Arithmetic only — the recorded volume multiplied by the San Joaquin Valley median price recorded for each pollutant in 2020–2026, shown as a range because the medians moved between years. Not an appraisal, an offer, or a prediction; actual bids depend on the buyer's permit deadline, the lot size, how many trades the median rests on, and what else is available in the district.

| NOx | 26.4 t | $9,500– | $251,000– |

The buyer and holder agree a price privately. The transfer package — the holder's authorization, the purchase agreement, and the district's transfer forms — goes to San Joaquin Valley APCD, which verifies the banked reductions, records the transfer, and re-issues the certificate (or the remaining balance) in the buyer's name. Credits are generally usable only inside San Joaquin Valley APCD, or its air basin with district board approval under Health & Safety Code §40709.6. District office: (559) 230-6000.
