South Coast Air Quality Management District

Amend Regulations IX - Standards of Performance for New Stationary Sources and 
X - National Emission Standards for Hazardous Air Pollutants

SYNOPSIS: 

Local air districts are authorized by EPA to implement federal standards set in 40 Code of Federal Regulations (CFR) Part 60, Standards of Performance for New Stationary Sources and Part 61, National Emission Standards for Hazardous Air Pollutants (HAPs). Periodic amendments to Regulations IX and X incorporate new or amended standards by reference. Nine actions regarding NSPS and one NESHAP are proposed for incorporation into Regulations IX and X, respectively. Three of these changes will reduce HAPs. The others include clarifications and corrections, administrative changes, and changes to test methods and monitoring.

COMMITTEE:

Background

The U.S. EPA periodically promulgates New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAPs). NSPS govern the operation of all new, modified, or reconstructed sources of air pollution identified in Part 60 of the Code of Federal Regulation (CFR). NESHAPs govern the operation of new and existing sources specifically identified in Part 61 of the CFR and emitting substances that pursuant to Section 112 of the Clean Air Act Amendments, have been designated as hazardous air pollutants. In order to administer and enforce NSPS and NESHAPs at the local level, AQMD’s Governing Board initially adopted by reference the NSPS federal standards as AQMD Regulation IX, and the NESHAPs federal standards as Regulation X, on December 3, 1976. The Board has since amended these regulations to incorporate new or amended standards as necessary. In 1997, EPA delegated and redelegated its authority for specific Sections of 40 CFR Parts 60 and 61, as listed in the April 23, 1997 Federal Register, Volume 62, No. 78, 19679 – 19682. Regulation IX was last amended April 21, 2000 and Regulation X was last amended August 13, 1999.

The 1990 Amendments to the federal Clean Air Act called for the EPA to establish maximum achievable control technology (MACT) standards for new and existing major sources of hazardous air pollutants, starting within two years of enactment and finishing within ten years. The MACT standards are published in the CFR as Part 63. EPA delegated authority for the implementation and enforcement of Part 63 to the AQMD on February 27, 1997. However, the AQMD has not established a separate regulation to encompass those standards but implements them directed to sources covered by the Part 70 program (Title V). The AQMD has sought and been granted equivalency with the MACT for Perchloroethylene Air Emission Standards for Dry Cleaning Facilities, through District Rule 1421. At this time, staff is seeking equivalency on a number of other MACT standards and is not herein incorporating by reference the standards set through 40 CFR Part 63.

Proposal

Nine NSPS actions for which the AQMD has delegation of authority have been promulgated by EPA during the past year are now proposed for incorporation by reference into Regulation IX. Three of these actions pertain to Appendix A – Test Methods, and Appendix B – Performance Specifications, which do not appear in the rule but are enforced by the District. There is one NESHAP action for which the AQMD has delegation of authority, that has been promulgated by EPA during the past year. This Board letter and its attachments serve as the staff report for proposed amendments to Regulations IX and X.

All new sources of air pollution and all modified or reconstructed sources of air pollution are required to comply with the more stringent of the applicable federal, state, and local standards, criteria, and requirements set forth in Regulation IX or other AQMD rules. The same is true for new and modified sources identified by source category for control in the NESHAPs. These standards are in effect and enforceable by AQMD pursuant to § 301, in conjunction with Sections 110, 111(c)(1), and 112(d)(1) of the federal Clean Air Act, regardless of whether AQMD incorporates them by reference into Regulations IX and X. Nonetheless, adoption of NSPS and NESHAPs by reference into Regulations IX and X helps affected sources by providing a single point of reference for determining which federal and local requirements apply to their specific operations.

The nature of these actions includes three promulgations of standards and guidelines which will result in a reduction of emissions of several hazardous air pollutants: 1) Subparts CCCC and DDDD – December 1, 2000 (Standards of Performance for Commercial and Industrial Solid Waste Incineration Units for Which Construction is Commenced After November 30, 1999 or for Which Modification or Reconstruction is Commenced on or After June 1, 2001; and Emissions Guidelines and Compliance Times for Commercial and Industrial Solid Waste Incineration Units that Commenced Construction On or Before November 30, 1999); 2) Subpart AAAA – December 6, 2000 (Standards of Performance for New Stationary Sources: New Small Municipal Waste Combustion Units); and 3) Subparts A, B, and BBBB – December 6, 2000 (Emission Guidelines for Existing Small Municipal Waste Combustion Units). Additionally, the promulgations include: clarifications, editorial changes, technical corrections, typographical corrections and administrative changes, reduction of recordkeeping and reporting burden, and changes to test methods and monitoring equipment.

Public Workshops

EPA held public workshops with public comment periods as part of its rule development process. No public workshops were held by AQMD since the proposed amendments incorporate by reference existing legal requirements and therefore, do not significantly affect air quality or emissions limitations.

Regulations IX and X Proposal

Tables 1 and 2 list NSPS and NESHAPs, respectively, currently proposed for incorporation by reference into AQMD Regulations IX and X.¹

Anyone wishing to view this material may do so by contacting AQMD’s Public Information Center at (909) 396-3600.

CEQA and Socioeconomic Impacts

Staff has reviewed the proposed amendments to Regulations IX - Standards of Performance for New Stationary Sources, and X – National Emission Standards for Hazardous Air Pollutants, pursuant to state CEQA Guidelines § 15002(k)(1) - Three Step Process, and has determined that the proposed amendments are exempt from CEQA pursuant to state CEQA Guidelines § 15268 - Ministerial Projects. AQMD proposes to incorporate by reference federal NSPS requirements into Regulation IX and NESHAP requirements into Regulation X. Because AQMD exercises no discretion with regard to the proposed project, it is considered to be ministerially exempt. Furthermore, the proposed amendments are categorically exempt because they are considered actions to protect or enhance the environment pursuant to CEQA Guidelines §15308 - Class 8 Categorical Exemption. If approved by the Governing Board, a Notice of Exemption (NOE) will be prepared for the proposed project pursuant to state CEQA Guidelines §15062 – Notice of Exemption, and mailed to the county clerks of Los Angeles, Orange, Riverside, and San Bernardino counties.

No socioeconomic impact assessment was performed for the proposed amendments, since they will not significantly affect air quality or emissions limitations. In addition, the proposed amendments are verbatim adoption of current NSPS and NESHAP requirements and thus, do not impose new requirements in addition to the federal regulations.

AQMP and Legal Mandates

These federal requirements are not included in the AQMD’s AQMP. Section 301, in conjunction with Sections 110, 111(c)(1), and 112(d)(1) of the federal Clean Air Act authorize EPA to delegate authority to implement and enforce standards and related compliance times for new, modified, or reconstructed sources of air pollution set forth in 40 CFR Part 60, and for new and existing sources of air pollution set forth in 40 CFR Part 61, to local air districts. Adoption of new and amended NSPS into AQMD Regulation IX and NESHAP into Regulation X by reference formally recognizes AQMD’s authority to implement and enforce these federal regulations at the local level.

Implementation Plan

Proposed amendments do not materially affect the structure or function of existing programs associated with the implementation of Regulation IX - Standards of Performance for New Stationary Sources, and Regulation X – National Emission Standards for Hazardous Air Pollutants, or any other AQMD rules. Staff is available to assist those facilities affected by the proposed amendments.

Resource Impacts

Current AQMD resources are sufficient to implement and enforce proposed Regulations IX and X amendments.
