As I read the grading law from the above link, it looks like between now and 1/1/16 you can use either, as of 1/1/16 you must use the new grading stds. That is essentially what NY is, except, we must start packing under the new grades as of 1/1/15, but we can still sell any old grade packed prior to 1/1/15 that is on our shelves. Once we get to 1/1/16 all must be using new grading system.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
