SUMMARY OF SAMPLING EFFORT On Friday, August 26, 2005, at approximately 10:00 am, NJDEP’s Water Monitoring and Standards’ Bureau of Freshwater and Biological Monitoring (BFBM) was notified of an ongoing spill of fly ash into the Delaware River from a 40 acre storage lagoon located at the PPL Corporation’s Martin’s Creek facility in Pennsylvania. Fly ash is a by-product of coal combustion and can contain heavy metals and arsenic. The spill had apparently begun on Tuesday, August 23, 2005, but notification had not yet been provided to the NJDEP at that time. The discharge was estimated to be flowing at an initial rate of about 27-MGD, and was continuing to spill at the time the Department was notified. The Bureau was contacted by the NJDEP’s Division of Water Supply and requested to provide sampling support services. Over the next several hours, the agency explored potential monitoring strategies, established the monitoring objectives, determined the suite of parameters to be analyzed, prepared sampling equipment / supplies, obtained sample bottles, and verified the availability of staff and logistical resources within NJDEP to respond. It was determined that BFBM was best situated to expeditiously mobilize experienced and equipped ambient monitoring crews to the Delaware River to evaluate the immediate impacts of the spill. Likewise, it was determined that the most timely source of analytical lab support was the NJ Department of Health and Senior Services – ECL laboratory. Once BFBM was authorized to respond, staff assembled GIS maps of the spill area and areas on the Delaware River downstream of the spill site. Of immediate concern to the Bureau of Safe Drinking Water were the potable water intakes of several New Jersey potable water purveyors located downstream of the spill site. In addition to concerns over impacts to drinking water supplies, staff from the Department’s Office of Natural Resource Restoration were concerned about potential impacts on in-stream biota. Both of these concerns were incorporated into the location of sampling points, the selection of media to be sampled (water column and instream sediments), and the final list of sampling parameters (See Attachment A). Both water and sediment samples, where appropriate, were collected. Twelve (12) monitoring sites were initially selected. Ten (10) were on the Delaware mainstem and two (2) were located on the D&R Canal (See Attachments B and C). The linear extent of the Delaware River to be sampled was approximately 77 miles - from the Martin’s Creek spill site in Pennsylvania, to the NJ American Water Company intake in Delran, Burlington County, New Jersey. It was decided, based upon the estimated spill time-of-travel, and the projected direction of the spill, that two (2) days of sampling should be conducted, with a third day possible if the spill was not stopped by the second day (Saturday, 8/27/05). Three sampling crews were dispatched from BFBM’s Ewing Township office late on Friday, 8/26/05. Because of safety concerns and because the tidal cycle on the Delaware River had already shifted to an incoming tide, only certain stations could be sampled on Friday evening. In addition, access to the PPL Martin’s Creek facility boat ramp was denied by the company, so the first station on the Delaware River, DR1, could not be sampled. As a result only eight of the twelve sites were sampled Friday evening. On Saturday, August 27, 2005, the three Bureau sampling teams continued their sampling efforts, delivering the final set of samples to the NJ Department of Health and Senior Services lab on Scotch Road at approximately 8:00pm. Unfortunately, inclement weather prevented the sampling crew from collecting samples at the most downstream two stations (DR9 & DR10). In the end, a total of nine (9) stations were sampled, with those on the mainstem of the Delaware River extending over a 52 mile length of the river.

SAMPLING Design A total of twelve sampling stations were identified for monitoring in response to the fly ash spill (see detailed listing of stations in Attachment B, and the map of stations in Attachment C). Water column and sediment samples were to be collected at six of the most upstream stations in order to assess the impacts of the contaminant plume on in-stream biota. These six stations were to be placed on the mainstem Delaware River beginning from the discharge point at PPL Corporation’s Martin’s Creek plant and ending at the existing Ambient Surface Water Network station at Lumberville (USGS station 01461000). Stations were to be evenly spaced between these two points. Water column samples were to be collected for two days. Sediment samples were to be collected one time. Another six stations were selected to address concerns over potential impacts to NJ potable water intakes. Only water column samples were to be collected at these locations. These stations included four mainstem Delaware River locations and two Delaware and Raritan Canal locations. Water column samples were to be collected at these stations on both Friday, August 26, 2005 and Saturday, August 27, 2005. After consulting with the requesting programs (Division of Water Supply and the Office of Natural Resource Restoration), it was agreed that each of the Delaware River mainstem sampling stations would be sampled at three locations along a transect line: Left (west) Bank, Center and Right (east) Bank (looking upstream). This was done with the understanding that the contaminant plume was flowing mainly on the Pennsylvania side. Delaware and Raritan Canal locations (DRC1 and DRC2) only required a center of flow grab sample. A listing of both the “analyze-immediately” parameters measured in the field, and the parameters analyzed in the lab for both the water column and sediment samples can be found in Attachment A. Implementation Three sampling crews were dispatched from the BFBM’s Ewing Township office at approximately 5:30 pm on Friday, 8/26/05. Because of safety concerns for sampling crews boating on the river after dark, and because the tidal cycle in the lower tidally influenced stations on the Delaware River had already shifted to an incoming tide, it was decided that only certain stations would be sampled on Friday evening. These included those stations not affected by an incoming tide and those that could be sampled from a bridge. In addition, access to the PPL Martin’s Creek facility boat ramp was denied by the company, so the first station on the Delaware River, DR1, could not be sampled. As a result, only eight of the twelve sites were sampled on Friday 8/26/05. The following day, Saturday, August 27, 2005, the teams continued their sampling efforts, delivering the final set of samples to the Department of Health and Senior Services lab on Scotch Road at approximately 8:00 pm. Unfortunately, inclement weather prevented the sampling crew from collecting samples at the most downstream two stations (DR9 & DR10). In the end, a total of nine (9) stations were sampled, with those on the mainstem of the Delaware River extending over a 52 mile length of the river. Of those nine (9) stations, four (4) were sampled for sediment quality (DR2, DR3, DR4, & DR5) as well as water column quality.

