Need Sacramento Metro AQMD credits for an air permit?
Tell the desk the pollutant, the tons per year and the permit date. You get a written supply check: the register certificates that look like candidates (each one pending the district's eligibility review for your project), whether their holders have confirmed availability, the last recorded prices in the district's own units, the transfer steps and fee, and how payment and transfer timing are set (by the written transaction agreement between buyer and seller; the Exchange never holds funds). No fee for the check, and your request is not published.
Banked ERC certificates of record, 203 across 32 holders

These are banked credits, the registry shows what exists, not what the holder has committed to sell. Open the interactive registry to search, view pollutant breakdowns, and send an inquiry.

Every recorded sale in Sacramento Metro AQMD, year by year
From Table V-1 of CARB's statewide §40709.5 reports, which list each sale the districts reported (1994 to 2023; the 2006 and 2007 reports are scans that could not be read). The district publishes no sale-by-sale record of its own. Median price per ton as recorded, the number of sales (n) and the low–high range. 154 transactions in all; 20 recorded without a price (20 of them recorded at $0.00: transfers without a cash price, such as splits, reissues, barters and transfers between related parties, kept as transfers, not priced sales). Prices are shown as printed, including a few nominal ones ($1–$100 per ton) that sit at the low end of some ranges. Download every transaction (CSV).

Transferring ERCs in Sacramento Metro AQMD
The district's own procedure, step by step, from its rules and forms (checked 2026-10-04). Every deal room on the Exchange follows these steps.
- Transferor (seller) signs a written instrument authorizing and memorializing the transfer (source)
- Within 30 days of that writing, the transferee (buyer) surrenders the transferor's ERC certificate and a copy of the signed writing to the Air Pollution Control Officer (source)
- District reviews, issues a new certificate in the buyer's name, issues a remainder certificate to the seller for any partial transfer, and records the transfer in the Register (source)
| Rule | SMAQMD Rule 204, Section 410 (Registration), subsections 410.5-410.6; Section 411 (Emission Reduction Credits Register) (Adopted 12-15-92; amended 9-5-96) |
|---|---|
| Form | No transfer form published |
| Fee | No transfer-specific fee published. Rule 301 Section 315 (Emission Reduction Credit Banking Fee) covers requests "to deposit emission reduction credits in the District credit bank or to withdraw emission reduction credits" at actual staff hours, at the Section 308.12 time-and-materials rate of $282.22 per hour (Rule 301 CPI adjustment 7-1-26). Whether a transfer is billed under Section 315 is not stated. (source) |
| Processing time | Not published by the district |
Restrictions the district states: Rule 204 Section 410.5: transferor's certificate and the signed transfer writing must be surrendered by the transferee "within 30 days of the date of the writing authorizing the transfer"; "The District may refuse to recognize any transfer of emission reduction credits that does not comply with the requirements of this section." (source) · Rule 204 Sections 410.6 and 411.2: surrendered certificate is filed in the Register and marked with the new certificate number(s) and credits transferred; Register records original and new certificate numbers, new owner name/address, and number of credits transferred. (source) · Rule 204 Section 410.1: a certificate is not evidence of compliance or "a representation or assurance" that the credits "are available from the emission credits Register." (source) · Rule 202 Section 302.6 (amended 8-23-12): offsets from another district may be used only after APCO review and a determination they meet District rules and H&SC 40709.6; an offset ratio not less than Section 303 levels applies "to discount the offsets." No discount at the time of transfer is stated in Rule 204. (source)

How ERCs work in Sacramento Metro AQMD
Emission Reduction Credits are banked, district-certified reductions in NOx, ROG/VOC, PM10, SOx, or CO. Businesses building or expanding in the district may be required under New Source Review to purchase ERCs to offset new emissions before an air permit issues. Credits are generally usable only within Sacramento Metro AQMD (or its air basin with district board approval, Health & Safety Code §40709.6), which is why local scarcity sets the price. The district verifies reductions and records every transfer.
