New Jersey Natural Gas (NJNG) Long Branch Plant Site
Update
Long Branch, Monmouth County
January 2005
The following summarizes work recently conducted and planned at four
areas of the site: the former MGP, including several related properties;
the off-site portion of Troutmans Creek that flows north of the MGP; confirmatory
soil sampling on Long Branch Avenue, Seaview Avenue and Grant Court; and
the remedial action for the Seaview Manor housing complex.
- Long Branch Plant
The Long Branch Plant portion of the site consists of the former manufactured
gas plant (MGP) site and several related properties: the former Conrail
properties, the eastern off-site property, and the former Jerry Morgan
Park. NJNG has removed soil that was contaminated with polycyclic aromatic
hydrocarbons (PAHs) from these portions of the site and restored the
properties. In addition, NJNG removed contaminated sediments from the
majority of the on-site portion of Troutmans Creek and stabilized the
streambed. Additional remediation of the southern, on-site portion of
the creek is required, but cannot be implemented until NJNG finishes
negotiating access with the affected property owner.
NJNG is also evaluating remedies to address ground water at the site,
which is contaminated with coal tar product and related compounds such
as benzene and PAHs. NJDEP expects NJNG to submit a Remedial Action
Work Plan in 2005 outlining its proposals to remediate the ground water.
- Troutmans Creek
In mid-November, NJNG collected surface water and sediment samples from
the creek between Seaview Avenue and a distance halfway between Joline
Avenue and Atlantic Avenue for analysis of PAHs, alkylated PAHs, total
petroleum hydrocarbons (TPH), metals and additional general chemistry
and physical testing. NJNG collected deep sediment samples from Troutmans
Creek between Seaview Avenue and Joline Avenue from January 10-17, 2005.
More deep sediment samples will be collected between Joline Avenue and
Atlantic Avenue once the ice thaws in the creek. Soil sampling along
the creek banks is also planned. NJNG is currently scheduled to submit
a report with the results of the sampling on May 20, 2005.
NJDEP collected surface water and sediment samples from the creek between
Joline Avenue and Atlantic Avenue in December 2004. These samples are
being analyzed for PAHs, TPH, metals and other parameters. NJDEP expects
to issue a preliminary report on its findings in March or April of 2005.
- Confirmatory Sampling on Long Branch Avenue and Grant Court
Under NJDEP’s oversight, NJNG has delineated contaminated soil
at the Long Branch Plant MGP site and implemented a remedial action
in accordance with state cleanup regulations. (See item #1.) However,
in response to concerns regarding potential soil contamination beyond
the limits of the approved remedy, NJDEP plans to collect soil samples
along Long Branch Avenue, Grant Court and Seaview Avenue. The sampling
will occur in February or March 2005.
- Seaview Manor
Sampling conducted by NJNG has confirmed there is contaminated soil
under the Seaview Manor housing development. All of the contaminated
soil will be removed from areas where the buildings are to be re-built,
and a minimum of two feet of contaminated soil will be removed from
the other areas. Demolition of the Seaview Manor buildings was completed
in November 2004 and the soil removal began on December 3, 2004. The
schedule calls for substantial completion of remediation activities
(not including rebuilding) by September 2004 and submission of a Remedial
Action Report in January 2006.
