New Jersey Natural Gas (NJNG) Long Branch Plant Site
Update
Long Branch, Monmouth County
September 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. NJNG is expected
to submit a Remedial Action Work Plan (RAWP) to address the subsurface
soils in November 2005. If ground water impacts are found, they will
be addressed as part of the site-wide ground water remedial action.
Soil Gas Investigation
In August 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
issued a letter conditionally approving the RIWP on September 20, 2005.
NJNG will submit a Remedial Investigation Report (RIR) summarizing its
findings in early 2006.
Ground Water Investigation
On September 23, 2005 NJDEP conditionally approved NJNG’s Remedial
Investigation Work Plan/Ground Water Pilot Test Work Plan, which contained
proposals to delineate the dense non-aqueous phase liquid (DNAPL) and
conduct ground water treatment studies. NJNG will implement the additional
studies and present the findings in a RIR. NJNG will submit a combined
RIR/RAWP for ground water on or before March 6, 2006.
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 an 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 an 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. These areas were re-graded and re-seeded in late August/early
September. NJNG submitted the Remedial Action Report (RAR) for the portion
of Block 400, Lot 7 that was subject to unrestricted use remedial action
in September 2005 and NJDEP is reviewing it. 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.
