A. A county that contains any part of area A, as defined in section 49-54 1, shal-I develop, 

implement and enforce in area A, as defined in section 49-54 1, an ordinance relating to residential wood burning 

restrictions, including a no burn restriction when monitoring or forecasting kdkates BY THE DEPARTMENT OF

EXCEEDED. 

B. ON OR BEFORE OCTOBER 3 1,2007, A COUNTY THAT CONTAINS ANY PART OF AREA A, AS DEFINED 

IN SECTION 49-541, SHALL AMEND THE ORDINANCE PRESCRIBED BY SUBSECTION A OF THIS 

SECTION TO INCLUDE A NO BURN RESTRICTION FOR ANY HIGH POLLUTION ADVISORY DAY

Potential Emission Reductions From No Burn Days -High Pollution Advisory Days (tonslyear) 1 Re ion 

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 to take 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 of nine percent of high pollution 

advisory days during this 100 day period was applied to the wood burning emissions (annual tons x 0.9 for the season x 

0.9 for fireplaces/stoves x 0.09 for the percentage of high pollution advisory days) to obtain the PMlo emission 

reduction.

Extension of Maricopa County No-Burn Days 

to Outdoor Fires 

Control Measure: Extension of Maricopa 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 1.2 million population to adopt an ordinance 

banning burning on forecasted "No Burn" days in wood burning chimineas and similar outdoor fires. 

Legislative language: 

ARS 549-501. Unlawful open burning; exceptions; fine; definition 

G 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, SUCH A COUNTY SHALL 

PROHIBIT BY ORDINANCE THE USE OW WOOD 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 forecast high pollution advisory, and all resorts would comply with the regulation and 

bum no wood. Standard emission factors and wood burned per hour were used to calculate the emission reductions in 

the above table, with the PM2 emission rate being 93% of the PMlo rate. 

Potential Emission 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 1 tons of PMlo emissions is based 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 half the 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 PM2.5 comprising 93% of the PMlo emissions, and on the nine 

high pollution advisory days, the net reduction, the sum of the resorts and the outdoor residential, is about 12 tons per 

year.

( Ban on Open Burning during Ozone Season 1 

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 1 through September 30 each year in Area A. 

Legislative Language: 

ARS 549-50 1. Unlawful open burning; exceptions; fme; defdtion 

A. Notwithstanding the provisions of any other section of this article: , 

1. It is unlawful for any person 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 BE IGNITED 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 of burning 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.
