GENERAL PERMIT CONDITIONS

TERMINATION OF PERMIT TO INSTALL

Substantial construction for installation must take place within 18 months of the effective date of this permit. This deadline may be extended by up to 12 months if application is made to the Director within a reasonable time before the termination date and the party shows good cause for any such extension.

NOTICE OF INSPECTION

The Director of the Ohio Environmental Protection Agency, or his authorized representatives, may enter upon the premises of the above-named applicant during construction and operation at any reasonable time for the purpose of making inspections, conducting tests, or to examine records or reports pertaining to the construction, modification or installation of the source(s) of environmental pollutants identified within this permit.

CONSTRUCTION OF NEW SOURCES

The proposed source(s) shall be constructed in strict accordance with the plans and application submitted for this permit to the Director of the Ohio Environmental Protection Agency. There may be no deviation from the approved plans without the express, written approval of the Agency. Any deviations from the approved plans or the above conditions may lead to such sanctions and penalties as provided under Ohio law. Approval of these plans does not constitute an assurance that the proposed facilities will operate in compliance with all Ohio laws and regulations. Additional facilities shall be installed upon orders of the Ohio Environmental Protection Agency if the proposed sources are inadequate or cannot meet applicable standards.

If the construction of the proposed source(s) has already begun or has been completed prior to the date the Director of the Environmental Protection Agency approves the permit application and plans, the approval does not constitute expressed or implied assurance that the proposed facility has been constructed in accordance with the approved plans. The action of beginning and/or completing construction prior to obtaining the Director's approval constitutes a violation of Ohio Administrative Code (OAC) Rule 3745-31-02. Furthermore, issuance of the Permit to Install does not constitute an assurance that the proposed source will operate in compliance with all Ohio laws and regulations. Approval of the plans in any case is not to be construed as


an approval of the facility as constructed and/or completed. Moreover, issuance of the Permit to Install is not to be construed as a waiver of any rights that the Ohio Environmental Protection Agency (or other persons) may have against the applicant for starting construction prior to the effective date of the permit. Additional facilities shall be installed upon orders of the Ohio Environmental Protection Agency if the proposed facilities cannot meet applicable standards.

PERMIT TO INSTALL FEE

In accordance with Ohio Revised Code 3745.11, the specified Permit to Install fee must be remitted within 30 days of the effective date of this permit to install.

PUBLIC DISCLOSURE

The facility is hereby notified that this permit, and all agency records concerning the operation of this permitted source, are subject to public disclosure in accordance with OAC Rule 3745-49-03.

APPLICABILITY

This Permit to Install is applicable only to the contaminant sources identified. Separate application must be made to the Director for the installation or modification of any other contaminant sources.


BEST AVAILABLE TECHNOLOGY

As specified in OAC Rule 3745-31-05, all new sources must employ Best Available Technology (BAT). Compliance with the terms and conditions of this permit will fulfill this requirement.

PERMIT TO OPERATE APPLICATION

A Permit to Operate application must be submitted to the appropriate field office for each air contaminant source in this Permit to Install. In accordance with OAC Rule 3745-35-02, the application shall be filed no later than thirty days after commencement of operation.

SOURCE OPERATION AFTER COMPLETION OF CONSTRUCTION

This facility is permitted to operate each source described by this permit to install for a period of up to one year from the date the source commenced operation. This permission to operate is granted only if the facility complies with all requirements contained in this permit and all applicable air pollution laws and regulations.

3. Compliance with the emission limitation in additional general term and condition A.3 of this permit to install shall be determined by the following equation:

(A + B + C + D + E) < 1210.69 TPY

Where,

A = rolling, 12-month emissions of NOx from Coke Batteries A1 and A2, including pushing, charging and waste gas emissions(emissions unit P920);

B = rolling, 12-month emissions of NOx from Coke Batteries B1 and B2, including pushing, charging and waste gas emissions(emissions unit P921);

C = rolling, 12-month emissions of NOx from Boiler (emissions unit B027);

D = rolling, 12-month emissions of NOx from Boiler (emissions unit B028); and,

E = rolling, 12-month emissions of NOx from No. 3 Blast Furnace Flare(emissions unit P925).

Additionally, during the first 30 days after startup of either emissions unit B027 and B028, the permittee shall include the emissions of NOx from emissions units B007, B008, B009 and B010 for the purposes of determining compliance with additional general term and


condition A.3. The NOx emissions from emissions units B007, B008, B009 and B010 shall be determined by multiplying the lbs NOx/MMBtu, as determined by the most recent stack test, by the MMBtu heat input rate for each emissions unit.

The rolling, 12-month emissions of NOx from each operation identified above (A - E) shall be determined by the following methods:

a. the annual emissions of NOx from Coke Batteries A1 & A2 shall be determined by multiplying the emission factor for coke oven charging and pushing emissions of 0.01603 lb NOx/wet ton of coal charged by the wet tons of coal charged/month, plus the calculated lbs NOx/wet ton coal charged, as demonstrated during the most recent stack test of the coke oven battery waste gas exhaust, times the tons of coal charged per month; adding the current month’s emissions rate to the emission rate for the preceding eleven month’s;

b. the annual emissions of NOx from Coke Batteries B1 & B2 shall be determined by multiplying the emission factor for coke oven charging and pushing emissions of 0.01603 lb NOx/wet ton of coal charged by the wet tons of coal charged/month, plus the calculated lbs NOx/wet ton coal charged, as demonstrated during the most recent stack test of the coke oven battery waste gas exhaust, times the tons of coal charged per month; adding the current month’s emissions rate to the emission rate for the preceding eleven month’s;

c. the annual emissions of NOx from the boiler (B027) shall be determined by adding the NOx emissions rate for each day of the calendar month, as determined by the NOx CEM; adding the current month’s emissions rate to the preceding eleven calendar month’s;

d. the annual emissions of NOx from the boiler (B028) shall be determined by adding the NOx emissions rate for each day of the calendar month, as determined by the NOx CEM; adding the current


month’s emissions rate to the preceding eleven calendar month’s; and,

e. the annual emissions of NOx from the No. 3 Blast Furnace Flare shall be determined by multiplying the total monthly quantity of BFG burned in the No. 3 Blast Furnace Flare, in MMcf/month by 23 lbs NOx/MMcf; adding the current month’s emissions rate to the preceding eleven calendar month’s.

4. The emissions reduction for PM from the flame suppression system (emissions unit P925) shall be determined by multiplying the uncontrolled emission factor of 0.6 lb PM/ton of pig iron by (1 - flame suppression system control efficiency) then times the tons of pig iron produced per year . The flame suppression system control efficiency is 50 percent.

5. The emissions reductions for PM10 from the flame suppression system (emissions unit P925) shall be determined by multiplying the uncontrolled emission factor of 0.31 lb PM10/ton of pig iron by (1 - flame suppression system control efficiency) then times the tons of pig iron produced per year. The flame suppression system control efficiency is 50 percent.

F. Miscellaneous Requirements

1. None.
