Table Information

The air pollutants listed in permit rules (NR 407) emissions inventory reporting rules (NR 438) and air toxics rules (NR 445) are listed in this table, which is in Excel 97 format.

How to use the Combined Chemical Excel table

This table has all of the air pollutants listed in either NR 406/407(permitting), NR 438 (Inventory), or NR 445 (air toxics) rules.

It uses filters which are located at the headings of each field, to filter out data of interest and can be used as a simple query tool, much like a database filter. Click on the black downward pointing arrows at the bottom-right of the column headers to see a list box of choices.

When you click on one of the choices from the list, only that choice is then shown in that field and the list is filtered. You can use the filter on more than one field to create a filter on these additional fields. Caution: If you ever can't find a chemical that you know is there, look for any filter arrows that are blue, then click on the arrow and choose "all". This will turn the filter off for that field and the filter arrow is now black.

Description of the fields:

Column A: This a column the user can "check" for air pollutants that interest the user. For example, if you put an X in this column, you could mark which chemicals are emitted by a facility. Furthermore, you could use different letters or numbers to represent parts of a facility or organization sub-divisions that had those chemicals. You would then use the filtering feature of Excel to filter the list for the chemicals of interest.

Column B: Chemical Name (Note: common synonyms are also listed in some cases, so the same CAS number may appear more than once).

Column C: Alphabetical sort column (use this column to sort chemicals alphabetically).

Column D: Chemical Abstracts Service Number (CAS number). Some CAS numbers represent multiple compounds there may be more than one CAS number that fits the category - for example, many metals are not listed individually. Example: "Cobalt, elemental, and inorganic compounds, as Co". For other chemicals there is no CAS number listed because the mixture is too complex to attribute a single CAS number to the listing -for example see "glycol ethers", "coke oven emissions", or "fluorides").

Column E: CAS number with dashes removed. Used for sorting and searching purposes.

Columns F, G, & H tell you what general types of health effects (non-cancer and cancer) are regulated for that chemical.

Column I: Use this column to filter out chemicals that are not listed in NR 445. This is done by clicking on the black downward pointing arrow (list box button) at the bottom-right side of the column header that says "Chems not in NR 445, but in permits and inventory" then choose "blanks". Any chemical that is not in NR 445 is filtered out and only the NR 445 chemicals remain. Note the list box button changes to the color blue and this lets you know that this field is filtered. Remember to turn this filter off when you are done by clicking on the black downward pointing arrow (list box button) again and choosing "all", which is at the top of the list box. If the list box button turns back to black, then the filter is off.

Column J: You can see how many health effects the chemical is regulated for. For example, some chemicals have a 24 hour acute non-cancer health limit, are also carcinogenic and have a US EPA reference concentration limit (chronic non-cancer) as well, thus they have "3" in this column. For chemicals not in NR 445, they will have a "0" in this column.

Column K: gives the NR 407 Permit Inclusion Level in pounds per year, as revised in the NR 445-rule proposal

Column L: gives the NR 438 Emissions Inventory Reporting level in pounds per year. The requirements for this reporting start with calendar year 2004 and the emissions reports are due by March 1, 2005.

Columns M-W are columns that are columns used for quality assurance purposes and are not important for the general user.

Column X is a column for filtering the list for new chemicals to the NR 445 list.

Column Y is for filtering chemicals that are in listed in the Clean Air Act Amendments of 1990, Section 112(b).

Column Z lists the NR 445 table that the chemical is in. If it says NR 407 and NR 438 only, it means that the chemical is not listed in NR 445.

Column AA to column BM: The remaining columns give the thresholds and standards for NR 445, as revised. If there is no threshold or standard listed under a given heading, it means that this threshold or standard is not applicable. The standards are in units of micrograms per cubic meter of air (ug/M3). The thresholds are either in units of pounds per hour (for non-carcinogens with acute health effects), or in pounds per year (for non-carcinogens with chronic health effects and for carcinogens). Columns BC to BF are for carcinogens and list the EPA and IARC weight of evidence, the unit risk factors (a measure of carcinogenic potency) and the source of the potency estimate.
