No ROG / VOC or PM10 transaction is on record for Butte County AQMD in the 2022 or 2023 statewide reports or in the district transaction records the Exchange holds. For a reference point: 2023 ROG / VOC medians elsewhere in California ran from $1,100 (Imperial County) to $174,845 (San Joaquin Valley); 2023 PM10 medians elsewhere in California ran from $485 (Imperial County) to $460,000 (South Coast). Credits only work in the district that banked them, so local scarcity, not the statewide range, sets the price here. All recorded prices.
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 Butte County 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 Butte County AQMD, or its air basin with district board approval under Health & Safety Code §40709.6. District office: (530) 332-9400.
