Proposed rule; amendments.


We are proposing to amend the National Emission Standards for Hazardous Air Pollutants for Source Categories: Generic Maximum Achievable Control Technology Standards to revise the definition of the term “process vent” and to correct some editorial, cross-reference, and wording errors. In the Rules and Regulations section of this Federal Register, we are taking direct final action on the proposed amendments because we view these actions as noncontroversial, and we anticipate no adverse comments. We have explained our reasons for these actions in the preamble to the direct final rule. If we receive no significant adverse comments, we will take no further action on this proposed rule. If we receive significant adverse comments, we will withdraw only those provisions on which we received significant adverse comments. We will publish a timely withdrawal in the Federal Register indicating which provisions will become effective and which provisions are being withdrawn. If part or all of the direct final rule in the Rules and Regulations section of this Federal Register is withdrawn, all public comments pertaining to those provisions will be addressed in a subsequent final rule based on this proposed rule. We will not institute a second comment period on this action. If you are interested in commenting, you must do so at this time.


Comments. We must receive written comments by July 8, 2002, unless a hearing is requested by June 17, 2002. If a hearing is requested, we must receive written comments by July 22, 2002.

Public Hearing. If anyone contacts us requesting to speak at a public hearing by June 17, 2002, a public hearing will be held on June 21, 2002.

Regulated Entities. Categories and entities potentially affected by this action include:

CategoryNAICS *Regulated entities
Industry325199Producers of homopolymers and/or copolymers of alternating oxymethylene units. Producers of either acrylic fiber or modacrylic fiber synthetics composed of acrylonitrile (AN) units. Producers of polycarbonate.
Industry325188Producers of, and recoverers of HF by reacting calcium fluoride with sulfuric acid. For the purpose of implementing the rule, HF production is not a process that produces gaseous HF for direct reaction with hydrated aluminum to form aluminum fluoride (i.e., the HF is not recovered as an intermediate or final product prior to reacting with the hydrated aluminum).

This table is not intended to be exhaustive, but rather provides a guide for readers regarding entities likely to be regulated by this action. To determine whether your facility is regulated by this action, you should carefully examine the applicability criteria in 40 CFR § 63.1103 of the promulgated rule. If you have any questions regarding the applicability of these amendments to a particular entity, consult the appropriate EPA Regional Office representative.

I. What Action Is EPA Proposing?

This proposal would revise the definition of “process vent” and make changes to recordkeeping requirements and technical corrections in 40 CFR part 63, subpart YY. For further information, please see the information provided in the direct final rulemaking notice located in the Rules and Regulations section of today's Federal Register. Start Printed Page 39326

II. What Are the Administrative Requirements for This Action?

Regulatory Flexibility Act (RFA), as Amended by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601 et seq.

The RFA 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 rule amendments on small entities, a small entity is defined as: (1) A small business whose parent company has fewer than 1000 employees; (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.

We believe there will be little or no impact on any small entities because the proposed rule amendments do not impose additional requirements but instead either eliminate cross-referencing, editorial, and wording errors or clarify the applicability of existing requirements of the MACT standards established for acetal resins production, acrylic and modacrylic fiber production, hydrogen fluoride production, and polycarbonate production. The Administrator certifies that this action will not have a significant economic impact on a substantial number of small entities.

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