New Source Review (NSR) Permitting

Mahoning Renewable Energy - Permitting Information

1. Facility Information

Mahoning Renewable Energy

2. Location

12003 Oyster Rd., Alliance, Ohio  44601  Mahoning County

3. Distance from US/Canada Border

Approximately 100 km

4. Facility Type and Size

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. Sources 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 Emissions

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).
