Prevention Program Requirements for Architectural Copper
CIe.hWater. N1a1th9C0MN1Unh9.
Protect water quality during installation, cleaning, treating, and washing!
Copper from Buildings May Harm Aquatic Life
Copper can harm aquatic life in San Francisco Bay. Water that comes
into contact with architectural copper may contribute to impacts,
especially during installation, cleaning, treating, or washing. Patination
solutions that are used to obtain the desired shade of green or brown
typically contain acids. After treatment, when the copper is rinsed to
remove these acids, the rinse water is a source of pollutants.
Municipalities prohibit discharges to the storm drain of water used in the
installation, cleaning, treating and washing of architectural copper.
Building with copper
gutter and drainpipe.
Use Best Management Practices (BMPs)
The following Best Management Practices (BMPs) must be implemented to prevent prohibited
discharges to storm drains.
During Installation
• If possible, purchase copper materials that have been pre-patinated at the factory.
• If patination is done on -site, implement one or more of the following BMPs:
o Discharge the rinse water to landscaping. Ensure that the
rinse water does not flow to the street or storm drain.
Block off storm drain inlet if needed.
o Collect rinse water in a tank and pump to the sanitary
sewer. Contact your local sanitary sewer agency before
discharging to the sanitary sewer.
o Collect the rinse water in a tank and haul off -site for
proper disposal.
• Consider coating the copper materials with an impervious
coating that prevents furthercorrosion and runoff. This will
also maintain the desired color for a longer time, requiring
less maintenance.
prohibited discharge. The water must be
pumped and disposed of properly.
During Maintenance
Implement the following BMPs during routine maintenance activities, such as power washing the roof,
re-patination or re -application of impervious coating:
• Block storm drain inlets as needed to prevent runoff from entering storm drains.
• Discharge the wash water to landscaping or to the sanitary sewer (with permission from the local
sanitary sewer agency). If this is not an option, haul the wash water off -site for proper disposal.
Protect the Bay/Ocean and yourself!
If you are responsible for a discharge to the storm drain of non-
stormwater generated by installing, cleaning, treating or washing
copper architectural features, you are in violation of the municipal
stormwater ordinance and may be subject to a fine.
