{"abstract":"This rulemaking amends the regulations applicable to compression-ignition nonroad engines at or above 37 kilowatts (kW) to address two disruptive situations that have arisen regarding the implementation of regulations applicable to these nonroad engines. No air quality impact is expected from these amendments. These amendments will allow nonroad vehicle manufacturers to use certified on-highway engines in nonroad vehicles that are constructed from on-highway vehicles or that must use public roads between job sites. These amendments also will allow engine manufacturers to provide uncertified replacement engines to repower pre-regulation nonroad equipment when that equipment experiences major engine failure.","action":"Direct final rule.","agencies":[{"raw_name":"Final Rule"},{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/1996/11/12/96-28545.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"86","title":40},{"chapter":null,"citation_url":null,"part":"89","title":40}],"citation":"61 FR 58102","comment_url":null,"comments_close_on":"1996-12-12","correction_of":null,"corrections":[],"dates":"This final rule is effective January 13, 1997 unless adverse or critical comments are received by December 12, 1996.
