PO Environmental Monitoring & Emissions

Question 1

What does a Continuous Emissions Monitoring System (CEMS) measure?

Accepted Answer

Real-time stack emissions such as SO2, NOx, CO, and opacity

Answer

CEMS continuously measures and records pollutant concentrations in stack gases to demonstrate compliance with air permit emission limits.

Question 2

What is the primary environmental concern with flaring of hydrocarbon gases?

Accepted Answer

Flaring releases CO2, unburned hydrocarbons, SO2, and NOx into the atmosphere

Answer

Even an efficient flare generates CO2, and inefficient flaring releases uncombusted hydrocarbons, NOx, and SO2, all of which are regulated air pollutants.

Question 3

Under the EPA's Spill Prevention, Control, and Countermeasure (SPCC) rule, facilities must develop a plan if they:

Accepted Answer

Store oil in quantities that could reasonably discharge to navigable waters if a spill occurred

Answer

SPCC plans are required for facilities that store oil above regulatory thresholds and where a spill could reach navigable US waters.

Question 4

Which regulation primarily governs the management and disposal of hazardous waste at US industrial facilities?

Accepted Answer

Resource Conservation and Recovery Act (RCRA)

Answer

RCRA establishes the framework for proper management of hazardous waste from generation through disposal to protect human health and the environment.

Question 5

What is a Leak Detection and Repair (LDAR) program designed to do?

Accepted Answer

Identify and fix fugitive VOC emissions from process equipment components

Answer

LDAR programs use periodic monitoring of valves, connectors, pumps, and other components to detect and repair fugitive VOC leaks per EPA Method 21.
