The Site Supervisor shall ensure that:
# All equipment and vehicles are be chocked and nmintair ed daily to prevent leaks
of hazardous materials.
= Spill kits and spill containment materials are available on -site at all times and that
the equipment is in good working order.
Equipment required to contain and clean up a frao-out release will either be
available at the work site or readily available at an offsite location within 15-
minutes of the bore site,
If equipment is required to be operated near a riverbed, absorbent pads and
plastic sheeting for placement beneath motorized equipment shall be used to
protect the riverbed from engine fluids.
