Inc. • • Page 10 <br />Aggrcgatc Production Facility stormwater Management Plan <br />waters are directed away from the facility and potential pollutants and eventually flow <br />into the sedimentation pond. <br />3.b.2.2 Materials Handling and Spill Prevention <br />Specific management practices employed at the New Thornton facility intended to <br />reduce the potential for contamination of stormwater which contacts "significant" <br />materials are presented on Section 3 -Form A. <br />3.b.2.3 Sediment and Erosion Prevention <br />The majority of the plant site consists of loose and/or compacted sand and gravel soil <br />substrate. As a result, sediment and erosion control are of concern for stormwater <br />management. However, the pit is the ultimate collection point for all sediment eroded <br />from the property. It does not leave the property and will likely be excavated at some <br />later date. <br />Partial natural revegetation is occurring on soil and aggregate piles around the <br />periphery of the disturbed area. <br />3.b.2.4 Other Pollution Prevention Measures <br />In order to prevent possible contamination of stormwater, the stormwater <br />Management Plan Administrators (identified in Section 3.a) have implemented a <br />procedure for the cleanup and removal of all non-essential and discarded equipment, <br />as well as chemicals and chernical storage containers from the site. In addition, <br />steps are being taken to relocate lubricating fluid containers within containment <br />vessels of appropriate holding capacity for both raw product and contact stormwater. <br />3.c Existing Discharge Sampling Data <br />No known stormwater discharge sampling data has been collected. <br />3.d Preventative Maintenance <br />A preventative maintenance program has been established for the New Thornton <br />facility which includes inspection and maintenance of stormwater management <br />devices as well as inspection and testing of plant equipment and operational <br />systems. These inspections are intended to uncover conditions which could <br />potentially lead to breakdowns or failures that result in discharge of pollutants to <br />storm sewers or surface waters. <br />