RESULTS AND DISCUSSION Results of the water monitoring are provided in Attachment D. These results reflect water column information only. Sediment results will be provided in an addendum to this report when they are available. The analytical results were compared to the applicable Surface Water Quality Standards (SWQS) for each of the parameters measured. The only parameter which exceeded applicable water quality criteria, consistent with the spill as a source, was arsenic. The applicable arsenic criterion for acute aquatic life is currently 360 ug/L [USEPA National Toxics Rule (NTR) Criterion], and for aquatic life protection under chronic exposure, the standard is 170 ug/L (USEPA NTR Criteria). There were no exceedances of the arsenic aquatic life criteria. The arsenic criterion for human health protection is 0.017 ppb. It should be noted that the human health criterion for arsenic is based on a 70-year exposure, which requires an evaluation against a long-term average. An exceedance of the numeric criterion on any given day may not be sufficient to significantly affect the long-term average. As shown in Table 2, the human health criterion for arsenic was exceeded under the spill conditions, with levels up to 30 ppb on Day 1. This criterion has also been exceeded in this section of the Delaware River under non-spill conditions, but to a much lesser extent (1.0-1.5 ppb). Under the spill conditions on Day 1, the arsenic concentrations decreased in the river with distance from the spill location (from 30 ppb at DR3 to 1.6 ppb at DR8). A summary of the water column arsenic concentrations observed in the spill response monitoring is provided in Table 2 below. Table 1, below, provides a summary of historical ambient water column concentrations of arsenic in the Delaware River. Also of note, with the exception of butyl benzyl phthalate (which was found at levels of 19 ppb to 24 ppb which are below the available SWQS of 239 ppb), all of the results for the base neutral/acid extractable analyses have been non-detectable. The parameters analyzed using EPA Method 625 are listed in Attachment A. Continuous water quality data monitors operated by the USGS at Pt. Pleasant, PA and Trenton, NJ logged large spikes in specific conductance on Friday, August 26, 2005 (prior to a rainfall event on Saturday, August 27, 2005). Specific conductance is an indirect measure of the presence of dissolved solids such as chloride, nitrate, sulfate, phosphate, sodium, magnesium, calcium, and iron, and can be used as an indicator of some types of water pollution. It would, therefore, appear that the first impacts of the spill upon water quality in the Delaware River at Trenton, NJ occurred on Friday, August 26, 2005, which was the first day of sampling discussed in this report.

In addition to the monitoring efforts of NJDEP, PPL Corporation has hired a private contractor (Normandeau Associates) to determine biological impacts from the spill and to evaluate potential future problems. The Academy of Natural Sciences in Philadelphia has been hired by PPL Corporation to provide an independent review of environmental assessment and cleanup and to make those findings public.

SAMPLING STATIONS DR1: Delaware River at boat ramp, just downstream from PP& L plant and spill area. The ramp was to be accessed from Route 611 in Pennsylvania. DR2: Delaware River at boat ramp, approximately 5.2 miles above Easton Bridge. The ramp was to be accessed from Route 611 in Pennsylvania. DR3: Delaware River at free bridge (North Hampton Street) in Easton. (USGS station 01447000) DR4: Delaware River at Riegelsville (USGS station 01457500) DR5: Delaware River at Frenchtown (USGS station 01458500) DR6: Delaware River at Lumberville (USGS station 01461000) DR7: Delaware River at Lambertville (USGS station 01462000). DR8: Delaware River at Trenton (USGS station 01463500) DR9: Delaware River at Burlington City, just above intake between city and Burlington Island. DR10: Delaware River just above intake at Delran and below Rancocas Creek. DRC1: Delaware and Raritan Canal at Lumberville. DRC2: Delaware and Raritan Canal on Weston Canal Road in Franklin Township(Above Intake).
Notes: DR1 could not be sampled. Staff members were denied access to boat ramp by PP&L due to safety concerns. Apparently fly ash and mud had covered the boat ramp. DR9 and DR10 could not be sampled due to inclement weather and an incoming tide. Sample design required these locations to be sampled either on an outgoing or slack tide. Sediment at DR2 was composited due to the lack of depositional material. Sediment at DR6 could not be collected due to the lack of depositional material. Sediment at DR5 could only be collected on the right bank, due to the lack of depositional material.
