✍️ Sample DEQ Questions & Answers
1. What is the primary component of smog that can cause respiratory problem?
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.
2. What is 'pump and treat' technology for contaminated groundwater remediation?
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.
3. What is the purpose of a National Pollutant Discharge Elimination System (NPDES) permit?
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.
4. What is a 'brownfield' site in the context of DEQ land contamination programs?
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.
5. What is the 'scoping' process in NEPA environmental review?
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.
6. Which DEQ program addresses stationary source emissions of greenhouse gases through permit requirements under the Clean Air Act?
Title V Operating Permits under the Clean Air Act are the primary permitting mechanism that can include GHG emission conditions for large stationary sources.
