SECTION 1 INTRODUCTION
On 10 April 2002, RoyF. Weston, Inc., (WESTON®) Superfund Technical Assessment and Response
Team (START) was directed by the United States Environmental Protection Agency (U.S. EPA) to assist
U.S. EPA On-Scene Coordinator (OSC) Jason El-Zein in conducting emergency response activities at the
River Rouge Oil Spill Site in Dearborn and Detroit, Wayne Coimty, Michigan. The emergency response activities were conducted under Technical Direction Document (TDD) number S05-0204-010.
As a part of the ongoing investigation into the source ofthe oil spilled into the River Rouge in April 2002, numerous facilities in Dearborn and Detroit, Michigan, were inspected, and each facility’s Spill Prevention
Countermeasures and Control (SPCC) Plan was reviewed. During site inspection activities, samples were collected by START and the U.S. Coast Guard (USCG) from sewers, tanks, and facility sumps and submitted for chemical analysis. START samples were submitted to the U.S. EPA Emergency Response
Team (ERT) contracted laboratory and to WESTON subcontracted laboratories. The majority of samples
START collected were split with the USCG. USCG-collected samples and USCG split samples from
START were analyzed by the Coast Guard Oil Identification Laboratory (COIL). Results from USCG sampling are provided in the Spill Response Site Files. Sample Plans, Sample Quality Assurance Project
Plans (QAPPs), and ERT and WESTON subcontracted laboratory QAPPs are provided in the Spill
Response Site Files.

Potential sources of the spilled oil were identified as those facilities that handled the type and quantity of oil found in the river and that had a potential migration or discharge pathway to the suspected spill or release area on the River Rouge. The objective of this site inspection was to gather facility-specific information to determine if the Rouge Steel Company / Ford Motor Company (Rouge Steel / Ford
Complex) is a potentially responsibly party (PRP) to the release that occurred on the River Rouge and
Detroit River in April 2002.
Specific tasks of the site inspection were as follows;
• Compile background information, including analytical data fi'om samples collected by START and the USCG, regarding the quantity and kind of oily wastes or types of products present at the facility;
• Conduct an on-site reconnaissance and document existing volumes and types of oils and oily wastes at the site;
• Collect samples to determine if the oils and oily wastes at this site match the oils collected from the River Rouge;
• Evaluate the potential for releases ofoily materials or products fi-om the site and their potential off-site migration pathways;
• Conduct reviews of the facility’s SPCC Plan and determine if the facility is environmentally compliant or is a risk for spillage;
• Prepare a Site Inspection Report that documents the findings.

SITE BACKGROUND
2.1 SITE DESCRIPTION
The Rouge Steel / Ford Complex is located at 3001 Miller Road in Dearborn, Michigan (Attachment A-1,
Topographic Map and A-2, Aerial Photograph). The geographical coordinates for the area of the site included in this investigation are latitude 42° 18'41" N and longitude 83°09'40" W. The facility is located within an industrial area and occupies approximately 900 acres. The facility is bordered on the east by
Miller Road, to the south by the River Rouge and the Dix Avenue Bridge, to the north by 1-94 and Rotunda
Drive, and to the west by Schaefer Road. The River Rouge, a navigable waterway, is located to the south of the Site. A Facility Layout Map is included in Attachment B.
The Rouge Steel / Ford Complex consists oftwo companies operating within the same facility, the Rouge
Steel Company (RSC) and the Ford Motor Company (Ford Motor). These companies share the facility with separate operations and buildings. RSC is a My integrated steel mill consisting ofthree blast furnaces
(for iron making), two basic oxygen furnaces (for steel making), two ladle metallurgical facilities, three continuous casting machines, one hot strip mill, and one cold roll mill. The RSC portion of the facility also includes three decommissioned coke oven batteries, a decommissioned powerhouse, and a byproducts recovery plant. Ford Motor operates several process buildings within the Rouge Steel/Ford Complex including a frame plant, engine plant, stamping plant, assembly plant, and a wastewater treatment plant (WWTP).

