Federal Register Notice:  September 13, 2001 (PDF) (9 pp, 193K, About PDF)

Conditions at Proposal (June 14, 2001): The MacKenzie Chemical Works, Inc. (MacKenzie) site is located at One Cordello Avenue in Central Islip, Suffolk County, New York. The site is located within a residential/light commercial area of Central Islip and is bounded to the north by the Long Island Rail Road, to the east by private property, to the south by Railroad Avenue, and to the west by Cordello Avenue. The property encompasses approximately 1.4 acres and houses three 1-story block buildings and one 2-story block building.

MacKenzie used the property from 1948 to 1987 for the manufacture of various chemical products, including fuel additives and metal acetylacetonates. Historically, the Suffolk County Department of Health Services (SCDHS) and the Suffolk County Fire Department have documented poor housekeeping and operational procedures. Spills, explosions and fires have occurred at the facility, including a methyl ethyl ketone (MEK) spill in 1977, a nitrous oxide release in 1978, and an MEK spill/fire in 1979. Complaints filed over the years have resulted in inspections by the fire department, and violations were noted by the SCDHS. Violations included spills on open soil, leaking drums, overflowing acid tanks, and drains not noted on original facility plans.

On June 24, 1999, the U.S. Environmental Protection Agency (EPA) received a written request from the New York State Department of Environmental Conservation (NYSDEC), requesting that an emergency response action be conducted at the site. In April 2000, EPA conducted an Integrated Assessment that consisted of the collection of groundwater samples from off-site monitoring wells, two municipal supply wells, and one private well (5 Railroad Avenue). Analytical data from this sampling indicate that 1,2,3-trichloropropane (1,2,3-TCP) is present in the groundwater.

A Preliminary Assessment was conducted in 1983 by EPA, who recommended that ongoing cleanup of the site, with the oversight of the SCDHS, be completed and that the threat to groundwater be defined. In 1991, a Phase II investigation was conducted by the NYSDEC, which included a literature search and on-site soil and groundwater sampling. In 1993, SCDHS conducted groundwater sampling downgradient of the site. A Remedial Investigation/Feasibility Study (RI/FS) was conducted by NYSDEC in 1999. The RI/FS included groundwater sampling, surface soil sampling, and subsurface soil sampling.

The results of sampling conducted in connection with the site indicate the presence of volatile organic compounds, including 1,2,3-TCP, tetrachloroethene, and trichloroethene, in soil and groundwater. Metals and semi-volatile organic compounds, including polycyclic aromatic compounds, have also been detected in soil on site. 1,2,3-TCP concentrations in groundwater ranged up to 7,600 parts per billion at a distance of 600 feet downgradient of the MacKenzie property line. 1,2,3-TCP was detected in the on-site wells sampled by NYSDEC during the Phase II investigation, the off-site wells sampled by SCDHS, and the wells and other groundwater samples collected by NYSDEC during the RI/FS.

According to SCDHS, MacKenzie stored 1,2,3-TCP in three 10,000-gallon tanks on the property. Other historical waste sources include other aboveground storage tanks, leaking drums, waste lagoons, cesspools, and storm water drywells. The lagoons, cesspools, and drywells have been sampled and found to contain contaminants attributable to facility operations, including 1,2,3-TCP at concentrations up to 20,400 micrograms per kilogram.

Institutional Controls:
Media Where IC Applies
(Multiple entries where more than one pathway is impacted)
Restriction Type Instrument
expand Ground Water
Prohibit Ground Water Well Installation/Construction
The Record of Decision (ROD)included existing Suffolk County Department of Health Services (SCDHS)regulations as the necessary institutional controls during the period of restoration of the groundwater to drinking water standards. SCDHS regulations require new residences and businesses to hook up to public water supplies whenever public water mains are reasonably available. Where such mains are not available, the SCDHS regulations require proposed wells for new residences and businesses be tested for water quality prior to use and provide treatment, if necessary. The area around this site has public water mains. At the time USEPA found that site construction was completed, the SCDHS regulations were in place and Suffolk County was expected to adequately enforce its regulations for at least as long as the groundwater was impacted by site-related contamination.

Ground Water
Prohibit Ground Water Well Installation/Construction
New York Environmental Conservation Law Section 15-1527: Permit required for certain wells in Long Island counties. 1. No person or public corporation shall hereafter install or operate any new or additional wells in the counties of Kings, Queens, Nassau or Suffolk to withdraw water from underground sources for any purpose or purposes whatsoever where the installed pumping capacity of any such new well or wells singly or in the aggregate, or the total installed pumping capacity of old and new wells on or for use on one property is in excess of forty-five gallons a minute without a permit pursuant to this title.
