Monterey St Gasoline Release
lf�"COR International Incorporated April 4, 2001 Mr. Doug Nelms Mr. Greg Stratton City of San Luis Obispo Public Works Granite Construction Company (805) 783-7712 fax (805) 773-0103 fax Subject: Results of Soil Sampling and Analysis, Monterey Street Sewer Project San Luis Obispo Dear Mr. Nelms and Mr. Stratton: SECOR International Incorporated (SECOR) has reviewed the analytical results of soil samples collected as part of the above referenced project. Excavated soils suspected of containing petroleum hydrocarbons have been segregated and stockpiled at the City Corporation Yard on P,rado Road. On March 30, 2001, SECOR collected samples from two soil stockpiles. The stockpile of suspect soil was designated as Stockpile A and the pile considered uncontaminated was designated as Stockpile B. Two samples were collected from each stockpile. The samples collected from the suspect pile (Stockpile A) were intended to represent worst -case samples. On April 2, 2001, SECOR collected one sample of suspect soil that was excavated from Santa Rosa Station 1 +84 along the utility alignment. This sample was collected as a composite of the stockpiled soil. The analytical results of the three soil samples collected from suspect soils did not contain detectable concentrations of BTEX compounds. The two samples collected from Stockpile A on March 30, 2001 did not contain detectable total petroleum hydrocarbons (TPH). The sample collected on April 2, 2001 contained 11 milligrams per kilogram (also parts per million) TPH, which is well below the 100 part per million action limit observed by the City of San Luis Obispo Fire Department (SLOFD). The two samples collected from the stockpile considered to be uncontaminated did not contain detectable TPH or BTEX. The concentrations of total lead measured to date in the soil samples are within the range of naturally occurring levels and are well below the SLOFD action limit of 50 parts per million. Copies of laboratory reports and chain of custody forms are attached. Based on the analytical results obtained to date from the soil stockpiles at the Corporation Yard, the excavated soil is acceptably uncontaminated and is not subject to regulation or restrictions by the SLOFD. The soil should be suitable for use as clean fill, subject to the engineering properties of the soil. 3437 Empresa Drive, Suite A, San Luis Obispo, CA 93401 805.546.0455 805-546.0583 Fax www.secor.coni Mr. Doug Nelms and Mr. Greg Stratton April 4, 2001 Page 2 Thank you for this opportunity to be of service.

Firemen finished flushing the diluted gasoline into the city storm drain and sewer system. Firemen also used chemicals to break down the fuel and make it less likely to explode as it mixed with water. Fire Capt. Bill Callaway said the danger of an explosion or flash fire was "extremely high" when firemen first arrived on the scene, but the danger dissipated almost immediately when "several thousand" gallons of water were used to wash the fuel away, Callaway said. The line was repaired shortly after the incident and the street was only blocked about 45 minutes. l � ��I ,!�Ilil� �t + ,,,• City of SM Luis OBISPO FIRE DEPARTMENT 748 Pismo Street Y San Luis Obispo, CA 93401 • 805/543-6046 9 PIay 1975 Press Release At approximately 1-015 this morning, we received an emer_gencT•r call that gasoline vias flowing down the gutter of the intersection of I--Iiguera and Madonna. On arrival at the scene, vie determined that gasoline was being washed down the gutter from the Beacon Station at 174 Higuera. The (,%later Quality Control Board vias contacted and their agent advised us that under the circumstances that it would be okay to flush the remaining gasoline into the drainage system. According to Al Brawley, station manager, the spill was caused by the tank truck operator leaving his truck unattended during the filling of the station's tanks. The tank filled and by the time the driver was able to shut the fuel off, we extimate as much as fifty (50) gallons vias spilled on the ground. The station manager, unaware of laws prohibiting flushing flammable liquids into the street, creeks, or drains, used a garden hose to flush the spill into the street. The Fire Department has contacted the State Fire Marshal's office and has requested action against Al Ramos, the tank truck operator, of Hanford.

