Need Ventura County APCD 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, 166 across 58 holders
From the district's public registry (ERC Certificates by Company report dated Monday, November 2, 2026 (tons/yr)). Register edition retrieved 2026-11-02, last checked 2026-11-02; every certificate is mirrored, with its own page. 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 Ventura County APCD, year by year
From the district's own transaction records, Ventura County APCD — Annual Publication of the Costs of Emission Offsets (HSC §40709.5(e)), and, for sales the district file does not list, from Table V-1 of CARB's statewide §40709.5 reports. Where both record the same sale the district's figure is used and the CARB line is not counted again. Median price per ton as recorded, the number of sales (n) and the low–high range. 140 transactions in all; 4 recorded without a price (3 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); 5 are leases, priced per ton per year as the district annualizes them and listed with the 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 Ventura County APCD
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.
- Buyer and seller negotiate privately and notify District engineering staff (source)
- Seller (registered owner) gives the District a written request stating what portion of the certificate is transferred (Rule 26.4.F.3) (source)
- File Form App003 naming the new owner, signed with an original signature by its responsible official, with the ERC certificate number (source)
- Include an acknowledgment letter from the former owner and the $225 filing fee (source)
- On payment, the District issues a new certificate to the buyer and a revised certificate to the seller (source)
| Rule | VCAPCD Rule 26.4, Section F.3 (Transfer by Registered Owner); fee in Rule 42, Section A.1.c (Adopted 10/22/91, Revised 2/13/96, 1/13/98, 5/14/02, 3/14/06) |
|---|---|
| Form | Form App003 - Permit Application Form - Administrative Change (Transfer of Ownership), covers ERC certificates; plus acknowledgment letter from former owner |
| Fee | Rule 42.A.1.c (last revised 04/08/25): "For each application to make an administrative change to a Permit to Operate, an Authority to Construct or a Certificate of Emission Reduction Credits, an applicant shall pay a filing fee of $225.00"; administrative changes include "transfer of ownership". Rule 26.4.F.3: fee waived if the transfer results from permit activity requiring an ATC and no new certificate is needed for the new owner. App003 also lists a $225 filing fee. (source) |
| Processing time | Not published by the district |
Restrictions the district states: Rule 26.4.F.3: certificate may be transferred "in whole or in part"; registered owner must submit a written request stating what portion is transferred. (source) · Rule 26.4.D.3: shutdown/curtailment ERCs cannot offset a different stationary source with potential to emit over 25 tons/yr ROC or NOx unless the shutdown occurred after August 7, 1977 and the new source is a replacement; the ERC report flags these with a "Limit" check. (source) · Rule 26.4.D.1-D.2: ERCs from units subject to a planned control tactic or further study measure may be reduced to zero or by 50% when a rule implementing the tactic takes effect; this follows the credits ("and any offsets obtained with these emission reduction credits"). (source) · Rule 26.4.F.2: at APCO discretion the District contacts owners about renewing registration; balances not renewed are deemed inactive and transferred to the Essential Public Service Bank. (source) · Rule 26.4.F.4: temporary (leased) use allowed if the District is notified when the project application is filed; project must end or obtain permanent ERCs within 3 years; not allowed for new major sources or major modifications. (source) · Rule 26.5.D: Essential public service credits "shall not be transferable" except when a Permit to Operate is transferred under Rule 20. (source) · Offsets must have a quarterly profile matching the new source's profile at least 80% of the time (Rules 26.2.B.4, 26.6.F). (source) · No discount at transfer stated; Rule 26.4.C discounts (greater of BACT-level or 20% for shutdowns/throughput cuts; 10% for controls/replacements) apply when ERCs are banked. No inter-district transfer provisions found in Rule 26.4. (source) · "The buying and selling of ERCs is a private transaction between companies, but district staff members should be notified". (source)
District staff guidance, 2026-11-02 (Ventura County APCD staff (John Harader), by email to the Exchange in response to its Public Records Act request): A transfer of ERC ownership is filed on Form App003 (Administrative Change) with the parties' contact information, the signed sale or lease agreement, the pollutant, the quantity in tons per year, the total price, the unit price and the certificate number; staff quoted a $225 filing fee. Where the transfer is directly part of an Authority to Construct application already submitted, staff said a separate Administrative Change application is unnecessary, though the same supporting information is still required. Staff guidance for this district only, as written on the date shown. Confirm the current form, fee and rule text with the district before relying on it; it does not apply to any other district. source 1 · source 2 · source 3
District statement, 2026-11-02: District staff wrote that no ERC transactions had occurred in calendar year 2026 as of November 2, 2026. A dated district statement, not a closed-year figure.

How ERCs work in Ventura County APCD
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 Ventura County APCD (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.
