The California Qualified SWPPP Practitioner (QSP) Certification Exam is a highly rigorous,
state-mandated evaluation administered to ensure storm water management professionals
possess the technical and regulatory competence required to enforce the State Water
Resources Control Board (SWRCB) Construction General Permit (CGP). Operating under strict
California environmental statutes, this practice exam tests your application-level mastery of
water quality monitoring, field sampling protocols, erosion and sediment control BMP
implementations, and compliance inspections. Rather than simple vocabulary recall, this
package challenges your analytical judgment regarding Risk Level 1, 2, and 3 site mandates,
Numeric Action Level (NAL) exceedances, and Corrective Action reporting timelines.
Mastering these complex, scenario-based challenges ensures you build the problem-solving
stamina required to secure your professional registration on the first attempt.
Core Domains Tested
1. California Regulatory Framework and CGP Permit Overview (20%): Focuses on the
role of the QSP vs. QSD, Legally Responsible Person (LRP) requirements, SMARTS
system logging, and Risk Determination architecture.
2. Erosion and Sediment Control BMPs (30%): Details structural and non-structural
Best Management Practices (BMPs), perimeter controls, active vs. passive treatment
systems, and stabilization thresholds.
3. Site Inspection, Monitoring, and Sampling Protocols (30%): Covers Visual
Inspections (pre-, during, and post-storm), collecting and analyzing field grab samples
for pH and Turbidity, and instrument calibration.
4. Exceedances, Reporting, and Corrective Actions (20%): Emphasizes evaluating
Numeric Action Levels (NALs), filing Water Quality Based Corrective Action Reports,
and managing non-visible pollutant event logs.

QUESTIONS 1-100
Q1: During a regular weekly site inspection on a Risk Level 2
construction project in the Sacramento Valley, a QSP notices that a
segment of the perimeter silt fence has buckled under an
accumulation of sediment that has reached exactly half the structural
height of the barrier. According to California Construction General
Permit standards, what is the correct operational interpretation and
required maintenance timeline?
A) The BMP is functioning perfectly because it is trapping sediment;
document the observation and re-inspect in 14 days.
B) The barrier has reached its maximum allowable sediment
accumulation threshold; the QSP must log the maintenance need
and ensure it is repaired or cleared within 72 hours of discovery.
C) Immediately halt all active grading operations across the entire site
and file an emergency alert via the SMARTS system.
D) Remove the silt fence entirely and replace it with un-anchored
straw wattles before the next operational shift.
Rationale: The correct answer is B because the California
Construction General Permit (CGP) mandates that sediment must be
removed from sediment barriers (such as silt fences) when it reaches
a maximum of one-third to one-half of the barrier's height.
Furthermore, the permit requires that once a structural BMP defect
or maintenance need is identified during an inspection, repairs or
maintenance must be initiated immediately and completed within 72
hours. Option A is incorrect because delaying action for 14 days
violates the permit compliance timeline. Option C describes an
excessive reaction not required for a standard localized barrier
maintenance item. Option D is incorrect because replacing a
perimeter control with un-anchored wattles is a structural failure that
creates an illegal, non-compliant perimeter control setup.

Q2: A QSP is preparing for a predicted rain event on a Risk Level 3
construction site. Weather forecasts via the National Weather Service
indicate a 75% probability of a Qualifying Rain Event (defined as
producing 0.5 inches or more of precipitation). According to the CGP,
what specialized document must the QSP develop and deploy on-site
before the storm arrives?
A) A Water Quality Based Correction Manifesto (WQBCM)
B) A Rain Event Action Plan (REAP) designed for the specific phase
of construction
C) A updated Notice of Intent (NOI) signed by the Legally Responsible
Person
D) A Passive Treatment System (PTS) chemical injection log
Rationale: The correct answer is B. For Risk Level 2 and Risk Level 3
traditional construction sites under the California CGP, the QSP is
legally required to develop a project-and-phase-specific Rain Event
Action Plan (REAP) at least 48 hours prior to any forecast event with a
50% or greater probability of producing 0.5 inches or more of rain.
Option A is a fabricated term. Option C is an administrative document
managed primarily by the Qualified SWPPP Developer (QSD) and filed
by the LRP, not a pre-storm operational plan. Option D is only
required if an active chemical dosing system is deployed on-site.
Q3: While collecting stormwater discharge grab samples from a Risk
Level 2 site outfall during a qualifying rain event, a QSP performs field
analytical testing. The field meter indicates a discharge pH value of
5.8 and a turbidity value of 350 NTU. What structural regulatory
thresholds have these values breached, and what is the required
reporting protocol?
A) They have exceeded an absolute Maximum Daily Limitation; the
site must immediately pay a direct fine via SMARTS.
B) They are within normal parameters for California soils; no
, 4
regulatory tracking is required.
C) They have breached the Numeric Action Levels (NALs) of pH < 6.5
and Turbidity > 250 NTU; the QSP must notify the LRP to ensure an
NAL Exceedance Report is submitted within 10 days of the
conclusion of the storm event.
D) They indicate a failure of the regional wastewater treatment plant;
the QSP must notify the local municipality within 24 hours.
Rationale: The correct answer is C. The California CGP establishes
Numeric Action Levels (NALs) for Risk Level 2 and Risk Level 3 sites.
The daily average NAL for pH must be between 6.5 and 8.5, and the
daily average NAL for turbidity is 250 NTU. A pH of 5.8 (acidic) and a
turbidity of 350 NTU constitute explicit NAL exceedances, triggering
an evaluation of the site's BMPs and requiring an official report via
SMARTS within 10 days of the storm's end. Options A, B, and D
mischaracterize the regulatory category, the values, or the
enforcement reporting pathways.
Q4: A QSP is instructing a field technician on the proper collection
techniques for storm water grab samples. To ensure that the sample
is legally valid and scientifically representative of the site's actual
sheet-flow discharge, where and how should the sample container be
filled?
A) Collected from a stagnant, stagnant puddle located near the
center of the interior staging area.
B) Skimmed lightly off the very top layer of a sediment basin to
capture floating foam.
C) Collected at a designated discharge outfall point where
stormwater actively exits the site boundary, dipping the bottle
directly into the center of the turbulent, flowing water stream
without disturbing bed sediments.
D) Filled using a garden hose connected to a water truck to simulate
