Abstract 

Hill Air Force Base has requested a modificalWn to the consolidated Approval Order (AO) for all of 

its aircraft engine test facilities. The AO covers eight test facilities (either hush houses or test stands), 

one ofwhich is grandfathered, and two of which are replacements for grandfalhered stands. This AO 

will supersede DAQE-469-94, dated June 9, 1994. This modificalWn clarifies the lOCalWn of the test 

suuuis and hush houses, and allows for the use of JP-5 jetfuel, which is required for Navy Aircraft.

Subject: Modification for Hill AFB aircraft engine test stand Approval Order (DAQE-0469-95) 

File Path: f:\aq\engineer\dbird\wo\memos\hillairc.mem 

Description 

Hill AFB submitted a request dated October 14, 1994. to modify language in their Aircraft Engine Test 

Facility consolidated Approval Order. The changes in language are necessary to clarify the location of the 

test stands, and to add JP-5 to the list of acceptable fuels. JP-5 is similar in formulation to JP-8, but with a 

higher flash point. This fuel is required by Navy aircraft that will land on aircraft carries, as a safety 

precaution. 

Emissions 

There will be no change in emissions from this modification, because emissions are restricted by the type 

and number of tests allowed. 

There was no BACT determination for this modification 

RecornrnendatioD 

The attached approval order should be sent (it contains iecllirie and strikeoUl text identifying language 

changes in conditions 5, and 10). 

There is no fee required for this modification

As the emissions are calculated with the engine type and the number oftests only, the 

emissions do not depend on the number of test facilities. Therefore, there is no increase of 

emissions. Notification will be given to you concerning the planned facilities stanup date. 

Also please change Condition 10. Fuels. As Hill AFB maintains Navy aircraft too, we 

request JP-5 to be included as a permitted fuel. JP-5 is essentially the same fuel as JP-8.but 

it has a higher flashpoint to meet shipside requirements. Emissions from the Aircraft Test 

Cells using JP-5 will be the same as using JP-8. 

If you have any questions. please call Mr. Andreas Zekom at 777-0359. 

Sincerely
