STAGE II INTRODUCTION

CHAPTER 1: Stage II Introduction

Introduction

The International Joint Commission (IJC) has identified 43 Areas of Concern (AOC) in the Great Lakes
drainage basin where pollutants are impairing beneficial uses of a waterbody. Eighteenmile Creek is one
of these AOCs because: 1) past municipal and industrial discharges have contaminated the creek and its
bottom sediment; 2) the disposal of waste and; 3) the use of pesticides.

Under the 1987 Amendments to the United States – Canada Great Lakes Water Quality Agreement
(GLWQA), Remedial Action Plans (RAPS) are to be developed by the States and Province of Ontario
for the AOCs under their jurisdiction. The plans are to serve as an important step toward restoring and
maintaining the chemical, physical, and biological integrity of the AOC and the entire Great Lakes
Basin Ecosystem. They are to define environmental problems in the AOC, identify remedial measures
needed to restore beneficial uses, and identify a monitoring process needed to track remediation
progress. The RAP is to be submitted to the IJC in three stages:

1) When the problem has been defined;
2) When remedial measures are selected and;
3) When monitoring indicates beneficial uses have been restored

At the inception of the AOC program, the New York State Department of Environmental Conservation
(NYSDEC) was the lead agency for the Eighteenmile Creek RAP. NYSDEC’s Division of Water, in
concert with other NYSDEC Divisions, was responsible for the development of a combined Stage I/II
RAP document which was completed in August 1997. The Stage I/II RAP provided an impressive array
of water quality monitoring and sediment sampling data that document contaminant levels resulting in
beneficial use impairments. The document confirmed the restrictions on fish and wildlife consumption,
degradation of benthos, and restrictions on dredging activities use impairments. Bird or animal
deformities or reproductive problems was judged as a likely impairment and the status of degradation of
fish and wildlife populations, fish tumors and other deformities, and degradation of phytoplankton and
zooplankton populations were classified as unknown. Given the existing data gaps at the time, the
document also lacked a number of crucial components required to be considered a complete Stage II
RAP: an evaluation of in-place remedial measures; an evaluation of alternative additional measures and;
selection of additional remedial measures required to restore beneficial uses. This Stage II RAP Update
serves to satisfy the completion of these missing plan components.

As of January 1, 2005, the Niagara County Soil & Water Conservation District (NCSWCD) has
assumed the role of coordinator for Eighteenmile Creek’s RAP. NCSWCD also assists the Eighteenmile
Creek Remedial Advisory Committee (RAC) by facilitating their quarterly meetings and providing staff
support towards the implementation of the creek’s RAP. The Eighteenmile Creek RAC is a group of
local officials, landowners, and stakeholders selected by the commissioner of the NYSDEC to provide a
balanced representation of various segments of the community along the creek. Initially, the RAC
worked cooperatively with the NYSDEC to organize, develop and review the RAP and create public
awareness and support for Eighteenmile Creek. Additionally, it is the responsibility of the RAC to:

 Advise in identifying and updating priorities for RAP implementation activities;
Page | 2
 Advise in the preparation and approval of RAP documents;
 Assist in building a stakeholder base for implementation of RAP recommendations;
 Review and comment on current environmental initiatives and issues affecting the RAP;
 Assist in developing and seeking funding for a list of activities requiring funding; and
 Assist with social and economic impacts of RAP implementation.

The RAC was instrumental in the development of the original RAP, the Stage II Update and the
implementation of various public outreach activities over the years. These activities have maintained the
continued involvement and interest of the organizations represented on the RAC and built general
interest and support for the RAP in the overall community.

NCSWCD, as the lead agency, intends to use this RAP as a management document to guide and
coordinate remedial actions for Eighteenmile Creek initiated by various agencies to create and improved
federal, state, and local partnership in addressing the goals of the plan. A timeline of significant
investigations and events can be found in Appendix C of this document.

1.1 AREA OF CONCERN CHARACTERISTICS

1.1.1 Area of Concern Background

The Eighteenmile Creek AOC is located in Niagara County, New York (see Figure1-1). The creek flows
generally north through central Niagara County and discharges via Olcott Harbor into Lake Ontario,
approximately 18 miles east of the mouth of the Niagara River. The AOC includes Olcott Harbor and
extends upstream to the farthest point at which backwater conditions exist during Lake Ontario’s highest
monthly average lake level. This point is located just downstream of Burt Dam, approximately 2 miles
south of Olcott Harbor. This portion of the watershed is a unique gorge habitat that attracts recreational
boaters, anglers, birders, and waterfowl hunters.

Eighteenmile Creek was designated as an AOC because of water quality and bottom sediment issues
associated with past industrial and municipal discharge practices, the disposal of waste and the use of
pesticides. Over the years, numerous contaminants have been identified in creek sediments which have a
detrimental effect to the AOC and Lake Ontario. These contaminants include but are not limited to;
Polychlorinated Biphenyls (PCBs); Mercury; Dioxins and Furans; Dieldrin; Mirex; DDT; Lead; and
Copper. Sediments contaminated with these substances have contributed to restrictions on fish and
wildlife consumption, degradation of benthic organisms, and restrictions on dredging activities in the
AOC. It is also suspected that these contaminated sediments contribute to a degradation of fish and
wildlife populations, the presence of fish tumors, and the prevalence of bird and animal deformities or
reproductive problems.

Only a small portion of the Eighteenmile Creek basin was originally designated an AOC by the IJC.
However, for two reasons, since the Eighteenmile Creek RAP process began, the AOC has been
considered the impact area and the upper watershed as the source area (NYSDEC 1997). First, except
for potential impacts from agricultural operations adjacent to the current AOC boundary, there are no
documented sources or source areas of contamination within the AOC. Second, various investigations
conducted over the past 35 years have suggested that contaminants may be entering the AOC from
upstream areas. Specifically, PCBs, copper, lead, and other metals have been found in creek sediment
