Reference value at recorded prices
Arithmetic only, the recorded volume multiplied by the Imperial County median price recorded for each pollutant in 2022–2026, 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.
| Pollutant | Volume | × recorded median | Reference |
|---|---|---|---|
| NOx | 9.11 t | $2,500– | $22,775– |
| PM10 | 8.42 t | $425– | $3,579– |
| All pollutants with a usable Imperial County reference | $26,354– | ||
How a transfer works in Imperial County
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 Imperial County APCD, which verifies the banked reductions, records the transfer, and re-issues the certificate (or the 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. District ERC program page.
