An unidentified NTIA source said the agency returned $241.6 million to the Treasury Department; $2.6 million went to "final closeout costs". After the program ended, $250 million from the original bill had not been used, and the additional $490 million allocated in February 2009 had not been touched. These funds almost equalled the $490 million Congress had appropriated to boost the program in January 2008, when it appeared the program would run out of money. The additional funding was needed to satisfy the accounting rules imposed on the program by Congress, rather than an actual need for the funds. The unused funds from the original bill went to a DTV public safety fund, as required in the legislation.
