VCP/Brownfields Section - Site Visit Report

SITE NAME: Airport West / North Temple Landfill

SITE LOCATION: Salt Lake City

DATE OF SITE VISIT: 28 February 2025

PURPOSE OF SITE VISIT: DERR (David Bird) oversight of field activities at the Airport West VCP site.

FIELD OBSERVATIONS: At ~ 9:00 am, the DERR met UIPA’s contractor, Ninigret (Eric Rice), and concrete
crushing subcontractor, Staker Parsons at the site to discuss how the inspection for possible asbestos
containing material (ACM), and processing of concrete into roadbase material is progressing. The pile of
processed material on site has grown. NT Development indicated that the processed concrete pile now
represents approximately 100,000 tons of roadbase, and that no more ACM had been found through the
inspection process. The crushing plant was not operating today because maintenance was underway.
I was told the crushing of concrete is about 50% done. The expected time for completion of the
crushing is the end of April 2025.
Ninigret and DERR discussed upcoming events needed to prepare for the excavation of material from
the waste cells of the landfill. This is expected to commence near the first of May 2025. Near the end
of next week, Ninigret expects to install the liner for each of the leachate ponds
The DERR left the site at ~10:00 am.

SPLIT SAMPLES COLLECTED: No
