RE: Mayor’s Office of Emergency Management 7 World Trade Center S5Zi51I5_

Dear Mr. Weems;

The generator load test was conducted on Saturday July 31. 1999

Tt]e following items were found to have minor problems and will be corrected as per the following; I

The differential pressure controller will be re-programmed on August 4,1999 This will cli^se the building valves and start emergency condenser water system manually as designed. Riissel Electric, the manufacturer of the ATS switches, is aware of the problem with them. Their engineering personal is working on the minor glitch, and as soon as they have r®'’ched a solution the corrective work will be done. They have said it is just a matter of adding some relays. Once this is accomplished, we can then run the loaid Shedding test. I

111 Cosentini Associates report (attached) the emergency generator were left in the automatic position and is ready to deliver emergency power on demand, therefore the OEM is ready for power emergency. I If you have any questions regarding this matter please contact us.

very truly yours,

/^^SSADOR O6NSTRUCTION CO., INC.
