Monsanto has instituted a Leak Detection and Repair (LDAR) program to monitor and repair over 15,000 valves and flanges. The acceptable leak rate was reduced from 10,000 ppmv to 500 ppmv.
The LDAR system has reduced emissions of VOCs by almost 300,000 pounds a year.

The reduced emissions result in reduced losses of products and raw materials. The program itself costs approximately $150,000 a year to implement.