They stated that your department was the responding agency and that they had not received notification until approximately 6:30 p.m. April 14th. In the future, this office would greatly appreciate notification if a pollutant enters the creek, or if the possibility of a discharge exists so we may also respond and issue citations if necessary. I realize that your department is more than willing to cooperate with our agency concerning matters such as oil spills. I further realize that your department was not know- ledgeable of the Coast Guard's responsibilities and, hopefully, this letter will clarify our duties.

Although one large leak was dis- covered(and corrected) in an underground gasoline storage tank at one service station, this does not preclude the possibility that there are other leaks in this area contributing to the problem. This pos- sibility has become increasingly important in light of continuing gasoline infiltration into the sewer system with attendant explosive vapor readings at manholes along Monterey Street some four weeks later. For this reason, and in accordance with San Luis Obispo Municipal Code, particularly Uniform Fire Code Sections 1.210, 1.216, and 15.110, all pro- perties within this general area that presently store products similar to gasoline, or have done so in the past, are being directed to have appropriate tests made to ensure against any possible leakage contributing to this problem. Within thirty(30) days of receipt of this letter, complete all tests in National Fire Protec- tion Association Pamphlet #329-19721 "Recommended practice on underground leakage of flammable and combustible liquids" as specified in pages 329-22 through 329-29. For any underground storage tanks not presen- tly in use, furnish proof that procedures specified in Uniform Fire Code Section 15.205(1971 edition) "Abandonment of tanks" have been completed. } Gasoline Storage 22 August. 1973 Page 2 All tests are to be witnessed by Fire Department Representatives.

Williamson, Assistant Administrative Officer FROM: Lee M. Schlobohm, Fire Chief SUBJECT: Gasoline Leaks From Service Stations In accordance with a recent comment by Mayor Schwartz that a progress report on the various gasoline leaks discovered in the vicinity of Monterey Street would be appreciated by the City Council, the following information is provided in the event you feel that this would be of interest to them: 1. Monterey Street at Pepper - The "Economy" Service Station on the S.W. corner is owned by the Gulf Oil Company, which voluntarily replaced underground fuel tanks following tests on July 24, 1973 which indicated that one or more of the tanks, or the underground product piping, was losing fuel and was possibly the source of the presence of explosive gasoline vapors in the Monterey Street Sanitary Sewer at Pepper, Johnson, and Toro Streets. According to Gulf Oil Company Representatives, the tanks removed from this location were subsequently tested and were found to be free from leaks and satisfactorily passed pressure tests. At this time, therefore, there is no way to prove or disprove whether the cross -threaded connection on the fill opening, or other possibly leaking joints or connections to the tanks, pumps, or dispensers was responsible for the apparent loss of fuel during the tests made July 24th, or for the explosive concentrat- ions of flammable liquid vapors found to be present in sanitary sewer manholes at the three intersections mentioned. Although possibly explosive concentrations of flammable liquid vapors are still present at all three locations, readings are at lower levels only, and the absence of high concentrations of vapor at street level would seem to indicate that'the hazard to pedestrians or passing motorists is relatively small. 2. Monterey Street, County Garage, near Santa Rosa - The gasoline tank located underneath the concrete rloor o- �h-_ unt`' q?r'n_' was estimated to be lea i.ng fuel a- to rate o- one or tUo;o gallons per day. County officials responsible for maintenance Mr. D. Williamson Gasoline Leaks from Service Stations November 27, 1973 Page 2 and operation of service facilities at this location were very cooperative and complied quickly with Fire Department requests that the tank be emptied of fuel and removed from service. Rather than having the leaking tank physically removed, however, the Fire Department approved a county proposal to temporarily abandon the tank, fill it with water, and re -check the level each week to determine the exact amount of liquid lost per week. This tank will be physically removed at such time as the county garage is demolished or re -modelled. 3. Monterey Street at California Blvd. - The Mission Gulf Service Station on the N.W. corner of Monterey and California Blvd. was found on November 16, 1973 to be 'leaking gasoline into the storm sewer at this location. Two test holes were bored adjacent to the concrete box culvert on the side toward the under- ground tank location, and gasoline was discovered at the 6 foot level. Mr. Harry Kaplan (property owner) retained the Neilson Construction Company to uncover one of the product lines between the tank and pump islands. This line was found to have a number of large holes. Based on this discovery, the Fire Department requested that the owner replace all product lines at this time, since all have been in service for 17 years and failure to replace all lines could result in additional leaks at some future date. The owner agreed to the request, and the Neilson Construction Company is in the process of replacing all product lines and testing underground fuel tanks for possible leaks. Permit forms for installation of flammable liquid tanks at service stations have been revised and will be utilized as of November 28, 1973. (copies attached) 4. Monterey Street at Johnson Avenue - The Arco Service Station on the S.E. corner of Monterey Street and Johnson Avenue has been suspect for some time as a possible source of the intrusion of gasoline into the sanitary sewer on Monterey Street, but no proof exists at present that the condition of underground gasoline tanks and/or product piping is indeed responsible for the presence of hazardous concentrations of flammable liquid vapors consistently found in the sewer manhole Mr. D. Williams(.__ Gasoline Leaks from Service Stations November 27, 1973 Page 3 at this -,location since July 24, 1973. Several weeks ago, the Gulf Oil Company obtained a City Permit to bore several test holes along Monterey Street. The test hole (6-89) on Monterey Street in front of the Arco Service Station was found to have liquid gasoline floating on the water, and the possibility that a gasoline leak exists at this location seems to now be a strong probability. In order to carry out the City's responsibility to provide citizens with an adequate level of safety from the hazards of fire and explosion, it is my recommendation that professional testing of the three underground gasoline tanks and product piping at the Arco Service Station at this location be ordered without delay. I would specifically recommend that the tests be performed by the Dialysis Company, 17151 Sherman Way, Van Nuys, California. This company has recently performed similar tests on tanks at the Hessler Union Station, Monterey and Johnson, San Luis Obispo. Lee M.

