Pipeline EAP · Before the Call

Olympic Pipeline Explosion — Whatcom Creek, Bellingham

Whatcom County, Washington · June 10, 1999 · 277,000 Gallons of Gasoline · Three Lives Lost

Pipeline EAP Caller Recognition EAP Notification Failure Hazmat Infrastructure Failure Washington State
For ninety minutes, residents called Whatcom County 911 reporting a strong gasoline smell near the creek. Callers said the water had turned pink. A fly fisherman had gone quiet. Two ten-year-olds were playing near the water. The pipeline operator's SCADA system had been showing a pressure anomaly the entire time. Nobody called the PSAP. When Olympic Pipeline finally contacted the fire department dispatcher at 4:57 PM to report a "possible release," the creek had already been on fire for two minutes.

Section 1 — The Situation

What Was in the Ground Under Whatcom Falls Park

Before you can understand the dispatch problem, you need to know what was running beneath that park — and what the regulatory framework was supposed to require when it failed.

The Pipeline
The Olympic Pipe Line Company operated approximately 400 miles of pipelines transporting refined petroleum products — gasoline, jet fuel, diesel — from refineries in northwest Washington south to terminals in Seattle and Portland. The accident pipeline was a 16-inch diameter steel hazardous liquid line carrying gasoline from an ARCO refinery near Cherry Point through Whatcom Falls Park, directly beneath Hanna Creek and Whatcom Creek, on its way south. It was moving approximately 7,000 gallons per minute when it ruptured. The pipeline control center was located in Renton — not in Bellingham.
What the EAP Required
Under PHMSA regulations in effect in 1999, pipeline operators were required to maintain emergency response plans and to contact local emergency services when a release was detected. Olympic Pipeline's SCADA system registered a pressure anomaly at approximately 3:25 PM. Controllers initially shut down the line — then restarted it at approximately 4:15 PM, pumping thousands more gallons into the creek. The first contact to emergency dispatch came at 4:57 PM — two minutes after the explosion. The EAP notification chain that should have run from SCADA alarm to operator to PSAP never functioned. The PSAP was not in an active EAP notification posture at any point before ignition.
⚠ The Regulatory Gap This Incident Created
In 1999, there was no federal requirement that pipeline operators directly and immediately notify the PSAP when a release was detected. The Bellingham explosion was a primary driver of subsequent PHMSA rulemaking that now explicitly requires pipeline operators to immediately notify the PSAP serving affected communities when there are indications of a pipeline facility emergency. That rule exists because of what happened in Whatcom Creek. The incident also directly created the Pipeline Safety Trust, the national pipeline safety advocacy organization founded by the families of the victims.

Section 2 — The Dispatch Timeline

What the Comm Center Saw, and When

This timeline is told from the console. Watch how the information available to dispatchers differs from what was simultaneously known at Olympic Pipeline's control center in Renton.

