1 SUMMARY OF CONSTITUENTS OF POTENTIAL CONCERN (COPCs) TRANSPORT PATHWAYS TO THE CREEK The current understanding of the transport mechanisms of COPCs from the upland portions of the Consolidated Edison, Inc. (Con Edison) – 11th Street Conduit site (site) to Newtown Creek is summarized in this section and in Table 1 and supported in the following sections.

Overland Transport The site is adjacent to Newtown Creek. Stormwater at the site is expected to infiltrate into the ground, flow overland towards Newtown Creek, or discharge to the creek via a local stormdrain system. There is insufficient evidence to make a current or historical pathway determination.

Bank Erosion No specific evidence of bank erosion was identified in the available site records. A wooden bulkhead extends across the shoreline at the site. There is insufficient evidence to make a current or historical pathway determination.

Groundwater Information regarding on-site groundwater investigations was not identified in documents available for review. There is insufficient evidence to make a current or historical pathway determination.

Overwater Activities The site is adjacent to Newtown Creek. Information regarding overwater activities was not identified in documents available for review. There is insufficient evidence to make a current or historical pathway determination.

Stormwater/Wastewater Systems Operations at the site are covered under New York State Pollutant Discharge Elimination System (SPDES) Permit No. NY0201138 for discharge to one outfall to Newtown Creek (believed to be Outfall NCB-006131-002) located at the northwest corner of the property in Brooklyn (Ash Street and McGuinness Boulevard). The outfall is connected to a sump pump that discharges up to 85,000 gallons per day (gpd) of groundwater and stormwater that infiltrates into and collects in the Con Edison utility conduit beneath Newtown Creek. Direct discharge of stormwater and wastewater is a potentially complete historic pathway and a complete current pathway. There is insufficient evidence to make a current or historical pathway determination for discharge to sewer/combined sewer overflows.

Air Releases Information regarding air emissions from the site was not identified in documents available for review. There is insufficient evidence to make a current or historical pathway determination.

2 PROJECT STATUS The site is currently listed as a Conditionally Exempt Small Quantity Generator (CESQG; FOIA Report 2009; EDR 2010). The Resource Conservation and Recovery Act (RCRA) ID is NYR000078469 and the NYSDEC Site Manager is Bob Wither.

No available documents containing environmental investigations were identified for this site.

4 PROPERTY DESCRIPTION This upland parcel occupies approximately 0.67 acres1 adjacent to Newtown Creek (see Figure 1). The property is located at the intersection of Ash Street and McGuinness Boulevard in Brooklyn, in the county of Kings, New York. The 11th Street Conduit provides an artificial closed conduit under Newtown Creek, which houses the Con Edison electrical distribution cable between Brooklyn and Queens. The tunnel extends from the site at Ash Street and McGuinness Boulevard to 11th Street and 47th Road in Queens (see Attachment 1). The property is generally flat with steep slopes at the bulkhead adjacent to Newtown Creek. The majority of the site appears to be unpaved with areas of vegetation above the creek. Structures include a single, one-story building, approximately 850 square feet, located on the western portion of the property. The building contains the primary “headhouse” that controls tunnel operations at the property. A wooden bulkhead extends across the 150-foot shoreline at the north side of the property.

The site is bordered by Newtown Creek to the north, an industrial properties to the east and south, and by the Pulaski Bridge to the west. The property lies within a manufacturing district, zoned as M1-2 (NYCDCP 2011). M1 districts typically include light industrial uses, such as woodworking shops, repair shops, and wholesale service and storage facilities..

A 2010 aerial photograph of the site is presented as Figure 1.

5 CURRENT SITE USE The site is currently owned by Con Edison and is used for electric power distribution.

6 SITE USE HISTORY The lot was formerly used as a coal yard (E. Belcher Hyde Map Co. Inc. 1929). Consolidated Edison, Inc. purchased the lot in 1964 (Con Edison 1994).

7 CURRENT AND HISTORICAL AREAS OF CONCERN AND COPCS The current understanding of the historical and current potential upland and overwater areas of concern at the site is summarized in Table 1. The following sections provide brief discussion of the potential sources and COPCs at the site requiring additional discussion.

