Region 2 serving the people of New Jersey,
New York, Puerto Rico and the U.S. Virgin Islands
• The Eighteen Mile Creek Corridor has a long history of industrial use dating back to the 19th Century
• New York State Department of Environmental Conservation (NYSDEC) investigated the Site between 1999 and 2010
• The Site was listed on EPA’s National Priority List in 2012

OU1 - Water Street Residential Properties & Flintkote demolition
EPA issued a final cleanup plan in 2013:
• Flintkote demolition
• Residential property acquisition and demolition due to flooding of PCBs
• Soil at the Water St. properties will be excavated during the OU2 cleanup

OU2 - Sediment in the Creek Corridor and soil at the Flintkote property, former United Paperboard property, the White Transportation property, and Upson Park
EPA issued a final cleanup plan in 2017:
• Bank-to-bank excavation of sediment
• A combination of excavation and capping at the aforementioned commercial properties
This remedy is in the design phase.

OU3 - Sediment in the Creek north of Lockport to Lake Ontario, and groundwater in the Creek Corridor
• EPA is currently conducting an investigation of the downstream areas of Eighteen Mile Creek
• Surface water, sediment, and soil samples were collected in summer 2018
• Investigation is being conducted in phases
![Page 11: Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting · Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting August 16, 2018 Region 2 serving the people of New Jersey, New](https://reader034.vdocument.in/reader034/viewer/2022050602/5fa9b70b1c39c26481658e9e/html5/thumbnails/11.jpg)

OU4 - addresses lead-contaminated soil at certain residential properties adjacent to the former Flintkote property
OU4 is the subject of this Public Meeting
![Page 12: Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting · Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting August 16, 2018 Region 2 serving the people of New Jersey, New](https://reader034.vdocument.in/reader034/viewer/2022050602/5fa9b70b1c39c26481658e9e/html5/thumbnails/12.jpg)

OU4
• Using a phased approach, EPA sampled residential properties east to the Flintkote property to determine if there were impacts from the Site
• Three separate sampling events were performed in 2017, totaling 27 properties
• 4 additional properties sampled in 2018
![Page 13: Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting · Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting August 16, 2018 Region 2 serving the people of New Jersey, New](https://reader034.vdocument.in/reader034/viewer/2022050602/5fa9b70b1c39c26481658e9e/html5/thumbnails/13.jpg)
OU4 Investigation Results
• Wide range of lead concentrations from 11 ppm to 1,610 ppm
• The highest concentrations of lead were found in subsurface soil from 6-18 inches
13
Region 2 serving the people of New Jersey,
New York, Puerto Rico and the U.S. Virgin Islands
• The results showed lead contamination at varying concentrations with no distinct pattern of distribution
![Page 14: Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting · Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting August 16, 2018 Region 2 serving the people of New Jersey, New](https://reader034.vdocument.in/reader034/viewer/2022050602/5fa9b70b1c39c26481658e9e/html5/thumbnails/14.jpg)
Human Health Risk Assessment
• Calculates risk to residents under current and future conditions
• Direct contact (eg. ingestion) with contaminated soil presented a future unacceptable risk to residents based on long-term chronic exposure over time

New York, Puerto Rico and the U.S. Virgin Islands

![Page 15: Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting · Eighteen Mile Creek Site OU4 Proposed Plan Public Meeting August 16, 2018 Region 2 serving the people of New Jersey, New](https://reader034.vdocument.in/reader034/viewer/2022050602/5fa9b70b1c39c26481658e9e/html5/thumbnails/15.jpg)
Reducing Potential Exposure
• Wash your hands thoroughly after coming into contact with soil
• Take your shoes off at the door to reduce dirt brought into the house
• Clean your home to keep it dust free as possible
• Bathe pets frequently to reduce dirt brought into the house
• Avoid activities that could disturb soil, including gardening

Proposed Plan
• Outlines the objectives of the cleanup
• Establishes soil cleanup levels
• Evaluates each cleanup option
• Proposes preferred cleanup option

Remedial Action Objectives
Specific goals developed to protect human health and the environment:
• Prevent potential current and future unacceptable risks to human health resulting from direct contact (eg. ingestion) with contaminated soil.
• Prevent migration of site contaminants from the residential properties to other areas.

18
The following two-tiered PRG has been identified for OU4:
Lead: • 400 ppm
• In addition to targeting detections of lead above 400 ppm, the average soil concentration across each residential property will be at or below 200 ppm
