## PREFACE

This document is to support EPA's evaluation of the 2 0 09 projecti on modeling inventories and inventory

attainment demonstration included in New Jersey’s PM2.5 State Implementation Plan (SIP) for t he Southern

New Jersey ( SNJ ) portion of the PM2.5 nonattainment area

. The SNJ area consists of the following counties:

Burli ngton, Camden, Cumberland, Gloucester, Mercer and Salem. The intended effect of this action is to

evaluate inventory components required by the Clean Air Act ( CAA ) which result in emission reductions that

will help contribute to attainment of the National Ambient Air Quality Standard for PM2.5 . This document

contains a detailed review of the New Jersey ’s submittal. Among the topics discussed below are: background

, criteria for approval and EPA ’ s final recommendation.



## BACKGROUND

Emission Inventory Requ irements and Inventory Attainment Demonstration

States are required under the Section 172 (c) of the CAA to develop emissions inventories of point, area, and

mobile sources for their attainment demonstrations. These inventories provide a detailed account ing of all

emissions and emissions sources by precursor or pollutant. In addition, inventories are used to model air quality

to demonstrate that attainment of the NAAQS can be met by the deadline, which

, in this case

, is for the 1997

PM2.5 NAAQS. Emission s reporting requirements for PM2.5 are given in the EPA published document

Emissions Inventory Guidance for Implementation of Ozone and Particulate Matter NAAQS and Regional Haze

Regulations , (EPA

– 454/R

– 99

– 006). This guidance was updated in November 2005 ( EPA

– 454/R

– 05

– 001).

In accordance with November 2005 guidance, the PM2.5 implementation rule required states to submit

inventory information on directly emitted PM2.5 and PM2.5 precursors and any additional inventory

information needed to support an attainm ent demonstration (where applicable).

Also i n accordance with Section 172 (c) of the CAA and with the PM2.5 implementation rule, the attainment

plan submitted by the State for the SNJ PM2.5 nonattainment area should include: 1) emission inventories for

t he plan’s base year (2002) and projection year (2009) and an attainment demonstration

, 2) The attainment

demonstration should include (a) technical analyses that locate, identify, and quantify sources of emissions

contributing to violations of the 1997 ann ual [and/or daily] PM2.5 NAAQS

, (b) analyses of future

- year

emissions reductions and air

- quality improvements expected to result from national and local air pollution

control programs

, and (c) adopted emission

- reduction measures with schedules for implemen tation.

The 2009 Projection Inventory and I nventory and 2009 Inventory Attainment Demonstration3 The State is required to include in the PM2.5 SIP 1) 2002 base year inventory, 2) 2009 projection inventories

and 3) a 2009 inventory attainment demonstrat ion. T he SIPs must demonstrate that the 2002 base year

inventory

, projected t o 20 09 with growth

, include control measures and rules that are adequate to provide for the

timely attainment in reducing emissions from pollutants the contribute PM2.5 nonattain ment in order to reach

20 09 attainment inventory emission levels.

There are general and specific components for an acceptable 20 09 projection inventor y and inventory attainment

demonstration . In general, the State must submit a revision to its SIP and t he aforementioned components must

meet certain minimum requirements for reporting by source category. Specifically, the source requirements are

detailed below.

A review process is used to determine that all components of the projection inventories and in ventory

attainment demonstration are present. The review also evaluates the level of supporting documentation

provided by the State and assesses whether the emissions were developed according to current EPA or

acceptable alternative guidance.



## CRITERIA F OR APPROVAL

Projection and Inventory Attainment Demonstration

There are several points that the projection inventories and i nventory attainment demonstration must adequately

address. For the projection inventories and inventory attainment demonstration to be acceptable they must pass

the following acceptance criteria:

1. W ere the 20 09 projection inventories developed in accordance with the procedures outlined EPA’s

latest guidance 1,3,4,6,7 ?

2. Were the Plans developed in accordance with EPA’s latest guid ance for Growth Factors,

Projections, and Control Strategies for R easonable Progress Goal Plans 1,3,4,6,7 ?

DETAILED ACTION AND EVALUATION

### Section 1: 2002 BASE YEAR INVENTORY

Calculation of 2002 Base Year Emission Inventory

The reader is referred to Region 2’s document entitled New Jersey State 2002 Base Year Inventory SIP

Technical Support Documentation for details on the approval of New Jersey ’s 2002 base year inventory

. EPA

proposed to approve New Jersey’s 2002 Base Year inventories on May 9, 2006, (71 FR 26895) and approved

the emission inventories on July 10, 2006 (71 FR 38770) . The reader is referred to these rulemakings for

additional information concerning the emission inventories and EPA’s approval.

