Reference value at recorded prices
Arithmetic only, this certificate's volume multiplied by the Imperial County median recorded for each pollutant in 2022–2026, shown as a range because the medians moved between years. Where the yearly medians are more than three times apart there is no usable reference and none is given. Not an appraisal, an offer or a prediction.
| Pollutant | Tons / year | × recorded median | Reference |
|---|---|---|---|
| NOx | 1.46 | $2,500– | $3,650– |

How a transfer works in Imperial County
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 Imperial County APCD, which verifies the banked reductions, records the transfer and re-issues the certificate, or its remaining balance, in the buyer's name. Credit use is subject to district rules. Some interdistrict uses are possible with required approvals under Health & Safety Code §40709.6. District office: (442) 265-1800.
