SUMMARY This report, prepared by Roseville's Pipeline Safety Advisory Task Force, is but one part of the City's Vista 2000 (a blueprint for Roseville in the 21 st century) program. The three putposes of this repori are: ♦ A gathering of information regarding the three major pipelines, two major pipeline terminals, govemmental units, and regulatory agencies impacting safety, pipelines, and pipeline terminals in our community. ♦ lden#ification of areas of poter►tial hazard to the public, the environment and, areas for pubEic education. ♦ A presenta#ion of a series of findings and recommendations the Task Force believes will enhance the safety of our resicients and the general pubfic who work in anc! visit our community. The City has, within its bordErs, three major pipelines and two large pipeline terminals. Two pipelines #ransmit petrofeum products in and out of the pipeline terminals, which serve as storage and dispensing facilities. The third is a natural gas transmission pipeline. Wilfiams Pipe �ine Company curren#iy o�vns and operates a 12 inch pipeline, an 8 inch pipeline and 36 storage tanks in the City. Two original fi inch pipelines, now abandoned, were installed dUring 1932 and 1938. The storage tanks were erected during the period 1932 to 1952. Block (shut-off) valves are iocated at tF�e William's pipeline terminal and in the pipelines at varying d�stances from the terminal_ The closest �alve, manually operated, in the 12 inch pipeline is located in Maplewood_ The cfosest valve in the 8 incf� line is located in New Brighton and is electrically operated electrically with remote control. Amoco Pipeline Company currently owns and operates a 10 inch pipeline and an 8 inch pipeiine in the City. Amoco Oif Company owns and operates 12 storage tanks in the City. The pipelines were instafled during 1947. The storage tanks were erected during 1946 and 1971. Block valves are located at the Amaco terminal and in the pipelines at varying distances from tt�e City. The closest valves, in both the 10 inch and 8 inch pipelines are operated electrically with remote control. The closest valve in the 10 inch line is located immediately east of Roseville's eastern border. The closest vakve in the 8 inch fine is located in Minneapolis where the line crosses the Mississippi River. Northern States Power Company {NSP) owns and operates natural gas transmission and distrtbutian pipelines throughout Roseville. NSP brought natural gas to Roseville in 1954. The transmission pipeline carries natural gas at 175 pounds per square inch gage in a 20 inch pipeline from St. Paul along Rice Street to County Road B where it joins a 20 incY� pipefine from �ake Elmo. The two pipelines are pressure regulated by equipment installed in a"bungaiov�' building at the intersection of Rice Street and County Road B. A 1fi inch pipeiine then continues westerly in the southem boulevard of County Road B to Hamline Avenue. At this location, the pipeline size is �ed�ced to 10 inch. This 10 inch pipeline is located in the westem baulevard of Hamline Avenue to Roseville's northern and southern borders. Block valves and over pressure relief devices are installed and located at varying distances along this pipeline. NSP Company's gas distribution system with pressure regulators, block valves, aRd o�er pressure relief devices are instalfed throughout the City. This distribution system provides natural gas to all users in the community. Representatives from Williams Pipe Line Company, Amoco Pipeline Company and Northern States Power Company met with members of the Task Force to disc�ss and answer questions regarding facilities and operation. T�ese representatives atso completed the Fact Sheets (Chapter 4) containing much detailed informatian regarding their facilities. The Task Force also met with representatives from the State of Minnesota, Ramsey County, oiher municipaiities (fire chiefs), and industry_ These are given in Table A. Technical topics explored and described in this report include: U.S. Department of Transportation Pipeiine Safety Regulations, API Standard 653, Applicable Fire Codes, Storage Tanks, Cathodic Protection, 'Smart Pig' Tool, Hydrocarbons, Block Valves, and Firefighting Foams. Misce�laneous topics reviewed in the report inc[ude: Right-of-Way Easements, Encroachment, Line Markers, Setback Ordinance, High Voltage Electric Transmission Lines, Electric Substation, and the CAER Program. PhotogTaphs, maps and diagrams malce up an impartant part of the report to assist the reader to undersiand the various systems and their parts. There are 32 recommendations for action by the City Council and/or the City Manage�. The recommendations range from public education, inspection, encroachment, emergency notification, line markers, block valves, evacuation plans, fire drills/exercises, fire-fighting equipment and foam, incident repo�ing, CAER program, setback ordinance, a�d r!ew technology. Task Force members were asked to rank, in the order of importance, the six recommendations they considered most critical. The results are as follows: Block vafves 2_ Pipeline inspection 3. Firefighting custom built trailer 4. Optimum foam stock 5_ Encroachment fi. CAER program Note: 2 and 3 tied 4 and 5 tied CHAPTER 1 INTRQDUCTiON This report was prepared by the Roseville Pipeline Safety Advisory Task Force and presented to the Rosevifie City Council i� September, 1994. The three purposes of this report are: ♦ A gathering of information regarding the three major pipelines, two major - pipeline terminals, govemmental units, and re�ulatory agencies impacting safety, pipelines, and pipeline terminals in our cammunity. ♦ Identifcation of areas of potential hazard to the public, the environment and, areas fo� public education. ♦ A presentation of a series of findings and recommendations the Task Force believes will enhance the safety of our residents and the general public who work in and visit our community. In 1992, the City of Roseville invited residents to participate in Vista 2000 - a series of forums designed fo bring together citizens, City officiafs, and business, eciucation and civic groups to create a vision for our community's future. Participants met in July of that year to discuss problems, identify opportunities, and formuiate pfans to guide Roseville into the 21st centt�ry. Response to Vista 2000 was tremendous! More lhan 200 �esidents attended, and more than 1�0 othe�r� voiced concerns and suggestians for Roseville's future by mail. Following #he forums, over 50 residents formed six study groups to explore possibilities for Roseville's future concentrating on: ♦ Economic Develapment ♦ Environment ♦ Housing ♦ Leisure ♦ Transportation ♦ Public Safety After several monfhs of work, each group outlined its vision and set for�h goals to guide Roseville into the year 2000. 1-1 The two goals presented by the Public SafEty Group relaiing to pipelines are: ♦ lmprove the ability to respond to civi�, natural, and medica! emergencies. ♦ Strengthen fire and pipeline safety regulatior�s. This report addresses these goals. 1-2 CHAPTER 2 BACKGROUND AND HISTORY In 1932, the Great Lakes Pipeline Company (purchased by Williams Pipe Line Campany in 'l9fifi) laid its first six inch petroleum product pipeline through the area and constructed four storage tanks near the westem boundary of Ramsey County. Roseville, then a part of a much iarger area known as Rose Tov�mship, was primariiy an agricultural community. The Great Lakes Pipeline Company was a nine company consortium consisting of: Barnsdahl �il Company Cities Service Oil Company Co�tinental Oil Company Mid Continent Oil Company Phillips Petroleum Pure Oil Company Sinclair Oil Company Skelly Oi1 Company Texaco Oil Company Continentai Qif Company had a 51 % ownership. Under tf�is consortium, the following expansions occurred: Pipefines laid: 1932 1938 1950 1957 No. 1-- 6 inch (no Ionger in service) No. 2- 6 inch (no Ionger in service} No. 4- 12 inch, Newport Line No. 2- 8 inch, Duluth S�perior Line Storage Tanks erected: 1932 4 tanks 1938 15 tanks 1943 4 tanks 19�0-52 13 tanks Nos. 805, 806, 807, 8Q8 Nos. 381, 425, 509, 510, fi4fi, 649, 650, 717, 718, 719, 720, 743, 745, 904, 951 Nos. 809, 810, 8'{ 3, 814 Nos. 8� 5, 81 fi, 817, 818, 819, 820, 822, 823, 824, 825, 82fi, 827, and 828 Tank trucks loaded: confinuously from 1932 to the present time. In 194fi Amoco Oil Company (then operating as Standard Oil Company) entered the petroleum products pipefir�e and storage tanks picture in Rose Towr�ship. 2-1 Amoco's 8 inch and 1 D inch pipeffnes were laid in 1947�. Tanks were erected as fol lows: 1946 9 tanks Nos. 1, 2, 3, 4, 5, 6, 7, 8, 9 1947 1 tank No. 11 1950 1 tank No. 12 1971 1 tank No. 13 Tank trucks have been loaded continuously from 1947 #o ihe present time. Iar�k trucks are loaded 24 hours per day af both the Williams Pipe Line Company terminai and the Amoco �il Company terminal. These trucks carry petroieum products to customers throughout the metropolitan area and greater Minnesota. Williams Pipe Line Company has installed product interface apparatus beF�ind a fence on the west side of Lexington Avenue. This appara#us detects and aierts the pipeline terminal personnel of a change in product nearing the terminal. Amoco Pipeline Company has similar equipment in Littie Canada. Northern States Power Company (NSP) brought natural gas to Roseviffe in 1954, when it constructed its natural gas transmission system and its natural gas distribution system. NSP has expanded its distribution system to meet the needs o# the City's residents and commercial and industrial establishments. The transmission system consists of a pipe�ine in ihe boulevards of Rice Street, County Road B and Hamiine Avenue. A gas regula#or installation is housed in a building at Rice Street and County Road B. The distribution sytem pipelines in virtually a!i Roseville streets serve resicfential, institutionai, commercia! and industrial customers. Gas regulators (pressure regulators and pressure refief valves} are installed throughout this system. Additional information can be found in Chapters 4 and 9 regarding the petrole�m praduct pipelines and terminals and tt�e natural gas systems. According to Roseville� The Story of its Growth, nearly 1400 residents of Rose Township voted to incorporate a portion of its area into what is known as Roseville. Some records indicate (unofficially} that there were about 4fi00 residents inciuding those not eligible to vote. Rosevifle became incorporated in 'E948. 2-2 The U.S. Census gives the Roseville population as: 1950 6,437 residents 1960 23,997 residents 1970 34,439 residents 1980 35,82D residents 199� 33,485 residents Major shopping centers opened as follows: 1950 �exington Plaza 1963 Har Mar Mall 1969 Rosedale Mal! The U.S. Census data reveals that during the 1950's Roseville's populaiion increased dramatically, almost four-fold; and in the 60's two major shoppin� centers became a part of the City. The face of Roseville had changed from a farming area to an interactive community. Homes, parks, and commercial buildings appeared aiong pipeEine routes and nearby pipefine terminals. For the most part, Roseville has grown around the pipelines and terminals in our community. They are a necessary adjunct to support our lifestyle and national security. Altho«�h pi�elines and terminals pose a risk to the public and environment, they are inherently safer than transportation by tank trucks and railroad cars. Statistics indicate that the major cause of accidental product refeases #rom pipeiines is third party 'hits' during exca�ation. Pipelines and pipeline terminals are wel[ regulated by federal, state, and tocal agencies. A typicai pipeiine terminal is showm in Figure 1. Three major accidents (incidents) related to pipeEines and pipeline terminals in Roseville and neighboring communities have occurred involving fire and loss of life. Eact� is dESCrEbed briefly in the following paragraphs. !