Matthews #3147 At approx 1540 hre, date, the U/S was dispQtched to the intersection of Monterey and Johnson Ave, this city, in response to a report by the Fire Dept that an auto had been involved in a fireat that location. Upon arrival the U/S contacted a Mr. Robert I1. NEILL, who resides at 691 Grove St, this city. DDL #:.")049364. Mr. IZETLL is the owner of the 1970 Chevy Corvette Lie 024 ATV, which was involved in the fire. Mr. NEILL related that he had parked his veh at the south curb in the 1200 blk of Monterey St, and had gone for a test-drive in &aother veh from they auto sales lot at that location, and during his absence, the veh had been involved in a fire. The cause of the fire was determined to be gasoline in the gutter of the 1.200 blk of Monterey fit, which had been pumped from the manhole located at the intersacntion of Monterey St and Johnson Ave by a Pacific Telephone and Telegraph crew, headquartered at 2135 Parker St, this 'city. A MR. Dwight STEVENS, wbo resides at 5020 Cslle Rios, in Rolling I Ills, 543-4143, had been in charge -3f the crew at the time of the fire. 4R. Stevens related that they were pumping water from the manhole, in order that they might get access to their underground cable at that location. He stated that all of a suden, that the small pump which they were using, ceased to function, and backfired, ac whic'► time it ignited gasoline, which they had apparently pumped from an art:, where it had settled within, the sewe-r system of San Luis Obispo city. The backfire caused they ignition of the fuel, which continued to run down tha 1200 blk of Monterrey St, in an ignited condition. Upon reaching the area where the owner of the above vehhad parked It caosedckmage to his tires on the right side of the veh, as well as paint daauage to the right side of the veh. No other damage appeared to have been sustained. It should be noted that fire equipment OW personnel,�ere at the location at the time of the U/S's arrival. They stated that they had previously thought they had a leek in that area contained, however, they apparently had been mistaken, as the gasoline had settled to the bottom and withwater running over it, had not been detected::"ifl the water had been pumped from the surface. It should be noted the Stevens veh 'was bcAtad approx 10$' wast of the wastcurb of Johnson Ave, in the 1200 bW. of Monterey St, andapprox 1' 4" from the south curb of the 1200 blk of Monterey St. At this time there was no further details or information.

