Envir_eng_HPAir Quality/Traffic Noise Analysis/Hazardous Materials/Naturally Occurring Asbestos & Erionite (NOA/E)

The Environmental Engineering Section comprises the Air Quality, Hazardous Materials, Traffic Noise, and NOA/E 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 & Traffic Noise Analysis

Transportation conformity regulations require project sponsors to evaluate the potential air quality effects 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. NDOT traffic noise engineers analyze proposed highway projects for traffic 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" and 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. NDOT operations may require the use of regulated materials.  
The Hazardous Materials team assist:

  • NDOT staff at Districts and Headquarters comply with regulations regarding materials and waste
  • Project managers in making informed transportation project decisions relating to property acquisition
  • Assists with the selection of alternatives
  • On mitigation measures and costs 
  • 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).

Natural Occurring Asbestos & Erionite (NOA/E)

Transportation projects and activities may encounter NOA/E. The NOA/E section assesses the existence and effect of NOA/E on material usage and management and identifies potential worker safety concerns.
