Need Monterey Bay ARD 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, 17 across 17 holders
From the district's public registry (Active ERC Registry (Summary of Emission Banking Transactions) as of October 5, 2026; Community Bank ERCs as of October 5, 2026 (volumes in tons)). Register edition retrieved 2026-10-06, last checked 2026-10-21; 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.

Transferring ERCs in Monterey Bay ARD
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 arrange the transfer directly; MBARD does not set price or arrange trades (source)
- Registered holder completes the Application for Transfer of ERCs, signed by its responsible official, and attaches a letter acknowledging relinquishment of the ERCs, the amount to transfer and the buyer's company and contact (source)
- Holder pays all outstanding obligations to MBARD (including ERC registry fees) - Rule 215 Sec. 4.6; Rule 300 Sec. 6.1 (source)
- For a partial transfer, surrender the Banking Certificate so a new certificate can be issued reflecting the partial transfer - Rule 215 Sec. 4.6 (source)
- Transfer becomes effective when MBARD informs the holder it has been received and recorded in the ERC Registry - Rule 215 Sec. 4.6 (source)
| Rule | MBARD Rule 215, Section 4.6 (Procedure for Transferring ERCs) (Adopted October 20, 1982; last revised 6-19-02) |
|---|---|
| Form | Application for Transfer of Emission Reduction Credits (form title reads "APPLICATION FOR TRANFER OF EMISSION REDUCTION CREDITS"); applicant must "Attach a letter acknowledging relinquishment of ERCs, the amount of ERCs to transfer, and the company name and contact person to transfer the ERCs." |
| Fee | No separate ERC transfer fee is listed in Rule 300 or Rule 301. Rule 215 Section 4.6 requires "payment of all outstanding obligations to the District"; the transfer form states the applicant agrees "to pay any and all fees required by District rules for processing this application and for the transfer". Rule 300 Section 6.1: "ERC Banking Certificates are not in effect and cannot be traded or used in any manner unless the appropriate fees required herein have been fully paid." Related fees, Rule 301 Table 1 (FY 2026-2027, amended 6-17-26): ERC Registry Fee (Sec. 6.1) $754; Annual Registry Fee (Sec. 6.1.2) $252; Hourly Staff Rate $182. (source) |

Restrictions the district states: Rule 215 Section 4.6: "Sources operating in violation of any District rule or regulation shall not be eligible to transfer ERCs or receive transferred ERCs." (source) · Rule 215 Section 4.6: transfer requires "payment of all outstanding obligations to the District"; Rule 300 Section 6.1: certificates cannot be traded unless ERC fees are fully paid (registry fees due within 60 days of billing). (source) · Rule 215 Section 3.1.3 / 5.1.1: new ERCs entered into the Registry are "discounted in value by 10 percent" at deposit into the Community ERC Account (discount applies at banking, not at transfer). Section 4.6: ten percent of ERCs used to offset temporary sources go to the Community ERC Account. (source) · Rule 215 Section 5.3.4: "Community ERCs cannot be transferred or banked by a source, except back into" the Community ERC Account. (source) · Rule 215 Section 4.1.2: the ERC Registry "shall be accessible to the public" (log of all entries, cumulative tally, account per depositor). District posts the Active ERC Registry and Community Bank ERCs PDFs (as of 9/5/2025). (source) · District ERC page: "Transfers of ERCs are arranged directly between transferors (sellers) and transferees (buyers)"; MBARD "does not set the price of credits or arrange transactions". The page refers buyers to CARB's annual statewide ERC transaction summary for prices. (source) · Offset use location (Rule 207 Section 4.3, Table 4.3): ratios range from 1:1 (same source) to 2.5:1 (non-Area A, different air basin) for nonattainment pollutants; offsets generally within a 15-mile radius unless an air quality analysis supports otherwise.

How ERCs work in Monterey Bay ARD
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 Monterey Bay ARD (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.
