The Idaho Transportation Department (ITD) is committed to promoting effective and efficient transportation systems that are environmentally sensitive and cost effective throughout the planning, designing, construction, and maintenance stages.
ITD is dedicated to identifying and addressing socio-economic issues as well as endorsing activities to restore, enhance, and sustain natural ecological systems and their functions, while continuing to meet transportation safety and services needs. The term “environment” includes the natural environment, the built environment, the cultural and social fabric of the community, and the quality of life of the people.
To learn more about the Environmental Process or for specific questions, please go to the ITD Environmental Process Manual.
There are more than 40 federal and state environmental laws that affect transportation decisions. A unifying federal environmental law is the National Environmental Policy Act of 1969 (NEPA), which provides a framework for addressing the various environmental statutes, regulation and policies. NEPA is a procedural statute (40 CFR sec 1500) for decision-making during federal projects to assure analysis of social, economic and ecological impacts. ITD is required to provide a NEPA document for projects that are federally funded through the Federal Highway Administration (FHWA).
- Study a reasonable range of alternatives based on “Purpose and Need”
- Use a systematic, interdisciplinary approach while evaluating environmental factors during the planning process
- Widespread interagency coordination, review, and consultation
- Documentation of the environmental analysis process in plain language
- Provide the public opportunity to participate and comment throughout the process

Three Types of NEPA Documents
Environmental Evaluation (EE) – is an ITD document approved by the Idaho Division of FHWA for Categorical Exclusion (Cat. X) decision-making or auditing purposes.
- Examination of project concept and location regarding potential for socioeconomic or ecological impacts
- Determination of impact significance
Environmental Assessment (EA)
- Unsure if significant impacts
- Evaluation of key resources
- Finding Of No Significant Impact (FONSI)
Environmental Impact Statement (EIS)
- Significant Impacts
- More detailed evaluation
- Record Of Decision (ROD)
Air Quality impacts are evaluated for all Idaho Transportation Department (ITD) federally funded transportation projects to determine if the project will cause or contribute to a violation of National Ambient Air Quality Standards. ITD’s mission is to improve air quality by ensuring all ITD projects and operations comply with federal, state and local air quality laws and regulations, and by promoting strategies which reduce emissions of motor vehicle pollutants.

Cultural resource investigations involve documentation, interpretation, and preservation of prehistoric/historic archaeological sites, historic structures and traditional cultural properties that are evaluated as eligible for the National Historic Register. ITD’s policy is to either avoid adverse impacts to cultural resources or to minimize and mitigate the impacts for all projects requiring ground disturbance.
ITD is required by federal regulations in Section 106 of the National Historic Preservation Act (NHPA) of 1966 and Section 4(f) of the Department of Transportation Act of 1966, to assess the historic resources prior to potential impacts related to transportation construction and maintenance activities.
Section 106 Review Requires:
- Identification of historic properties that may be affected by the proposed transportation projects and resolves such conflicts
- Consulting with the State Historic Preservation Office (SHPO), the Tribal Preservation Offices (THPO), and other interested persons/parties during the early stages of planning and throughout the project
- Preparing cultural resource analysis describing each cultural resource, its specific location and potential impacts to it from the project
- Completing the “Determination of Significance and Effect” form (ITD-1502) with SHPO concurrence
Section 4(f) Evaluation Requires:
- Analysis of impacts to cultural resources on or eligible for the National Register of Historic Places (historic sites, bridges, archaeological resources) and impacts to public parks, recreation areas, and, wildlife and waterfowl refuges, resulting from transportation projects
- Identifying the resources being used by a project and examining alternatives to avoid that use

The Idaho Transportation Department must conduct hazardous materials investigations for any property ITD owns, manages, plans to sell, or plans to purchase. If hazardous materials are found to be present on ITD property, federal and state environmental laws requires ITD to cleanup and properly dispose of all hazardous materials regardless of whether the original source is from ITD activities, from a tenant, or inherited when property is acquired.
ITD seeks to identify hazardous materials early in the project development process through thorough investigations to reduce liability and to minimize delays. Advantages to this identification process include:
- Minimizing potential dangers to ITD and other personnel
- Protecting the environment from exposure to or spread of hazardous materials
- Minimize design and construction costs due to potential project delay or termination
- Reduce adverse publicity
HazMat Investigations are conducted in the following steps:
Administrative Review – (Required on all projects – ITD 652 Form)
- Published lists are reviewed to determine if there are any documented HazMat sites, underground storage tanks or contaminated ground water in/near the project area
- A windshield survey and interviews are performed
- Selected resource agencies are contacted
- If there is a potential impact, a Phase I or Phase 2 must be completed
Initial Site Assessment – (Phase I)
- Determines whether there is a potential HazMat risk
- Complete a Records Review of maps and historic documents to obtain information to help identify hazardous environmental conditions
- Perform a Site Reconnaissance to inspect property and any structures on the project for recognized hazardous environmental conditions
- Conduct Interviews with property owners or site managers to obtain information about possible hazardous environmental conditions that confirms information previously obtained or identifies new information
Preliminary Site Investigation – (Phase II)
- Confirm whether HazMat is present and extent of contamination
- Soil and water samples taken and analyzed
- Reports written to discuss physical environment and its relationship to potential contamination, sampling techniques, analysis results, health and safety considerations, identification of any contamination if found, conclusions, and remediation strategy and costs
Detailed Site Investigation – (Phase III)
- Conducted when existence of HazMat on the project site is confirmed
- Includes the Site Investigation, Remedial Action Plan and remediation
- Approximate clean up time can vary from 6 months to several years
- Authorization of a Phase III investigation will be coordinated through the Headquarters Environmental Section Manager

Tank Oil Spill – North of Smith Ferry, ID
Traffic Noise is increased by heavier traffic volumes, higher speeds and a greater percentage of trucks. ITD environmental studies involving major highway improvements must analyze existing noise levels and predict future noise levels to determine noise impacts. All traffic noise studies prepared for ITD projects must adhere to procedures and requirements as established by federal law, Federal Highway Administration (FHWA) regulations, and ITD noise analysis guidelines.

Wetlands – Section 404 of the Clean Water Act
Wetlands generally include swamps, marshes, bogs, and similar areas that are saturated by surface or groundwater and supports vegetation adapted for life in saturated conditions. They provide important functions including groundwater recharge, erosion control, shoreline stabilization, and fish and wildlife food and habitat.
Two Categories of Wetlands:
- Jurisdictional wetlands contain surface waters that have a connection to “Waters of the US”
- Non-Jurisdictional wetlands do not have a connection to “Waters of the US”
ITD’s policy is to avoid any activities that adversely affect wetlands during the design, construction, and maintenance of transportation projects. Appropriate action is taken to minimize and mitigate impacts that cannot be avoided.
Section 404 Permit – Required for discharging, dredging, or placing fill material within “Waters of the US” including wetlands to prevent quality degradation and overall loss of wetlands. Administered by the US Army Corps of Engineers (USACE).

Stormwater means stormwater runoff, snow melt runoff, surface runoff and drainage. Stormwater runoff may pick up and transport sediment, oil, and other pollutants. If not managed properly these pollutants can affect the quality of surface waters making them unsafe for drinking, fishing, swimming, or other activities.
Clean Water Act (CWA)
In 1972, Congress passed the Federal Water Pollution Control Act Amendments “to restore and maintain the chemical, physical, and biological integrity” of the Nation’s waters. The Clean Water Act (CWA) is a 1977 amendment to the Federal Water Pollution Control Act of 1972. The CWA set the basic structure for regulating discharges of pollutants to waters of the U.S.
National Pollution Discharge Elimination System (NPDES)
The NPDES permit program was introduced in 1972 and regulates discharges to “waters of the U.S.” Any discharge from a “point source” into a “waters of the U.S.” must have an NPDES permit. Stormwater discharges are regulated by NPDES permits. NPDES permits contains limits on allowed discharges, monitoring and reporting requirements, and other provisions to ensure that discharges do not harm water quality or public health. See EPA website for additional information
Idaho Transportation Division of Highways (ITD) has coverage under three different types of NPDES permits, including:
- Construction General Permit (CGP) – Construction activities that disturb greater than one acre of land and have the potential to discharge stormwater to a waters of the U.S.
- Municipal Separate Storm Sewer Systems (MS4)- Stormwater drainage from roads or property that drain into stormwater conveyance systems owned by the state, a city, a town, a village, a public university, a public hospital, a military base, a correctional facility or other public entity that discharges to waters of the U.S.
- Multi-Sector General Permit (MSGP)- Industrial activities that have the potential to discharge stormwater to a waters of the U.S., including sand and gravel mining. All EPA covered industrial activities are listed in Appendix D of the MSGP.
