New Silica Rule?
example, Table 1 specifies that
when a large-drivable milling
machine (half-lane and larger)
is used for cuts of any depth on
asphalt, the employer must use "a
machine equipped with exhaust
ventilation on drum enclosure
and supplemental water sprays
designed to suppress dust... [and]
Operate and maintain machine
to minimize dust." If an employer
follows the requirements listed,
they will not have to implement
the air monitoring requirements
and, if no respirator requirement
is listed, they will not have to
comply with the standard's medical
surveillance and respiratory
protection requirements. The
"NAPA-CPWR Field Guide for
Controlling Silica Dust Exposure
on Asphalt Pavement Milling
Machines" includes a dust control
checklist, and tips for small and
large drivable milling machines
that can help employers comply
with Table 1. The Field Guide is
available for free through the NAPA
Online Store at http://goaspha.

Alternate Exposure
Assessment Methods: If a type
of equipment or task is not listed
on Table 1, or an employer chooses
not to follow Table 1, exposure
to workers must be assessed.
Employers can choose to perform
an exposure assessment using any
combination of objective data or
air monitoring data to determine
exposure levels and demonstrate
the effectiveness of the controls.
According to OSHA, objective
data can include "air monitoring
data from industry-wide surveys or

calculations" for employee exposures
"associated with a particular product
or material or a specific process, task
or activity." The objective data must
"reflect workplace conditions closely
resembling or with a higher exposure
potential" than the current operation.
If air monitoring is used and shows
that exposures fall below the action
level (AL) of 25 micrograms per
cubic meter, then no additional air
monitoring is required for the task.
However, if the air monitoring results
are above the AL then monitoring
must be repeated every six months.
If the results are above the PEL,
then monitoring must be repeated
within three months. According
to OSHA, "when two consecutive
non-initial results, taken seven
or more days apart, are below the
AL," the employer can discontinue
monitoring. Because OSHA did not
identify specific control technologies
to be used during road brooming or
sweeping activities, NAPA is working
with its members and CPWR to
identify the exposure potential
during these operations, and the
effectiveness and practicality of
using water-spray control systems to
minimize dust exposures.

Respiratory Protection
The standard's respiratory protection
requirements kick in if respiratory
protection is specified in Table 1, or
if air monitoring or objective data
shows that employees are exposed
above the PEL despite full and proper
implementation of engineering and
work practice controls. The employer's
respiratory protection program must
comply with 29 CFR 1910.134.
