Precision Machine and Supply

This former chrome plating and machine shop in Odessa, Ector County is currently in the Operation and Maintenance phase of the Superfund Program.

Site Background

The Precision Machine & Supply site (the site) is located at 500 West Olive Street in Odessa. This site was operated from 1952 until December 1980 as a machine and chrome-plating shop. The 0.75-acre site consists of a metal building, an alley, and a fenced yard. Operations at the site generated chromic acid rinsate, which was stored in a 1,500-gallon fiberglass underground tank, prior to disposal off site. Two concrete slabs,equipped with drains leading to the tank, were used as wash racks for rinsing chrome parts.