� the reader wishes mare complete information, refer to National Transportation Safety Board (NTSB) reports in the Appendix and if follow-up responses and evidence is desired, the reader can contact the NTSB and/or the Williams Pipe Line Company. The Williams Pipe Line company does not necessarily agree with the NTSB findings. In Roseville (from National Transportation Safety Board (NTSB) Report NTSB-PAR-81- 3): 2-3 At 4:45 p.m., central standard time, Aprif 1fi, 1980, gasoline at the Williams Pipe Line Company's Minneapolis terminal in Roseville, Minnesota, sprayed from the fractured cast-iron base of a station booster pump at 72 psig pressure, vaporized, and exploded after it was ignited by the arcing of an electric switch in the mainline pump control room 50 feet downwind of the booster pump. The resulting fire bumed for 2 days, fueled by gaso[ine and fuel oil leaking from ma�y burned-out flange gaskets, f�om drainage from hundreds of feet of pipe connecting 37 tanks, and from the receiving and loading manifolds. The explosion killed one person. The fire injured three persons and destroyed the receiving manifold piping and valves, pumping equipment, and four vehicles. About 3,500 barreis (147,000 gallons) of petrofeum products bumed and property damage was estimated at $3 million. The National Transportation Safety Board determined that the probable cause of the accident was fhe fracture of the base of a 30-year-old cas#-iron pump which had not been hydrostatically tested at its new instaflation. The failure ailowed gasoline under pressure to spray, vaporize, and enter an electric switchgear building 50 feet away. Ignition occurred from an efectfic arc produced by opening a switch. Contributing to #he accident was the failure of the company to (1) use expfosson-proof equipment in a potentially hazardous vapor area, and {2) fiEl the gap between the pump and its foundation with grout. ln Mounds View (from NTSB Repo�t NTSBIPAR-87J02): About 4:20 a.m., on July 8, 1986, line 2N, an 8-inch products pipeline at Mounds View, Minnesota, operated by Williams Pipe Line Company ruptured. Unleaded gasoline under a pressure of i, 434 psig spewed from a 7-1/2 foot-long opening along the longitudinal seam of the pipe. Vaporized gasoline, combined with air and liquid gasoline, flowed along neighborhood streets. About 20 minutes later, ihe gasoline vapor was ignited when an automobile entered the area. Following an expiosion-like noise, fire spread rapidly along the path of the liquid gasoline. Two persons were burned severely and later died, and one person suffered serious burns_ There was substantial property damage and soi! and water pollution. The National Transportation Safety Board determined that the probable cause of the rupture at Mounds View, Minnesota, was the faiture of Williams Pipe Line Company to correct known deficiencies in the cathodic protection appEied to the firsi 10 miles of line 2N. Contributing to the failure of the pipeline was the susceptibility of the low frequency, electric resistance welded pipe to weld seam corrosion and the Department of Transportation's ineffective inspection and enforcement program. Contributing to the extent of the damages was the failure of the pipeline company to provide adequate direction, through its procedures and training, for its employees to respond effectively 2-4 to emergencies invalving failed sections of its pipeline, ar�d the nonavailability oi remotely operated valves or automatic shutdown capabifity on the pipeline. !n St. Paul (From "Current Pipeline Safety Issues from the NTSB's Perspective", by Lawrence E. Jackson.) (NTSB Report not yet issued): On July 22, 'f 993, in St. Paul, Minnesota, a City public work's crew struck a 1.25 inch plas#ic service line inside a steef sleeve. The service iine transitioned through a coupling to a 1-inch plastic service fine. The 1-inch fine had an overstress break near an elbow, next io the building. A buiiding which included eight upstairs apartments, a food market, a computer store and a book store was desiroyed by the resulting fire and explosion, about 20 minutes after striking tY�e line. The accidenf resulted in three fatalities and 12 injuries. A team of three NTSB investigators were dispatched to the scene. No hearing or depositions have been scheduled. Areas to explore in this accident inciude crew training and compliar�ce with one-call systems and excavation regulations, and damage to pipelines by third parties. Soon after the Mounds View incident, Governor Rudy Perpich appointed a Commission oi 26 individuals of appropriate backgrounds to investigate all aspects of the safety of pipelines operating in Minnesota, as wefl as the reliability of energy supplies transporied by pipelines. Five areas of pipeEine safety were explored: ♦ Steps to improve emergency response to pipeline leaks and spills, ♦ Methods for reducing accidents caused by third-party dig-ins, ♦ Federal and state pipeline inspection programs, ♦ Government standards for existing pipelines, and ♦ Government requirements for new pipeline design, construction and routing. The Commission offered 38 recommendations based on their findings. Qf particular interest are the folEowing which have been implemented: ♦ The Minnesota Legislature should establish an office of pipeline safety in the Department of Public Safety responsible for the state inspection program, monitoring and repo�ting on the implementation of federa! pipeline standards and regulations, coordination of emergency response activities, and implementation af staie policies to reduce third-party accidents. � The Office of Pipeline Safety should be advised by a pipeline safety commission made up of technical experts and representatives from the pipeline industry, state government and the p�blic. 2-5 � Minnesota should adopt legislation which requires pipefine companies and ali other underground utility owr�ers to be members of a statewide one-cali system. !n December of 1993, the Roseville Ciiy Counci! appointed a Task Force of Rosevilfe residents to review the safety aspects of pipelines and pipeline terminals in the City and make recommendations that would minimize the risics to its residents and the general public posed by such pipelines and terminals. The Task Force began its work in January of 'f 994 and has issued this report in response to its charge. The following Table is a listing of individuals and their a�liation to whom the Task Force is indebted. Their cooperation and extra efforts played an important role in making this report possible. 2� � � �� Q � G� 4„ .O z o= F'y �C � � � �' �- Lz7 v x 0 �i.� x 4 � F" e� Q� z w � .� p � � , � � ;� Ey > Q > F" 'fl � Q � � Fr Q � GL� Lr� U x �� O •° F a�i `� � � c � � ,� � 00 � � z� c �, °' � � �. �, U C7 � Q N � ^ u" � cV � � � � � C � = d � �� ti� � � M � M U � � ed .� w � M � � �tl � [� � U � i � G � -, �3 ' • �3 � � � y � � � � � � a� a, p • E '� r�~ o c•~°� �" x:^ o � � W � E-�+ a, o [j � � '� (j � o'�j -� z = c� � � � �'� >, °� . -� �, �c V o U. o �� QF..�� d o ° Q � O w r0 'v p 0�" � C E-- E- Q 0. � F-� � O Gi R, U Q Li LL C7 � C.'� L� � � � � � � � L � � 0 � � � � � �� .c� � ,C � � t�j � 4 . c� �'� �' � °- �i �� 3.0 ��' � � �.� Q� � 0 ti � � c, � t�o �: y �: � �: � �: p., ,.: a� o � F� � r� �� a, � a n i� � .� � � .ai U C H 0 V O O U 0 Q �. � U � Q F �, w �, a� � a� VO U .� � � � rn F � � � 0 c a � •� O � p- � � U � U �, O ,� � 3 � � E–� w 0 V � � .� a.

One system is their transmission system, the other their distribution system. The transmission system consists of 20 inch, 16 inct�, 10 inch and a small amount of 6 inch pipe. This pipe is installed �n the boulevards of Rice Street, County Road "B" ana aiang Hamline Avenue as shown in Figure 9. During the summer of 1994, NSP refocated and insialled new 10 inch pipe between County Road 'B-2' and County Road 'C' as part of Ramsey County's road reconstruction prog�am in that area_ The system operates at a pressure of 175 pounds per square inch gage {psig). The steel pipe is coated and cathodically protected. {Additional technical information about this pipeline system is contained in the Fact Sheets of Chapter 4). To maintain an adequate supply of natural gas during high demand periods, a 20 inch pipelir�e from NSP's Lake Efmo system joins the Rice Street pipeline at Rice Street and County Road B as shown in Figure 17. The pipelines, valves and pressure regulators at this location are enclosed in a residential bungalow type house so as to blend in with neighboring properties. The equipment is electrically operated by remote control from NSP's St. Paul Dispatch Center. , Automatic pressure regulators, located throughout #he City, control and reduce the press�re #o the distribution system. Pressure regulators are also equipped with pressure relief vaives. Line markers, Figure 5, appear ir�termittently on utility poles and on formed steel posts. The naturai gas distribution system, Figure 10, consists of steel and plastic pipe ranging in size from 1/2 inch to 8 inch_ The pipe is installed in ihe boulevards of vi�tua�iy every Roseville street. The system operates at pressures ranging from nnro psig to 60 psig, and provides natural gas to afl NSP customers in the community. Original pipe in this system is steef; plastic pipe is used in new installations and where repiacement is needed. Pressure reguEators maintain a uniform pressure a# user locations as well as to reduce system pressure. Pressure relief valves are an integral part of this system. (For additionai information about the distribution system refer to the Fact Sheets of Chapter 4). 3-1 NSP's Gas Emergency Plan esfiatrlishes procedures and defines responsibilities in the region as required by NSP Operating and Maintenance Standards including Emergency Procedures. The primary objective of the plan is to assure: ♦ Immediate recognition and reporting of emergencies. ♦ Prompt and appropriate response in order to: protect the public, employees and company facilities, prevent or minimize property dama�e, and re-establish gas supply shouid interruption occur. Emergency Procedures include: Fire or Explosion Near or Directly Invvfving Gas Systems Gas in Building Outside Leak Emergencies Emergency Rapid Shutdown Procedures Emergency a# District Regulators Emergencies at a Town Border Station (TBS) Natural Disasters Civil Disorders Emergency 8 Temporary AbovEground Service to Customers Failed Material & Gas-related Incideni Investigation NSP also maintains a Damage Prevention Program to infiorm: excavators, gas customers, and the general pubfic of the existance of natu�al gas pipeline system and what to do to prevent damage to NSP facilities during excavatian activities. Amoco Oil CompanylAmoco Pipeline Company (Amoco) Amoco is a producer of petroleum products at two refineries, one at Mandan, N.D. and the other at the Whiting Refinery in Whiting, Indiana_ Amaco afso moves their petroleum product in their own pipefi�es and distributes their products from a storage terminal in Roseville by tank truck or other company's pipelines. Ninety to 95% of the petroleum products came into the Roseviile terminal from Mandan, the remainder from the Williams Pipe Line Company terminal, on the other side of County Road C in Roseville. Facilities at the Amoco Oil Company Terminaf (See Figure 1fi) ir� Roseville are: 3-2 A. Storage ianks ♦ There are 12 active tanks used to store light petroleum prod�cts, petroleum distillate and aircraft f�ei. 4ther small tanks are used for pipeline breakout {pop-off} and gasoiine additives. The large tar�ks were constructed in �946 and are considered to have an indefinite iife when maintained correctly. The tanks range in size from 966,000 galions to 3,570,�00 gallons. In normal operation, all ihe tanks average about 6Q% of capacity. ♦ Amoco has never had a tank farm fre. The only incident was a water well pump fiire in a smali metal building. They have had some ground water contamination from tank spills. Ground wafer is cuRently being monitored by 40 ground water wefls. Clean up is continuous. ♦ Alf of the 12 large tanks were cleaned, inspected and tested in the last six years. A daie has not been sef for future testing. ♦ in 1992 and i 993 all the piping within the termina! area was replaced and installed above ground so ihat leaks and spills are observed easiiy. � None of the 12 farge #anks are protected by a built-in fire suppression system. All tanks are surrounded by dikes which were surveyed in 1988 and found tQ meet requir�d codes. ♦ There are about 1fi0 to 200 valves in the system, and each valve is checked monthly to assure it can be operated easily. ♦ The tank and manifold areas are checked visually each day. ♦ The termina! has a water system for fire control. Hydrants are strategically located. This water system is below grade and is tied in#o tf�e Rosevil[e fre water system. ♦ Tank bottoms have been protec#ed cathodically since the 1960's or 1970's. Cathodic protection was upgraded in 9 990 and is monitored regularly by a co�sultant. ♦ T�e small additive tanks were built in 1992. B_ Load�ng Areas for Trucks ♦ Most of the product stored at this terminal is shipped out in tank trucks. In 1993, Amoco Oil Company built a new tank truck loading facility and 3-3 discontinued using the oid one. The new rack is of the "bottom loading type" and is an open buifding with an overhead roof. It is equipped with an automatic foam system trigge�ed by overhead heat and uttravioiet