The California Regional Water Quality Control Board, San Francisco Bay Region, hereinafter called the Regional Water Board, finds that:
1. The Pacific Rod and Gun Club (the Club) is a public recreation facility located on the west side of Lake Merced in San Francisco (see Figure 1). The Club occupies approximately 10 acres of land that is leased from the City and County of San Francisco. The San Francisco Public Utilities Commission (the SFPUC), a public agency which is part of the City and County of San Francisco, currently has jurisdiction over Lake Merced. The Club built and maintains facilities at the Site, including skeet and trap ranges where shotguns are used to shoot pellets at clay targets. The Club has operated the facilities and the ranges at the current location since 1934. The facilities are used daily, and the ranges are currently in
operation three days a week. For the purposes of this Order, the Club and the SFPUC are jointly considered the Dischargers.
