Mobil Oil Guam, Inc., Cabras Terminal 

Part 71 Federal Title V Draft Operating Permit

April 2016

Background

Under the Clean Air Act (CAA), 40 CFR Part 70 Permits Program, all title V major sources of 

hazardous air pollutants are required to apply for and obtain a Part 70 title V operating permit 

from state, tribal, and local agencies. If the state, tribal, and local agencies do not have an U.S.

Environmental Protection Agency (EPA) approved Part 70 Permits Program, then EPA is 

authorized by the CAA to issue title V operating permits under the 40 CFR Part 71 Federal 

Permits Program.

The Island of Guam (Guam) is an unincorporated territory of the United States and does not 

currently have an EPA-approved Part 70 Permits Program. Therefore, EPA is authorized by the 

CAA Part 71 Federal Permits Program to issue title V permits to all title V sources located on 

Guam.

Mobil Oil Guam, Inc. (Mobil Oil Guam) owns and operates a bulk petroleum products terminal 

on Apra Harbor in Piti, Guam (the facility). The facility receives refined petroleum products, 

such as gasoline and distillate fuels, that are delivered by transoceanic tanker ships. The refined 

petroleum products are stored onsite at a tank farm before uploading the products onto tanker 

trucks for distribution to local and regional areas in Guam. The facility’s operations are subject 

to several federal regulations and Mobil Oil Guam is required to apply for and obtain a title V 

operating permit. 

In October 2010, Mobil submitted a title V operating permit application to EPA, who has 

reviewed the application and prepared a draft Part 71 title V operating permit for the Mobil Oil 

Guam facility. EPA is public noticing the draft Part 71 title V operating permit requesting 

comments from the public.
