Air Quality/Noise Analysis/Hazardous Materials

The Environmental Engineering Section comprises the Air Quality, Hazardous Materials, Noise, and Water Quality Sections. The National Environmental Policy Act (NEPA), required on NDOT projects with federal funding, needs input from each of these disciplines. In addition, each section responds to public inquiries, maintains compliance with regulations, and protects the public interests.

Air Quality

Transportation conformity regulations require project sponsors to evaluate the potential air quality impacts that may result from construction and operation of a proposed transportation project. The primary function of the Air Quality section is to prepare or review NEPA documentation for NDOT construction projects. The Air Quality section also provides guidance to NDOT districts on air quality compliance and permitting issues. As needed, the Air Quality section prepares Requests for Proposals (RFP’s) and budgets for supplemental environmental programs, and manages field-based ambient monitoring studies performed by consultants.

Noise Analysis

As all Nevada drivers without air conditioning know, highways can be noisy. NDOT traffic noise engineers provide technical expertise by analyzing proposed highway projects for their noise impacts. The traffic noise engineers also respond to traffic noise complaints from residents that live near Nevada Highways.

NDOT follows the Federal Highway Administration’s noise standard as outlined in the Code of Federal Regulations 23 CFR 772, “Procedures for Abatement of Highway Noise.” The Traffic Noise Section also follows the NDOT state policy “Traffic and Construction Noise Abatement Policy.”

Hazardous Materials

Transportation projects may encounter waste from many sources: from routine NDOT activities, illegal releases, or waste inherited through acquired property. The Hazardous Materials team:

  • Helps NDOT staff at Districts and Headquarters comply with regulations regarding waste
  • Assists project managers in making informed transportation project decisions relating to property acquisition
  • Assists with the selection of alternatives
  • Makes recommendations on mitigation measures and costs and
  • Helps decide when early coordination with regulatory agencies is needed
  • The Hazardous Materials Section also assesses project impacts for Environmental Impact Statements and Environmental Assessments (as required by the NEPA process).

  • Water Quality

    Stormwater has the potential to carry pollutants from state road right of way into Nevada’s water bodies. The Department’s Water Quality Section works with all disciplines within NDOT, municipalities, stakeholders and other state and federal agencies to minimize this threat of pollutant transfer.

    Maintaining a Stormwater Management Plan for the Department and meeting or exceeding the requirements of the National Pollutant Discharge Elimination System, Municipal Separate Storm Sewer System Permit is the priority goal for the Water Quality Section. Using a wide range of best management practices throughout our State is the practice used to accomplish this goal.

    Protection of Nevada’s creeks, rivers and lakes is achieved by the constant focus on compliance and continual reach for innovation in NDOT’s effort to reduce or eliminate pollutant discharges from our infrastructure. Partnering with Nevadans is a way to monitor our water quality efforts. Please help us in identifying illicit discharges you may encounter in your daily activities. By using the public reporting page, you can help improve water quality. Be a part of NDOT’s effort to preserve the quality of Nevada’s resources!