According to a U. S. EP A Region V draft Multimedia Inspection Report (inspection was performed in the
fall of1998), there are approximately 86 aboveground storage tanks (ASTs) with a combined capacity of
2,865,520 gallons; two 15,000 -gallon underground storage tanks (USTs); and approximately 500 small containers including transformers, drums, totes, and lugs containing oil or oily wastes located at the facility.
The facility has a combined total oil storage capacity of approximately 2,965,520 gallons.
2.2 SITE HISTORY
The Rouge Steel / Ford Complex, was formerly part of the Ford Motor Company - Rouge Complex, has operated at the present location since 1919. Ownership of the steel manufacturing processes and operations were transferred entirely to RSC in 1989. Ford Motor continues to maintain automobile manufacturing operations at the sprawling complex.
Between 1989 and 1999, RSC and Ford Motor jointly owned a coal-fired powerhouse, which was located on the Rouge facility. This plant was decommissioned in February 1999 as a direct result of a fire.
The powerhouse is currently being dismantled.
Coke making operations at the on-site coke oven batteries ceased in 1988. Presently, RSC purchases its coke for use in the blast furnaces from New Boston Coke Company in Portsmouth, Ohio.

SECTION 3
ENVIRONMENTAL INVESTIGATION ACTIVITIES
3.1 SITE OBSERVATIONS AND SAMPLING
Between 10 April and 3 May 2002, a Field Investigative Team (FIT) composed of personnel from U.S.
EPA, USCG, Michigan Department of Environmental Quality (MDEQ), and START contractors
conducted several inspections of the Rouge Steel / Ford Complex. Mr. Donald Windeler, Manager of the
Environmental Engineering Department forRSC, and Mr. David O’Connor, Supervisor ofEnvironmental
Services for Ford Motor Company, accompanied the inspection teams as his respective company’s
representative. The inspections focused on the Ford Tailrace (Outfall 006) and the associated storm sewer
lines, on the sanitary sewers that are tributary to the Miller Lift Station (Outfall 021), on the on-site oil
polishing lagoons (Outfall 001) and their discharge to the River Rouge and on the Ford Boat Slip and all
associated outfalls. Select photo documentation and a photo location map for this report is provided in
Attachment C and Attachment D, respectively. A complete photo log for this site is available in the Spill
Response Site Files. A Sample Location Map is provided in Attachment E, and a summary table of sample results is provided in Attachment F.
Ford Trailrace lOutfall 006)
The Ford Tailrace serves as a storm sewer and discharge route for cooling water and excess water drawn from the Detroit River for use in the Rouge Steel / Ford Complex. The discharge point for the Ford

Tailrace is Outfall 006 (Attachment C, Photo 1), which has a discharge rate between 60 and 90 million gallons per day (as reported by Mr. Donald Windeler, RSC, April 2002). The drainage area for the Ford
Tailrace is confined to the southeast portion of the Rouge Steel / Ford Complex (Attachment B). This area was surveyed, and three potential sources of oil were indicated; an abandoned gas holding tank; a decommissioned powerhouse; and a catch basin in the old coal storage area.
The abandoned gas holding tank, located in the southeast comer of the complex, is currently being dismantled. During the dismantling process, waste oil was discovered and removed fi-om the tank and stored in a fractionation tank for disposal. START collected a sample of this oil (ROS-J J-083) and oil from a sump located at the base of the gas holding tank (ROS-JJ-084) (Attachment C, Photo 77 & 78).
Neither sample matched the oil released into the River Rouge in April 2002.
The second potential source area within the Ford Tailrace drainage area was the decommissioned powerhouse located in the eastern portion of Rouge Steel. The Tailrace mns directly under the powerhouse. U.S. EPA was concerned that oil and material from the fire at the powerhouse in 1999 could have entered the Tailrace and discharged to the River Rouge. Ford Motor provided manifests detailing the quantities and type ofmaterials removed from the powerhouse as a part of its demolition. U.S. EPA’s requests to inspect the powerhouse were postponed by active demolition activities; however. Ford Motor conducted an inspection ofthe areas of concern within the powerhouse and submitted a written report with photos which is available in the Spill Response Site Files. Any significant accumulations of oil or areas of oil staining did not report Ford Motor.

The third potential source area within the Ford Tailrace drainage area was a catch basin located in the southeast comer of the Rouge Steel / Ford Complex. Oil staining was observed in and around the catch basin in the old coal storage area near the parking area for Doetsch Industrial Services, contractors for
RSC (Attachment C, Photo 26). Two vacuum boxes (Attachment C, Photo 24) filled with oily wastes were located in the same area. The vacuum boxes were open to the environment. Sample RSROT-01 was collected by START at this location (Attachment C, Photo 36) but was not analyzed; however, the
USCG spht sample 02-112-13 was analyzed. Although the sample did not match the oil in the river, it did contain a key contaminant present in the spill material.
At no time was any free oil observed in the Ford Tailrace or its tributary storm sewers. However, a slight sheen was observed in the wet well (Attachment C, Photo 25) on the Ford Tailrace (Outfall 006). This sheen was sampled by START (ROS-TJ-055) and the USCG (02-127-1). The sample the USCG collected was analyzed by COIL but did not match the oil released to the River Rouge.
Sanitary Sewers (Outfall 0211
After completing the inspections ofthe Ford Tailrace drainage area, START began inspecting the sanitary sewer lines within the Rouge Steel / Ford Complex. The inspections of the sanitary sewer lines tributary to the Miller Lift Station identified a single location with an accumulation ofoil. START collected samples
RS-01 and RS-02 from this sanitary sewer, located 20 feet northwest of the Rouge Steel Training Center
(Attachment C, Photo 29). This material did not match the oil released to the River Rouge.

