This control structures system is designed to be implemented as part of a storm water pollution prevention plan
(SW3P) prepared specifically for a site under the EPA General Permit for Discharge of Storm Water Associated
with Industrial Activities or the EPA Multi-Sector General Permit (MSGP). It is generally compatible with various
state general permits for Wyoming, Colorado, Nebraska and South Dakota, for both industrial and construction
activities, but some amendment may be necessary. This structure system is limited to implementation of structural
best management practices (BMP) within an existing plan. The developer of this plan makes no warranty or claim
of completeness. This is not intended to replace the proper design of any structures, and building codes and other
regulatory issues should be taken into account by any person using this system.
INTRODUCTION
This system provides details suitable for permitting and construction use of the most common structural BMP used
at industrial and construction sites such as quarries, sand and gravel pits, ready mix plants, asphalt plants,
construction sites, and similar operations.
If specific structures are to be constructed according to the SW3P, this system and the applicable type number
should be cited in the plan. When using these, the plan(s) for a site should specify which type of structure is to be
placed at as precise a location as possible, indicating any key dimensions, elevations, or other data necessary to
allow the person(s) implementing the plan to construct and evaluate the structure, and allowing inspectors to
determine if the intent has been carried out.
