Four Corners Environmental, Inc. Project No. 12087
Dear Ms. Riemenschneider:
Pursuant to your request, Four Corners Environmental, Inc. (Four Corners) is pleased to provide the
enclosed final letter of emergency response and sampling activities for the Salt River Biodiesel Release at
Sky Harbor International Airport in Phoenix, Arizona. Project activities have been completed in
accordance with Four Corners’ Proposal Number P-12-087, dated September 24, 2012.
PROJECT BACKGROUND
A City of Phoenix grader broke a fuel valve during grading work on a roadway along the southern portion
of the Salt River on September 24, 2012. The biodiesel release impacted an approximately 0.3 mile long
portion of a dirt roadway on the southern bank of the Salt River channel. Approximately 74 gallons of
biodiesel fuel was reportedly released to the dirt.
The City of Phoenix contracted Four Corners to provide characterization of impacted and stockpiled soil
for disposal, conduct soil remediation oversight, and confirmation sampling activities after completion of
the excavation. In accordance with regulations and our understanding of the disposal site requirements,
the soil was tested for contaminants including volatile organic compounds (VOCs), Total Resource
Conservation and Recovery Act (RCRA) 8 Metals, polynuclear aromatic hydrocarbons (PAHs), and total
petroleum hydrocarbons (TPHs). Confirmation soil sampling was tested for contaminants including VOCs
and PAHs, only.
