This guide explores how highways impact the environment, focusing on air quality, cultural resources, noise, water/ecology, and hazardous waste. It covers the NYSDOT EPM, providing essential information on environmental procedures. Learn about emissions affecting air quality, such as CO, PM, HC, NOx, and air toxics, and how the CAL3QHC software models air quality for various traffic scenarios. Find emissions factor tables and helpful resources to understand and mitigate highway-induced environmental effects.

Objectives • Understand how highways can affect the environment • Be familiar with the environmental procedures manual
NYSDOT EPM • Environmental Procedures Manual • https://www.nysdot.gov/portal/page/portal/divisions/engineering/environmental-analysis/manuals-and-guidance/epm • Air Quality • Cultural Resources • Noise • Water/Ecology • Hazardous Waste • GIS
Air Quality • Emissions from vehicles affect air quality • Carbon Monoxide (CO) and Particulates (PM) are of major concern • Others—Hydrocarbons (HC), Nitrogen Oxides (NOx), and air toxics • CAL3QHC software can model air quality for different traffic configurations
Emissions Factors • Tables can be found here: • https://www.nysdot.gov/portal/page/portal/divisions/engineering/environmental-analysis/mobil6
