All industrial permits sources were reviewed to insure that appropriate
requirements had been applied and that these requirements constituted
RACT. The following are thirteen sources that had the highest sum of
emissions of combined NOx, SO2, and Particulate. Particulate was used
because PM2.5 emission factors are limited. These sources were reviewed
to verify that the sources were subject to RACT levels of controls.

Industrial emissions were reviewed to see if there was a possibility of
any additional controls that could change the attainment date from the
end of 2009 to the end of 2008. No additional controls were found. Table
15 shows that no possible reductions will result in a 2008 attainment.

compliance.

Allowable Emissions:	Particulate	46.31 tons per year

			NOx		41 tons per year

			SO2		0.18 tons per year  Natural Gas Combustion only 

This source is subject to the following rules.

	1. 40 CFR Part 60 Subpart DC – Standards of Performance for Small
Industrial –

		Commercial-Institutional Steam Generating Units

	2. Particulate	Rule 10 

	3. Opacity	Rule 3

Three boilers on site are fired by natural gas only.

One 21.32 million BTU/hr boiler

One 15.7 million BTU/hr boiler  

One 30.1 million BTU per hour boiler 

	

The 15.7 million BTU/hr Boiler is subject to 40CFR Part 60 Subpart
Dc-Standards of Performance for Small
Industrial-Commercial-Institutional Steam Generating Unit.

rate. Process emissions are controlled by baghouses. 

East Tennessee Natural Gas

Company Number	5340

Full Compliance Evaluation March 29, 2007. The source was in compliance

Emissions	Particulate is 2.24 tons per year.  All particulate is PM2.5.

		Allowable NOx 48.20 Tons per year. 		

	

Subject to the following as adopted into the Chattanooga Air Pollution
Control Ordinance

	

1. 40 CFR Part 60 Subpart GG Standards of Performance for Stationary Gas
Turbines.

2. Chattanooga Air Pollution Control Ordinance Rule 15 Adoption of NSPS 

 

Both turbines burn pipeline natural gas and have been stack tested. The
allowable NOx limit in the NSPS is 150 ppm. The older turbine which was
tested in 1991 demonstrated NOx emissions of 63 ppm or 3.7 lb/hour. The
newer turbine which was tested in 2002 demonstrated NOx emissions of
14.2 ppm or 2.72 lb/hr. If both turbines ran 8760 hours, the potential
emissions would be 28.12 tons per year. 

Fuel sulfur has also been demonstrates as 0.02 % which is well below the
NSPS allowable of 0.08%. 

Particulate is likely to be overestimated as discussed in the emission
inventory document that said that particulate emissions from combustion
of natural gas are significantly overestimated.

in compliance 

Allowable/ Actual Emissions	Particulate 	11.87	 TPY

SO2 is limited by the permit to 500,000 gallons on Number 2 fuel oil
with 0.5% sulfur. 

There are 4 permitted boilers that provide steam for a large medical
center. The boilers are fired on natural gas but use Number 2 fuel as a
backup fuel. Depending on steam demand one or two boilers will be
operated at a time.  Though the facility is permitted for Number 2 oil
with 0.5% sulfur oil, the facility used 3600 gallons and the number 2
oil was 0.1865 % Sulfur in the last year.

Memorial Hospital RACT

Company Number 2010

Full Compliance Evaluation was completed on December 21, 2006. The
source was in compliance. 

This permit applies to the three 500 hp Johnson boilers that provide
steam for Memorial hospital. Natural gas is used to fire the boilers
with number 2 fuel oil as a backup fuel in case of natural gas
curtailment. By permit condition, only 2 boilers can be in operation at
a time.

Rock Tenn Converting Company

Company Number 47-065-3455

Full Compliance Evaluation completed on December 12, 2006. Source was in
compliance 

Allowable Emissions	Particulate 	23.074 TPY

			NOx		96.76	TPY

			SO2		349.19 TPY

Allowable emissions are based on 2% sulfur content and 3,500,000 gallons
per year. Actual oil sulfur content is normally considerably less than
2%. Natural gas is the primary fuel and is used when it is available and
is cost competitive. 

This source is subject to the following;

40 CFR Part 70 Operating Permit Program

The following local rules;

		1. Particulate	Rule 26.6

		2. Opacity	Rule 3

		3. VOC	Rule 25.3

		4. SO2		4-60(d)(9)

 Actual emissions from the boilers in the last year are as follows

			Particulate 	15.25 TPY

			NOx		73.92 TPY

			SO2	          174.97  TPY

The lower actual emissions occurred because the facility used Number 6
fuel with a sulfur content of 1.61 % for the first 6 months and 0.99%
for the second six months of the year. 

This source is a candidate for contingency measures. Specifically, the
oil sulfur limit may be further restricted.
