Requirements for Architectural Copper
Proiect water quality during installatian, 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,
Use Best Management Practices (BMPs)
The following Best Management Practices (BMPs)
discharges to storm drains.
must be implemented fo prevent prohibited
During /nsta//ation
• 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 vvater does not ilow fo the street or storm drain.
Bloc.l: oi�F sform drain inl�f i� necdec�.
o Collect rinse water in a fank and pump to the sanifary
se�n�er. Coniact your local� sanitary sewer agency before
discharging to rhe sanitary sewer.
o Collect the rinse water in a tank and haul off-site for
proper disposal.
• Consider coating the copper materiafs with an impervious
coating that prevents further. corrosion and runoff. This wifl
also mainiain the desired cofor for a longer time, requiring
less maintenance.
During Maintenance
Impiement fhe following BMPs during routine mainfenance 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 fo landscaping or to the sanitary sewer (with permission from the local
sanitary sewer agency). lf this is not an option, haul the wash water off-sife for proper disposal.
Proteci fhe �ay/Ocean and yourself!
If you are responsible for a discharge to the storm drain of non-
stormwater generafed by installing, cleaning, treating or washing
copper architectural features, you are in violation of the municipal
stormwater ordinance and may be subject fo a fine.
