Environmental Compliance & Permits Flashcards

A KDOT project in an urban area requires an air quality conformity determination. This requirement applies when the project is located in a:

Answer: Nonattainment or maintenance area for criteria pollutants under the Clean Air Act

Transportation Conformity under the Clean Air Act applies to federally funded projects in areas designated as nonattainment or maintenance for NAAQS criteria pollutants.

Which element is NOT typically required in a KDOT Stormwater Pollution Prevention Plan (SWPPP)?

Answer: A list of on-site wildlife species observed during construction

SWPPPs must include site mapping, BMP descriptions, construction phasing, and inspection schedules, but do not require wildlife observation logs.

Under RCRA regulations, if a KDOT project generates hazardous waste during construction (e.g., from contaminated soil), what is the first step for proper management?

Answer: Characterize the waste through testing to determine if it meets hazardous waste definitions

Proper hazardous waste management begins with waste characterization (testing) to determine regulatory status before any storage, transport, or disposal decisions.

A KDOT inspector observes that a contractor's sediment basin has accumulated sediment to 50% of its design capacity. What action is required?

Answer: The sediment must be removed to restore design capacity before the next rain event

Industry standard and most permit conditions require sediment removal when a basin reaches 50% capacity to maintain design treatment volume for upcoming storms.

What is the minimum frequency for stormwater BMP inspections required under the NPDES Construction General Permit on KDOT project sites?

Answer: At least every 7 calendar days and within 24 hours after a 0.5-inch or greater rain event

The CGP requires inspections every 7 days and within 24 hours of qualifying storm events to ensure BMPs are functioning as designed.

When a KDOT project requires wetland mitigation, which mitigation option is given highest preference under the USACE mitigation rule (33 CFR Part 332)?

Answer: Permittee-responsible on-site avoidance and minimization, then wetland mitigation banks

The mitigation hierarchy requires first avoiding impacts, then minimizing, then compensating—and when compensation is needed, mitigation banks are preferred over in-lieu fee or permittee-responsible options.

Which federal law requires KDOT to consult with tribes regarding potential impacts to sacred sites or cultural resources on federal-aid projects?

Answer: National Historic Preservation Act (NHPA) Section 106 and Executive Order 13007

NHPA Section 106 mandates consultation with federally recognized tribes, and EO 13007 specifically requires agencies to protect tribal sacred sites on federal lands.
