NYU Commitments to Minimize or Avoid Significant Adverse Impacts
Air Emissions Reduction Program
• Diesel Equipment Reduction (e.g., early electrification)
• Clean Fuel (ultra-low-sulfur diesel [ULSD])
• Best Available Tailpipe Reduction Technologies
• Utilization of Newer Equipment
• Source Location (placement of equipment away from sensitive receptors)
• Dust Control
• Idle Restriction
![Page 6: NYU CORE Construction Presentation · 2020-06-26 · CB2 Presentation, January 18, 2012 – NYU Core Construction Presentation 2 Construction Impacts – Chapter 20 of the DEIS •](https://reader033.vdocuments.mx/reader033/viewer/2022050208/5f5b1e417dc85d320a7ffbe7/html5/thumbnails/6.jpg)
6 CB2 Presentation, January 18, 2012 – NYU Core Construction Presentation
NYU Commitments to Minimize or Avoid Significant Adverse Impacts Noise Reduction Measures
Source Controls (i.e., reducing noise levels at the source)
• Construction procedures and equipment that produce noise levels below the requirements
of the New York City Noise Control Code
• Early electrification for certain noisy equipment (e.g., concrete vibrators, hoists, man lifts)
• Construction sites would be configured to minimize truck back-up alarm noise
• Trucks would not be allowed to idle more than three minutes
• Limit equipment on-site (only necessary equipment on-site)
Path Controls (e.g., placement of equipment, implementation of barriers or enclosures)
• Noisy equipment shielded and located away from sensitive receptor locations.
• Path noise control measures (i.e., portable noise barriers, panels, enclosures, and acoustical
tents) for certain dominant noise equipment
• Acoustical curtains for internal construction activities in the buildings under construction

7 CB2 Presentation, January 18, 2012 – NYU Core Construction Presentation
NYU Commitments to Minimize or Avoid Significant Adverse Impacts
Construction Protection Plan (CPP)
• University Village has been determined S/NR-eligible and is designated NYC Landmark
• Washington Square Village has been determined S/NR-eligible
• CPP would be developed in consultation with LPC to avoid any construction-related impacts on these architectural resources, including
ground-borne vibration and damage from heavy machinery
![Page 8: NYU CORE Construction Presentation · 2020-06-26 · CB2 Presentation, January 18, 2012 – NYU Core Construction Presentation 2 Construction Impacts – Chapter 20 of the DEIS •](https://reader033.vdocuments.mx/reader033/viewer/2022050208/5f5b1e417dc85d320a7ffbe7/html5/thumbnails/8.jpg)
8 CB2 Presentation, January 18, 2012 – NYU Core Construction Presentation
NYU Commitments to Minimize or Avoid Significant Adverse Impacts
Remedial Action Plan (RAP) and Construction Health and Safety Plan (CHASP)
• RAP would address requirements for items such as:
• soil stockpiling, soil disposal and transportation
• dust control
• quality assurance
• contingency measures should petroleum storage tanks or contamination be unexpectedly encountered
• CHASP would address the following items:
• identify potential hazards that may be encountered during construction
• specify appropriate health and safety measures to be undertaken to ensure that subsurface disturbance is performed in a manner protective of workers, the community, and the environment (including a Community Air Monitoring Program)
![Page 9: NYU CORE Construction Presentation · 2020-06-26 · CB2 Presentation, January 18, 2012 – NYU Core Construction Presentation 2 Construction Impacts – Chapter 20 of the DEIS •](https://reader033.vdocuments.mx/reader033/viewer/2022050208/5f5b1e417dc85d320a7ffbe7/html5/thumbnails/9.jpg)
9 CB2 Presentation, January 18, 2012 – NYU Core Construction Presentation
NYU Commitments to Minimize or Avoid Significant Adverse Impacts
Rodent Control
• Before start of construction, contractor would survey and bait the appropriate areas and provide for proper site sanitation
• During construction phase, as necessary, contractor would carry out a maintenance program
• Coordination would be maintained with appropriate public agencies
• Only EPA and NYSDEC registered rodenticides would be permitted
• Contractor would be required to perform rodent control programs in a manner that avoids hazards to persons, domestic animals, and non-target wildlife
