        <RULE_TITLE>Heavy-Duty Highway Program: Revisions for Emergency Vehicles and SCR Maintenance</RULE_TITLE>
        <ABSTRACT><![CDATA[On January 18, 2001, EPA published a rule promulgating more stringent NOx and PM standards for heavy duty highway engines ("the heavy-duty highway rule"), entitled "Control of Air Pollution from New Motor Vehicles: Heavy-Duty Engine and Vehicle Standards" (66 FR 5001). EPA has previously published clarifications and technical amendments to that final heavy-duty highway rule. This action would provide additional clarification, modifications and technical amendments to the regulations for heavy-duty highway engines and would clarify, modify and technically amend some provisions in 40 CFR parts 86 and 1068. This action would assist regulated parties to comply with requirements by clarifying and/or simplifying those requirements. Specifically, this action would provide flexibility for on-highway emergency-response vehicles with respect to emissions of particulate matter and oxides of nitrogen. This action would also amend the requirements for emission-related scheduled maintenance with respect to replacement of diesel exhaust fluid, which is used in selective catalytic reduction control systems. This action is not expected to result in significant changes in regulatory burdens or costs.]]></ABSTRACT>
