I have a question about the relevancy of the OSHA PEL where  VOCs such
as PCE or TCE are detected in indoor commercial space at levels below
OSHA PELs. Does anyone know if the OSHA PEL can be used as an ARAR? I am
concerned that the OSHA PELs are numbers derived from the 1970s so that
they do not reflect the latest science, and obviously time-weighted over
an 8 hour period. I have found some consultants using the OSHA PEL as a
remediation standard and am somewhat dubious that the OSHA PEL can be an
appropriate standard to use when determining if indoor air
concentrations are at levels that require remediation or at least
disclosure to workers.
