ARB is currently updating the HARP software. This latest version is different from the previous versions of HARP.
The new version of HARP has been separated into three individual programs (Emission Inventory Module, Air Dispersion Module, and the Risk Assessment Module)
which will allow users to access any of the modules independently from each other. As in the previous version, the information can still be shared between each program.
For consistency, the three programs are still referred to as the Emission Inventory Module, Air Dispersion Module, and the Risk Assessment Module.
The new version of HARP will also include AERMOD and the updates to the OEHHA “Hot Spots” Risk Assessment Guidelines. ARB anticipates on having the Air Dispersion and
Risk Assessment Modules available within six months to a year after the final part of the OEHHA “Hot Spots” Risk Assessment Guidelines is adopted.
At this time, the HARP 2 Emission Inventory Module is being released for a 30-day public review/testing period.
During this testing period, please submit any comments or issues discovered to harp@arb.ca.gov.
The deadline to submit comments is May 6, 2013. If you would like to test the new HARP 2 Emission Inventory Module, you may download the installation package and draft user manual
at http://www.arb.ca.gov/toxics/harp/downloads.htm.

A new HARP Health Database is now available. This database
contains updated health values for polychlorinated dibenzo-p-dioxins
(PCDDs), dibenzofurans (PCDFs), and dioxin-like polychlorinated
biphenyls (PCBs). The new health values have been revised to reflect the Office of Environmental Health Hazard
Assessment‘s adoption of the World Health Organization’s 2005 Toxicity
Equivalency Factors for PCDDs, PCDFs, and dioxin-like PCBs .
The new HARP Health Database can be downloaded. To use it
with HARP, you must replace your current health database located in the
HARP main directory (typically C:\HARP) with the one you just
downloaded.
The new health database is also available for the HARP On-Ramp. To
use this health database, you must replace the current database
typically located at “C:\Program Files\CARB\HARP On-Ramp\Tables” with
this one. Please note that it
is not necessary to update HARP On-Ramp’s Health Database as the new
health values for PCDDs, PCDFs, and dioxin-like PCBs are not used by
the HARP On-Ramp. However, if you decide to update the database,
it would be only for display purposes (i.e., showing the current health values).

HARP
Air Dispersion Module and Health Risk Assessment Module Survey
The
California Air Resources Board (ARB) staff invites you
to participate in the HotSpots Analysis and Reporting Program (HARP)
survey.
Currently, ARB is in the process of
redeveloping the HARP
software.
Our intent is to collect general information
on your current air dispersion
modeling and risk assessment practices and future HARP needs.
Your input will be used to
help prioritize
our work on the HARP
software.
The HARP Air
Dispersion Module and Health Risk Assessment Module Survey can be
downloaded.
Your
participation and response to the survey
is greatly appreciated. ARB is
requesting that you send your completed survey to Hafizur Chowdhury
by July
17, 2009.
If
you have any questions, please call the Emission Assessment Branch of
Stationary Source Division at (916)
322-2275
or send
email in care of Hafizur Chowdhury. |

The
HARP Health
Database has been updated. Under directions from OEHHA, the
oral
chronic Reference Exposure Level (REL) for arsine was
removed. In
addition, acute RELs with longer averaging periods (e.g., 4-hr, 6-hr,
and 7-hr) will now use the 1-hr averaging period. This
includes:
- Arsenic & inorganic arsenic compounds
- Benzene
- Carbon disulfide
- Carbon tetrachloride
- Chloroform
- Ethylene glycol monoethyl ether
- Ethylene glycol monoethyl ether acetate
- Ethylene glycol monomethyl ether
You may download the February 2009 version of the health database.
In order to use the new health database, you must replace the health
database (health.mdb) under the HARP program directory (typically
c:\HARP) with this file.
For more information on the changes to the HARP Health Database, please
download the zip file.
Note that changes made in January are also included in this file.

A
file was
inadvertently left out of the HARP full setup file (HARP Version
1.4). This file is
used for the new Keyhole Markup Language feature which exports the risk
contours from the HARP Risk Module to Google Earth. If you
have
downloaded and installed the full setup file prior to 6/25/2008, you
can get the missing file by downloading and installing the
patch (harppatch062008.exe). |

A
clarification has been made to the HARP Health
Database. The May 2008 version of the database contains an
oral cancer potency value for ethylbenzene. HARP was not using
this value to calculate multipathway risk. The Office of
Environmental Health Hazard Assessment has determined that ethylbenzene
is not a multipathway pollutant for the Air Toxics “Hot Spots” Program
Therefore, to avoid confusion, the oral cancer potency value has been
removed from the June 2008 version of the HARP Health Database
(health.mdb).
Please download the June
2008 version of the Health.mdb and save it to your HARP
program directory
(usually C:\HARP). The new Health.mdb will overwrite the
existing version of the health database (May 22, 2008). |
