My local casino pays 3:2 on bj but only allows aces to be split one time. A new rule has been introduced where we have the option to either stand or surrender when we split our aces.

For example if the dealers up card is a 10, we split our aces, and receive a 5 and a 2 giving us two hands: soft 16 and soft 13. Should we stand or surrender?

If possible, can someone write out the best plays for each soft hand in this scenario?

You would simply play basic strategy under the surrender rules.
surrender 16 hit 13

They don"t let you hit your split Ace'S I presume.

I'm assuming this is a shoe game. I'm also assuming that you either have to stand on both split hands or surrender both.

Surrender vs 8-10 if both hands are less than 17.

For H17, surrender vs A if both hands are 17 or less.

For S17, surrender vs A if either both hands are less than 17 or one hand is 17 and the other is less than 17.

There is an 8-deck shoe and continuous shuffler. Take your pick.

You must stand or surrender after you get your first card to go with your ace. You can surrender one hand and stand the other. Let me know if there are any other questions.

With that said, can someone provide the proper play for each hand and what effects this will have on the house edge?

You can figure out the proper play by looking at this:

It might be tedious but it is more fulfilling! For every soft hand you have, look at the EV from standing (which is your only other option), if it is less than -0.5, the EV of surrendering, then surrender.
Notice that every hand that is 16 or less, the EV is almost the same, as you only win if the dealer busts, and it will depend on the dealer's upcard, so that'll make it quicker to deduce what ChesterDog posted.

It's good that you may decide whether to stand or surrender the split ace hands separately.

If the game is H17 (dealer must hit all his soft 17s), you should only surrender a split ace hand if its total is 12-16 vs dealer's 8, 9, or 10 or its total is 12-17 vs dealer's A.

If the game is S17 (dealer must stand on all his soft 17s), you should only surrender a split ace hand if its total is 12-16 vs dealer's 8, 9, 10, or A.

I find this player-favorable rule decreases the house edge of the H17 game by 0.0096%. For the S17 game, the edge is decreased by 0.0112%.

(For example, the Wizard's Blackjack Edge Calculator gives an edge of 0.55526% for an 8-deck H17 continuous shuffle game allowing late surrender and split non-ace pairs to four hands. Adding your surrender-split-ace rule would decrease this to 0.54569%.)

surrender any stiff hand (16 or below) and stay any 17 or above

I'm assuming that will be the play against a dealer 8,9,10 and A. How will this effect the house edge?

I am also assuming that I will stay 12-16 against a dealer 2-7. Please confirm.

No, because the EV of standing on those is greater than -0.5 (surrender if the best play you could otherwise make is less than that).