The three underground gasoline tanks at Chuck's i'.conomy Service Stations r►onterey and Pepper Streetsq have been replaced# and the new tanks and product piping are apparently leak-froe at this time. 2. The underground gasoline tanks at the Mission Gulf Service StationlCalifornia and Monterey Street) have been teatedg along with the new product piping ordered to be installed at this location following discovery that the ex— isting pipe lines were leakingg and all parts of the under jround system are apparently leak — free at this time. 3. The underground gasoline and product piping at the Arco Service Station* Monterey and Johnson, were tested by the dialysis Company on December 20t 1973 and it was determined that several leaks required corrective action. The necessary repair work was completed on January 15, 19749 and the tanks and allied piping are apparently leak —frees at this time. 4. The underground gasoline tanks at Hessler's Union Service Station] Monterey a►nd Johnson were tested by the Dialysis Company on August 239 19731 and it was determined that no leaks existed at the time and apparently the tanks are still leak —freer at present. Memorandum 17 January 1974 Page Z ReerCent teg::s Conducted key City Public Works Foresnan, William Harris (January 72 and January 16U, copies attached) indicate that all sewer manholes on Monterey Street are free of flamm- able liquid vapors at present, since tests show "Zero" read- ings on both dates.

I trust that City Administration joins sea in mwy feeling that succesSful elimination of the potential hazard to citisens and to they sewer systemp which first became apparent in July, 1973, has been satisfactorily accomplished as the result of patient and methodical identification of the various sources of contamination and the necessary follow-up work required for the elimination Qf all ryas lesaKs in this particular area.

City Fire Marshal Don Sylvia said today it is his opinion the gasoline, which testing has indicated is more than a year old, is from leaks found at the Cuesta Station at Monterey and Pepper streets and the Gulf Station at California Boulevard and Monterey in the summer of 1973. He said both leaks were repaired in 1973, and the gasoline which caused a minor above ground explosion last week, and has penetrated telephone company conduits, is old fuel. Meanwhile telephone service is ex- pected to be resumed late today to the area which had been cut off. Telephone company crews began stringing a temporary overhead line Wednesday, bypassing the Johnson Avenue and Monterey Street in- tersection where the damaged lines are. A consultant, touted 'as "world renowned" by fire officials, has been flown in from Chicago to advise the fire department and telephone company on ways to eliminate the gasoline. John Ainlay arrived in San Luis Obispo late Tuesday night and began testing the fuel Wednesday. Ainlay, who said his services are paid for by the Western Oil and Gas Association, said he estimates there are between 300 and 500 gallons of gasoline still in the ground, but it does not present any danger below the street surface. A pump has been installed about 100 feet east of the telephone company manhole where the gasoline was discovered and pumping operations to expel the fuel began this morning. Sylvia said special pumps have been brought in to separate' th4- gasoline from the water. He said the gasoline would probably be stored in drums and used for fire department training exercises in the future. Earlier this week the telephone company pumped out about 4,000 gallons of mixed gasoline and water and transported it to a special dump site at Casmallia. It cost about 50 cents per gallon to dispose of the liquid in addition to transportation casts. Ainlay said the major concern today is to flush out the telephone company manhole to allow crews to repair damaged lines. He said he expects the entire operation to be over within a week. r n ,.r.