Oil Polishing Lagoons (Outfall 001)
Following the inspections of the sanitary sewers, START inspected and conducted sampling at the Oil
Polishing Lagoons (also referred to as Schaefer Road WWTP). The Oil Polishing Lagoons serve as an oil treatment process for RSC. Wastewater containing oil is discharged into two clarifiers where oil is skimmed from the surface. Water is then pumped into the first of two lagoons where the water passes through two baffles to contain any residual oil. Water then passes through the second lagoon where four additional containment structures serve to contain oil prior to the lagoons’ discharge to the River Rouge via
Outfall 001. Samples collected from an oil skimmer at Outfall 001 (ROS-CG-056) and the second lagoon’s discharge to the river (ROS-CG-057) did not match the oil spilled in the river (Attachment C,
Photo 10). TheUSCG collected a sample (02-110-13) from the clarifying pools; this sample did contain the key contaminant present in the oil spilled into the River Rouge.
The U.S. EPA noted several deficiencies in the oil polishing lagoon’s operation, including the following:
• The presence of vortices at the final containment baffle (Attachment C, Photo 54);
• Bypass routes through a containment boom (Attachment C, Photo 56 & 57);
• Poor attachment of the edges of a boom allowing oil to flow through the system (Attachment C, Photo 61 & 67);
Nonfunctioning oil skimmers (Attachment C, Photo 63).

Ford Boat Slip and Associated Outfalls
START inspections found that Ford Motor operates and maintains oil recovery systems at the Roulo Creek
Outfall (Outfall 017) to the Ford Boat Slip. The Roulo Creek Enclosure serves as the discharge point for the North Rouge WWTP (Outfall 004E) and is a combined sewer overflow discharge point for the City of Dearborn. Neither of the samples collected from the wet well at Outfall 004E (ROS-CG-060) and the
North Rouge WWTP clarifier (ROS-USCG-001 & ROS-TJ-104) matched the oil released into the River
Rouge in April 2002.
Sampling Summary
START collected 18 samples (and one duplicate) from the Rouge Steel / Ford Complex (six of these samples were splits the USCG provided). None of these samples matched the oil released into the River
Rouge. The USCG collected 42 samples from various areas within the Rouge Steel / Ford Complex. The
USCG collected several samples from aroimd Outfall 006 following observations of oil staining along the river banks in the vicinity of Outfall 006. Of these samples, sample 02-101-8, comprised of pieces of sorbent boom deployed around Outfall 006, was found to match to oil released into the River Rouge in
April 2002. However, this apparent match maybe associated with oil already present in the river that has accumulated around the outfall. Oneother sample, sample 02-112-1, the USCG collected contained the key contaminant found in the River Rouge but was not a match for the oil spilled into the river in April 2002.
This sample was collected from the Rouge Steel #2 Tandem Mill sump (Attachment C, Photo 32).

As part ofthe U.S. EPA’s ongoing civil investigation, START collected eight additional samples (all were
split with USCG) from VAC-ALL pump tmcks transporting material from various areas within the RSC
portion of the complex to U.S. Liquids. Analytical results indicated that the samples did not match the oil
released into the River Rouge.
MDEQ investigations indicated an oily deposit on the concrete River Rouge channel below Outfall 001.
ERT’s analysis of this material (sample ROS-EF-061) indicated that it was not a match to tlie oil released
into the River Rouge and Detroit River in April 2002.
3.2 SPCC PLAN REVIEW
An SPCC Plan review was not performed at this facility because a review was performed on 30
September 1998. The SPCC review is provided in the 26 February 1999 draft Multimedia Inspection
Report, which is located in the Spill Response Site Files.
3.3 MIGRATION PATHWAY DISCUSSION
The Rouge Steel / Ford Complex encompasses several locations within the Ford River Rouge Complex
Subdistrict (Attachment G-1). Wastewater and storm water from this facility will follow a number of pathways (Attachment G-2). Generally, waste streams from the western area ofthe subdistrict flow west to the Schaefer Road WWTP (also referred to as the Oil Polishing Lagoons), which discharges into the
River Rouge at Outfall 001, located about 1,200 feet upstream from the Schaefer Highway Bridge. Waste

