OSHA  is trying to define the phrase "feasible administrative or engineering controls" as used in the general industry and construction occypational noise exposure standards.  The goal as usual with this “New Sheriff” brand of OSHA is to amend enforcement procedures.  According to OSHA, they interpret feasible to mean “capable of being done”.

OSHA's  standards require that noise must be reduced to acceptable levels by feasible administrative or engineering controls before protecting employees with personal protective equipment.

Under the agency's current enforcement policy, however, the agency issues citations for failure to use engineering and administrative controls only when they cost less than a hearing conservation program or such equipment is ineffective.
