SAPRC vs. Carbon Bond IV

  The MIRs used in developing reactivity-based regulations are based on the SAPRC mechanism. However, the U.S. Environmental Protection Agency recommends that the Carbon Bond IV (CBIV) chemical mechanism be used as the regulatory mechanism for State Implementation Plan (SIP) evaluation. Therefore, the effects of control strategies based on alternative formulations that are deemed to meet reactivity limits are being evaluated using the CBIV imbedded in the gridded 3-D Urban Airshed Model. Questions specific to this topic is:


Are the benefits of a regulation based on SAPRC-based MIRs appropriately evaluated using the CBIV mechanism (i.e., Ozone SIP)?


In what ways would the results be expected to differ if the same mechanism were used for both MIR determination and SIP modeling evaluations?

2:30 p.m.