Gasoline leak found By Mark Gladstone and Mee Durant A leak in 4 12,000 - gallon gasoline tank at Chuck's Econ- omy station. 1371 Monterey St., Santa Maria, during the night. City officials thatched the situ- ation throughout the night after closing Monterey Street from Santa Rosa Street to Pep- ryw• Rfwm talking with Mayor Kenneth Schwartz.

City Fire Marshal Don Kaye said the leak was discovered in the tank shortly before noon today, and pumps immediately began emptying it. The fumes were discovered Monday along a four -block section of Monterey Street and reached crisis proportions Thursday night. The street was ordered blocked. Kaye said the tank, after be- ing neutralized by dumping 200 pounds of dry ice into it, would have to be dug up at the own- er's expense and replaced by new storage units. He said the ice would be poured in later today. Meanwhile, other prevention. } measures along the street would continue as long as evi- dence of the hazard continues, Have said. The leak was pinpointed by M filling the suspected tank with gasoline and then monitoring it to see if the level inside fell. Cite officials said the gasoline shortage hampered the check. "All of a sudden the Fire D;.- psrtment is affected by the gas slortage." Fire Inspector Ralph Hunt said this morning. He indi- cated the gasoline, not available 1 locally, had to be trucked from The street was �upened to traffic at 6 a.m. today only after the Public Works Depart- ment: and Water Department workers fiIIed the sewer line with water to reduce the chance of an explosion. During the night the city had moved to: —Flood the sewer lines. —Use blowers to dissipate gas fumes. —Check for any bottlenecks in the sewer system where gas might back up. These actions were taken because sparks from passing vehicles or pedestrians could ig- nite the fumes. The result could be flying manhole covers or a serious rupture in the sewer system, fire and street cave-ins, possibly causing injury and loss of life, according to Fire Mar- shal Don Kaye. At a midnight session last night city staff members spoke in somber tones. "We just can't take a chance on the thing," said City Clerk .lean Fitzpatrick, acting city administrator. City Administra- tive Officer Richard Miller was out of the city. Fitzpatrick) authorized depart- ments to call back as many men as necessary to help ease the situation.

This leak amounted to just over one thousand gallons since January. This Department has been pumping sump tubes that were placed in the ground just fat the purpose of recovering as much of the fuel as possible. On 15 November 19769 a meeting was held at City Hall in San Luis Obispo with the interested parties. This Department went on record stating that we feel the hazard to life has been abated and we are no longer involved with the recovery of gasoline in this area. This letter is only to keep you abreast and informed of our actions in an area that you may have some concern. If you have any questions, please feel free to contact me. Sincerely, Mikel J.

