5/2/96 

I. Authority to Construct - Any person building, altering or replacing any equipment, the use 

of which may cause the issuance of air contaminants or the use of which may eliminate or 

reduce or control the issuance of air contaminants, shall first obtain authorization for such 

construction from the Control Officer. An Authority to Construct shall remain in effect until 

the Permit to Operate the equipment for which the application was filed is granted, denied, 

or canceled. 

II. Permit to Operate - Before any new or modified equipment described in Subsection I. or 

any existing equipment so described may be operated, a written permit shall be obtained 

from the Control Officer. No Permit to Operate shall be granted either by the Control 

Officer or the Hearing Board for any equipment described in Subsection I., constructed or 

installed without authorization as required by Subsection I., until the information required is 

presented to the Control Officer and such equipment is altered, if necessary, and made to 

conform to standards set forth in Rule 208 (Standards for Granting Application) and 

elsewhere in these Rules and Regulations.

A. New Equipment - A person shall notify the Control Officer before operating or using 

equipment granted an Authority to Construct. Upon such notification, the Authority to 

Construct shall serve as a temporary Permit to Operate for the equipment until the 

Permit to Operate is granted or denied. The equipment shall not be operated contrary to 

conditions specified in the Authority to Construct and testing requirements shall be 

satisfied. 

B. Modified Equipment - An Authority to Construct granted to modify equipment having a 

valid Permit to Operate shall serve as a temporary Permit to Operate for the equipment 

until a new Permit to Operate is granted or denied. The modified equipment shall not be 

operated contrary to the conditions specified in the Authority to Construct and a person 

shall notify the Control Officer when construction of the modification has been 

completed. 

C. Existing Equipment - When an application for Permit to Operate is filed for existing 

equipment, the application shall serve as a temporary Permit to Operate for the 

equipment. If the equipment was previously operated under a Permit to Operate and has 

not been altered, it shall not be operated under a temporary Permit to Operate contrary 

to the conditions specified in the previous Permit to Operate. 

III. Posting of Permit to Operate - A person who has been granted under Subsection II. a 

Permit to Operate any equipment described in Subsection II., shall firmly affix such Permit 

to Operate, an approved facsimile, or other approved identification bearing the permit 

number upon the article, machine, equipment, or other contrivance, in such a manner as to 

be clearly visible and accessible. In the event the equipment is so constructed or operated 

that the Permit to Operate cannot be so placed, the Permit to Operate shall be mounted so as 

to be clearly visible in an accessible place within 25 feet of the equipment or maintained 

readily available at all times on the operating premises. 

VI. Altering of Permit - A person shall not willfully deface, alter, forge, counterfeit, or falsify 

a Permit to Operate any equipment.
