be certified or otherwise pproved. Pssing the exm demonstrtes tht you hve the bsic knowledge required for proper opertion of USTs. However, you must lso become fmilir with the detils of the tnk systems nd opertions t your own fcility so tht you cn operte, mintin, nd document tht the systems re in complince with regultory requirements. 1.2 Applicbility The requirement to hve uthorized opertors pplies to USTs t PBS fcilities regulted under 6 NYCRR nd USTs t CBS fcilities regulted under 6 NYCRR These include fcilities tht hve petroleum USTs with individul cpcities of more thn 110 gllons. There re exceptions for certin USTs tht: (1) contin heting oil used for onsite consumption; (2) hve design cpcity of 1,100 gllons or less nd re used to store motor fuel for noncommercil purposes (not for resle) t frm or residence; (3) re prt of n emergency genertor system t nucler power genertion fcilities; OR Leks from underground storge tnks (USTs) cn seep into the soil nd contminte groundwter, the source of drinking wter for nerly qurter of ll New Yorkers. While the number of spills hs decresed, thousnds of spills re still reported ech yer in New York lone, often due to improper tnk system mngement.

15 Chpter 1: Introduction Chpter 4 provides more detils on the definition of regulted PBS fcility. Chpter 19 provides informtion on CBS fcilities. 1.3 Trining nd Testing: Timing Requirements Clss A Opertors hve primry responsibility for opertion nd mintennce of UST systems. These opertors typiclly mnge resources nd personnel to mintin complince. Trining for Clss A Opertors should help the opertor mke informed decisions regrding complince with regultory requirements. Clss B Opertors hve dily responsibility for onsite opertion nd mintennce of UST systems. Trining for Clss B opertors should provide n in-depth understnding of opertion nd mintennce spects of UST systems. Clss C Opertors re onsite individuls who re generlly the first line of response to ctul or potentil emergencies. The Clss C Opertor must be trined to tke pproprite ction in response to UST-relted emergencies or lrms cused by spills or leks from n UST system. A person my be designted to more thn one opertor clss s long s they re properly trined nd uthorized in ech opertor clss for which they re designted. New fcilities must designte opertors when they commence opertion. Clss A nd B Opertors t those fcilities then hve 30 dys to become uthorized. Clss C Opertors must be trined before they re designted. Fcilities where opertor trining is required nd tht re lredy operting on October 11, 2015 will hve until October 11, 2016 to designte uthorized opertors nd for those opertors to trin Clss C Opertors. 1.4 Opertor Testing Requirements Clss A nd B Opertors must pss the DEC exm. DEC will lso ccept vlid opertor trining verifiction issued by nother stte (i.e., reciprocity) tht is recognized by EPA s meeting opertor trining grnt guidelines. Clss A nd B uthoriztion does not expire unless revoked by DEC due to significnt noncomplince with regultory requirements. Clss A Opertors hve primry responsibility for opertion nd mintennce of UST systems. Clss B Opertors hve dily responsibility for onsite opertion nd mintennce of UST systems. Clss C Opertors re onsite individuls who re generlly the first line of response to ctul or potentil emergencies. Clss C Opertors must be trined by Clss A or B Opertor; their knowledge must be ssessed nd the trining must be documented, but written exm is not required. Clss C Opertor trining does not expire, but it is good prctice for the Clss C Opertor to periodiclly receive refresher trining. 1-3 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

16 Chpter 1: Introduction 1.5 Red Tgs Regultory Consequences of Releses or Serious Deficiencies Certin serious problems t your site my cuse DEC to prohibit deliveries of product to your tnks. The prohibition is known s red-tgging becuse DEC will ttch tg to the tnk fill pipe to notify fuel suppliers tht they my not deliver fuel to tht tnk. The most serious problems, known s Tier 1 conditions, will result in the tnk being tgged when the problem is discovered. Tier 1 conditions include tnk system tht is known to be relesing petroleum, or tnk system tht is missing required: secondry continment; spill nd overfill prevention; corrosion protection; or lek detection. Tier 2 conditions my result in DEC tgging the tnk fter written notifiction to the fcility. These conditions include: lek detection results tht indicte the tnk system my be leking, or would not contin lek if one occurred; or filure to comply with stndrds for secondry continment, spill/overfill prevention, corrosion protection, or lek detection within 30 dys following written notice from DEC. Delivering fuel to red-tgged tnk or tmpering with the tg is illegl nd my result in enforcement ctions including substntil fines. For dditionl informtion bout the red tg process, see Subprt of the PBS regultions. Complete PBS regultions re t 6 NYCRR 613 of New York s regultory code. The complete CBS regultions re t 6 NYCRR See Section 20.0 for links to the regultions online. Certin problems t your site my cuse DEC to prohibit deliveries of product to your tnks. The informtion in this Guide cn help you keep your tnk system running in complince with these regultory requirements. Disclimer: The informtion in this Guide cn help you keep your tnk system running in complince with regultory requirements, but it is NOT substitute for the regultions. 1.6 Summry Your responsibility s tnk opertor is to prevent releses of petroleum products or hrmful chemicls to the environment nd to keep your fcility in regultory complince. 1-4 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

Clss A Opertors hve primry responsibility for opertion nd mintennce of the UST system. Clss B Opertors hve dily responsibility for onsite opertion nd mintennce of UST systems. Clss C Opertors re onsite individuls who re generlly the first line of response to ctul or potentil emergencies. Clss A nd B Opertors must pss the DEC exm or n exm dministered by nother stte recognized by EPA s meeting opertor trining grnt guidelines. Clss C Opertors re trined by Clss A or B Opertor. Clss C Opertors must hve their knowledge ssessed, nd their trining must be documented, but written exm is not required. Certin serious problems t your site my cuse DEC to prohibit deliveries of product to your tnks. The informtion in this Guide cn help you keep your tnk system operting in complince with regultory requirements, but it is not designed to replce the regultions. Clss A nd B Opertors must understnd the generl requirements for CBS tnk systems described in Chpter 19. It is importnt tht CBS opertors be trined on the specific procedures nd requirements for ech fcility t which they re uthorized. Your responsibility s tnk opertor is to help prevent releses of petroleum products or hrmful chemicls to the environment nd to help keep your fcility in regultory complince. 1-5 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

22 Chpter 2: Opertor Trining Requirements nd Dedlines Retesting s Result of Noncomplince ( (e)) Authorized opertors re not required to be retested unless DEC finds significnt noncomplince t one or more UST systems where the opertor hs been designted. (Chpter 1 hs dditionl informtion on significnt noncomplince.) If DEC finds fcility to be in significnt noncomplince, the opertor must be retested by tking the NYS exm regrdless of how the opertor ws previously uthorized. Opertors who need to be re-uthorized my use ny trining method they desire. They must retke nd pss the exm for the opertor clss for which they wish to be uthorized. Opertors must complete the exm within 30 dys fter being notified by DEC tht reuthoriztion is required. If the opertor is unble to complete the exm online nd the next inperson exm offering is more thn 30 dys fter the time of being notified by DEC, the opertor must contct DEC for n extension. If no extension is given or the opertor does not chieve pssing score on the exm, the tnk owner must designte new opertor within 30 dys fter being notified of the need for reuthoriztion. If DEC observes tht Clss A or Clss B Opertor is uthorized t one or more fcilities with continul noncomplince issues, DEC my revoke tht opertor s uthoriztion for specified period of time. Authorized opertors re not required to be retested unless DEC finds significnt noncomplince t one or more fcilities where the opertor hs been designted. 2.5 Clss C Opertor Clss C Opertors re onsite individuls who re generlly the first line of response to emergencies resulting from spill or relese from UST. Clss C Opertors re not required to pss n exm. However, you must tech your Clss C Opertors the emergency procedures they need to follow t your fcility nd verify tht they understnd nd cn implement those procedures. Chpter 18.0 hs dditionl informtion on trining nd documenting Clss C Opertors.

Although re-trining Clss C Opertors is not required, it is good ide to check their knowledge of emergency procedures from time to time by sking questions such s: Wht should you do if the monitoring system lrms?, Where is the emergency shut-off, nd when should you ctivte it?, or Where do we keep the tnk records?. 2.6 Documenttion Every fcility tht is required to hve uthorized opertors must mintin list of their designted Clss A, Clss B nd Clss C opertors. The list must: identify ech Clss A, Clss B nd Clss C opertor t the fcility for s long s the opertor is designted AND for n dditionl 3 yers; nd include the nme of the opertor, clss of the opertor, dte tht the opertor ws designted, dte the opertor initilly completed testing or trining nd the dte of ny retesting. In ddition, ll Clss C opertor records must include the nme nd uthoriztion number of the Clss A or B Opertor tht trined them. Every fcility tht is required to hve uthorized opertors must mintin list of their designted Clss A, Clss B nd Clss C opertors. Records verifying completion of testing, trining or retesting must be recorded on pper or electroniclly for ll opertor clsses. Opertor uthoriztion number should lso be dded to ny list of designted Clss A or B Opertors. Opertor uthoriztion number should lso be dded to the list of designted Clss A or B Opertors. 2.7 Opertor Dtbse DEC will mke the list of currently uthorized opertors vilble online on its website. This informtion will be limited to opertor nme, identifiction number, nd uthoriztion dte. If re-uthoriztion is required for designted opertors, then DEC will remove the nme of the opertor from the list until the opertor hs completed the re-uthoriztion process. 2.8 Retirement of Authoriztion Opertor uthoriztion does not expire unless the opertor is found to be ssocited with 2-6 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

This is n introductory discussion only, nd does not include every possible component or design. For dditionl informtion on tnk systems, see the references provided in Chpter USTs re petroleum storge tnks tht re 10% or more underground. Tnks locted in underground vults, but with ll sides visible for inspection, re not considered USTs. While ech UST fcility is unique, ll systems consist of common components tht llow for the storge, delivery, monitoring nd dispensing of petroleum. Tnk System Knowledge Know your UST system to prevent spills. Mintin the vrious components of your UST system to ensure proper opertion. USTs store petroleum products underground. The tnk holds product t tmospheric pressure, mening t the sme pressure s the ir round us. All tnks hve fill pipe to bring product into the tnk nd suction or pressurized piping system to tke product out. All tnks lso hve vent line to llow the tnk to brethe by relieving tnk pressure. Figure 3.1 illustrtes these concepts. Figure 3.1 Bsics of Tnk Construction 3-1 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

29 Chpter 3: Tnk System Bsics 3.1 Tnk System Ctegories According To Instlltion Dtes The DEC PBS regultions divide UST systems into three distinct ctegories: Ctegory 1 Tnk System: Any tnk system whose tnk ws instlled before December 27, Ctegory 2 Tnk System: Any tnk system whose tnk ws instlled between December 27, 1986 nd October 11, Ctegory 3 Tnk System: Any tnk system whose tnk ws instlled fter October 11, Different regultory requirements my pply to tnks in different ctegories. 3.2 Tnk Construction USTs re either single- or double-wlled. Single-wlled tnks consist of single, primry tnk. Double-wlled tnks, by comprison, consist of two tnks primry tnk surrounded by secondry tnk seprted by n interstitil spce (lso known s the interstice). The purpose of the secondry tnk is to prevent relese into the environment in the event of lek within the primry tnk. In double-wlled tnk, the interstitil spce is the spce between the primry tnk wll nd the secondry tnk wll. It cn be fitted with lek detection system to detect leks in the primry or secondry tnk, nd is normlly ccessed through n inspection port in the tnk pd. See Figure 3.3 to lern where you cn expect to find n interstitil monitoring port. Chpter 9.0 hs more informtion bout interstitil monitoring. In ddition to single- nd double-wlled design, USTs my be constructed from vriety of mterils, s summrized below. Fiberglss Reinforced Plstic (FRP) A fiberglss-reinforced plstic (FRP) UST my be single- or double-wlled. FRP is commonly used becuse it is corrosion resistnt nd durble in underground environments. FRP tnks meet corrosion protection requirements without ny extr equipment or operting requirements. FRP tnks do not require cthodic protection Figure 3.4: Double-wlled FRP tnk redy for instlltion 3-4 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

30 Chpter 3: Tnk System Bsics Jcketed Steel Jcketed steel tnks re steel tnks tht re enclosed by non-corrodible, nonmetllic mteril such s fiberglss, plstic or urethne. The tnks re constructed with spce between the steel wll nd the jcketed mteril where the tnk cn be monitored for leks. A cut-wy view of jcketed steel tnk is shown in Figure 3.5. Figure 3.5: Jcketed steel UST Steel Tnk with Dielectric Coting nd Cthodic Protection Steel tnks my lso be protected from corrosion by fctory-instlled corrosion resistnt coting nd cthodic protection (impressed current or scrificil nodes see Chpter 11). Tnks tht meet the Steel Tnk Institute sti-p3 specifiction Dielectric bushings re common exmples of this type of design. These tnks hve dielectric bushings t tnk openings to provide electricl isoltion of the tnk from piping or other components. Dielectric mens mteril tht does not conduct direct electricl current. A corrosion resistnt coting is instlled on the outer tnk wll. Anodes re then ttched to the outer tnk to prevent corrosion.

