Describe the primary function of the carbon canisters connected to G-202A. Why is this important?
Describe the primary function of the carbon canisters connected to G-202A. Why is this important?
The carbon canisters capture hydrocarbon vapors exiting G-202A, preventing their release into the atmosphere. This is important for environmental protection and air quality.
Explain the process by which oil is removed from the water in G-202A, and where the separated oil is ultimately routed.
Explain the process by which oil is removed from the water in G-202A, and where the separated oil is ultimately routed.
Oil is manually skimmed from the water in G-202A into a collection box. From there, it's routed by P-98 (Oil Skimmer Pump) back to G-202B.
What is the key difference between how P-94 and P-95A/B are powered, and why might this difference be important during a power outage?
What is the key difference between how P-94 and P-95A/B are powered, and why might this difference be important during a power outage?
P-94 (Dry Weather Pump) is powered by an electric motor, while P-95A/B (Wet Weather Pumps) are powered by diesel motors. During a power outage, P-95A/B can continue to operate, providing essential water routing capabilities, while P-94 would be non-functional.
Under what weather conditions is P-94 primarily used, and what is its destination for the water it pumps?

Study Notes
- Water from G-202B, Z-56, 1791/1797 flare seal drum overflow, and utilities hydroblast slab flows to G-202A; Unit 1791/179y OWS is routed to G-202A.
- Oil entering G-202A is manually skimmed, collected, and routed to G-202B by P-98 (Oil Skimmer Pump).
- During dry weather, water is routed by P-94 (Dry Weather Pump) to surge tanks in the Utilities Treatment Area.
- During rain, P-95A/B (Wet Weather Pumps) automatically start to assist in routing excess water.
- Hydrocarbon vapors exiting G-202A are routed to carbon canisters to prevent atmospheric emissions.
G-202A (Storm Water Sump / API Separator)
- G-202A is a concrete basin (10’W x 70’L) with a galvanized steel cover and a vent breather.
- It collects oily water from G-202B, Z-56, 1791/1797 flare seal drum overflow, and utilities hydroblast slab.
- Oil is separated and pumped back to G-202B, while water is pumped to the Utilities Treatment Area for further processing.
P-98 (Oil Skimmer Pump)
- P-98 (Oil Skimmer Pump) is a nitrogen-driven diaphragm pump.
- It routes skimmed oil from G-202A back to G-202B.
P-94 (Dry Weather Pump)
- P-94 (Dry Weather Pump) is a single-stage centrifugal pump, driven by a 20 HP horizontally-mounted induction electric motor.
- It routes water from G-202A to surge tanks in the Utilities Treatment Area.
P-95A/B (Wet Weather Pumps)
- P-95A/B (Wet Weather Pumps) are single-stage centrifugal pumps driven by diesel motors.
- They supplement P-94 during rainstorms, routing additional water entering G-202A to surge tanks in the Utilities Treatment Area.
