PRESENTATIONS/STAFF REPORTS
DEP Enforcement, Exit 77
Area Businesses. Ms. Kimberly Morewood, Local
Government Liaison with the Southcentral Region of the DEP, introduced members
of the DEP making presentations tonight: Greg Bowman, Underground Storage Tank
Manager; Bill Noll, DEP Project Manager; and Janice Vollero, Field
Representative from the Water Quality Division.
Bill Noll, Travel Centers of
America Project Manager. Mr. Noll gave a detailed
overview of activities at TA. There are
a total of 39 monitoring wells on the site with 22 showing free product
manifestations. 10,604 gallons of
product have been removed. The amount
of product removed has been sharply declining.
In the last 6 months 521 gallons has been recovered compared with 4,943
gallons in the previous 6 months. The
total remedial action territory is approximately 4.5 acres. Integrated Science and Technology from York
is the firm working on behalf of the DEP.
The remedial action plan, submitted and approved in October, 2002, calls
for 14 recovery wells, 12 of which are already in place. The long-term remediation plan calls for
free product pumping and total fluids pumping combined with vacuum-enhanced
recovery. Mr. Noll utilized overhead
slides to illustrate the overall site, the proposed test well configuration,
the plume configuration of the monitoring wells, and the zone of effectiveness
or area of influence of the pilot tests last June and July. He also showed a cross section, which
illustrated how product can get trapped with the fluctuation of groundwater
levels. Due to the fluctuations in
these groundwater levels the product recovery time may take several years to go
through several groundwater level cycles in order to capture trapped product.
There was some discussion of
residual product from past site use.
The anticipated start date of the recovery system is between July 11 and
August 11, 2003. Approximately 1 to 1
1/2 million gallons flow through TA each month. The surface spills on the parking lot are a small percentage of
the total volume. There have been two
different fingerprinting analysis completed on the soil with two different
results. The DEP is confident the
source of contamination is gone. The
current fuel tanks are not double-walled, they are generally single walled
fiberglass or single-walled steel tanks with cathotic protection. Current leak detection systems include
automatic tank gauges and an excavation liner.
There was discussion about
the storage of recovered product. This will
be stored on site, not in 55-gallon drums but in storage tank entities. The complete removal from these tanks will
be done either on a volume basis or on a time schedule.
Janice Vollero, Field Rep,
Water Quality Division. Ms. Vollero discussed activities
at the Pilot Travel Center. Her
position is a job-sharing one with the another individual, Laurie Mitzel. Pilot does not have an NPDES permit, only a
general permit for ground water remediation.
The main problem at the Pilot site is with the sedimentation pond. Upon an inspection of the site on September
24, 2002, Ms. Vollero noticed product in the sed pond. Since that time there have been 10
inspections of the site with 5 incidents of oil in the pond and violations
issued. Pilot is currently vacuuming
the pond. The last meeting with Pilot
was on February 14 to address the issue of where the oil appearing in the sed
pond is originating. Ms. Vollero’s main
emphasis is to prevent oil from getting to the sed pond and also control the
water in the pond. The oil/water
separator appears to be functioning appropriately. Pilot has been asked to monitor the sed pond on a daily basis and
notify DEP by phone of any problem. An
incident occurred Friday night, the telephone report was made, and Pilot had a
vacuum truck in Saturday morning to take care of the spill. Apparently the incident Friday night was not
reported to the Township. Ms. Vollero
reviewed a site map of the Pilot site including the storm drains and oil/water
separator. Pilot believes a big portion
of the problem is specific dumps into the storm drains. They will be installing signs at the drains
notifying of the PA Clean Streams law and the penalties of violation.
There was a
great deal of discussion regarding the current configuration of the piping in
the sedimentation pond. Jason McCain,
Environmental Manager for Pilot Travel Centers, reviewed the preliminary plans
for a concrete siphon dam, which is a pond within a pond to act as a further method
to retain the fuels before it gets to the soils. Mr. McCain said as soon as the plans are finalized, hopefully by
mid April, he will make sure a copy of the drawings are given to the Township
for review by the Township Engineer.
Ms. Vollero
finalized the discussion by outlining the current testing and reporting
requirements. She said she would send
the Township copies of written reports of the inspections. The oil/water separator is checked for fuel
once a week with written reports once a month.
There was a brief discussion of the conditions at Gables. There are a number of monitoring wells showing marginal levels of groundwater contamination. There is no active remedial action currently taking place.
Discuss DCED Program. Mr. Rimer contacted Dean Fernsler to arrange a program on April
3, 2003.
