INTRODUCTION

S. T. Hudson Engineers, Inc. was retained to conduct a physical

characterization of the outfall pipelines and seeps at the CIBA-

GEIGY Corp., Newport Works facility in Newport, Delaware.

The inspection of the outfall area along the Christina River was

performed from October 7 to October 21, 1991 and will be referred

to as the "Present" inspection.

This study was conducted to locate and describe each exposed

outfall pipeline and seep along the CIBA-GEIGY property on the

Christina River. A complete physical characterization of the

outfall pipelines and seeps including pipeline/seep location,

invert elevation, material of construction, description of effluent

and/or material discharged, if any, location of known manholes and

stormwater inlets has been summarized in this report.

Prior to performing the recent survey, S. T. Hudson Engineers, Inc.

conducted a survey of the subject area from May 2 through May 11,

1990. This survey and report concentrated on the physical

characterization of the exposed outfall pipelines found along the

Christina River. A hydrographic survey of the River was performed

as part of the scope of the survey. The report was issued August

20, 1990.

S.T. HUDSON ENGINEERS, INC.

The purpose of the present inspection was to identify all visible

outfall pipelines and seeps. All observed outfall pipelines and

seeps have been surveyed and a plan showing their location and

cross section have been plotted on S. T. Hudson Engineers, Inc.

Drawing C-1292,

A diver's inspection was performed at the timber crib wall along

the south side of Building A-47. Photographs of this area along

with the outfall pipelines and seeps are included in this report.

EXECUTIVE SUMMARY

This report presents the findings of our visual site evaluation.

A thorough visual and physical characterization was made of the

river bank to locate and describe each exposed outfall pipeline and

seep.

A. Outfall Pipelines

A review of CIBA-GEIGY's Drawing entitled Newport Works Sewer

Map shows an extensive network of stormwater inlets, manholes

and outfalls. A total of twenty-six (26) outfall pipelines

(17 miscellaneous and 9 permitted) were found during our

visual inspection. Some of these lines have been abandoned,

rerouted and/or modified in the past according to CIBA-GEIGY.

Our investigation also included the tracing of selected

outfall pipelines back to its source by using a pipeline TV

camera, unless previously video taped or otherwise identified

by CIBA-GEIGY. The pipeline TV camera was operated by an

outside contractor selected by CIBA-GEIGY. The route of these

selected pipelines are plotted on S. T. Hudson Engineers, Inc.

1. Miscellaneous Outfall Pipelines

Outfall OF-1 is shown on CIBA-GEIGY Drawing No. NPA-15302 as

a storm water outfall pipeline. OF-1 was not included in this

survey by the request of CIBA-GEIGY. According to CIBA-GEIGY

Outfall OF-1 has been plugged, abandoned and no flow was

observed from the pipeline.

Outfall OF-2 is the old 001 outfall pipeline which was

abandoned when the new 001 outfall was installed and connected

to the first manhole. The end of the pipe is sealed. This

information was supplied by CIBA-GEIGY.

Outfall (OF-3,/- TV inspection of the 8" diameter vitrified clay

pipe was limited to approximately 6' into the pipe due to

debris. No flow was observed.

Outfalls OF-4 & 5 - According to CIBA-GEIGY these Outfalls (6"

diameter metal pipes) were connected to reservoirs l and 2

respectively and have been plugged and abandoned.

Outfall OF-6 - This outfall was found plugged but a low flow

in the 12" diameter vitrified clay pipe was evident. Effluent

was white and clear with a strong kerosene like odor.

o

AR3 I 0355 S.T. HUDSON ENGINEERS, INC.

Outfall OF-7 - OF-7 outfall was not found after river bank

defoliation. A 3 ft. section of pipe was found lying into the

river bank. It was not connected to anything and was removed.

outfall F-y was cut-off at the low water elevation and

approximately 19 ft. section of the 12" diameter metal pipe

was removed from the river. This pipe went to Bldg. A-22

where the pipe was sealed with brick/concrete and filled with

debris. No flow was observed.

/ \Outfall (OF-9J - A 6" diameter metal pipe. No flow was observed

at this time. This pipe was previously flushed to 43' + .

Origin unknown.

Outfall OF-10 - The OF-10 outfall was sealed with concrete.

Outfall OF-11 - The outfall end of OF-11 (5'-0" diameter

reinforced concrete pipe) is located off of the CIBA-GEIGY

property but the storm water pipeline runs under the north-

eastern section of the plant and comes under the Amtrak

railroad tracks to the north. Effluent was clear with no

odor. CIBA-GEIGY has no contribution to this pipeline.

Outfall OF-12 - An 8" diameter zinc pipe is plugged. No flow

was present at this time.

, INC.

