What This Cheat Sheet Covers (and What It Does Not)
This is a compressed, one-page-style review of the facts a Certified Professional in Industrial Stormwater Management candidate needs most: fees, format, eligibility, the eleven scope-of-practice domains and the regulatory context around the Multi-Sector General Permit (MSGP). It is built for quick scanning. For depth on any one area, follow the links to the longer guides on this site, starting with the CPISM Study Guide and the complete guide to all 11 content areas.
One honesty note up front: ECI has not published a numeric passing threshold, an exact question count or a pass rate that we could verify. Where this sheet lacks a number, it says so rather than guessing. Anyone offering you a precise cut score or percentage-by-domain table for this exam should be asked for a source.
Credential Snapshot: CPISM at a Glance

If you are still orienting yourself, the explainers What Is CPISM Certification? and What Does CPISM Stand For? cover the basics in plain language.
Fees and Registration Mechanics
The figures below come from ECI's September 2026 Program Fee Schedule, in USD. The order of operations matters: your application must be approved before you can schedule anything.
| Line item | Amount |
|---|---|
| Application (includes digital General Principles Review Manual) | $375 |
| Prometric CPISM examination package (Part A/Proctored Exam) | $195 |
| Application plus Prometric exam total | $570 |
| Prometric exam-only retest | $195 |
| First in-person examination and proctor | $210 |
| In-person retest and proctor | $190 |
| Optional ECI-sponsored in-person review | $400 |
| Annual full-certification renewal | $200 |
| Credit-card processing charge | 3.5% |
Independent-proctor charges are set by that proctor, not by ECI. Optional preparation and payment-processing charges sit on top of the $570 base total. For a fuller budget, including what to plan for beyond ECI's own fees, see the CPISM Certification Cost breakdown.
Exam Format: Part A, Part B and the Clock
Part A: open-book and untimed
Part A is described as the proctored examination component, and it is open-book and untimed. Because it allows references, the skill being tested is navigation: knowing where an answer lives in the permit text or review materials and reading precisely. Candidates who treat "open-book" as "no preparation needed" tend to waste time hunting for provisions they have never seen.
Part B: closed-book, 180 minutes
The full professional Part B examination is closed-book with a 180-minute limit, divided into two sections:
- Section 1 (60 minutes): fundamental knowledge.
- Section 2 (120 minutes): applied scenarios and calculations.
The practical component here is an examination section. It is not additional course hours and not a separately verified hands-on assessment. Expect the second section to reward candidates who can work a scenario from permit coverage through control measures, monitoring and corrective action, with arithmetic where required. This is also why an authorized calculator matters on exam day.
Key Takeaway
Budget your Part B clock deliberately: 60 minutes for fundamentals leaves little slack for lingering, and the 120-minute applied section is where scenario and calculation fluency pays off. Practice timed scenario work, not just recall.
Scoring and difficulty
ECI reports results as Pass/Fail. No numeric passing threshold, exact question count or published pass rate was verified, so be skeptical of any site quoting them. For what is and is not known, read CPISM Passing Score and CPISM Pass Rate: What the Data Shows, and for a candid view of difficulty, How Hard Is the CPISM Exam?
Delivery mode: confirm before you buy
There is a documented tension in ECI's own materials. The September 2026 fee schedule labels the Prometric packages as remote, while ECI's published examination-event guidance says test centers and in-person events are available and that remote examinations require case-by-case approval for extenuating circumstances. Confirm your approved delivery mode before purchasing, and follow the selected provider's approval and equipment instructions. Scheduling details are covered in CPISM Exam Dates.
Eligibility and Application Paperwork
- Baseline: high school diploma or GED.
- Experience and education: seven combined years of qualifying credit. A college degree is not mandatory.
- Education credit: qualifying education receives program credit; unrelated degrees receive half credit. Documentation is required.
- References: the January 2024 application checklist requires four professional references, ordinarily no more than two from the same company, preferably including an ECI-certified professional. The current FAQ permits municipal employees to enter two references twice.
- Documentation: education and relevant employment documentation must accompany the application.
- Sequence: application approval comes before scheduling. Review training is optional.
The practical point: start collecting reference contacts and employment documentation early, because delays in paperwork, not study time, are what usually push back a testing date. The full qualification walkthrough is in CPISM Requirements: Eligibility, Prerequisites & How to Qualify.
The Eleven Scope-of-Practice Domains in One Pass
The eleven domain headings below come from ECI's CPISM Scope of Practice, Update 2017 Rev.01.1. They are historical, unweighted competency headings used here as preparation categories. They are not a newly issued 2026 blueprint, not a confirmed exhaustive list of current exam coverage, and not tied to official percentage allocations. The scope document's Job Task Analysis successor (V1.01, 11-5-19) could not be retrieved, so its alignment with the delivered exam is unverified.
Domain 1: Coverage Under the MSGP
Know who needs permit coverage and who is eligible under it.
- Which industrial activities trigger coverage
- Eligibility conditions and limits on coverage
- Notice and authorization concepts
Domain 2: Control Measures and Effluent Limits
The core of pollution prevention: what you must do and what you may not exceed.
- Non-numeric technology-based and numeric effluent limitations
- Good housekeeping, maintenance and spill-prevention concepts
- Matching a control measure to a pollutant source
Domain 3: Corrective Actions
What the facility must do when conditions or results show a problem.
- Triggering conditions and required response
- Documenting root cause and the fix
- Distinguishing a violation from a trigger for review
Domain 4: Inspections
Routine and other facility inspections as a compliance tool.
