final rule regulating secondhand, or “environmental,” tobacco smoke in the workplace. Another panel of this court, citing Telecommunications Research & Action Center v. FCC, 750 F.2d 70 (D.C.Cir.1984), ordered ASH’s filing to be treated as a petition for a writ of mandamus and referred it to us for decision. See D.C.CiR. Role 21(a).

When we heard the case, ASH’s counsel confirmed that smoking was forbidden in ASH’s offices. This raised doubts about ASH’s claim that it had standing in its representative capacity. If ASH’s employees were not encountering secondhand smoke in their offices, who was ASH purporting to represent? Organizations are sometimes able to sue on behalf of their members. Hunt v. Washington State Apple Advertising Comm’n, 432 U.S. 333, 343, 97 S.Ct. 2434, 2441, 53 L.Ed.2d 383 (1977). But as a charitable trust, ASH did not fit the description of a traditional membership association. We wondered whether a trust’s financial contributors should be treated ás the equivalent of “members,” so that the trust could appear for .them and derive its standing from their injuries and need for redress. Contrast American Legal Found. v. FCC, 808 F.2d 84, 90 (D.C.Cir.1987).
ASH furnished post-argument affidavits at our request. Some are from ASH’s donors. We do not rely on them, and thus do not decide the novel issue of derivative standing posed by a charitable trust. Another affidavit, submitted by the chairman of ASH’s board of trustees, convinces us that ASH has standing on standard grounds. This gentleman has sworn that in his regular employment at the New York Mercantile Exchange, he is exposed to secondhand tobacco smoke and suffers from its effects. See 5 U.S.C. § 702. We have no doubt that ASH may act in a representative capacity for the members of its board of trustees, and may treat their interests as its own for the purposes of establishing its standing to sue when those interests “are germane to the organization’s purpose,” Hunt, 432 U.S. at 343, 97 S.Ct. at 2441. Cf. Mountain States Legal Found. v. Costle, 630 F.2d 754, 767-68 (10th Cir.1980). The injury to the interests of one of its board members is therefore enough to allow ASH to proceed with the lawsuit. Warth v. Seldin, 422 U.S. 490, 511, 95 S.Ct. 2197, 2211-12, 45 L.Ed.2d 343 (1975); Lujan v. Defenders of Wildlife, 504 U.S. 555, 563, 112 S.Ct. 2130, 2137-38, 119 L.Ed.2d 351 (1992).

For the last few years, ASH has been prodding the Administration into issuing a final rule regulating secondhand tobacco smoke as an occupational carcinogen. The history of some of these efforts is recounted in Action on Smoking & Health v. Department of Labor, 28 F.3d 162, 165 (D.C.Cir.1994), in which we dismissed ASH’s petition to require rulemaking because in April 1994, while the case was pending, the agency issued a Notice of Proposed Rulemaking on Indoor Air Quality dealing with contaminants including tobacco smoke. Among other restrictions in the proposed rule was a prohibition against smoking in all' indoor workplaces except certain designated smoking areas with adequate ventilation systems. 59 Fed.Reg. 15,968, 16,037 (1994).
Public hearings on the proposal began in September 1994 and continued through March 1995. More than 400 witnesses testified. Because of the size and complexity of the record, an administrative law judge several times extended the deadline for filing post-hearing comments and replies. By the end of it, the Administration had amassed the largest record in its rulemaking history— more than 335,000 pages. ASH did not participate in the hearing.
The Administration has not yet issued or refused to issue a final rule, nor has it indicated when it would do so. From this ASH concludes that the agency is violating its regulatory timetable and that the court ought to step in and order compliance. At the center of ASH’s case is the Administration’s “Cancer Policy,” 29 C.F.R. §§ 1990.101 to 1990.147. Adopted in January 1980, this Policy “establishes the criteria and procedures under which substances will be regulated by OSHA as potential occupational carcinogens.” Id. § 1990.111(a).
