The history of this facility dates back to the late 19th century. A facility capable of producing 180 kg/day methylphosphonyldichloride (DC), a sarin precursor, was installed during the period 1965 to 1968. Some small scale production, approximately 600 kg appears to have been undertaken in the period 1969 to 1970 in support of a sarin trial production run at the Potoci facility over the same period. A more substantial production run over the period 1988 to 1989 produced 40 metric tons of methylphosphonyldichloride (DC) that was shipped to Potoci for use in a sarin production campaign. However, the sarin was not produced, and when the MTI operation in Potoci was abandoned, all 40 metric tons were returned to the Miloje Blagojevic facility. It is probable that other unused chemicals held at the Potoci facility were also sent to Lucani along with the DC, but this is not clearly indicated. These other chemicals were 5 metric tons of isopropyl alcohol, 5 metric tons of methylene dichloride, 10 metric tons of sodium-silicofluoride, and 3 metric tons of sulfur monochloride. 
One report suggests that this facility engaged in the production of mustard (HD) and sarin (GB) beginning in 1989 and continuing up to the early to mid-1990s. However, this report is unreliable, and the balance of evidence suggests that no additional production took place after 1990.
