TO: District Board of Health FROM: Kevin Dick, Director 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 AirAct Section 110(a)(2)"

StaffRecommendation Approve and adopt the "State Implementation Plan to Meet the Lead Infrastructure SIP Requirements ofClean AirAct 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 newor 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

### 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:
