This is a project specification document from the City of Pasadena Water and Power Department for the proposed Oil Containment System at the Oak Knoll Substation, located at 525 S. Oak Knoll Avenue in Pasadena, California. The project involves constructing an oil containment system for existing bank 3A, bank 3B, and switchgear, designed to prevent potential oil spills from transformers and electrical equipment from impacting the surrounding environment. The document includes detailed site plans, a key location map, and comprehensive general notes outlining construction requirements, safety protocols, and technical specifications.

The project is aimed at bringing the substation into compliance with federal environmental regulations, specifically Title 40 Code of Federal Regulations Part 112 (Oil Pollution Prevention). The scope of work includes sawcutting and removing existing concrete pads, excavation, backfilling, soil compaction, installation of reinforced concrete structures and trenches with grates, and associated demolition and cleanup activities. The technical specifications provide detailed guidance on concrete strength, reinforcement, grading, and installation requirements, with emphasis on maintaining minimum clearances, addressing existing underground utilities, and ensuring comprehensive environmental protection measures.
