Proposed rule; amendments.


On April 11, 2002, pursuant to section 112 of the Clean Air Act (CAA), the EPA issued national emission standards to control hazardous air pollutants emitted from catalytic cracking units, catalytic reforming units, and sulfur recovery units at petroleum refineries. This proposal would amend several sections of the existing standards. The proposed amendments would revise the affected source designations and add new compliance options for catalytic reforming units that use different types of emission control systems, new monitoring alternatives for catalytic cracking units and catalytic reforming units, and a new procedure for determining the metal or total chloride concentration on catalyst particles. The proposed amendments would also defer technical requirements for most continuous parameter monitoring systems, clarify testing and monitoring requirements, and make editorial corrections to improve implementation of the standards and to promote better understanding of their requirements.

In the Rules and Regulations section of this Federal Register, we are issuing these amendments as a direct final rule. We are making these amendments as a direct final rule without prior proposal because we view the revisions as noncontroversial and anticipate no adverse comments. We have explained our reasons for these revisions in the direct final rule.

If we receive any significant adverse comment on one or more distinct amendments in the direct final rule, we will publish a timely notice of withdrawal in the Federal Register informing the public which amendments will become effective and which amendments are being withdrawn due to adverse comment. We will address all public comments in a subsequent final rule. If no significant adverse comments are received, no further action will be taken on this proposal and the direct final rule will become effective as provided in that notice.

The regulatory text for the proposal is identical to that for the direct final rule published in the Rules and Regulations section of this Federal Register. For further supplementary information, see the direct final rule.

II. Statutory and Executive Order Reviews

For information regarding other administrative requirements for this action, please see the direct final rule that is located in the Rules and Regulations section of this Federal Register.

The Regulatory Flexibility Act generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the Agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

For purposes of assessing the impacts of today's proposed amendments on small entities, a small entity is defined as: (1) A small business that has no more than 1,500 employees and no more than 75,000 barrels per day capacity of petroleum-based inputs, including crude oil or bona fide feedstocks; [1] for NAIC code 32411; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; or (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.

After considering the economic impacts of today's proposed amendments on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. In determining whether a rule has a significant economic impact on a substantial number of small entities, the impact of concern is any significant adverse impact on small entities, since the primary purpose of the regulatory flexibility analyses is to identify and address regulatory alternatives which minimize any significant economic impact of the proposed rule on small entities (5 U.S.C. 603-604). Thus, an agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, or otherwise has a positive effect on the small entities subject to the rule. The proposed amendments make improvements to the existing standards by adding new compliance options, allowing more time for certain new or reconstructed affected sources to comply, and clarifying monitoring and testing requirements. We have, therefore, concluded that today's proposed amendments will have no adverse impacts on any small entities and may relieve burden in some cases. We continue to be interested in the potential impacts of the proposed rule on small entities and welcome comments on issues related to such impacts.
