Air Quality Management Division 

SUBJECT: Public Hearing: Proposed approval and adoption of the "State 

Implementation Plan to Meet the Lead Infrastructure SIP Requirements of 

Clean Air Act Section 11 0(a)(2)" 

Staff Recommendation 

Approve and adopt the "State Implementation Plan to Meet the Lead Infrastructure SIP 

Requirements of Clean Air Act Section 110(a)(2)". 

Background 

The U.S. Environmental Protection Agency (EPA) establishes health based national 

ambient air quality standards (NAAQS) for six criteria pollutants including lead. The 

Clean Air Act (CAA) directs states to address basic State Implementation Plan (SIP) 

requirements to implement, maintain, and enforce the NAAQS. Many of the CAA 

Section 110(a)(2) SIP elements relate to the general information and authorities that 

constitute the "infrastructure" of a state's air quality management program. States are 

required to submit an Infrastructure SIP (I-SIP) within three years after promulgation of 

a new or revised standard. 

In October 2008, EPA substantially strengthened the lead NAAQS by revising the level 

of the primary (health-based) standard from 1.5 micrograms per cubic meter «(.Ig/m3

) to 

0.15 (.Ig/m3

• The rule also requires source oriented ambient air monitoring for nonairport lead point sources emitting 1.0 tons per year, and airport point sources emitting 

0.5 tons per years. Currently, there are no sources within Washoe County that meet 

those criteria. 

This I-SIP is a summary of current air quality management elements in Washoe 

County's portion of the Nevada lead SIP. It includes air quality regulations and 

programs demonstrating the Health District's ability to meet these CAA requirements. 

The I-SIP was prepared in coordination with the: 

P.O. BOX 11130 Reno, NV 89520-0027· (775) 784-7200 • FAX (775) 784-7225

report. The document is 24 pages and can be accessed from the "News & Events" 

section of the Air Quality Management Division website,

Mr. Daniel Inouye of AQM at (775) 784-7214 or dinouye@washoecounty.us. 

If the I-SIP is approved and adopted, it will be submitted to EPA through the Nevada 

Division of Environmental Protection as a revision to the Washoe County portion of the 

Nevada Lead SIP. 

A notice of today's public hearing was published in the Reno Gazette-Journal on July 

22, August 10, and August 22, 2011. The I-SIP has been available for public inspection 

at the AQMD website and office since July 21, 2011. 

Recommended Motion 

Move to approve and adopt the "Washoe County Infrastructure SIP for the 2008 Lead 

NAAQS" and direct Staff to forward it to EPA as an amendment to the Washoe County 

portion of the Nevada Lead State Implementation Plan. 

Alternatives 

The District Board of Health may: 

1. Elect not to adopt the I-SIP; or 

2. Continue this public hearing and direct Staff to research some portion of the 1-

SIP and report back to the Board at a future meeting.