31 Chpter 3: Tnk System Bsics Steel Tnks with Internl Lining nd Cthodic Protection Internlly lined steel tnks re steel tnks tht hve spry-on lining inside the tnk to prevent internl corrosion. Scrificil nodes or n impressed current system re instlled outside the tnk to prevent corrosion on the exterior of the tnk. See Chpter 11 for more corrosion protection informtion. Cld Steel Tnks A cld steel tnk consists of steel tnk with thick lyer of non-corrodible mteril, such s fiberglss or urethne bonded to the outside. There is no interstitil spce between the steel tnk nd the non-corrodible coting. 3.3 Tnk Configurtions Tnks or piping systems my be configured in different wys. Knowing if there re connections nd how those connections re configured is importnt. Those configurtions determine how the tnk is registered nd wht type of lek detection system must be used. If product cn move between your tnks, if the dispensing piping from two or more tnks is connected, or if your system blends different grdes of fuel together, you must hve lek detection system nd inventory reconcilition method tht cn properly ccount for the effects of these connections Figure 3.7: Worker sprying lining on cthodiclly protected tnk Mnifolded/Siphoned Tnks In this configurtion, two or more tnks re connected together by siphon, which is pipe connected to two tnks of the sme product. The siphon uses grvity to Figure 3.8: Siphoned tnk llow product to move from one tnk to the other s product levels chnge. Siphoned tnks will tend to mintin the sme product level, s grvity will force product in the tnk with higher level into the tnk with lower level. There re some importnt things to remember bout mnifolded/siphoned, tnks: Product usully moves between the tnks slowly. As such, the siphon pipe cnnot move product s fst s the rte of delivery from truck, generlly mening tht the delivery vehicle will still hve to connect to both tnks when delivering to both tnks. 3-6 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

32 Chpter 3: Tnk System Bsics When tnks re mnifolded, the totl mount of product tht cn be relesed from filure in one of the tnks is the totl volume of BOTH tnks. This mens tht the two tnks mnifolded together tend to behve like single tnk. If in-tnk lek detection methods re used, the monitoring system hs to be progrmmed so tht the lek detection system trets the two tnks s single, lrge tnk. Siphons hve to initilly be primed to work. This mens tht priming tube must be connected to the submersible pump to crete suction nd drw fuel into the pipe. If the siphon line hs ny ir leks, or it is not properly primed, the siphon/mnifold will not work properly. Mnifolded Piping In system with mnifolded piping, the pipes leving two or more tnks contining the sme product re connected fter the product leves the submersible pumps. In this type of system, two or more tnks, ech with submersible pump, supply single combined pipe tht leds to the dispensers. Depending on the system, one pump my operte t time or both my operte together. There re some importnt things to remember bout mnifolded piping systems: Unlike the mnifolded/siphoned tnk configurtion, when the piping system is mnifolded, the totl mount of product tht cn be relesed from filure in one of the tnks is not ffected by the mnifold, nd therefore the contents of the tnk do not pssively communicte. As such, the two tnks behve like two independent tnks, in tht the tnk volumes re not combined when in the tnks. Submersible pumps in pressurized piping systems require utomtic line lek detectors. Becuse those lek detectors service common pipe in mnifolded piping systems, the lek detectors must be crefully selected nd configured to ensure tht they operte t the proper threshold. Becuse fuel from two or more tnks serves the sme dispensers in this configurtion, inventory reconcilition clcultions will hve to ccount for fuel s if it is coming from single tnk. Blending Systems: Vehicle fuel dispensers my dispense multiple grdes of product, such s low-grde, mid-grde, nd high-grde gsoline. Often, to void hving third tnk, the mid-grde fuel is blend of the 3-7 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

33 Chpter 3: Tnk System Bsics low- nd high-grde products. The low- nd high-grde products re piped from different tnks nd blended inside the dispenser. Blending systems do not involve the connection of tnks or piping systems (except t the dispenser), so the tnk nd piping lek detection systems re not ffected. A blending configurtion, however, will ffect how inventory reconcilition clcultions re performed. Comprtmented Tnks Comprtmented tnks re constructed with dividers (typiclly single-wlled) to crete two or more seprte sections within the primry tnk. Ech section is clled comprtment. Comprtmented tnks re most commonly used to seprte grdes of gsoline. Ech comprtment must be listed s seprte tnk on the fcility registrtion. Typiclly ech comprtment in given tnk hs the sme number followed by individul letters ( 1A, 1B, etc.).

Contined tnk top sumps will keep ny petroleum leks from entering the environment nd protect the components from corrosion by isolting them from the surrounding soil. Double-wlled piping systems re designed so tht leks in the piping will flow bck to the tnk top sump or the dispenser sump. Figure 3.12 shows tnk top sump contining product. Product in your sump mens tht you my hve lek in your primry piping. Wter in the sump my men tht you hve lek in your secondry piping, or it could be sign of lek in the sump or sump cover sels. Looking in your tnk top sump cn help you determine whether you hve pressurized or Figure 3.13: Suction piping system Figure 3.14: Pressurized piping system 3-10 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

36 Chpter 3: Tnk System Bsics suction piping system. A suction piping system hs pump locted inside the dispenser. The pump in the dispenser drws product from the tnk by suction. When you look into your tnk top sumps, you will find product piping but no pump (Figure 3.13). A pressurized piping system hs submersible turbine pump inside tnk, with the pump hed visible in tnk top sump. The submerged pump will pump product to your dispenser. When you look into your tnk top sumps you will find product piping nd submersible turbine pump hed (Figure 3.14). Dispensers Dispensers deliver product to your customers. They re prt of either pressurized or suction system. Figure 3.15 shows dispenser (left side) tht is prt of suction system. You cn see the suction pump locted inside the dispenser. The right-hnd photo in Figure 3.15 shows dispenser tht is prt of pressurized system. This dispenser does not house suction pump becuse the dispenser is served by submersible pump locted inside the tnk.

37 Chpter 3: Tnk System Bsics Dispensers my lso contin under-dispenser continment sumps (UDCs). UDCs re locted under your dispenser nd re designed to contin ny leks from the dispenser piping. UDCs re usully mde of fiberglss, steel or HDPE (plstic). You will be ble to see your UDC when you look down inside your dispenser cbinet. Dispenser sumps my lso contin electricl conduit to the dispenser meter, product piping nd fittings, nd sump lek sensor. Motor vehicle fuel dispensers served by pressurized piping systems must lso hve sher vlve. This is lso known s the emergency, impct, or crsh vlve. A sher vlve is designed to Figure 3.16: Typicl dispenser lyout stop product flow if cr strikes the dispenser or if fire occurs t the dispenser. The sher vlve loction is shown in Figure The vlve must be properly nchored nd instlled t the correct height. Spill Buckets Spill buckets re used t fill ports to prevent smll drips or spills from entering the environment. A spill bucket is liquid-tight continer tht surrounds the fill port. Spill buckets re commonly locted underground within the tnk pd. They ctch smll leks, drips or spills from the delivery hose tht my occur during delivery. Spill buckets must be ble to contin spills from leky fill connection or drips when the delivery hose is disconnected. Spill buckets must be kept clen nd dry. See Chpter 13: Spill Prevention for more informtion. Figure 3.17: Spill bucket 3-12 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

38 Chpter 3: Tnk System Bsics Product Piping It is importnt to know wht type of piping your fcility contins so tht you cn mintin nd monitor it properly. This section describes common underground piping systems tht my be present t your fcility. Single wlled piping does not hve secondry outer wll or interstitil spce. A lek from the pipe will be immeditely relesed into the environment. Double-wlled piping is pipe-within--pipe, or pipe encsed in n outer covering, with n interstitil spce between the two pipe wlls. The inner pipe is clled the primry pipe (lso known s the crrier pipe) nd the outer pipe is clled the secondry or continment pipe. Double-wlled piping should be monitored for leks with your lek detection system. Leks from the primry or secondry piping will run bck into your under-dispenser continment or tnk top continment sump nd cn be detected by lek sensor instlled in the sump or by weekly visul checks. Flexible piping is typiclly mde of non-corrodible nylon or Teflon. The piping my be fitted with metl connectors. As long s ny metl components re not in contct with soil, flexible piping meets corrosion protection requirements without dditionl equipment, opertion or mintennce. Flexible piping cn be either single- or double-wlled. Primry Pipe Secondry Pipe Interstitil Spce Figure 3.18: Double-wlled flexible pipe Figure 3.19: Flexible piping during instlltion Steel piping must be equipped with cthodic protection system to prevent corrosion of the piping by surrounding soils. Steel piping is usully single-wlled, but double-wlled steel piping is occsionlly used New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

39 Chpter 3: Tnk System Bsics FRP piping is constructed of non-corrodible fiberglss reinforced plstic (FRP) nd my be either single or double-wlled. FRP requires little mintennce nd cn be used with both pressurized nd suction systems. The piping my be fitted with metl connectors nd, s long s ny metl components re not in direct contct with soil, meets corrosion protection requirements without dditionl equipment, opertion or mintennce. Vent Lines Figure 3.20: FRP piping during instlltion All underground tnks re vented. Venting protects the tnk from dmge by llowing ir to flow in or out s the tnk is filled or emptied of product or s tmospheric pressure chnges. Venting lso llows deliveries to proceed normlly. Vent lines run underground from your tnk to vent stck which cn be ttched to building or stnd on its own. Every vent stck will hve vent top cover. Pressure vcuum vent (P/V vent) cps re required for gsoline tnks. The P/V vent cp prevents vpors from escping the tnk until the tnk reches pre-set pressure. When the tnk reches tht pressure, the vent will open to llow your tnk to brethe. Once the tnk pressure equlizes, the P/V vent will close in order to minimize vpor loss. A P/V vent cp will lso protect your tnk ginst the intrusion of wter, debris or insects. Tnks contining semi-voltile products (diesel, motor oil, kerosene, etc.) cn be vented with n open tmospheric vent cp. An open tmospheric vent cp hs n internl wire screen nd is designed to protect your tnk nd vent lines ginst the intrusion of wter, debris or insects. The vent is lwys open to the tmosphere nd will llow ny pressure or vcuum in the tnk to equlize.

Stge I systems operte during product delivery to the UST nd re required only for gsoline storge tnks. During delivery, the tnker truck opertes two hoses. One hose delivers product to the tnk, while the other hose tkes vpors out of the tnk nd bck to the truck. The vpor hose will typiclly hve Stge I vpor recovery dptor on the end. The dptor ttches to the vpor recovery riser pipe, which is typiclly ccessible in spill bucket. The dptor cretes tight sel to prevent vpors from escping nd keeps wter, dust nd debris from entering the tnk.

