Additionally, any emissions activities determined from your Air Quality PermitApplication as being insignificantper 15A North CarolinaAdministrativeCode2Q.0503 havebeen listed for informational purposes as an "ATTACHMENT." Please note the requirements for the annual compliance certification arecontained in General ConditionPin Section 3. Thecurrentowneris responsiblefor submitting a compliance certification for the entire year regardless ofwho owned the facility during the year.

As thedesignated responsible official itis yourresponsibility to review, understand, and abide by all of the terms and conditions of the attached permit. It 

### is also your responsibility to ensure that any person who operates any emission source and associated airpollution control device subject to any term orcondition ofthe attached permitreviews, understands, and abides by the condition(s) ofthe attached permit that are applicable to that particular emission source.

If

### anyparts, requirements, orlimitations contained in this Air Quality Permit are unacceptable to you, you have the right to request a formal adjudicatory hearing within 30 days following receipt of this permit, identifying the specific issues to be contested. This hearing request must be in the form of a written petition, conforming to NCGS (North Carolina General Statutes) lSOB-23, and filed with both the Office of Administrative Hearings, 6714 Mail ServiceCenter, Raleigh, North Carolina 27699-6714 and the Division of Air Quality, Permitting Section, 1641 Mail Service Center, Raleigh, North Carolina 27699-1641.