- Who inspects and what must be recorded
- Frequency concepts and documentation
Domain 5: Stormwater Pollution Prevention Plan (SWPPP)
The facility's governing document.
- Required contents and site description
- Identifying potential pollutant sources and outfalls
- Keeping the plan current as operations change
Domain 6: Monitoring
Sampling, testing and interpreting results.
- Discharge sources, outfall locations and sampling points
- Appropriate sampling and testing procedures
- Benchmark and result evaluation concepts
Domain 7: Reporting and Recordkeeping
Proving compliance on paper.
- What must be submitted and what must be retained
- Deadlines and record-retention logic
Domain 8: Special Requirements
Conditions that apply beyond the standard permit provisions.
- Situations with added or modified obligations
- How special requirements interact with the SWPPP
Domain 9: Sector-Specific Requirements
Industrial sectors carry their own provisions.
- Knowing which sector's rules apply to a facility
- Sector provisions layered on general requirements
Domain 10: State Tribal Requirements
Where state or tribal conditions modify the federal baseline.
- Recognizing when local conditions override or add to the base permit
Domain 11: Permanent Water Quality BMP Design and Hydrology
The engineering-flavored domain and likeliest source of calculations.
- Hydrology basics that drive BMP sizing
- Design elements for mitigation and permanent controls
- Linking runoff volume and pollutant load to a design choice
For a domain-by-domain breakdown with study angles, see the CPISM Exam Domains guide.
Concepts the Current ECI Overview Adds
ECI's current CPISM overview separately lists supported concepts. They are not merged here into an invented blueprint, but they are useful review prompts alongside the eleven domains:
- Permit coverage guidelines and requirements
- Eligibility under the permit
- Compliance, violations and corrective action measures
- Effluent and pollutant control measures and limitations
- Discharge sources, outfall locations and monitoring
- Appropriate sampling and testing procedures
- Maintenance and good housekeeping
- Mitigation design elements
- Development of BMP measures to reduce and prevent industrial stormwater discharges
- Preparing SWPPP and monitoring programs
- Post Construction BMPs and Lid Methods (spelling as printed in the overview)
Notice the overlap: permit coverage, control measures, corrective action, sampling, SWPPP development and BMP design all recur across the two lists. Those recurring themes are the safest places to concentrate your effort.
MSGP Status: What Changed in 2026
EPA states that its 2021 MSGP expired on February 28, 2026 and is administratively continued for operators already covered before expiration. That is regulatory context. It is not evidence that ECI has issued an updated exam version, and it does not describe coverage for new operators.
Sequencing Your Review by Domain
Because the scope is unweighted, sequence by dependency rather than by guessed importance. This is the only structured-plan section in this sheet, and it is built around the CPISM's own logic:
Coverage and limits
- Domains 1 and 2: coverage, eligibility, control measures, effluent limits
- Skim the General Principles Review Manual included with your application
The compliance loop
- Domains 3 and 4: corrective actions and inspections
- Trace one scenario from inspection finding to documented fix
Plan and data
- Domains 5, 6 and 7: SWPPP, monitoring, reporting and recordkeeping
- Practice sampling-point and outfall questions
Variations and calculations
- Domains 8, 9 and 10: special, sector-specific and state/tribal requirements
- Domain 11: hydrology and BMP design calculations with your authorized calculator
Timed integration
- Run a 60-minute fundamentals block and a 120-minute scenario block back to back
- Use the CPISM practice tests to find weak domains
Why this order: the compliance loop in Weeks 1 to 3 is what Section 2 scenarios chain together, so learning it in sequence makes applied questions feel familiar. Domain 11 goes late because calculations demand the conceptual vocabulary from earlier weeks. A fuller approach is in the CPISM Study Guide.
Exam-Day and Renewal Checklist
Before you sit
- Application approved; exam scheduled through Prometric or an ECI-approved event.
- Delivery mode confirmed in writing (remote versus test center or in-person event).
- Government photo identification ready.
- Authorized calculator with no internet, camera or recording capability.
- Provider equipment and approval instructions reviewed.
- Portal charge verified, remembering the 3.5% credit-card processing charge.
After you pass
- Complete eight professional development hours each year.
- Pay the $200 annual renewal.
- Keep records of PDH activities in case documentation is requested.
If you are weighing whether the investment makes sense for your career, these resources provide context: Is the CPISM Certification Worth It?, the CPISM Salary Guide and CPISM Jobs. In general terms, the credential is aimed at people who manage permit compliance, SWPPPs, monitoring and corrective action for industrial facilities, along with consultants and municipal staff who oversee them.
Key Takeaway
The most common avoidable mistakes are administrative: unapproved delivery mode, an unauthorized calculator, or a missing reference. Resolve them before you study your last domain, not after.
Frequently Asked Questions

ECI reports results as Pass/Fail, and no numeric passing threshold, exact question count or pass rate was verified. Treat any specific cut score you see online with caution. More context is in CPISM Passing Score.
No. You need a high school diploma or GED plus seven combined years of qualifying experience and education credit. Qualifying education earns program credit, and unrelated degrees receive half credit, with documentation required. Read the requirements guide for specifics.
Not necessarily. They come from the 2017 Scope of Practice update and are unweighted preparation headings. The newer Job Task Analysis document could not be retrieved, so current blueprint alignment is unverified. Pair them with ECI's current overview concepts and check the official sources, then practice with the CPISM practice exams.
Keep this sheet handy as a quick reference, and return to the linked guides whenever a single topic needs more depth. Verify fees, delivery mode and permit references against ECI and EPA before you commit money or time.
