The South Coast Air Quality Management District (SCAQMD) Evolution
SCAQMD. The South Coast Air Quality Management District (SCAQMD) continues to evolve. Here are a few new asbestos-related developments or rules that have been promulgated or clarified by the Agency in the past few years:
- The agency has abandoned AHERA sampling protocol and now requires a minimum 3 samples collected from each unique material, regardless of quantity and type.
- Concrete - floors, loading docks, stairwells, etc. - must be sampled prior to any disturbance. 3 samples required, but chipping a piece from the surface (instead of coring with a powered coring bit) is acceptable.
- The agency now requires a "discussion" of asbestos in asphalt, whenever it must be removed prior to removal. This came up when a roadway had to be removed to access asbestos - cement pipe. We take that to mean that sampling of asphalt is now required.
- In some cases, asbestos – cement pipe must be saw cut to facilitate new fittings. SCAQMD now requires a full enclosure (tent) and HEPA air filtration for this effort.
- We continually speak to and correspond with this agency on compliance issues and will happily share copies of those exchanges if requested.