7.1 Uplands Reviewed records did not indicate upland areas of concern. This could be due to missing information or a lack of environmental issues at the site. COPCs at the site include polychlorinated biphenyls (PCBs), petroleum hydrocarbons, creosote, and volatile organic compounds (VOCs) based on general knowledge of constituents associated with electrical distribution equipment, spill reports, and site SPDES permit requirements (Con Edison 1994).

7.2 Overwater Activities Overwater activities are not a current transport pathway.

7.3 Spills Documented spills at the site are summarized as follows:

8 PHYSICAL SITE SETTING Site-specific hydrogeologic information was not identified in documents available for review. The geologic setting for Newtown Creek consists of impermeable Precambrian and Paleozoic crystalline bedrock, overlain by the Upper Cretaceous Raritan formation, Magothy formation and Matawan Group (undifferentiated), unconsolidated Pleistocene deposits and upper Pleistocene glacial deposits and Holocene shore, beach salt-marsh deposits, and alluvium, along with local occurrences of artificial fill (Buxton et al. 1981; Soren and Simmons 1987). The primary areas of groundwater discharge are Newtown Creek and its tributaries and the East River (Misut and Monti 1999). In the vicinity of Newtown Creek, groundwater flow in the Upper Glacial aquifer is generally north and south towards the creek. With increased distance from the creek, groundwater will flow towards the nearest surface water body to discharge (Misut and Monti 1999). Incidences of perched groundwater may occur above the Upper Glacial Aquifer in some areas, particularly in formerly low-lying areas that have been filled. Groundwater flow at a specific property may differ from the regional pattern due to pumping for groundwater treatment or dewatering activities (Misut and Monti 1999), the presence of buried utilities, or other preferential pathways.

Outfalls NCB-246 and NCB-248). Seepage of groundwater through the conduit walls and infiltration of rainwater through the riser shafts located at Ash Street and McGuinnes Boulevard and at 11th Street and 47th Road is discharged to Newtown Creek at Outfall NCB­006131-002 (Con Edision 1994). Sanitary wastewater is conveyed to the Newtown Creek WPCP (NYCDEP 2007).

9.3.2 SPDES Permit The SPDES permit application was submitted on March 20, 1994. The operation contributing to the discharge flow is described as a groundwater infiltration and stormwater pump/recovery system from the tunnel. Because the electrical distribution cables within the conduit are oil-filled, an oil-water separator was installed to separate any oil from collected waters prior to discharge, as depicted in Attachment 2 (Con Edison 1994; USEPA 1994b). The oil-water separator was installed in 1995. Sometime prior to the 2006 permit renewal, a coalesce filter was also installed in front of the oil-water separator to increase filtration capabilities of the outfall prior to discharge to Newtown Creek (NYSDEC 2006). Prior to 1995, collected water was discharged to Newtown Creek via sump pump discharge piping without treatment (Con Edison 1994).

The discharge flow is given as 85,000 gpd. The permit and additional modifications were issued on January 9, 1997, and it was subsequently renewed on a 5-year cycle. The most recent renewal was August 3, 2006 (expiring February 29, 2012). Permit parameters and limitations are summarized as follows (NYSDEC 1997, 2001, and 2006; NYSDEC 2011):

Note: mg/L – milligram per liter

9.3.3 Wastewater Data The SPDES permit application for the site includes analytical results for an unknown number of samples of conduit seepage water collected between December 1993 and February 1994. According to SPDES discharge monitoring data from between April 30, 2006, and March 31, 2011, the site was in compliance for all dates monitored, except for one exceedance for oil and grease levels on November 30, 2006 (documented discharge: 21 mg/L; NYSDEC 2011). No PCB monitoring results were present in the 2006 to 2011 SPDES monitoring data. Discharge monitoring data for the period from issuance of the permit in 1997 to April 2006 was not available.

A summary of the available wastewater sampling results is provided in the following table:

9.3.4 Surface Water Summary The site discharges to Newtown Creek groundwater and stormwater that infiltrates into and collects in the tunnel. An SPDES permit was issued to the site in 1997 and has been renewed on a 5-year cycle. The current permit will expire in 2012 (NYSDEC 2006, 2011). One effluent violation is documented in December 2006 for oil and grease discharge of 40 percent above the specified permit limit (USEPA 2010). However, no other permit violations or compliance issues are documented at the site (USEPA 2010 and 2011).
