Pictures start at 7AM the same morning. PSE power pole destabilized see 2nd picture below. Blue arrows are flow water. Total estimated water flow was 10,000 gallons per the lead Bellevue Water Utilities managers on the site that morning. In X = storm drains overwhelmed with 10,000 gallons of water flow. Imagine what 280,000 gallons of jet fuel from PSE’s EE inducted Olympic pipeline break will look like. Via induced stress corrosion during operation or via damage during construction. The later is exactly how this Olympic pipeline broke in Bellingham in 1999 with 280,000 gallons lit on fire in remote area. Stress corrosion is how the Williams 30” natural gas pipeline blew up twice in 2003 in WA. comparison the last break in Olympic pipeline in 1999 spilled 280,000 gallons for which the fire wall was hundreds of feet high and the smoke plume reached 35,000 feet. The source of the 6” water main break operating at 150 PSI pressure at the intersection of SE 46th St and 149th Ave SE Bellevue WA 98006. A significant portion of the water went under the street until it resurfaced ~200 feet later at a power pole almost at the intersection of 148th Ave SE 20170917_074631.jpg 20170917_085000.jpg Water breaks through the side of the street at a power pole show 200 feet from pipe break. Water pipe operating at 150 psi verse the Olympic pipeline which operates at 850psi. See curbs and gutters undermined or completely pushed down hill. 20170917_080508.jpg Storm drain clogged with rocks on SE 46th St Bellevue 98006 looking WNW to 148th Ave SE. Notice how far up the lawn the 10,000 gallons of water flow went form a 6” pipe. Imagine what 200,000 gallons from a 20 inch would look like. 20170917_085148.jpg Same drain the next day after it has the rocks and debris removed. Notice the curbs have dropped 4inches relative to the lawn and street has dropped an inch relative to the dropped curb and the storm drain itself has dropped 2 inches relative to the street, or 7 inched relative to the lawn. This side of the street had 2 feet of soil and rock washed out for ~200 feet entirely under the pavement. This pavement was torn up as can be seen right below and the two foot gap filled as can be seen two pictures below. 20170918_104745.jpg View looking up SE 46th St from 148th Ave S toward the source of the water break. Notice the removal of the street starting and the 2foot sized rock at the curb by the fire hydrant. Also the 6 inch high pile of mud and rock yet to be scraped away with a front lo ader. 0170917_074326.jpg The replacement power pole is in and power and comms lines being moved. 20170917_080036.jpg Two feet of material that was eroded away for 200 feet by 10,000 gallons of water is starting to be filled in. 20170918_104854_Burst01.jpg The ~30 hours after the break and after 200 ft of street were ripped up and the 2 foot erosion road bed was filled with gravel. A new PSE power pole is already put in place. Photo is facing up hill on SE 46th St to where 6 inch water main broke. Lines in picture are due to file corruption in camera. I have several other photos but not as detailed with gravel and massive curb damage and PSE pole all in one photo. 20170918_104804.jpg Same day of break 7 hrs later at 150 Ave SE and SE 44 ST 20170917_080508.jpg 150 Ave SE and SE 43rd PL 7 hours after a 10,000 gallon 6” water main break. 20170917_080320 This is a close up of the debris that the above street sweeper is removing at 150 Ave SE and SE 43rd PL. The debris above was carried away from the break of a 6 inch water pipe break 700 feet away. For scale of the shoe seen is 5.25 inches wide. 20170917_080336.jpg Interection of SE 43st and 150th Ave SE. See the still large amount of flow debris and one inch rocks in the mud, but now 1500 feet from 6” water pipe break. Same size rocks as in the above picture as thos with 4.25 wide size 11.5 shoe in picture . 20170917_080508.jpg Intersection of Newport Way and 150 AVE SE facing north. Notice how the water from a break of just 10,000 gallon completely flooded this intersection and turned to the left in the picture travel at least another half a mile as well as a major portion continuing down 150 Ave SE also for more than a 0.5 mile to I90 freeway. 20170917_080620.jpg Viewing looking southeast up hill at intersection of 145th Ave SE and SE 42nd PL Bellevue, nealy a mile away from the break and several flow branches later and past over by passing over +30 storm drains for this branch of water flow. See the size of water flow debris and mud about 7 hours after the break. 20170917_081458.jpg intersection of 145th Ave SE and SE 42nd PL facing west downhill. 20170917_081527.jpg And 20 feet farther west we see the above water flow with 80% of the water flowing to the west (and south) of the street side by passed this storm about a mile away from the source break.20170917_081541.jpg This water flow tracks on the eastside of the street at bend of SE 42nd Pl and 145th Ln SE. Water flow one mile away from the source of the 6” water pipe break at SE 46th St and 149th Ave SE. The main branch of the flow went on the west side of the street. Opposite this picture The next day and many days of vacuuming rocks and debris from the storm drains. Just 10,000 gallons now think 200-300,000 gallon of jet fuel from a Olympic pipeline break caused by a 120 to 180 increase in stress corrosion on the pipline from new steel poles twice as high and 2-3 times greater spacing carrying 2 circuits (6 wires) not 1 (three wires). See pic below Notice the amount of gravel left on the grass for the 10,000 gallons flowing down 150th Ave SE and how far it went above the curbs. 20170918_104420.jpg Nov 17 2017 the finished replacement of SE 46th St P1100407.jpg The BP pipeline Safety patrol plane. P1100415.jpg P1100417.jpg See Pipeline Patrol marked under plane. Tail number N714OK. Did they say in the EE EIS that this plane’s job is to direct evacuations of neighborhoods not to direct firefighters for any fighting?? Any +1000 gallon fuel fire in the densely populated areas is unstoppable. In hilly area fire foam is worthless. Fire fighting foam (AFFF) is toxic long term while life saving near term. On a sloped terrain this Navy fuel fire expert will tell you is that fire foam will be worthless and will be reserved only for evac purposes if not just for the firefighter themselves given the miles long conflagration of a Olympic pipeline and its expected past release 237,000 gallon (280,000 from other rpts) jet fuel/ auto gasoline leak. PSE EE EIS states the maximum could be as high as 372,162 gallons per page 330of 451(or page 4.9-14). Any one know why he flys the pipeline every week or so? P1000892.jpg
