California district records update

Reviewed November 5, 2026. Public records supplied by the districts in response to California ERC Exchange requests, with the dates each record carries. These documents are evidence of banking and administrative actions, not offers to sell or proof of completed market sales. Three kinds of information are kept apart throughout the site: district certificate records (a bank balance of record, which does not establish that anything is for sale), seller-confirmed listings (dated, with the seller's authorization held by the desk), and historical district transactions (recorded by the districts, not transacted through this Exchange).

Imperial County

The district delivered its second records-request response on November 2, 2026: its Transfer of Ownership records for 2015 through 2024 and for 2026, and its Certificates Bank printed October 29, 2026 (pages dated October 28, 2026). The 2025 transfers came in the August 25, 2026 response and are kept as received; the two responses are read as separate sources and never overlap. The request correspondence in the package is not published.

Read into the Exchange's transaction record: 899 transfers (857 for 2015 to 2024, 42 for 2026). The 2026 block's printed totals (287.70 tons, $314,903.50) match its rows; the 2015 to 2024 block's total line is printed as a spreadsheet overflow, so its rows are counted but cannot be checked against a printed figure. 101 rows are recorded at $0.00 (certificate splits into an "A" remainder and a "P" portion, reissues and transfers between related parties); they are kept as transfers, not sales, and are left out of every price statistic. Four rows print a total that differs from tons times price; they are kept as printed and listed in the source notes.

The register now mirrors the October 29, 2026 bank: 328 certificates in the August edition became 331, with 15 certificates added, 12 no longer listed and 9 balances changed, all logged on the changes page. A certificate that left the register is marked as no longer listed, not cancelled: the transfer records show, for example, that 6710 was sold on September 29, 2026 and reappears as 6710P under its new owner. "Available Tons" is the district's recorded bank balance, not a quantity any holder has offered for sale.

Ventura County

The district answered its records request in full on November 2, 2026 with its ERC Certificates by Company report (file named November 1, 2026; printed footer dated Monday, November 2, 2026; both dates are kept in the source notes), a company contact directory (kept privately, never published), its rule and form links, and transfer guidance. The register is mirrored in tons per year with each certificate's quarterly profile and its Limitation flag; the report's footnote says that where the flag is true, ROC or NOx credits on the certificate may not be used for offsets at a stationary source with permitted emissions over 25 tons per year of that pollutant (Rule 26.4.D.3). A false flag means only that this footnote does not apply. Against the July 20, 2026 edition two balances changed; the count of 166 certificates under 58 companies is unchanged.

District staff wrote the same day that no ERC transactions had occurred in calendar 2026 to that date: a dated statement, recorded as such. Historical sale and lease costs come from the district's annual cost reports (sale and lease kept apart, as the district reports them). The staff's transfer guidance (Form App003, the information required, a $225 filing fee quoted) is attributed and dated on the district guide; confirm the current form and fee with the district before relying on it.

Santa Barbara County

On November 2, 2026 the district identified its posted sources as the complete response: the active-certificate ledger, the recent and prior transaction reports, the cost report, Rule 806, transfer form APCD-05T and the fee schedule, all at ourair.org. It does not maintain information on which credits are for sale. The Exchange holds the ledger edition run September 22, 2026 and the cost report dated September 22, 2026; receipt of the November 2 email does not make the underlying reports current as of that date. The district's site blocks automated downloads, so the posted files were not re-fetched on November 3; their report dates are to be confirmed by hand.

San Luis Obispo County

The district supplied its ERC bank log on October 29, 2026 (request PRA2026-119) with a link to Rule 211. The two-page log is headed "Current 10/7/2026; last update 10/16/24"; both dates are kept. It is a ledger, not a certificate list: 102 rows of deposits, withdrawals, name changes and transfers from 1991 to 2024, each with a quarterly profile and separate ERC and community-bank (CB) columns in tons per year. The district's legend says highlighted rows are canceled credits or withdrawals; that highlighting is read from the document, not from its text.

Reconciliation, November 3, 2026: the printed totals (for example NOx 161.859 tons ERC and 39.681 tons CB) equal neither the sum of all rows nor the sum of the unhighlighted rows for any pollutant, under any reading tried (all rows, deposits only, unhighlighted only). No active balance has therefore been loaded, no ledger row is counted as a certificate, and community-bank balances are not treated as private inventory. The log is published as received so a reader can check it.

