You're correct. Read and weep, here it is, 46 pages in all. All that data they collected on us at the BAR over the years, would appear to be our undoing. SPCNS cars pollute too much. It appears though that it only applies to SPCNS cars after the 500 which could receive biennial inspections.

BTW, page 10 has a really nice flow chart of the SPCNS registration process.