41 Chpter 3: Tnk System Bsics Monitoring Wells Monitoring wells re used to detect relese within the tnk bckfill, or the buried mteril surrounding n UST. Monitoring wells for lek detection re not common but you my hve one t your fcility. It is importnt to locte nd properly mrk your monitoring well to ensure product is not ccidently delivered to it. Monitoring wells should be pinted white, with blck tringle. It is importnt tht the wells re secure nd hve locking cps. A monitoring well without cp or cover cn llow contmintion or product to flow directly into the soil or groundwter. Monitoring wells cnnot be used s lek detection method where there is history of spills or site contmintion.

58 dsfsdf CHAPTER 7.0 Overfill Prevention Opertors nd drivers shre the responsibility of ensuring tht overfills or spills do not hppen during fuel deliveries. The best wy to prevent overfills is to deliver the proper mount of product. Before the delivery begins, the driver should determine how mny gllons of product cn sfely be delivered to the tnk. The delivery driver must only deliver enough product to fill the tnk to its working cpcity, which is typiclly 90 or 95% of the tnk volume. The portion of the tnk tht is unfilled t the strt of delivery is often referred to s the ullge. Mny utomtic tnk guging systems will indicte the mount tht cn be sfely delivered s the 95% ullge of the tnk. Why not 100%? Becuse if your tnk is 100% full before the tnk truck comprtment is empty, the driver will be left with hose full of fuel nd nowhere to drin it. Overfills occur when there is not enough room in your tnk for the remining product. Additionlly, fuels cn expnd due to temperture chnges, resulting in relese from 100% full tnk. Spills to the environment could result in potentil contmintion of soil or wter, or could even strt fire. Tnks must be equipped with utomtic lrms or other pproved devices to wrn the driver or to stop the delivery before n overfill occurs. Overfill Prevention Requirements 6 NYCRR (b)(3) 7 A/B Must prevent spilling nd overfill when petroleum is being trnsferred to the UST System Must prevent spills when trnsfer hose is detched from fill pipe Figure 7.1 shows driver prepring to mke fuel delivery.

It delivers premium product through n inner hose nd returns vpors to the truck vi n interstitil spce. Elbow fittings on the end of the green hose nd closest pink hose crete liquid tight sel to the tnk fill pipes.

59 dsfsdf Chpter 7: Overfill Prevention Opertor s Responsibilities to Prevent Delivery Overfills You should confirm tht your fuel supplier hs written delivery procedure for their drivers. Alterntively, you my provide written procedures nd require drivers to follow them. In ddition you MUST: Monitor ll fuel deliveries from beginning (either opertor or crrier) to end. Physiclly monitor your delivery drivers or focus security cmer on your fuel-delivery re. Inspect spill buckets routinely Inspect your spill buckets routinely for presence of product or wter, s well s crcks, worn sels, etc. See Chpter 13 for more informtion. Respond to ALL overfill indictions. Never ignore overfill lrms or fuel flow shut-off. Report nd clen up ll spills. Hve spill clen-up mterils hndy during ll fuel deliveries. Post emergency phone numbers in prominent loction for reportble spills. Report spills to the proper uthorities. See Appendix A for smple emergency phone number templte. Shut-off vlves must be mintined. Wht Do Overfill Prevention Devices Do? You re the primry overfill prevention device! You re responsible for seeing tht your tnks re equipped with proper overfill prevention devices nd tht delivery personnel follow proper procedures. An overfill lrm will lert the delivery driver tht the tnk hs reched the working cpcity but, if ignored, will not prevent n overfill. Other overfill prevention devices either stop or limit the flow of product into the tnk BEFORE the tnk is filled to the very top, so tht product left in the hose will still fit into the tnk. You re required to hve n overfill prevention device tht will perform one of these three functions: utomticlly shut off flow into the tnk when the tnk is no more thn 95% full; lert the opertor or driver when the tnk is no more thn 90% full by restricting flow into the tnk or triggering high-level lrm; or restrict flow 30 minutes prior to overfilling, or lert the opertor or crrier with high-level lrm one minute before overfilling.

60 dsfsdf Chpter 7: Overfill Prevention The two most common overfill prevention devices used to perform the functions bove re: electronic lrms; mechnicl overfill devices (bll flot vlves, shut-off vlves). Wht is Exempt? A fcility is not required to use spill or overfill prevention devices on UST systems tht re only filled by trnsfers of 25 gllons or less t time. 7.1 Mechnicl Overfill Device Automtic Shut-off Vlves Automtic shut-off vlves (lso known s flpper vlves) re instlled in the tnk s drop tube. The drop tube is thin luminum tube locted inside the tnk s fill pipe tht extends to the bottom of the tnk. A flot-ctivted flpper slms shut nd restricts flow to the tnk when the liquid level in the tnk reches 95% of the fill tnk volume. The delivery hose then jumps, lerting the driver tht the flpper hs been closed. The driver should immeditely stop the flow of fuel from the truck nd drin ny excess fuel from the hose into the tnk. Drivers need to be wtching the delivery hose in order to notice this jump. Shut-off vlves work well s long s they re instlled correctly nd mintined properly. The most common issues with shut-off vlves re: Shut-off vlves hve moving prts tht cn brek. Test your shut-off vlve nnully. Shut-off vlves must not be disbled or bypssed. Never leve guging stick or other item in your fill pipe. Such items cn keep your shut-off vlve from closing properly. Cll your service technicin to check your shut-off vlve if you find n item stuck in your drop tube. Do not llow deliveries to tnk with the shut-off vlve jmmed open. The sudden closing of the drop tube will put stress on the delivery system. The hose connections to the tnk nd the truck must be secure or they my disconnect, cusing surfce spill. The connection between the tnk nd the delivery hose MUST be liquid tight. Deliveries must be mde by grvity only.

61 dsfsdf Chpter 7: Overfill Prevention Bll Flot Vlves ( (b)(3)(i)(b)(2)) A bll flot vlve is contined in short piece of pipe tht extends into the top of the tnk where the vent pipe or Stge I vpor recovery exits the tnk. You might find it extremely difficult to determine whether or not your UST hs this device becuse it is not redily visible. Typiclly, bll flot vlve consists of wire cge contining hollow bll. The cge is fstened to the lower end of the vent pipe. The bll sits below the end of the pipe inside the wire cge. As the product level in the tnk rises, the bll flots up on the rising liquid. The bll will eventully block the vent opening if the level of the product gets too high. With the vent opening blocked, very little fuel cn enter the tnk. For bll flot to prevent n overfill, the tnk must be ir-tight nd the delivery hose must be tightly clmped onto the fill pipe. The working cpcity of tnk equipped with bll flot vlve should be set t no more thn 90% of the design cpcity. Bll flot vlves re NOT user friendly. They increse the pressure in the tnk, sometimes cusing fuel to splsh bck onto the driver if he/she tries to disconnect the hose. Drivers often try to relieve the pressure by opening the drin in the spill bucket or the cp of the utomtic tnk guge. These fittings re NOT DESIGNED to be opened during delivery. Doing so cn relese flmmble vpors, which cn cuse n explosion. The Petroleum Equipment Institute (PEI) recommends bll flot vlves NOT be used t ll. See the PEI link in Chpter 20.0 for more informtion. The following issues my led to extremely hzrdous conditions when using bll flot vlve: Deliveries should be mde by grvity only. Bll flot vlves re not designed to be used with pressurized deliveries. Figure 7.4: Bll Flot Vlve Fill connections must be tight. If the fill connection is not tight, fuel will bck up in the fill pipe nd result in spill on the ground when the bll flot vlve closes. Bll flot vlves should not be used for genertors or heting oil tnks. These tnks often hve loose connections or fill vi pumped (pressurized) delivery. Bll flot vlves my cuse product to escpe through remote fills nd guge openings. Bll flot vlves re NOT user friendly 7-4 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

62 dsfsdf Chpter 7: Overfill Prevention Bll flot vlves perform poorly in suction piping systems. When bll flot closes, the fuel in the tnk pressurizes nd looks for n escpe route. Dispensers re the most common escpe routes nd n overfill cn occur through dispenser ner your customers. Coxil Stge I vpor recovery systems render the bll flot useless becuse the recovery port llows the tnk to keep venting. Note: It is illegl nd unsfe for tnk to be equipped with both n utomtic shut-off vlve AND bll flot vlve. Hving both of these devices is NOT llowed. A bll flot vlve will interfere with the opertion of the utomtic shut-off vlve if it ctivtes before the shut-off vlve closes. 7.2 Electronic Overfill Alrms Electronic overfill lrms re the most verstile of the overfill prevention technologies. They cn be used with tnks tht hve tight or loose-fill connections nd receive either grvity or pumped (pressurized) deliveries. Never ignore overfill lrms Most overfill lrms re tied to n utomtic tnk guging (ATG) system by mens of probes/sensors. One such probe is locted inside the tnk nd hs flot tht rises s the tnk is filled. Typiclly, n lrm is triggered when the tnk is 90% full. The lrm cn be seen or herd or both. An overfill lrm should be locted outdoors ner the fill re nd be clerly lbeled so the driver knows when the tnk hs reched its working cpcity. When the lrm sounds, the vlve t the truck must immeditely be closed nd the contents of the delivery hose drined into the tnk. When n overfill lrm ctivtes often, DO NOT ignore it. A frequent Figure 7.5: Electronic overfill lrm overfill lrm my men there is something wrong with the delivery procedure or your tnk. The working cpcity of the tnk my be less thn you think it is. Cll your service provider to verify the overfill lrm settings re correct nd mtch the working cpcity of your tnk. Mny overfill lrms re equipped with test button. The lrm must be tested monthly to ensure the udible nd visul lert mechnism is operting properly. 7-5 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

63 dsfsdf Chpter 7: Overfill Prevention The most common issues with electronic overfill lrms re: Automtic tnk guging systems must be progrmmed for the correct tnk nd tnk chrt to ensure the correct working cpcity is used. The system power must be on. If the power to the overfill lrm or the ATG is turned off the delivery driver will not be wre of n overfill. If the lrm is equipped with test button, the delivery driver should test the lrm prior to delivering product to the tnk. Mny sites hve severl tnks nd one lrm. Once the lrm is ctivted, it will remin on while delivering to ny dditionl tnks.

64 dsfsdf 8.0 Inventory Monitoring Inventory monitoring helps you trck how much product is going into your tnk nd how much is coming out. Trcking gllons in nd gllons out versus how much is in the tnk will help you detect missing product nd possible leks. If your tnks store motor fuel or kerosene, nd if ny mount of tht product will be sold s prt of commercil trnsction, then you must perform 10-dy inventory reconcilition. You must ALSO meet the lek detection requirements outlined in Chpters 9.0 nd If you hve tnks tht store other types of product, or product tht is only used onsite, you my use 10-dy inventory reconcilition s n extr lek detection mesure. Ten-dy inventory reconcilition includes five importnt steps: 1. Tke dily mesurements of the product in the tnk. This mesurement is usully clled the stick reding even if you use n electronic guge insted of stick. Also mesure the totl gllons of product dispensed from the tnk (totlizer redings) nd gllons of product delivered to the tnk. 2. Clculte the dily difference ( vrince ) between the product level clculted from your totlizer nd delivery receipts, nd the product level you ctully mesure. 3. Clculte the sum of dily vrinces t lest every 10 dys. 4. Compre the sum of dily difference to llowble vrinces t lest every 10 dys. 5. Rect to vrinces nd investigte possible leks. Inventory monitoring trcks ll the chnges to the mount of product in your system, from delivery to dispensing. It llows you to identify leks from mny different components of your UST system.

