Management Plan.
5. The Stormwater Pollution Prevention Plan is abbreviated as:
A) SPCC
B) ESCP
C) SWPPP
D) SWMP
Answer: C) SWPPP
Rationale: SWPPP is the correct abbreviation for Stormwater Pollution Prevention
Plan. This is a required document for many construction and industrial activities

A) How the BMP functions
B) The pollutants it targets
C) The BMP and its general purpose
D) Areas where the BMP should be used
Answer: C) The BMP and its general purpose
Rationale: The Description and Purpose section defines the BMP and its general
purpose, providing an overview of what the BMP is and why it would be used.
9. What does the "Objectives" section of a BMP document list?
A) Areas where BMP should not be used
B) How the BMP functions
C) Items to look for during inspections
D) Maintenance requirements
Answer: B) How the BMP functions
Rationale: The Objectives section lists how the BMP functions, explaining the
mechanisms by which the BMP achieves its intended purpose.
10. The "Targeted Pollutants" section of a BMP document identifies:
