Site Investigation (1982, 1986, 1987)
Bioassays were done in 1982 and 1986. The 1986 bioassay demonstrated toxicity. In
1987 Ohio EPA’s Division of Water Quality Monitoring and Assessment did screening
bioassays of two grab samples and a composite sample from the Sun outfall #001 in
conjunction with permit re-issuance. Samples, which all had a petroleum odor,
demonstrated toxicity. Further testing of effluents to verify toxicity was recommended.
(1991)
In 1991 Ohio EPA Division of Ground Water reviewed reports prepared by
Groundwater and Environmental Services, Inc. and concurred with the findings that oil
product was found in eight of nine monitoring wells in the area of the former
impoundment basin. The amounts ranged from 1.46 feet thick to 7.2 feet thick. Sun
Oil is currently recovering this product from the ground water. It is pumped from the
wells and routed through an oil/water separator and returned to the refining process.

This site was investigated as a part of the Ohio EPA Maumee Area of Concern
Project Phase II Site Assessments. Three areas of concern were identified -
groundwater contamination beneath Lake Charles (the former wastewater
impoundment), the leaded tank bottom disposal area, and contamination of Otter
Creek at the Sun Oil outfalls (NPDES permit). Further remedial investigation was
recommended.

Ohio EPA (funded in part by a grant from US EPA)
Remediation (1990-1993)
In 1993 Sun Oil completed construction of a new wastewater treatment facility which
began discharging to the city of Toledo’s sewer system. It Included an additional air
floatation unit, new equalization tanks and a new bio-treatment system. This
eliminated the discharge of process wastewater to Otter Creek.
Toledo Powdered Metals (1700 Landis Ave., Oregon)
(a.k.a. Republic Steel Corp., Metal Deck, Inc., Epic Metals Corp., Co-Bar Corp.)
Site History:
In 1953 this 20-acre property was purchased by the Republic Steel Corp (a.k.a.
Toledo Powdered Metals) and operated as a powdered metal fabricator until it was
sold in 1968. The next owner, Metal Deck, Inc., operated on the site from 1968 to
1976. Epic Metals Corp owned the property from 1976 until 1985. The current
operator is Co-Bar Corporation, which straightens coiled steel rods into rolled steel.
Site Investigation (1990, 1994, 1996)
In 1990 Bowser-Morner conducted a Phase I Site Assessment to determine the
current environmental conditions of the property. This study was updated in 1994.
Their 1990 assessment identified 4 areas of concern at the site: 1) cooling lubricants
waste, 2) waste drums, 3) underground storage tanks (USTs), and 4) transformers.
In the 1994 update it was noted that the waste drums and USTs were removed and
the transformers were drained and one was refilled with non-PCB fluids. Concern #1
appeared not to have been addressed. The 1994 update concluded that there was no