65 Chpter 8: Inventory Control 8.1 Dily Inventory Monitoring Wht To Do Ech Dy Ech operting dy you must record the volume/mount of: petroleum delivered; petroleum dispensed; petroleum remining in tnk; nd wter (if ny) in tnk. Tke seprte inventory mesurements for ech UST t your fcility. Collect the tnk level redings nd the dily sles dt t the sme time. These steps will ensure tht no sles or deliveries re missed. You only hve to record these mesurements on dys you receive or dispense product. At fcilities where the site does not dispense or receive product for dy or more during given 10-dy period, you should stick the tnk t the end of the lst operting dy before the shut-down period nd t the beginning of the first dy fterwrds. Ech intervening dy should be crossed out on the reconcilition spredsheet (not filled out with zeroes, which might be interpreted s mesurements). Mesuring the Product Level with n Electronic Monitoring System An utomtic tnk guging (ATG) electronic monitoring system is designed to tell you wht s going on in your tnk system. Along with monitoring your tnks for leks, the system my tell you the product level, volume, nd temperture; wter level nd volume; nd high nd low level product wrnings. A typicl monitoring console is shown in Figure 8.1. Your ATG monitoring system must be ble to mesure both product nd wter level in your tnk. It must be ccurte within 1/8 to be used for inventory monitoring. Mke sure your ATG system hs been clibrted for the tnk t your site nd hs been progrmmed using your specific tnk s tnk chrt. A good wy to check to see if your ATG hs been progrmmed correctly is to tke the product height on your inventory report nd find the volume of product (in gllons) using your tnk chrt. The volume you find from your tnk chrt should mtch the volume on your inventory report.

66 Chpter 8: Inventory Control Some systems cn be progrmmed to utomticlly perform 10-dy inventory reconcilition, but this requires the system to interfce with the dispenser. You cn check with your service technicin to see if your system cn do utomtic reconcilition. Mesuring the Product Level Using Guging Stick You cn mnully mesure the product level in your UST using guging stick. Guging sticks re long wooden sticks with height mesurements mrked on them. For ccurte mesurements nd to meet the requirements in the regultions your guging stick must be: stright unbroken without wer or dmge on the bottom mrked in 1/8 increments mrked with legible numbers. To tke product level reding, lower the stick gently to the bottom of the tnk. Be sure to keep the stick verticl nd try not to touch the sides of the riser. Do NOT bounce the stick on the tnk bottom. Remove the stick from the tnk nd locte the line where the stick is wet. Record the number in inches to the nerest 1/8. Figure 8.2 shows proper technique for using tnk guging stick. Sites where tnks re not stuck to the nerest 1/8 cn expect to hve significnt inventory vrinces, nd the results will not meet regultory requirements. Guging sticks must be clerly legible nd in good condition. Do NOT use guging stick tht is broken or rounded on the end. Your tnk guging stick my hve Teflon button t the bottom. If the button is missing your stick is not the correct length. Using stick tht is not in good condition will cuse serious problems with your inventory records. Figure 8.3 nd Figure 8.4 show tnk guging sticks tht should NOT be used for inventory monitoring.

A smple 10-dy inventory reconcilition worksheet nd instructions is vilble in Appendix B. Mesuring Wter in the Tnk The best wy to mnully mesure wter in your tnk is by using wter-finding pste (lso known s wter pste) on your guging stick. Most gsoline tody contins ethnol, so be sure to use pste tht is comptible with ethnol-blend gsoline. If you hve different product t your site mke sure you use wter finding pste tht is comptible with your product. Follow the pste mnufcturer s instructions, pying prticulr ttention to how long the pste needs to sty in the tnk nd to wht color the pste will chnge (Figure 8.7). Record the height of wter, to the nerest 1/8, on your inventory reconcilition report. Electronic monitoring systems my hve wter sensor to detect wter in tnks. Confirm tht the wter sensor is instlled nd working properly before you rely on your ATG to detect wter in your tnks. Be sure to confirm tht the wter sensor is comptible with the product you re storing. Figure 8.7: Tnk guging stick with wter-finding pste. This brnd turns red to indicted wter level in the tnk.

71 Chpter 8: Inventory Control Your dily vrince will rrely, if ever, be zero becuse the mesurements you re tking re not exct. HOWEVER, your dily vrince shouldn t be too lrge. If you hve lrge dily vrince nd it is not mth error, PAY ATTENTION - your fcility my hve lek. If your totl vrince is lrger thn your llowble vrince nd cn t be explined within 48 hours by mth error, or some other reson tht isn t relted to lekge, then you must notify DEC. Wht To Do If You Hve A Blended Mid-Grde Product Some dispensers blend low- nd high-grde product to mke mid-grde product. You must record sles of these products correctly on your dily inventory. You cn use the blend rtio to determine how much of ech product is dispensed for ech gllon of mid-grde product. For exmple, site tht combines 87 octne nd 93 octne to dispense 89 octne would hve blend rtio of 60% (87 octne) product nd 40% of 93 octne. In other words, for every 100 gllons of mid-grde sold, there re 60 gllons of 87 octne nd 40 gllons of 93 octne. Be sure you re using the correct blend rtio for your site bsed on the octne rtings of ech product. Using the wrong blend rtio cn give incorrect inventory results. Be sure tht you re using the correct blend rtio if your dispensers blend fuels. Wht To Do If You Hve Siphoned/Mnifolded Tnks Some fcilities hve tnks with siphon between the tnks, or hve tnks tht with mnifolded fill pipes (see Chpter 3 for more informtion). The stick redings for ech tnk should be tken t the sme time, but recorded seprtely. Often, the stick redings will be within n inch or two of ech other. If your tnks hve different sizes, be sure to use the correct stick reding for ech tnk or it could ffect your inventory results. When two tnks re siphoned or mnifolded together, the inventory, sles nd deliveries will be combined. 8.2 Wht To Do At Lest Every 10 Dys Check the Totl vs. the Allowble Vrince At the end of ech 10-dy inventory reconcilition period you must compre your totl gllons delivered, totl gllons pumped, nd totl tnk volume to see which of these vlues is the lrgest.

Stick reding recorded to nerest 1/8 : Are you recording your tnk redings to the nerest 1/8? Siphoned/mnifolded tnks: Mke sure your siphoned or mnifolded tnk inventories re recorded correctly. If siphoned system hs two different tnk sizes, be sure tht the correct stick reding is used for ech tnk. Tnk guge clibrtion: If you re using n electronic monitoring system, you need to check to mke sure your tnk guges re clibrted correctly. Dispenser meters (totlizers): Check tht your dispenser totlizers re clibrted nd re working correctly. Mth errors: Check for mth errors. If you re using spredsheet, check the formuls in your cells to mke sure they hven t been ccidentlly chnged. Proper totlizers re used for ech product: If your pumps dispense multiple products mke sure you re reding the gllons dispensed off the proper totlizer. Confirm blend rtios: Confirm the mount of high-grde nd low-grde product you re blending to crete your blended mid-grde gsoline. Confirm electronic monitoring system mtches tnk chrt: Electronic monitoring systems should be clibrted ccording to your tnk chrt.

If you hve ny unexplined discrepncies in your inventory report, this is considered possible/suspected lek nd must be reported. You must notify DEC within 48 hours if the discrepncies cnnot be explined. Report evidence of possible lek to the DEC spill hotline: (or outside New York stte) Suspected leks must be reported within 48 hours Lek Investigtion nd Confirmtion Steps All leks must be investigted by one of the following methods: System (tightness) test or Site check Investigtions must strt within 48 hours of reporting suspected lek. The investigtion must be completed within 7 dys of strting the investigtion. See Chpter 9 for more informtion on lek detection nd confirmtion steps. 8.4 Recordkeeping Any suspected leks must be reported. Your 10-dy inventory reconcilition worksheets must be kept for 3 yers. The following must lso be mintined for 3 yers: results of ny smpling, testing or monitoring; written documenttion for ll clibrtion, mintennce nd repir of lek detection equipment; nd mnufcturer s schedules for clibrtion nd mintennce of lek detection equipment following instlltion.

It llows you to identify leks from mny different components of your fuel system. The relibility of inventory informtion is only s good s the cre you tke in your mesurements nd clcultions New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

77 Chpter 8: Inventory Control Inventory reconcilition must be done every 10 dys. Your totl vrince must be less thn the llowble vrince. If it is greter thn the llowble vrince, you hve to be ble to explin this discrepncy. If you cn t explin it, cll the DEC Spill Hotline. Your electronic monitoring system must be ble to mesure both fuel nd wter level in your tnk. It must be ccurte within 1/8 to be used for inventory monitoring. Mke sure your ATG hs been clibrted for the tnk t your site nd hs been progrmmed using your specific tnk s tnk chrt. For mnul mesurements, your guging stick must be clerly legible nd in good condition. Sites tht do not stick the tnks to the nerest 1/8 cn expect to hve significnt inventory vrinces, nd the results will not meet regultory requirements. The best wy to mnully mesure wter in your tnk is by using wter-finding pste on your guging stick. Be sure to use pste tht is comptible with your product. Whether you find the number of gllons pumped from your totlizer or from your point of sle system your meters need to be properly clibrted. The number of gllons dispensed must be metered nd recorded to n ccurcy of 6 cubic inches for every 5 gllons of product withdrwn. The delivery receipt should indicte both net nd gross delivery volume. Use the gross volume s the number of gllons delivered for inventory monitoring clcultions. The net volume is corrected for temperture nd should NOT be used for inventory monitoring. When two tnks re siphoned or mnifolded together, the inventory, sles nd deliveries will be combined. Be sure your clcultions use the correct blend rtio for blended products. Using the wrong blend rtio cn give incorrect inventory results. If your vrince is too high but the discrepncy cn be explined, you must dd your explntion to your inventory report. The inventory t your site should be consistent. If your site hs mjor dily or ten-dy totl vrinces, investigte the cuse. Do not expect bounce bck correction to occur. You must report ny leks or suspected leks to DEC.

78 dsfsdf CHAPTER 9.0 Tnk Lek Detection Ech of your underground storge tnks must be monitored for leks by t lest one method. The regultions llow for severl different types of lek detection, depending on the dte your tnk ws instlled (see Tble 9.1). The lek detection system for ech tnk must be listed on your fcility registrtion ppliction, nd cn be found on your Fcility Informtion Report (see Chpter 4). The piping must hve its own lek detection listed on system, s discussed in Chpter It is importnt to remember tht the requirements for piping lek detection re seprte from the requirements for tnk lek detection. Tnk lek detection systems must be ble to detect lek from ny portion of the tnk tht routinely contins petroleum. Any monitoring system used for lek detection must be instlled nd clibrted in ccordnce with the mnufcturer s instructions. Any tnk without properly functioning lek detection system must be tken outof-service. The registered method of lek detection cn be found on your fcility registrtion (see Chpter 4). Although you re only required to hve one method of lek detection, you my register more thn one method. For exmple, fcility could be registered with interstitil monitoring s well s utomtic tnk guging. If your registrtion indictes more thn one registered method of lek detection, EACH method of lek detection MUST be monitored, mintined nd documented. Lek Detection 6 NYCRR A/B NEVER ignore lrms. Suspected leks must be reported to DEC. You must check your tnks for leks nd record lek test results t lest once week. You must keep your lst 30 dys of lek detection records onsite. The opertor of ny tnk tht contins ny mount of motor fuel or kerosene tht will be sold s prt of commercil trnsction must lso conduct inventory monitoring for tht tnk, s discussed in Chpter 8.0. Indictions of lek should not be ignored. If your lek detection system indictes potentil lek, you must immeditely investigte the cuse of the lrm nd determine if the system is leking. Suspected leks must be reported to the DEC. The opertor must report suspected lek within the required time frme (see Section 9.6).

