SECTION
15: Environmental Issues
Control of Fugitive Emissions (top)
Fugitive emissions include, but are not limited to, nuisance dusts,
chemical odors, hazardous materials (such as asbestos or lead dust)
and noise. All necessary precautions should be taken to control or
contain fugitive emissions from the job site, particularly when University
employees and students occupy areas adjacent to the site.
 1. Prior to work with odorous chemicals in or near areas occupied
by University personnel, the Project Manager should send copies
of the MSDSs for such chemicals to EHS and inform the building
occupants of the scope
and timing of the work.
2. Consider manipulating the building ventilation system to minimize
fugitive emissions. This may include sealing off return air ducts
in the work area, shutting down portions of the ventilation system,
using ventilating fans or
otherwise sealing the work area from the occupied area. Thermal comfort
of
building occupants must also be considered.
3. The Contractor is required to ensure that no
University employee, student or visitor is exposed at or above
the OSHA permissible exposure
level for any chemical.
4. Whenever possible, work that will unavoidably release fugitive
emissions into occupied areas should not be conducted during regular
university business hours.
Where work practices will create high levels of noise, the Project
Manager must ensure that noise levels in occupied areas do not exceed
75 decibels.
Hazardous Waste (top)
All contractors must take precautions to ensure hazardous chemicals
or materials are disposed of in
accordance with federal and state regulations. Materials which may not be disposed
of in regular trash include,
but are not limited to, used solvents or oils, building materials which may
contain asbestos, lead paint chips,
sand-blasting grit which may contain lead paint, and unwanted paints and stains.
Contractors are responsible for removing hazardous wastes from the
work site and disposing of them
properly. No hazardous wastes may be left on campus without approval by EHS.
Chemical Releases into the Environment (top)
The Princeton University Floor Drain policy prohibits the storage
of any materials that, if spilled, would cause
groundwater contamination, in rooms which have floor drains connected to the
storm sewer system.
Examples of materials that fall into this category include: ethylene
glycol, oil, cleaning fluids, fuel, solvents,
biocides, herbicides, etc. In addition, drains not connected to the sanitary
sewer system cannot be used to
drain away floor cleaning materials or compressor blowdown, and the drains
must be sealed off when work is
done in these rooms that involves a material that could contaminate the
surface water. Project managers shall
inform the contractors of these requirements whenever work is to take
place in these rooms.
If an accidental release of a chemical to the environment occurs,
the contractor must notify Public
Safety immediately at 911. Public Safety will contact the Facilities
Manager of Environmental Compliance or EHS.
A release to the environment
may include a spill directly into water (including
groundwater) or a spill directly
onto land.
Planned releases of tracer dyes into the storm sewer system for the
purposes of testing roof or other
membranes, tracing pipe systems, etc. must be reported to Public Safety at
8-3134 or EHS at 8-5294 at least
24 hours in advance. An MSDS of the dye to be released should be faxed to EHS
at 8-1804.
