CPWM Collection and Transportation Logistics 3 — Questions and Answers
Question 1: What federal regulation governs commercial driver licensing requirements for waste collection vehicle operators?
- OSHA 29 CFR 1910
- 49 CFR Part 383 (Correct answer)
- 40 CFR Part 258
- DOT FMCSA Part 395
Correct answer: 49 CFR Part 383
49 CFR Part 383 establishes CDL standards, knowledge tests, and skills tests required for operators of commercial motor vehicles including large waste trucks.
Question 2: Which waste collection system uses a vacuum pneumatic tube network to transport waste underground?
- Automated vacuum collection (AVAC) (Correct answer)
- Pneumatic compaction system
- Underground transfer pipeline
- Gravity feed sewer collection
Correct answer: Automated vacuum collection (AVAC)
AVAC systems use underground sealed pipes and vacuum pressure to transport waste from inlet stations to a central collection point, common in dense urban or campus settings.
Question 3: A compaction ratio of 4:1 for a rear-load truck means:
- The truck makes 4 stops per mile
- Loose waste volume is reduced to one-quarter its original volume (Correct answer)
- Four axles support the load
- The blade cycles 4 times per lift
Correct answer: Loose waste volume is reduced to one-quarter its original volume
A 4:1 compaction ratio means the compactor reduces loose waste to 25% of its original volume, allowing the truck to carry significantly more material per load.
Question 4: What is the key advantage of RFID-tagged carts in a waste collection program?
- They prevent theft of containers
- They enable automated tracking of collection completion and set-out rates (Correct answer)
- They allow residents to report overflows automatically
- They reduce the weight of the container
Correct answer: They enable automated tracking of collection completion and set-out rates
RFID tags on carts communicate with truck-mounted readers to automatically log when and where each cart was serviced, improving accountability and data collection.
Question 5: Under FMCSA hours-of-service rules, a property-carrying driver may drive a maximum of how many hours after 10 consecutive hours off duty?
- 10 hours
- 11 hours (Correct answer)
- 12 hours
- 14 hours
Correct answer: 11 hours
FMCSA 49 CFR Part 395 limits property-carrying drivers to 11 hours of driving following 10 consecutive hours off duty.
Question 6: What does 'diversion rate' measure in a municipal solid waste program?
- The percentage of routes completed before noon
- The proportion of waste diverted from landfill through recycling, composting, or reuse (Correct answer)
- The number of missed collections per 1,000 stops
- The ratio of residential to commercial collection
Correct answer: The proportion of waste diverted from landfill through recycling, composting, or reuse
Diversion rate measures the percentage of total waste generated that is redirected away from landfill disposal through recycling, composting, or other beneficial uses.
Question 7: Which collection method is most efficient for densely populated urban high-rise buildings?
- Individual curbside cart pickup
- Containerized dumpster service with front-load trucks (Correct answer)
- Backyard collection with manual carts
- Rural-style open-bed truck collection
Correct answer: Containerized dumpster service with front-load trucks
Front-load trucks servicing large shared dumpsters are most efficient for high-rise buildings because a single stop collects waste from many residents simultaneously.