79 Chpter 9: Tnk Lek Detection To determine wht kind of lek detection method is permitted for your tnks, first see Tble 9.1 below to identify the ctegory of ech tnk. This chpter describes cceptble methods of lek detection for ech tnk ctegory. Tble 9.1 Tnk Ctegories Tnk Ctegory Instlltion Dte Ctegory 1 Before December 27, 1986 Ctegory 2 From 12/27/86 through October 11, 2015 Ctegory 3 After October 11, Lek detection for Ctegory 2 nd 3 Tnks Ctegory 3 tnks MUST be double-wlled. Ctegory 2 tnks MUST be double-wlled OR hve nother permitted method of secondry continment. Ctegory 2 nd 3 double-wlled tnks MUST be monitored by interstitil monitoring. Alterntive types of secondry continment for Ctegory 2 tnks MUST be monitored by n pproprite method. Monitor the interstitil spce nd ddress ll lrms in order to promptly detect fuel leks into environment, should they occur. Interstitil Monitoring Double-wlled tnks hve n interstitil spce between the primry (inner) tnk wll nd the secondry (outer) tnk wll. The interstitil spce cn be equipped with sensor/indictor to detect leks in the primry or secondry tnk nd my be either dry or wet type. Both types re normlly ccessed through mnhole in the tnk pd. It is importnt to understnd which type of interstitil spce is in your tnk. Figure 9.2: Wet interstitil spce A dry interstitil spce is not intended to contin ny liquid nd should be free of liquid t ll times. The presence of liquid in this spce is n indiction tht the primry or secondry tnk my be leking. Usully, dry interstitil spces re monitored with sensor tht detects the presence of liquid (product or 9-2 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

Any chnge in the pressure or vcuum level of the interstitil spce my indicte lek in the primry or secondry tnk. A wet interstitil spce contins liquid brine solution (slt wter). The brine solution is typiclly colored blue for esier detection. The interstitil spce is connected to reservoir where the brine level is monitored for ny gins or losses. If the brine liquid level rises or flls by more thn the mount specified by the mnufcturer (typiclly few inches) then either the primry or secondry tnk my be leking. The interstitil monitoring my be done either electroniclly or mnully. Electronic monitoring is done through n electronic monitoring console, while mnul monitoring cn be done using dipstick or pop-up indictor. Mnul results of interstitil monitoring results must be recorded t lest weekly. Where electronic monitoring methods re used, these systems must be inspected to ensure operbility t lest monthly. If the monitoring system goes into lrm, your tnk my be leking. Secondry Brrier Monitoring Secondry brrier monitoring is not permitted monitoring method for new tnks, but you my hve this system if you hve older Ctegory 2 tnks. Usully these tnks re single-wlled tnks instlled in pit tht is lined on ll sides nd bottom with hevy plstic liner (i.e., the secondry brrier) nd then filled with soil nd/or grvel. The secondry brrier is seled to the concrete tnk pd to crete n Figure 9.3: Tnk system with secondry brrier (shown in green) impermeble (liquid-tight) tub round the tnk. A monitoring well is used to monitor the spce between the tnk nd the brrier. Use of secondry brrier is subject to couple of requirements. The secondry brrier cn only be used for tnks locted bove the 25-yer floodplin. In ddition, the brrier must be comptible with the product stored. For exmple, the product cnnot cuse the liner to rot or dissolve. The brrier must lso not interfere with the cthodic protection system. 9-3 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

82 Chpter 9: Tnk Lek Detection Automtic Tnk Guging (ATG) Automtic tnk guging (ATG) systems cn be progrmmed to conduct periodic tests of your tnk system. During ech test, the ATG probe will mesure the product level nd the temperture over period of time. Your ATG probe must be cpble of detecting 0.2 gllon per hour (gph) lek rte with 95% probbility of detecting lek. It must lso hve no more thn 5% probbility of flse lrm. As n opertor, you must determine if the equipment used to conduct test meets the lek rte requirement. You cn determine if your ATG meets the requirements by checking whether it is listed by the Ntionl Work Group on Lek Figure 9.5: Typicl ATG schemtic Detection Evlutions (NWGLDE). NWGLDE listed systems meet the requirements. A link to the NWGLDE website is provided in Chpter You cn lso hve your tnk contrctor check whether your system meets the lek threshold requirements. Specil considertions my pply to mnifolded systems. For instnce, if your tnks re connected by siphon system, then your ATG system must be progrmmed to tret the siphoned tnks s single, lrge tnk. There re two types of ATG lek detection tests: sttic or continuous. Sttic Tests re conducted over period of time (bout 2 hours) during which the sttion does not dispense fuel or receive delivery. The ATG is usully progrmmed to test the tnk overnight while the fcility is closed. Be sure the time of dy is set correctly on the ATG so tht the test does not occur during the dy or when the system is in opertion. Figure 9.6: Exmple of n electronic monitoring console Continuous In-Tnk Lek Detection System (CITLDS) Tests re conducted while the fcility is operting. This type of test conducts product level nd temperture mesurements throughout the dy whenever the system is idle. If you hve CITLDS system, typiclly the system is progrmmed to report pss/fil test result t the end/beginning of ech dy. This type of test is lso known s Continuous Sttisticl Lek Detection (CSLD) test. 9-5 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

83 Chpter 9: Tnk Lek Detection For either type of test, the tnk must contin minimum volume of product. The minimum volume depends on your tnk nd on the type of ATG you hve. You must be sure tht the tnk is sufficiently full tht the test will be ble to check ll prts of the tnk tht routinely contin product. You or your service technicin must verify tht these requirements re met. In ddition, you must hve pssing test ech week (for either method). You cn use the form in Appendix D to record the results of the test. Become fmilir with the ATG t your fcility. Know wht type of test the ATG performs nd when the tests re scheduled. You should lso lern how to conduct n dditionl test t ny time. Your ATG console should be ccessible AT ALL TIMES. You need to be ble to see or her lrms. You lso need to be ble to record test reports, usully by printing them out or writing them down. Keep the re round your console cler.

Mnul Tnk Guging Figure 9.8: ATG console with n overfill lrm. The print out will indicte which lrms re current nd need to be ddressed Mnul tnk guging (MTG) is bsed on mesuring product levels with guging stick. The test cn tke from 36 to 58 hours, depending on the size of the tnk. The tnk cnnot dispense or receive product during the test. Note: While this method seems similr to the process for inventory monitoring, it is NOT THE SAME; the only similrity between the two is tht both use guge sticks. Mnul tnk guging is lek detection method; inventory monitoring is not. This method cn ONLY be used for: Tnks less thn 550 gllons; or Tnks 550-1,000 gllons with dimeter of 64 inches or 48 inches. You will need: A tnk guging stick. The stick must be legible, in good condition, nd ccurte to 1/8 ; nd A tnk chrt tht shows the volume of your tnk vs. height of product. The chrt must be ccurte to 1/8. To mnully guge tnk you must mesure the product level in the tnk nd then leve the tnk undisturbed for certin length of time (see Tble 9.2). At the end of the test period you must mesure the Figure 9.9: Mesuring the mount of product in the tnk 9-7 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

Figure 9.11: Groundwter monitoring well Vpor Monitoring Vpor monitoring tests the vpor in the soil through monitoring wells round your tnk for ny significnt increse in concentrtion of product or trcers. Vpor monitoring relies on discovering product in the soil AFTER the tnk hs leked into the environment. This method of lek detection is not commonly used nd is not recommended. Vpor monitoring is NOT recommended s primry lek detection method. This method only works if the product is voltile enough to generte detectble vpor level, or if voltile trcer chemicl is dded to the product. Monitoring wells or vpor probes re plced in the soil round the tnk to monitor the soil vpor for product. The vpor monitoring system must be operble even in the presence of rin, groundwter or moisture in the soil for more thn seven dys. Bckground vpors must not interfere with the detection of leks from the tnk. The soil round the tnk must consist of grvels, corse to medium snds, course silt or other permeble mterils; otherwise, vpors my not trvel freely through the soil.

Pressurized Piping System: Pressurized piping systems re the most common fuel pumping method t retil motor-fuel opertions. A pressurized system hs pump, usully clled submersible turbine pump (STP), locted in the tnk. The STP will pump product from the tnk to your dispenser. If you hve pressurized system, you cn see the submersible pump hed when you look into your tnk top sump. Figure 10.3 shows sump contining submersible pump hed nd product piping. Submersible pumps operte under positive pressure. The high operting pressure mens tht leks in underground piping served by these pumps cn go unnoticed. This hppens becuse the system cts like grden hose with the fucet turned on full. Even if the hose hs smll holes in it, most of the wter still comes out the nozzle. If you only look t the nozzle, you cn t tell tht wter is lso leking out of the smll holes. But if you leve the fucet open for long time, wter sprying from the smll holes will eventully sok the ground. In much the sme wy, you cn t tell tht there re smll leks in pressurized underground piping just by looking t how fst product is dispensed. Over time, however, those smll leks of product cn contminte soil nd groundwter t your site. Leks from pressurized piping systems ccount for lrge number of underground product releses.

A suction pump tht will not pump or frequently loses its prime my hve line lek, fulty check vlve, or both. The type of lek detection tht is required for your tnks depends on the tnk ctegory nd on whether you hve pressurized or suction piping. You cn use the informtion bove, or check with your service technicin, to determine wht type of piping system you hve. Tble 10.1 will help you determine the ctegory of your tnks.

Pressurized Piping Systems Ctegory 3 nd New Piping Pressurized piping connected to Ctegory 3 tnk systems, or new pressurized piping connected to Ctegory 1 or 2 tnk systems, must hve TWO types of lek detection: n utomtic line lek detector (mechnicl or electronic); AND weekly interstitil monitoring of the tnk top sump (electronic or mnul). These lek detection methods re described below New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

95 Chpter 10: Piping Lek Detection Automtic Line Lek Detector Automtic line lek detectors (LLDs) cn detect leks in pressurized piping. Typiclly, LLDs re instlled on the submersible turbine pump (STP) hed in the tnk top sump. There re two types of LLDs: mechnicl nd electronic. Mechnicl LLDs (MLLDs) re mechniclly operted pressure vlves tht detect loss in piping line pressure ech time the pump is turned off. Mechnicl LLDs WILL NOT completely shut off flow to the pipe if they detect lek. A MLLD will not trigger n udible or visul lrm when lek occurs. The only wy to tell tht the MLLD hs been triggered is by noticing tht the fuel is now being dispensed t very slow rte. If your norml flow is round 7-10 gllons per minute (gpm) lek will be indicted by flow restricted to bout 3 gpm or less. A MLLD device is threded into the top of the submersible pump hed nd hs no wiring connections. The LLD my hve round or hexgonl top s shown in Figure 10.5 nd Figure Newer models will lso hve copper lines ttched. If you experience slow flow condition, the line lek detector my be indicting lek in the pipe. Investigte the system nd do not ignore the signs of lek. Common problems with mechnicl LLDs re listed below. Figure 10.5: Mechnicl LLD (Alsk DEC) Slow flow my be cused by conditions other thn leks, such s plugged filters or defective pump motors. Cll your service technicn immeditely to investigte the cuse of low flow. Cold tempertures overnight cn cuse mechnicl LLD to slow product flow first thing in the morning. If slow flow persists fter your first dispensing period, cll your service technicn. LLDs cn wer out. Mechnicl LLDs typiclly need to be replced every few yers. Figure 10.6: Mechnicl LLD (Alsk DEC) 10-4 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

96 Chpter 10: Piping Lek Detection Electronic LLDs hve n electronic detection element tht connects to n electronic control pnel nd monitors for releses by looking for pressure losses in the piping. Unlike mechnicl LLDs, electronic LLDs will completely shut down the submersible pump if they detect lek. The shutdown will usully pper s n lrm on your ATG console or other monitoring device. Typiclly, electronic LLDs check for leks of three gllons per hour, lthough some cn lso perform 0.1 or 0.2 gllon per hour test. An electronic LLD is threded into the submersible pump hed. It is connected to the pump electricl system nd is either hrd wired or wirelessly connected. Figure 10.7 shows n electronic LLD on submersible pump. Electronic LLDs re much more relible indictors of leks thn mechnicl LLDs. If your pressurized piping does not hve n LLD, then you must instll one. Figure 10.8 is n exmple of submersible pump with no LLD. If your submersible pump is not equipped with n LLD, you should contct your service provider to discuss retrofit options. Figure 10.7: Electronic line lek detector on submersible pump (EPA) Both mechnicl nd electronic LLDs must be designed to detect leks of three gllons per hour. You should check your records or check with your service provider to verify tht your LLD meets the three gllons per hour requirement. You re lso required to test your LLD every yer to ensure tht it is operting properly. Records from LLD tests must be kept for three yers. Figure 10.8: Submersible pump with no LLD Interstitil Monitoring for Double-wlled Piping Interstitil monitoring is the second lek detection method required for new pressurized piping systems. Remember from Chpter 3 tht double-wlled piping is primry pipe encsed inside secondry pipe. Between the two wlls is n interstitil spce. The secondry pipe is designed to keep ny leks from the primry pipe contined inside the interstitil spce. You must monitor the interstitil spce in your double-wlled piping for leks t lest weekly.

