NYSDEC Certifies Cleanup Requirements Achieved at State Superfund Site

The New York State Department of Environmental Conservation (NYSDEC) has determined that the cleanup requirements to address contamination related to the Metal Etching Co., Inc. site ("site") located at 435 South Main Street, Freeport, Nassau County under New York's State Superfund Program have been or will be met. NYSDEC has approved a Final Engineering Report regarding the site. A copy of the report is available below and at the location(s) identified below under "Where to Find Information." The cleanup activities were performed by the NYSDEC.


Completion of Project

Following site cleanup, NYSDEC reclassified the site in April 2014 from Class 2 (significant threat to public health or environment - action required) to Class 4 (site properly closed - requires continued management) for the following reason(s):

Since remaining contaminated soil exists beneath the site, Engineering Controls (ECs) and Institutional Controls (ICs) are required to protect human health and the environment. An EC/IC Plan has been prepared that describes the procedures for the implementation and management of all EC/ICs at the site. The EC/IC Plan is one component of the Site Management Plan (SMP), and is subject to revision by NYSDEC..

The following is a summary of the remedial actions performed at the site:

  • Excavation of 2,684 yd3 of soil/fill exceeding soil cleanup objectives (SCOs) within identified excavation limits, to low-tide groundwater elevation, approximately five feet below ground surface(bgs);
  • Construction and maintenance of a soil cover system consisting of a geotextile demarcation layer covered by asphalt or permeable pavement to prevent human exposure to contaminated soil/fill remaining at the site;
  • Execution and recording of an Environmental Notice (EN)to restrict land use to commercial use, and prevent future exposure to any contamination remaining at the site;
  • Removal of approximately two yd3 of sediment from the onsite storm water system and disposal at an approved offsite facility;
  • Closure and removal of four underground storage tanks (USTs) onsite in accordance with NYSDEC regulations;
  • Limited removal of approximately 183 yd3 of sediment from delineated area within Freeport Creek and disposal at an approved offsite facility; and
  • Development and implementation of a Site Management Plan for long-term management of remaining contamination as required by the EN, which includes plans for: (1) ICs/ECs, (2) monitoring, (3) operation and maintenance, and (4) reporting.

Remedial activities were completed at the site in Spring 2012. The project is now under long-term site management.

Final Engineering Report Approved

The NYSDEC has approved the Final Engineering Report, which:

  1. Describes the cleanup activities completed.
  2. Certifies that cleanup requirements have been or will be achieved for the site.
  3. Describes any institutional/engineering controls to be used.
  4. Certifies that a site management plan for any engineering controls used at the site has been approved by NYSDEC.

Institutional and Engineering Controls

Institutional controls and engineering controls generally are designed to reduce or eliminate exposure to contaminants of concern. An institutional control is a non-physical restriction on use of the site, such as a deed restriction, when contamination left over after the cleanup action makes the site suitable for some, but not all uses. An engineering control is a physical barrier or method to manage contamination such as a cap or vapor barrier.

The following institutional controls have been put in place on the site:

  • Environmental Notice

The following engineering controls have been put in place on the site:

  • Vapor Mitigation
  • Cover System
  • Fencing/Access Control


Location: The Metal Etching site (site) is located in Nassau County at 435 South Main Street, Freeport, New York, adjacent to the Freeport Creek. The site is bounded to the north by Ray Street, to the west by South Main Street, and the south by Freeport Creek.

Site Features: The site is approximately 1.05 acres. Two buildings, a 2,400 sq. ft. maintenance building and a 1,200 sq. ft. office building, occupy the site. In addition to these buildings, a large two story boat storage rack is located along the southern border of the site area.

Current Zoning/Use(s): The site is currently used as a boat dealership, marina, and boat storage yard. The site is zoned Marine Industrial with the area north of the property zoned for manufacturing.

Historical Use(s): The site has been used for commercial purposes since sometime prior to 1966. The exact date is unknown. Flores Manufacturing, a producer of handbags, operated at the site until 1966. Flores Manufacturing's handbag production process included decorative plating using nickel, chrome, and cadmium. From 1966 to 1999, Metal Etching Corporation manufactured metal nameplates, instrument panels, rulers, and miscellaneous plated products at the site. The process included anodizing, chromate conversion, and chrome-nickel plating. From 1973 to 1982, Metal Etching Corporation operated under the name of Plastic Associates. From 1982 until 1999, the company operated under the Metal Etching Corporation. All operations at the facilities were terminated by 1999. Most site buildings were demolished by 2001.

Site Geology and Hydrogeology: The site is underlain by glacial outwash deposits that generally consist of varying amounts of sand, silt, and clay. The upper three to four feet of material on the eastern portion of the site area is made up of a densely compacted fill material consisting mainly of gravel and debris (such as brick and wood timbers). Below the fill material is a highly organic humus horizon composed of plant organics and shells. This horizon occurs between four and 11 feet below ground surface (bgs). Well-sorted sands and silts are present below this horizon to approximately 30 feet bgs. Between 30 and 35 feet bgs, clay was encountered. The total depth of the clay was not determined. However, the United States Geological Service (USGS) records indicate that this clay layer is approximately 20 feet in thickness.

Groundwater within the site, which is encountered between three to five feet bgs, is tidally influenced with radial flow towards Freeport Creek. Due the study area's proximity to Freeport Creek, the shallow groundwater encountered at the study area is saline and therefore unsuitable for drinking. The nearest public supply well is located approximately 6,000 feet north (upgradient) of the study area, and thus is not impacted by the study area's contamination.
