# 2011 Periodic Emissions Inventory for Ozone Precursors

ADDENDUM

August 2015



## 1. Background and Introduction

This a ddendum serves as a suppl ement to the 2011 Periodic Emissions Inventory for Ozone Precursors

for the Maricopa County , Arizona, Eight

- Hour Ozone Nonattainment Area , published in F ebruary

2014, and included as part of the MAG 2014 Eight

- Hour Ozone Plan

– Submittal of Marginal Area

Requirements for the Maricopa Nonattainment Area submitted to EPA in J une 2014. Th is docume nt

has been developed by the Maricopa County Air Quality Department (MCAQD) for two purposes :

• It add s a facility to the list of available Emi ssion Reduction Credits (ERC s) in the Arizona

Emissions Bank.

• In response to inquiries from EPA staff, it provides a “recasting ” of the emissions calculations to

develop an ozone season

- day inventory reflecting the June

– August 2011 period (vs. July

– September addressed in the original Periodic Emissions Inventory [ PEI ] report ).

Each of the above points is discussed in further detail below. Where applicable, the changes that affect

(annual and/or season

- day) emissions estimates for a particular source category are provided in

summary tables. This Addendum concludes with a detailed table summarizing emissions for the ei ght

hour ozone nonattainment area (NAA) , revised to reflect the two analyses described above.

Note that shaded cells in the tables below indicate emissions values that have been revised from the

original PEI report. Where applicable, t able and page numbe r s from the originally published 2011

Periodic Emissions Inventory document published in February 2014 are noted parenthetically in the

table caption s

.

. A vailability of A ddition al Emission Reduction Credits (ERCs)

Since the original publication of th e 2011 Periodic Emissions Inventory for Ozone Precursors in

February 2014, additional emissions reduction credits (ERCs) have been added to the Arizona

Emissions Bank. Penn Racquet Sports, a sports

- ball manufacturing facility located within the eight

h our ozone nonattainment area, closed permanently in 2009, and its ERCs have been added to the

Arizona Emissions Bank. Table A1 below lists the currently available emission reduction credits,

while Table A2 provides updated annual and ozone season

- day emissio ns estimates for the eight

- h our

ozone nonattainment area.

These newly available ERCs have also been incorporate d into the base

- year and future

- year emissions

inventories used by the Maricopa Association of Governments (MAG) for the modeling exercises

cond ucted in developing the moderate

- area ozone State Implementation Plan (SIP).

### 2011 Ozone Precursor Emissions Inventory 2 ADDENDUM : August 2015 T able A 1. Emission reduction credits as of December 31, 2011. (cf. original Table 2.5

Nonattainment Area

3 .1 Identifying an Alternative Time Period for the 2011 Ozone Season

For this exercise, MCAQD and MA G revisited the 2011 Periodic Emissions Inventory (PEI) originally

prepared in 2014, to investigate if there were any significant differences in ozone season

- day emissions

when considering an ozone season different from the July

– September period defined in the original

2011 PEI

. To identify an alternative period deemed more representative of the actual ozone season,

c al endar year 2011 data on average and maximum Air Quality Index (AQI) values , as well as

information on the incidence of ozone exceedances, were analyzed. The base data is shown below in

Table A3

.

Table A3. Average and maximum AQI v alues, and frequency of o zone e xceedances in 2011 , by month.

### 2011 Ozone Precursor Emissions Inventory 3 ADDENDUM : August 2015 From the above information , three

- month rolling averages were calculated for each parameter, in order

to identify the most representative three

- month period for the ozone season. Results are shown in

Table A 4; maximum values in each col umn are shown in bold.

### The above table indicates that the rolli ng three

- month average for each of the parameters analyzed

reaches its maximum value for the June through August time period. Thus

, this time period is

considered representative of the 2011 ozone season for the Phoenix area , and used in this “recasting”

e xercise to assess the impact of redefining the ozone season on overall emissions in the 2011 PEI.

3 .2 Recalculating the 2011 Ozone Season

- d ay Inventory

Each source category contained in the original 2011 ozone precursor emissions inventory was

reviewe d, and season

- day emissions re

- calculated where needed, depending on the methodology used

to derive the original e missions estimates for that source category. The derivation of the “ recast ”

emissions values for each source category type are described in mo re detail below

. At the end of this

section, Table A16 presents a comparison of season

- day emissions for each source category, including

the values contained in the original 2011 PEI report (for the July

– September period), as well as the

“recast” emission s reflecting the three

- month period covering June through August.

