Module 7: Regulatory Requirements - Title IV - Practice Problems

Instructions:: Answer these questions on a sheet of paper and check your responses against those provided below.

: Answer: CEMS is the acronym for Continuous Emissions Monitoring System.

#2: The objective of Title IV is to reduce ___________ by limiting emissions of its two main precursor compounds: ____________ and ____________.

: Answer:
Acid rain
Nitrogen oxides
Sulfur dioxides; The objective of Title IV is to reduce acid rain by limiting emissions of its two main precursors: nitrogen oxides and sulfur dioxides.

#3: On what type of facilities does Title IV impose regulatory controls?

: Answer: Title IV imposes regulatory controls on large stationary source combustion systems, specifically electric utilities, because they are primary emitters of sulfur dioxides and nitrogen oxides.

#4: What measures must owners and operators of stationary sources take in order to comply with the monitoring and reporting requirements of Title IV?

: Answer: Owners and operators of stationary plants subject to Title IV regulations must install continuous emission monitoring systems (CEMS) for sulfur dioxide, nitrogen oxides, volumetric flue gas flow rate, and opacity for each unit. The data collected by these instruments are used to calculate the total pollutant emission rates expressed in tons per year. The facility must report this information to EPA on a regular basis. The facility can calculate emissions using general plant operating parameters when CEMS data are unavailable.

#5: What measures are taken against facilities that exceed their annual emission limits under Title IV?

: Answer: Sources that exceed their annual emission limitations will be assessed penalties and are required to offset the excess emissions by an equal tonnage amount in the subsequent year.
