Emissions Inventory System (EIS) Emissions 2017 - Current Semi-Annual County Environmental Protection

Emissions Inventory System (EIS) Emissions 2017 - Current Semi-Annual County Environmental Protection

EPA's Emissions Inventory System (EIS) contains information about sources that emit criteria air pollutants (CAPs) and hazardous air pollutants (HAPs). The EIS includes estimates of annual air pollutant emissions from point, non-point, and mobile sources in the Pennsylvania counties. EPA collects information about emission sources and releases an updated version of the NEI database every three years. The data made available in the NEI are used for air dispersion modeling, regional strategy development, setting regulations, air toxins risk assessment, and tracking trends in emissions over time. The data derived in the State of Pennsylvania is published and searchable online on the website.

This data will be updated annually for the prior calendar year in the first Quarter of the following year.

PollutantpollutantpollutantTextThe pollutant which is controlled by the control measure. The number prefixes are part of the chemical name describing the isomer ( ions or molecules with identical formulas but distinct structures ) part of the name. For example - 1,2,3,4,5,6 refer to the positions on the cyclohexane molecule where a chlorine atom is substituted for a hydrogen. The carbon atoms on the cyclohexane ring can be numbered 1 through 6. Due to the symmetry of this particular molecule, it doesn’t really matter where we start counting on the ring. What does matter is that each number is only mentioned once, which means there is only 1 chlorine atom attached to each carbon. One can envision other forms of Hexachlorocyclohexane in which multiple chlorines are attached to a single carbon atom. For example: 1,1,2,2,3,3 Hexachlorocyclohexane would have two chlorine atoms attached to each of 3 sequential carbon atoms, with none on the other three… Now 1,2,3,4,5,6 Hexachlorocyclohexane can refer to a mixture of isomers of that molecule. This is because the ring of cyclohexane’s carbon atoms locks the attached hydrogens and chlorines onto one side of the ring, and this naming convention is not specific enough to tell which chlorine atoms are locked “above” the ring and which are “below it”. So in order to know which specific isomer we are talked about, a more specific name is required. This is where the other numbers can help. “58-89-9” is the Chemical Abstracts Service (registration) number, sometimes abbreviated CAS # or CASRN. This is really not part of the name of the molecule, but rather a unique serial number assigned to the molecule. The number itself is pretty much arbitrarily assigned by the American Chemical Society, but it is important in that it is unique, like a bar code for the molecule. The number is typically written in 3 parts separated by dashes, with two to seven digits in the first part, two in the second, and one in the third. If we google CAS#58-89-9 we find out that we are working with the “gamma” isomer of 1,2,3,4,5,6 Hexachlorocyclohexane where the chlorines are arranged around the ring in an up-up-down-up-up-down configuration. This is also known as “Lindane” a chemical which has been used as an insecticide and a pharmaceutical.
