Re: Accidental Spill of Firefighting Foam at the Safety Training Center Update (District 2)
This memorandum provides an update on the previous Council Memorandum dated
Jan. 27, 2022, provided as Attachment A, relating to the events from an accidental spill of
firefighting foam during firefighting training at the Safety Training Center, or STC, on
Jan. 18, 2022.
Background
On Jan. 18, 2022, the Fire Department was conducting fire engineer training at the STC.
A mechanical malfunction on a fire engine caused a leak of approximately 15-20 gallons of
Phos-Chek 1% fluorine-free synthetic firefighting foam to discharge onto the concrete training
area, subsequently entering the underground storm drain system. The foam also left the STC
site in a diluted form, discharging into the outfall located in the adjacent canyon southeast of
the Police & Fire Headquarters facility.
Discussion
Upon completion of the initial response efforts described in Attachment A, staff began
exploring several options to perform an on-site remediation to prevent any further release of
the foam and wastewater from leaving the STC best management practices system, or BMP,
infrastructure.
On Jan. 24, 2022, staff had several discussions with the foam manufacturer and the Encina
Wastewater Authority, or EWA, on foam discharge options. On Jan. 26, 2022, staff submitted a
Non-Significant Wastewater Discharge Form, or NSWDF, requesting to discharge approximately
25,000 gallons of wastewater containing diluted foam concentrate to the sanitary sewer
system. On Jan. 27, 2022, EWA approved the NSWD,F Form #SU 2022-1, provided as
Attachment B, for discharge into the sanitary sewer system to occur on Feb. 2, 2022 to
Feb. 9, 2022.

Re: Accidental Spill of Firefighting Foam a e Safety Training Center (District 2)
This memorandum provides information relating to the events from an accidental spill of
firefighting foam during firefighting training at the Safety Training Center, or STC, that occurred
recently.
Background
On Jan. 18, 2022, the Fire Department was conducting fire engineer training at the STC. At
approximately 1 p.m., a mechanical malfunction on the fire engine caused a leak of
approximately 15-20 gallons of Phos-Chek 1% fluorine-free synthetic firefighting foam. The
concentrated liquid leaked onto the concrete training area around the commercial and
residential training props. The liquid also leaked into slot drains that connect into a
20,000-gallon underground water reclamation tank.
Due to the high pressure of water from the fire hoses, the liquid concentrate was agitated and
began to spread throughout the stormwater best management practice systems, or BMPs, at
the STC. Due to the amount of liquid concentrate and large amount of water being discharged
at the time of the mechanical malfunction, the foam also flowed underground through the
stormwater system, discharging into the outfall located in the adjacent canyon southeast of the
Police & Fire Headquarters facility.
Discussion
Actions/Response:
• Fire Engineers with support from Fleet Division personnel immediately assessed and
repaired the leak on the fire engine
• The STC Facility Manager provided immediate notification to the city's Environmental
Management Department and Risk Management Division
• Public Works staff assessed the STC site, BMP infrastructure and stormwater
infrastructure to determine how far the foam traveled off-site
• Fire Department staff notified the County of San Diego Hazardous Materials Division, or
HM_D. Upon notification, HMD assigned an incident Record ID DEH2022-HHIRT-004945
and determined that no additional response was required, and no further action was
needed

• Fire Department staff also notified the California Governor's Office of Emergency
Services, or Cal OES, and Incident #22-0360 was issued
• Environmental Management Department staff verbally notified the San Diego Regional
Water Quality Control Board, or Regional Board
• Public Works staff coordinated a site visit by US Ecology to determine potential
mitigation and remediation procedures
Since the incident resulted from a mechanical malfunction of equipment that occurred during
training, and it did not occur during emergency operations, a Cal OES spill/release notification
was required and occurred. Since unauthorized discharge entered the stormwater BMP
infrastructure, verbal notificatio-n to the Regional Board was required and occurred. Staff is in
the process of determining what sanctioned regional remediation efforts may be required, if
any, at the STC, to prevent any additional foam from leaving the STC BMP infrastructure.
Based on preliminary assessments, the incident had no negative impacts to public health and
safety or the environment. If Cal OES and/or the Regional Board require additional actions or
reporting, staff will ensure those requirements are met.
Next Steps
Staff will provide a follow-up memorandum notifying City Council of any further required
actions relating to this incident.
