DEQ Environmental Permits and Licensing 1 — Questions and Answers
Question 1: What is the purpose of a National Pollutant Discharge Elimination System (NPDES) permit?
- To authorize air emissions from industrial stacks
- To authorize the discharge of pollutants from a point source into waters of the United States under defined limits (Correct answer)
- To permit the land disposal of solid waste at municipal landfills
- To license hazardous waste treatment facilities under RCRA
Correct 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.
Question 2: Under the Clean Air Act, what is a Title V Operating Permit?
- A permit required for minor emission sources with less than 100 tons per year of regulated pollutants
- A comprehensive federal operating permit that consolidates all air emission requirements for major sources into a single document (Correct answer)
- A construction permit for new major stationary air emission sources
- A permit specifically for mobile source emissions like truck fleets
Correct answer: A comprehensive federal operating permit that consolidates all air emission requirements for major sources into a single document
A Title V permit is a comprehensive operating permit for major stationary sources that consolidates all applicable air quality requirements into one enforceable document.
Question 3: What is the difference between a 'permit by rule' and a standard DEQ permit?
- Permit by rule provides automatic authorization to facilities that meet specific qualifying criteria without requiring an individual permit application (Correct answer)
- Permit by rule is a verbal authorization given during a DEQ inspection
- Permit by rule applies only to federal facilities exempt from state regulation
- Permit by rule is a temporary authorization that expires after 30 days
Correct 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.
Question 4: What is a 'general permit' in DEQ permitting and how does it differ from an individual permit?
- A general permit covers a category of similar facilities or activities under standard conditions, while an individual permit is tailored to a specific facility (Correct answer)
- A general permit has no expiration date, while an individual permit must be renewed every 5 years
- A general permit applies to federal facilities only, while individual permits cover private entities
- A general permit is issued by the EPA directly, bypassing state DEQ authority
Correct answer: A general permit covers a category of similar facilities or activities under standard conditions, while an individual permit is tailored to a specific facility
General permits cover multiple similar facilities or activities under standardized conditions, offering administrative efficiency compared to individually negotiated permits.
Question 5: Which type of Clean Air Act permit is required before constructing a new major source of air pollution?
- Title V operating permit
- Prevention of Significant Deterioration (PSD) or New Source Review (NSR) construction permit (Correct answer)
- NPDES stormwater permit
- RCRA Part B storage permit
Correct answer: Prevention of Significant Deterioration (PSD) or New Source Review (NSR) construction permit
New or modified major stationary sources must obtain a PSD or NSR permit before construction, ensuring that new emissions will comply with air quality standards and Best Available Control Technology requirements.
Question 6: What is the standard term (duration) for most NPDES permits issued by a state DEQ?
- 1 year
- 2 years
- 5 years (Correct answer)
- 10 years
Correct answer: 5 years
NPDES permits are issued for a maximum term of 5 years, after which they must be renewed to ensure effluent limits reflect current technology and water quality standards.
