This is a technical drawing document for cathodic protection corrosion control systems on the Los Angeles County Metropolitan Transportation Authority's (LACMTA) E Line passenger rail project, financed in part through a Federal Transit Administration grant under the Federal Transit Act of 1964. The project encompasses cathodic protection installations across multiple Metro divisions and locations, including Division 1 through Division 18 and three additional maintenance locations throughout Los Angeles County. The scope of work involves the installation of high-potential magnesium anodes, test stations, reference electrodes, and related electrical components at three primary stations: Mariachi Station, Soto Station, and East Portal. Work requirements include trenching and excavation, utility location verification through potholing and Underground Service Alert (USA) notification 48 hours prior to work commencement, anode installation and cable securing, backfill composition preparation, and pavement reconstruction with traffic control measures. The drawings indicate specific action items at each station, including installation of new anodes in pairs at multiple test station locations and two elevator rooms per station, with some existing test stations requiring wire excavation and location work.

The contract specifications require all construction to conform to National Association of Corrosion Engineers (NACE) standards and approved project specifications. Magnesium anode specifications include 48-pound ingot weight (96 pounds packaged), 5" x 5" x 31" ingot dimensions, and specific chemical composition requirements for magnesium, aluminum, manganese, copper, nickel, iron, and other elements. Installation requirements include proper backfill composition of 75 percent gypsum, 20 percent bentonite, and 5 percent sodium sulfate; installation of #12 AWG THHN and XHHW cable with pin-brazed connections to steel pipes; and reference electrode installation. The contractor bears responsibility for Cal/OSHA permits for excavations exceeding five feet in depth, proper disposal of excavated materials, surface restoration to pre-construction conditions, and compliance with all encroachment permits from local authorities having jurisdiction. The drawing set includes eight sheets addressing cover information, overall alignment, station-specific details, equipment specifications, installation procedures, and electrical isolation requirements.
