solutions that are used to obtain the desired shad.e 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.
Use Best Management Practices (BMPs)
The following Best Management Practices (BMPs) must be implemented to prevent prohibited
discharges to storm drains.
During Insiallation
• 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 fo 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 further corrosion and runoff. This will
also maintain the desired color for a longer _time, requiring
less maintenance.
During Maintenance
Implement the following BMPs during routine maintenance activities, such as power �vashing 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 storrn drain of non-
stormwater generated by installing, cleaning, tr�ating or washing
copper architectural features, you are in violation of the municipal
stormwater ordinance and may be subject to a fine:
