Environmental Concerns

CONTAMINATED SOIL

• Contaminated soil cannot be used as fill elsewhere. It must be sampled and disposed at approved landfill (regulation allows for return to site, but the project specs do not allow this)

• Contaminated soil would be disposed as non‐hazardous waste due to LUST site exemption found in 40 CFR 261.4(b)10 [Lab and Landfill Options] o For the Wasatch Regional Landfill, a sample must be taken and waste profiled (expect 3 day turnaround for lab and profiling before disposal); landfill can provide rolloff container at cost;

estimate disposal at $40/ton o Landfill Profile: Richard McMullin 801‐253‐1111 RMcMullin@republicservices.com o Lab: American West Analytical Services 801‐263‐8686 TCLP Metals, TCLP Volatile, TCLP

Semivolatile (confirm these with McMullin)

WATER

• Contaminated Zones: Contaminated water must be sampled and disposed off-site of according to federal, state, and local regulations for the type and quantity of contaminant.

• Non-Contaminated Zones: Rising groundwater can be pumped out and either returned to the site (no permit required) when finished or discharged to the storm drain with a Utah Groundwater Discharge permit (see permit section of Specs: 01 41 26).

o Contamination Disposal option: ET Technologies o Permit: Contact DEQ, Hillary Mason 801‐536‐4162 for initial assistance https://deq.utah.gov/legacy/programs/water‐quality/ground‐water/permits/index.htm#cuicp [Option]

KNOWN CONTAMINATION ZONE

• Workers must be notified of contaminated soil and groundwater:

o Ground water only: (Vinyl Chloride) (TCE) (Cis‐1,2‐DCE) (1,1‐DCE) o Soil & GW: (Benzene) (TPH‐G) (TPH‐D)

• See maps of IRP zones

• See map of IRP wells; well integrity must be preserved for seven known wells. Nine wells are expected in the zone. Two wells have not been located (ANGMW16‐B & ANGMW16‐C). If located, notify government. Government will evaluate and determine how to proceed.

PIPE MATERIAL IN CONTAMINATION ZONE

• Drinking Water standards apply; Utah Administrative Code R309‐550‐5(10); SLC public utilities does not use PVC in contaminated soil. Ductile Iron piping is required in contaminated areas. For details on locations and requirements, see Drawings and Specifications (particularly Mustang Dwgs G-04 Notes 46-48 and C-04) mailto:RMcMullin@republicservices.com https://deq.utah.gov/legacy/programs/water-quality/ground-water/permits/index.htm#cuicp https://deq.utah.gov/legacy/programs/water-quality/utah-underground-injection-control/resources.htm https://deq.utah.gov/legacy/programs/water-quality/utah-underground-injection-control/resources.htm https://rules.utah.gov/publicat/code/r309/r309-550.htm

4. J = The analyte was positively identified: the associated numerical value is the approximate concentration of the analyte in the sample.

5. # / # = Parent Sample Concentration / Field Duplicate Concentration.

6. Bold indicates the analyte was detected.

7. Red indicates the analyte exceeded cleanup level.
