About the data on this page

Bank details, status and credit balances are mirrored from the USACE RIBITS registry, the federal public record for mitigation banks. What we call a “credit sale” is a credit withdrawal — the entry written in the federal credit ledger when credits are committed to a permit. At commercial banks a withdrawal generally represents a sale; at a single-client bank it offsets the sponsor’s own project. The figures count ledger transactions, not distinct purchases — one purchase may produce several withdrawals — and we count entries rather than credits moved, because credit classes are different units and cannot be added together. Each bar in a sales chart counts the credit sales recorded in that calendar year — withdrawals from the federal ledger, not quantities of credits. The final bar is the year in progress and is shown in a different color. No bars means no sales in those years.

The operator grouping is ours, not from RIBITS. The federal registry records a sponsor for each bank but lists no parent company. We identify operators by matching sponsor names and contact details across bank records, reviewed by hand. We only display operators with at least five banks.

Contact details are mirrored from the bank’s own entry in the USACE RIBITS registry. Where RIBITS designates a Sales point of contact, we display it more prominently to get you to a contact person more quickly. The map on this page is drawn live from the EPA NEPAssist RIBITS MapServer when you load it. Nearby banks are the closest banks that currently have credits to sell, by straight-line distance between registered locations. It is a proximity list, not a statement that those banks can serve your site.
