### Introduction and Background

Sections 110(a)(1) and (2) of the federal Clean Air Act (CAA ), 42 U.S.C. § 7410(a)(1) and (2) hereafter

referred to as the “Infrastructure” State Implementation Plan (I

- SIP) requirements, requires states and

delegated local agencies to submit an implementation plan to the U. S. Environmental Protection Agency

(EPA) demonstrating their ability and authority to implement, maintain, and enforce each National Ambient

Air Quality Standard (NAAQS).

Section 110(a)(1) addresses the submittal re quirement s fo r I

- SIP s which are due to EPA not later than 3 years

after promulgation of a new or revised NAAQS. An I

- SIP needs to be submitted regardless of whether or not

a jurisdiction has any nonattainment areas.

This SIP revision submittal addresses Clark County’s authority to imple ment, maintain and enforce the 2008

Lead (Pb) NAAQS within the County’s jurisdiction.

Section 110(a)(2) lists the required elements that cover the I

- SIP. These elements include: enforceable

emission limitations, air quality modeling, enforcement programs , ambient air monitoring programs, and

confirmation of adequate personnel, resources and legal authorities. The following elements are addressed

- (M) Requirements for the Clark County Infrastructure State Implementation Plan for Pb

Element

(A) Emission limits and other control measures :

Requires State Implementation Plans (SIP) to include enforceable emission limits and other control measures, means,

or techniques, and schedules for compliance.

The Clark County Board of County Commissioners (BCC), in accordance with NRS Chapte r 445 B

, has adopted the Clark County

Air Quality Regulations (AQR) and has delegated enforcement authority to DAQEM

. Emission sources within Clark County are

required to comply with all existing rules and regulations through federally enforceable state imp lementation plan regulations 2

.

Clark County has a SIP Approved PSD program and most of the AQRs are SIP approved. Several AQR updates have been adopted

by the BCC and submitted to EPA for incorporation in the SIP (submittal dates in parentheses). A comp lete index of all AQRs (SIP

approved and local

- only) is included in Attachment B.

The following is a list of rules that have been revised and submitted for incorporation into the SIP:

**•** Section 0

- Definitions ( r evised as part of the Section 12.1 rulemaking and the Section 12.2 et al rulemaking);

**•** Section 12.0

- Applicability, General Requirements, Transition Procedures (adopted 11

- 09, submitted 02

- 10);

**•** Section 12.1

- Permit Requirements for Minor Sources (adopted 11

Several AQRs such as Section 12.9

– Annual Emissions Inventory Requirement, and Section 12.10

– Continuous Monitoring

Requirements for Stationary Sources, are local

- only rules.

Section 0 and Section 12.2 were revis ed in November, 2010 specifically for the purpose of meeting the Greenhouse Gas (GHG)

Tailoring Rule requirements, submitted as a SIP revision on January 4, 2011.

The significant level for lead in Sections 12.2, 12.3 and 12.4 is 0.6 tons/year.

Section 12.2 was revised in November 2010 to include provisions for GHG, the SIP revision was submitted January 4, 2011.

Other sections from the AQRs are not part of the SIP; therefore they are local

- only rules. They have been adopted by the BCC and

are enforce d by the Control Officer.State Implementation Plan Revision to Meet the Infrastructure SIP Requirements for LeadClark County March 20129Element(D)Interstate transport provisions:Requires SIPs to contain adequate provisions prohibiting emissions generatedwithin the state from contributingsignificantly to nonattainment in, or interfering with maintenance by, any otherstate with respect to the NAAQS, orfrom interfering with measures required to be includedin the SIP of any other state to prevent significantdeterioration or toprotect visibility.On July 31, 2007, EPA’s approval of Nevada’s interstate transportSIP (CAA 110(a)(2)(D)(i)) for the 8-hour ozone and PM2.5NAAQS promulgated in July 1997 was published inthe Federal Register(72 FR 41629).Additionally, PSD and NSR review provisionsin the subsections of Sections 12.2 -Permit Requirements for Major Sources inAttainment Areas, and 12.3 - Permit Requirements for Major Sourcesin Nonattainment Areas, of the AQR require an assessment ofvisibility impairment as partof the environmental review.According to EPA’s final guidance memo (released on October 17, 2011), the physical properties of Pb prevent Pb emissions fromexperiencing the same travel or formation phenomena as PM2.5or ozone. More specifically, there is a sharp decrease in Pbconcentrations, at least in the coarse fraction, as the distance from a Pb source increases. Pb sources contribute significantly to nonattainment or interfere with maintenance inneighboring states if: 1)the source has emissions of 0.5or more tons per year; and 2) islocated in close proximity to state borders (i.e., within 2 miles). DAQEMreviewed the lead emissions inventory and source dataandverified that no industrial facilityor other source in Clark County emits 0.5 or more tons per year.Furthermore, when evaluating the extent that Pb could impact visibility, EPA determined that Pb related visibility impacts werefound to be insignificant3.3Guidance on Infrastructure State Implementation Plan (SIP) ElementsRequired Under Section 110(a)(1) and 110(a)(2) for the 2008Lead (Pb) National Ambient Air QualityStandards (NAAQS), October 17, 2011 – page 9State Implementation Plan Revision to Meet the Infrastructure SIP Requirements for LeadClark County March 201210Element(E)Adequate resources:Requires SIPs to provide necessary assurances for adequatepersonnel, funding, and authority under state law to carryout its SIP, to contain requirements addressing potential conflicts of interest, and to provide necessary assurances thatthe state retains responsibility for ensuring adequate implementation of the SIP where the state relies on a local orregional government for implementation of any SIP provision.NRS 445B.500 authorizes Clark County to implement and administer air quality management programs within the geographicboundaries of Clark County. Theseprograms are managed through the DAQEM, witha current air quality budget of approximately$28.7 million, and 105 full-time equivalent staff positions. Primary sources of funding are:****Permits and technical services fees collected from regulated emission sources;****Federal grants;****State grants from the Nevada Air Pollution Control Account per NRS 445B.830;****RTC transportation tax revenue,as established by NRS 377A.090;****Federal Congestion Mitigation and Air Quality Program (CMAQ) funds.NRS 445B.520 gives the State Environmental Commission4the authority to supersede the county program.Clark County Code Chapter 2.42 – Ethical Standards - specifies conflict ofinterest requirements for Clark County public officers andofficials, including members of the BCC and the Control Officer.
