Mahoning Renewable Energy

  1. Name of the facility: 
    Mahoning Renewable Energy
  2. Location: 
    12003 Oyster Rd., Alliance, Ohio  44601  Mahoning County
  3. Distance from the US/Canada border: 
    Approximately 100 km
  4. Type/size of the facility: 
    Two 535 mmBtu/hr refuse-derived fuel stoker boilers, refuse 
handling, ash handling, grinders, roadways and parking 
areas and a 66 MW gross (58 MW net) steam turbine generator.
  5. Source of emissions: 
    Two 535 mmBtu/hr refuse-derived fuel stoker boilers
  6. Type of fuel: 
    Refuse-derived fuel processed from municipal solid waste and 
construction and demolition debris
  7. Type and quantity of emission increases: 
    BAT emission limitations under OAC rule 3745-31-05(A)(3) for each boiler:

 - 0.5 ppm of hydrogen fluorides (HF)
 - 15.0 ppm of ammonia

    

Annual emissions from this emissions unit shall not exceed any of the following:

 - 35.0 tons/year of particulate matter (PM)/particulate matter less than 
   10 microns in diameter (PM10)
 - 0.30 ton/year of lead
 - 81.5 tons/year of sulfur dioxide (SO2)
 - 31.3 tons/year of hydrogen chloride (HCl)
 - 0.00013 ton/year of dioxins/furans
 - 292.0 tons/year of nitrogen oxides (NOx)
 - 261.5 tons/year of carbon monoxide (CO)
 - 12.2 tons/year of sulfuric acid
 - 0.040 ton/year of cadmium
 - 0.07 ton/year of mercury
 - 0.60 ton/year of hydrogen fluorides
 - 16.1 tons/year of ammonia

    

BACT emission limitations under OAC rule 3745-31-10 through 20 for each boiler:

    

 - PM/PM10 shall not exceed 20 milligrams per dry standard cubic meter, 
corrected to 7 percent oxygen (this limit is identical to Subpart Eb below).

    

 - Lead emissions shall not exceed 140 micrograms per dry standard cubic meter, 
corrected to 7 percent oxygen (this limit is identical to Subpart Eb below).

    

 - SO2 emissions shall not exceed 24 parts per million by volume or 20 percent of 
the potential SO2 emission concentration (80-percent reduction by weight or volume), 
corrected to 7 percent oxygen (dry basis), whichever is less stringent. This shall 
be based on a 24 hour averaging time as specified in §60.58b(e) (this limit is more 
stringent than Subpart Eb below).

    

 - HCl emissions shall not exceed 25 parts per million by volume or 5 percent of 
the potential HCl emission concentration (95-percent reduction by weight or volume), 
corrected to 7 percent oxygen (dry basis), whichever is less stringent (this limit 
is identical to Subpart Eb below).

    

 - Dioxin/furan total mass emissions shall not exceed 13 nanograms per dry standard 
cubic meter (total mass), corrected to 7 percent oxygen (this limit is identical 
to Subpart Eb below).

    

 - NOx emissions shall not exceed 75 parts per million by volume, corrected to 
7 percent oxygen (dry basis). This shall be based on a 24 hour averaging time 
as specified in §60.58b(h) (this limit is more stringent than Subpart Eb below).

    

 - CO emissions shall not exceed 150 parts per million by volume, corrected to 
7 percent oxygen (dry basis).  This shall be based on a 24 hour averaging time 
as specified in §60.53b(a) (this limit is identical to Subpart Eb below).

    

 - Sulfuric acid emissions shall not exceed 2.0 parts per million by volume 
corrected to 7 percent oxygen (dry basis).
