CPII Safety & Environmental Compliance 5 — Questions and Answers
Question 1: A public infrastructure inspector is reviewing a contractor's lockout/tagout (LOTO) program. Under OSHA, what is the primary purpose of energy control procedures during equipment maintenance?
- To track equipment maintenance schedules and costs
- To prevent unexpected energization or startup that could injure workers (Correct answer)
- To ensure equipment warranties are maintained during service
- To comply with manufacturer service interval requirements
Correct answer: To prevent unexpected energization or startup that could injure workers
LOTO procedures under OSHA 29 CFR 1910.147 protect workers from the unexpected release of hazardous energy during equipment servicing and maintenance.
Question 2: Which Clean Air Act program requires new or modified major sources of air pollution, such as large diesel generators at infrastructure facilities, to obtain permits before construction?
- New Source Review (NSR) / Prevention of Significant Deterioration (PSD) (Correct answer)
- National Ambient Air Quality Standards (NAAQS) attainment program
- Title V Operating Permit Program
- Reasonably Available Control Technology (RACT) program
Correct answer: New Source Review (NSR) / Prevention of Significant Deterioration (PSD)
The NSR/PSD program under the Clean Air Act requires pre-construction permits for new major sources or major modifications that increase emissions above significance thresholds.
Question 3: An inspector discovers an unmarked drum at a road construction site leaking a clear liquid with a petroleum odor. Under CERCLA, who bears liability for cleanup costs?
- Only the generator who originally produced the waste
- Only the current property owner where the drum was found
- Potentially responsible parties (PRPs) including generators, transporters, and past/current owners (Correct answer)
- Only the contractor currently working at the site
Correct answer: Potentially responsible parties (PRPs) including generators, transporters, and past/current owners
CERCLA imposes strict, joint and several liability on all potentially responsible parties—generators, transporters, and past and current owners/operators—for cleanup costs.
Question 4: During a sewer pipeline inspection, atmospheric testing reveals oxygen levels of 18%. What action is immediately required before entry?
- Enter quickly and complete the inspection within 10 minutes
- Don a supplied-air respirator before entering
- Ventilate until O2 levels reach at least 19.5% before entry (Correct answer)
- Document the reading and proceed with buddy system protocols
Correct answer: Ventilate until O2 levels reach at least 19.5% before entry
Atmospheres below 19.5% oxygen are oxygen-deficient and IDLH; forced air ventilation must raise O2 to at least 19.5% before any worker entry.
Question 5: A construction project near a navigable waterway must comply with Section 401 of the Clean Water Act. What does a Section 401 Water Quality Certification confirm?
- That the project meets federal drinking water standards
- That the discharge will comply with applicable state water quality standards (Correct answer)
- That wetland mitigation credits have been purchased
- That the project is exempt from NPDES permit requirements
Correct answer: That the discharge will comply with applicable state water quality standards
A Section 401 Water Quality Certification, issued by the state, certifies that a federally permitted activity will comply with applicable state water quality standards.
Question 6: Which OSHA standard specifically addresses safety requirements for workers performing inspection activities on or near operating highway traffic?
- 29 CFR 1926.200 — Signs, Signals, and Barricades
- 29 CFR 1926 Subpart G — Signs, Signals, and Barricades with MUTCD reference (Correct answer)
- 29 CFR 1926.651 — Excavations
- 29 CFR 1926.502 — Fall Protection Systems
Correct answer: 29 CFR 1926 Subpart G — Signs, Signals, and Barricades with MUTCD reference
OSHA 29 CFR 1926 Subpart G references the MUTCD for temporary traffic control requirements protecting workers in highway work zones.
Question 7: What is the significance of a 'Categorical Exclusion' (CE) under NEPA for routine infrastructure maintenance projects?
- It exempts a project from all environmental laws and permitting
- It identifies actions that normally do not significantly affect the environment and do not require an EA or EIS (Correct answer)
- It provides automatic approval for projects under $1 million in cost
- It requires agencies to conduct a full environmental review but on an expedited timeline
Correct answer: It identifies actions that normally do not significantly affect the environment and do not require an EA or EIS
A Categorical Exclusion identifies classes of actions that agencies have determined do not individually or cumulatively cause significant environmental effects, eliminating the need for EA or EIS preparation.
