PCS-ICIS Overview

PCS and ICIS Banner
PCS and ICIS icon

The Permit Compliance System (PCS) and Integrated Compliance Information System (ICIS) databases provide information on companies which have been issued permits to discharge wastewater into rivers. You can review information on when a permit was issued and expires, how much the company is permitted to discharge, and the actual monitoring data showing what the company has discharged. The PCS-ICIS Search allows you to retrieve preselected data from the PCS and ICIS databases in Envirofacts. You can narrow your search by selecting various options including facility name, geographic location, facility industrial classification, and chemicals.

You may also use the PCS-ICIS Customized Search to retrieve data and design a search for your particular needs, using any data element available from the Envirofacts Warehouse. Customized searches are primarily geared toward more experienced users.

The search is highly dependent on geography. Currently all states are reporting to ICIS, except for Wyoming. Wyoming data will begin flowing data to ICIS-NPDES as soon as February or March of 2013.
