Air Quality Management Division 

Washoe County Health District 

P.O. Box 11130 

Reno, Nevada 89520-0027 

Dear Mr. Inouye: 

Thank you for your submission of the Washoe County Health District Air Quality Management 

Division (AQMD's) 2013 Ambient Air Monitoring Network Plan in July 2013. We have 

reviewed the submitted document based on the requirements set forth under 40 CFR 58. Based 

on the information provided in the plan, EPA approves all portions of the network plan except 

those specifically identified below. With this plan approval, we also formally approve the 

following system modification(s): relocation of the Galletti site to address adequate spacing from 

trees, and initiation of SLAMS PM2.s monitoring at the Sparks site. 

Please note that we cannot approve portions of the annual network plan for which the 

information in the plan is insufficient to judge whether the requirement has been met, or for 

which the information, as described, does not meet the requirements as specified in 40 CFR 

58.10 and the associated appendices. EPA Region 9 also cannot approve portions of the plan for 

which the EPA Administrator has not delegated approval authority to the regional offices. 

Accordingly, the first enclosure (A. Annual Monitoring Network Plan Items where EPA is Not 

Taking Action) provides a listing of specific items of your agency's annual monitoring network 

plan where EPA is not taking action. The second enclosure (B. Additional Items Requiring 

Attention) is a listing of additional items in the plan that EPA wishes to bring to your agency's 

attention. 

The third enclosure (C. Annual Monitoring Network Plan Checklist) is the checklist EPA used to 

review your plan for overall items that are required to be included in the annual network plan 

along with our assessment of whether the plan submitted by your agency addresses those 

requirements. 

The first two enclosures highlight a subset of the more extensive list of items reviewed in the 

third enclosure. All comments conveyed via this letter (and enclosures) should be addressed 

(through corrections within the plan, additional information being included, or discussion) in 

next year's annual monitoring network plan.

• EPA identified items in your agency's annual monitoring network plan where a 

requirement was not being met or information in the plan was insufficient to judge 

whether the requirement was being met based on 40 CFR 58.10 and the associated 

appendices. Therefore, we are not acting on the following items:

Additional information for each of these items may be found for the row listed in column 2, in 

the third enclosure (C. Annual Monitoring Network Plan Checklist). 
• [Item 38] AQMD uses the term ''Designated" (rather than ''Primary'') to differentiate 

between a "Collocated" monitor. It is recommended that the term ''Primary'' be adopted 

in place of"Designated." · 

• [Item 46] NCore required parameters reported (p.26-31) are considered a subset of the 

SLAMS network. Please also add SLAMS as a monitor type to the NCore parameters. 
C. ANNUAL MONITORING NETWORK PLAN CHECKLIST 

(Updated 11/26/2013) 

Year: 2013 

Agency: Washoe County Health District Air Quality Management Division (AQMD) 

40 CFR 58.1 O(a)(1) requires that each Annual Network Plan (ANP) include information regarding the following types of monitors: SLAMS 

monitoring stations including FRM, FEM, and ARM monitors that are part of SLAMS, NCore stations, STN stations, State speciation stations, SPM 

stations, and/or, in serious, severe and extreme ozone nonattainment areas, P AMS stations, and SPM monitoring stations. 

40 CFR 58.10(a)(l) further directs that, "The plan shall include a statement of purposes for each monitor and evidence that siting and operation of 

each monitor meets the requirements of appendices A, C, D, and E of this part, where applicable." On this basis, review of the ANPs is based on the 

requirements listed in 58.10 along with those in Appendices A, C, D, and E. 

EPA Region 9 will not take action to approve or disapprove any item for which Part 58 grants approval authority to the Administrator rather than the 

Regional Administrators, but we will do a check to see if the required information is included and correct. The items requiring approval by the 

Administrator are: P AMS, NCore, and Speciation (STN/CSN). 

Please note that this checklist summarizes many of the requirements of 40 CFR Part 58, but does not substitute for those requirements, nor do its 

contents provide a binding determination of compliance with those requirements. The checklist is subject to revision in the future and we welcome 

comments on its contents and structure. 

Key: 

White = meets the requirement. 

Yellow = requirement is not met, or information is insufficient to make a determination. Action requested in next year's plan or outside the ANP 

process. 

= item requires attention in order to improve next year's plan.
