COMPLIANCE STATEMENT

Tucson Electric Power Company

H. Wilson Sundt

Irvington Generating Station

Unit#4

Operating Permit February 8, 1993. ADHS permit Number 0375-96, Emission Standards are as

follows:

Sulfur Dioxide @ 1.0 lb/MMBtu

Nitrogen Oxides @ 0.7 lb/million Btu

Particulates @ E=1.02Q 07

Where: E = the maximum allowable emissions rate in pounds-mass per

hour

Q = the heat input in million Btu per hour

Measured Emissions (06/8-9/1 1) were:

Low Load

Nitrogen Oxides @ 0.499 lb/MMBtu

Sulfur Dioxide @‘ 0.732 lb/MMBtu

High Load

Particulates @ E =

Q = 1,279.7 million Btu/hour

Therefore Allowable = 250.0 PPH

Measured = 28.49 PPH

All standards are Federally Enforceable unless otherwise noted

[References are to Title 17 of the Pirna County Code unless otherwise noted]

APPLICABILITY

Equipment covered by this permit constitutes a Major Source based on 8760 hours of operation per year

and considering emissions from other emission units of the same SIC Code at this facility. Equipment

specifically addressed by the permit is listed in Attachment D, Equipment List and falls under the

following Categories:

A. Fossil Fuel Fired Steam Generators

B. Stationary Rotating Machinery (including Stationary Turbines IGTI, IGT2 & future AOS for IGT3)

C. Auxiliary Boiler

D. Cooling Towers

E. Coal Preparation Plant

F Fly-Ash Handling Systems

G. Open Areas, Roadways, & Streets

H All Operations

Affected Emission Source Classification: Class 1; Major Stationary Source (SOx, NOx, CO, VOC, PM10

& HAPs).

II. EMISSION LIMITS & STANDARDS [PCC 712 180A2]

A. Fossil Fuel Fired Steam Generators

I. Particulate Matter Standard {PCC 17 16 60 C I]

[Locally Enforceable Condition]

The Permittee shall not cause. allow, or permit the emission of particulate matter from any

fossil fuel-fired steam generator in excess of the amounts calculated by the folloing equation:

E = I .02Q° where:

E = the maximum alloable particulate emissions rate in pounds-mass per hour.

Q = the heat input in million Btu per hour.

a. UNITSII.l2.&l3

The Permittee shall not cause, allow, or permit the emission of more than 1,0 pound of

sulfur dioxide as a three hour average per million Btu heat input when firing liquid fuel.

b. UNIT 14

The Permittee shall not cause, allow, or permit the emission of more than 1.0 pound of

sulfur dioxide as a three-hour average, per million Btu heat input.

[Installation Permit 56. Condition 5]

3. Nitrogen Oxides Standard - UNIT 14

The Permittee shall not cause, allow, or permit the emission of more than 0.7 pounds of

nitrogen oxides as a three hour average (calculated as nitrogen dioxide) per million I3TU heat

input. [Instaflation PermitS 156. Condition 5]

4. Opacity Standard - UNIT 14

The Permittee shall not cause, allow, or permit to be emitted into the atmosphere any plume or

effluent from the boiler which exceeds 20 percent opacity, as measured in accordance with

EPA Reference Method 9. [Installation Permit l 56. Conditions]

5. Fuel Limitations

a. The Permittee shall not use high sulfur oil (fuel sulfur content> 0.90% by weight) as a

fuel unless the Permittee demonstrates to the satisfaction of the Control Officer that

sufficient quantities of low sulfur oil are not available for use by the source and that it has

adequate facilities and contingency plans to insure that the sulfur dioxide ambient air

quality standards set forth in 17.08.020 will not be violated. [PUC 7 I 61 (1