This document was prepared by Roy F. Weston, Inc., expressly for U.S. EPA. It shall not be released or disclosed in whole or in part without the express, written permission of U.S. EPA. Site Inspection Report Rouge Steel / Ford Complex Section: 3 Revision: 0 Date: 23 July 2002 Page: 3-7 of 10 streams originating from the central area of the subdistrict are generally treated and discharged into the Ford
Boat Slip at Outfalls 004a through 004e or Outfall 002, located approximately 1,500 feet upstream from the Dix Road Bridge. Waste streams from the southeast quadrant of the facility, including the gas holding tank, flow through the Ford Tailrace to Outfall 006, located approximately 1,150 feet downstream of the
Dix Street Bridge and 50 feet upstream of Outfall 021.
Wastewater and storm water discharges from specific Rouge Steel / Ford Complex facilities are listed below. Oil present in these waste streams would be released into the River Rouge.
Pretreated process wastewater from the cold mill and the hot strip mill discharges into the River Rouge at Outfall 001.
Pretreated process wastewater from the continuous caster along with some process wastewater from the cold mill discharges into the River Rouge at Outfall 002a.
Storm water, pretreated process wastewater from blast furnace B, and noncontact cooling water from the power generation plant discharge into the Ford Boat Slip at Outfall 004b.
Some process wastewater and noncontact cooling water from the basic oxygen furnace discharge into the Ford Boat Slip at Outfall 004c.
Noncontact cooling water from the cold mill discharges into the Ford Boat Slip at Outfall 004d.
Storm water and noncontact cooling water from blast furnace C discharge into the Roulo Creek Enclosure at Outfall 004e; the Roulo Creek Enclosure discharges into the Ford Boat Slip at Outfall 017.

• Storm water and noncontact cooling water from the power house flow through the Ford Tailrace and discharge into the River Rouge at Outfall 006.
In addition to the waste streams listed above, some sanitary wastewater from Rouge Steel flows through
a 3-foot 6-inch line into the East Dearborn Interceptor upstream of the Miller Road Pumping Station.
Attachment H-1 illustrates various operating scenarios at the Miller Road Pumping Station. As depicted
in the dry weather flow scenario, sewage in the interceptor usually flows past the Miller Road Pumping I Station. Under this scenario, the pumps are off, and there is no flow in the pump discharge pipe, which terminates at the drop manhole (Location No. 6 on Attachment H-1). Sewage flows by gravity into the
influent junction box (Location No. 2 on Attachment H-1) and backs up into the wet well of the pumping
station. A flap gate, located immediately downstream ofthe Parshall flume (Location No. 3 on Attachment
H-1), prevents backflow in the interceptor.
Approximately 1,600 feet dovmstream of the pumping station, the East Dearborn Interceptor merges with
the 12-foot 9-inch Oakwood Interceptor, which discharges into the Detroit WWTP. During wet weather,
water surface elevations in the Oakwood Interceptor and its tributaries, including the East Dearborn
Interceptor, rise in response to rising wet well elevations at the Detroit WWTP. When the water surface
elevation in the downstream portion of the interceptor rises above approximately 83 feet (Detroit datum),
the flap gate downstream of the Parshall flume closes, isolating the downstream portion of the interceptor
from the upstream portion.
The pumping station turns on automatically, lifting the wastewater about 20 feet and discharging it into a
60-inch-diameter gravity flow sewer that terminates at a drop structure (see the wet weather flow scenario

This document was prepared by Roy F. Weston, Inc., expressly for U.S. EPA. It shall not be released or disclosed in whole or in part without the express, written pernission of U.k EPA. Site Inspection Report Rouge Steel / Ford Complex Section: 3 Revision: 0 Date: 23 July 2002 Page: 3-9 of 10 on Attachment H-1). At the drop manhole (Location No. 6 on Attachment H-1), sewage falls into the downstream portion of the East Dearborn Interceptor. When the flow rate in the interceptor is less than the pump capacity, the pumps draw down the water surface elevation in the wet well and the upper portion of the interceptor.
Conversely, when the flow rate in the interceptor exceeds the pump capacity, the water surface elevation in the upper portion of the interceptor will continue to rise. If the water surface elevation in the upper part ofthe interceptor exceeds the elevation in the lower part, the flap gate will open, and wastewater will flow by gravity through the Parshall flume into the lower portion ofthe interceptor. Under these circumstances, the flow pattern through the pumping station will be a combination ofthe dry weather and wet weather flow patterns shown on Attachment H-1.
Combined sewage in the East Dearborn Interceptor can overflow a weir located near the drop manhole
(refer to Attachment H-2) and discharge into the River Rouge at Outfall 021, located approximately 1,200 feet downstream of the Dix Street Bridge and approximately 50 feet downstream of Outfall 006
(Attachment G-2). If the water surface elevation at the drop manhole exceeds the weir crest elevation
(96.7 feet Detroit datum) and the pumps are on, combined sewage in the interceptor will overflow into the outfall pipe and discharge into the River Rouge. Attachment H-1 depicts the flow pathway through the pumping station under this overflow scenario.
Hydraulic modeling and level sensor data indicate that combined sewer overflows did not occur at the
Miller Road Pumping Station during the first halfof April 2002. Level data fi-om the B-50 sensor recorded

This document was prepared by Roy F. Weston, Inc., expressly for U.S. ERA. It shall not be released or disclosed in whole or in part without the express, written permission of U.S. ERA. Site Inspection Report Rouge Steel / Ford Complex Section: 3 Revision; 0 Date; 23 July 2002 Page; 3-10 of 10 on 13 April at 6:30 AM show that the maximum water surface elevation from 1 April through 15 April at that location was 94.8 feet (Detroit datum). The flow rate in the East Dearborn Interceptor at that time was about 24 cubic feet per second. Assuming a roughness coefficient of 0.015 and using Manning’s equation, the calculated head loss from the confluence of the Oakwood and East Dearborn Interceptors to the drop manhole would be about 0.1 feet (calculations available in the Spill Response Site Files). Thus, the maximum water surface elevation at the drop manhole at that time was estimated at 95 feet (Detroit datum), approximately 1.5 feet below the weir crest elevation.
These hydraulic observations are consistent with visual observations of the sewer system at the pumping station and the nearby Eagle Street Underpass. FIT personnel, who entered the drop manhole and overflow manhole at the pumping station on 1 May2002, did not observe any oil downstream of the weirs.
(Refer to the Spill Response Site Files Section 3-J for photographs and videotape of the sewer entry).
Furthermore, no flooding was observed by City ofDearborn personnel at the Eagle Street underpass during the spill incident (personal conversations with Mr. Steven Sienkiewicz on 8 May and Mr. Richard Reska on 22 May). Runoff from the Eagle Street Underpass flows into a sanitary sewer tributary to the East
Dearborn Interceptor. Because the grade elevation at the lowest point under the bridge is approximately
94 feet (Detroit datum), an overflow at the pumping station would necessarily be signified by flooding at the underpass. Therefore, oil discharged from Rouge Steel into the storm sewers presented above would have discharged to the River Rouge at the outfalls noted; however, sanitary discharge into the East
Dearborn Interceptor would not have been discharged into the River Rouge.

SECTION 4
FINDINGS AND CONCLUSIONS
The U.S. EPA has established three primaiy criteria for determining if a specific facihty may be accountable for the River Rouge oil spill. The criteria consist of the following:
• A positive match on the oil analysis; • Adequate oil handling volumes (greater than 100,000 gallons); • A pathway to the suspected release points in the River Rouge.
START and MDEQ collected a total of 28 oil samples, which were analyzed by ERT. None of these samples were considered a match with the oil spilled into the River Rouge in April 2002. The USCG collected and submitted a total of 42 samples to COIL for analysis. Three of the samples were found to contain a key contaminant linked to the oil in the river (02-110-13,02-112-1, and 02-112-13); however, analytical results for some samples are still pending. The single oil sample that matched oil in the river (02-
101-8) was taken from the boom in the river, just outside of Outfall 006. These results indicate that some of the oil in the Rouge Steel / Ford Complex and in the river had similar trace contaminants, but none of the oil sampled inside of the complex matched the oil in the river.
Review of oil storage and handling records indicated that adequate volumes were present at the facility to account for a major spill. Hydraulic calculations of sewer configurations and wet weather scenarios indicated that oil spills could reach the River Rouge through outfalls and combined sewers imder rare conditions but not through sanitary sewer lines. Visual inspections found several containment barriers that

were not sound. Therefore, based on these findings, the Rouge Complex cannot be eliminated as a
suspected source of the River Rouge oil spill.
