Air Pollution Control; Nonroad Vehicle

and Equipment Emission Inventories

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Notice of Public Workshop.

SUMMARY: The Environmental Protection

Agency is in the process of developing

a nonroad mobile source emissions

inventory model (the NONROAD

model). This notice announces a public

workshop for the purpose of discussing

the various issues involved in creating

a model for this diverse collection of

vehicles and equipment that comprise

the nonroad mobile source sector, and

provides a formal opportunity for

comment and reaction to the release of

the draft NONROAD model and its

associated technical documentation.

This notice also announces a hands-on

demonstration of the model

immediately following the public

workshop.

DATES: The workshop will be held

Thursday, June 25, 1997. The times are

from 8:30 am to 4 pm. A demonstration

of the NONROAD model will be held on

the same day from approximately 4:30

pm to 5:30 pm. All times are Central

Daylight Time.

ADDRESSES: The workshop will be held

in the Metcalf Federal Building, 17 West

Jackson Blvd., Chicago, IL, Lake

Michigan and Lake Ontario Rooms—

12th Floor, Great Lakes Conference and

Training Center. The Metcalf building is

located in the heart of the downtown

area. The model demonstration will be

held at the same location. Directions to

the workshop and model demonstration

can be obtained through the EPA OMS

World Wide Web (WWW) site, or

otherwise requested from the EPA

contact person. Information on how to

electronically access the web site or on

the EPA contact person appears

immediately below.

SUPPLEMENTARY INFORMATION:

Background

Nonroad mobile sources are a

significant source of air pollutants in

many areas of the United States. This

broad category is comprised of a diverse

collection of vehicles and equipment,

including vehicles and equipment in the

following nine categories:

—Recreational vehicles, such as allterrain vehicles and off-road

motorcycles;

—Logging equipment, such as chain

saws;

—Agricultural equipment, such as

tractors;

—Construction equipment, such as

graders and back hoes;

—Industrial equipment, such as fork

lifts and sweepers;

—Residential and commercial lawn and

garden equipment, such as leaf and

snow blowers;

—Recreational and commercial marine

vessels, such as power boats and oil

tankers;

—Locomotive equipment, such as train

engines; and

—Aircraft, such as jets and prop planes.

Current nonroad inventory

development practices are based on

EPA’s Nonroad Engine and Vehicle

Emissions Study (NEVES), done under

the 1990 Clean Air Act Amendment

requirements, and ‘‘Procedures for

Emission Inventory Preparation,

Volume IV: Mobile Sources’’ (EPA–450/

4–81–026d (revised), 1992). In

consideration of the increased

recognition of the importance of

emissions from nonroad sources in

terms of overall emissions and air

quality, and the considerable practical

difficulty of implementing the current

guidance, EPA is developing a nonroad

emissions inventory model (NONROAD)

to meet the needs of the modeling

audience.

NONROAD Emission Inventory Model

EPA has completed a draft version of

NONROAD, an accompanying detailed

user’s guide, and a number of technical

reports describing the model’s data

inputs and assumptions. This version of

the model covers all nonroad vehicle

and equipment types, except aircraft,

locomotives, and commercial marine.

The Agency will develop modeling

modules for aircraft and locomotives

sometime in the future. As for

commercial marine, a module for this

source category is under construction

and will be released for public review

later this year.

The draft model is intended to easily

create and project accurate,

reproducible inventories of nonroad

emissions. It has a number of uses, but

should be especially important to state

and local pollution control agencies in

satisfying the State Implementation Plan

(SIP) requirements of the Clean Air Act

Amendments of 1990.

Structurally, the model is made up of

three specific components: a graphical

user interface (GUI) which allows the

user to easily input model parameters,
30222 Federal Register / Vol. 63, No. 106 /Wednesday, June 3, 1998 / Notices

the core model which contains all

computational algorithms, and a

reporting utility for viewing and

summarizing modeled emissions

estimates. The model has been designed

to allow the user a high degree of

flexibility. As such, the model will:

—Calculate and report emissions in

total for the United States, and for

individual states and counties;

—Calculate emissions for a variety of

time periods (e.g., an entire year, any

particular month, any combination of

months, or daily weekday or weekend

day);

—Report emissions of six pollutants:

hydrocarbons (HC), carbon monoxide

(CO), NOX, sulfur oxides (SOX ), and

PM. The model will report both

exhaust and non-exhaust HC

emissions, the latter of which

includes crankcase, diurnal, refueling,

etc;

—Estimate current and future year

emissions in a specified geographic

area. In estimating future year

emissions, the model includes growth

and scrappage and can accommodate

a variety of control program options;

and

—View model results in different

formats such as an Emission PreProcessor System 2 (EPS–2) input file,

spreadsheet, and preformatted

reports.

The public workshop being

announced today provides a valuable

opportunity for EPA to receive

assistance in developing the final

NONROAD model through review and

comment by all interested users. The

workshop will focus on all aspects of

the model including user convenience,

data inputs and modeling assumptions,

computational structure, and reporting

options and formats. Presentations on

each subject will be followed by a short

discussion/question and answer period,

and there should be some time left at

the end of the day for more general open

discussion of the material that has been

presented. A detailed draft agenda for

the workshop will be posted on the EPA

OMS web site or may be obtained from

the EPA contact person (see FOR

FURTHER INFORMATION CONTACT).

Availability of Technical Reports and

NONROAD

EPA anticipates the workshop will be

highly interactive. To facilitate this goal,

all participants are encouraged to

review the draft technical reports on

data inputs and assumptions, as well as

the draft NONROAD model and

accompanying user’s guide. These

documents and the model are posted on

the EPA OMS web site or are otherwise

available on CD ROM from the EPA

contact person (see FOR FURTHER

INFORMATION CONTACT). Please visit this

site often to check for additional

information or model documentation

which may be posted between now and

the workshop date.

Comment Period

The Agency is providing a 60-day

public comment period on the draft

model and associated documents. This

period should be adequate for interested

parties to thoroughly review the

available information, and is consistent

with the guidelines for public review of

EPA emission models the Mobile

Sources Technical Review

Subcommittee of the Clean Air Act

Advisory Committee established under

the Federal Advisory Committee Act.

The comment period will be initiated at

the time the draft NONROAD model is

posted on the EPA OMS web site, which

EPA projects to be on or around June 15,

1998.

Model Demonstration

The Agency will hold a hands-on

demonstration of the model on the same

day, at the same location immediately

after the public workshop. The facility

is capable of seating approximately 20

people at individual personal

computers. This demonstration will be

held on a first come, first serve basis.

Please contact EPA via the NONROAD

E-mail box or the EPA contact person

(see FOR FURTHER INFORMATION CONTACT).

Additional Information

To the extent possible, EPA will post

material at the EPA OMS web site, as

described under FOR FURTHER

INFORMATION CONTACT, in advance of the

workshop. Those planning to attend,

and those interested in following the

progress of workshop planning more

closely, should periodically visit the

EPA OMS web site.