sensors. Vapor from the tank loading is captured in a carbon absorption unit. C. Pipel�nes, Figures 1'I, 13, and 14 ♦ A 10 inch pipefine is bi-directional, pumping to the Rosevi�le terminal or #oward Dubuque. When product in this line is flowing toward Dubuque, the pressure is normaliy 650 psi. at the discharge side of the p�mp in RoseviliE_ When the line pumps product to Roseville, pressure is 10 to 40 psi. This line is not in continuous use. At the terminal in Roseville, there is a motor operated valve controlled either from the terminal or from Tulsa, 4klahoma. This line, #raversing easterly ihraugh the center of Roseville, exits Rosev+iis at Rice Street about a block south of Roseville's northern border. A block east of Rice Street into Little Canada, t�ere is a manual and an electrically (motor} opera#ed �alve, Figure 8, which can be controlled from Tulsa or the terminal. This Eine was built in 1947. ♦ An eight inch pipeline, northerly from the terminal, exits at Roseville's northwest corner. This line ends at the Amoco refinery in Mandan, N.D. Produci flows in this line from Mandan io Roseville and is in constant use_ The average pressure in this Iine at Roseville is � 50 psi. This [ine was buift in 1947. There is a manuai and motor operated valve at the terminal. The nearest �alve beyond Roseville is electrically operated and is located in Minneapolis near where it crosses the Mississippi River, as shown in Figure 13. This line and the 10" line were'Smart Pig'* tested in Roseville in 1987 ar�d '1990 respectively. They have not been hydrostatically tested. ♦ Two pipelines operate soiely between the Amoco Terminal and the Williams Pipe Line Company (Wilfiams) terminal. These fines and others in the area of tt�e terminais are shown in Figure '!4. The eight inch fi�e between the two terminals is used to transmit gasoiine and fue! oil bidirectonalfy between the two terminals. The other pipeline is an eight inch pipe above grade at the Amoco Terminak and a six inch pipe below County Road "C" a�d belaw grade at the Wilfiams Terminal. This iine is used to transmit ethanal from the Williams terminal to the Amoco terminal. 3-4 ♦ All pipe[ines are protected cathodically* about every 10 miies through Roseville. Amoco spends fi million dollars a year maintaining their right-of-way in the fve state area. Amoco experiences encroachment by the property owners. Safety Programs ♦ A breakout (pop-off} tank is available to handle excess pipeline pressure or to accept excess product if needed. ♦ The tota! termina[ area is inspected visually each day, and tanks are checked every morning. Amoco personnel are on duty at the terminal 22- 24 hours a day, seven days a week. After normal working hours, gates are closed and can be openad onEy for tank trucks whose drivers have been issued special access computer cards. ♦ The terminal has an internal alarm system for emergericies. ♦ The terminal has several 30 pound, hand carried, Purpte K(a powder fire fighter) fire extinguisheTS on hand and a 150 pound and a 350 pound wheeled units. All employees are trained in their use. There is an annual fire training program in pface for alf employees trained to manage major emergencies. Foam is also available at the terminal. SOQ gallons of foam is available for �se by the Roseville Fire Department. ♦ Pipelines are patrolled by airplane at ieast every two weeks. ♦ The Roseville termina! is subjected io an annuaf Cotporate safety inspection_ ♦ Spill management table top drills are conducted frequently. Williams Pipe Line Company The Williams Pipe Line Company (Williams) contracts with petroleum producers to move product via pipelines to the variaus markets in the central part of the United States. When a petroEeum product reaches the Williams terminal, it is stored and eventuaily dispensed into wholesaie distributors' tank trucks for local use. Williams does not own any product it distributes. "' As explained in Chapter 5, Technical Topics. 3-5 The te�minal in Roseville on County Road C is a dis�ribution poini for the Twin Cities area for many petroleum products. The Roseville terminal afso acts as a distribution point for other parts of Minnesota and adjoining states throughout its pipeline system. Facilities at the Terminal A. Storage tanks ♦ There are 37 tanks ranging in size from 84,000 gallons to 3.33 miiiion gallons_ ♦ The maximum capacity of aEl 37 tanks is 79,800,000 gaElons, b�t rareiy is there more than 40,000,000 gallons in storage. ♦ These tanks contain ethanol, gasoline, jet fuel, fueE oil, and water. ♦ Pipelines carrying petroleum from tanks to distribution and pumping centers within the terminal are above ground so that leaks and spilis are easily observed_ Each tank has a manual and an electrically (motor) operated block (shut-off) valve. Also, since the fire in 1980, Williams Pipe Line Company has installed additional valves in the tanlc lines to minimize product �low in case of fre. � �h� ta�k a�r�a has �oser��0i� wate� li�es �r� thre� si�es a� rd at leasi 4hree hydrants on each side. ln addition, Williams Pipe Line Company has an internal water system with hydrants strategically �laced throughout the tanks an� di�tributior area. The system is norrnal�y dry� ta prevent freezing, but water will flow when a hydrant control valve is opened and the air in the fine expelled. ♦ No tank has an installed fire suppression system such as CO2 nou�es or dry chemical nozzles_ Each tank is diked to control any liquid flow. Tanks that contain volatile fuel have vapor control systems. ♦ At ieast part of the tanks presently in use were built in the 1930's and 1940's. These tanks have been improved by welding the otiginal rivets and seams. 13 tanks were built in the 1950's_ There is also a regular inspection and maintenance system in place to repair the inside bottoms when needed. The outside of the tanks are icept painted and cathodic protection is applied to the outside bottom. Tank life is considered #o be indefinite by Williams Pipe Line Company officiafs. 3-6 ♦ In a maintenance shop at one side of the terminal, Williams carries approximately 35, five-gallon buckets of foam producing material. Inductors can be placed in these buckets to produce foam for fire s�ppression. ♦ ln addition to foam chemicals, Williams has several sizes ofi Purple K fire extinguishers. There are 30 Ib. hand held extinguishers and 35� Ib. wheeled extinguishers at the terminal. These are suitabie for small spot fires. B, Loading Areas for Trucks ♦ Ai! oi the product stored at the Williams terminal is either sent elsewhere by pipelines or is distributed locally to the surrounding area by tank trucks. The tank truck bottom foading process is a 24 hour 7 days a week operation. The loading area is new and is designed for safety. The building is roofed but otherwise is open. A Purple K fire extinguisher system is piped at floor level and overhead. It is triggered by overhead infrared sensors. In addition, as trucks are filled, the vapors are removed and combusted. C. Pipelines, Figures 11, 13, and '14 There are five active pipelines leaving the terminal area, pius fin+o six inch pipelines that have been purged of product and decommissioned, i.e. no longer in service. The active pipelines are as foilows: ♦ A 12-inch line (No. 4), buitt in the �950's traverses ihe center of Rosevifle in an easterly direction to Newport, Minnesota. This line exits Rose�ille about 2 blocks south of County Road C and Rice Street. The nearest shut off vafves are at the terminal on one end, and Highways 36 and 6� in the Menard's parking lot. This vakve is operated manually. The high pressure cut oi# is 1000 pounds per square inch {psi) operating pressure is 950 psi. ♦ An eight inch pipeline (No. 2}, traverses northerly from the terminal, alongside the railroad track and exits Roseville at County Road D_ The nearest valves on ihis line are at the termina! and in New Brighton at the 2 mile post_ The New Brighton valve is eEec#rically {motor) operated and is located behind the New Brighton maintenance st�op_ This line to Duluth- Superior was built in 1957; ii has a higt� pressure cut off of 925 psi and - can be operated up to 875 psi. 3-7 Both of these pipelines can be operated b+directionally and are used for the complete range of petroleum products. ♦ An eight inch pipeline, Figure 14, to the Amoco Oil Company terminal is �sed to move product back and forth between the two terminals. This pipeline is owned by Amoco Oil Company. ♦ Wi!liams has another eight inch pipeline, Figure 14, that con�ects with Amoco Oil Company's main eight inch pipeline on the east side of the railroad tracks. This gives WiE[iams another pipeline to receive product from Amoco. ♦ Williams receives ethanol in railroad tank cars or tank trucks onfy, not through pipelines. Amoco Oii Company does not have an ethanol unloading facility. A six inch Iine from Williams to Amoco provides Amoco Oil Company with ethanol. Safety Programs ♦ In � 993, the Williams Pipe Line Company's 12 inch No. 4 pipeline was hydrostaticaffy tested; this line passed its test. The eight inch No. 2 pipel�ne was hydrostatically tested in '� 99'f . This fine passed its test. ♦ WilEiams Pipe Line Company employs an environmental and health speciaiist whose job it is to supervise the training of employees in a five sta#e area. This specia[ist is also responsible for overseeing fire and emergency training and OSHA compfiance. Annual emergency drills are planned for the future. ♦ The Williams Pipe Lir�e Company Fire Contro� System at their terminal is shown in Figure 15. Public Education ♦ Williams P.ipe Line Company has a number of public education video tapes available for showing on Roseviile's N Channel. The tapes of interest to Roseville are: Quiet Steef Safety: The Right Decision Right of Way Maintenance/Tree Clearing 3-8 Right-of-Way EasementslAgreements Amoco Pipeline Company and Williams Pipe Line Company have right-of-way easements/agreements for their pipelines in Roseville. These easements, which vary in width, were negotiated many years ago when the pipelines were first layed_ Pipefine aperators are requried by DOT regulations to inspect their pipefine routes an a regular basis. A clear right-of-way is necessary to facilitate this inspectian. Amoco and Williams each budget rnonies annually to keep their right-of way clear for inspection and maintenance purposes. Amoco and Williams have right-of-way agreements throughout Roseville with: residents, railroads, commerciai establishments, and the City. Northern States Power Company also has right-of-way easements/agreements with: Roseville residents, railroads, commercial estabiishments and the City for NSP's natura! gas transmission and distribution pipelines as well as for its high voltage electric transmission lines as shown in Figures 9, 10, and 12. 3-9 CHAPTER 4 FACT SHEETS Representatives from Northern States Power Company (NSP}, Amoco Oil Company/Amoco Pipeline Company (Amoco) and Williams Pipe Line Company {Wiliiams) were asked to furnish certain per�inent informafion regarding their facilities.

