Risk Management Guidance for the Permitting of
New Stationary Diesel-Fueled Engines
Risk Management Guidance for the Permitting of New Stationary Diesel-Fueled Engines:
The
Risk Management Guidance for the Permitting of New
Stationary Diesel-Fueled Engines (Guidance) is a
non-regulatory document that was adopted in September 2000 to assist
local air pollution control districts and air quality management
districts in making risk management decisions associated with the
permitting of new stationary diesel-fueled engines.
U.S. EPA LargeEngine (On-Highway and Nonroad Compression-Ignition) Certification Data:
U.S. EPA certifies (formally verifies) that engines sold in the U.S.
meet federal emissions standards. Each year, newly manufactured engines
must be certified, and engines certified in previous years must be
recertified. U.S. EPA publishes on the internet the information used to
certify these engines. The data below were extracted from the
2001 U.S. EPA Large
Engine (On-Highway and Nonroad Compression-Ignition) Certification Data.
To help District permitting engineers and the purchasers of
diesel-fueled stationary engines identify engines which will conform to
the
Risk Management Guidance (listed at the top
of this page), we have prepared summaries which identify engines in the
U.S. EPA Large Engine Certification Data database which have PM
emissions of < 0.149 g/bhp-hr.
Description of the Data:
- There are two
databases posted on this website - a "summary" table and an "extended"
table. Both include information for engines that emit 0.149 g/bhp-hr
particulate matter (PM) or less. The summary version includes only
diesel-fueled engines and a limited number of data columns. The summary
version is a subset of the extended version. The summary version can be
viewed online as an HTML file or it can be downloaded as an Excel
(*.xls) file for printing and data manipulation. The extended version
includes CI engines of all fuel types and all U.S. EPA data columns.
The data for engines using fuels other than diesel are italicized in
the extended table. The extended version is posted as an Excel (*.xls)
file which must be downloaded for viewing, printing, and data
manipulation.

Please view more
information regarding the data
and the definitions for the column headings and abbreviations or visit the U.S.
EPA site at www.epa.gov/otaq/certdat2.htm.
-
Only diesel-fueled
engines are included in the summary table. The data
for engines using fuels other than diesel are italicized in the
extended table.
-
In the extended
table you may sort by Manufacturer and then Engine Family to see the
relationship between the new submissions and corrections/modifications
to the new submissions.

U.S. EPA Sort Order to view the entries in the order they appear in the
U.S. EPA database.
- The
relevant data have been extracted from the voluminous U.S. EPA
database. Therefore, some entries have been deleted from both of the
tables. These include:
- Duplicate entries;
- Engines with particulate matter emissions greater than
0.149 g/bhp-hr;
- Engines that do not include PM emissions data.
