ARMORED OUTFALLS ................................................................................................................................ 10 <br />This control structures system is designed to be implemented as part of a storm water pollution prevention plan <br />(SW3P) prepared specifically for a site under the EPA General Permit for Discharge of Storm Water Associated <br />with Industrial Activities or the EPA Multi-Sector General Permit (MSGP). It is generally compatible with various <br />state general permits for Wyoming, Colorado, Nebraska and South Dakota, for both industrial and construction <br />activities, but some amendment may be necessary. This structure system is limited to implementation of structural <br />best management practices (BMP) within an existing plan. The developer of this plan makes no warranty or claim <br />of completeness. This is not intended to replace the proper design of any structures, and building codes and other <br />regulatory issues should be taken into account by any person using this system. <br />INTRODUCTION <br />This system provides details suitable for permitting and construction use of the most common structural BMP used <br />at industrial and construction sites such as quarries, sand and gravel pits, ready mix plants, asphalt plants, <br />construction sites, and similar operations. <br />If specific structures are to be constructed according to the SW3P, this system and the applicable type number <br />should be cited in the plan. When using these, the plan(s) for a site should specify which type of structure is to be <br />placed at as precise a location as possible, indicating any key dimensions, elevations, or other data necessary to <br />allow the person(s) implementing the plan to construct and evaluate the structure, and allowing inspectors to <br />determine if the intent has been carried out. <br />D~N~ <br />P ~ Ll~ ~R ~ F/~~ <br />SITS. ~ zpa,_o~pY <br />0 <br />~~h rj~ <br />0 <br />h <br />R~eived <br />BAR 2 6 ?001 <br />DiviBron o f ~o e ra~s 8 Gep o9 <br />Y <br />EQ-OS Surface Water Plan Supplement MAR 2001 (REV) <br />STORM WATER CONTOL STRUCTURES SYSTEM Page STR-I ©2001 Wasteline, inc. <br />