Outfall OF-13 - A 4" diameter metal pipe. It is not known at

this time where this pipe goes or the condition of the pipe.

No flow was present at this time.

Outfall \OF-14 - A 5"' diameter metal pipe with an obstruction

25'+ from the south end. No flow was observed.

Outfall QF-157- A 6" diameter cast iron pipe with an obstruc-

tion 45' + from the south end. No flow was observed.

Outfall OF-16 - A 24" diameter concrete pipe that is located

off of CIBA-GEIGY property. This pipe appears to collect

stormwater from James Street. Effluent found at the time of

the survey was clear with no odor.

Outfalir"OF-17 y- Located between OF-11 and OF-16. It is

assumed that this is an outfall due to the location of a

concrete end wall. This area has fill up to within 4"± of the

top of the wall, with heavy vegetation growth above the wall.

Partial digging at the face of the wall did not uncover a

pipe.

At this time our inspection cannot rule out the possibility of

the presence or absence of additional outfall pipelines that

may be below the mean low water line of the river or that may

be buried below the river bottom.

2. Permitted Outfall Pipelines

Nine (9) of the twenty-six (26) outfalls found have been

identified by CIBA-GEIGY as permitted outfall pipelines and

are shown on CIBA-GEIGY Drawing No. NPA-15302 entitled Newport

Works Sewer Map and S. T. Hudson Engineers, Inc. File #C-1292

dated 11/6/91, Drawings 1 through 5.

Out of the (9) permitted outfall pipelines, two (2) lines 004

and 007 are reported by CIBA-GEIGY to be plugged and aban-

doned.

Outfall 009 is a double chambered storm water outfall that

runs thru the eastern end of the plant and comes under the

Amtrak Railroad tracks from the north.

At the time of inspection, flow was observed at five

outfalls (001, 002, 006, 008 and 009) and no flow was observed /

at outfalls 003 and 005. Outfall 004 is cut-off at the low

water line. The effluent at Outfalls 001 and 006 was clear

with no odor. At Outfalls 008 and 009 clear flow was observed \,

but there appeared to be staining of the immediate area. /

Outfall 002 is not on Ciba-Geigy property.


AR3I0358

B. Miscellaneous Structures

MS-1 appears to be an abandoned valve box structure with an

intake structure (MS-1A) approximately 25' outshore of MS-1.

MS-2 appears to be an abandoned river water intake structure,

however, this has not been confirmed.

MS-3 and MS-4 are both pump houses. MS-3 was abandoned when

MS-4 was installed. In addition, a 12" diameter river water

input line was installed in connection with MS-4. This line

supplies the three (3) reservoirs with river water. This

information was obtained from CIBA-GEIGY.

C. Seeps

Approximately twenty-six seeps were located at the time of

survey. The point of origin of these seeps is unknown. Some

seeps have color to the effluent, odor and/or have moderate to

heavy staining of the soil in the area of the seeps. Due to/

the makeup of the river bank, which appears to be old dis-

placed building structures and construction material, the1

location of the seeps could vary because of shifting of the,

river bank.

D. Timber Bulkhead

The full length of the timber bulkhead (200') was inspected

and found to have horizontal timbers and vertical piles in

relatively good condition. Some loss of fill was found. The

construction joint between Building A-47 and the concrete

topping of the bulkhead is open 1-1/2" maximum for a length of

55 feet.

SITE HISTORY

flR3!0363

A. Site History

1. Location

The CIBA-GEIGY Newport Plant is part of the EPA designat-

ed E. I. DuPont de Nemours Co., Inc. - Newport Superfund

Site (the "Site"). The Site is located in Newport, New

Castle County, Delaware along the banks of the Christina

River, adjacent to Interstate 95 and Delaware Route 141.

The Site apparently consists of the E. I. DuPont de

Nemours Co., Inc. Holly Run Plant, the CIBA-GEIGY Newport

Plant, and two landfills along the north and south banks

of the Christina River. The North Landfill is a seven

acre parcel of land bounded to the north by the E. I.

DuPont de Nemours Co., Inc. Holly Run Plant and the CIBA-

GEIGY Newport Plant and to the south by the Christina

River. The south landfill is a 15 acre parcel of land

bounded to the north by the Christina River, to the south

and southwest by automobile salvage yards, and on the

east by Old Airport Road and Basin Road

2. Past

The Site was originally owned by Henrik J.

Krebs from 1902 to 1929. Activities conducted

at the Site during this time included the

production of Lithopone, a white paint. In

1929, the Site was purchased by E. I. DuPont

de Nemours Co., Inc. which continued the

Lithopone production. Other activities initi-

ated during this time period included the

production of other lines of paint pigments

and chromium dioxide magnetic tape.

