AWIA & Emergency Response Plans (ERPs)

Under Section 2013 of America's Water Infrastructure Act of 2018 (AWIA), community water systems serving more than 3,300 people must certify completion of a Risk and Resilience Assessment (RRA) and an Emergency Response Plan (ERP):

• Evaluates vulnerabilities to malevolent acts (vandalism, cyber intrusions on SCADA networks) and natural disasters (hurricanes, riverine flooding, ice storms).
• Identifies critical interconnections, alternate water sources, and mutual aid agreements (such as NJWARN — New Jersey Water/Wastewater Agency Response Network).
• ERPs must be coordinated with county Offices of Emergency Management (OEM) and Local Emergency Planning Committees (LEPCs), and updated every 5 years.

Standby Power & Hurricane Resilience

• Auxiliary Standby Generators: Water treatment plants, finished water booster stations, and major wastewater lift stations must feature on-site diesel or natural gas generators equipped with Automatic Transfer Switches (ATS) that restore power within 10 to 30 seconds of grid failure.
• Fuel Storage Capacity: Facilities must maintain sufficient dedicated on-site fuel storage to operate the plant under full emergency pumping and treatment load for a minimum of 48 to 72 hours without refueling.
• Flood Elevation Protection (Post-Sandy Standards): In accordance with NJDEP flood hazard rules, all critical electrical switchgear, motor control centers (MCCs), standby generators, and chemical metering systems must be elevated at least 1 to 3 feet above the 100-year and 500-year Base Flood Elevations (BFE).

NJDEP 24-Hour Hotline Notification Triggers (1-877-WARN-DEP)

In New Jersey, water and wastewater utilities are legally mandated to immediately report specific environmental and public health emergencies to the NJDEP 24-Hour Environmental Action Line at 1-877-WARN-DEP (1-877-927-6337) within two hours of occurrence:

1. Sanitary Sewer Overflows (SSOs): Any unpermitted release, bypass, or overflow of untreated or partially treated sewage onto ground surfaces, into storm drains, or into receiving waters.
2. Distribution Pressure Drops Below 20 psi: If a water distribution system, pressure district, or major transmission main experiences a pressure loss below 20 psi (138 kPa), a Boil Water Advisory (BWA) must be evaluated and declared immediately. Low pressure permits groundwater and contamination to enter drinking water mains through pipe cracks via back-siphonage.
3. Chemical Spills Exceeding Reportable Quantities (RQ): Any uncontrolled release of hazardous chemicals exceeding CERCLA/EPCRA reportable limits (e.g., 10 pounds or more of chlorine gas released within a 24-hour period).
4. Disinfection Treatment Failure: Any catastrophic loss of chlorination, UV disinfection, or filtration that results in un-disinfected or turbid water entering the potable distribution main or stream discharge.

6. Practical Operational Scenarios & Exam Traps

Practical Operational Scenario

A distribution crew is dispatched to repair a ruptured 8-inch ductile iron water main in the center of an asphalt suburban roadway. The backhoe excavates a trench 7 feet deep and 4 feet wide. The soil is damp clay loam with angular gravel, which was backfilled during original street construction.

• Safety Protocol Execution:
  1. The Competent Person recognizes that because the street soil was previously excavated and backfilled, it can NEVER be classified as Type A. It is classified as Type B soil.
  2. Because the trench is 7 feet deep (exceeding the 5-foot threshold), protective systems are mandatory. The crew installs an engineered aluminum trench shield (trench box).
  3. The Competent Person verifies that the top of the trench box extends 20 inches above street grade (exceeding the 18-inch minimum overhang requirement) and that the box rests 18 inches above the trench bottom (within the 2-foot allowable clearance for pipe bedding).
  4. An aluminum extension ladder is placed inside the trench box, tied off at the top, extending 3.5 feet above the street surface, located 15 feet from where the pipe repairmen are working (well within the 25-foot travel rule).
  5. Spoil piles and the backhoe are positioned 3 feet back from the trench edge (exceeding the 2-foot minimum buffer).
  6. Before cutting the broken pipe, operators lock out the booster pump feeding the line using a padlock and tag at the circuit breaker disconnect, dissipate line pressure, and verify zero energy.

