I wrote them recently...and got this back:

"Thank you for contacting TD Ameritrade. EPGL has a "DTC Chill" designation on it.
When an issue is designated as "DTC chill" at Depository Trust Company (DTCC), it is not eligible for physical deposit or delivery through the DTC. These restrictions prohibit a clearing firm¿s ability to settle trades once their book entry holdings are depleted. Based on the industry wide "DTC Chill" restriction, this prohibits a clearing firms', specifically TD Ameritrade¿s, ability to settle trades and prevents book entry deliveries. If we are unable to settle our clients¿ trades, the liability of the trade becomes TD Ameritrade¿s. At this time, there is not a set timeline for if/when the restriction will be removed. However, once the industry wide "DTC Chill" restriction is lifted, TD Ameritrade will re-evaluate whether the issue will be allowed to be traded again. At this point, the only recourse you have is to contact the investor relations department of the issuer.
Other brokers may be allowing opening transactions on EPGL, however, at this time, TD Ameritrade has made the business decision to not allow opening transactions. We do not want to take the increased risk of not being able to settle trades.
I will have my Risk Department look at this security again, but I cannot give a time frame of when or if the restriction will be lifted on EPGL."

Apparently you can sell EPGL on TDA but still not buy shares...