In 1984, CIBA-GEIGY bought the part of the

Site used to produce the paint pigments. The

remaining portion of the Site, the Holly Run

Plant and both landfills were retained by E.

I. DuPont de Nemours Co., Inc. The Holly Run

Plant continues to produce chromium dioxide

magnetic tape.

12

t

TA M U I U <3 0 t) S.T. HUDSON ENGINEERS, INC.

The two landfill areas were used primarily to

dispose of pigment muds; by-products of paint

production. Trash and such products as mag-

netic tape and thoriated nickel were also

disposed in the landfills. In 1973, the south

landfill was closed and capped with soil. In

1974, the north landfill was closed and capped

with clay. No landfilling has occurred at the

Site since 1974.

3. Present

The site consists of numerous buildings, which

include Manufacturing, Engineering, Milling,

Blending, Packaging and other such related

type buildings.

There are three fresh water reservoirs that

are used for fire fighting and other purposes.

Water is supplied to the reservoirs by a

recently installed 12" input line which takes

its water from the Christina River.

13

A K«J I U 366 S.T. HUDSON ENGINEERS, INC,

The southern edge of the property lies along

approximately 1200 feet of the Christina

River. The grade of the facility is approx-

imately 20 feet above the mean high water

elevation of the river. The river bank from

outfall 002 to outfall OF-13 drops off sharply

at an approximate 1 to 1 slope to the river.

The river bank was partially defoliated in the

Spring of 1991. Drainage is generally to

southeast towards the river. The intertidal

zone in this area lies approximately on a

gentle 4 to 1 slope and is composed primarily

of river mud, silt, rip-rap and occasional

aquatic vegetation.

From outfall OF-13 to outfall OF-11, the river

bank is composed of a concrete seawall and

timber bulkhead. Depths in the river vary

from relatively shallow along the bank to

approximately 12 feet below mean low water at

the center of the river channel.

SEEPS INSPECTION

AR3I0390

F. Seeps (SP)

An inspection of the visible seeps along the bank of the

Christina River was conducted from October 7, 1991 to October

21, 1991. Twenty six (26) seeps were located and surveyed.

The amount of flow, color and odor observed varied from seep

to seep.

One consistent observation noted was that active probing

(insertion of a small steel rod) of the seeps resulted in

either an increase of water and/or colored effluent discharge

or the cessation of all discharge from that seep. In addi-

tion, several probes into areas of the bank without seeps

resulted in the discharge of water and/or colored effluent.

It would appear that the bank, water and colored effluent all

exist in a dynamic state.

DIVER'S SURVEY OF THE TIMBERBULKHEAD AT BUILDING A-47

flR3IQ399

.

DIVER'S SURVEY OF THE TIMBER BULKHEAD AT BUILDING A-47

The structure consists of horizontal timbers, approximately 33

timber piles and concrete topping which holds back rock and stone

fill along the outshore (river face) of Building No. A-47. There

are no signs of steel or timber tie backs or spur piles.

For the purpose of this survey the west corner of the timber

retaining wall is referenced as Station 0+00 and continues east for

approximately two hundred and four feet (Station 2+04).

We found that the horizontal timbers which span between the

vertical timber piles are of various sizes and are in relatively

good condition.

The bottom course of the horizontal timbers are fully exposed from

approximately Station 0+80 to 1+90. The diver/engineer noted that

the rock fill consisted of bricks and angular stones with little to

no fines. It was possible to probe behind the timbers up to 2

foot. The stone and brick fill is falling out from beneath the

bottom course from 0+80 to 1+20. The remaining areas of the timber

retaining wall have stone and brick piled against the timber

bulkhead covering most of the bottom course with no loose fill.

41

K R 3 I 0 fy 0 0 ST'HUDSON ENGINEERS, INC.

The thirty three (33) timber piles which appear to be retaining the

stone fill and horizontal timbers are rotted and split at the top

1 to 2 feet, the remainder of the piles are typically in fair

condition.

The concrete topping is cracked vertically and horizontally along

the sloping face and is generally in fair to poor condition along

the sloping face. The top surface of the concrete topping is in

good condition with minor hairline cracks.

The construction joint between the brick Building No. A-47 and the

concrete topping (Station 1+36 to 1+93) is separated 1 to 1-1/2

inches and probed from 5 to 12 inches in depth. There are two

outfalls, Outfall 008 at Station 0+71 and OF-9 at Station 1+27,

located along the timber retaining wall. Outfall 007 Station 0+30

has been sealed with concrete.

See attached sketch and photographs for conditions of the timber

bulkhead.

IRecommendations;

We do not recommend any repairs at this time, but annual inspec-

tions should be conducted to insure that conditions do not

deteriorate. Also, we recommend that a program be set up to

monitor any changes to the construction joint between Building A-47

and the concrete topping.
