opinion: Opinion PER CURIAM.
  ON PETITIONS FOR LIMITED REHEARING
  PER CURIAM:
  The Environmental Protection Agency (the “Agency”), respondent in the original proceeding, and representatives of the automotive industry intervening on behalf of the Agency have petitioned for a limited rehearing of the judgment of the en banc court set out at 847 F.2d 843 (D.C.Cir.1988). In the per curiam opinion accompanying that judgment, the court stated that although its members were evenly divided as to the existence of Article III standing on the original petitioners’ part, we would reinstate the panel decision in which standing had been found and a disposition made on the merits. This action was taken in light of the fact that there was no district court opinion and the agency itself had no cause to pass on the Article III standing issue. We ruled, however, that the reinstatement of the panel opinion was to have no prece-dential effect in future cases as to standing.
  After consideration of the arguments set forth in the petitions for rehearing submitted by the Agency and intervenors and in original petitioners’ reply thereto, we have decided that our original disposition was not an appropriate one. We now hold that as a majority of the en banc court was unable to satisfy itself that the court had jurisdiction, the court should not have taken any affirmative action on the merits, including reinstatement of the panel opinion. Accordingly, we now vacate the opinion and judgment of May 17, 1988, and deny the original petition for review, leaving the Agency decision in effect.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private organization or association", specifically "other". Your task is to determine what subcategory of private association best describes this litigant.
