This document is a detailed engineering drawing for an Oil Containment Cross Sections and Details plan prepared by the Water and Power Department for the City of Pasadena, California. The technical drawing provides comprehensive cross-section views and specific construction details for oil containment systems at the Wilson and Oak Knoll Substations, designed to prevent potential transformer and electrical equipment oil spills and meet federal environmental regulations under Title 40 CFR Part 112.

The engineering drawings illustrate multiple technical specifications including section views (G-G, D-D, K-K), detailed construction notes, and specific design elements such as expansion joint materials, existing foundation interactions, concrete trench configurations, and base/sub-base section requirements. The drawings include precise measurements, installation instructions for concrete structures, reinforced pipe installations, and structural details for oil containment infrastructure. The technical drawing is marked as Sheet 1 of 3, suggesting additional related documentation exists, and includes professional engineering annotations, scale references, and a official city department seal.
