North American Industry Classification System (NAICS) Codes

NAICS is an acronym for North American Industry Classification System. These codes will replace the currently used SIC (Standard Industrial Classification) codes in the future. EPA requires the states to supply this information to them with the state's air emission inventory or hazardous waste data.

For most companies we have already entered a NAICS code for you for air reporting and hazardous waste reporting. You may change these codes if they are incorrect.
