On January 31, 2012 EPA proposed to establish nonconformance penalties (NCPs) for heavy-duty diesel engines. On that same day, we also promulgated an Interim Final Rule to establish interim NCPs for heavy heavy-duty diesel engines. We held a public hearing on March 5, 2012, at which oral comments on the NPRM were received and recorded. Additionally, a written comment period remained open until April 4, 2012. A complete list of organizations, their abbreviations, and individuals that provided comments on the NPRM is contained in this document. This Response to Comments contains a summary of all comments we received on the NPRM as well as our responses to these comments. |
