PART 1.0 FACILITY DESCRIPTION

1.1 Site Determination

Delta Air Lines, Inc. campus at the Hartsfield-Jackson Atlanta International Airport is composed of 

two Title I sites and one Title V site consisting of three Title V permitted facilities. The two Title I 

sites are (1) the eight emergency generators associated with the Worldspan reservation operation and 

(2) all other Delta activities on/adjacent to the Delta campus. Three separate Title V permits have 

been issued to Delta to consolidate the activities of the three distinct operations: (1) General Office 

Facilities, which are the corporate headquarters and related administrative and service support 

operations; (2) Technical Operations Center, which conducts the aircraft maintenance and other 

facilities maintenance activities; and (3) Atlanta Station, which conducts the day-to-day operations 

and maintenance for Delta’s assets at Hartsfield-Jackson International Airport. This Title V Permit 

covers only the Delta Air Lines, Inc. – Technical Operations Center. The Hartsfield-Jackson Atlanta 

International Airport, in general, is owned by the City of Atlanta and Delta is one of several 

companies that operate there.

8.13 Excess Emissions Due to an Emergency

8.13.1 An “emergency” means any situation arising from sudden and reasonably unforeseeable 

events beyond the control of the source, including acts of God, which situation requires 

immediate corrective action to restore normal operation, and that causes the source to 

exceed a technology-based emission limitation under the Permit, due to unavoidable 

increases in emissions attributable to the emergency. An emergency shall not include 

noncompliance to the extent caused by improperly designed equipment, lack of 

preventative maintenance, careless or improper operation, or operator error.

actions taken.

8.13.3 In an enforcement proceeding, the Permittee seeking to establish the occurrence of an 

emergency shall have the burden of proof.
