Regulatory Compliance and Environmental Safety Flashcards

Which U.S. law establishes cradle‑to‑grave management of hazardous waste?

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.

Under OSHA’s Hazard Communication Standard, employers must provide workers with:

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.

A Large Quantity Generator (LQG) must ship accumulated hazardous waste off‑site within:

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.

NPDES permits issued under the Clean Water Act regulate:

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.

CERCLA, also known as Superfund, primarily addresses:

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.

A Title V operating permit under the Clean Air Act is required for:

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.

In the hierarchy of controls for workplace hazards, Personal Protective Equipment (PPE) is considered:

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.

Spills that exceed a substance’s Reportable Quantity (RQ) must be reported to the National Response Center:

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.

EPA publication SW‑846 provides guidance on:

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.
