Re: 2016-2017 Annual License Renewal Application – Handling and Storage of Toxic or
Hazardous Materials (Revised)
Dear Mr. Lawson:
On behalf of NSTAR Electric Company d/b/a Eversource Energy (Eversource), I am submitting this
2016-2017 Annual License Renewal Application for the Handling and Storage of Toxic or Hazardous
Materials for the operation and maintenance of our vehicle wash system at 484 Willow Street,
Yarmouth, MA.
The following information is submitted per the provisions of the license:
Water Usage: 6,250 gallons of town water were used by the vehicle wash system between June
1, 2015 and June 1, 2016. Water from the vehicle wash system is typically removed for
disposal twice a year. The vehicle wash system has its own meter (Recordall Model 15 Badger
Meter, serial number 80463728).
System Pumping & Disposal: From June 16, 2015 through June 15, 2016, a total of 1,120
gallons of water and oil were pumped from the oil water separator during this period and were
shipped to Clean Harbors Environmental Services facility in Braintree, Massachusetts.
Leaks/Reportable Spills: No reportable spills of oil or hazardous materials to the floor drains
occurred in the garage or anywhere else on the service center property during the period of June
1, 2015 thru June 1, 2016. For the annual period ending June 1, 2016, the oil/water separator
was cleaned by Clean Harbors on January 20, 2016, prior to lining the tank piping system. The
oil/water separator was cleaned by Clean Harbors on May 24, 2016 prior to the tank piping
tightness testing. Due to the tightness failure of the May 24, 2016 event, Clean Harbors
returned to the facility on the date of the next evaluation (June 14, 2016) to clean the oil/water
separator. Copies of the associated manifests completed by Clean Harbors are included in
Attachment A.
Waste Generation & Disposal: All hazardous waste, including used motor oil, oily solids and
used mineral oil dielectric fluid as well as spent oil filters and anti-freeze generated at the site
were transported off-site and properly disposed per applicable federal and state regulations.
247 Station Drive, SE270
Westwood, Massachusetts 02090
Copies of manifests from June 1, 2015 through June 1, 2016 are included as Attachment B.
Copies of manifests are also maintained on file via an online database.
Pipe Lining: On January 21, 2016, New England Pipe Restoration, Inc. (NEPR) of Leominster,
Massachusetts, applied a resin lining to the interior walls of the garage drainage pipes. NERP
used a cured in place pipe repair technology, which allows lining of the drainage pipes without
excavation or cutting into the existing pipes. The Perma-Laterial liner material has a reinforced
scrim to eliminate stretching during the inversion process. The reinforcement scrim allows the
liner to invert smoothly through existing piping while preventing the liner from stretching.
Additionally, Chet’s Plumbing of Marion, Massachusetts, replaced the floor drain fittings and
connections during the January 2016 event.
One confirmatory soil sample was collected for laboratory analysis from under the leaking pipe
joint. The sample was submitted under chain of custody to GeoLabs, Inc. of Braintree,
Massachusetts and was analyzed for extractable petroleum hydrocarbons (EPH) via the
Massachusetts Department of Environmental Protection method. Analytical results were all
below the laboratory detection limit for EPH constituents. A copy of the laboratory report is
included as Attachment C.
Piping Repairs: Due to the failed tightness test on May 24, 2016, NEPR returned to the site to
reline the garage drainage pipes and floor drain connections. NERP used the same Perma-
Laterial liner material to line reline all existing garage drainage piping.
Tank Monitoring Testing & Certification: The Veeder-Root monitoring system is programmed
to continuously detect leaks in the industrial wastewater holding tanks. Overall, the system has
functioned without mechanical error. On June 14, 2016, Joseph A. McKnight, a certified
Veeder-Root system technician from Tighe & Bond (T&B), certified that the tank monitoring
system was operating correctly and compliant with manufacturer’s specifications. Vedeer-Root
testing records for the previous permit year are included in Attachment D.
Piping Tightness Testing & Certification: On June 14, 2016, a piping tightness test was
performed on the system in accordance with the Massachusetts State Plumbing Code. The test
was performed under the supervision of David Horowitz, a Massachusetts licensed Professional
Engineer (PE) with T&B. The results of the test indicate that the piping system is “tight.” A
copy of the PE opinion letter is included as Attachment E.
