1.0 Executive Introduction: The Scope of the Grade 4
Manager
The transition from the Grade 3 supervisor level to the Grade 4 manager level represents the
most significant paradigm shift in the California Water Environment Association (CWEA)
certification hierarchy. While the lower grades focus heavily on the mechanical execution of
maintenance tasks, equipment operation, and direct crew supervision, the Grade 4 certification
is fundamentally an examination of administrative competency, strategic foresight, and
regulatory liability management. The Grade 4 candidate is no longer merely responsible for
clearing a stoppage; they are responsible for the legal defense of the agency following a
catastrophic sanitary sewer overflow (SSO), the long-term financial solvency of the enterprise
fund through compliance with GASB 34, and the rigorous adherence to due process in
personnel actions.
This comprehensive report serves as both a high-level practice examination and a deep-dive
research document. It is structured to replicate the intensity and breadth of the actual exam,
with 55 scenarios that test the limits of a candidate's knowledge regarding the State Water
,Resources Control Board (SWRCB) Statewide General Waste Discharge Requirements
(WDRs), specifically the transition to the new Order WQ 2022-0103-DWQ. Furthermore, it
integrates complex management theories, from Life Cycle Costing (LCC) to the Skelly hearing
process, ensuring that the candidate is prepared not just to pass a test, but to lead a modern
wastewater utility.
2.0 Module I: Advanced Regulatory Compliance
Focus: SWRCB Order WQ 2022-0103-DWQ, Reporting Timelines, Legal Authority, and the
SSMP.
2.1 The Regulatory Paradigm Shift
The most critical knowledge gap for current candidates is the migration from the longstanding
Order 2006-0003-DWQ to the active Order WQ 2022-0103-DWQ. Effective June 5, 2023, the
new Order replaced the previous regulations, introducing stricter definitions for "Waters of the
State," new reporting categories (Category 4), and enhanced resiliency requirements. The
following scenarios rigorously test the application of these new rules.
Exam Scenarios 1–15
Question 1: Jurisdictional Scope of the General Order
Scenario: You are the newly appointed Collections Superintendent for a mid-sized sanitary
district. During a briefing with the General Manager regarding the implementation of the new
Sewer System Management Plan (SSMP), a question arises regarding the regulatory reach of
the new Statewide General Order WQ 2022-0103-DWQ compared to the previous Order.
Specifically, the General Manager asks how the definition of protected waters has evolved and
what liability this creates for the District regarding spills that do not reach navigable rivers.
Which of the following statements accurately reflects the expanded scope of protection under
the 2022 Order?
A. The new Order restricts regulatory oversight strictly to "Waters of the United States" to align
perfectly with the federal Clean Water Act, thereby reducing state-level reporting for ephemeral
streams. B. The Order expands the definition of a spill to include any release from a private
lateral, regardless of volume, making the public agency financially liable for all private plumbing
failures. C. The Order emphasizes the protection of "Waters of the State," which includes both
surface waters and groundwater, thereby broadening the liability beyond the federal "Waters of
the US" definition and addressing pathways to groundwater. D. The Order removes the
requirement for reporting spills of less than 1,000 gallons if they are fully captured and returned
to the system, focusing resources only on catastrophic failures.
Executive Analysis: The correct assessment is C. The distinction between "Waters of the
United States" (WOTUS) and "Waters of the State" is the pivot point of modern environmental
compliance in California. Under the previous regulatory regime, there was often ambiguity
regarding spills that discharged to dry washes or infiltration basins. However, Order WQ
2022-0103-DWQ explicitly emphasizes the protection of Waters of the State, which is a
broader legal category defined under the Porter-Cologne Water Quality Control Act.
This definition includes any surface water or groundwater, including saline waters, within the
, boundaries of the state. The implication for the Grade 4 Manager is profound: a spill that soaks
into the ground in an area with a high water table or sensitive aquifer is now subject to rigorous
scrutiny as a potential violation of waste discharge requirements. The 2022 Order addresses the
pathways by which spilled sewage enters both surface waters and groundwater, requiring
agencies to consider these risks in their SSMP. This contrasts with Option A, which suggests a
narrowing of scope; the regulatory trend is invariably toward expansion. Option B is incorrect
because, while the new Order provides mechanisms to report private lateral spills, it does not
automatically transfer strict liability to the public agency unless the agency owns or operates the
lateral.
Question 2: Category 1 SSO Reporting Timelines
Scenario: At 09:00 hours on a Tuesday, your dispatch center receives a credible report of a
sanitary sewer overflow from a 24-inch trunk line. Field crews arrive at 09:30 and confirm that
approximately 5,000 gallons of untreated wastewater have discharged into a storm drain catch
basin. The storm drain outfall flows directly into a local creek, which is a tributary to a surface
water body. The crew establishes containment and begins recovery. As the Legally Responsible
Official (LRO), you must strictly adhere to the reporting "clock." Under Order 2022-0103-DWQ,
what is the mandatory deadline for submitting the Draft Spill Report to the California Integrated
Water Quality System (CIWQS)?
A. Within 24 hours of the agency becoming aware of the spill. B. Within 3 business days of the
agency becoming aware of the spill. C. Within 15 calendar days of the spill end date. D. Within 2
hours to Cal OES, followed by a certified report in 30 days.
Executive Analysis: The correct assessment is B. Managing the "reporting clock" is a primary
duty of the Grade 4 Manager. For a Category 1 SSO (any volume reaching surface water), the
timeline is bifurcated. The first requirement is notification to the California Office of Emergency
Services (Cal OES) within two hours of becoming aware of the discharge, particularly if it is
greater than 1,000 gallons. However, the specific question asks for the Draft Spill Report
submission to CIWQS.
The 2022 Order mandates that the Draft Report be submitted within three (3) business days of
the enrollee becoming aware of the spill. This three-day window allows the agency to gather
preliminary data, verify volumes, and upload photos without the pressure of an immediate
24-hour deadline, which was common in older permits. It allows for a more accurate initial filing.
The Manager must ensure that staff understands the distinction: Cal OES is for emergency
response (2 hours), while CIWQS is for regulatory documentation (3 days). Option C (15 days)
refers to the deadline for the Certified report, not the Draft.
Question 3: Certification Compliance Deadlines
Scenario: Following the Category 1 spill described in the previous scenario, your engineering
team has finalized the volume estimations based on flow metering data and visual extent
markers. You have reviewed the draft report in CIWQS and are prepared to sign off. To avoid a
mandatory minimum penalty or a Notice of Violation (NOV) for administrative non-compliance,
when must this Category 1 report be Certified in CIWQS?
A. 15 calendar days after the spill end date. B. 30 calendar days after the month in which the
spill occurred. C. 45 calendar days after the spill end date. D. 10 business days after the draft is
submitted.
Executive Analysis: The correct assessment is A. The certification step is the legal equivalent