Park, Fire Marshal SUBJECT Gasoline Leak on Monterey Street Prior to my arrival as Fire Marshal to the City of San Luis Obispo, the City had a problem with gasoline appearing in the telephone vault at Monterey and Johnson. This later influenced the Fire Department, in cooperation with Gulf Oil and the telephone company, to run tests of the soil in the area between Johnson and Pepper on Monterey. As an outcome of their testing, they installed a drain line in front of the Cuesta Station down to a sump located near Johnson on Monterey. After my arrival as Fire Marshal, this was one of the first problems brought to my attention. It was my job to witness the test on the new piping that was being installed in the Cuesta Station in hopes of eliminating the leak. It was my opinion, at the time, that the test be applied not only to the new plumbing, but also to the existing tanks. The test consisted of measuring the fuel in the tank before and after the test to note any change in the liquid level. The test itself was five pounds of air pressure applied to the tank and plumbing. The results were as follows: Regular gasoline; time of test 0632 to 0755 hours. Liquid level before 55 inches, after 55 inches. Lost h pound, leak was found at the gauge and repaired, no loss afterward. Premium gasoline; time of test 0822 to 0919 hours. Liquid level before 52 inches, after 52 inches. No lead gasoline; time of test 0932 to 1047 hours. Liquid level before 50-7/8 inches, after 50-3/8 inches. There was a difference in the depth of the fuel, however, this could have been due to the fact that the gauge was hard to read as far as the eighth fractions. Even though we had an appreciable difference in the amount of depth of fuel, later in the report I think we will prove that this has no bearing on the problem. Memorandum 23 June 1976 Page 2 In the first part of May of this year, Bill Dugger, from our Department pumped 14 gallons of gasoline out of the hole after four days of draining. This month, after four days of draining, we were able to get 7h gallons of gasoline. This shows a drop of approximately 50% in the amount of fuel gathered from the sump hole in the last month. On 23 June 1976, I had a meeting with Mr. Henton of the telephone company. He seemed, still somewhat upset with the problem and stated that he wished to do more than just wait it out. I informed him that the Fire Department would be glad to cooperate in any new ideas or methods in securing an end to the gasoline problem. He showed me two reports that he received from Truesdale Laboratory in Los Angeles. Their report showed that they could not tell what brand of gasoline, however, they were able to tell that the grade was premium. I would like you to look back at the test results on the tank of the Cuesta Station. There was no leak of fuel or loss of air during the test on the premium tank which was held for just over an hour's time. In summary, I would like to state that everyone involved has done everything that they could do in order to eliminate this problem. We at the Fire Department would be more than glad to assist though, in any method or procedure that would bring this to a speedier end. The telephone company has expressed a possible desire to continue the soil testing in the area and examine the topography to check on possible rock formations that would help us determine the exact location of the leak or pocket of fuel, if one exists. Again, I assured them we would cooperate in any way possible. This report is intended to keep you informed,of where we currently stand with this problem. cc: Miller Romero Hird i n1 2 l i ,• o �c �S� h 2�J 3 s� ..r a E i= �0 JANUARY 26 Completed the drain in front of Arco, Monterey and Johnson.

Upon arrival, we determined that the toilet was overflowing because City crews • were flushing the sewage system. However, there was an odor of gasoline and upon talking to the City crews at Monterey and Pepper, they confirmed that they also noticed gasoline in the sewer. The sewer in question runs from near the property line between Karleskint-Crum and the service station and as such, gasoline must be entering at some point in that block of Monterey between California and Pepper. The City crews, under Myron Torik, advised me that they would thoroughly flush that line and I suggested that we check the main hole at Monterey and Pepper the first part of this next week to see if any additional gasoline was entering the pipe. It may be that the gasoline that we found Wednesday is residual from our past underground leaks, but it may also be that we still have a leakage problem in that area and as such, should check Monday. -- Jim Petroni, Inspector city of san luis OBISPO TO—;rm ,DATE FROM SUBJECT J,bo" eee MEMORANDUM cr of sAn Luis OBISPO allTo '11-ril C-/j I - '78 &me F FROM TA ache'v SUBJECT 41 Mar„. �- �G�-GLi,2 ✓� �a � 7- c- . t (l a-c/-i e i- MEMORANDUM ('Ity O� SAn LUIS OBISPO FIRE DEPARTMENT {p E 748 Pismo Street ■ San Luis Obispo, CA 93401 • 805/543-6046 5 December 1978 Steven D.

Mr. Dewar and the Gulf Representative re- quested that they be allowed to pressure test the storage tanks while still containing gasoline. They further claimed that it would take several days to pump the gasoline from these tanks. I emphatically denied their request to pressurize the storage tanks while containing gasoline and explained that if the leak does in fact come from one of the tanks, any pressuri- zing will either; 1) Force a larger quantity of gasoline into the ground and thereby to the sewer systems, and; 2) Might also cause a major rupture of the tank causing a totally uncontrollable large loss of gasoline intq the under- ground stratas. I further attempted to explain my opinion as to the potential liabilities that might be incurred by their actions in this matter, and informed them that it was my understanding that equipment is MEMORANDUM 25 July 1973 Page 2 available to pump these tanks in one or two hours time. I related Inspector Alstots order that the tanks will be pumped dry without further d c1_ay, but that they could immediately begin pressure tests of product piping as long as it did not pressurize tanks. Received a call about an hour later that a truck had been arranged for from Santa Maria that would pump the tanks dry in about one (1) or two (2) hours.

