CPWM Regulatory Compliance & Environmental Safety — Questions and Answers
Question 1: Which U.S. law establishes cradle‑to‑grave management of hazardous waste?
- Clean Water Act
- Resource Conservation and Recovery Act (RCRA) (Correct answer)
- Toxic Substances Control Act
- National Environmental Policy Act
Correct answer: Resource Conservation and Recovery Act (RCRA)
The Resource Conservation and Recovery Act (RCRA), enacted in 1976, is the principal federal law in the United States governing the disposal of solid waste and hazardous waste. Specifically, Subtitle C of RCRA establishes a comprehensive 'cradle-to-grave' system for managing hazardous waste, tracking it from its generation through transport, treatment, storage, and final disposal.
Question 2: Under OSHA’s Hazard Communication Standard, employers must provide workers with:
- Personal tax forms
- Safety Data Sheets for each hazardous chemical (Correct answer)
- Vehicle maintenance logs
- Air emission inventories
Correct answer: Safety Data Sheets for each hazardous chemical
Under OSHA's Hazard Communication Standard (HazCom), employers are legally required to provide workers with Safety Data Sheets (SDSs) for all hazardous chemicals in the workplace. SDSs contain critical information about chemical hazards, safe handling procedures, emergency measures, and protective equipment. This ensures employees are informed and equipped to work safely with hazardous materials.
Question 3: A Large Quantity Generator (LQG) must ship accumulated hazardous waste off‑site within:
- 30 days
- 60 days
- 90 days (Correct answer)
- 180 days
Correct answer: 90 days
Under RCRA regulations, a Large Quantity Generator (LQG) of hazardous waste is permitted to accumulate hazardous waste on-site for a maximum of 90 days. This timeframe allows generators to accumulate sufficient quantities for cost-effective transportation and disposal. Exceeding this 90-day limit generally requires the facility to obtain a hazardous waste storage permit, which involves more stringent requirements.
Question 4: NPDES permits issued under the Clean Water Act regulate:
- Solid waste recycling rates
- Discharges of pollutants into navigable waters (Correct answer)
- Noise levels near airports
- Indoor air quality in schools
Correct answer: Discharges of pollutants into navigable waters
The National Pollutant Discharge Elimination System (NPDES) permit program, established under the Clean Water Act, specifically regulates direct discharges of pollutants from point sources into navigable waters. Its purpose is to control water pollution by setting limits on what can be discharged and requiring facilities to obtain a permit before discharging any pollutants. This helps protect and restore the quality of the nation's waterways.
Question 5: CERCLA, also known as Superfund, primarily addresses:
- Chemical accident prevention planning
- Remediation of contaminated sites and cost recovery (Correct answer)
- Regulation of pesticide residues on food
- Energy efficiency in federal buildings
Correct answer: Remediation of contaminated sites and cost recovery
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, primarily addresses the cleanup of uncontrolled or abandoned hazardous waste sites. Its core functions include identifying responsible parties, ensuring the remediation of contaminated sites, and enabling the government to recover cleanup costs. This legislation aims to protect public health and the environment from the dangers posed by historical contamination.
Question 6: A Title V operating permit under the Clean Air Act is required for:
- Any facility with electric forklifts
- Major sources exceeding pollutant emission thresholds (Correct answer)
- Office buildings under 10,000 sq ft
- Retail stores with parking lots
Correct answer: Major sources exceeding pollutant emission thresholds
Under Title V of the Clean Air Act, an operating permit is required for 'major sources' of air pollution. These are facilities that emit or have the potential to emit pollutants above specific thresholds defined by the EPA. The Title V permit consolidates all applicable Clean Air Act requirements into a single document, ensuring comprehensive compliance and accountability for large industrial emitters.
Question 7: In the hierarchy of controls for workplace hazards, Personal Protective Equipment (PPE) is considered:
- The most preferred control
- The last line of defense after other controls (Correct answer)
- An engineering control
- Mandatory for office workers at all times
Correct answer: The last line of defense after other controls
In the hierarchy of controls for workplace hazards, Personal Protective Equipment (PPE) is considered the least effective and therefore the last line of defense. The hierarchy prioritizes eliminating the hazard, substituting it, implementing engineering controls, and then administrative controls, before resorting to PPE. PPE only protects the worker if used correctly and consistently, and it does not eliminate the hazard itself.
Question 8: Spills that exceed a substance’s Reportable Quantity (RQ) must be reported to the National Response Center:
- Within 7 days
- Immediately upon knowledge of the release (Correct answer)
- By the end of the calendar quarter
- Only if asked by local media
Correct answer: Immediately upon knowledge of the release
Spills or releases of hazardous substances that exceed their Reportable Quantity (RQ) must be reported immediately to the National Response Center (NRC). This immediate notification requirement, mandated by CERCLA and EPCRA, ensures that emergency responders can be deployed quickly to assess the situation, mitigate hazards, and protect public health and the environment. Delays in reporting can lead to increased risks and potential penalties.
Question 9: EPA publication SW‑846 provides guidance on:
- Noise monitoring at airports
- Test methods for evaluating solid and hazardous waste (Correct answer)
- Erosion control on farms
- Radiation dosage in hospitals
Correct answer: Test methods for evaluating solid and hazardous waste
EPA publication SW-846, officially titled 'Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,' provides a comprehensive collection of analytical methods for characterizing solid and hazardous waste. These methods are crucial for determining the chemical composition and physical properties of waste materials. This guidance is essential for compliance with RCRA regulations and for making informed decisions regarding waste management and remediation.
