✍️ Sample CESCO Questions & Answers
1. Which of the following is a key requirement for a hazardous waste satellite accumulation area (SAA) under RCRA?
RCRA regulations for satellite accumulation areas (SAAs) at 40 CFR 262.15 state that containers must be at or near the point of generation where the waste initially accumulates and must be under the control of the operator of the process generating the waste. While weekly inspections and contingency plans are required for central accumulation areas, they are not specific requirements for SAAs. The accumulation limit for non-acute hazardous waste in an SAA is 55 gallons.
2. The OSHA PSM standard requires a Process Hazard Analysis (PHA) to be revalidated at least every:
OSHA 29 CFR 1910.119(e)(6) requires that PHAs be updated and revalidated at least every five years after initial completion.
3. What is the primary purpose of a Hearing Conservation Program baseline audiogram?
The baseline audiogram establishes each worker's initial hearing threshold, enabling comparison with annual audiograms to detect standard threshold shifts (STS) early.
4. A Small Quantity Generator (SQG) has an on-site accumulation time limit for hazardous waste of 180 days. Under what specific circumstance can this be extended to 270 days?
RCRA regulations at 40 CFR 262.16 allow a Small Quantity Generator (SQG) to accumulate hazardous waste on-site for up to 180 days without a permit. This time limit can be extended to 270 days if the treatment, storage, or disposal facility (TSDF) where the waste must be sent is located more than 200 miles away.
5. Which of the following is an essential element of a final, high-quality environmental compliance audit report?
The audit report must provide context for the findings. A clear statement of the scope (what was audited and the criteria used), objectives (the purpose), and the timeframe reviewed is crucial for the reader to understand the boundaries and relevance of the audit's conclusions and findings.
6. Under PSM, how long must employers retain the five most recent compliance audit reports?
29 CFR 1910.119(o)(3) requires employers to retain the two most recent compliance audit reports, not a set number of years — they must be kept until replaced by newer audits.
