NOTICE IS HEREBY GIVEN that a series of 

regional public hearings on the matter of the 

Proposed Supplement to the 24-hour PM2.5 State 

Implementation Plan (SIP) for the South Coast Air 

Basin (Supplement) will be held at the above 

locations throughout the District’s jurisdiction, at 

which time evidence will be taken and all 

interested persons will be heard by the South 

Coast Air Quality Management District 

(SCAQMD) Governing Board.

NOTICE IS FURTHER GIVEN that the 

SCAQMD Governing Board will consider 

adoption of the Supplement on February 6, 2015,

at 9 am at a public hearing in the SCAQMD 

Auditorium, 21865 Copley Drive, Diamond Bar, 

CA 9176, at which time evidence will be taken 

and all interested persons will be heard by the 

SCAQMD Governing Board.

NOTICE IS FURTHER GIVEN that, upon 

adoption, the Supplement will be submitted to the 

California Air Resources Board (CARB) and the 

U.S. Environmental Protection Agency (EPA) for 

inclusion into the SIP.

NOTICE IS FURTHER GIVEN that the 2012 Air 

Quality Management Plan (AQMP) was designed 

to address the PM2.5 SIP requirements of the 

federal Clean Air Act for the South Coast Air 

Basin (Los Angeles County, Orange County, San 

Bernardino County and Riverside County). The 

2012 AQMP was approved in December 2012 and 

AQMP amendments approved in February 2013; 

subsequently submitted to the CARB and the U.S. 

EPA for inclusion into the SIP. The 2012 AQMP 

included the following elements:

• A 24-hour PM2.5 attainment 

demonstration for 2014;

• An analysis of Reasonably Available 

Control Technology (RACT);

• 2014 transportation conformity budgets;

• Control strategy including emission 

reduction commitments with adoption and 

implementation dates

NOTICE IS FURTHER GIVEN that due to a 

recent court decision, approval of the 24-hour 

PM2.5 portion of the 2012 AQMP is now subject 

to Clean Air Act (CAA) Subpart 4 requirements 

that provide for attainment by 2015, one year later 

than the attainment year in the 2012 AQMP. The 

CAA Subpart 4 Section 189(e) necessitates that 

control requirements applicable for major PM2.5 

sources shall also apply to major sources of 

PM2.5 precursors.

NOTICE IS FURTHER GIVEN that the 

aforementioned public hearings will address the 

following elements included in the Supplement:
P U B L I C A D V I S O R B U L L E T I N

• Attainment demonstration of the 24-hour 

PM2.5 NAAQS by 2015;

• Discussion of the effects from the drought on 

the attainment date;

• New transportation conformity budgets for 

2015;

• Updated RACT analysis;

• Updated list of control strategy commitments;

• Demonstration of compliance with CAA 

Subpart 4, Section 189(e) that applies to 

PM2.5 precursors, such as volatile organic 

compounds (VOC) and ammonia.

NOTICE IS FURTHER GIVEN that because the 

Supplement is not proposing to add new or delete 

any control measures that have the potential to 

have a direct or indirect adverse impact on the 

environment but merely presents updated analyses 

and other changes that do not have the potential to 

cause a direct or indirect adverse impact on the 

environment, the project is exempt under the 

requirements of the California Environmental Act 

(CEQA).

NOTICE IS FURTHER GIVEN that the 

Supplement and all supporting documents are 

available and may be obtained from the District’s 

Public Information Center or from:
