The industrial pretreatment program received its approval from the Environmental Protection Agency (EPA) Region Ill on June 18, 1984. At that time a total of eight (8) industries were permitted. Since that time, the program has grown and includes permitting of septic haulers, restaurants and super markets. As the year 2002 began, permits have been issued to:
- 26 industries
- 11 septic haulers
- 50 restaurants
- 5 super markets
The delivery of liquid biosolids and sludges have also been approved through the pretreatment program as long as they meet the Pennsylvania Department of Environmental Protections Chapter 271, Table 3 - Pollutant Concentrations and do not contain filamentous bacteria.