Fire Department Representatives are working with all properties within this immediate area having known on -site storage or use of gasoline in an attempt to locate the source of the leak. Other personnel are periodically washing down the sewer and storm drain, and twice a day all buildings served by this section of drainage system are inspected for possible explosive concentrations of gasoline fumes. At this time I believe the following steps should be taken without delay; 1. If all the attempts of the Public Works Department to seal all manhole outlets to prevent vapor loss are unsuccessful, the Police Department should immediat- ely detour all vehicular traffic and other sources of ignition from this two block area in an effort to prevent ignition of the extensive gasoline fumes emanating :from the manhole covers. .a CITY 0:9 SAN IUIS oinsnipo j F 748 Pismo Street - 543-6046 I R E D E P A R T M E N T 26 July 1973 (� I MEMORANDUM TO: File FROM: Don J Kaye, Fire Marshal SUBJECT: Monterey Street Gas Leak, Emergency Meeting MIDNIGHT Fire Marshal Kaye, with the approval of Mayor Schwartz, called an emergency meeting of the follow- ing staff personnel to determine if there were any acceptable alternatives to Fire Marshal Kaye's action of barricading off the streets of this imme- diate area in an attempt to minimize the potential ignition of explosive concentrations of gasoline vapors coming from the sewer manholes in the 1200 and 1300 blocks of Monterey; Chiefs Schlobohm and ,p Rodgers, City Clerk Fitzpatrick, City Attorney Shaw, Q;Yy City Water Director Paul, Acting Battalion Chief Hall, Inspectors Alstot and Hunt, and Fire Marshal Kaye.

Toh lobohm, Fire chief Dom J, Kaye, Fire Marshal Monterey Street Gasoline Leak 1230 hrs. 26 July 1973 As you know, the leaking tank was identified a short time sago. A otan., by truck immediately began pumping all product from the involved tank - expected completion, approximately 1500 hours this date. I advised Mr. Dewar that it woula be necessary for him, immediately upon emptying the tank, to drop 200 lbs. of dry ice into the tank and completely purge it with CO2 to remove all residual gas fumes, and securely capb I called City Engineer Romero to the scene, showed him the location of the involved tank, and requested that he take all appropriate steps Possible to reduce or eliminate further gasoline intrusion at Monterey Street., Inspector Alstot was left at the scene with instructions t directly witness the total removal of all flammable liquids and combustible vapors from the involved tank. Mr. Dewar was further advised that it was my opinion that as a result of our relatively recent history of product storage and delivery system failures at this facility, the condition of all underground storage tanks is immediately suspect. Mr. Dewar agreed. Further action in this respect appears appropriate, and necessary, I would strongly r ec osmnend that the fo l lowing actions be continued by our department until such a time as all gasoline vapor readings are eliminated in the area of concern; 1. Deluge flushing of the sewer main. Continue, 24 hours a day as necessary, to keep the vapor readings at a safe level below the lower explosive limit of gasoline. At the present time, both the vapor readings and deluge flushing are being done by our people using the Public Works Dept. detector and the hydrant at the corner of Monterey and Pepper Streets 2. Vapor readings at all interior terminals of buildings served by the involved sewer line be continued on a twice -a -day basis as long as vapors are present in street manholes. All building occupants should be advised each time that it is extremely important to maintain adequate water levels in all "P" traps of these buildings. 3. Any further occasions when deluge flushing fails to oontrol vapor reduction below the lower explosive limit of gasoline, and actions by any other City agency are unsuccessful in eliminating this vapor exposure on the street surfaces, area streets must again be barricaded and patrolled to minimize any potential ignition sourced Respectfully submitted, D Fire ;arch el cos Mayor City Administrative Officer City Attorney City Dater Directw PW a 'C3 i.' 61 CU •d L•1 v 'L7 y R7 cc!
