BMP D05: Outdoor Painting &
Sandblasting
Pollutants of Concern:



Organics
Metals
Paint chips



Sediment
Oil & Grease
Trash & Debris
Purpose:
To prevent the discharge of pollutants associated with outdoor painting and sandblasting
(e.g., paint, rinse water, dust/sediment) from going into storm drains.
Application:
This BMP applies to any exterior building painting (minor touch up painting or architectural
coating) or sandblasting on areas including but not limited to building walls, steps, plazas,
patios, sidewalks, entryways, parking lots, roofs, and loading docks.
Practices:
1. Place tarps/plastic sheeting under objects prior to painting, scraping, or sandblasting to
contain and collect paint and particulate waste.
2. Prior to spray painting or sandblasting, shroud work area with plastic sheeting or
plywood to contain airborne overspray or dust/particulates. During these activities,
inspect the containment measures to ensure they are working.
3. Protect nearby storm drains from activities with rubber mats, filter fabric, or by covering
with a weighed down plastic liner
4. Only minor touch up painting or architectural coating (e.g., painting a stationary
structure) may be performed. All other painting must be performed either at the
campus paint shop or by a vendor in accordance with Air Pollution Control District
regulations.
5. Sweep, vacuum, shovel, and if necessary, use absorbent materials to collect particulate
wastes or paint not contained on tarps. Refer to BMP A02 for spill response
procedures.
6. Pollutants/debris generated by activities such as paint or metal chips,
sediment/particulates, trash/debris must be collected and properly disposed of to avoid
potential discharge into a storm drain.
7. Collect and contain rinse water from ALL painting activities (including water based
paint) for disposal through EH&S. Fax or email collection request to (858) 534-9708 or
hazwaste@ucsd.edu.
8. Avoid sanding or painting in windy weather.
Frequency &
Maintenance:
Implement these procedures for all exterior painting and sandblasting activities.
Training:
Shops, trades, and theater staff that perform outdoor work activities that could contribute
pollutants to the campus storm water system must take the “Annual Shop & Studio
Environmental Compliance & Hazards Training” which includes storm water pollution
prevention and spill prevention, control, and cleanup.
