Go to any lumber company's web site and marvel at 100,000 bdft of lumber stacked for air drying. Do what they do.
Your concern needs to be mold. White pine is the most prone to mold wood I know of besides Holy. You picked a terrible time of year to receive delivery. Warm enough to grow mold, cool enough to dry too slow. Get air to this lumber quickly....lots of moving air.
Pick a place with excellent air circulation-CRITICAL. Make a level base, well off the ground, with support at least every 4'. 12" block works well. I would risk 4' spacing for this thick stuff to be cut into short lengths. Given the wide widths pick a stack width to work out efficient- 36 to 48". Lay down a layer, not touching edges. Lay down at least 3/4 and 1" better DRY sticks 2' spacing. Continue and make sure sticks line up one exactly above the other. When you reach the top add a layer of junk that you got from the mill. Maybe you can use some of it later for some application. The add a water impermeable cover several inches above the pile (raise it on 4 x 4 for example. I use roofing tin. Slope it so the water runs off the end. Overlap on all sides so run off from top does not run down the sides of the pile. MOST critical, do not allow water to trickle through this roof into the pile.
Your challenge is mold prevention. Had this pine been delivered here in TN it would mold in 48 hours this time of year.
423- 357-4850 if you wish. Years and thousands of bdft experience.
Pine dries quick, but it has gobs of water to release. It is the heaviest wood green and feather light dry. You will grunt on the 8/4 wide stuff.
