Subject: Number of EPA Protocol Gas Production Sites

On October 30, 2009, an EPA contractor responded to an inquiry from John Schakenbach of the 

Environmental Protection Agency (EPA) regarding the number of EPA Protocol gas production sites in the 

U.S. The EPA contractor conducted a survey to identify specialty gas companies which produce gas standards 

(tri-blends containing SO2, NO, and CO2) that are prepared and certified according to EPA’s Traceability

Protocol. Internet searches and review of previous EPA audit publications were performed to develop a list of 

specialty gas producers for consideration as audit candidates. Specialty gas companies and their production 

sites identified by a 2008 EPA study were also reviewed and served as a “baseline” list of producers. The 

survey identified 14 specialty gas companies, some with several production sites each, which produce EPA 

Protocol gas standards. There are other companies that only distribute Protocol gases. The specialty gas 

companies are:

1. Airgas

a. Also known as Airgas Specialty Gases/Airgas National Welders/ Linde/BOC.

b. Purchased AGA Gas, Inc. in Ohio.

c. Claims to be the largest specialty gas network in the U.S.

d. State they manufacture EPA Protocols at six laboratories, but do not identify them.

2. Air Liquide America

a. Purchased Scott Specialty Gases in 2007.

b. Locations nationwide.

3. Liquide Technology Corporation

4. Matheson Tri-Gas

5. MESA Specialty Gas & Equipment

a. Gases blended by MESA, then certified by Scott-Marrin.

6. PraxAir

12. Spectra Gases, Inc.

13. Applied Gas, Inc.

14. GTS-Welco

b. These could be gases produced by Praxair. However, GTS states their EPA Protocol Gases are 

produced at their production facility in Morrisville, PA, which is not a facility listed by Praxair.
