U.S. EPA Promulgates HHRAP!

The U.S. EPA has recently promulgated and released an updated guidance of the Human Health Risk Assessment Protocol for Hazardous Waste Combustion Facilities (HHRAP).  Lakes Environmental has begun implementing changes to the IRAP-h View software package, with a new version of IRAP-h View to be released in the near future.  Users who are currently under maintenance will receive an email notice when the updates to IRAP-h View are complete.  For more information on the revised protocol, or for a copy of the guidance documentation, visit https://www.epa.gov/epaoswer/hazwaste/combust/risk.htm.

We’ve set a number of training dates for 2005 and 2006, with additional courses to be announced.  Please contact us at training@weblakes.com for international or customized training needs.

Plotfile Limit in ISCST3

When running the U.S. EPA ISCST3 model, you should be aware that there is a limit to the number of plotfiles that can be generated by this model.  The current EPA-compiled version of ISCST3 allows for a maximum of 30 plotfiles to be created during any given run.

This limit is a result of how the model was compiled.  Compared to AERMOD and ISC-PRIME, ISCST3 was compiled with a 16-bit compiler (see chart below):

Model	Dated	Compiler	Date Compiled
ISCST3.EXE	02035	Lahey Fortran 16-bit	Feb. 04, 2002
ISC3P.EXE	04269	Visual Fortran Win 32	Aug. 26, 2004
AERMOD.EXE	04300	Visual Fortran Win 32	Apr. 14, 2005

If you attempt to run an ISCST3 project with more than 30 plotfiles specified, you may encounter an error similar to the following:

“OU E500 5360 OUPLOT:Fatal Error Occurs Opening the Data File of PLTFL000”

where “PLTFL000” refers to the type of file and file unit number that is causing the error.  This fatal error will potentially occur for each plotfile that is in excess of the 30-plotfile limit.

ISC-AERMOD View users that are currently in maintenance can visit the update site at http://support.lakes-environmental.com/updates.html to download a recompiled version of ISCST3.EXE that is capable of generating a greater number of plotfiles.

We are currently accepting submissions for the Monthly Modeling Tip which appears in our newsletters.  If you have a modeling tip that may benefit a variety of people, please send it to us at support@weblakes.com.   Your name and the name of your organization will appear below the tip providing you with greater exposure.

Great Lakes are Suffering

The U.S. EPA could do more to ensure that states protect the eight Great Lakes, the Government Accountability Office (GAO) notes in a new report.  At the request of several members of Congress, GAO analysts reviewed how successful the states bordering the lakes and EPA officials have been in implementing the Great Lakes Initiative (GLI), a federal program designed to control toxic releases and protect aquatic life and wildlife.

Criteria and Air-Toxic Emissions from In-Use Automobiles in the National Low-Emission Vehicle Program

The U.S. Environmental Protection Agency (EPA) implemented a program to identify tailpipe emissions of criteria and air-toxic contaminants from in-use, lightduty low-emission vehicles (LEVs).  EPA recruited 25 LEVs in 2002 and measured emissions on a chassis dynamometer using the cold-start urban dynamometer driving schedule of the Federal Test Procedure.