## Section 2: Calculation of 2009 Projection Year Emission Inventories

A projection of 2002 PM2.5, NOx, and SO 2 anthropogenic emissions to 20 09 is required to determine the

emission reductions needed for inventory attainment demonstratio n

. The 20 09 projection year emission

inventories are calculated by multiplying the 2002 base year inventory by factors which estimate growth from

2002 to 20 09 . A specific growth factor for each source type in the inventory is required since sources typ ically

grow at different rates.

Projection Methodology

Major Point Sources

Electric Generat ing Unit s (EGU)

For the major point source category, the projected emissions inventories were first calculated by est imating

growth in each source category. As appropriate

, the 2002 emissions inventory was used as the base for applying

factors to account for inventory growth. The point source inventory was grow n from the 200 2 inventory to 20 09

for each facility using g rowth factors utilized in IPM model to forecast growth based on the following

variables/factors : electric demand ; natural gas, oil and coal supply forecasts; pollution control and performance ;

capacity cost and performance

, and replacement of older less ef ficient and polluting power plants with newer

more efficient units to meet future growth and state b y sta t e NOx and SOx caps.

Maintenance of the Fine Particulate PM2.5 NAAQS , dated March 24, 2010

. This document provides further

details and references on how projections were performed.

Non

- Electric Generating Units ( Non

- EGU s )

For the major point source category, the projected emissions inventories wer e first calculated by estimating

growth in each source category. As appropriate, the 2002 emissions inventory was used as the base for applying

factors to account for inventory growth. The point source inventory was grown from the 2002 inventory to 20 09

for each facility based on source classification codes using growth factors generated from EPA’s Economic

Growth Analysis System (EGAS) version 5 .0

, United States Department of Energy’s (USDOE) Annual Energy

Outlook Projections (AEO) 2005, state supplied p opulation and empl o yment data, where appropriate.

Since these methodologies and gro wth indicators are some of the preferred growth indicators to use as outlined

in EPA Guidance, 1,3,4,6,7 EPA finds New Jersey ’s methodology for projecting point sources to be

acceptable.

Area Sources

For the area source category, New Jersey projected emi ssions from 2002 to 2009 using growth factors generated

from USDOE AEO 200 7 , state supplied population and employment data, where appropriate.

This is in accordance with EPA ’ s recommended growth indicators for projecting emissions for area source

catego ries as outlined in EPA Guidance. 1,3,4,6,7

Since these methodologies and growth i ndicators are some of the preferred growth indicators to use as outlined

in EPA Guidance, 1,3,4,6, 7 EPA finds New Jersey ’s methodology for projecting area sources to be

acceptable.

Non

- Road Mobile Sources

Non

- road vehicle equipment emissions wer e projected from 2002 to 20 09 using the EPA’s National Mobile

Inventory Model (NMIM) 2 005 . N MIM 2005 contains growth factors, which are based on the historical trends

in nonroad equipment activity. This model was use to calculate past and future emission inventories for all

nonroad equipment categories except commercial marine vessels, locomotives and aircrafts. Emissions were

determined on a monthly basis and combined to provide annual emission estimates

.

Aircrafts , Locomotives and Commercial Marine Ves sels (CMV)

Aircraft , l ocomotives and CMV emissions were projected based on combined growth and control factors from

USEPA Clean Air Interstate Rule ( CAIR ) by determining the level of emissions and their associated ratios

between 2002 base and 2025 project ion year. From this point, the State determin e d the ratio of emissions

between 2002 and 2009 projection year using linear interpolation. The ratio s between 2002 and 2009 were7 determined and then multiplied by the 2002 base year to determine 2009 projecti on year emissions.

The reader is referred to Section 5.2.2.2.2 of NJDEP SIP Revision for the Attainment and Maintenance of the

Fine Particulate PM2.5 NAAQS , dated March , 2010 010 and Development of Emissions Projections for 2009,

. Th ese document s provide further details and references on how projections were

performed.

Since these methodologies and growth indicators are some of the pr eferred growth indicators to use as outlined

in EPA Guidance, 1,3,4,6, 7 EPA finds New Jersey ’s methodology for projecting non

- road mobile sources to

be acceptable.

Onroad Mobile Sources

For the onroad mobile source category, the primary indicator and to ol for developing on

- road mobile growth

and expected emissions are vehicle miles traveled (VMT) and US EPA ’ s mobile emissions model Mobile 6.2.03

(Mobile6 .2 ) . The 20 09 pollutant emission factors were generated by Mobile 6 .2 (with the associated controlled

measures applied

, w h ere appropriate) and applied to the monthly V MT projections provided by the State

. Month l y emissions were then combined to develop annual emission estimates.
