SUMMARY:        

To help all stakeholders better understand the proposed guidelines we have reformatted already publically available information and are making this information available in the docket.

EMISSION COMPARISON BETWEEN NATURAL GAS COMBINED CYCLE (NGCC) AND CONVENTIONAL COAL FIRED UNITS
This table provides an emissions comparison between filterable PM, SO2, NOx, Hg and for natural gas combined cycle and conventional coal fired units.

Location of recent NGCC builds
The attached file "New Combined Cycle Units since 2010" contains all the combined cycle units in the most recent EIA-860 data file (year 2012) having start dates in year 2010 or after. Electric generating units are included, while commercial and industrial units are excluded. Proposed units that are either under construction or have received regulatory approval are included, while units having a status code of regulatory approval pending or regulatory approval not yet initiated are excluded. EPA staff also examined the most recent EIA-923 monthly (2014 with data though August) and did not find any additional new combined cycle units to add to the list.

There are four tabs in this file. The first tab subtotals the units' nameplate capacity, summer capacity and winter capacity by state. The second tab subtotals the units' nameplate capacity, summer capacity and winter capacity by county. The third tab displays all the units. The fourth tab contains notes on source data and criteria for inclusion. Some EIA-860 fields that had no relevant data to these combined cycle units (e.g., pulverized coal technology) were removed. Some code description fields were added from the EIA-860 layout file (i.e., prime mover description, energy source description, status code description, and ownership description). 

Information on all fossil-fuel fired electric generating units (EGUs)
The attached file "NEEDSv513 Subset Data includes state, county and unit level data for existing fossil-fuel fired EGUs (e.g., coal, oil and natural gas). Some examples of information included are: addresses of facilities, energy source of the unit and the facility's operating status. The facility locations used in this spreadsheet are the same as those used for the publically available interactive maps available at:  http://www2.epa.gov/carbon-pollution-standards/where-you-live /.
