1. Which federal statute establishes the primary framework for
regulating pollutant discharges to surface waters in the United
States?
A. Clean Air Act
B. Clean Water Act
C. Resource Conservation and Recovery Act
D. Safe Drinking Water Act
The Clean Water Act provides the principal legal structure for
regulating discharges of pollutants to U.S. waters, including
permitting and enforcement provisions.
2. Under the Resource Conservation and Recovery Act (RCRA), what is
the term for wastes posing significant risks to health or the
environment and subject to stringent management standards?
A. Municipal solid waste
B. Industrial nonhazardous waste
C. Hazardous waste
D. Construction and demolition debris
Hazardous wastes are specifically regulated under RCRA due to their
characteristics or listing, requiring strict handling, storage, and
disposal controls.
3. Under Michigan’s Part 55 Groundwater Protection statute, which of
the following is a primary driver for corrective action at a leaking
, underground storage tank site?
A. Odor complaints
B. Contamination of groundwater above cleanup criteria
C. Property value decrease
D. Aesthetic impacts to soil
Corrective action under Part 55 is triggered when contaminants
migrate to groundwater at levels exceeding state cleanup criteria,
requiring assessment and remediation.
4. What is the purpose of a National Pollutant Discharge Elimination
System (NPDES) permit?
A. Regulate hazardous waste transportation
B. Encourage voluntary pollution prevention
C. Authorize discharge of pollutants to surface waters
D. Certify drinking water treatment operators
An NPDES permit legally authorizes and limits pollutant discharges
from point sources to surface waters to protect water quality.
5. Which air pollutant is directly limited by National Ambient Air
Quality Standards (NAAQS) due to its impacts on human health and
visibility?
A. Oxygen
B. Hydrogen
C. Particulate matter (PM2.5/PM10)
D. Nitrogen gas
Particulate matter is a criteria pollutant with NAAQS due to
documented health effects and visibility impairment.
6. Under the Clean Air Act, a facility that emits 250 tons per year of a
regulated air pollutant is typically classified as what?
A. Area source
B. Major source
C. Minor source
D. Mobile source
Facilities exceeding major source thresholds (often 100 or 250 tpy
depending on pollutant) are regulated as major sources under the
Clean Air Act.
, 7. What is the primary focus of Michigan’s Part 31 Water Resources
Protection program?
A. Air emissions reporting
B. Underground storage tanks
C. Prevention of water pollution and protection of surface waters
D. Solid waste landfill siting
Part 31 protects water resources by regulating stormwater,
wastewater, and other potential pollution sources to preserve
surface water quality.
8. Which of the following is an example of a best management practice
(BMP) to control stormwater runoff at a construction site?
A. Increased vehicular traffic
B. Removal of vegetation
C. Silt fencing and sediment traps
D. Permanent paving before stabilization
Silt fences and sediment traps reduce erosion and capture sediment-
laden runoff, meeting stormwater BMP requirements.
9. Under RCRA, which characteristic describes wastes that can ignite
under certain conditions?
A. Corrosivity
B. Reactivity
C. Ignitability
D. Toxicity
Ignitability is a defined hazardous waste characteristic for materials
that readily catch fire, requiring special management.
10. What is the primary regulatory goal of the Safe Drinking Water
Act (SDWA)?
A. Regulate waste incineration
B. Ensure safe public drinking water supplies
C. Permit hazardous waste landfills
D. Monitor industrial wastewater discharges
The SDWA is designed to protect public health by regulating the
quality of drinking water in public systems.
11. Under Michigan’s Part 201 Environmental Remediation, what
triggers the liability for cleanup?