V. • wpproximau CHAPTER 5 TECHNICAL TOPICS In order to fully comprehend and judge the quality of the pipelines and pipeline terminals in Roseville, a number of technical reports and informatior� were sought and submitted to the Task Force. The following is a summary of that information. (Note: regutations cited apply to new construction_ Prior consiruction complying with regulations in effeci at the time, was "grandfathered" in.) U.S. Department of Transportation (DOT) Pipeline Safety Regulaiions The Minnesota �ffce of Pipeline Safety (MnOPS) inspects intrastate and interstate pipeline in accordance with U.S. DOT Pipeline Safety Regulations 191, 192 and 19�. These regulations cover both natural gas and hazardous liquids transported through pipeiines. Hazardous liquids are defined as: petroleum, petraleum products or an�ydrous ammonia. The materials, design, constr�ction and installation specificatio�s are s�t forth, incl�ding the depth at which the pipelines are to be buried. The regulations mandate that pipeiines will have a cathodic protection system. A complete record showing all materials, sizes, and locations of all component of the pipeEine system must be retained for the life of the system_ The frequency of testing and inspections is set forth. The types of tests and observation methods are listed. Records of all required tests wiil be made and retained for the fife of the pipeline. Annual reports will be filed for all transmission, gathering and distribution systems. A program to observe surface conditions on and adjacent to the transmission line righ#-of-way for leaks, construction activity and other factors affecting safety and operation must be in place and operational. For natural gas pipelines, the location of customer meters, service regulators, valves, and service lines as well as the connections for main piping is specified, depending on the type and location of installation. For hazardous materiafs, valves must be installed on the suction end and the discharge end of a pump station; on each line entering or leading a breakout storage tank area; on each mainline at locations along the pipefine system that will minimize damage or pollution; on each laterai takeoff from a trunk line; on each side of a water crossing that is more than 100 ft. wide from high-water mark to high-wafer mark; and on each side of a reservoir holding water for human consumption. Line markers, Flgure 5, for transmission [ines of natural gas must be placed at each crossing of a public road and raiiroad and wherever necessary to identify the Eine to reduce the possibility of damage. In high density population areas tt�is may be 5-1 excepted where impractical ar where a damage preverrtion program is in effect. Minnesota's Gopher One Call system provides such a program. Line markers, Figure 3, for buried hazardous materials pipelines must be located at each pub�ic road crossing; at each railroad crossing; and in s�cient number along the remainder of each buried line so that its locaiion is accurately known. ln heavily developed urban areas, line markers are not required where the placement of markers is impractical and the locat govemrnent maintains current records. Notification must be made by teiephone at the earliest possible time following an accident or safety related incident. This is followed by reports to the Natio��al Transportation Safety Board which will conduct an investigation if warranted. The DOT Pipeline Safety Regulations state that a complete emergency plan wiil be in place and operational with the cooperation of fire, poEice and any other pertinent public officials. TF�e Minnesota Offce of Pipeline Safety has the right of inspection and e�forcement for the intrastate operators. MNOPS has been ce�tified as an interstate agent for the Federal Office of Pipeline Safety (FOPS} to conduct interstate inspections and refer the res�lts to the Regional 4ffice of FOPS in Kansas City, MO for enforcement of non- compliance findings. Tank lnspection, Repair, Aiteraiion and Reconstruction. API Standard 653. This American Petroleum Institute Standard is an industry standard and as such does nat carry any governmental oversight. The first edition was issued in January 1991 with a supplement added in January, 1992. APi Standard 653 contains eleven sections, ten ot which cover technical subjects such as: Suitability for Service, Brittle Fracture Considerations, Inspection, Tank Repair and Alteration, Welciing, Examination, Testing and Marking as well as Record Keeping. Of interest to the Task Force is Sec#ion 4, lnspection. This Section has ten parts including: lnspection Frequency Considerations, External lnspection, lnternaE inspection, Checiclists, Records, Reports and Inspector Qualifications. Part 4_2 lnspection Frequency Considerations list eleven factors to be considered when determining inspection intervals for sto�age tanks. The list includes but is not limited to: The nature of the product stored. The results of visuaf maintenance checks. 5-2 • Corrosion allowances and corrosion rates. • Conditions at previous inspecf:ons. • The methods and materials of construction and repair. • The location of tanks. • The potential risk of air or water pollution. • Leak detection systems. • Change in operating mode. • Jurisdictional requirements. Jurisdictional regulations, in some cases, conirol the frequency and interval of the inspections. These regulations may include vapor foss requirements, seal condition, feakage, proper diking, and repair procedures. Knowledge of such regulations is necessary to insure compliance with schedufing and inspection requirements. External inspections are delineated in two subparts: Routine In-Service Inspections and Schedufed Inspections. Routine tnspections may be performed by owner/operator personnel and shall noi exeeed one month. Scheduled Inspections are to be performed by a quali�ied inspector at least every five years, or at the quarter corrosion rate of the shell. Internal (tank} inspections are required primarily to: Ensure that the bottom is not severeiy corroded and leaking. Gather the data necessary, for the minimum bottom and shell thickness assessments detaifed in Section 2_ As applicable, this data shall also take into ac�ount external ultrasonic ihickness measurements made during in-service inspections. Identify and evaEuate any tank bottom settfement. lntervals for internal tank inspections are to be determined by the corrosion rates measured during previous inspections or based on experience with similar in service tanks. In no case shall the intemal inspection interval exceed 20 years. Alternative Inspection Intervals are also permitted. Inspection checklists are detailed in the Appendix. The standard requires that the owner/operator maintain a complete record file for three types of records covering constructian, inspection history, and repair/alteration history. Records may not exist for older tanks_ Applicabfe Fire Codes Prior to 1989, the National Fire Protection Association Code 30 for Flammab{e and Combustible Liquids was in efiect for the design, construction and installation of 5-3 siorage tanks for such liquids. Requirements for other facilities such �s industrial plants, processing plants, refneries, chemical plants and distslieries are also detailed. Chapter 6 specifies requirements for Bulk Plants and Terminals. Requirements �or storage, b�ildings, loading and unloading facilities, wharves, electrical equipment, sources of ignition, drainage and waste disposal, as well as fire control are included in this chapter. h+lany of the storage tanks at the pipeline terminals in Roseville were instalied to comply with Code 30. fn 1988, the Uniform Fire Code was issued by fhe Intemational Fire Code institute and became effective in Minnesota by superseding Code 30 in 1989. This code prescribes regulations consistent with nationally recognized good practice for the safeguarding to a reasonable degree of life and property from the hazards of fire and explosion arising from the storage, handling and use of hazardous substances, materiafs and devices, and from conditions hazardous to life or property in #he use or occupancy of buildirtgs or premises. The Uniform Fire Code is comprehensive and tect�nologically current_ It covers a wide range of faciEities; for example: incinerators, vacant buildings, airports� bowling alleys, garages, lumber yards, dipping operations, automobile undercoating, welding and cutting, as well as bulk plants or terminals. Article 79, Division XIV, Bulk Plants or TerminaEs details the requirements for such facilities. Some of the subjects covered are: • buildings • ventilation • storage • loading and unloading facilities • electrical wiring and equipment • sources of ignition • drainage control • fire protection Construction beginning in 1991 at the pipeline terminals in Roseville must comply with the Uniform Fire Code. 5-4 There are no "after installation on going" inspections specified in Code 30 or the Uniform Fire Code. Above GroUnd Storage Tanks Come in a Variety of Designs (from Fire Protection Handbook, 19fi9 Edition) ♦ Atmospheric - tanks for pressures of 0 to .5 per square inch. ♦ Low pressure tanks - pressures .5 to 15 pounds per square inch. ♦ Pressure tanks - pressure above 15 pounds per square inch. Pressure type tanks and pressure vessels are used normalfy for vapor conservatio� for liquids having high vapor pressures. Four Different Types of Tanks 1. Ordinary cone roof #ank. 2. Floating roof tank - roof moves up and down with level changes. 3. Lifter roof tank -#iquid sea�ed roof moves up and down with voEume of vapor. 4. Vapor roof tank - has a flexible diaphragm at the tank's roof and moves with vapor volume changes. The probability of a fire in an approved tank is much less than a fire in an ordinary building_ Where tanks are adjacent #o a building, the fire in the building exposes the tanks more often than the tanks expose t�e buildings. A major factor in fires involving storage tanks has been either the fatlure of the piping or ti�e valves controlling the tanks (corrosion problems). Floating roof tanks provide maximum fire safety for above ground use; thus they are permitted to be located closer to a property line than other types of tanks. Expfosions can occur when the floa#ing roof tanks are near empty and a flammable vapor is created. Cathodic Protection Cathodic protection, as mandated by federaf regulation, is a method of mitigating external pipeline corrosion which is defined as the eroding of a metal pipe by electrochemical action. When naturalty occurring electricity enters the metal (cathode), metaf will be consumed where a current ieaves the metal (anode). This reaction can be inhibited by electricaify energizing the pipe (cathode) and placing high silicon casi iran or pieces of graphite in remote ground beds (anodes) in electricaf contact with the pipe. Thus, the iron or graphite will be corroded, no# the pipe. Another method is to electricaiiy connect the pipe with a metal higher in the electro-motive force series. The 5-5 more acti�e metal is then consumed by eorrosion. To minimize electrical power requirements, steel pipelines are coaied w�th an electrical insufating material. Very smalf holes, called "hofidays", in the coating are possibie and can become anodes thus corroding the pipe at such locations. Cathodic protectior� inhibits the holiday areas fram corroding. 'SMART PIG' Deformation/Slope Tool The deformatioNslope tool, known in the industry as a'Smart-Pig', is a completeiy self contained electronic survey instrument. The fool is capable of 360 degree survey coverage of #he inside of a pipe. As the instrument moves through the length of a pipeline, it finds, locates and records the following pipe conditions: cfents buckles wrinkles ovality mechanical damage wall thickness changes diameter changes flat spots over pressure expansion metaE foss caused by extemal or iniernal corrosion The instrument can also locate pipeline appurtenances such as flanges, valves, couplings, etc. Detection is done electronically. Results are reported as high resolution graphics on a computer screen and/or printout. History of Hydcocarbons Related to Leaks fn the case of a pipeline or tank rupture or feak, if the line contains: ♦ Natural gas, which is predominantly methane, it wiii rise into #he air and can displace air creating a lethal atmosphere, free of oxygen. It can ignite and send flames high in the air. It can enter a confined area and explode if ignited. ♦ A liquid fuel, the liquid wilk flow to the lowest area contaminating soii and water. If the liquid is volatile, then both liquid and vapors wikl flow to the kowest area, but vapors can be affected by air cuRents. Vapors can ignite in a flash fire or can cause a fire over all the liquid_ Vapors can flow into a confined area (building, house, car) and then explode if ignited. Block Valves Biock {shu# ofFj valves are used to stop the flow of product in a section of pipeiine, into 5f or out of a storage tank and in the manifold area of a pipeline terminal. These valves can be �f the �ar�ually operated ty�e or of the electric power operated type as shawn in Figure 8. Manually operated valves req�ire the presence of an individual to open and close fhe valve. Electric power operated vatves are motor driven and can be eq�ipped with a remote contro! feature. Power operated block valves can also be manually operated at the valve. Biock valves at the pipeline terminals in Roseville are shown schematically in Figure 14. Block valves in the Amoco Pipefine Company and Williams Pipe Line Company pipelines in and around the twin city area are shown in Figure 13. Block valves in Northem States Power Company's #ransmission and distribution systems are shown in Figures 9 and 10. Fire Prevent�on and Firefighting Foams Syratheti� foam� �re r�cr�gnized in the Unifc�rm Fire G�de as eff�ctive materials for preventing and extinguishing petroEeum product fires. They are available for frefighting purposes in two types: an Aqueous Film Forming Foam (AFFF) and an Aqueous Film Forming foam/Alcohol Type Concentrate (AFFF/ATC}. AFFF is a syntt�etic �irefighting foam concentrate designed for use on no�-palar, hydrocarbon hazards. When proportioned with water and applied with conventional foam or wateNfog