Summarize Corrective Action:
Consultant performing visual monitoring assessment inspected the contributing areas leading to Outfalls
15 and 16. The white particles were traced back to a large section of new concrete located immediately
south of the Southwest Maintenance Hangar and wash bay. Consultant observed identical white particles
in the concrete cracks, along the curb, and in a storm drain inlet. Particles appeared to be wide-spread
and apparently not attributable to a single point source.
Consultants made contact with a Southwest employee. The employee stated that the particles are from a
sealant that was applied to the concrete approximately one year ago and that it flakes up occasionally.
The employee organized a street sweeper to clean the pavement and curbing. Consultant notified City of
Phoenix Aviation personnel and the Southwest Pollution Prevention Team Member of the issue and
follow up activities.
Southwest will increase street sweeping in the area, especially before rain events. City of Phoenix
Aviation personnel will visit the area later in the day to confirm adequate street sweeping was performed.
This area will be revisited during the January Comprehensive Facility Inspection.
No changes to the SWPPP are planned in response to this incident.
