Storm Water Pollution Prevention Plans
Development and Oversight

Pursuant to California's Construction General Permit, planned construction activity that will result in a land disturbance of one acre or more may only proceed upon the approval and implementation of a site-specific Storm Water Pollution Prevention Plan (SWPPP)--with relatively few exceptions.

The level of effort and cost associated with developing and implementing a custom SWPPP is dependent upon the scope of the project and its General Permit category.  A construction project is categorized by the General Permit as either a traditional project or a linear underground/overhead (utility) project (LUP). Both categories are further subdivided by three.  The subcategories for traditional projects are identified as risk level.  For LUPs, they are identified by type.  Risk Level 1/Type 1 projects have the least amount of General Permit requirements, where as Risk Level 3/Type 3 projects have the most.

Water Pollution Control Plans

When a project is not subject to the General Permit, some entities or project owners may still require at least a minimal plan to guard against water pollution.  Such is the case with Caltrans, which requires a Water Pollution Control Plan (WPCP) for projects under one acre.

A SWPPP must be developed by a Qualified
SWPPP Developer (QSD), and it must be
implemented and overseen by a Qualified
SWPPP Practitioner (QSP) or a QSD in order
to satisfy the requirements of the California
Construction General Permit.
