NR 438.04 Note
1Chemical Abstract Service or CAS number refers to the unique chemical abstracts service registry number assigned to a specific chemical, isomer or mixture of chemicals or isomers and recorded in the CAS chemical registry system by the Chemical Abstracts Service, PO Box 3012, Columbus, OH 43210, phone 1-614-447-3600.
2Indicates contaminants for which multiple CAS numbers may apply. For contaminants listed as a metal and its compounds, the given CAS number refers to the metal.
3Indicates contaminants for which a fee will be assessed under s.
NR 410.04. Emissions of all compounds listed in s.
NR 400.02(162)(b) shall be included when determining fees for volatile organic compounds.
4Indicates compounds included in the glycol ethers group. In addition to being reported individually when a compound's emissions are above the reporting level, the emissions of these compounds are included in the glycol ethers emission total reported along with emissions of the many other such compounds not listed individually by name.
5Glycol ethers include mono- and di-ethers of ethylene glycol, diethylene glycol, and triethylene glycol, R-(OCH
2CH
2)
n-OR'
where:
n=1, 2 or 3
R=alkyl C7 or less or
R=phenyl or alkyl substituted phenyl
R'=H or alkyl C7 or less or OR' consists of carboxylic acid ester, sulfate, phosphate, nitrate or sulfonate.
6Organic compounds that are not VOC and should not be considered or included here are specified in s.
NR 400.02 (162) (a). Emissions of organic compounds specified in s.
NR 400.02 (162) (b) shall be considered to determine if the reporting level for VOC is exceeded. Emissions of these compounds, however, shall be reported separately as the individual compound if the reporting level for VOC is exceeded.
7Any amount of emissions of this compound shall be reported if the reporting level for VOC emissions is exceeded. See footnote 6 for how to determine if the reporting level for VOC emissions is exceeded.