Critical Exam Traps

• Trap 1: The Street Soil Type A Trap. Exam questions frequently describe a deep clay excavation under a roadway and ask if it can be sloped as Type A (3/4:1). The answer is NO; previously excavated ground can never be Type A—it must be treated as Type B or C.
• Trap 2: Ladder vs. Protective System Depth. Remember the differing depth thresholds: Ladders are required at 4 feet or deeper; protective systems (trench boxes, shoring) are required at 5 feet or deeper.
• Trap 3: Maximum Ladder Travel Distance. The maximum lateral travel distance to a ladder is 25 feet (meaning ladders are spaced at most 50 feet apart).
• Trap 4: Spoil Pile Setback. Spoil must be kept at least 2 feet back from the edge.
• Trap 5: Control Circuit LOTO. Operating a stop pushbutton, emergency stop cord, or SCADA mouse-click is NOT legal LOTO. Energy must be isolated at the physical circuit breaker or disconnect switch.
• Trap 6: NJDEP Boil Water Pressure Trigger. The universal threshold requiring a boil water advisory and immediate NJDEP notification is when distribution pressure falls below 20 psi.

3. Budgets, Procurement, Asset Management & Supervisory Administration

Administrative content is quietly one of the largest scored areas on the operator examination: 26 of 100 questions on the Water Distribution Class IV exam and 18 of 100 on the Wastewater Collection Class IV exam fall under security, safety, administrative procedures, and public interactions. Candidates who dismiss this material as "not real operations" give away a quarter of the exam.

Operating vs Capital Budgets

Power and chemicals are the two largest controllable operating costs at most plants. Optimizing aeration dissolved oxygen setpoints, right-sizing coagulant dose from jar tests, shifting pumping to off-peak tariff periods, and correcting a leaking chemical feed line all show up directly in the operating budget. WPI lists "optimize the use of energy and chemicals" as a scored job task for exactly this reason.

Cost Estimating and Procurement

• Estimating a job means totaling labor (crew size × hours × loaded rate), equipment (owned equipment at an hourly rate, or rental), materials, fuel and power, traffic control and restoration, and a contingency.
• Unit-rate benchmarking — dollars per foot of main replaced, dollars per foot of sewer cleaned, dollars per million gallons treated — lets an operator sanity-check a bid and lets a supervisor calculate cleaning and production rates for crew scheduling.
• Procurement sequence: define the need and write a specification or bid specification → obtain quotes or issue a formal bid for purchases above the local public contracts threshold → evaluate for responsiveness and responsibility, not price alone → issue a purchase order → verify receipt against the specification → approve the invoice. Public utilities in New Jersey purchase under the Local Public Contracts Law, so an operator who "just orders it" from a favored vendor creates a legal problem, not merely a paperwork problem.
• Sole-source and emergency purchases are narrow exceptions that require written justification. An emergency main break authorizes emergency procurement; a predictable annual chemical order does not.
• Inventory control: track chemicals, parts, and general supplies with minimum and maximum levels, reorder points based on lead time and usage, and first-in-first-out rotation for chemicals with shelf lives such as sodium hypochlorite and polymer.

Asset Management

Asset management ties the operating and capital budgets together and, for New Jersey water purveyors with more than 500 service connections, is a statutory requirement under the Water Quality Accountability Act. A functioning program answers five questions:

1. What do I own? A complete asset inventory with location, material, size, and installation date, maintained in GIS.
2. What is it worth? Replacement cost and remaining useful life.
3. What is its condition? Condition assessment from inspection, CCTV, break history, and testing.
4. What is critical? Risk = Likelihood of Failure × Consequence of Failure. A 60-year-old 6-inch main in a cul-de-sac and a 60-year-old 24-inch transmission main under a hospital have the same likelihood and radically different consequence.
5. What is my long-term funding plan? The renewal schedule — for New Jersey water mains, a 150-year replacement cycle or another justified cycle — and the rate or borrowing strategy that pays for it.

Supervisory and Administrative Duties

WPI's criteria list supervisory tasks as scored content: determining and assigning work schedules and shift coverage, enforcing policies and safety procedures, conducting performance evaluations, making hiring decisions, initiating and investigating disciplinary action, resolving grievances, training new operators and managing employee certification programs, developing and maintaining standard operating procedures, keeping records and writing internal, state, and federal reports, responding to customer complaints and work orders, and reviewing easement and right-of-way issues.

Exam Trap Alert: On the exam, the "best" administrative answer is almost always the one that documents the action and follows the established procedure, not the one that resolves the problem fastest. Verbally approving an emergency purchase, disciplining a worker without documentation, or fixing a customer complaint without logging it are all scored as wrong even when the physical outcome is correct.
