Re: 5600 West Railroad Crossing Project and Pioneer Landfill (UTD980952816)
Dear Mr. Doug Taylor
As you are aware, the Utah Department of Transportation (UDOT) is planning roadway
improvements along SR-172 (5600 West)—approximately 3.4 miles long between SR-201 and
Interstate-80 at mileposts (MP) 5.8 and MP 9.2. The project is located in Salt Lake City, within
Salt Lake County, Utah.
Proposed improvements include widening 5600 West from a two lane section to five lanes.
There would be two lanes in each direction with a center turn lane. In addition, the project would
construct a bridge over the Union Pacific Railroad (UPRR) tracks at MP 7.8 where three existing
tracks and one additional future track that UP has planned are located. Improvements also
include addition of curb and gutter, sidewalk on both sides of the roadway, replacement or
modification of existing box culverts, reconfiguration of all intersections and traffic signal
phasing, modification of utility and storm drain systems (as needed), and reconfiguration of
adjacent side streets (where necessary).
Design is in the preliminary stages, and actual impacts from the proposed project are not yet
known. However, as a result of coordination with Utah Department of Environmental Quality
(DEQ) Division of Waste Management and Radiation Control, Utah Division of Environmental
Response and Remediation (DERR), Salt Lake County Engineering division, Salt Lake City
Public Utilities (Water Quality); the following considerations and assumptions will apply to any
potential impacts to the Pioneer Landfill:
1) Design Considerations:
• Any material moved/excavated to facilitate road construction, would be placed within the
existing footprint of the landfill and the cap reconstructed to the existing conditions,
which is a minimum of two feet.
• If excavated material is moved offsite, it needs to be placed in a permanent landfill.
• If construction of a detention pond or storm drain occurs within the footprint of the
landfill; the same rules would apply regarding excavation and placement of materials to
facilitate construction of the drain or pond.
Recommendations:
• Excavate to full depth (Do not put roadway over waste, full depth excavation of waste
should occur)
• Place barrier between excavation and roadway fill
• Continue coordination with DERR and DEQ regarding specifics of drainage
infrastructure
LOCHNER
2) Construction Considerations:
• Reclaim disturbed areas using native soils to try to match existing material for the landfill
cap.
• It is not necessary to meet the existing standards for a landfill cap because this landfill
predates new requirements.
o As long as all materials remain on existing site or waste is brought to a
permanent landfill; the site remains exempt from new standards.
• DERR would not require a DEQ employee to monitor or to visit the site.
• Division of Waste Management does not require temporary monitoring or reports during
construction.
Recommendations:
• Construction workers excavating landfill material should have the 40 Hour Hazardous
Waste Operations and Emergency Response (HAZWOPER) training or equivalent.
• UDOT should coordinate with DERR and/or EPA, the construction contractor, and the
appropriate property owners during the final design phase of the project.
• Develop a contingency plan in coordination with the DEQ to address circumstances
under which DEQ should be contacted to sample hazardous waste materials (other than
trash), and outline the appropriate protocol and steps to be followed for appropriate
disposal of hazardous materials.
3) Permit Requirements
No permits are required from the Division of Waste Management, DERR, Salt L.ake City, or Salt
Lake County for impacts to the landfill or monitoring wells.
Design team will submit work plan to Division of Waste Management including:
• Narrative description of project (short summary of project and anticipated design as
follows:
o Attached figures, details of project limits, impact areas, proposed roadway
typical/pond typical with impact limits to landfill.
o Quantity of waste removed from the site, waste placed on the site, and proposed
soils (sub-base, cap, etc.)
o Pre- and post- cross-sections
o Project plan/site map
o Information regarding construction timeframe
In addition to the above considerations and recommendations, guidance rom Part 3 "Execution"
of the UDOT Standard Specifications will apply as follows:
LOCHNER
3.1 Hazardous Waste
A. Suspend work immediately in an area if abnormal conditions are encountered or
exposed during construction that indicates the presence of a hazardous waste.
1. Notify the engineer
B. Do the following if a waste is discovered or spilled on site is considered hazardous by
meeting the definition for disclosure as defined in Title 40 CFR Part 261, Subpart D —
Lists of Hazardous Wastes.
1. Take appropriate actions to minimize the threat to human health and the
environment.
2. Contact the Engineer and send notice if waste found on site is determined
hazardous.
3. Follow appropriate testing measures to determine if waste is considered
hazardous.
4. Notify DEQ, 24-hour Answering Service, (801) 536-4123.
5. Follow requirements in UAC R315.
C. Coordinate with the Engineer to initiate development of a remediation plan according to
DEQ and the EPA regulations and requirements.
1. Pay for costs to address hazardous waste discovery or spill clean-up
when caused by Contractor's activities.
D. Complete the work required by the remediation plan before resuming operations in the
affected area.
3.2 Spill of Petroleum-Based Product and Used Oil
A. Petroleum-Based product
1. Contact the Engineer if a spill occurs adjacent to waterbody or storm drain
inlet.
a. Send notice following the discovery of the spill
b. Notify DEQ, 24-hour Answering Service, (801) 536-4123.
c. Coordinate with the Engineer to remedy petroleum contaminated
soils according to UAC R305-8.
B. Used Oil Product
1. Contact the Engineer if a spill occurs that exceeds 25 gallons, or that poses
a potential threat to human health or the environment, such as discharging
to groundwater, surface water or storm drain inlet.
a. Send notice following the discovery of the spill.
b. Notify DEQ, 24-hour Answering Service, (801) 536-4123.
c. Coordinate with the Engineer to develop a remediation plan for
spilled used oil according to UAC R315-15.

C. Clean up petroleum-based or used oil product when caused by Contractor's activities.
Please review the above considerations and assumptions and provide input regarding any
missing or incorrect items. Your input would be appreciated by June 29, 2018, after which these
assumptions and considerations will be considered correct and will be incorporated in to project
design and construction documentation.
