WPC Permits main page Water Pollution Control Program Permits One of Water Pollution Control's key activities is the issuance of permits to build, erect, alter, replace, operate, use or maintain existing point sources of water pollution. The majority of our permits are for the discharge of treated wastewater from domestic and industrial facilities. We also issue permits for land application of wastes from domestic, industrial and agricultural facilities. Our permits usually specify requirements for regular sampling of wastewater at the discharge points. In the case of land application, the permit specifies the methods by which wastes are handled and disposed.
Permits also specify water quality standards for any discharges.
Most of these permits are written to be site-specific to reflect the unique nature of the waste water stream or the receiving stream. These permits usually have a five year cycle. As a permit expires, it is re-drafted, modified if needed, then placed on public notice for 30 days. When on public notice, a draft permit is open for comments. A group of permits are processed for public notice every two weeks.
