SUPPORTING DOCUMENTATION ON 

 EMISSIONS UNIT BART ELIGIBILITY ANALYSIS

1.0 SOURCE WIDE BART ELIGIBILITY CRITERIA 

On April 4, 2005, the Stationary Sources Joint Forum (SSJF) of the Western Regional Air 

Partnership (WRAP) published a draft report identifying BART-eligible sources in the 

WRAP region. This report took a broad-brush approach to reviewing existing stationary 

sources of air pollution in order to determine whether or not emissions units at the facility 

could be considered to be BART-eligible. The report explains that the following series of 

steps were used to identify potentially BART-eligible facilities in the WRAP region: 

Step 1. Identify the facilities that have categorical sources (i.e. one of the 26 source 

categories); 

Step 2. Identify whether or not any of the emissions units at the facility are within the 

date range of BART; 

Step 3. Determine whether or not the potential emissions of the entire facility (all 

emissions units) are greater than 250 tons per year of visibility impairing 

pollutants. 
2.0 UNIVERSE OF BART ELIGIBLE SOURCES 

Appendix H of the April 4, 2005 draft report identifying potentially BART-eligible 

sources in the WRAP Region specifically identified a list of sources under the 

jurisdiction of the Arizona Department of Environmental Quality (ADEQ), the Maricopa 

Air Quality Department (MCAQD), the Pima County Department of Environmental 

Quality (PDEQ) and the Pinal County Air Quality Control District (PCAQCD). The list 

included the following sources:

3.0 CLARIFICATION OF PREVIOUSLY UNKNOWN, POTENTIALLY BART 

ELIGIBLE SOURCES 

 In addition to the sources identified in the previous section, several sources that were 

included in the October 18, 2005, update to Appendix H of the draft report identifying 

potentially BART-eligible sources in the WRAP region, were listed as “Do Not Know” 

under their BART eligibility. These sources have been reviewed, and it is recommended 

that their unknown status be changed as follows: 

 3.1 Forest Energy Corporation 

This facility is listed under BART Category ID – BART-18 - Fuel Conversion 

Plant. This facility creates wood pellets that can be burned as fuel, and has 

obtained a Class II air quality permit from the Arizona Department of 

Environmental Quality. This permit is a non-Title V permit, and contains 

limitations that restrict the potential emissions of visibility impairing pollutants to 

less than 100 tons per year of each pollutant. It is recommended that this source 

be listed as a non-BART eligible facility. 

3.2 Cyprus Casa Grande Corporation

This facility is listed under BART Category ID – BART 20 – Secondary Metal 

Production Facilities. It appears that this facility used to be a secondary copper 

smelter located around Casa Grande, Arizona. A search for this facility across the 

internet revealed that the Roaster\Leach\Acid plant for this facility was shut down 

in 1977, and that Cyprus Casa Grande Corporation was seeking an exemption 

from EPA from New Source Review/Prevention of Significant Deterioration 

(NSR/PSD) requirements in 1987. Memorandums from that time period indicate 

that EPA determined that the facility would trigger NSR/PSD requirements if 

these activities were restarted. 

Arizona Revised Statute Title 49, Chapter 3, Article 1, Section 402(a)(2) reserves 

original jurisdiction over smelting of metal ores for the Arizona Department of 

Environmental Quality. There is no record of this facility having obtained a Title 

V permit from that Department, or from the Pinal County Air Quality Control 

District. It is recommended that this source be listed as a non-BART eligible 

facility. 

3.3 Reynolds Metal Company

This facility is listed under BART Category ID – BART 20 – Secondary Metal 

Production Facilities. According to information found on the internet, Reynolds 

Metal Company and all of its assets were purchased by Alcoa Company in 2000. 

According to Alcoa’s Web site, it has two operations inside the State of Arizona. 

The first is a fabricated aluminum products facility located in Chandler, Arizona, 
named Pimalco, Inc. The second is a “related [aluminum] products” facility 

located in Tucson, Arizona, named Huck International, Inc. 

A review of Maricopa County Air Quality Department’s Web site revealed that no 

Title V application has been received, nor has a Title V permit been issued to 

Pimalco, Inc. A review of Pima County Department of Environmental Quality’s 

Web site revealed that no Title V permit has been issued to a company named 

Huck International, Inc. Because neither Department has issued a major source 

permit to either of these companies, it is unlikely that Pimalco, Inc. and Huck 

International, Inc. have the potential to emit visibility impairing pollutants at rates 

greater than 100 tons per year. It is recommended that this source be listed as a 

non-BART eligible facility. 

3.4 ASARCO – Ray Mine

This facility is listed under BART Category ID- BART 22 – Fossil fuel-fired 

boilers with a heat input capacity greater than 250 MMBtu per hour. This facility 

has obtained Title V Permit number V20600.R02 from the Pinal County Air 

Quality Control District for the operation of a copper mine. A review of this 

permit revealed that there are no fossil fuel fired boilers that have a heat input 

capacity of greater than 250 MMBTU/hr authorized by the permit. The remaining 

equipment on-site can not be listed in one of the other 25 source categories. 

Based upon this review, it is recommended that this source be listed as a nonBART eligible facility. 

3.5 Phelps Dodge Miami Smelter, Inc.

This facility is listed under BART category ID – BART 08 – Primary Copper 

Smelters. This facility has obtained Title V Permit number 1000046 from the 

Arizona Department of Environmental Quality. After reviewing this permit, it 

appears that this source meets the requirements of being listed as a BART eligible 

source. There appears to have been some recent modifications that may impact 

the application of BART to control SO2, but it has the potential to emit more than 

250 tons per year of other visibility impairing pollutants. Based upon the review 

of this permit, it is recommended that this source be identified as a BART eligible 

facility. 
4.0 EMISSIONS UNIT BART ELIGIBILITY CRITERIA 

 In order to establish whether or not emissions units at a facility are truly BART-eligible, 

EPA published final regulatory text and guidelines for implementing BART on June 15, 

2005. According to the language of the guidelines, there are three steps for determining 

which emissions units at a facility are considered to be BART-eligible. Those three steps 

are as follows: 

Step 1. Does the plant contain emissions units in one or more of the 26 source categories? 

 a. If no, then emissions units are not BART eligible. 

 b. If yes, proceed to Step 2. 

Step 2. Identify the start-up dates of emissions units identified in Step 1. Had the 

emissions unit begun operation after August 7, 1962 and in existence on August 

7, 1977? 

 a. If no, then emissions units are not BART eligible. 

 b. If yes, proceed to Step 3. 

Step 3. Compare the potential emissions from all emissions units identified in Steps 1 and 

2. Are the combined potential emissions of visibility impairing pollutants from 

these emissions units greater than 250 tons per year? 

 a. If no, then emissions units are not BART eligible. 

 b. If yes, then emissions units are BART eligible.

Notes: The facility also has 5 small industrial boilers rated at 20.9 

MMBtu/hr a piece, but all units are date ineligible. Facility is 

listed as likely to have a PTE > 250 TPY as 2004 actual emissions 

inventory showed no emissions from any of the BART eligible 

emissions units. Since they are active units on the permit, the one 

date eligible boiler is greater than 250 MMBtu/hr, the gas turbines 

are rated at 240 MMBtu/hr heat input, and the gas boileras are 

rated at 250 MMBtu/hr heat input, it is likely that these emissions 

units have a PTE > 250 TPY for NOx.
