HAPsHelp Version 2
Using HAPsHelp HapsHelp has been created to assist manufacturers in identifying sources of hazardous air pollutants (HAPs) in their manufacturing facilities, because many manufacturers use industrial products that may contain some amount of a HAP. While there are also a smaller number of companies that either manufacture HAPs or purchase HAPs for use in a manufacturing process, these companies should have no difficulty identifying and estimating their emissions.
Here’s how to use HAPSHelp to identify sources of emissions for newly listed NR445 hazardous air pollutants, and other commonly reported HAPs:
1) Review the list of newly listed NR445 air toxics (see: Appendix) . Do you recognize any as chemicals that your company either manufactures, purchases as feedstock or produces as a process byproduct. If so, you must determine if you meet the definition of a regulated emitter under the rule, and if you do, calculate your emissions.
2) If possible, cross check your database of Material Safety Data Sheets (MSDS) against the list of NR445 chemicals using both the Chemical Abstract Service (CAS) number and the chemical name. If you find that your company purchases products containing regulated HAPs, search HAPsHelp for more information about the chemical.
If you do not have a MSDS database, you can use HAPsHelp to identify the types of industrial products used by your company that might contain a listed HAPs. If you have any of those products in your facility, manually check the MSDS for that product to determine if it contains the listed HAP.
3) Review the HAPsHelp chemical profile for the listed HAP to determine the likely source of emission of the chemical, and identify opportunities for emission reduction, or product substitution so you can eliminate it from your facility entirely.
How to Search in HAPsHelp HAPs Help utilizes the Adobe Acrobat Find option to help you locate the chemical profile you need. This search option is usually represented by the binocular icon, but can also be found in the Edit drop-down list. Either manually enter (or block and copy) the CAS number, or the chemical name or synonym into the search box, and your cursor will move to the appropriate profile. The name and CAS numbers of HAPs included in HAPSHelp are shown on the following list:
