Copper from Buildings May Harm Aquatic Life Copper can harm aquatic life in San Francisco Bay. Water that comes info 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 fhe 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 instailation, cleaning, treating and washing of architectural copper. Use Best Management Practices (BMPs) The following Best Management Practices (BMPs) discharges to storm drains. must be implemenfed to prevent prohibited During /nstal/ation • If possible, purchase copper materials that have been pre-patinated at the faciory. • 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 ilow fo the street or siorm drain. f3lock off storm drain inlef ii i�ecaec�. o Collect rinse water in a fank and pump to the sanitaiy sewer. Coniact 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 materiafs with an impervious coating that prevents further corrosion and runoff. This will also maintain the desired cofor for a longer time, requiring less maintenance. Sform drain rnlet is blocked to prevenf prohibited discharge. The water must be pumped and disposed of properly.
