New Jersey Natural Gas (NJNG) Long Branch Plant Site
Update
Long Branch, Monmouth County
August 2005
(For historical information about activities
that NJDEP and NJNG have conducted at these areas, please refer to the
monthly updates NJDEP has provided
to CCC since January 2005.)
This report is provided in response to a request by the Concerned Citizens
Coalition of Long Branch (CCC) for monthly updates on work conducted and
planned at four areas associated with the former Long Branch Manufactured
Gas Plant (MGP). These areas are:
- the former MGP (including the former Conrail properties, the eastern
off-site property, and the former Jerry Morgan Park)
- the off-site portion of Troutmans Creek that flows north of the MGP
- residential areas where the community has expressed concern about
potential soil contamination (Long Branch Avenue, Seaview Avenue, Grant
Court and Ellis Avenue)
- the former Seaview Manor housing complex
All work is consistent with NJDEP’s Technical Requirements for
Site Remediation, which were developed to ensure remedial actions protect
human health and the environment.
- Long Branch Plant
Red Brick Building
NJNG recently proposed additional investigation to delineate the extent
of trichloroethene (TCE) and perchloroethylene (PCE) contamination in
the soil beneath the concrete pad where the red brick building was located,
as well as ground water sampling to evaluate potential ground water
impacts. NJDEP conditionally approved the additional work in July, and
NJNG plans to conduct the sampling in October 2005. Following the completion
of the soil and ground water investigation, NJNG will submit a Remedial
Action Work Plan (RAWP) to address the subsurface soils. If ground water
impacts are found, they will be addressed as part of the site-wide ground
water remedial action.
Soil Gas Investigation
On August 15, 2005 NJNG submitted a Sub-Slab Sampling Remedial Investigation
Work Plan (RIWP), which detailed proposals to investigate potential
vapor intrusion at the Talco and Atlantic Plumbing buildings. NJDEP
is reviewing this document and expects to issue comments in October
2005.
Ground Water Investigation
On August 15, 2005 NJNG submitted a Remedial Investigation Work Plan/Ground
Water Pilot Test Work Plan, which contains proposals to delineate the
dense non-aqueous phase liquid (DNAPL) and conduct ground water treatment
studies. After NJDEP approves the document, NJNG will implement the
additional studies and present the findings in a Remedial Investigation
Report (RIR). NJDEP recommended that NJNG submit a combined RIR/RAWP
for ground water on or before January 31, 2006. NJNG agreed to submit
the combined RIR/RAWP, but requested a due date of March 6, 2006. NJDEP
has granted this request based on the amount of work required to complete
the investigation and prepare the documents.
On-Site Portion of Troutmans Creek
Remediation of the southern on-site portion of the Troutmans Creek is
still pending, as this work cannot be implemented until NJNG obtains
access from the owner of Atlantic Plumbing Supply Company (APSC) property.
NJNG submitted an unrestricted use RAWP in February 2005 and NJDEP issued
a conditional approval letter on April 2005. The unrestricted use remedial
action will be implemented once NJNG obtains access to the property.
NJNG has begun litigation to gain access.
- Troutmans Creek
On August 8, 2005 NJNG submitted a RIR summarizing the results of the
creek sampling it conducted since March 2004. NJDEP is reviewing the
report and expects to issue comments in November 2005.
- Off-Site Residential Areas
NJDEP collected soil samples from the right-of-ways along Long Branch
Avenue, Seaview Avenue and Ellis Avenue and from Grant Court in May
2005. These samples were analyzed for volatile organic compounds, semi-volatile
organic compounds, total petroleum hydrocarbons and metals. NJDEP expects
to issue a RIR detailing its findings in the fall of 2005.
- Seaview Manor
NJNG finished removing the contaminated soil from areas where buildings
are to be re-built, and a minimum of two feet of contaminated soil from
the other areas. The backfilled areas were re- graded and re-seeded
in late August/early September. NJNG will submit the Remedial Action
Report (RAR) for the portion of Block 400, Lot 7 that was subject to
unrestricted use remedial action in September 2005. The RAR for the
remainder of the parcels will be submitted in January 2006, with the
exception of the culvert (see below).
Culvert Status
NJNG will remove the culvert that connects the on-site portion
of Troutmans Creek to the off-site portion of Troutmans Creek north
of Seaview Avenue and the underlying contamination during remediation
of the sediments in the off-site portion of Troutmans Creek. NJNG and
NJDEP expect this work will occur in the spring and summer of 2006.
