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

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

SCAQMD staff has developed PR 1466 to establish requirements to minimize off-site fugitive particulate matter emissions that contain certain toxic air contaminants from earth-moving activities at sites within SCAQMD jurisdiction that have been designated as cleanup sites by the US Environmental Protection Agency, the DTSC, SWRCB or RWQCB. Thus, some sites that may that may be affected by PR 1466 may also be identified on lists compiled by the DTSC per code 65962.5. PR 1466 requirements would also apply to any site conducting earth-moving activities that is identified by the SCAQMD's executive officer as having soil that contains certain TACs at levels exceeding soil cleanup thresholds. PR 1466 establishes a PM 10 ambient dust limit and dust control measures at PR 1466 applicable sites, and would require notification to the executive officer when cleanup operations begin or PM10 emission limits are not met. PR 1466 applicable sites will be required to install and maintain signage to inform the community and discourage unauthorized access. PR 1466 also includes additional requirements to limit cleanup activities for sites at schools and early education centers. In situations where additional requirements to limit cleanup activities for sites at schools and early education centers. In situations where additional regulatory flexibility is necessary, PR 1466 allows alternative dust control measures if approved by the executive officer. While the reduction of TACs and PM10 will be expected to create an environmental benefit, the activities that site operators may undertake to comply with PR 1466 in the draft EA did not result in the identification of any environmental topic areas that would be significantly adversely affected.
