Take the following as truth: Adopting the lag structure used in the Tier 2/Gasoline Sulfur and Heavy-Duty Engine/Diesel Fuel RIAs and endorsed by the SAB (EPA-SAB-COUNCIL-ADV-00-001, 1999), we assume a five-year lag structure.
Then the following statement: "Tier 2 uses a ten year lag." is true, false, or inconclusive?
Answer: False
