SBA Office of Advocacy — analysis of savings from removal of the diesel exhaust fluid (DEF) sensor requirement
U.S. Small Business Administration, Office of Advocacy
Overview
SBA attributes $4.4 billion in annual savings to farmers and $13.79 billion in annual savings to Americans from removal or reconsideration of a specific DEF sensor requirement.
Repeal relevance: If one sensor requirement produces an agency-claimed annual burden of this magnitude, EPA should publish comparable lifecycle cost estimates for the complete aftertreatment system (DPF, SCR, DEF, EGR, OBD induction).
Counterargument: The estimate is attributed to a specific sensor provision. It is not a system-wide repeal cost figure and does not, by itself, prove that removing DPF/SCR/EGR would produce proportionate savings.

What is missing
The specific SBA Office of Advocacy memorandum, comment letter, or economic analysis document that carries the $4.4B (farmers) and $13.79B (aggregate) annual-savings figures attributed to removal of the DEF-sensor requirement. The current landing page is the SBA Advocacy homepage, not the underlying analysis.
What would resolve it
A direct SBA URL (advocacy.sba.gov/... or Regulations.gov docket comment) whose text names the DEF-sensor provision and states the dollar figures. A congressional record excerpt quoting SBA on those numbers would corroborate it but not replace the underlying SBA document.
This record must not be promoted to verified-primary until a specific primary document is located that matches the claim above.
Key passages
Estimated annual savings: $4.4B (farmers), $13.79B (aggregate), attributable to a single DEF sensor requirement — not to repeal of EGR, DPF, SCR or DEF as a system.