3:25 PM — Rupture Occurs
The 16-inch pipeline ruptures in Whatcom Falls Park near the Whatcom Falls Water Treatment Station, damaged by a construction crew in 1994 that struck the pipe and never reported it. Gasoline begins flowing into Hanna Creek at approximately 7,000 gallons per minute. No notification to the PSAP. No notification to anyone outside Olympic Pipeline. The SCADA system registers a pressure anomaly. Controllers shut down the line to investigate.
~3:30 PM — First 911 Calls Begin
Residents and businesses near Whatcom Creek begin calling the Whatcom County 911 Dispatch Center reporting a strong odor of gasoline in the vicinity of the creek. The callers do not know what is causing the smell. They report it as an odor — not a pipeline emergency. The PSAP begins receiving what appear to be isolated reports of a gas smell near a park.
~4:15 PM — Operator Restarts the Line
Olympic Pipeline controllers, having shut down the line to investigate the pressure anomaly, restart the pumps — adding thousands more gallons to the creek. This decision is made at the Renton control center, 90 miles from Bellingham, while 911 calls about gasoline smell are actively being received by Whatcom County dispatch. The two information streams are not connected.
~4:24 PM — Caller Reports Creek Discoloration
A woman driving across the Woburn Street bridge over Whatcom Creek calls 911 reporting an odor so strong it makes breathing difficult. A resident near the creek calls to report a strong petroleum odor and discoloration of the creek water. An Olympic Pipeline employee in Bellingham independently calls the Woburn Street bridge and calls both 911 and the Olympic control room in Renton to report gasoline fumes. The control room begins closing valves to isolate the rupture.
4:29 PM — SCADA Alarm Activates at Control Center
Olympic Pipeline's leak detection software formally activates an alarm in Renton. Controllers begin closing mainline block valves. No call to the PSAP. No call to Bellingham Fire or Police. The PSAP is still receiving public calls about odors and a discolored creek, working without the context that a major hazardous liquid pipeline has just ruptured beneath the park.
~4:34 PM — Fire Department Dispatched to Investigate
Based on accumulating public 911 calls, Bellingham Fire Department dispatches a Hazardous Materials Team to investigate the odor reports near Whatcom Creek. This is not an EAP activation — it is a standard hazmat investigation response to caller reports. Responding firefighters have no advance information that a pipeline rupture has occurred or that the substance involved is gasoline in explosive concentrations.
~4:45 PM — Hazmat Team Arrives, Finds Gasoline Flowing in Creek
Bellingham Fire Department Hazardous Materials Teams arrive at Whatcom Creek and find copious quantities of gasoline flowing down the creek toward Bellingham Bay. The water is pink. The fumes are overwhelming. This is the first moment the PSAP and responding units have a clear picture of what they are dealing with. Bellingham Fire and Police immediately begin evacuating the area and setting up barricades. The fire department notifies Olympic Pipeline that gasoline is flowing down Whatcom Creek. It is too late.
4:55 PM — Ignition
Two ten-year-olds — Wade King and Stephen Tsiorvas — playing in the park near Hanna Creek find an old butane lighter and flick it. The gasoline vapors, which have accumulated to explosive concentrations for nearly 90 minutes, ignite. A fireball races 1.5 miles down Whatcom Creek. The temperature exceeds 2,000°F. Liam Wood, 18, fly fishing upstream, has already drowned — overcome by fumes and fallen into the creek before the explosion. The two boys sustain burns over 80–90 percent of their bodies. Both die the following day at Harborview Medical Center in Seattle.
4:57 PM — Olympic Pipeline Calls the Fire Department Dispatcher
Olympic Pipeline operators contact the fire department dispatcher to report a "possible release of product into Whatcom Creek." The creek has been on fire for two minutes. The PSAP is now managing a mass casualty event, evacuation coordination, hazmat response, waterway closure, and a search for victims — simultaneously. Interstate 5 is closed. The Coast Guard closes Bellingham Bay. Gasoline has migrated into the city sewer system.
5:20 PM — Hospital Alert Issued
St. Joseph Hospital in Bellingham issues a staff alert after the fire department dispatcher advises hospital staff of the fire. The hospital prepares to receive a large number of patients and notifies Harborview Medical Center Burn Center in Seattle. The Whatcom County Sheriff's Office responds with 15 deputies. Washington State Patrol, Western Washington University Police, and Ferndale Police Department all respond to assist. The incident is now a full multi-agency event that will take hours to stabilize.

Section 3 — Know What's in the Ground

Pipeline Mapping Resources for PSAPs

The central training lesson from Bellingham is that dispatchers were working blind — they had no awareness that a major hazardous liquid pipeline ran beneath that park until gasoline was already flowing in the creek. These tools exist so your center doesn't start from zero when the calls come in.

PHMSA · U.S. Department of Transportation
National Pipeline Mapping System (NPMS)
The NPMS is the federal database of hazardous liquid and gas transmission pipelines in the United States, maintained by the Pipeline and Hazardous Materials Safety Administration under the U.S. DOT. It shows you what is running through your jurisdiction — who operates it, what it carries, and who to contact. There are two access tiers: a public viewer available to anyone, and a more detailed system for government officials.
What Your Center Should Do with These Tools
Pull up the NPMS Public Viewer for your county right now. Look at what's running through your jurisdiction. For every major transmission pipeline you see, ask: who is the operator? What is the emergency contact? Is your center listed as a named PSAP in their EAP? Are you in the NENA PIPE database so they can reach you directly? The Bellingham incident happened in part because the pipeline operator had no direct, verified contact path to the PSAP. That gap is closable — but only if your center knows the gap exists.

Section 4 — The Decision Points

Where Dispatcher Judgment Mattered

The Bellingham incident is fundamentally a caller recognition problem compounded by an EAP notification failure. The decision points below are where the dispatcher had choices — or where the system gave them no good choices at all.

The first 911 calls at 3:30 PM reported a petroleum odor near Whatcom Creek. This is ambiguous in isolation. Callers near waterways sometimes report fuel smells from boat traffic, spills, or stormwater. Without pipeline awareness, a dispatcher has no framework to evaluate whether this is an isolated nuisance or the beginning of a catastrophic industrial event.

The question this raises for your center: What is your protocol when you receive multiple calls about an unexplained odor near a waterway or green space? At what call volume or geographic concentration does it trigger something beyond a standard hazmat investigation? Is there a query built into your CAD that prompts the dispatcher to check whether a pipeline corridor runs through that area?

