FactSheet

Filing Whistleblower Complaints under the 

Clean Air Act

Employees are protected from retaliation for reporting alleged violations regarding 

air emissions from area, stationary, and mobile sources. 

Covered Employees

The Clean Air Act (CAA) prohibits employers 

from retaliating against employees for engaging 

in protected activities pertaining to alleged 

violations of air emissions from area, stationary, 

and mobile sources that affect public health and 

the environment.

Coverage extends to all private-sector, federal, state 

and municipal employees in the United States.

Protected Activity

A person may not discharge or in any manner 

retaliate against an employee because the 

employee: 

• Provided (or is about to provide) information 

relating to a violation of the CAA to the 

Environmental Protection Agency (EPA) or other 

appropriate Federal agency or department; 

• Testified or was about to testify in any such 

proceeding under this statute;

• Refused to perform duties in good faith, 

based on a reasonable belief that the working 

conditions are unsafe and unhealthful;

• Participated or assisted in a proceeding under 

this statute.

Unfavorable Employment Actions

A person may be found to have violated CAA 

if the employee’s protected activity was a 

motivating factor in the person’s decision to 

take unfavorable employment action against the 

employee. Such actions may include:

• Firing or laying off

• Blacklisting

• Demoting

• Denying overtime or promotion

• Disciplining

• Denying benefits

• Failure to hire or rehire

• Intimidation

• Making threats

• Reassignment affecting prospects for 

promotion

• Reducing pay or hours

Deadline for Filing Complaints 

Complaints must be filed within 30 days after the 

alleged unfavorable employment action occurs 

(that is, when the employee is notified of the 

retaliatory action). 

How to File a CAA Complaint 

An employee, or representative of an employee, 

who believes he or she has been retaliated 

against in violation of CAA, may file a complaint 

with OSHA. Complaints may be filed verbally 

with OSHA by visiting or calling the local OSHA 

office at 1-800-321-OSHA (6742), or may be filed 

in writing by sending a written complaint to the 

closest OSHA regional or area office, or by filing 

a complaint online at www.whistleblowers.gov/

complaint_page.html.

Written complaints may be filed by facsimile, 

electronic communication, hand delivery during 

normal business hours, U.S. mail (confirmation 

services recommended), or other third-party 

commercial carrier. 

The date of the postmark, facsimile, electronic 

communication, telephone call, hand delivery, 

delivery to a third-party commercial carrier, or 

in-person filing at an OSHA office is considered 

the date filed. No particular form is required and 

complaints may be submitted in any language. 

To file a complaint electronically, please visit 

www.whistleblowers.gov/complaint_page.html.
To contact OSHA to file a complaint, please call 

1-800-321-OSHA (6742) and they will connect 

you to the closest office; or visit www.osha.gov/

html/RAmap.html. 

Upon receipt, OSHA will review the complaint to 

determine whether it is appropriate to conduct 

a fact-finding investigation (e.g., whether the 

complaint was filed within 30 days; whether the 

allegation is covered by CAA). All complaints are 

investigated according to statutory requirements 

in 29 CFR Part 24.

Results of the Investigation

If the evidence supports an employee’s claim 

of retaliation and a voluntary settlement cannot 

be reached, OSHA will seek relief to make the 

employee whole, including:

• Payment of back pay with interest.

• Compensation for special damages, to 

include attorney’s fees, and other expenses 

the employee may have incurred as a result 

of the violation.

• Reinstatement.

OSHA’s findings and order become the final 

order of the Secretary of Labor unless either 

party objects to the findings within 30 days. 

After OSHA issues its findings and order, 

either party may request a full hearing before a 

Department of Labor Administrative Law Judge 

(ALJ). The ALJ’s decision and order may be 

appealed to the Department’s Administrative 

Review Board.