3 .2.1 Point and Area Sources

When analyzing season

- day emissions calculations f or the recasting exercise, each point and nonpoint

(area) source type could be classified into o ne of the fo llowing categories:

• Sources whose e missions were derived from actual activity data for the June

– August time

period; thus whose emissions remain unchanged. All reported point source activity f al l s into

this classification , as did those area source categor ies ( e.g., bakeries, graphic arts) which had

been estimated directly based on data from individual facility survey s , which were then

“grown” by overall employment for that sector

.

• Sources whose a ctivity (and thus e missions ) were assumed to be evenly distr ibuted

throughout the year , thus whose emissions remain unchanged . Examples include commercial

cooking and consumer solvent use.

• Some emission categories (e.g., residential combustion of wood, LPG, and kerosene ) were

assumed to have no summertime activity (at any time between May and September), thus

ozone season

- day emissions for these source categories remained zero.

### 2011 Ozone Precursor Emissions Inventory 4 ADDENDUM : August 2015 • Several source categories were estimated using published EPA guidance and recommended

"seasonal activity factors" to derive season

- day emi ssions from annual estimates; thus overall

emissions estimates remained the same.

• One category, prescribed fires, had no reported activity in either June or September, thus the

reported emissions for the ozone season (reflecting burns conducted in July an d August)

remained the same.

For the remaining categories, adjustment s were made to recalculate the ozone

- season emissions for the

June

– August period . For the following area source categories

, monthly data was used to estimate

season

- day emissions in bot h the original PEI report , as well as this Addendum:

• Agricultural pesticides

• Gas stations Stage I: Submerged fill

• Gas stations Stage I: Bal. submerged fill

• Underground tanks: Breathing/emptying

• Truck: gasoline (tank trucks in transit)

• Accidental releases

• W ildfires

3 .2.2 Nonroad Mobile Sources

3 .2.2.1 Source Categories Calculated Using the NONROAD Model

Annual and monthly emissions for nonroad mobile source categories except locomotives, aircraft,

airport ground support equipment (GSE) and auxiliary power unit s (APU), were developed using

NONROAD2008a for the 2011 PEI report

. For this Addendum, m onthly nonroad mobile source

emissions for June, July, and August 2011 were extracted from the NONROAD2008a outputs which

had been gener ated for the original 2011 PEI. Table A 5 below provides monthly emissions within the

eight

- hour ozone nonattainment area for each major nonroad source category calculated by the model

. Season

- day emissions were then calculated using activity allocation factors ( as described in Section 4.1

of the original 2011 Ozone Precursor PEI report ) . Lawn and garden e quipment total emissions we re

calculated by sum ming the residential and commercial lawn and garden equipment categories

. Season

day emissions for the period of June throug h August 2011 are provided in Table A 6

### 3 .2.2.2 Aircraft, Ground Support Equipme nt , and Aux iliary Power Units

Emissions from a ircraft, ground support equipment (GSE), and auxiliary power units (APU s ) for the

period of June through August 2011 we re calculated by applying adjustment factors to th e emission

estimates prepared for the o riginal 2011 PEI report, covering the period of July through September

2011 . The se adjustment factors for airports have been developed by dividing the number of operations

for the June

– August timeframe, by the number of operations within the July

– September period

covered by the initial model calculations, for each of four aircraft categories (air carrier, air taxi,

general aviation, and military). M o nthly airport operational data we re obtained from the Federal

Aviation Administration (FAA) Air Traffic Acti vity Data System (ATADS) database for the year

2011

, and from MAG 2009 airport survey data. The total operations for airports for the two periods

are presented in Table A 7

MOVES2010b was used to ge nerate monthly onroad mobile source emissions for vehicle classes,

facility types, weekdays and weekend for the 2011 Periodic Emissions Inventory (PEI) for ozone

precursors. Monthly onroad mobile source emissions in the eight

- hour ozone nonattainment area for

June through August were obtained from the MOVES2010b output database developed for the original

2011 PEI; results are shown in Table A 9 below . To calculate the average daily emissions for the

period , the thre e

### The two tables below summarize the changes in emissions that result from redefining the ozone season

as the June

– August time period. Table A14 presents the absolute emission changes ( both increases

and decreases), while Table A15 presents these changes in percentage terms. Both tables indicate that

the net change in anthropogenic emissions that results from a revised definition of an “ozone season”

to June

– August is insignificant ( i.e

. , slightly less than 1% of the overall inventory). Finally, Table A16

presents a detailed, line