Monterey Bay

The October 29, 2026 response to PR-26-229 is the district's Summary of Emission Banking Transactions as of October 5, 2026, delivered as an HTML report with an .xls file name: 58 banking actions from 1986 to 2026 under 24 certificate groups, 16 active and 8 expired. Checked November 3, 2026: every active group's closing balance equals the figure already on the register from the district's own October 5 posting, so nothing was added twice; the expired groups are not banked credits; the community bank (ERC-22-002) comes from the district's separate community-bank report. The export has no price column and prints no units, so no price or unit is taken from it; prices stay unknown, not zero. The district states it does not maintain records of credits offered for sale and refers pricing research to CARB. Future requests go through the district's records page.

Glenn County

The district supplied its September 2026 stationary-source register on October 28. It contains seven holder blocks and a separate district bank. Quantities retain quarterly tons. The source requires contacting holders to verify actual quantities and availability.

Source discrepancy: the Calpine/Bechtel SOx fourth-quarter entry prints 2.8, while the recap prints 28. We have preserved the source and have not silently selected a value.

Shasta County

The County closed request 26-2184 on November 5, 2026 by referring to the public records in request 26-1824, which holds its ERC Banking Register Summary updated August 12, 2026. Asked whether further transaction records exist, the County wrote the same day that the most recent transactions are the records in public request 26-968, and that no applications have been received and no ERC certificates issued. Request 26-968 holds two documents, both dated September 20, 2024: the banking register and a Banking Register Summary. All three documents are below.

The August 12, 2026 summary is the newest register available to the Exchange. It lists 34 rows in pounds per quarter with annual pound and ton totals, and its printed annual totals equal the sum of its rows. It is a bank record, not a list of credits offered for sale. The source is published as supplied, with its rows shown in the table below; they have not been added to the searchable certificate inventory, because the summary does not say which rows are earlier certificates since replaced, and such rows must not be added together.

The transactions the County refers to are in the September 20, 2024 banking register: PG&E certificate 18-ERC-01 (NOx 43,660 and CO 16,676 pounds per quarter) was divided into 24-ERC-01, the remainder, and 24-ERC-02, NOx 7,500 pounds per quarter transferred at $0 for use at PG&E in Tehama County. That is an internal transfer, not a market-price comparable. The September 2024 summary lists 24-ERC-02 and has 35 rows; the August 2026 summary no longer lists it and is otherwise row for row the same. The 2024 summary’s printed NOx and CO totals do not equal the sum of its own rows; the 2026 edition’s do. None of the three documents records a priced sale.

Register summary as supplied, updated August 12, 2026 (pounds per year)

Each figure is the sum of the four quarterly figures the district prints for that certificate. An asterisk marks a certificate whose quarters are not all equal; the quarterly figures are in the PDF. One cell is blank in the source (07-ERC-08, CO, fourth quarter).

Antelope Valley

On November 5, 2026 the district answered the Exchange’s records request the day it was received (PRR 26-11-05-057). It pointed to its posted ERC Registry, Rule 1309 and Rule 301, and stated that it has no additional records. No transaction or price records and no transfer form were supplied. This is a statement about the records the district holds, not proof that no transfers occurred.

The posted registry is dated September 18, 2026 and replaces the May 20, 2025 edition held by the Exchange. It lists 10 certificates across four holders, all with status “Available”: three in pounds per day and seven in pounds per year, each kept in its own unit. Compared with the earlier edition, Northrop Grumman certificates AV0028, AV0031 and AV0036 are no longer listed and AV0037 (NOx 21,707 pounds per year) is new. It is a bank record, not a list of credits offered for sale.

Tehama County

On November 5, 2026 the district answered the Exchange’s follow-up request for updates and transaction information with its ERC Registry, printed that day. It wrote that the registry is the only other tracking in its database and that there have been no changes since its previous response, the ERC Bank log printed November 24, 2025. No transaction or price records were supplied beyond the remarks already in that log.

The registry is a scan that lists 29 certificates by company, each with a figure for every pollutant in each of the four quarters. Checked November 5, 2026: every one of the 29 is in the bank log under the same holder, with the same pounds-per-quarter figure in all four quarters. The register on the Exchange is therefore unchanged at 24 certificates across 14 holders, and its balances are confirmed as of November 5, 2026. The registry does not print seven certificates the log carries: four held by the district itself with balances (2001-004, 2001-007, 2007-028 and 2010-001), which stay on the register on the district’s statement that nothing changed and are marked, and three with no balance (2010-003, 2010-004 and 2020-006). It is a bank record, not a list of credits offered for sale. The scan also prints holder addresses and phone numbers, so the document itself is not published.
