PUBLIC NOTICE: 

30-DAY NOTICE OF PUBLIC HEARING AND PUBLIC COMMENT PERIOD 

PROPOSED AMENDMENTS TO EXISTING CLARK COUNTY AIR QUALITY 

REGULATIONS SECTIONS 0, 12.0, 12.1, 12.2, 12.3, AND 12.4 AND THE 

PROPOSED REPEAL OF SECTION 1 

This public notice initiates a public comment period on proposed amendments to Sections 

0, 12.0, 12.1, 12.2, 12.3, and 12.4 and the repeal of Section 1 of the Clark County Air 

Quality Regulations. The public comment period will start February 2, 2014, and end at 

5:00 PM March 3, 2014. Its purpose is to give the public and regulated community an 

opportunity to review and provide comments and input on the proposed 

amendments/repeal. Written comments will be incorporated into the agenda documents 

submitted to the Board of County Commissioners as part of the public hearing. The 

Board will consider these proposed amendments at a public hearing at 10:00 AM March 

18, 2014, at the Commission Chambers, Clark County Government Center, 500 S. Grand 

Central Parkway, Las Vegas. 

The rules proposed for amendment address federal requirements for stationary sources of 

air pollution. On October 18, 2012, the U.S. EPA published a final rule in the Federal 

Register (77 FR 64039; EPA-R09-OAR-2012-0566). As a result of this rulemaking, the 

Clark County Air Quality Regulations that address the permitting requirements for both 

large and small stationary sources were partially approved and disapproved. The 

disapprovals set an 18-month time clock in motion to complete the revisions necessary to 

meet all federal requirements and be approved into the Nevada State Implementation Plan 

(SIP). Under the provisions of the federal Clean Air Act, failure to adequately address the 

disapproval issues within the 18 months specified in the Act will result in the application 

of the penalty sanctions of the Act, which include increases in permitting requirements 

and sanctions on the use of federal highway funds. Most of the disapproval issues that 

EPA found were the result of changes in federal law that occurred after the rules were 

submitted in 2010. The following Clark County Air Quality Regulations are proposed to 

be revised or repealed: 

Section 0: Definitions: Proposed revisions to meet federal requirements and clarify 

definitions in this section that are currently found in other sections of the AQRs. 

Section 1: Definitions: This section is obsolete and contains terms that are no longer 

used or are currently found in other AQRs. It is proposed that the Board repeal the rule 

and authorize its removal from the Nevada State Implementation Plan. 

Section 12.0: Applicability, General Requirements and Transition Procedures: 

Proposed revisions to meet federal requirements on compliance with the Nevada SIP; 

stack height limitations; and recordkeeping and reporting. 

Section 12.1: Permit Requirements for Minor Sources: Proposed revisions to address 

federal requirements regarding fine particulates (PM2.5), clarify references to National 
Ambient Air Quality Standards, and incorporate a list of insignificant activities not 

subject to review as an appendix. 

Section 12.2: Permit Requirements for Major Sources in Attainment Areas: 

Proposed revisions to update certain definitions and to add federal emission limits for 

PM2.5. 

Section 12.3: Permit Requirements for Major Sources in Nonattainment Areas: 

Proposed revisions to update certain definitions, provide federal language regarding 

requirements for PM2.5, and align offset requirements with federal law. 

Section 12.4: Authority to Construct Application and Permit Requirements for Part 

70 Sources: Proposed revisions to clarify federal requirements that establish levels of 

review, prohibit permit issuance when all applicable requirements will not be met, and 

require permit conditions that meet the applicable requirements of the Nevada SIP.
