anchor: Since states now know that EPA has authority to address transport pollution through responses to 126 petitions or by issuing a rule like the NOx SIP Call, we anticipate that states will be turning to these types of control approaches early in the SIP process.
positive: States know that the EPA can address pollution transportation, and can control approaches early in the SIP process.
negative: States know that the EPA can address pollution transportation, and can manipulate SIP processes as late as they want to in the process.
