Current Status

EPA is currently preparing an agreement to implement the remedy selected in the Record of Decision
(ROD). The selected remedy for the seven areas of the Site include excavation and disposal of
soil/sediment, containment
with soil, clay, and/or armor
caps, and monitored
natural recovery.

The EPA issued the ROD
for the Site in September
2013. Prior to issuing the
ROD, EPA completed a
Proposed Plan to propose
a preferred remedy for site
cleanup. The Proposed
Plan summarizes the
alternatives evaluated for
the Site, highlighting the
key factors that led to
identifying the preferred
alternative.

A 30-day public comment

period was held June 20 to July 21, 2013, to receive comments from the public on the preferred cleanup
remedy. EPA also held a public meeting on July 11, 2013, to present the preferred remedy and to
receive comments from the community.

Background

The Star Lake Canal Superfund Site (Site) is located in Port Neches, Texas, an industrial city adjacent to
the Neches River in East Texas in the center of the Beaumont-Orange-Port Arthur Golden Triangle (see
the "Site Aerial Photograph" below).

The Site is currently defined as the lengths of two industrial canals, the Star Lake Canal and the Jefferson
Canal, from their origins to the Neches River. The Star Lake Canal joins the Jefferson Canal in an area
between State Highway 366 and Sara Jane Road (a.k.a. Atlantic Highway).

STAR LAKE CANAL

1

EPA Publication Date: 7/10/2015


-------
The Jefferson Canal was constructed in the late 1940's as an industrial wastewater and stormwater
outfall. The Star Lake Canal was constructed after 1948 for the same purpose. Both canals are currently
being utilized for industrial and stormwater purposes by chemical and other manufacturing facilities.

The Site consists of surface water and sediments in the Star Lake Canal, Jefferson Canal, and the
Molasses Bayou and Wetland. These wetlands are habitats used by State-designated threatened
species.

From the confluence of
the Molasses Bayou,

Star Lake Canal, and
Neches River, surface
water flows down the
Neches River
approximately 3 >2 miles
to Sabine Lake. Sabine
Lake is used as a fishery
and produced more than

1	million pounds offish
and shellfish in 1996.

The land use
surrounding the Site is
industrial, residential,
and recreational.

The population within
one-mile of the Site is
5,604 persons. The

population of the City of Port Neches is approximately 14,452. Other communities in the area include
Groves, Nederland, and Port Arthur.

The EPA entered into an Administrative Order on Consent (AOC) with Huntsman Petrochemical
Corporation and Chevron Environmental Management Corporation (the PRPs) to perform and finance the
Remedial investigation and Feasibility Study (RI/FS) for the Site. The AOC was signed on December 22,
2005. The purpose of the RI/FS is to determine the nature and extent of contamination and to gather
sufficient information about the Site to support an informed risk management decision regarding which
remedy is the most appropriate for the Site. The Tier I Ri report has been approved by the EPA, the Tier

2	Ri Report was completed in August 2011, and the Final FS Report was delivered on June 5, 2012.

Benefits

Cleanup of the Site will ensure the protection of the environment (see Health Considerations below).

Site Map

Wastes and Volumes

The Jefferson and Star Lake Canals received industrial wastewater and stormwater discharges from
chemical and other manufacturing facilities for a number of years. This Site was added to the National
Priorities List based on evidence that hazardous substances, including chromium, copper, polynuclear
aromatic hydrocarbons, and polychlorinated biphenyls have migrated or could potentially migrate to
Molasses Bayou, Star Lake Canal, Neches River, Sabine Lake, and their associated wetlands.
Pentachlorophenol and toxaphene have been found in the sediments of the Jefferson Canal.

The areas of contaminated materials currently at the Site are presented in the Rl Reports.

Health Considerations

Human Health and Ecological Risk Assessments are an integral part of the Remedial Investigation and
Feasibility Study (RI/FS). A Human Health Risk Assessment estimates the current and possible future
risks if no action were taken to clean up a site. The risk assessment determined that there is no
unacceptable risk to human health at the Site.

An Ecological Risk Assessment is defined as a process that evaluates the likelihood that adverse
ecological effects are occurring or may occur as a result of exposure to Site contaminants. Adverse
responses can range from non-lethal chronic effects in individual organisms to a loss of ecosystem
function. The risk assessment has determined that there is a high probability of ecological toxicity to small
animals and insects, and to animals higher in the food chain. A remedial action selected in the Record of
Decision (ROD) will to address this ecological risk.

Record of Decision 	

The final remedy (cleanup alternative) for a site is published in a ROD. The EPA issued the ROD for the
Site in September 2013 in consultation with TCEQ and following consideration of the public comments.
The selected remedy for the seven areas of the Site included excavation and disposal of soil and/or
sediment, containment with soil, clay, and/or armor caps, and monitored natural recovery. A Remedial
Design phase, including additional field work, will be completed before Site construction of the remedy
can begin.

Community Involvement	

Proposed Plan:	June 2013

Public Comment Period:June 20, 2013 to July 21, 2013

Public Meeting:	July 11, 2013

Community involvement is the name the EPA uses to identify its process for engaging in dialogue and
collaboration with communities affected by Superfund sites. The mission of the Superfund Community
Involvement Program is to advocate and strengthen early and meaningful community participation during
the EPA's remedial activities at a Site. The EPA's community involvement program is founded on the
belief that people have a right to know what the EPA is doing in their community and to have a say in it.
Its purpose is to give people the opportunity to become involved in the EPA's activities and to help shape
the decisions that are made at a site.

Fact sheets will be prepared as necessary during the planning and implementation of the RI/FS. These
fact sheets will be filed at the Site's repository and distributed to people on the mailing list. Anyone who
desires to be placed on the mailing list to receive current information about the Site is encouraged to call
1-800-533-3508. This Site Status Summary can be found on the internet at the following address:

The purpose of the Site Repository is to provide the public a location near their community to review and
copy background and current information about the Site. The Site's repository is located at:
