CEMS is a database used by the Pennsylvania Department of Environmental Protection to monitor key pollutants and/or operational parameters to demonstrate compliance with emissions standards or operational criteria as stipulated in a plan approval, operating permit, or order.
The owner or operator of a source may be required to install and operate a PA DEP certified continuous emission monitoring system (CEMS) to satisfy a condition in a plan approval, operating permit, or order. CEMS data is used to demonstrate compliance with emissions and data availability standards. Generally speaking, a CEMS is the total equipment necessary for the determination, collection, and reporting of a pollutant or parameter in the applicable units of measurement. It includes the measurement interface, all necessary measurement devices and associated calibration and data handling apparatus and procedures. Systems are evaluated on an individual basis and the PA DEP does not maintain an approved list of equipment.

Most of the CEMS related activity takes place in the CEM Data Processing System (CEMDPS). Regulated entities construct work items in the CEMDPS that are submitted to the PA DEP for review. The owners or operators of PA DEP certified CEMS are required to submit emissions data to the Department through the CEMDPS each calendar quarter. The PA DEP reviews the emissions data and generates a report which is provided to the owners or operators of the regulated source. The hourly emissions data submitted by the owners or operators of the source will be reviewed by the PA DEP and ultimately provided to the public through the Open Data Porta on the www.pa.gov website. This data will be updated quarterly.

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

EDDIE is an interactive health statistics dissemination web tool where you can create customized data tables for various health related data.

The EDDIE system was developed to empower public health professionals by enhancing and expanding upon their ability to use data and statistics to drive public health policy and program decisions. Users of the EDDIE system must agree to make no attempt to identify an individual, and must agree to notify the Pennsylvania Department of Health, Division of Health Informatics immediately if an individual is inadvertently identified along with an explanation on how this occurred.

The following datasets are available:
•Air Quality
•Behavioral Risk Factor Surveillance System (BRFSS)
•Birth Defects
•Births
•Cancer Incidence
•Carbon Monoxide Poisoning Mortality
•Childhood Cancer Incidence
•Childhood Lead Poisoning
•Children Less Than Age 5 Living in Poverty
•Communicable Diseases (other than STDs)
•Deaths
•Drinking Water Quality
•Hospitalizations
•Housing by Year Built
•Infant Deaths
•Population
•Reported Pregnancies
•Reproductive Health Outcomes
•Sexually Transmitted Diseases (STDs)

EDDIE is the Pennsylvania Department of Health's primary tool for data dissemination. This is also the replacement for our legacy EpiQMS system, which has been disabled. We are working to add additional functionality to the EDDIE system in the future, including charts, county assessments, and additional maps. We are also planning to add new datasets in the coming years.
