No SOx transaction is on record for Feather River AQMD in the 2022 or 2023 statewide reports or in the district transaction records the Exchange holds. For a reference point: the only 2023 SOx trades recorded statewide were in Yolo-Solano, at a median of $17,000 per ton. Credits only work in the district that banked them, so local scarcity, not the statewide range, sets the price here. All recorded prices.
Arithmetic only — the recorded volume multiplied by the Feather River median price recorded for each pollutant in 2023. 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.

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 Feather River AQMD, 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 Feather River AQMD, or its air basin with district board approval under Health & Safety Code §40709.6. District office: (530) 634-7659.
