Not currently at this shelter but my last shelter (Animal Care and Control Team of Philadelphia - ACCT Philly) did partner with New Leash On Life.
I don't think there were any specific SOPs written out - or if there were, I honestly can't recall seeing them. The way that it essentially worked was that when we first started in the rescue office, we were given a list of parameters of types and behaviors of dogs that New Leash and co were able to handle. When we were told that New Leash was coming by in the next week or so, the Lifesaving Team (rescue/foster) would then give a short list of a handful of dogs we think fit the bill of the previously mentioned ideal candidates, then New Leash managers would come to do evaluations, and then they'd set up a pickup time in the coming days for the final cut. They'd take about 5 to 6 dogs. At one time, they were trying to have weekly visits for training/enrichment instead of taking the dogs as placement options were a bit low but that didn't seem to pan out.
I have been elsewhere for the last year and a half, so unfortunately I'm not 100% sure if they're running it anymore but I would recommend giving a call or email to the shelter and getting in touch with Sarah Barnett and/or Tara Schernecke, who are the Interim Co-Executive Directors!