In Bellingham, the accumulation of calls over 90 minutes eventually triggered a hazmat response — but the response came from call volume, not from any framework that recognized what was likely happening. The difference between those two paths is the 90 minutes.

At approximately 4:15 PM, Olympic Pipeline controllers in Renton made the decision to restart the pumps — adding thousands of additional gallons to the creek — while Whatcom County dispatchers were actively receiving calls from the public about gasoline smells near that same creek. These two facts existed in parallel, completely disconnected from each other.

This is the structural failure the Bellingham incident exposed. The PSAP is the community's emergency hub. But the information stream from a private-sector pipeline operator's SCADA system in a remote control center runs on a completely different track. The EAP is supposed to be the bridge. When the EAP notification chain doesn't function — when the operator doesn't call — the PSAP is the last to know about an event they are simultaneously responding to from the public side.

The question for your center: if a pipeline operator in your jurisdiction detected a release right now, do you have any reason to believe they would call you before you received the first public 911 call? Do you know who they would call? Is that contact verified in the NENA PIPE database?

When Bellingham Fire's Hazmat Team was dispatched at approximately 4:34 PM, they were responding to an odor complaint — not a known gasoline pipeline rupture. The responders who arrived at Whatcom Creek at 4:45 PM encountered overwhelming fumes and gasoline flowing in the creek. A firefighter on the footbridge near the water treatment plant was near the explosion site when ignition occurred ten minutes later.

Dispatchers can only brief responders on what they know. At 4:34 PM, the known facts were: multiple callers reporting gasoline smell near Whatcom Creek, one caller reporting creek discoloration. A hazmat team was the appropriate response. What dispatchers could not tell those units was that they were walking into a situation where 277,000 gallons of gasoline had been accumulating for over an hour and the vapor cloud had reached explosive concentration.

The training point is not that dispatchers failed — it is that the EAP notification failure left dispatchers without the information they needed to give responders a meaningful safety briefing. An effective EAP would have had Olympic Pipeline calling the PSAP at 3:25 PM, giving dispatchers the information to brief units: confirmed pipeline release, product type, approximate volume, hazard zone, and operator contact on scene.

At 4:57 PM, Olympic Pipeline operators called the fire department dispatcher to report a "possible release of product into Whatcom Creek." At that moment, the dispatcher was managing an active mass casualty event — units on scene, two critically burned victims being transported, evacuation underway, Interstate 5 closed, and the creek on fire. The pipeline operator was calling to report something the PSAP had been managing, from the public side, for the past 90 minutes.

This call — arriving after the event — still has value. The operator can tell dispatchers: the product type (gasoline), the approximate volume released, where the upstream valve closure is, what the pipeline runs, and who the on-scene technical contact is. All of that is operationally useful for an ongoing hazmat response even after ignition. The dispatcher should take that call, extract the technical information, and route it immediately to the incident commander.

The lesson is not that the operator's late call was useless. It is that a timely call — at 3:25, when the SCADA alarm activated — would have meant a fundamentally different response. The 4:57 call is what you get when there's no functioning EAP notification. The 3:25 call is what the EAP is supposed to produce.

Once the fire was underway, the PSAP was managing a cascading infrastructure event. Gasoline vapor at explosive concentrations had entered the municipal sewer system — meaning any ignition source in a storm drain or manhole anywhere downstream could produce a secondary explosion. The fire was moving down a living creek toward downtown Bellingham and Bellingham Bay. The Coast Guard closed the bay. Interstate 5 was closed. The water treatment plant was severely damaged.

This is the multi-agency coordination challenge that follows a pipeline event: it is not contained to the initial rupture site. Dispatch coordination has to account for the downstream geography of the product — where is the creek going, what infrastructure is in the path, which agencies own what piece of the response, and who is running the unified command?

For training coordinators: this is the scenario design question for a tabletop exercise. Where does your nearest major pipeline run? If it ruptured into a waterway, where does that waterway go, what is downstream, and who handles what?


