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. LOCHNER 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.
