Department of Environmental Quality (DEQ) Environmental Inspector Certification — Questions and Answers
Question 1: What is a 'finding of no significant impact' (FONSI) in NEPA?
- An EPA determination that a project site contains no contaminated soil or groundwater
- A DEQ letter confirming that a project qualifies for a categorical exclusion under state environmental review
- A document prepared by a federal agency stating that a proposed action will not have a significant effect on the human environment and therefore does not require an EIS (Correct answer)
- A federal court ruling that an EIS was not required for a completed project
Correct answer: A document prepared by a federal agency stating that a proposed action will not have a significant effect on the human environment and therefore does not require an EIS
A FONSI concludes the EA process by documenting the agency's determination that the proposed action's impacts are not significant, eliminating the need for a full EIS.
Question 2: Which designation identifies the most strictly regulated hazardous wastes under RCRA because of their demonstrated harm to human health or the environment?
- Universal wastes
- Characteristic wastes
- Listed wastes (F, K, P, U lists) (Correct answer)
- Exempt wastes
Correct answer: Listed wastes (F, K, P, U lists)
Listed wastes—designated by the F, K, P, and U lists—are specific hazardous wastes that EPA has determined pose substantial risk, subjecting them to the most stringent RCRA controls.
Question 3: What is the difference between a 'permit by rule' and a standard DEQ permit?
- Permit by rule is a temporary authorization that expires after 30 days
- Permit by rule is a verbal authorization given during a DEQ inspection
- Permit by rule provides automatic authorization to facilities that meet specific qualifying criteria without requiring an individual permit application (Correct answer)
- Permit by rule applies only to federal facilities exempt from state regulation
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: Which state-level environmental review process is often called 'little NEPA' and mirrors the federal NEPA process?
- State Clean Air Act implementation plans
- State water quality certification under Clean Water Act Section 401
- State Environmental Quality Review Act (SEQRA) or equivalent state law (Correct answer)
- State RCRA hazardous waste program authorization
Correct answer: State Environmental Quality Review Act (SEQRA) or equivalent state law
Many states have enacted their own environmental review laws modeled on NEPA—often called 'little NEPAs'—that require state agencies to assess the environmental impacts of state-funded or state-approved actions.
Question 5: What is 'mitigation' in the context of environmental impact assessment?
- The transfer of environmental liability from the project applicant to the lead federal agency
- Financial penalties paid to the DEQ for environmental violations caused during project construction
- Measures taken to avoid, minimize, rectify, reduce, or compensate for adverse environmental impacts of a proposed action (Correct answer)
- The legal process of settling environmental lawsuits out of court
Correct answer: Measures taken to avoid, minimize, rectify, reduce, or compensate for adverse environmental impacts of a proposed action
Mitigation encompasses a hierarchy of measures—from avoiding impacts entirely to compensating for unavoidable impacts—used to reduce a project's overall environmental footprint.

- U.S. Environmental Protection Agency (EPA) (Correct answer)
- Army Corps of Engineers
- Federal Bureau of Investigation
- Department of Homeland Security
Correct 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.
Question 7: What is an Environmental Assessment (EA) under NEPA and how does it differ from an EIS?
- An EA is a shorter, preliminary document used to determine whether an EIS is required, while an EIS is a full analysis of significant impacts (Correct answer)
- An EA is required for all federal actions, while an EIS is only required for private projects
- An EA is prepared by the project applicant, while an EIS is always prepared by the lead federal agency
- An EA takes longer to complete than an EIS because it involves more public participation
Correct answer: An EA is a shorter, preliminary document used to determine whether an EIS is required, while an EIS is a full analysis of significant impacts
An EA is a concise NEPA document that determines whether a proposed action's impacts are significant; if not, a Finding of No Significant Impact (FONSI) is issued instead of proceeding to a full EIS.
Question 8: Under NEPA, what is a 'programmatic EIS' and when is it used?
- A broad environmental review of a program, plan, or policy that establishes the framework for future site-specific decisions (Correct answer)
- An abbreviated environmental review for routine agency programs that rarely cause significant impacts
- An EIS prepared for individual construction projects with multiple phases
- An EIS prepared by a state agency under its own environmental review law
Correct answer: A broad environmental review of a program, plan, or policy that establishes the framework for future site-specific decisions
A programmatic EIS analyzes the broad environmental consequences of a program or policy, with tiered site-specific reviews conducted later that can rely on and reference the programmatic analysis.
Question 9: What does Clean Water Act Section 401 water quality certification require?
- States to certify that federally licensed or permitted activities will comply with state water quality standards before the federal permit is issued (Correct answer)
- Federal agencies to obtain state approval before issuing any water-related environmental permits
- All dischargers in a state to maintain NPDES permits in good standing
- Wastewater treatment plants to meet specific effluent standards before receiving federal construction grants
Correct answer: States to certify that federally licensed or permitted activities will comply with state water quality standards before the federal permit is issued
