CERTIFICATION EXAM OFFERED BY
ENVIROCERT INTERNATIONAL, INC |
COMPLETE EXAM Q&A WITH RATIONALES
1. Which federal law establishes the framework for
regulating discharges of pollutants into waters of the
United States, including stormwater from
construction activities?
A) Resource Conservation and Recovery Act (RCRA)
B) Clean Water Act (CWA)
C) Comprehensive Environmental Response,
Compensation and Liability Act (CERCLA)
D) Safe Drinking Water Act (SDWA)
Correct answer: B
Rationale: The Clean Water Act, particularly Section
402 (NPDES), regulates stormwater discharges from
construction and industrial activities through the
National Pollutant Discharge Elimination System
permit program .
2. A CPESC is recognized by the US EPA as qualified
to prepare which of the following documents?
,A) Environmental Impact Statement (EIS)
B) Stormwater Pollution Prevention Plan (SWPPP)
C) Phase I Environmental Site Assessment
D) Hazardous Waste Management Plan
Correct answer: B
Rationale: CPESC is the only professional
certification recognized by the EPA whose
professionals are designated as qualified to prepare
Stormwater Pollution Prevention Plans (SWPPPs) .
3. Which equation is commonly used to predict
annual soil loss from sheet and rill erosion on
construction sites?
A) Rational Method
B) Manning's Equation
C) Revised Universal Soil Loss Equation (RUSLE)
D) Bernoulli's Principle
Correct answer: C
Rationale: The Revised Universal Soil Loss Equation
(RUSLE) is the standard erosion prediction model
used to calculate average annual soil loss from sheet
and rill erosion, expressed as A = R × K × LS × C × P .
,4. What does the "K" factor represent in the Revised
Universal Soil Loss Equation (RUSLE)?
A) Rainfall erosivity
B) Soil erodibility
C) Slope length and steepness
D) Cover management
Correct answer: B
Rationale: The K factor represents soil erodibility,
which is a measure of a soil's susceptibility to erosion
based on its physical properties including texture,
organic matter, and permeability .
5. The "R" factor in RUSLE accounts for which
erosive force?
A) Wind velocity
B) Slope gradient
C) Rainfall and runoff erosivity
D) Soil compaction
Correct answer: C
Rationale: The R factor represents rainfall and runoff
erosivity, calculated from long-term rainfall records
including intensity, duration, and kinetic energy of
storm events .
, 6. Which soil texture is generally considered the most
erodible?
A) High portion of clay
B) High portion of organic matter
C) High portion of silt and very fine sand
D) High portion of stone
Correct answer: C
Rationale: Soils with high portions of silt and very fine
sand are generally the most erodible because these
particles are easily detached and transported by
both wind and water .
7. According to the CPESC examination blueprint,
which topic carries the highest percentage weight at
16-20%?
A) Site Assessment and Resource Inventory
B) Specification of Pollution Prevention Measures
C) Rules and Regulations
D) Plant Species Selection
Correct answer: B
Rationale: Specification of Pollution Prevention
Measures carries the highest weight at 16-20%,