97 Chpter 10: Piping Lek Detection Leks into the piping interstitil spce will drin to liquid-tight sumps tht re typiclly locted where the piping connects to the tnk top (tnk top sump). Sumps re typiclly mde of fiberglss or polyethylene plstic. Figure shows tnk top sump with product from piping lek. Figure illustrtes typicl double-wlled piping system lyout. The piping slopes down from the dispenser to the tnk so tht leks from the primry pipe will drin down into the tnk top sump. Leks from equipment within the tnk top sump will lso be contined inside the sump. Leks from piping inside the dispenser cbinet will be contined in the under-dispenser continment (UDC) sump. Figure 10.10: Tnk top sump with product Some systems my lso include intermedite sumps, lso known s trnsition sumps. Intermedite sumps re typiclly instlled to brek up long underground piping runs. Leks from the primry pipe in these piping runs re contined in the intermedite sump. Double-wlled piping cn be monitored electroniclly or mnully.

98 Chpter 10: Piping Lek Detection Electronic Interstitil Monitoring is often used to monitor piping systems for leks. Mny systems, like the one shown in Figure 10.12, combine fuel level monitoring by the utomtic tnk guge (ATG) with continuous lek detection monitoring by lek sensors. Other systems my hve seprte console just for lek detection. This prticulr system hs sensors both in the tnk top sump nd in the UDC (Figure 10.13). The sensors will trigger n lrm t the console if liquid is detected in the sump or UDC. There re two different types of lek detection sensors: discriminting nd non-discriminting. Discriminting sensors cn tell the difference between wter nd product nd provide seprte lrm for ech liquid. Non-discriminting sensors, which re more common, only tell you whether liquid is present. You will need to look in the sump to determine if it is product or wter. If visul determintion is difficult, you my find it helpful to test the liquid with sorbent pds tht bsorb only oil. Sensors must be instlled in ccordnce with mnufcturer s instructions, which typiclly stte tht sensors must be instlled verticlly, with the bottom of the sensor within one inch of the bottom of the sump. Sensors should be tested ech yer to ensure they re in good working condition nd re operting correctly. Become fmilir with your monitoring console nd understnd the lrm messges. Figure 10.12: Electronic monitoring console in lrm Tip: Keep list of ll the sensor loctions with the sensor identifiction number posted close to your ATG console or relese detection console. This will llow you or your service technicin to esily locte which prt of your piping system is cusing the lrm.

99 Chpter 10: Piping Lek Detection Common problems with electronic interstitil monitoring: Wter is present in the tnk top sump. If you hve frequent lrms due to wter in your tnk top sump, tlk to your service technicin bout options to fix the problem. Sumps re not liquid tight. Leks from your sumps cn llow product to escpe into the environment before the sensors detect them. It is recommended prctice to test your sumps periodiclly to mke sure they re still liquid tight. Schrder vlves re closed. Schrder vlves re similr to the vlves used to fill tires. They re typiclly instlled where double-wlled piping trnsitions to single wlled piping. Two Schrder vlves, which my be connected with plstic tubing, close off the interstitil spce. These vlves should ONLY be connected during tightness testing of the double-wlled pipe. They must be opened or removed during norml opertion in order for leks to be detected. If the Schrder vlves re not opened or removed, leks from the primry piping will be trpped inside the interstitil spce insted of flowing into the sump. This will prevent your sump sensors from triggering the lrm when you hve lek. To keep your system operting properly, you MUST open the Schrder vlves nd disconnect tubing between the vlves during norml opertion. This will llow leks to rech your sump sensor nd trigger your wrning lrm. If either your ATG console or lek detection console is in lrm tke the following steps: Visully inspect ll sumps to determine if product is present. Stop dispensing product until the lrm cn be identified nd corrected. Shut off power to the submersible pump to prevent dditionl releses to the environment. Otherwise, the submersible pump will pressurize the line ech time dispenser is used, potentilly cusing dditionl product to be relesed into the environment. Never ignore piping lek detection lrms on your ATG console. Contct your service technicin immeditely to determine the cuse of the lrm. Hve tightness test performed on the piping. Report ny lrms or the presence of fuel or wter in sumps within 2 hours to the DEC (see Chpter 14 for more informtion bout reporting leks). Mnul Interstitil Monitoring must be performed if you do not use n electronic monitoring system. To conduct mnul interstitil monitoring you must open ech sump weekly to visully inspect for wter or fuel.

If you discover wter in your sump, you should remove nd properly dispose of the wter, then dignose nd fix the cuse of the wter intrusion. Suction Piping Systems Ctegory 3 nd New Piping It is reltively esy to tell if suction piping system hs hole in it becuse it will not operte properly. The pump my mke unusul noises when it is first turned on nd it will tke longer thn usul for product to come out of the nozzle. These symptoms re cused by ir entering the hole in the pipe, known s losing the prime. Loss of prime could lso be the result of fulty check vlve. Suction piping systems hve check vlve to keep the piping nd pump full of liquid when the pump is turned off. The check vlve is one-wy vlve tht Figure 10.14: Suction system dispenser opens whenever product is flowing through the dispenser nozzle, nd closes utomticlly when the pump is turned off, in order to keep product from flowing bck to the tnk. You must monitor your suction piping, using permitted lek detection method, UNLESS the system is designed to meet ALL the following sfe suction (lso known s Europen suction) criteri: The underground piping opertes t less thn tmospheric pressure (i.e.: under suction); The underground piping is sloped so tht the contents of the pipe will drin bck into the tnk if the suction is relesed; there is only one check vlve in ech suction line; the check vlve is locted directly below nd s close s possible to the suction pump (directly under the dispenser).

Automtic line lek detectors work for Ctegory 1 nd 2 systems in the sme wy s for Ctegory 3 systems (see Section 10.2). Interstitil monitoring is conducted for Ctegory 1 nd 2 systems in the sme wy s for Ctegory 3 systems (gin, see Section 10.2). Vpor monitoring nd groundwter monitoring re not recommended piping lek detection methods. If you use one of the other weekly monitoring methods, monitoring must be conducted for ll portions of piping tht normlly contin petroleum. The permitted lterntives include the following: Vpor monitoring Groundwter monitoring Sttisticl inventory reconcilition (SIR) Vpor monitoring, groundwter monitoring, nd SIR re described in Chpter 9. Groundwter nd vpor monitoring rely on discovering product in the groundwter or soil AFTER product hs leked into the environment nd re difficult to implement for piping lek detection.

106 dsfsdf CHAPTER 11.0 Cthodic Protection (Corrosion Protection) Cthodic protection (CP) - lso known s corrosion protection - pplies to steel tnk systems nd steel piping. Without cthodic protection, underground metl tnk systems will corrode (rust) nd my lek product into the environment. Corrosion cn ttck the steel uniformly or crete hole in smll, loclized re (see Figure 11.1). Loclized corrosion is the most common form of corrosion. Given the right environmentl conditions, loclized corrosion cn crete lek in n unprotected tnk or pipe in very short time. It is YOUR responsibility to mintin your CP system so tht your UST system remins protected from corrosion. Cthodic Protection 6 NYCRR (b)(1) nd ( (b) 11 A/B Mintin your CP system to prevent leks New York s PBS regultions stte tht underground steel components nd ny other UST system components tht re not corrosion resistnt MUST be protected ginst corrosion. Corrosion cn be prevented by: using non-metllic components such s fiberglss, coting the metl to isolte it from soil nd groundwter, nd/or using cthodic protection (CP) system. Certin non-metllic mterils, like fiberglss, do not corrode. Therefore, components mde from these types of mterils do not need CP. Note: A CP system only protects the outside of the tnk system tht is in contct with soil. CP does not protect ginst corrosion tht strts from the inside of your tnk, which often occurs due to wter in the tnk. It is importnt to keep wter out of your tnks.

107 Chpter 11: Cthodic Protection 11.1 Cthodic Protection Requirements Buried steel UST system components, including tnks or piping, tht routinely contin petroleum must be protected from corrosion. CP systems must be designed, fbricted nd instlled ccording to one of the codes of prctice listed in the PBS regultions. Every fieldinstlled cthodic protection system must be designed by corrosion expert. For the cthodic protection system to work correctly, tnks must be electriclly isolted from other metl objects unless the CP system is designed to lso protect the other metl objects. A cthodic protection tester cn determine if your system is electriclly isolted. All steel piping tht routinely contins petroleum nd is in contct with the ground MUST be cthodiclly protected. Cthodic protection for steel piping must: include pipe coting system mde of suitble dielectric mteril, be designed nd instlled ccording to the codes of prctice listed in the regultions, be designed by corrosion expert, nd be properly mintined nd operted, including required testing. Metl piping or fittings tht hve leked petroleum due to dmge or corrosion cnnot be repired, but must be replced. For piping systems tht do not meet new piping requirements, if 50% or more of piping run needs to be replced, then you must replce the entire piping run. The replcement piping must meet the stndrds in effect t the time of instlltion (including requirements for double-wlled piping, if pplicble). Non-corrodible pipes nd fittings my be repired in ccordnce with mnufcturer s specifictions Glvnic Systems Glvnic cthodic protection systems re the most common type of cthodic protection. They re reltively esy to instll nd mintin becuse they do not require connection to n electricl power circuit. In glvnic CP systems, scrificil nodes ttched to the tnk provide CP (Figure 11.2). Corrosion then occurs t the nodes insted of the tnk or piping. However, the system my fil over time s the nodes corrode wy. Therefore, these systems must be tested nnully by qulified corrosion tester.

108 Chpter 11: Cthodic Protection It is difficult to check whether you hve glvnic corrosion system becuse ll the components re buried. However, CP tester cn determine whether your steel tnks nd piping re: cthodiclly protected; receiving dequte levels of protection; nd electriclly isolted from other metl components such s electricl conduits Impressed Current Systems In contrst to glvnic systems, impressed current systems require n electric power source. These systems re typiclly connected through rectifier to the sme electric service s the pumps, dispensers, lights, etc. t your fcility. The rectifier powers buried nodes tht crete electricl currents to protect your steel tnks nd/or steel piping (see Figure 11.3 nd Figure 11.4 for exmples of rectifiers). The rectifier MUST be powered on t ALL times to properly protect your tnk from corrosion. Do NOT turn off the rectifier nd do NOT shut off the circuit breker it is connected to. Figure 11.3: Rectifier Most rectifiers re equipped with voltmeters nd mmeters to monitor system voltge nd electricl current/mperge (see figures). These redings will help you to determine if your system is operting properly. Voltmeter Ammeter 11.4 Inspection nd Testing All CP systems must be tested YEARLY by qulified CP tester.

