Laws, Regulations & Guidance


Virginia's environmental laws are available on the General Assembly's Legislative Information System website:


The Virginia Air Pollution Control Board promulgates Virginia's air regulations. These cover stationary sources, such as industrial facilities and other fixed-emission sources; mobile sources, such as vehicle emissions; and regulations to ensure that certain projects conform with federal requirements.

The official published text of agency regulations is provided by the Division of Legislative Services through links to the Legislative Information System (LIS). Links to PDF documents have been provided for your convenience to more easily find material in some of the larger chapters. Should there be a conflict between the two, please contact Karen Sabasteanski.
