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 peri od will start February 2, 2014, and end at 5:00 PM March 3, 2014. Its purpose is to gi ve the public and regu lated community an opportunity to review and provide co mments and input on the proposed amendments/repeal. Written comments will be incorporated into the agenda documents submitted to the Board of County Commission ers as part of the public hearing.

The rules proposed for amendment address fede ral requirements for st ationary 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 tim e 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 specifi ed 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 f unds. Most of the disa pproval issues that EPA found were the result of changes in fede ral law that occurred after the rules were submitted in 2010. The following Clark County Ai r Quality Regulations are proposed to be revised or repealed:

Section 0: Definitions: Proposed revisions to meet fe deral requirements and clarify

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

Section 1: Definitions: This section is obsolete and c ontains terms that are no longer used or are currently found in other AQRs. It is proposed that the Bo ard 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 requirem ents 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 regard ing fine particulates (PM 2.5 ), clarify references to NationalAmbient Air Quality Standards, and incorp orate 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 defini tions and to add fede ral emission limits for

PM 2.5

.

Section 12.3: Permit Requirements for Major Sources in Nonattainment Areas: Proposed revisions to update certain definitions, provide federal language regarding requirements for PM 2.5 , and align offset requirem ents with federal law.

Section 12.4: Authority to Construct App lication and Permit Requirements for Part

70 Sources: Proposed revisions to clarify federal re quirements that es tablish levels of review, prohibit permit issuance when all appl icable requirements will not be met, and require permit conditions that meet the applicable requirements of the Nevada SIP.