If your redings re more thn 10% higher or lower thn the instlltion redings, then something is wrong with your CP system. Contct corrosion expert to check your system. To check for continuous opertion, you need to know how long the impressed current system hs been working. After recording the current totl hours, subtrct the previous totl from the current totl. Divide the number of hours by 24 nd compre to the number of dys since the lst reding. Note: 30 dys = 720 hours; 60 dys = 1440 hours. These numbers should be the sme. If they re not, determine the cuse nd correct it. Be sure tht fcility employees know tht they must not turn off the rectifier or the circuit breker tht controls it. If necessry, contct n electricin or CP technicin to repir the system. DO NOT ignore filing cthodic protection tests or 60-dy rectifier inspections! If your system fils CP test or rectifier inspection, you must repir the system immeditely. Without proper cthodic protection, steel tnks nd piping cn rpidly corrode nd relese petroleum to soil or groundwter t your fcility Repirs to Cthodic Protection Systems Eventully your CP system will need repirs.

In ddition to piping, dispensers my contin filters, pumps, multiple joints, nd vlves. Ech of these components is potentil site for leks to occur. Understnding the components of your dispenser nd performing proper mintennce cn help you prevent leks into the environment. Inspection nd mintennce of dispensers is your responsibility. You should visully inspect your dispensing equipment dily to ensure it is working properly nd lek free. Figure 12.1, Figure 12.3, nd Figure 12.2 show different types of dispensers tht my be present t your site. Dispensers come in mny different shpes, sizes nd colors but they re ll required to hve some of the sme fetures.

114 Chpter 12: Dispensers 12.1 Dispensing Equipment Pumps: Pressurized vs. Suction Systems Your dispenser is prt of either suction system or pressurized system. In suction system (see Figure 12.5), the system pump is inside the dispenser nd sucks product from the tnk. Motor Pump In pressurized system, the system pump is inside the Figure 12.5: Suction system dispenser tnk insted of inside the dispenser (see Figure 12.6) nd the pump pushes product to the dispenser. Suction nd pressurized systems must meet different regultory Figure 12.6: Pressurized system requirements, so it is importnt to know which type of system you hve. If dispenser you cn see pump nd motor inside your dispenser, you hve suction system. You cn lso listen when you ctivte the dispenser. If you cn her pump nd motor strt, then there is good chnce it is suction dispenser. Dispensers with Blended Products Some dispensers re tied to blending systems tht mix low- nd high-grde products from seprte tnks to crete midgrde product. These dispensers could hve one nozzle, similr to the dispenser shown in Figure Dispensers tht provide blended fuels my lso hve three different product nozzles. The blended mid-grde product is mixed inside the dispenser just before it is dispensed.

115 Chpter 12: Dispensers Piping Buried steel pipe connected to the dispenser must be protected from corrosion by n pproved protective coting nd/or cthodic protection (see Chpter 11). Alterntively, the piping my be routed through corrosion resistnt sleeve tht isoltes the piping from soil nd groundwter. Both ends of the sleeve must be protected from contct with soil Under-dispenser Continment Under-dispenser continment (UDC) or simply, dispenser sump - is designed to contin leks from the dispenser piping. The UDC sits beneth your dispenser s shown in Figure UDCs typiclly contin the following: vlves piping buried risers flex connectors sump sensor electricl conduit UDCs re required for ll new dispensers. Dispensers re considered new when both the dispenser nd the equipment needed to connect the dispenser to the UST Figure 12.8: View into UDC from the dispenser cbinet re instlled t fcility. The connecting equipment includes check vlves, sher vlves, unburied risers, flexible connectors, or other trnsitionl components instlled beneth the dispenser nd connected to underground piping. Figure 12.9 shows UDC before buril. Underground piping nd conduit enter the UDC where they trnsition to dispenser piping. UDCs my be mde of fiberglss, steel or HDPE plstic. When you open the door to your dispenser cbinet nd look inside, you should be ble to see your UDC. UDCs MUST be liquid tight on ll sides, on the bottom, nd t ny penetrtions (i.e. where the underground piping nd conduit enter the UDC).

Sher Vlves 12.3 Vlves Every dispenser tht is prt of pressurized piping system must be equipped with sher vlve, lso known s crsh vlve or impct vlve. When properly instlled, sher vlve tht meets NFPA 30A stndrds stisfies the regultory requirement. The sher vlve is designed to stop product flow from the pressurized pipe if your dispenser is dislodged or struck by vehicle. In order to stop product flow, the sher vlve must be locted in the supply line t the inlet of the dispenser. The vlve must be properly nchored nd instlled t the correct height (usully t grde). Figure shows sher vlve tht hs been properly nchored. You should hve your sher vlve inspected yerly. Figure 12.10: Proper sher vlve plcement Sher vlves must not be modified or tmpered with to keep them open. Figure nd Figure show sher vlves tht hve been tmpered with to keep them open. These vlves would not perform s intended in collision, nd would fil DEC inspection. Figure 12.11: Retrofitted sher vlve. This defets the sfety purpose of the vlve nd would fil DEC inspection.

Therefore, product continued to flow. The result ws dmging fire nd costly clen up. Figure illustrtes vehicle collision where the sher vlve closed properly. Product flow therefore stopped, nd no fire occurred. Figure 12.13: Accident where the sher vlve filed to shut off fuel flow. Figure 12.14: Accident where the sher vlve properly shut off fuel flow. Check Vlves A piping system is considered sfe suction system if it stisfies ALL of the following criteri: The piping opertes t less thn tmospheric pressure (i.e., under suction); it hs check vlve t the bottom of the dispenser; there is no other check vlve on the suction piping; AND the piping slopes down to the tnk. Sfe suction systems - lso known s Europen suction systems - re defined by the plcement of the check vlve (see Figure 12.15). The purpose of the check vlve is twofold. First, the check vlve keeps product flowing in one direction by preventing bckflow. Second, if the piping in sfe suction system springs lek, most of the product will likely flow bck into the tnk insted of through the lek into surrounding soil. If suction system stisfies the criteri bove, it does NOT require lek detection. You must be ble to show tht your sfe suction system hs only one check vlve, nd tht the vlve is properly locted. However, it cn be difficult to identify in-line check vlves. If you do not hve documenttion of your check vlve loction, service contrctor my be ble to investigte your system nd provide written report tht documents the vlve for your records New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

118 Chpter 12: Dispensers 2 1 Figure Digrm showing loction of check vlves for (1) Europen (sfe) nd (2) Americn suction system (Source: DEC) Some suction systems hve check vlve locted t the tnk, either ner the top of the tnk or t the bottom of the suction line in the tnk. This type of system is clled n Americn suction system. If the piping in this system leks, the product in the piping will be blocked by the check vlve nd will not drin bck into the tnk. Insted, the product will be relesed into the environment. Therefore, this type of system requires lek detection (see Chpter 10). If product is delivered to your tnk using pump (e.g. the on-bord pump of fuel delivery truck), nd if the fill pipe is rrnged such tht product could flow bck out of your tnk through the fill pipe, then you MUST hve check vlve on the fill pipe to prevent bckflow. Solenoid Vlves Grvity hed systems re fuel systems where the UST sits t higher elevtion thn the fuel dispenser. You my see this type of system, for exmple, t mny mrins (see Figure 12.16). If the dispenser or hose hs lek, grvity cn cuse product to flow from the tnk (up high) nd out the lek (down low). The product cn keep flowing until the tnk is empty, creting lrge spill t your fcility. To prevent this type of spill you MUST instll solenoid vlve, n ntisiphon vlve, or similr device, to keep the pipe closed off when you re not dispensing fuel. The solenoid must be instlled djcent to nd downstrem of the tnk s operting vlve (usully in the tnk top sump). A solenoid vlve tht meets NFPA 30A stisfies these requirements. Your tnks must hve operting vlves to control the flow of product through tnk connections 12-7 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

An operting vlve tht meets NFPA 30 stndrds meets this requirement. Brekwy Vlves The brekwy is locted on your dispensing hose. The purpose of brekwy is to prevent spills if customer drives off with the nozzle still in their fuel tnk. The brekwy will brek nd snp the hose shut to prevent product from escping from the dispenser. The brek occurs t the brekwy insted of shering the hose open. Some brekwys re designed so tht you cn reconnect the hose. Other kinds must be replced before you cn use the hose gin. In either cse, you should look over the interior nd exterior of the dispenser to mke sure the dispenser or sher vlve wsn t dmged during the incident.

Spill bucket nd their lids/plow rings should lso be inspected to ensure they crete wter tight sel. Any chips or crcks in the lid or plow ring will llow wter to enter the spill bucket. Crcks or holes in the spill bucket will llow wter or fuel to lek out. Dmged spill buckets must be replced. Most spill buckets re equipped with drin vlve. The drin vlve is locted t the bottom of the bucket nd when used, drins ny liquid contined in the spill bucket into the tnk. Fuel in clen bucket cn be returned to the tnk by opening the drin vlve. Figure: 13.4 Spill bucket nd hnd pump. If your spill bucket contins wter or fuel/wter mixture, the liquid must be disposed of properly. Contct your UST service provider for ssistnce in disposing this wste. Mny spill buckets either do not hve drin vlve or hve vlve tht hs been plugged to prevent wter from drining into the tnk. When the spill bucket does not hve functionl drin vlve, the opertor must hve method to remove the liquid from the spill bucket. This is often done using hnd pump. Double-wlled spill continment buckets cn lso be instlled.

You must conduct lek investigtion tht meets the requirements of 6 NYCRR (c) if 1. you suspect lek t your fcility, OR 2. your tnk system my be the source of impcts tht re observed by (or reported to) DEC on nerby property. Signs of environmentl contmintion on nother property include conditions such s the presence of free product or vpors in ny of the following: soil, bsements, sewers, utility lines, nerby surfce wter, or drinking wter. If lek or spill is suspected on your site or nother property, you must begin n investigtion within 48 hours nd complete it within 7 dys. Figure 14.7: Technicin performing tnk test If evidence of lek is not bsed on environmentl contmintion (e.g. equipment-bsed lrms or lek monitoring results), then you must do tightness test on your tnk system.

If the results of the tightness test do not indicte lek nd there is no evidence of environmentl contmintion, then no further investigtion is required. If the tightness test confirms lek, you must conduct site check s described below. A site check must lso be performed if the results of the tightness test do not indicte tnk lek but environmentl contmintion is the bsis of the lek investigtion. A site check requires the fcility to mesure for the presence of relese where contmintion is most likely to be present. You must consider the loction, methods of storge nd type of petroleum stored to be sure the investigtion cn identify the source of the relese. As n exmple, some sites my hve existing monitoring wells on site. These wells could be used to mesure for contmintion s long s the relese is likely to be discovered through those wells. Fcilities my need to instll monitoring wells or excvte the subsurfce to determine if the tnk system is leking. If the site check does not revel relese, further investigtion is not required. Be certin to document ny investigtion nd the results of the investigtion. If the site check does revel relese, the DEC must be notified within 2 hours fter the discovery. Lek investigtions must strt within 48 hours of reporting suspected lek. Respond immeditely to spills or leks. Identify nd mitigte ny fire or explosion hzrds during your initil spill response. A corrective ction my be required if relese hs occurred. Steps to develop nd implement corrective ction pln include: initil btement, site chrcteriztion, free product removl, investigtions for clen-up, nd pln development/implementtion. Initil Abtement Mesures ( ) Once relese is confirmed, you must perform the following initil btement mesures, unless directed otherwise by DEC. 1. Remove s much of the petroleum from the tnk system s necessry to prevent further relese. 2. Visully inspect boveground releses or exposed below-ground releses nd prevent further petroleum migrtion.