equipment, AFFF provides excellent control and extinguishment of Class B fires by spreading a vapor-seaiing film over the fiquid fuel. This vapor seal inhibits reflash e�en when the foam blanket is ruptured and also allows the product to be used to secure non-ignited spills. AFFF provides excellent penetrating and wetting qualities when used on Class A fires. This is important when extinguishing deep- seated fires in wood, paper, rubber tires, and other ordinary combustibles. AFFF is available in 1°�, 3%, and 6% concentration. AFFF can be used with conventional foam equipment with fresh, sea, or brackish wate�. Self-educting foam noZZles and foam nozzles with in-line eductors are among the most common types of hardware for application. This foam can be applied to fi�es simultaneously with dry chemica! firefighting agents because the two are compatible. This foam material may be stored in its unopened shipping container without cF�ange in its originai physical or chemical characteristics. AFFF/ATC is a versatile firefighting foam for protection of a wide range of Class B f�ammable liquid hazards. AFFF/ATC is an all synthetic flm formi�g foam designed for protection of water sol�ble polar solvents as well as wa#er insoluble hydrocarbon 5-7 fiammable liquids. When used with fresh, sea, or brackish water and foam generating equipment, AFFFIATC is transformed into a vapor-blanketing foam with exceflent extinguishing and securing abilities. The eifectEVeness of AFFF/ATC on a wide range of flammable liquids and ordinary combustibles can eliminate the need to stock a variety of frre�ghting agenis. AFFFlATC is available in 3K3 or 3Xfi concentrations. AFFF/ATC is recommended fior use in a wide variety of firefighting foam application devices. Examples are foam chambers, forcing foam makers, and aspirating foam nozzles. In addition, practical applications have been demonstrated in a number of discharge devices such as non-aspirating sprir�kler�, r�ater sp�ay nozzl��, an� �n•aterffog nozzles. AFFF/ATC is effectiv� in subsur#ace injection systems for gasoline, crude oil, and most water insoiuble hydrocarbons. The subsurface injection system utilizing AFFF/ATC foam is the safest, most reliable system ior the fixed protection of storage tanks of water insoluble hydrocarbons. AFFF/ATC is UL listed on both hydrocarbon and polar salvent liquids through standard sprinkler heads. 1n addition, AFFFIATC is also listed for use with handfine nozzles and foaen chambers for top side t�nk protectior�. When stored in accordance with the manufacture�'s recommendations, AFFF/ATC foam has good stabiliiy. Annual inspection of systems as prescribed in NFPA 1 � is recommended. It should noi be mixed with other agents. � CHAPTER fi GOVERNMENTAL UNITS AND REGULAT4RY AGENClES The following govemmental units and regulatory agencies identified bekow have oversight responsibility or associated involvement in pipeline safety issues ar�d related activities. A summary of the roles a�d responsibilities of each organization is as folfows: FED�R�� QV��Rl�4lI�� A�iD �J�RTOO�f�OL ORGAI�i�TICfV�: 1. U.S. Department of Transportation (US DOTj This agency is responsible for issuing pipefine safety rules and regutations for interstaie and intrastate pipelines carrying natural gas, liquified natural gas, and hazardous liquids. A.) Federal Oifice of Pipeline Safe#y (FOPS) This agency oversees interstate pipeline operations, compiiance witF� ruies and regulations, and enforcement. This includes administration of the Natural Gas Pipeline Safety Act of 19fi8, the Hazardous Liquid Pipeline Safety Act of 'E 979, and the Hazardous Materials Transportation Act of 1974. Proposed changes to pipeline rules and regulations issued by the Department of Transportation are broughi by pipeline owners, the public, or agency personnel. OPS is a part of the Research and Special Programs Division of U.S. DOT_ B.) National Transportation Safety Board (NTSBj As an independent Board reporting directly to Congress, NTSB investigates and reports on incidents involving interstate pipeiines to affix cause, responsibility and recommend actions to prevent or reduce future incidents. This agency has issued reports regarding the Roseville pipeiine terminal explosion at the Wilfiams Pipe Line Company facility in 1980 and the WiEfiams Pipe Line Company rupture and fire in Mounds View in '1986. 2. U.S. Department of Labor, Occupationa! Safety and Health Administration {US OSHAj This agency oversees, administe�s, issues and enforces rules and reguiations relating to on-the job employee safety, including empioyee safety at pipeline company facilities. Authority for adminis#ration of applicable rules is delegated to the Minnesota Department of Labor, Office oi Occupational Safety and Health _. 6-1 to the [�llinr�esota Departmerrt of Labor, Office of Occupatianal Safety and Health {MN OSHA). 3. Fire Protection Associa#ions A.} Intemationa! Fire Code Institute. This organ+zation is composed of tf�e International Conference of Building Officials and the Westem Fire Chieis Association. The Institute correEates the provisions of the Uniform Fire Code and the Uniform Building Cade_ The Uniform Fire Code prescribes regulations consistent with nationally recognized good practice for the safeguarding to a reasonalbe degree of life and property from the hazards of fre and explosion arising from the storage, handfing and use of hazardous substances, materials and devices, and from condifions hazardous to life or property in the use or occupancy of buildings or premises. I� 1989, Minnesota adopted the Uniform Fire Code. B.) National Fire Protection Association (NFPA). This organization is composed of fire service, business and industry, health care, educationa! and other institu#ions and individuals in the fields of insurance, government, architecture and engineering. This Association develops and publishes standards irttended to minimize the possibility and effects of frre and explosion. Prior to 1989, the NFPA Code 30 was in effect ir� Minnesota. Code 30 was used for the design, construction and installation of storage ta�ks for flammable and combustible liquids. STATE AGENCfES: 4. Minnesota Department of Public Safety (MnDPS) This State agency has direct authority over {among others) the 4�ce of Pipeline Safety, State Fire Marshal's Office, and Division of Emergency Management, and is authorized to issue rules and regulations relating to the operation ot these divisions. A.j Minnesota Offce of Pipeline Safety (MnOPS) The Minnesota Office of Pipeline Safety (MnOPS) reguEates intersiate and intrastate pipe�ine operators thraughout Minnesota. k� existence since September, 1987, the office consists of an authorized s#aff of 15, which s-2 includes ten inspectors. MnOPS is affiliated with the State.Fire Marshal's Office, which is a division of the Minnesota Department of Public Safety. The State Fire Marshal is the Director of MnOPS. The 56 pipeline operators regulated by MnOPS transmit hazardous liquids, �atural gas, propane, and �iquified natural gas. Following the tragic Mounds Vi�w accident of 198fi, the Legislature created the MnOPS through the 1987 Pipeline Safety Act (Minnesota Statutes 299J and 299F}. Because ofi its excellent program fior inspecting pipeline operators within the state, the Federal Office of Pipeline Safety - (FOPS) granted MnOPS interstate agent status in 'f 991. This status gave MnOPS the responsibility of inspecting all pipelir�e operators within Minnesota's borders. Minnesota is one of only five states nation wide w�th this level of inspection authority. MnQPS has jurisdiction over nearly 4,000 miles of hazardous liquids pipelines and over 4fi,000 miies of natural gas and propane pipelines, as well as three fiquified natural gas facilities. AI! pipeiine operators in Minnesota receive at least one inspection annually. MnOPS also conducts inspections on a finra, #hree, or four year cycle as required by MnOPS and/or FOPS policy. An inspe�ion is defined as: the examination of all or part of an opeTator's pipeline faciiities tha# are under the control of an administrative unit that provides sufficient communication and supervisory controls to ensure uniform design, construction, inspection, operaiion, maintenance, and emergency response procedures far the facilities. Among other concerns, the geographicaE size of a facility is also taken into consideration. Although the inspection program for hazardous liquids and natural gas pipeline facilities are not identical, the foliowing major components are common to both: operation and maintenance plan, emergency plan, damage prevention program, training and public education programs, safety related conditions, accident reporting, emergency release reporting, failure investigation, line markers, corrosion control, and abandoned faciliiies. The field inspection portion includes any item(s) of concern identified during the inspection, or other subject areas judged appropriate by the inspector. In addition to the annual inspection program, MnQPS conducts: random "spo#" inspections, 6-3 2. �ollow up inspections to previous inspections, 3. design and construction inspections, 4. training of operators, 5. accident and incident on-site inspections and investigations, 6. Gopher State One-Call violaiion investigations, and 7. compiaint investigations. ln the event of a pipeline incident or accident, MnOPS investigates to determine probable vioiations of state and federal laws, and works to prevent reoccurrence of similar incidents. MnQPS has the authority to issue civil penalties for violaiion of Minnesota pipeline laws. !i aEso acts as the enforcement authority for the Gopher State �ne-Call program_ The Federal Office o# Pipeline Safety enforces Federal Pipeline Safety Regulations and administers the federal drug and alcohol testing program. MnOPS assists local governments in developing emergency response plans anci conducts an aggressive public education program through public speaicing opport�nities, the state iair exhibit and participation on committees such as the Metropolitan Utility Coordinating Committee and the Central Utilities Coordinating Committee. B.} Division of Emergency Management This Division within the Minnesota Department af Public Safety, coordinates and oversees the effectiveness of emergency planning, response and mitigation of natural, technological, radiological, and civil emergencies including pipeline incidents. It encourages and assists witt� emergency planning and coordinates a state response if requested. It also proposes changes in regulaiions from suggesfions brought by pipeline owners, the public, or agency personnel. The D�vision has ar� emergency operations center located ir� the Sta#e Capi#ol where incider�ts are repo�#ed and passed on to other State agencies such as MnOPS, MPCA, and the Fire Marsha!'s office. C.) State Fire Marshal's Office The Minnesota State Fire Marst�al's Office oversees National Fire Protection Association and Minnesata Fire Prevention rules and regulations as they apply to a variety of �ire prevention issues, incfuding pipeline terminals in Minnesota. The State of Minnesota adopts the Uniform Fire Code and enforces the standards set forth. fi� The State Fire Marshal's Office reviews plans tor flammable and combustible liquids and gas installations subject to Fire Marshal ruies. 5.) Minnesota Pollution Control Agency {MPCA) This State agency proposes, issues, and enforces rules and regulations regarding spills, lealcs and clean up of pipeline incidents, both interstate and intrastate, and incidents involving spilis, leaks, and clean up at pipeline storage facilities. It also enforces U.S. Environmentai Protection Agency rules and regulations under interagency cooperation agreements as permitted by law for state and federal agencies. MPCA dces issue permits for pipeline facilities, but specific permit rules have not yet been adopted. The Tanks and Spiils Section regufates the use of petroleum and certain chemical storage tanks as well as addresses the results of tank #aifure. This section includes the spills response and above ground permit programs. 