### I,1987 the United States Environmental Protection Agency (US EPA) set aNational Ambient 

### Air Quality Standard (federal standard)

### for particulate matter less than 10 microns 

### (PMl0) at 150 micrograms per cubic meter 

### for a24-hour period. V/HEREAS, in

### August 1987 the US EPA classified Mammoth Lakes as a Group 

### I area 

### with a greater thang5o/o 

### probability of exceeding the federal standard, and required the Great Basin 

### Unified

### Air Pollution Control 

### District (District) to develop a state implementation plan thatwould include acontrol strategy and regulatory requirements to bring the area into attainment 

### with the standard. WHEREAS, the 

### District and theTown of Mammoth Lakes (Town)

### jointly investigated the 

### PMl0 air quality problem in theTown and found that the federal 

### PMl0 standard was violated about eleven times per year, andthat the high 

### PMl0 levels were largely caused by particulate emissions from residentialwood combustion 

### (RWC) and road dust entrained into the air by vehicles on roads treated

### with volcanic cinders during thewinter. WHEREAS, in November 1990 the 

### District and Town

### jointly adopted the 1990

### fuel appliances, institutedvoluntary and mandatory no bum days 

### for fireplaces and woodstoves, required street sweeping to clean upthe cinders on the roads after snow events, and

### WHEREAS, ambient PM10 levels measured in the Town 

### from 1993 through 

### 20l2have demonstrated compliance 

### with the federal 

### PMl0 standard and the 

### District has committed to continue monitoring 

### for at least 20 years after the area is redesignated to attainment to demonstrate maintenance of the standard. 

### WHEREAS,future compliance in the Town 

### will be ensured 

### with the continued implementation of regulations for the installation and operation of 

### RWC devices and the continued use

### of street sweepers to remove volcanic cinders 

### from roadways after 

### winter storms'