152 dsfsdf CHAPTER 17.0 Tnk System Comptibility Underground storge tnks nd piping systems my not be ble to sfely store ll types of petroleum products. With mny new blended nd lterntive fuels on the mrket, such s ethnol nd biodiesel, it is more importnt thn ever to verify tht your UST system nd components re comptible with the types of product stored t your site. Tnk system comptibility cn lso be problem when switching between types of product stored. Product tht is not comptible with your system my degrde your tnk, piping, sels, gskets nd other components of the equipment nd could result in product being relesed into the environment Definition of Comptibility Comptibility 6 NYCRR (c) 17 A/B Tnks, piping nd ll components of your UST system must be comptible with the product stored. All the components of the tnk system must be comptible with stored product. The mnufcturer certifies the product comptibility of the tnk system components. When product is used with system components tht re not comptible, it cn cuse the tnk, piping, or system components to rust, soften, weken, or otherwise degrde. Some blends of gsoline, such s ethnol blends, re more corrosive thn others, nd my require specil mterils or tnk linings to prevent the tnks from filing over time. Becuse there re so mny blends nd combintions of products, you must know which products re being delivered to your site. Wht is the percentge of ethnol or biodiesel? Hs the product delivered to your site chnged or re the products going to chnge? Contct your supplier for specific product informtion. Figure 17.1: Is your UST system comptible with the product you re storing? 17-1 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

153 Chpter 17: Comptibility 17.2 Why Does Comptibility Mtter? Use of UST system equipment to store incomptible products or blends is not permitted. Using incomptible equipment cn cuse equipment filure nd result in releses into the environment. Ethnol Ethnol hs corrosive effect on soft metls such s led nd glvnized zinc. It lso hs tendency to deteriorte or dissolve gskets, lcohol-bsed glues, selnts, fittings, O-rings, bushings, couplings nd boots in your UST system. The components of your UST system were built nd designed for certin level of ethnol in the product. Do not store higher ethnol blend thn your system is designed to store. Also be wre tht equipment tht is comptible with certin ethnol blends my not be comptible with ll other ethnol blends. You should confirm comptibility for your system before dding ny blends to your tnks (see Section 17.4, below). In ddition, system components such s overfill prevention nd lek detection my need to be clibrted for the specific ethnol blend you re storing, even if they re otherwise comptible with rnge of blend rtios. Ethnol cn lso cuse problems if wter enters your UST system. The ethnol in your fuel system will bond with wter. If enough wter is present in the fuel, phse seprtion of the fuel nd ethnol/wter mixture cn occur. The wter/ethnol mixture leves the fuel in the tnk without the proper ethnol blend. This reduces the octne of the fuel. Off-specifiction fuel is illegl to sell nd fuel mixed with wter cn dmge vehicle engines. Blends of gsoline, diesel nd other petroleum products frequently chnge. Smll mounts of wter cn enter your UST system through regulr tnk opertion nd mintennce, for instnce s result of condenstion of humid ir. If enough condenstion occurs to cuse mesureble ccumultion of wter in your tnk, you my hve serious problem. DO NOT ignore such ccumultions, since they re likely to indicte lrger problem tht my result in equipment filure or spills. Accumulted wter cn circulte through the piping system s well, becuse product is drwn off the tnk bottom, where wter ccumultes. If fuel is contminted with wter, then the piping system must be flushed out to ensure tht ll contminted product is removed. Contminted fuel nd/or wter must be properly mnged nd disposed New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

154 Chpter 17: Comptibility Biodiesel Like ethnol, biodiesel cn degrde tnk system components such s hoses, sels, nd gskets. Biodiesel itself is less stble thn regulr diesel, nd tends to brek down when exposed to ir, wter, nd metls including copper, brss, bronze, led, tin, nd zinc. Exposure to wter cn cuse microbil growth in the fuel (bio-fouling) nd mke the fuel unfit for use. In ddition, wter tht ccumultes in the bottom of the tnk cn cuse metl tnks to rust. You should confirm comptibility for your system before dding ny blends to your tnks Types of Equipment Comptibility All of the equipment in your UST system must be comptible with the type of product stored. This includes: tnks; tnk lining; piping; line lek detector; ATG sensors nd probes nd flots; STP (submersible pump) nd components; drop tube; flexible connectors; spill nd overfill prevention equipment; fill nd riser cps; dispensers; product sher vlves; hoses nd nozzles; selnts (including pipe dope nd thred selnt), Figure 17.2: Corroded STP fittings, gskets, O-rings, bushings, couplings nd boots; nd continment sumps (including tnk top sumps nd under-dispenser continment) 17.4 Steps to Confirm Comptibility You re responsible for verifying tht your system is comptible with the products you store. To confirm comptibility of your components you my need to do one or more of the following: Check tht components re independently certified, such s equipment tht is listed by Underwriters Lbortory (UL), for use with your product. You should mintin this equipment informtion onsite (e.g. in your Complince Binder) or in redily vilble loction New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

155 Chpter 17: Comptibility Confirm tht you hve mnufcturer s written certifiction of product comptibility tht specifies the rnge of product comptibility. Check the mnufcturer s instlltion instructions for your system nd components. You should mintin this informtion in your onsite documenttion (e.g. in your Complince Binder). Hve your service technicin or equipment supplier help determine the model nd mnufcturer of your fuel system components nd/or to help reserch your equipment comptibility. The instller or distributor cn help you gther the proper informtion, but you should document comptibility with informtion specificlly from the mnufcturer. See Chpter 20 for links to dditionl resources When Does Comptibility Mtter? New tnk systems should be designed for comptibility with the product to be stored. However, blends of gsoline, diesel nd other petroleum products frequently chnge. Before chnging products or introducing new blend of product to your system, verify tht the components of the system re comptible with the product. Use comptible prts nd equipment for repirs or upgrdes to your fcility. Work with qulified service technicin or engineer to mke sure your new prts or components will be comptible with the product stored Summry USTs nd components MUST be comptible with the type of product stored Underground storge tnks nd piping systems my not be comptible with ll types of products. Using incomptible equipment cn cuse equipment filure nd result in releses into the environment.

157 dsfsdf CHAPTER Trining of Clss C Opertors You should hve trined Clss C Opertor onsite ny time your UST system is operting nd n A or B Opertor is not present. Clss C Opertors re individuls who hve been trined to tke pproprite ctions in response to emergencies nd lrms cused by spills or releses from the UST system. Typiclly, these opertors re individuls who control or monitor the dispensing or sle of petroleum. They must be trined by Clss A or B Opertor BEFORE being designted s Clss C Opertor. This trining cn minimize the risks nd impcts of petroleum leks nd spills. Alterntively, the designted Clss C opertors cn be: Clss A opertors who lso meet the Clss C Opertor requirements; or Clss B Opertors (who re considered qulified to be Clss C Opertors without further trining). The trining should include pproprite responses to: product spills nd releses; tnk monitoring system lrms; fire; nd other situtions tht pose n immedite dnger to the public or to the environment. Since there re mny types of registered fcilities, there is no one size fits ll pln. Your fcility is responsible for developing site specific emergency spill response pln nd for trining your Clss C Opertors. There is little time to think when spill occurs. Your Clss C Opertor should understnd your fcility s pln nd be redy to follow it immeditely. The pln should describe immedite steps to protect humn helth nd the environment. It should lso provide contct informtion for pproprite emergency personnel, spill responders nd Clss A nd B Opertors. See Appendix A for smple contct informtion form. Trining C Opertors 6 NYCRR (d)(2) A/B It is the responsibility of the Clss A nd B Opertors to trin ll Clss C Opertors t their site. Clss C Opertors must know wht to do in cse of n emergency, lrms or spills. Figure 18.1: Most Clss C Opertors will be store clerks or the person monitoring fuel dispensing 18-1 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

158 Chpter 18: Trining C Opertors 18.1 Trining Your Clss C Opertors will be the individuls wtching over the UST system when you ren t round. Ask yourself: Will they know wht to do in the event of spill? An emergency? A lek lrm? The proper response to lrms, spills nd releses cn minimize the risk to people nd the environment. Knowing wht to do BEFORE n emergency occurs cn mke ll the difference. Clss C Opertors must be trined before they cn be ssigned opertor duties. If the trining of Clss C Opertor is meningful nd comprehensive, the opertor will be better equipped to respond nd communicte in the event of spill or emergency. Knowledge of the UST system cn help the Clss C Opertor communicte to responders wht is hppening t the site. Typiclly, Clss C Opertor trining should include the following: 1. Bsic overview of UST system components: A bsic overview of the UST system components cn help the Clss C Opertor ssist emergency response workers in the event of n emergency. Clss C Opertors should generlly know: Do NOT Post ll neglect Clss C importnt Opertor contct trining. As informtion Clss A B or t your A/B Opertor, site for esy you will ccess hve by Clss to rely CC on your Clss C Opertors. Opertors when you re not onsite. UST loction, size, nd type of product; How the tnks re monitored for leks. If you hve n utomtic monitoring system, the Clss C Opertor should know where the control pnel is. They should be ble to see nd her n lrm nd know wht to do if the lrm is ctivted; Loction of fire suppression pull sttion (if present) nd when to use it; Loction of emergency stop (if present) nd when to use it; How brekwy vlves work nd who to cll to reconnect or replce them (if present); Loction of spill response supplies nd how to use them, or who to cll for clen-up; nd Loction of sfety dt sheets.

When trining Clss C Opertors, tke the time to fmilirize them with the vrious tnk system components locted t your site. It is importnt for n opertor to know wht they re seeing Clss C Opertors should hve n understnding of your UST system to better respond during emergencies. Clss C Opertors should hve n emergency contct list posted nd ccessible. Figure 18.3: Tnk top lyout nd side view. Explin your tnk system to your Clss C Opertor. Wlk the opertor round your site nd show them the bsic tnk system components. nd wht the components do so tht they cn be better prepred to ssist inspectors or emergency responders. 2. Emergency Contct Informtion: Clss C Opertors need to know whom to contct in the event of n emergency, lek, or spill/relese. If they cnnot rech the Clss A or B Opertor, whom should they cll next? When should they cll emergency responders (911)? 18-3 New York UST Opertor Trining Progrm New York Stte Deprtment of Environmentl Conservtion October 2015

160 Chpter 18: Trining C Opertors Provide your Clss C Opertors with contct list. This list should include nmes, job titles, phone numbers nd whom to contct first, second nd so on. Mke sure your Clss C Opertors know whom to contct nd when. In n emergency, if they cnnot rech Clss A or B Opertor they need to keep mking clls until they rech responsible individul. Witing until tomorrow or just leving messge with someone is NOT n dequte response. 3. How to respond to spills or emergencies: Spills or leks cn hppen t ny time, not just while the Clss A or B Opertor is onsite. You need to feel confident your Clss C Opertor is trined to respond to emergencies correctly when you re not there to direct them. Informtion you should consider including in your C Opertor trining includes how to: recognize spills, leks, nd emergency situtions; recognize lek lrms; isolte spills nd keep people wy; stop the flow of product if possible (mny sites hve n emergency stop for this purpose); ctivte the fire suppression system if pproprite; contct the Clss A or B Opertor; know when to contct emergency responders (911); nd locte nd use the spill clen-up kit, nd/or contct the pproprite clen-up responder. Figure 18.4: Spill kit. Do you hve one of these t your site? Do your employees know where to find it? Clss C Opertors my be trined on how to use spill kit for smll spills. This cn keep the spill from getting worse. They should lso know how to stop the flow of product. Mke sure they know where the emergency shut-off switch or vlve is locted. Clss C Opertors should lso know wht to do in the event of emergencies such s : broken dispenser hose; spill during product delivery; vehicle colliding with dispenser or cnopy; or Figure 18.5: Workers put spill bsorbent on spill.
