Complete the following if hard chromium electroplating tanks are operated (check the box(es) 

that apply): 

J 

o 

o 

o 

The maximum cumulative potential rectifier capacity of the hard chromium electroplating 

tanks is greater than or equal to 60 million amp-hr/yr. This was determined by taking the 

swn of the. total installed rectifier capacity (amperes) multiplied by 8,400 hourslyr and by 

0.7 for each tank. 

The maximwn cumulative potential rectifier capacity of the hard chromium electroplating 

tanks is less than 60 million amp-hr/yT. This was detenruned by taking the sum of the 

total installed rectifier capacity (amperes) multiplied by 8,400 hourslyr and by 0.7 for 

each tanle . 

Records show that the facility's previous annual actual rectifier capacity of the hard 

chromium electroplating tanks was less than 60 million amp-yrlhr. If so, submit the 

records . that support this rectifier capacity for any 12-month period preceding the 

compliance date, or submit a description of how operations will change to meet this 

rectifier capacity limit. For new sources, the capacity can be that projected for the fIrst 

l2-month period of tank operation. 

The facility has accepted or will accept a Federally-enforceable limit of 60 million amphr/yr. on the maximum cumulative potential rectifier capacity of the hard chromium 

electroplating tanks. 

Check on of the following boxes that describes the facility's compliance status: 

, 

o 

The facility is in compliance with the provisions of 40 CFR Part 63, subpart N. 

The facility is not in compliance with the provisions of 40 CFR Part 63, subpart N. 

Print or type the name and title of the Responsible Official for the plant: 

Whitbv K. Ellsworth President 

Name Title 

A Responsible Official can be: 

• The president, vice-president, secretary, or treasurer of the company that owns the plant; 

• The owner of the plant; 

• The plant engineer or supervisor; 

• A government official if the plant is owned by the Federal, State, City or County 

government; or 

• A ranking military officer if the plant is located on a military base.

,1. Field Test Cba'nges and Problems 

Test No. 1 (M306-0-11 was interrupted for approximately eight, minutes due to a 

,Jalfunction with the rectifier. This did nof affect the test run as the sample train was shut down 

immediately and restarted when nonnal operating conditions resumed. Test Nos. 2 and 3 were 

completed without incidence.

The hazardous air pollutant analysis (Appendix B) pertains to the CTDEP air regulations. 

As indicated, the average actual stack concentration is 7% of the allowable Cr+6 concentration and 

clearly demonstrates compliance.
