Yes, pumps and compressors both shared the same Cummins drivers and he had to cannibalize the compressors to replace the motors on the pumps that were damaged with water intrusion and theft of coolant (copper lines). The same permitting issue remains regardless. Without him confirming one way or the other, I assume their limited snowmaking was not only a technical limitation but not wanting to get the notice of DES. I just don't see how he could get a waiver on those units and operate them legally, but I guess weirder things have happened.As I recall he's short compressors but not pumps - there was limited snowmaking on both the tubing and main hills in the last few years, possibly with rental compressors. They've got a couple million gallons of water though it doesn't recharge as well as Magic's. Assuming that the main pumps are online they have the same GPM on Eclipse trails as Magic does running both loops combined.
Compared to Magic, Tenney is short
1. Compressors - Magic has 5000 CFM of electric air, Tenney is stuck renting and maybe also paying for offroad diesel. I expect they can get rentals if they're willing to pay for it.
2. Pump VFDs - Convenient for the crew, but this should show up in the power bill rather than in output.
3. Modern HKDs - Magic has around sixteen portable HKDs, plus around 50-60 towers. Often they're split between HKDs and air hogs because anything above Trick or Talisman is too low pressure for HKDs, and because Green Lift has exactly one permanent HKD tower so they run Rats to use up the rest of the air. Tenney could match Magic's Green Lift low E fleet for ~$160k assuming they order soon enough.
4. Pipe - Tenney had gotten their snowmaking system working enough to run part of the Eclipse pod at least, and they have at pipe for repairs on site. They had more terrain covered than Magic when both systems were fully functional (claimed 70% versus 90%) and both trail pods have abandoned lines and lines without snowmaking.
Tenney's for sure not in as good a shape as Magic overall, but they can order HKDs, rent 5000 cfm of air, and get two routes off the Eclipse pressure tested and mowed for this season. Talisman and Sorcerer and Trick and Upper Carpet and Medium have the Impulse towers that give Magic a snowmaking edge, and Black plus Red easily beat Hornet for uphill capacity and redundancy to the summit. Green Lift terrain at Magic is really hamstrung in marginal by not having fixed towers or more sleds.
He doesn't need 5000 CFM of air until if and when they can pump more water, but renting is their best option. If there is enough power into the base, they can put in a couple 3PH pedestals on the pad and rent a couple towable 1600 CFM outdoor rated rotaries and that would be sufficient. This is what I did some years. Short of that, they have the diesel storage if they want to get diesel towables. More work keeping them going though, but they're easier to get.
VFDs are not an option on diesel pumps (if they were permitted).
There is nothing steep at Tenney, he would be able to get a couple routes covered with a small fleet of the 10' sleds for a year.
But as I said, that pumphouse really needs to be ripped and replaced with electrics and modern controls to be operated by someone without a PHD and to be more efficient.
