Description of the source (including control equipment). Please see the attachments for source or process flow diagram: American Bituminous operates a coal refuse fired power plant in Grant Town, West Virginia referred to as the Grant Town Station.
The Grant Town Station generates electricity with the steam supplied from two circulating fluidized bed combustion (CFB) boilers with a maximum rating of 551.9 MMBtu/hr each. The primary fuel is coal refuse supplemented with pond fines. Natural gas is used as a startup fuel.
Limestone is injected directly into the furnace combustor for control of sulfur dioxide emissions. High fluidization velocities promote circulation of solids which provides more efficient combustion, emissions control, and heat transfer. Employing limestone as the sorbent material in the fluidized bed removes sulfur dioxide (SO2) at an efficiency of 90 to 94.8%. The addition of limestone to the coal refuse at the combustion chamber is integral to the design and operation of the CFB boilers. Once the sulfurization process has occurred, the remaining calcium sulfate is removed from the boiler in the bottom ash and fly ash streams.
Gases and particulate matter (PM) produced from combustion then move through a hot cyclone where heavy particles and ash are separated from the fine particulate hot exhaust gas. The hot exhaust gases then pass through a baghouse for capture of fine particulates. Both boiler units discharge through a common stack.
The CFB boiler technology produces lower levels of nitrogen oxides (NOx) than other combustion technologies. The CFB boilers operate at a relatively low temperature in the combustion zone producing less thermal NOx. Industry/SCC/NAIS221112

Chlorine data for Method 26A analysis is not available from the laboratory.

Method 26A & CTM033 The MDLs are determined by the analysis of at least seven replicate standards at a concentration near the expected MDL. To determine the MDL value, the standard deviation of the replicate analyses is calculated and that number is multiplied by the Student t factor that corresponds to the number of replicates analyzed. The MDL value should meet the criteria stated in the CFR Title 40, Part 136 B.

If the MDL determined does not meet these criteria, a default MDL value will be used which is 1/10 of the concentration of the standard used to produce the MDL value. Stack Exit

Filterable PM2.5 OTM - 27/28 3 300 0 Back half particulate matter (OTM-028) mass was calculated using the maximum allowable blank correction value of 0.002 g. A correction value of 0.001 g was used for each fraction (organic and inorganic) for a total correction of 0.002 g.

Method OTM-028 A portion of reagent water that has been spiked with a known amount of material is extracted 3 times with Methylene Chloride. The solvent is evaporated to dryness. Detection Limits are calculated by using the standard deviation from these 10 replicate low level spikes. The standard deviation is multiplied by the appropriate Student T value to determine the statistically derived reporting limit. The non-extractable portion is determined by the weight difference on a series of 10 vials. Detection Limits are calculated by using the standard deviation from these 10 replicates. The standard deviation is multiplied by the appropriate Student T value to determine the statistically derived reporting limit.

Cobalt Method 29 3 240 0 Method 29 For Method 29 the analyst takes the statistically determined MDL (Method Detection Limit) value and multiplies it by a “factor” in order to determine the RDL (Reporting Detection Limit). This process is similar to the one employed in Method 23 where the EDL is determined based on a constant factor of 2.5 times the signal to noise ratio.

For the ICP/MS this “factor” can vary. The factor is determined by the analyst at the bench and takes into account all relevant factors such as, final volumes, interferences, matrix issues, etc. The RDL (Reporting Detection Limit) reported is the lowest concentration that the lab feels can be reported within the 99% confidence interval. For values below this RDL the uncertainty increases. Section 5.5.5.2.2.1 bullet H refers to the ICP/MS procedure. Stack Exit
