Mixed Deck — All DEQ Topics Flashcards

What is the primary component of smog that can cause respiratory problem?

Answer: Ground-level Ozone

Ground-level ozone is a primary component of smog, formed when pollutants from vehicles and industrial emissions react in sunlight. When inhaled, it can irritate the respiratory system, causing coughing, throat irritation, and aggravating conditions like asthma and emphysema.

What is 'pump and treat' technology for contaminated groundwater remediation?

Answer: Extracting contaminated groundwater, treating it above ground to remove contaminants, and then discharging or reinjecting the treated water

Pump and treat extracts contaminated groundwater, treats it using methods such as air stripping or activated carbon, and manages the treated effluent, providing hydraulic control and mass removal.

What is the purpose of a National Pollutant Discharge Elimination System (NPDES) permit?

Answer: To authorize the discharge of pollutants from a point source into waters of the United States under defined limits

An NPDES permit authorizes a facility to discharge pollutants into navigable waters subject to specific effluent limits, monitoring requirements, and reporting conditions established by the DEQ.

What is a 'brownfield' site in the context of DEQ land contamination programs?

Answer: A real property whose expansion, redevelopment, or reuse may be complicated by the presence or potential presence of hazardous substances or pollutants

A brownfield is a property where real or perceived contamination complicates redevelopment, and DEQ brownfield programs provide liability protections and cleanup assistance to encourage productive reuse.

What is the 'scoping' process in NEPA environmental review?

Answer: An early public process used to identify the range of issues, alternatives, and impacts to be analyzed in the EIS

Scoping is an early public participation process that identifies significant issues for the EIS, focuses the analysis on important questions, and eliminates insignificant ones, making the review more targeted and efficient.

Which DEQ program addresses stationary source emissions of greenhouse gases through permit requirements under the Clean Air Act?

Answer: Title V Operating Permits

Title V Operating Permits under the Clean Air Act are the primary permitting mechanism that can include GHG emission conditions for large stationary sources.

What is the difference between a 'permit by rule' and a standard DEQ permit?

Answer: Permit by rule provides automatic authorization to facilities that meet specific qualifying criteria without requiring an individual permit application

A permit by rule automatically authorizes activities that meet specific predefined criteria, reducing the regulatory burden for lower-risk operations without eliminating accountability.

Which federal rule requires facilities emitting 25,000 metric tons or more of CO2 equivalent per year to report their greenhouse gas emissions to the EPA?

Answer: Greenhouse Gas Reporting Program (GHGRP)

The EPA's Greenhouse Gas Reporting Program (GHGRP) mandates annual GHG reporting from large emitters of 25,000 metric tons CO2e or more.

What is the primary component of smog that can cause respiratory problem?

Answer: Ground-level Ozone

Ground-level ozone (O3) is a key component of smog and is a powerful respiratory irritant. It can cause inflammation of the airways, coughing, and shortness of breath, particularly affecting individuals with asthma or other respiratory conditions. Exposure to high levels of ozone can lead to significant health problems.

Which agency has authority to take over enforcement if a state DEQ fails to adequately enforce federal environmental standards?

Answer: U.S. Environmental Protection Agency (EPA)

The EPA retains authority to conduct federal enforcement actions if a state agency fails to adequately implement and enforce delegated federal environmental programs.

Which DEQ enforcement document is publicly accessible and notifies the community about a facility's compliance status?

Answer: Publicly available compliance report or permit file

DEQ permit files and compliance reports are public records, allowing communities to monitor the environmental performance of nearby facilities.

What type of waste is classified as hazardous?

Answer: Industrial chemicals

Hazardous waste is defined by its potential to cause harm to human health or the environment due to its ignitability, corrosivity, reactivity, or toxicity. Industrial chemicals often possess these characteristics, making them a significant category of hazardous waste that requires special handling, treatment, and disposal to prevent contamination and adverse effects. Organic waste, paper, and plastic bottles are generally classified as municipal solid waste unless contaminated.

Under DEQ enforcement, what is the benefit of a regulated entity submitting a Root Cause Analysis after a violation?

Answer: It demonstrates good faith and can support penalty mitigation

Submitting a root cause analysis demonstrates that a facility is taking the violation seriously and working to prevent recurrence, which regulators may consider when determining penalties.

What is the primary concern with chlorinated solvents like trichloroethylene (TCE) at contaminated sites?

Answer: TCE is a Dense Non-Aqueous Phase Liquid (DNAPL) that sinks below the water table and is a probable human carcinogen, making cleanup extremely difficult

Chlorinated solvents like TCE are DNAPLs that sink through aquifers and are classified as probable human carcinogens, making them among the most challenging and concerning groundwater contaminants to remediate.

Which of the following methods is considered the most environmentally friendly for managing organic waste?

Answer: Composting

Composting is the most environmentally friendly method for managing organic waste because it mimics natural decomposition processes. It transforms organic materials like food scraps and yard waste into nutrient-rich soil amendment, reducing landfill waste and greenhouse gas emissions. Unlike landfilling or incineration, composting returns valuable nutrients to the soil, promoting sustainable agriculture and soil health.

What is the 'National Priorities List' (NPL) and how does a site get listed?

Answer: A federal list of the nation's most contaminated hazardous waste sites eligible for Superfund cleanup funding, based on the Hazard Ranking System score

The NPL identifies priority contaminated sites eligible for federal Superfund remedial action, with listing based on Hazard Ranking System scores that evaluate contamination severity and population exposure.

What is the purpose of the National Pollutant Discharge Elimination System (NPDES) permit program?

Answer: To regulate the discharge of pollutants into U.S. waters

The National Pollutant Discharge Elimination System (NPDES) is a permit program authorized by the Clean Water Act. It controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Facilities must obtain an NPDES permit, which sets limits on what can be discharged and requires monitoring and reporting, to ensure compliance with water quality standards.

The Resource Conservation and Recovery Act (RCRA) primarily governs the management of which type of waste?

Answer: Hazardous waste

The Resource Conservation and Recovery Act (RCRA) is the principal federal law in the United States governing the disposal of solid waste and hazardous waste. Its primary objective is to protect human health and the environment from the potential hazards of waste disposal. RCRA establishes a comprehensive "cradle-to-grave" system for managing hazardous waste, from its generation to its final disposal.

What is a Phase I Environmental Site Assessment (ESA) designed to identify?

Answer: Recognized Environmental Conditions (RECs) — evidence of historical or current releases of hazardous substances through records review, interviews, and site reconnaissance

A Phase I ESA is a non-invasive investigation that identifies recognized environmental conditions through document review and site observation without collecting samples.

Which international agreement established legally binding emission reduction targets for developed countries and is a key reference in state DEQ climate programs?

Answer: Kyoto Protocol

The Kyoto Protocol (1997) was the first international agreement establishing binding GHG reduction targets for developed (Annex I) countries.
