It is a scam.
The government does not offer grants to individuals for personal use.
It is a scam ran by off shore con artists to trick you into sending unrecoverable money to them, you get nothing in return.
The only legitimate avenue for government grants is through www.grants.gov which is the official US government webs site for grants.
From their FAQ concerning fraud:
http://www.grants.gov/web/grants/support/general-support/grant-fraud.html
Please note the following:
No government grant-making agency will make phone calls; send email or letters to solicit money or personal banking information from a potential grant recipient.
There are no processing fees for federal grants.
Federal grants are not issued for personal use, but are intended for institutions and non-profits to carry out projects with a public purpose.
Know who you're dealing with on the web. Scam artists will often post a website with a name similar to a legitimate site.
If you have provided personal banking information to anyone claiming to be associated with a Federal grant agency, call your bank immediately to prevent unauthorized access to your account.
If you receive a call, mail, email, FAX, or any other form of communication soliciting you for a grant, STOP.
It is a scam.

Just for giggles i dialed the 206-866-5738 number. Some lady answered and sounded annoyed. Guess a lot of people have been calling her to confirm their "grant money"! She should change her number.
