Item 10.2:
Compliance Demonstration shall include the following monitoring:

Monitoring Type: MONITORING OF PROCESS OR CONTROL DEVICE PARAMETERS AS SURROGATE

Monitoring Description:
The Water Seal Tank is equipped with a Caustic Addition System and Caustic Spray Column as a back-up to control and neutralize any potential low pH situation. A low pH situation is not expected and would only occur if any halogenated material is feed to the reactor by mistake. Should this occur then the off gas would become acidic and the pH of the water seal tank would drop.

If the pH of the Water Seal Tank drops below 6.0, then the following corrective action is required:
#1 – The feed system to the Reactor will automatically shut off.
#2 – The caustic pump will start and caustic will be pumped to the top of the Spray Tower and through the Spray Nozzles to neutralize the material in the Water Seal Tank to control it at a pH of 7 to 8.
