Emissions Benefit Calculation Method: The Maricopa County Emissions Inventory provides "residential wood burning" emissions estimates for PMlo,PM2.5, and NO,. Ninety percent of this burning was assumed totake place in the 100 days of late fall and winter, and 90% of the burning was assumed to take place in fireplaces and woodstoves. The average ofnine percent ofhigh pollution advisory days duringthis 100day period was applied to the wood burning emissions (annual tons x 0.9 forthe season x 0.9 for fireplaces/stoves x 0.09 for the percentage of high pollution advisory days) to obtain the PMloemission reduction.

### ControlMeasure: Extension ofMaricopa County No-Burn Days to Outdoor Fires Target pollutants: PMlo, PM2.5, NO,, VOC, CO Description: This measure requires a County in Area A with over 1.2million population to adopt an ordinance banning burning on forecasted "No Burn" days in wood burning chimineas and similar outdoor fires.

### F. Nothing in this section is intended to permit any practice which is a violation of any statute, ordinance, rule or regulation in a county with a population in excess of one million two hundred thousand persons according to the most recent united States decennial census. NOTWITHSTANDING ANY OTHER LAW, SUCHA COUNTY SHALL PROHIBIT BY ORDINANCE THE USE OWWOOD BURNING CHIMINEAS, OUTDOOR FIRE PITS 

### AND SIMILAR OUTDOOR FIRES ON THOSE DAYS FOR WHICH THE COUNTY HAS ISSUED A NO BURN DAY RESTRICTION.
Emission Benefits:

Emission Benefits Calculation Method: These emission reductions were calculated for both resorts and residential. For the resorts, (1) assume 30 large resort hotels in Area A, (2) 

### Each resort hotel is likely to have one or more chimineas and one large decorative fire pit, and (3) Chimineas or large fire pits are in operation for six hours during late fall or winter evenings. During these seasons there would be nine days with a forecasthigh pollution advisory, and allresorts would comply with the regulation and bum no wood. Standard emission factors and wood burned per hour were used to calculatethe emission reductions in the above table, with the PM2 emission rate being 93% ofthe PMlo rate. PotentialEmission Reductions from Ban Operation of Chimineas on No Burn Days (tonslyear)

For residential outdoor wood burning of every kind (barbeques, fire pits, chimineas, above-ground fire boxes), the Maricopa County Inventory (2005) estimate of 23 1tons ofPMlo emissions isbased only on indoor burning (mostly fireplaces and wood stoves). Outdoor burning during the 100 late fall and winter days, during which most high pollution advisories are called, is assumed to be one halfthe indoor burning. For most residences, the outside wood use would be less than inside because either a fire is not set because it's too cold, or it is set in a chirninea, which bums much less wood than a fireplace. Based on the county estimate, on PM2.5comprising 93% ofthe PMloemissions, and on the nine high pollution advisory days, the net reduction, the sum ofthe resorts and the outdoor residential, is about 12 tons per year.

Control Measure: Ban on Open Burning during Ozone Season Target pollutants: PMlo, PMz.5, NOx,VOC Description: This control measure prohibits open burning during May 1through September 30 each year in Area A. Legislative Language: ARS 549-501. Unlawful open burning; exceptions; fme; defdtion A. Notwithstanding the provisions of any other section of this article: 

### , 1. It is unlawful for anyperson to ignite, cause to be ignited, permit to be ignited, or suffer, allow, or maintain any open outdoor f~e except as provided 

### in this section. 

### 2. FROM MAY 1 THROUGH SEPTEMBER 30 EACH YEAR, IT IS UNLAWFUL FOR ANY PERSON TO IGNITE, CAUSE TO BE IGNITED, PERMIT TO BEIGNITED OR SUFFER, ALLOW OR MAINTAIN ANY OPEN OUTDOOR FTFE IN AREA A AS DEFINED IN SECTION 49-54 1.

Emissions Benefits:

Emissions Benefit Calculation Method: This type ofburning tends to conducted by farmers and land clearers and occurs most in a summer and winter season. The annual emissions from the Maricopa County Emissions Inventory were divided 

### in two and the summer emissions were zeroed out, reducing the emissions in this category by one half. Potential Emission Reductions from Ban on Open Burning (tonstyear) Region Area A PMlo 13 PM2.s 13 NOx 4 VOC 8 CO
