MMD Enterprise Inc.  Katy, Texas 
Our facility has two 8000 gallon storage tanks, one 6000 gallon storage tank, and one 12000 gallon storage tank and equipment for receiving ammonia from truck transports and railcars.  It is our policy to meet, or exceed, all local, state, and national standards relating to storing and transferring ammonia. 
Although ammonia is a toxic material, records at this facility show that we have never had any accidents or releases with off-site consequences.  Specific safety features that we employ to minimize damage from any unusual occurrences include: 
1. Excess flow valves to prevent flow from the tank if any hose or line breaks. 
2. Pressure relief valves on each tank to prevent overpressuring and rupture of the tanks. 
3. The ammonia storage tanks and piping are barricaded to prevent inadvertent contact by automobiles. 
To further ensure safe operation of the facility, our employees are trained, and periodically retrained, in procedures t 
hat are in accord with current ammonia storage and transferring regulations.  In addition, we have coordinated with the Katy Volunteer Fire Department to respond to emergencies. 
As required by the EPA, we have analyzed the worst-case release scenario defined by the EPA. This scenario involves a vapor cloud release of the entire contents of the 12,000 gallon tank.  According to information supplied by the EPA the impact from this scenario would extend 2.70 miles from our facility.  There was one school affected by the release. 
It is extremely unlikely that an event such as EPA's worst-case release scenario will ever occur.  A more probable, but still highly unlikely event, would be an event like a hose break caused by a pull away. According to information supplied by the EPA, the impact from such a release would only extend 0.15 miles and would not impact any schools, hospitals, or parks.
