Under the Spill Prevention, Control, and Countermeasure (SPCC) rule, what type of facilities are required to develop a written SPCC plan?
Answer: Facilities with aggregate above-ground oil storage capacity above 1,320 gallons that could reach navigable waters
Facilities with aggregate aboveground oil storage above 1,320 gallons (or underground storage above 42,000 gallons) that have a reasonable possibility of discharge to navigable waters must have an SPCC plan.
What is the primary purpose of an 'air emissions inventory' at a process facility?
Answer: To quantify and report all emission sources for regulatory compliance and permitting
An emissions inventory systematically quantifies all pollutants released from all sources at a facility to support permit applications, compliance reporting, and regulatory submissions.
A process technician is conducting monthly visual inspections of a thermal oxidizer. What key performance indicator should be recorded to demonstrate compliance?
Answer: Combustion chamber temperature and pressure drop across the unit
Combustion chamber temperature is the primary operating parameter for thermal oxidizers because it directly indicates whether sufficient heat is being applied to destroy pollutants, and pressure drop indicates flow conditions.
What does 'bubble concept' mean in the context of air emission regulations?
Answer: Treating multiple emission points as a single source allowing internal emission trading
The bubble concept treats all emission sources within a facility as if covered by an imaginary bubble, allowing internal trading of emission reductions as long as total facility emissions do not exceed the overall limit.
Under the Clean Water Act's NPDES program, what does a 'technology-based effluent limit' mean for a process facility's wastewater discharge?
Answer: A discharge limit determined by the best available technology for controlling pollutants
Technology-based effluent limits require facilities to achieve pollutant reductions based on the best available technology (BAT) or best conventional technology (BCT) regardless of receiving water conditions.
A process technician discovers that a cooling tower discharge has elevated levels of total dissolved solids exceeding NPDES permit limits. What is the appropriate immediate response?
Answer: Notify the facility environmental manager and follow the permit's deviation reporting procedures
Exceeding permit limits requires immediate notification of the environmental manager and following established deviation reporting procedures to meet permit compliance obligations.
What is 'emissions trading' under a cap-and-trade program, and how does it benefit industrial facilities?
Answer: Allowing facilities to buy and sell emission allowances, providing flexibility to reduce emissions cost-effectively
Cap-and-trade programs set a total emissions cap and allow facilities to buy additional allowances if they exceed their allocation or sell surplus allowances if they reduce below it, achieving overall reductions at lower total cost.
