TDOT preferred format, for the TDOT Hazardous Materials Section to review and provide further 
recommendations as to whether additional studies may be necessary. 
Assumptions: 
▪ It is assumed that no Phase I Environmental Site Assessment (ESA), Phase II ESA, or Asbestos 
Containing Materials (ACM) surveys will be conducted as part of this proposed scope of services 
and cost estimate. If the Client, TDOT, or another state and/or federal agency requests additional 
hazardous materials studies, these services can be provided but will be considered Additional 
Services beyond this scope of services. 
Air Quality and Noise 
The Consultant will make preliminary Air Quality and Noise determinations.  
Air Quality 
The Consultant will review FHWA’s Updated Interim Guidance on Mobile Source Air Toxic Analysis in NEPA 
Documents, dated October 18, 2016, to determine if the project is in an area that is in attainment for all 
regulated criteria pollutants.  
Noise 
Based on the project scope, it is assumed that the project is a Type III project in accordance with the FHWA 
noise regulation, Procedures for Abatement of Highway Traffic and Construction Noise (23 C.F.R. 722) and 
the Tennessee Department of Transportation’s Policy on Highway Traffic Noise Abatement (TDOT’s noise 
policy). Therefore, a Type I noise analysis is not proposed, and the Consultant will provide the preliminary 
determination that the project qualifies as Type III to TDOT. 
Environmental Technical Information to be provided by TDOT 
The TDOT Environmental Division will be responsible for providing the following environmental technical 
information:  
• Native American Consultation 
• Air Quality  
• Noise 
Following receipt of the above listed environmental technical information from the TDOT Environmental 
Division, the Consultant will review and incorporate the information/data into the TEER document. 
Task 3.3 – Initial Studies Coordination Package and Section 106 Assessment  
Based on a review of available project plans, the Consultant will prepare an Initial Studies Coordination 
Package and Section 106 Assessment for the proposed project utilizing TDOT’s preferred templates.  
Documentation and mapping included within the Initi al Studies Coordination Package and Section 106 
Assessment will include the following: 
• Development of the purpose and need for the proposed project as well as a discussion of relevant 
project background. Project background information will be identified through a review of online 
planning documents, grants, and other project history provided by the Consultant Project Manager.  
• Development of a description of the proposed project, a description of the existing conditions within 
the project area, and a photo log of existing conditions along the project corridor. Photos for this 
effort will be collected by the Consultant Project Manager.  
• Preparation of a project location map and topographic map in GIS. 
• The following technical studies completed in Task 2 will be incorporated into the Initial Studies 
Coordination Package and Section 106 Assessment. Technical studies from Task 2 not 
incorporated into these documents will be incorporated directly into the TEER document.