Section 5 — Operational Lessons

What Bellingham Changed

Lesson 1 — The EAP Notification Requirement Now Exists Because of This Incident
Current PHMSA regulations explicitly require pipeline operators to immediately and directly notify the PSAP serving the affected community when there are indications of a pipeline facility emergency. That requirement was not in effect in 1999. The Bellingham explosion is why it exists. The question for your center is whether pipeline operators in your jurisdiction are actually complying with it — and whether your center is reachable through verified contact information in the NENA PIPE database.
Lesson 2 — Caller Report Patterns Are a Pre-Incident Intelligence Signal
Multiple calls reporting an unexplained petroleum odor in a concentrated geographic area, especially near a waterway or green space, should trigger a pipeline awareness check. The NPMS Public Viewer can tell you in under two minutes whether a transmission pipeline runs through that area and who the operator is. That information changes the nature of your response from "odor investigation" to "possible pipeline event" — and changes what you tell your units before they walk into a vapor cloud.
Lesson 3 — Know What's in the Ground Before the Call Comes In
The Bellingham dispatchers had no reason to connect a gasoline smell near a public park to a major petroleum pipeline running through it, because they didn't know the pipeline was there. The NPMS exists to close that gap. A training coordinator who pulls up the NPMS for their county this week and identifies the pipelines running through their jurisdiction has already taken the most important pre-incident action this exercise can produce.
Lesson 4 — The Pipeline Safety Trust and Regulatory Legacy
The families of Wade King, Stephen Tsiorvas, and Liam Wood did not disappear into grief. They organized. The Pipeline Safety Trust — founded in the aftermath of the Bellingham explosion — became the leading national advocacy organization for pipeline safety transparency and public access to pipeline data. The NPMS Public Viewer exists in part because of their work demanding that communities know what is running beneath their feet. The data tools available to dispatchers today have a direct lineage to that creek in Whatcom Falls Park.

Section 6 — Discussion Questions

For Your Shift or Training Session

No right answers. Pull up the NPMS for your county before you start. The questions will land differently if you're looking at actual pipelines in your jurisdiction.

Discussion 1
Open the NPMS Public Viewer for your county. What pipelines are running through your jurisdiction? For each one: do you know who operates it? Do you have an emergency contact? Are you in the NENA PIPE database so they can reach you directly?
This is not a hypothetical. The answer to these questions tells you your current gap. If you don't know the answer, that's the first thing to fix before the next dispatch shift.
Discussion 2
Your center receives three calls in twenty minutes from different locations near the same waterway reporting a petroleum smell. No pipeline operator has called. What do you do, and at what point does this stop being a routine hazmat investigation and start being something else?
Consider: Is there a threshold — call volume, geographic clustering, specific descriptors like discolored water — that would change your dispatch level? Does your center have any protocol for cross-referencing odor complaints against pipeline infrastructure data?
Discussion 3
Your hazmat unit is responding to an odor investigation near a waterway. You now know from the NPMS that a hazardous liquid pipeline runs beneath that area. The operator has not called you. What do you tell the responding unit, and who do you call to get more information?
The NPMS shows you the operator name and contact information. The question is whether your dispatcher knows to look it up and make that call proactively rather than waiting for the operator to call in.
Discussion 4
The pipeline operator calls your center 90 minutes after a rupture to report a "possible release." The creek is already on fire. Your units are on scene. What do you do with that call, what information do you extract, and how do you route it?
The operator is late — but they have technical information you still need: product type, volume, valve closure status, on-scene technical contact. How does that information get from the phone call to the incident commander on scene?
Discussion 5
Gasoline has entered the municipal sewer system. The fire is moving down a creek toward downtown and the bay. You have units at the initial scene, a hospital alert going out, and three counties of mutual aid activating. How does your center manage the expanding geographic scope of a pipeline event that doesn't stay at the rupture site?
This is a supervisor-level scenario. Where is the unified command? Who owns the downstream waterway response? Who notifies the Coast Guard? Who is tracking the vapor cloud? These are answerable questions — but only if someone has thought about them before the event.

Section 7 — Knowledge Check

Five Questions

Operational judgment. Progress saved locally.

Olympic Pipeline — Knowledge Check

Select the best answer, then submit.

Question 1 of 5
Olympic Pipeline's SCADA system registered a pressure anomaly at 3:25 PM. The first public 911 calls about a gasoline smell came in at approximately 3:30 PM. The pipeline operator contacted the PSAP at 4:57 PM. What does this sequence illustrate about the EAP notification requirement?
Question 2 of 5
The NPMS Public Viewer is available to anyone with internet access. The PIMMA application provides more detailed data but requires an application for access. For a PSAP, which access tier is most operationally useful and why?
Question 3 of 5
Your center receives multiple 911 calls reporting a strong petroleum odor near a waterway. No pipeline operator has called. The NPMS shows a hazardous liquid transmission line running through that area. What is the most operationally sound next step?
Question 4 of 5
The NENA PIPE Database connects pipeline operators with PSAPs along their routes. Why does it matter whether your center is listed in this database?
Question 5 of 5
The Pipeline Safety Trust was founded by the families of the Bellingham victims. Its primary relevance to the PSAP community today is:
