,Virginia Landfill Operator License Exam | Waste Management (2026) Q&A
1. Which agency is primarily responsible for issuing waste management facility operator
licenses in Virginia?
A) Environmental Protection Agency (EPA)
B) Virginia Department of Health (VDH)
C) Virginia Board for Waste Management Facility Operators (VBWMO)
D) Virginia Department of Transportation (VDOT)
Correct Answer: Virginia Board for Waste Management Facility Operators (VBWMO)
Rationale: The Virginia Board for Waste Management Facility Operators is the statutory
body that grants, renews, and enforces licensure for waste facility operators in the
Commonwealth. The EPA sets federal standards, but licensing is a state function under the
Board's authority.
2. What is the minimum distance a Virginia landfill must maintain from a private drinking
water well?
A) 50 feet
B) 100 feet
C) 250 feet
D) 500 feet
Correct Answer: 250 feet
Rationale: Virginia regulations specify a minimum separation of 250 feet between a landfill
and a private water supply well to prevent contamination from leachate or gas migration.
This setback ensures adequate buffer for groundwater protection.
,3. Which federal law is the primary statute regulating solid waste management in the United
States?
A) Clean Air Act
B) Resource Conservation and Recovery Act (RCRA)
C) Safe Drinking Water Act
D) Toxic Substances Control Act
Correct Answer: Resource Conservation and Recovery Act (RCRA)
Rationale: RCRA is the main federal law governing the management of solid and hazardous
waste, setting standards for generation, transportation, treatment, storage, and disposal.
The Clean Air Act addresses air emissions, not solid waste management.
4. Under Virginia regulations, which type of landfill gas monitoring is required for a
municipal solid waste landfill that has been closed for more than 5 years?
A) Weekly ambient air sampling only
B) Quarterly groundwater sampling only
C) Continuous or periodic methane monitoring at the property boundary
D) Annual soil gas testing only
Correct Answer: Continuous or periodic methane monitoring at the property boundary
Rationale: Closed landfills can continue to produce methane for many years. Virginia
regulations require continuous or periodic methane monitoring at the landfill boundary to
prevent explosive gas accumulation and ensure public safety.
5. A Class II license permits an operator to manage which type of facility?
A) Transfer station only
B) Medical waste incinerator
C) Sanitary landfill
, D) Waste-to-energy combustor
Correct Answer: Sanitary landfill
Rationale: Class II licensure authorizes operators of sanitary landfills, industrial landfills, and
construction/demolition/debris (CDD) landfills. Transfer stations and medical waste
incinerators typically require different classifications.
6. What is the minimum distance a Virginia landfill must maintain from a regularly flowing
body of water or river?
A) 50 feet
B) 100 feet
C) 200 feet
D) 500 feet
Correct Answer: 100 feet
Rationale: Virginia regulations require landfills to maintain a 100-foot setback from regularly
flowing bodies of water to protect surface water quality and prevent contamination. This
setback helps prevent runoff and leachate from entering waterways.
7. What is the typical composition of methane in landfill gas (LFG)?
A) 10-20%
B) 25-35%
C) 45-60%
D) 75-90%
Correct Answer: 45-60%
