Pollution Prevention and Control Technologies for Plating Operations
Section 1 - Overview of Project Results
1.2 Overview of Users Survey Results
1.2.1 Characterization of Respondents
Exhibit 1-4 provides some basic facility characterization data for the survey respondents. The identity code of each shop is shown in column 1. These codes are used throughout the text where they are expressed as PS 001 through PS 318 (PS stands for plating shop and is used in the text to differentiate the Users Survey data from the literature references, which are simply numbered 1 through 522). The location of the shop is shown in column 2 and is expressed as a region of the U.S. The regional codes are as follows:
NE: Northeast
SE: Southeast
MW: Midwest
SC: South Central
W: West
FW: Far West
NW: NorthwestAlthough each of these regions has been specifically defined in terms of which states they contain, that information is not presented in the database or within this text in order to further preserve the confidentiality of the responses. Several respondents sent in anonymous survey forms and their location was unknown. The region for these shops is designated as "X". The total number of employees for each shop is shown in column 3. Additional data on employees are contained in the database, including the number of equivalent full-time employees working in the plating shop and a breakdown by labor category (platers, rackers, skilled trades, process engineers, chemists, environmental engineers, and other). Column 4 shows the year that the shop commenced metal finishing operations at the location for which the survey form was completed. Column 5 indicates the percentage of the plating work that is contract work (job shop). Where the percentage is less than 100%, the remaining percentage is captive shop work. The next two columns indicate the type of plating equipment that is present; either rack or barrel. The database contains additional plating equipment data concerning the level of automation present (e.g., automatic with manual loading vs fully automatic). The last column presents annual production data in terms of square feet of plating, pounds of parts processed or amp-hours of rectifier usage. Since most job shops are unable to track their work volume using these units or other non-fiscal units, this column contains many blanks. Exhibits 1-5 (a) (b) and (c) graphically display some of the facility characterization data.