8.) Gopher State One-Call (GSOCj Gopher State One-Cal! provides a damage pre�ention service in Minnesota. State Statute 21fi D requires anyone planning to excavate using power driven equipment to notify GSQC at ieast 48 hours (excluding weekends, holidays, or emergencies) in advance of starting to dig. Even when hand digging, a person is encouraged to calf GSOC if he/she is unfamiliar with the location of buried utiiities. GSOC takes detaiied information from callers who are planr�ing excavation work, proces�es it �n a�omputer, and notifes undergrour�d �4i�ifiy operatars that may have facilities in the described work area. These underground utifity operators dispatch locators to matk (with the appropriate colors) the locatior� of their underground utifities. By law, underground utiity operators have 48 hours to mark their underground utilities_ Underground utility operators do not have the responsibility to mark any private utilities. Therefore, care should be exercised anytime digging takes place. The person who is doing the work is responsible for calling GS�C. [f the homeowner does his or her own excavation work, the homeowner is responsible for caEiing GSOC. If #he homeowner hires a contractor to do the work, the conkractor is responsible for calling. There is no cost to the excavator for th�s locate service. After the underground utilities have been marked, and the 48 hour time frame fi-5 has elapsed, the excavation worlc may commence. Emergency locate service can be provided when necessary. The Minnesota Office of Pipeline Safety enforces the laws regarding Gopher State One-Call violations. COUNTY ORGANIZATIONS: 7.) Ramsey County :te u� �I; A.) Sheriff s Department All Roseville 911 ca!!s go directly to a dispatc� center locateci in the � Ramsey County Sheriff's Patrol Station at County Road E and Victoria in Shoreview. Following published and practiced procedures, the dispatcher determines the nature of the prablem. At that time, Roseville Poiice are notified and, if necessary, the Rose�ille Fire Department_ The dispatch center, upon verification of a break in a pipeEine (natural gas or hazardous liquid) would notify the proper owner/opera#or of the pipeiine. O1 �t�� The dispatch center has all of the phone numbers and confacts necessary for notification in the event of a pipeiine incident. Depending upon the size of the incident, a1l notifications will be made to implement Roseville's Emergency Plan shoufd an emergency be decEared. The Sheriff s Department has participated in al! of the practice drills held by Rose�iffe during its emergency plan training. The phane number and contact lists are constantEq updated, and a copy of the Roseville Emergency Plan is on �" f!e and at hand at #he SherifF Department's dispatch center. �si B.) Ramsey County Department of Emergency Services {RCES) u The Ramsey County Emergency Services is a division of the Ramsey h` County Sheriff's office. RCES provides assistance to communities after an initial disaster is under control in whatever support or fnancia! �U assistance is available including interaction with state and federal agencies. !t has an emergency operations center wEth a separate communications system and a nEtwork of volunteers. RCES also coordinates county-wide emergency preparedness and procedures. �� C.) Ramsey Couniy Division of Environmental Health (RCDEHj �� .+ The Ramsey County Division of Environmenta! Health is a division of the Ramsey County Depa�tment of Public Health. Within RCDEH, there are two Sections: Community Sanitation and Hazardous Waste. The Community Sanitation Section provides regulatory and inspection .. services to food, beverage, and lodging establishments, swimming pools, and mobile home parks within the narth suburban area of ihe county. This Section alsa provides ir�ve�figaiive services for public �iea�th nuisances in the same service area. The Hazardous Waste Section provides regulatory and inspection services to generators af hazardous waste and the facilities which manage hazardous waste throughout the County. Both sections issue licenses #o their affected populations and enforce local and sta#e rules within the scope of their programs. LOCAL AGENCIES: �. j C6ty af R�se�rille A.) Roseville Fire Department {Figure 't9} The Roseviiie Volunteer Fire Department consists of 78 members responding from three stations with a totai of nine vehicles. The stations are focated at 2701 Lexington (Station '� ), 2501 Fairview (Station 2), and 2335 Dale (Station 3). The department responds io all fire calls and requests for extrication in motor vehicle accidents. Station 1 houses one engine and a heavy rescue #rucic. The other stations each house two engines and a 100 foot aerial ladder. There is also a 4x4 grassfire truck at station 3_ The three stations are staffed from fipm uniil 6am six days a week and all day Sunday_ Two members are on duty at ai� timas except at Station 1 which has one person standing by. Drills are held the first three Wednesday and Saturday mornings and #he #irst three Thursday evenings of each month. Members must attend at least six drills per quarter and respond to 33 percent of the calis per year. There were approximateiy fi00 calls in � 993. The annual training schedule includes the areas of hazardous materials, natural gas, and flammable fiquids. NSP, Amoco, and Williams all contribute time and personnel to the depa�tment in these areas. Bo#h engines at Station 2 are equipped with foam. One has 300 gaifons in its tank and 1200 gallons of water, altowing 10,000 gallons of foam to be produced. The other truck carries 35 gallons of foam concentrate. A!i of ihe department engines have foam inductors. The Roseville department is also the foam reserves storeho�se for the Capitol City Mutual Aid Association, of which Roseville is a member. lf more foam is needed in an emergency, 3M Company has provisions to supply large . 6-7 amounts, neighboring departments have small quantities, and Williams Pipe Line Company has a small quantity on hand. Foaming agents allow a blanket of small bubbles to cover a fire's fuei (especially flammable liquids) and separate it from air, thus smothering the fire. B.) Roseville Fire Chief The Fire Chief plans, develops, and supervises a department of trained volunteer firefghters so as to provide rapid and effective response to all emergencies and rescue incidents. This person also reviews and evaluates new concepts and/or approaches to the City's fire protection services. C.) �iosevilie Fir� M�r°��ia� This individual plans and schedules #he _City's fire inspection program, administers fire safety permits, enforces applicable fire codes through analysis of building plans, inspects bui#dings and resolves code violations, conducts pubiic safety activities and provides commercial and industrial occupants with training regarding fre preven#ion. The Fire Marshal also reviews plans for sprinkler, alarm, and life safety systems, water supplies, access to buildings and conducts and witnesses tests of same. D.j Roseville Fire Inspector Conducts fire inspection of new and existing structures within the City, enforces and implements applicabie codes for the removal of hazards and/or violations. The Fire Inspector aiso coordinates and conducts fire safety training within the City. E.) Rosevilie Emergency Qperations and Center (EOC} The City of Roseville has a formal emergency aperations plan witi� a mission to establish and maintain an emergency operational capability to save lives, provide for continuity of government, a�d to mobilize resources to recover from an emergency. The plan was created to be prepared for a variety of possible natural and technological hazards including tornados, blizzards, severe thunders#orms, high winds, chemical spills, aircraft accidents, radiological accidents, extensive fires, and pipeline breaks. The Civil Defense Director is the City Manager and the Civil Defense Coordinator is tF�e assistant Police Chief. Other participants in an emergency situation wo�fd include the Po4ice and Fire departments, other department heads and city staff, the Mayor and City Councii, Police reserves, pipeline company representatives, County Sheriff's o�ce, mutual aid responders .: from other cities, State Patrol, Red Cross, utility companies, Poliution Control Agency, Minnesota Office of Pipeiine Safety, and hazardous clean up contractors. Roseviife Emergency Operations Centers include the primary EOC at the training room at City Hall and the secondary EOC at Fire Statio� 3. Incident command centers are established typically at or near an emergency site. .• CHAPTER 7 MISCELLANEOUS T4PICS Right-of-Way Easements For a pipefine company to construct and maintain a pipeline through a piece of property, the company has to either own the property or secure a right-of-way easement from the property owner. Such easements allow pipeiine company personnel ar�d equipment access to the property for the purposes of laying/reiaying pipe, inspection, clearing, repairing, and maintaining the pipeline. Qver the years, such easements have changed from a description of a greater section of land to a smaller parcel of prope�ty. A typicaf right-of-way easement is as follows: RIGHT QF WAY AGREEMENT For and in consideration of the sum of $ , paid by Pipe Line Company of , the receipt of which is hereby acknowledge does hereby grant to Pipe Line Company, its successors or assigns, the right to lay maintain, operate, re-lay and remove at any time a pipe line or pipe lines #or the transportation of oil or oil products, gas and water, and if necessary, to erect, maintain, operate and remove telegraph and telephone lines, witF� right of ingress and eg�ess to and from the same, on, over and through certain lands situate in the County of and State of and described as follows: Section , Township , Range Property owners wishing to know about pipeline easements on their property should read the abstract for their property. Encroachment Webster defines encroachmeni as the gradual intrusion or infringement upon the proper�y or rights of another. An example of encroachment is shown in Figure 6. U.S. Department of Transportation (DOT) Pipelir�e Safety Regulations req�ire pipeline operators to have and implement a program to observe surface conditions on and adjacent to the pipeline right-of-way for leaks, construction activity, and other factors affecting pipeline safety and operation. Line Markers DOT Pipeline Safety Regulations 192 and 195 require line markers to be placed and 7-'E maintained for both natural gas transmission pipelines and for hazardous liquids pipelines afong the route of the line. Typical line markers in Roseville are shown in Figures 4 and 5. Although the reguiations delineate specifc crossing locations siach as public roads, railraads, ar�d bodies of water for line markers, certain exceptions exist. For exampie, in heavily developed areas, and in the case of natural gas pipelines where a damage prevention program {Gopher State One-Call) is in p#ace, exceptions are permitted. Line markers are required to carry a warning, caution, or danger notice as we![ as the operator's name and a telephone number where the operator can be reached at all times. Setback From a Pipeline D�T Pipeline Safety regulations state that no new hazardous liquid pipeiine may be located within 50 feet of any private dwelling, industrial building, or place of public assembly unless the pipeline is provided with at least 12 inches of cover in addition to that specified in Subpart D of the regulations. The State of Minnesota has published Model Setback Rules effective July 1991. The rules state that buifdings and places of pubEic assembly subject to the Rules shall not be cons#ructed c[oser to a pipeline than the boundary of the pipeline easement. The Rukes are �pplir.able to new construction and unless a community de�elops its awn setback ordinance, the State rules apply. The City of Maplewoad's Pipeline Setback Ordinance states that ali newly crea#ed buildings and newly crea#ed building lats shall accommodate a setback of at least 100 feet from a pipeiine. Buildings, pipelines, and variances are delineated in the ordinance. High Voitage Electric Transmission Lines As shown in Figure 12, Northem States Power Company has constructed two high voltage electric transmission lines through Roseville. One of these ii�es operates at 115,OQQ volts, the other at 345,000 vofts. A comparison of F�gures 11 and 12 will show that in some areas of Rasev�lle one or both of the electric transmission lines are in the same corridor as the Amoco Pipeline Company and/or Williams Pipe �ine Company's pipelines_ tn these areas, tt�e electric transmission iines are virtually above or in close proximity to the pipelines as shown in Figures 2 and 7. 