## DD. Many of the miscellaneous requirements of Section 110(a)(2)(A)-(M) of the Clean Air Act (CAA) relevant to the 1997 fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS) are already contained in the current 

## SIP'. The following table summarizes where the requirements of Section 11O(a)(2)(A)-(M) are addressed. Provisions of the current SIP referenced below, and where they are codified, may be viewed in the attached copies of the regulatory and statutory elements of Nevada's SIP (Enclosures 2 and 

## 3, respectively).



# ' The Nevada Division of Environmental Protection (NDEP) notes that many of the current 

### SIP regulatory provisions are seriously outdated and do not correspond to current State regulations. In February 2005, NDEP submitted a major SIP update with a revision in January 2006 and several supplemental submissions thereafter in response to EPA comments. EPA has acted on a potion of these submittals, but has proposed to disapprove the majority of Nevada's permitting program regulations update (72 FR 19144, April 17,2007). In the Technical Support Document for their proposed disapproval, EPA observes that most of Nevada's updated regulations are approvable, but based on their decision that the majority of the regulations comprising Nevada's permitting program are not separable, EPA is proposing to disapprove almost the entire permitting program update. Of 94 permitting regulations submitted, EPA found 

### 87 to be nonseparable. Of these 

### 87, EPA found that 

### 7 1 were actually approvable as submitted (although EPA did make minor comments on 10 of these). For the remaining 16regulations, Nevada submitted evidence (August 17,2007)showing that EPA's issues had been or were being addressed for 9 of them. NDEP further argued that the last 

### 7 provisions were approvable as 

### submitted. As of the date of this PM2.3SIP 

### submittal, EPA has not made a final determination regarding the update of Nevada's SIP permitting provisions. NDEP contends that although the current Nevada applicable SIP satisfies all of the basiclinfiastructure requirements 

### of CAA 

### 110(a)(2), Nevada's PM2.3SIP would better address the CAA 

### requirements ifNDEP's permitting program update was approved. NDEP once again urges EPA to approve Nevada's permitting provisions update. 

## 1 Section 11 0(a) element
31lO(a)(2)(A) Summary of element from EPA's October 2,2007 guidance
Section 110(a)(2)(A)requires SIPS to include enforceable emission limits and other control measures, means or techniques, schedules for compliance and otherrelated matters. €PA notes that the specific nonattainment area plan requirements of section 110(a)(2)(1) are subject to the timing requirement of section 172, not the timing requirement of section 110(a)(l),and also that SIPSto meet this section are not covered by the Consent Decree. 

### Provisions in the current Nevada SIP

The SIP includes enforceable emission limits and other control measures, means or techniques, schedules for compliance and other related matters in Nevada Administrative Code (NAC) 4458.22017,4458.2202,4458.22027,445.729,445.730,4458.2203, 

### 4458.22033, 4458.22037, Article 7.2.5.1, 4458.22043,4458.22047,4456.2205, 4458.22067,4458. 2207, Article 16.3.3.2,Article 16.3.3.3,4458.808,4458.816, 4458.2209, 4458.22097, and the Article 13'General Provisions for the Review of New Sources." Under EPA's transition policy, PMlomay properly be used asa surrogate for PM2.5in meeting NSR requirements.

### element 511O(a)(2)(B)

Section 1lO(a) ~ctober 2,2007 guidance Section 110(a)(2)(B)requires SIPSto include provisions to provide for establishment and operation of ambient air quality monitors, collecting and analyzing ambient air quality data, and making these data available to EPA upon request. 

### Summary of element from EPA's

Section 11O(a)(2)(C)requires States to include a program providing for enforcement of all SIP measures and the regulation of construction ofnew or modified stationary sources to meet prevention of significant deterioration (PSD) and nonattainment new source review (NSR) requirements. Section 110(a)(2)(D)requires SIPSto include provisions prohibiting any source or other type of emissions activityin one State from contributing significantly to nonattainment, or interfering with maintenance, of the NAAQS in another State, or from interfering with measures required to prevent significant deterioration of air quality or to protect visibility in another State. Section 11O(a)(2)(E)requires States to provide for adequate personnel, funding, and legal authority under State law to carry out its SIP, and related issues.

Section 11O(a)(2)(F)requires States to establish a system to monitor emissions from stationary sources and to submitperiodic emissions reports. Section 11O(a)(2)(G)requires States to provide for authority to address activities causing imminent and substantial endangerment to public health, including contingency plans to implement the 

### Provisions in the current Nevada SIP NDEP operates an air quality monitoring network that collects ambient air quality data that are compiled, analyzed and reported to EPA. The network comprises federally-approved monitors that measure ozone, carbon monoxide and PMlo. Under EPA's transition policy, PMlo may properly be used as a surrogate for PM2.5in meeting NSR requirements. Furthermore, NDEP commits to an ambient air quality monitoring program in its CAA section 105grant work plan. Complianceand enforcementmeasures are contained in NAC 445.663, 445.664,445.665, 445.667, 445.682,445.694, 445.696, 445.697, Article 2.5.4, Article 2.16.1,Article 2.1 6.1.1

### - 4 and Article 2.16.2.5. NDEP was given full delegation of the federal PSD program at 40 CFR 52.21 on October 19,2004 (see

## 9 1lO(a)(Z)(J); PSDNisibility, below). Nonattainment NSR provisions are found in Article 13 'General Provisions for the Review of New Sources" in the current SIP.

On July 31, 2007, EPA's approval of Nevada's interstate transport SIP (CAA 1lO(a)(Z)(D)(i)) for the 8-hour ozone and PM2.5 NAAQS promulgated in July 1997was published in the Federal Register (72 FR 41629). Also, Article 13 of the SIP, "General Provisions for the Review of New Sources," requires an environmental evaluation before a registration certificate may be issued. Finally, NDEP has full delegation of the federal PSD program, including NSR reform provisions (see

## 9 1lO(a)(Z)(J); PSDNisibility, below).

-
pppppp The legal authority for carrying out the Nevada SIP is contained in the Nevada Revised Statutes (NRS)that have been approved into the SIP; the specific statutes that deal with funding to support SIP requirements include NRS 4458.230,4458.235 and 4458.300. The Nevada Legislature approves BAQPIBAPC's funding and personnel resources every two years. BAQPIBAPC receives funding from fees paid by regulated businesses, motor vehicle registration fees and federal grants. The State Fiscal Year 2008 budget totaled about $6.59 million with about 50 approved full-time equivalentstaff positions. The2009 budget is about $6.81 million.
Nevada's current SIP provides a system for monitoring emissions from stationary sources and the submittal of periodic emission reports in NAC 4458.256 to 4458.265 and 4458.267.
Emergency powers are provided in Nevada's current SIP in NRS 4458.560, NAC 445.665 and NAC 4458.230.0
