How to File a Complaint About a Certified Business

As the sole certification agency for the state of Oregon, the OMWESB office processes all complaints regarding a business's certification.

If you believe that a certified business does not meet one or more certification requirements, a complaint may be filed. OMWESB investigates all complaints according to the Code of Federal Regulations, Oregon Revised Statutes and Oregon Administrative Rules. As outlined in the law, a complaint must:

  • be in writing,
  • state facts indicating which eligibility requirement(s) the business has not met,
  • include copies of any supporting documentation complainant may have,
  • be signed by the complainant and
  • include complainant's address and telephone number.


Once OMWESB receives a complaint and supporting documentation, staff review the information to determine if it warrants an investigation. If there is not sufficient cause to demonstrate that an investigation is needed, OMWESB notifies the complainant in writing that the matter is closed. If it is determined that an investigation is needed, OMWESB notifies the business named in the complaint by certified mail. All parties must cooperate fully in the investigative process.

Upon completion of the investigation, OMWESB issues a written decision to the business and the complainant. The decision will either include a finding of "no grounds for decertification" or a "notice of intent to decertify."

OMWESB will only consider complaints based on first-hand knowledge and those who provide evidence supporting the assertion.
