C #� CITY OF STOCKTON ENVIRONMENTAL CONTROL 2500 Navy Dr. Stockton CA 95206 INSPECTION X ANNUAL INSPECTION TELEPHONE CALL MEETING NOTES Company: Western Square Industries, Inc. Inspector: Larry Williams Location: 1621 Broadway Stockton CA 95205 Date: 3-2-99 Time: 1330 Contact: Warren Snider, VP Operations Telephone: 444-0921 IL _Philip Bartko, Plant Engineer The purpose of this inspection was to verify the sewage disposal method of Western Square (WS). WS fabricates, cleans, and powder coats metal farm fencing, wine barrel racks, and water bottle racks. This industry is a metal finisher and regulated under 40 CFR Part 433.17 for sewer discharges. The sanitary sewer line was checked on Report Ave adjacent to WS. No flow was noted indicating a process wastewater discharge. The storm line was checked at the same location. This manhole had a lateral coming from the direction of WS, and had soapy wastewater entering the manhole. A sample was collected from the storm manhole for metals and pH, and sealed with evidence tape. Contact was made with Snider, and I requested to inspect the plant operations. He contacted Bartko, and asked him explain the manufacturing process. This company utilizes a three stage washer to clean and prepare metal pieces for powder coating. The first stage of the unit cleans the parts in a 3% solution iron phosphoric acid. The second stage is a clear rinse that overflows back to the first stage as make-up water. The third stage is a clear rinse that overflows and is pumped to dry wells on site. WS does not have a sewer connection. The cleaned parts are powder coated various colors and dried in a 450 degree oven. No painting occurs on site. Larger parts (water bottle racks) were being pressure washed using a 3% iron phos. solution by hand on 20' X 20' wash pad. This pad is exposed to stormwater and drains to the dry wells. No wastewater treatment is done on site.