7-2 Northem States Power Company's (NSP) Rose Place Electric Substation Northern States Power Company owns and operates an electrica! substation just west of Roseville's Fire Station on Fairview Avenue. This substation is connected to NSP's 1 f 5,000 voli transmission line and provides e�ectric power to Rosedale, the Crossroads, and the Rosedafe Commons shopping malls. Two large power transformers, two bus tie circuit breakers with remote control and automatic reclosir�g features plus remote controlled line-bus and tap switches are arranged as shown in Figure 18. This arrangement provides a high reliability scenario for maintaining electric power to the shopping malls from a dedicated substation. Supenrisory Controf and Data Acquisition {SCADA) equipment at NSP's DeEivery Operations Control Center permit NSP system operators to control and observe switch and circuit breaker staius at the substation. Community Awareness Emergency Response {CAER) Program The CAER program is a concept deveioped in 1985 by the Chemical Manufacturers Association (CMA) in response to the tragedy in Bhopal, India. For CMA, this incident demanstrated the need to increase the level of awareness and preparedness for. emergencies in communities. CAER is a program to promote cooperation between the public and private sectors in matiers of emergency planning and response. The goa{ is for industry and goverr�ment to jointly devefop an agreed-upon community plan for improved protection of lives, property and the environment in the event of release of hazardous materials or natural disassters. Minnesota has embraced tF�e concept of CAER with the development of various grou}�s over the past few years. The first official Minnesota CAER group was Wakota CAER, formed in 1985, covering the southern Washington and northern Dakota counties area. Wakota CAER has over 35 member representatives, including industry, IocaE, county and state government, Red Cross, U.S. Coast Guard, educators, public safety officials and others responsible for safety, health and environmentaf protection. Since that time, other groups have been formed in the Fridley area, St. Cloud area, Steele County, and Duluth. Each CAER group must develop its own program unique to the geographic area it covers and the types of hazardous materials it may encounter, but there are some general guiding principles common to all CAER groups, including: 7-3 ♦ Coordinating and sharing resources -- at least experience and knowledge; sometimes people, equipment, and other emergency response tools. ♦ Deveioping a group plan and individual plans to deal with disasters in a consistent and comprehensive way. ♦ Providing safety education to the pubf�c. ♦ Providing training for industry and pubfic agencies. t Conducting emergency drills to test the emergency plan. Additional information about the CAER concept can be obtained from the Minnesota Pollution Control Agency. 7� CHAPTER 8 FINDINGS AND RECQMMENDATIONS The distrib�tion of petroleum products and natura! gas is a fact and necessity of modem life. The Task Force recognizes that these products by their very nature have the poteniial of creating a serious threat to pubiic safety. Recognizing #he hisforical development of the system and that Roseville, with its 1940- 1960 growth pattern, simply grew around and over the current system during a period of time when many of the reguiations and safety guidelines were far iess stringent or simply did not exist; there is no question that if this distribution system was being built today, ii would be built differently. However, programs and regulations for inspecting, testing and maintaining pipelines and pipeline terminals are now in place to ensure that these facilities continue to operate reliably for years to come. It was the charge of the Tas�c Force to review the system from a historica! perspective, to ascertain who is involved in managing the system, who regukates it, what the regulations are, who inspects the system and what contingency plans exist in the event of an incident that could be a threat to public safety and the enviror�ment. A general cor�clusion of the Task Force is that: significant effort is being made to properly manage the system; that the safe operation of the system is a major concem of those in charge; that current operators are subject to considerable regulation by the federal and s#ate govemments; that, on the whole, extensive contingency plans exist and that all units involved in impfementing such plans are in communication with each other and are reviewi�g and updating the plans on an ongoing basis. With that said, t�e Task Force oi�ers the following Findir�gs and Recommendations. We believe the City should use the Findings and Recommendations to develop strategies and effecf change to rectify and improve the deficiencies and areas in need of attention that were identified as a resul# of our work. Finding{s) ♦ Williams Pipe Line Company has provided the City with 3 educational video tapes; �iet. Steei, Safety - The Riaht Decision, and Tree Clearing_ Recommendation 1.� The City of RosevilEe sho�ld show the three video tapes regularly on the City's N channel. The City should also encourage Williams Pipe Line Company to make the three tapes available to the County Library in Roseville. 8-1 Finding(s} ♦ There are several U.S. GovernmenURed Cross publications availabfe (free} from the Ramsey County Emergency Services Division and the local iibrary regarding emergency preparedness for residents. Recommendation 1.2 The City should, through its loca! N channel and newsketter, make alf residents aware of these publications; and should, by special mailir�g, advise residents in the area of the pipelines of the publications. The City should aiso make copies of the publications available at Ciiy Hall. Finding{s) ♦ The City does not have an official list of prope�ties with pipeline right-of-way easements or properties abutting such easements. Recommendation 1.3 For the purpose of providing pertinent public information to occupants of properties with pipefine easements or abutting properties with such easements, the City shouid develop and maintain a list of street addresses within the City having or abutting pipeline easements. Finding(s} ♦ The majority of pipeline accidents/incidents are caused by contractors and residents excavating with power tools in the area of an underground pipeEine. Minnesota has a utiiity locate program En place, it is known as Gopher State One-Cal! (GSOC). ♦ Virtually a11 contractors are aware of the GSOC program and use i#s services. Roseville residents and thE general pubiic, however, are not aware of the program. ♦ Minnesota's Gopher State One-Call {GSOC} Program has pubfications available to contractors and homeowners regarding excavation regulations and kocate serv�ces. Recommendations 1.4 The City shoufd make GSOC publications available at Ci#y Hall and 8-2 pubtish a"Call Before You Dig" article in our newsletter annually in the April and/or June issue. 1.5 The City should persuade GSOC to produce a short (10 minute) video #ape regarding excavation regufations and locate services. The video tape should then be made available to cities that can and will show it on the City's N ciiannel. Finding(s) i Roseville is now a highly populated residential community with active shopping malis and pubiic gathering places sucF� as office buildings, schools and parlcs with pipelines nearby. Natural gas and hazardous fiquids pipeiines and pipeline terminals abound in our City. Recommendat�on 1.fi Because of Rosevifle's high exposure to natural gas and hazardous liquid pipelines, the City should persuade the Minnesota Office of Pipeline Safety to conduct inspections of alf pipelines in Roseville on an alternate year basis. Inter-terminal and 'no longer in service' pipelines need to be included in this program_ Finding(s} ♦ There is no procedure in place whereby the Minnesota Office of Pipeline Safety is made aware of construction projects in the vicinity of pipelines under their j�risdiction. Recommendation 1.7 The City shouEd advise and request inspections by the Minnesota Office of Pipeline Safety when street projects or major building projects are undertaken in the area of Amoco's and William's hazardaus liquid pipelines, and NSP's gas transmission pipelines. Finding(s) ♦ Over the years, as Rosetown changed from a farming area to Roseville, an incorporated City, encroachment has occurred in the form of stored automobiies and eq.uipment, trees and out buildings. Tornados and wind storms can uproot trees resulting in damage to nearby pipelines. DQT pipeline regulations require that pipefine routes be kept clear and inspected regularly. Pipeline companies ._ 8-3 have in their right-of way easements the right to access private property with workers and machines ior the purposes of inspection, maintenance, and repair. Recommendation 1.8 The City of Raseville should persuade the Minnesota Office of Pipeline Safety to walk and observe pip�line routes annually in Roseville and advise the pipeline campanies what action they need to take to clear the right-of-way for inspection purposes so as to be in compliance with Fede�al reguiations. The City should participate in this effort as the City of Eagan did in '! 993. Finding(s) ♦ API Standard 653 specifes a pragram fior Tank lnspection, Repair, Alteraiion and Reconstruction. This is an industry standard and as such is impiemented by the owner/operaior. Section 4 of the Standard details inspection requirements for storage tanks. Pipefine terminals are subject to inspection by Roseville's Fire Marshal. The Fire Marshal uses his training and the Uniform Fire Code to verify conditions at the terminals. Recommendation 1.9 The City should direct the Fire Marshal and the Fire Inspector to make more frequent inspections of the pipeline terminals. Every 6 months, one time by the Fire Marshaf the next time by the Fire Inspector is recommended. The current inspection procedure should continue with the addition of a verification #hat Amoco Oil Company and Wilfiams Pipe Line Company are conducting storage tank inspections and maintaining records in accordance with lnspection Section 4 of API Standard 653. When inspections and records indicate #hat repair and/or maintenance of a tank is requirecf, the Roseville Fire Marshal shaEf verify that such repair/maintenance has been undertaken. Finding(sj ♦ Amoco Pipeline Co., Williams Pipe Line Company, and Northern States Power Company have, on their iine markers, an emergency telephone number to call in the e�ent of a leak or spifl. The Amoco and Williams pipeiines, in many parts of the City, are very close to one another. To determine which number to call is uncertain. 8-4 Recommendation 1.10 The City sho�ld persuade the pipefine companies to add a"Cail 9� 1 fn the Event of Emergency" sign at each line marker location and other above grade equipment installations. 911 is the offcia! emergency call number in Minnesota. Finding(s) ♦ Nort�em States Power Company's pipeline line markers are installed infrequently and inconsistent!y atong the route of its natural gas transmission iines in the City. The route is in the boulevards of Rice Street, County Road B and Hamfine Avenue. Many of the line markers are old, in poor condition and are attached to utiiity poles. � Pipeline Safety Regulations require line markers at speci�c locations for natural gas mains and transmission �ines. However, certain exemptions are permitted where there is a damage preveniion program in effect. Minnesota's Gopher State One-Call Program is a damage prevention program. Recommendations 'i _ 11 The City of Roseville should persuade Northern States Power Company to install additional line markers alang the gas transmission line route. Line markers should be of the post mounted type and placed at regular intervals along the route. Proper#y line locations should be given consideration. 1_ � 2 The Task Force recommends line markers be installed where operating pressures are 60 pounds per square inch or more. Finding(s) ♦ Block valves are located in the three major pipelines at irregular intervals. Some of the valves are manualfy operated, others are electrically operated_ Manually operated block valves require tha# an individual be dispatched to the valve location in order to operate it. Electrically operated block valves can be aperated firom a remote location. ♦ Roseville's iow elevation allows petroleum products to back-flow from outlying areas when pump pressure is removed and block vafves are open_ 8-5 ♦ In the Amoco pipeline system, there is an electrically operated block valve near the City's eastern border and one near where the pipeline crosses the Mississippi River in Minneapolis. ♦ In the Williams pipeline system, there is an electrically operated block vaive nearby in New Brighton, two miles from the terminal in Roseville. in the Wiiliams pipeline to Newport and beyond, the closest valve to Rosevil}e is near tt�e intersection of Highways 61 and 36. This valve is manually operated. ♦ Northern States Power Company`s natural gas transmission pipeline in Roseville has se�era( biock valves in the pipeline along Rice Street and several along Hamfine Avenue. There are no block valves in the pipeline along County Road B between Rice Street and Hamiine Avenue. All block valves in the NSP pipeline system are manually operated. Recommendations 1_'13 The City should persuade Amoco Pipeline Company to install an electricaliy operated, remately controlled block valve in their 8 inch pipeline near the northwesi corner of Roseville. 