Facts

EPA designated portland cement plants as a source category under Section 111 and proposed particulate and opacity standards for new or modified plants, accompanied by a Background Document. EPA stated that the standards were based on source testing, contractor testing, and literature, but it did not timely disclose the detailed test results and methodologies for key tests at the Dragon and Oregon cement plants before promulgating the rule. Cement manufacturers argued that EPA failed to comply with NEPA, failed adequately to consider costs, and had not adequately demonstrated the achievability of the standards. After later disclosure of the data, an engineer submitted a detailed critique asserting that the Dragon test was grossly erroneous, but EPA did not respond substantively to that critique after remand.

Issue

Whether EPA's promulgation of new source performance standards for portland cement plants under Section 111 was valid when EPA did not prepare a NEPA impact statement, considered costs in the manner it did, and relied on testing and literature that were not fully disclosed or adequately explained to permit meaningful comment and review. More specifically, the court considered whether Section 111 required a NEPA statement and whether the record adequately demonstrated that the standards were achievable.

Rule

For EPA determinations under Section 111 of the Clean Air Act, NEPA does not require a separate impact statement because Section 111, properly construed, requires the functional equivalent of one through a statement of reasons addressing environmental considerations and costs. In Section 111 rulemaking, EPA must provide enough disclosure of the factual basis, test data, and methodology underlying proposed standards to allow meaningful comment, must respond to material criticisms that call the basis of the rule into question, and may project from existing technology only within the bounds of reasonableness as to whether a standard has been adequately demonstrated and is achievable. EPA must take economic costs into account, but it need not prepare a quantified cost-benefit analysis or justify disparities between industries by affirmative inter-industry comparisons.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

EPA promulgates a new-source emissions standard for fiberglass kilns under Clean Air Act § 111. The rulemaking record includes a statement of reasons discussing environmental consequences, countervailing pollution effects, compliance costs, comments from other agencies, and materials available for judicial review, but EPA did not prepare a separate NEPA impact statement.

If manufacturers challenge the rule solely because EPA omitted a separate NEPA impact statement, what is the strongest answer?

Explanation. For EPA determinations under § 111, the court recognized a narrow NEPA exemption because the statutory scheme requires the functional equivalent of an impact statement: consideration of environmental factors and costs, a statement of reasons, opportunity for comment, and judicial review. The majority rejected a broad all-agency NEPA syllogism and grounded its holding specifically in § 111’s structure.
