Case: Mattiace
Petrochemical, NY
 |
Site History: Chronic release of hazardous substances began in
the mid-1960s.
Location: The Mattiace Petrochemicals Company Site is located
in Glen Cove, New York. The Natural Resource Damage (NRD) assessment area
includes Glen Cove Creek.
Trustees:
Case status: Restoration Planning.
Overview: The Mattiace Petrochemical Company Site is an
inactive chemical distribution facility located on Long Island on Garvies Point
Road, north of Glen Cove Creek. Garvies Point Preserve, which fronts Hempstead
Harbor, is located west of the site along Garvies Point Road. From the
mid-1960s until 1987, Mattiace received chemicals by tank truck and
redistributed them to its customers. The company also operated the M&M Drum
Cleaning Company on the Site until 1982. The primary migration pathways from
the Site to habitats of concern in Glen Cove Creek were direct discharge
through underground pipes, groundwater discharge, and surface water transport.
When the facility was in operation, overflowing chemicals and stormwater were
transported to a solvent/stormwater separator and ultimately discharged to the
creek. Runoff eroded soil and created gullies in the driveway that served to
direct flow towards Garvies Point Road. Garvies Point Road is connected to Glen
Cove Creek via a storm sewer and underground pipe. Contaminated groundwater may
have contributed to surface water contamination. Additionally, large leaching
pools were constructed on-site to collect surface water runoff and to leach
solvents into the ground. Elevated concentrations of polynuclear aromatic
hydrocarbons (PAHs), pesticides, and metals were identified in the sediment of
Glen Cove Creek. About 38 acres of tidal habitat have been degraded due to
release of site-related contaminants, reducing the quality of habitat available
for fish and wildlife.
The site was added to the National Priorities List in 1989 and a record of
decision (ROD) was signed in June 1991 selecting in situ vapor extraction of
soil, limited excavation of soil contaminated with pesticides, removal of all
above and below ground tanks and cisterns, and groundwater pumping and
treatment.
