APWA Certified Stormwater Manager (CSM)
Exam Practice Questions (three major exam
domains)
DOMAIN 1: PROGRAM MANAGEMENT
(Overall Stormwater Management, Program Administration,
Communication/Education, Planning and Design)
1. Which federal act serves as the primary legal foundation for stormwater
regulation in the United States? A) Clean Air Act B) Safe Drinking Water Act C)
Clean Water Act (correct answer) D) Resource Conservation and Recovery Act
Rationale: The Clean Water Act (CWA), originally the Federal Water Pollution
Control Act of 1972, establishes the regulatory framework for controlling pollutant
discharges into U.S. waters, including the National Pollutant Discharge
Elimination System (NPDES) stormwater permits.
2. Under the NPDES program, Municipal Separate Storm Sewer Systems
(MS4s) are classified into how many categories? A) Two B) Three C) Two main
categories with sub-classifications (correct answer) D) Five
Rationale: MS4s are primarily classified as Phase I (large and medium cities,
generally serving populations over 100,000) and Phase II (smaller regulated
MS4s). The classification determines the specific permit requirements and
compliance deadlines.
3. What is the minimum control measure required for all regulated small MS4s
under the Phase II stormwater regulations? A) Industrial stormwater monitoring
B) Public Education and Outreach (correct answer) C) Construction site
erosion control only D) Post-construction stormwater management for all sites
Generated by Kimi.ai
,Rationale: The EPA’s Phase II rule requires all regulated small MS4s to
implement six minimum control measures (MCMs). Public Education and
Outreach is the first MCM and is mandatory for all regulated MS4s, regardless of
size.
4. A stormwater manager is developing an intergovernmental agreement for
shared stormwater services. Which of the following is the most critical element to
include? A) Fixed pricing for 50 years B) Clearly defined roles,
responsibilities, and liability provisions (correct answer) C) Automatic
renewal clauses only D) Exclusion of public participation requirements
Rationale: Intergovernmental agreements must clearly delineate responsibilities,
cost-sharing mechanisms, performance standards, and liability provisions to
ensure effective shared stormwater management and legal protection for all
parties.
5. Which of the following best describes the concept of “watershed-based
stormwater management”? A) Managing stormwater only at the property level B)
Coordinating stormwater management across jurisdictional boundaries
within a hydrologic unit (correct answer) C) Focusing exclusively on flood
control D) Eliminating all stormwater discharges
Rationale: Watershed-based management recognizes that stormwater flows
across political boundaries. It integrates planning, implementation, and
monitoring across the entire watershed to achieve water quality and quantity
goals more effectively than parcel-by-parcel approaches.
6. What is the primary purpose of a Stormwater Utility Fee? A) Generate general
fund revenue for the municipality B) Establish a dedicated, equitable funding
source for stormwater management programs (correct answer) C) Replace
property taxes entirely D) Fund only new capital construction projects
Rationale: Stormwater utility fees create a dedicated revenue stream based on
impervious area (a direct indicator of runoff contribution), ensuring that those who
Generated by Kimi.ai
,contribute more to stormwater problems pay proportionally more for
management.
7. In program administration, what does the acronym “CMOM” stand for? A)
Capital Management and Operations Manual B) Capacity, Management,
Operations, and Maintenance (correct answer) C) Comprehensive Municipal
Ordinance Manual D) Certified Municipal Operations Manager
Rationale: CMOM is an EPA framework for sanitary sewer systems but is
increasingly applied to stormwater programs. It focuses on ensuring adequate
capacity, proper management, effective operations, and proactive maintenance
of infrastructure.
8. Which of the following is NOT typically considered a stakeholder in municipal
stormwater management? A) Local environmental groups B) Developers and
builders C) State regulatory agencies D) Federal aviation authorities (unless
airport runoff is involved) (correct answer)
Rationale: While federal aviation authorities may be involved in airport-specific
stormwater issues, they are not typically core stakeholders in general municipal
stormwater programs. Core stakeholders include residents, businesses,
environmental groups, developers, and regulatory agencies.
9. A stormwater manager needs to communicate technical information about
TMDL implementation to elected officials. Which approach is most effective? A)
Provide detailed hydraulic calculations B) Translate technical data into
economic impacts, public benefits, and visual aids (correct answer) C) Use
only engineering jargon to maintain credibility D) Avoid discussing costs entirely
Rationale: Effective communication with non-technical decision-makers requires
translating complex technical information into understandable concepts, focusing
on economic implications, public benefits, risks, and using visual aids like maps
and graphics.

, 10. What is the primary advantage of implementing a Stormwater Master Plan?
A) It eliminates the need for NPDES permits B) It provides a comprehensive,
long-term framework for managing stormwater quality and quantity (correct
answer) C) It guarantees federal funding for all projects D) It removes the need
for public participation
Rationale: A Stormwater Master Plan integrates water quality, quantity, and
infrastructure needs into a comprehensive strategy. It guides capital
improvement programming, regulatory compliance, and prioritization of resources
over a multi-year horizon.
11. Which document outlines the specific tasks, responsibilities, and measurable
goals for a stormwater management program? A) NPDES Permit B) Stormwater
Management Program (SWMP) Document (correct answer) C) General Plan
D) Zoning Ordinance
Rationale: The SWMP is the operational document that details how a regulated
MS4 will implement the six minimum control measures, including measurable
goals, responsible parties, schedules, and tracking mechanisms required by the
NPDES permit.
12. In the context of stormwater public education, what does “social marketing”
refer to? A) Advertising on social media only B) Using marketing principles to
influence behaviors that benefit the watershed (correct answer) C) Selling
stormwater products to the public D) Political campaigning for stormwater fees
Rationale: Social marketing applies commercial marketing strategies to change
behaviors for social good. In stormwater, it targets behaviors like proper pet
waste disposal, responsible fertilizer use, and car washing practices to reduce
pollutant loading.
13. Which of the following is a key component of an effective illicit discharge
detection and elimination (IDDE) program? A) Eliminating all storm drain outfalls
B) Outfall mapping, dry weather screening, and source tracing (correct
