Need Butte County 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.

How ERCs work in Butte County 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 Butte County 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.
