It was .03 at suprnova and was changed without notice recently.

Also, be advised that suprnova rounds etn to the lowest whole number on payout so if you have a payout of 104.2, minus .3 transaction fee it should be 103.9, right?  Wrong.  When they send the transaction, it's only 103 so you are losing .9 etn.  That .9 etn is not credited to your existing balance...It's gone.

Other pools cover the tx fees since they are are all bundled in one transaction and send whole numbers and leave the remaining as a balance in your account.  So if I have 88.29 balance, when the payment processor runs, you get 88 and have .29 remaining in your account.  Hashvault pays out at .1 so if you have a balance of 88.29, they pay 88.2 and you have .09 left in your account.

I've had to stop using suprnova etn until this accounting error has been corrected.  If you have payouts set to their minimum of 10, you'll be losing a lot of etn over time.  I've lost 1.64 in just 4 payouts so far.
