DRAFT <br />1.5 Pollution Source Identification and Assessment <br />The second step in the development of a SWPPP is to identify and assess potential sources <br />at the site which may reasonably be expected to contribute significant amounts of <br />pollutants to storm water discharges including discharges of pollutants from non -storm <br />water sources. The potential sources of storm water pollution are identified by conducting a <br />materials inventory, evaluating past spills and leaks, identifying any non -storm water <br />discharges and/or illicit connections to the site's storm water conveyances, and evaluating <br />existing storm water quality data. This assessment provides a risk-based approach by <br />assisting in targeting the most important pollutant sources for corrective and/or preventive <br />action. <br />A description of the site (see Section 3: Table 1: General Information) and a site map were <br />prepared (see Section 5: Appendisces) based on information obtained from the review of <br />site documents and the site reconnaissance. Potential pollutant sources identified at the <br />site, and possible routes of storm water exposure to the identified pollutant sources, are <br />summarized below: <br />C:\TEMP\SMPREV2.doc Section I-8 <br />
