RE: O'CONNOR COMPANY SUPERFUND SITE 

INSPECTION REPORT - September 2012 

Dear Mr. Connelly: 

Enclosed is a copy of the inspection of the O'Connor Company Superfund Site carried out on September 

25, 2012. This inspection was conducted in accordance with the Operations and Maintenance Plan dated 

October 2009. 

The site is in very good condition. The cover vegetation is thick and healthy. No signs of erosion were 

noted on the slopes or drainage ditches. The one possible burrow area that was noted near Pt D in March 

was repaired during the spring sampling event in April. 

If you have any questions on this inspection, please contact me.