1.14 The City should persuade Williams Pipe Line Campany to ins#all an electrically operated, remotefy conkrolled block valve in thei�- 12 inch pipeline near Roseville's eastern border, i.e. Rice Street. i.15 The City should persuade Amoco Pipefine company and Williams Pipe Line Company to install electrically operated, remotely controlled block valves in their pipelines at a location near Bennett Lake in Roseville's Central Park. 1.1 fi The City s�ould persuade Northern States Power Company to install two strategicafiy located, manually operated block valves in their 16 inch pipeline in the boulevard of County Road B, between Rice Street ar�d Hamline Avenue, {a distance of appraximately 2-�12 miles). Finding(s) ♦ Pipeline spi�ls and leaks along the route of a pipeline can have serious negative impacts on human life and on the environment. :. Recommendation 1.'�7 The Fire Marsha! should ensure that evacuation plans are in place for all commercial, public and high density residential buildings in Roseville (could apply to ali emergencies). Finding(s) ♦ In addition to regular firefighter training, the City currently participates in emergency response training which includes one major drill each year. These drilis include a variety of hypothetical situations including plane crashes, tomados, chemical spills, and major fires. Participants inciude poiice, fire, o#her local officials, and mutual aid cities. Drills have included pipeEine emergencies in the past, but there is no set frequency for this training. Recommenda#ions 1.18 Training on pipelinE emergencies and petroleum tank fires should be conducted at least once every five years. This training should include cooperative representaiion from all affected pa�ties inciuding but not fimited to local emergency personnel, City staff, County and State officials, mutual aid participants and local pipeline companies. 1.19 The City needs to conduct pipeEine fire exercises at the foliowing locations: ♦ residences westerly (one or two blocks} from Central Park at Lexington Avenue. ♦ rear of Crossroads Shopping Mall ♦ northerly from County Road C at the railroad tracks east of Wifliams Pipe Line termina! to Long Lake Road ♦ southwest corner of Rice Street and County Road B where NSP has a farge installation of pipes and regulator equipment enciosed in a typical wood frame building. Finding(s) ♦ Neither pipeline terminal has a� automatic fire suppression for their petro4eum storage tanks. ♦ If a spill, tank rupture ar overtlow occurs, the best solution is to prevent the fire with foam. Next best is to put the fire out with faam and the last resort is to let it burn and prevent other tanks from catching fire. 8-7 Recommendations 1.20 The City oi Roseviile, Amoc� Qil Company and Williams Pipe Line Company should coordinate their plans for carrying foam on hand so as to determine t�e aptimum amount of foam eacf� should have on hand to combat a terminal, pipeline or tanker truck spill�re. 1_21 Roseville Fire Department should have more foam solution on hand an� use outdated stock for drill purposes. Finding{s) ♦ A variety of custom built trailers are availabie to enhance the fre fighting capabilities of a fire department. TF�ese trailers are equipped to transport and apply foam salutions to pipelines, pipefine terminaEs and tanker truck spills/fires. ♦ Foami�g agents are the approved method for fighting petroleum fires. Recommendations 1.22 Tt�e City of Roseville should procure and be the sole owner of a custom built trailer to combat petroleum spills/fires. Roseville's Fire Department personnel should determine what apparatus and capabifities the trailer should have to best serve the needs of the department and the City. or The City of Roseville should pursue a mutual aid agreement with neighboring communities for the procurement and co-ownership of a custom built trailer to combat petroleum spills/fires. or The City of Roseviile should persuade Amoco Oil Company and Williams Pipe Line Company to join the City in procuring and owning a custom built trailer to combat petroleum spills/fires. Finding(sj ♦ There is a concern that a naturai gas or petrofeum product pipeline fire in the vicinity of either one of Northern States Power Company's high voltage electric transmission lines could endanger the lives of fire fighters and the public by :: collapse ofi the electric conductors and/or their supporting strucfures. In addition to the time it would take far a Northem States Power Company (NSP) representative ta arri�e at the scene, NSP has advised that it could take an additional 15 to 45 minutes, after arriving at the incident, #o deenergize a high voltage #ransmission line. Recommendation 1.23 The City should explote with Northem States Power Company the means � by which NSP could more expeditiously deenergize its high voltage transmission lines in the event of a pipeline fire. For example, an "early alert" to NSP co�id be put in place when the first incident commander arrives a# the scene even though a fire may not have yet been ignited. Finding(s) � The Mir�nesota O�ce of Pipeline Safety, as an agent of the Federal 4ffice af Pipeline Safety, performs annual and special inspections of inter and intra sta#e natural gas and hazardous liquid pipefine operaiions throughoui the State (including Roseville). These inspections are made to verify that pipeiine operators comply with federa� regulations. Reports are filed with the Regional Federal Office of Pipeline Safety. ♦ Minnesota's Fire Marshal's 4ffice pertorms inspections of new construction at pipeiine terminals to verify that the design and construction comply with the Uniform Fire Code. Reports are issued after each inspection including a final "exit interview" letter. ♦ Natural gas and hazardous liquid pipeline operators are required to file incident, accident, annual and safety related reports in accordance with Federal Pipefine Safety Regulations. Recommendations 1.24 The City should request that a copy of the reports as stated in t�e abave Findings be sUpplied routinely to the City Manager for action. Finding(s) ♦ Wf�en calied, the Roseville Fire Department responds to incidents at the Ro�evifle pipeline terminais, the pipelines and ta�ker truck spills/fires. :- Recommendation '! .25 The City Council should require that the Fire Chief furnish the City with a copy of the Minnesota Fire Incident Reporting System (MFIRS) form as filed with the State Fire Marshal's office for each pipeline, pipeline terminal and tanker truck incident in the City_ The City Manager should then take appropriate action. Finding(s) ♦ A Community Awareness Response {CAER} program can be impiemented that promotes cooperation between the public and private sectors in maiters of emergency planning and response. The goal is for industry and government to jointly develop an agreed-upon community plan for �mproved protection of lives property and the environment in the event of release of hazardous materials or natural disasters. ♦ CAER groups t�ave been formed in the Fridley area, Si. Cloud area, Steele County, Duluth, and Washington - Da�COta counties. ♦ The Ramsey County Public Health Department through its En�ironmental Health Division issues licenses to hazardous waste generators and hazardous waste management facilities. TF�e City of Roseville has, within its borders, numerous com�anies that use, generate, manage and wa�ehouse hazardous materials. Recommendation 1.26 The City of Rosevifl� in consultation with the City's Fire Marshal and Ramsey County's Environmenta! Health Division, should identify companies who generate, use, manage and warehouse hazardous materiaks within the City`s borders. The City should then encourage identified companies to form a Roseville CAER program similar to the CAER program in Fridley MN and other Minnesota CAER groups. Finding(s} � Minnesota's setback rule for new residential or other development allows buildings and pkaces of public assembly to be constructed up to the boundary of the pipeline easement. 8-10 ♦ Unless a community has its own setback ordinance, the State's setback rule applies. The City of Maplewood has developed a setback ordinance more restrictive than the States setback rule. Recommendations 1.27 The City of Roseville should adopt a pipeline setback ordinance using tt�e Ciiy of Maplewood's ardinance as a guide. 1.28 The City of Roseville should not allow encroachment of structures by private or public entities over a pipeline easement. Finding{s) ♦ A major cause of pipeline accidents are "third party hits" by excavators digging with power equipment ir� our streets and boulevards. ♦ Although some of the 'hits' are unreported nicks (an ultimate source of leaks) others break through the pipe resulting in a reiease of oil, gasoline or natural gas. Recommendation 1.29 Excavating contractors, when operating in Roseville, shou[d be required by ordinance to have a cellular telephone or mobile raciio at the job site. This communication equipment is to be used by the contractor to call 911 immediately to report a pipeline product release or call the pipeline company in the event of a'hit' without a product reEease. Finding(s) ♦ The Minnesota State Fire Marshaf's office reviews plans and specifications for �ew construction for flammable and combustible liquids and gas installations subject to the Uniform Fire Code. Recommendation 1.30 The City of Roseville should formally request the State Fire Marsha! to review existing equipment and procedures at #he Amoco Qil Company and Williams Pipe Line Company ierminals. Upon completion of the review, the Fire Marshal, in conjunction with the City's Fire Marshal, should advise the City of any additional/n�w technology, equipment or procedures that would further reduce the risk of fire at the pipeline 8-11 terminals. The City should review and pursue the Fire Marshal's advice with the pipeline operator/owner for action. Finding(sy ♦ Current Minnesota Occupational Safety and Health Administration (MnOSHA) inspections are conducted in reaction to empioyee complaints. Recommendation 1.31 The City of Roseville should persuade MnOSHA to inspect conditions at the Amoco Oil Campany and Williams Pipe Line Company on a five year schedule. Northern States Power Company's operations in Roseville should also be on the same schedule_ Finding(s) ♦ From Snelling Avenue to Fairview Avenue, two large pipelines (Amoco and Williams} carrying petroleum products at high pressure are installed in a right-of- way (R-O-W) earthen embankment. At this location, the R-O-W is near and along the rear of a shopping mall's parking ramp complex to i#s south and at the rear of several blocks of homes to its north. The shopping malls are Rosedale Commons and Crossroads. ♦ There is an alley, with foading docks, between the R-O-W and the shapping mall's parking ramp complex. The alfey contains numerous storm water catch basins and se�eral fire hydrants. One of Roseville's fire stations is located nearby on Ckeveland Avenue. ♦ The embankment and terrain slope downward from Fairview Avenue towards Snelling Avenue. A pipeline leaklspill in this area would cause iiquid fuel to flow from the R-Q-W into the alley and storm drains and/or backyards of the homes. This combina#ion of pipelines, shopping malls, parking ramp, residences, land and embankment elevations produces a potential for a serious incident of fire and pollution. Recommendation 1.32 The City should requi�e its Public Works and Fire Departments to consult with Amaco Pipeline Company and Wifliams Pipe Line Company to determine how to minimize the risk of fire and poll�tion in this area. 8-12 For example, #he risk could be minimized by the installation of strategicaiiy located electrically operated-remotely controlled block valves, encasing the pipe in concrete, cons#ructing a liquid retaining wall, annua! pipeline inspections, the use of tarpaulins and sand to block the flow of petroleum into the infirastructure and the availability and procurement of inflatable (bull-bags) bags that can be inserted into the storm sewer catch basins. 8-13 CHAPTER9 PHOTOGRAPHS, MAPS AND I�IAGRQMS This chapter contains the various fgures referred to in the report_ Figure 1 Petroleum Pipeline Terminal Figure 2 Line Markers for Petroleum Pipelines with H.V.
