Rule 1466 – Control of Particulate Emissions from Soils with Toxic Air Contaminants

The purpose of Rule 1466 is to minimize off-site fugitive dust emissions from earth-moving activities at sites containing specific toxic air contaminants by establishing dust control measures.

Rule 1466 applies to any owner or operator conducting earth-moving activities of soil with applicable toxic air contaminant(s) as defined in paragraph (c)(15) of the rule that have been identified as contaminant(s) of concern at a site.  The rule focuses on the toxic air contaminants listed in Table I of the rule.  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.  The rule does not apply to earth-moving activities of soil with applicable toxic air contaminant(s) of less than 50 cubic yards.
