The purpose of Rule 1466 - Control of Particulate Emissions from Soils with Toxic Air Contaminants, adopted on July 7, 2017, is to minimize off-site fugitive dust emissions containing toxic air contaminants by establishing dust control measures that can be implemented during earth-moving activities at sites that contain certain toxic air contaminants. Rule 1466 will focus on the following toxic air contaminants: arsenic, asbestos, cadmium, hexavalent chromium, lead, mercury, nickel, and polychlorinated biphenyls. The provisions in Rule 1466 include ambient PM10
monitoring, dust control measures, notification, signage, and recordkeeping requirements. Rule 1466 allows for alternative dust control measures, ambient dust concentration limits, and other provisions provided they are approved by the Executive Officer.
Rule 1466 requires notifications prior to beginning earth-moving activities and when ambient PM10
dust concentration limits are exceeded. Submit all Rule 1466 notifications to Rule1466@aqmd.gov
