For the purpose of enforcing compliance with these standards, the proposal states that “feasible” has its ordinary meaning of capable of being done.

OSHA’s noise standards specify that feasible administrative or engineering controls must be used to reduce noise to acceptable levels and that personal protective equipment (PPE), such as ear plugs and ear muffs, must be used only as supplements when administrative or engineering controls are not completely effective. The preference for engineering and administrative controls over PPE is consistent with the approach taken in all of OSHA’s health standards and reflects the fact that such controls generally are more effective. 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.

OSHA is proposing to interpret the term “feasible” in conformity with its ordinary meaning and with the safety and health purposes of the OSH Act. The Supreme Court has held that the term “feasible” as used in the standard-setting provision of the Occupational Safety and Health Act means “capable of being done.” The proposal aligns the interpretation of the noise standard with the court’s holding and with OSHA’s other standards that require feasible engineering controls. The agency intends to change its noise enforcement policy to authorize issuing citations requiring the use of administrative and engineering controls when feasible as indicated in the interpretation described in the FR notice.

Every year, approximately 30 million workers are exposed to hazardous noise that is often ignored because the harmful effects of overexposure are typically not visible and develop over an extended period of time. Workers exposed to high noise levels can develop elevated blood pressure, ringing in the ears or permanent hearing loss.
