Re: Sewer Tie-in
Dear Mr. Coppola:
The Health Department has been supplied with a list of all residences, currently on septic,
which have access to the municipal sewer system. As previously published at a Public
Hearing on March 17, 1994, the Board of Health has adopted regulations concerning the
required sewer tie-in. The following timetable concerning your property status was
adopted:
4.1 All establishments that currently do not have municipal sewer available
to them must connect to the sewer as soon as it becomes available, with a
maximum time limit of six months.
The purpose of these regulations is to safeguard North Andover's drinking water, surface
waters, groundwater and surrounding environment. Sanitary sewer is believed to be the
most effective form of wastewater treatment. A copy of the entire regulation can be
obtained at our office.
Your property is in violation of this Board of Health regulation. Please contact the Health
Department regarding this matter immediately. If we do not hear from you by May 10,
2000 your name will be placed on the regularly scheduled Board of Health meeting agenda
and placed on public notice. The meeting will be held on May 25, 2000 for discussion of
legal action including court hearings.

Any questions concerning this regulation should be directed to the Board of Health at
(978) 688-9540. Additional inquiries regarding the physical tie-in and permitting process
should be directed to the Department of Public Works at (978) 685-0950. Please be
advised this Board intends to persevere in this regulation.

NOTICE OF AUDIT FINDINGS
Dear Mr. Blair:
On August 15, 1994 , the Massachusetts Department of
Environmental Protection (the Department) issued a Notice of Audit
informing you that the Department was conducting an audit of
certain activities related to the above-referenced disposal site
pursuant to 310 CMR 40. 1100. That audit is now complete. The
purpose of this notice is to explain the results of the audit.
The audit included a review of the following:
■ waiver Activities
The audit consisted of the following activities:
■ A review of the documents in Department files.
■ A Notice of Audit (NOA) dated August 15, 1994 .
■ A written Request for Information (RFI) dated August 15,
1994 .
■ A review of the documentation provided by your
environmental consultant, Fugro-McClelland (East) , Inc.
(FME) in response to the Department ' s RFI; including
recent groundwater monitoring data, BTEX influent and
effluent concentrations, and status reports which justify
the termination of the groundwater recovery and treatment
system.

SITE SUMMARY
The Phase I investigation reports that six (6) underground
-storage-- -tanks (USTs) -- containing - gasoline-- -and--- fuel oil---were-- --- -
excavated and removed from the site in April 1985. Approximately
1, 000 cubic yards of petroleum contaminated soil generated by the
tank pull activities remained stockpiled on-site until its disposal
in 1988.
Moderate levels of benzene, toluene, ethylbenzene, and xylenes
(BTEX) were detected in groundwater samples collected from the on-
site monitoring wells. The maximum total BTEX concentration
detected was 7, 600 ug/l in the March 1986 sample taken from
monitoring well OW-2 .
The depth to groundwater ranges from 5 - 7 feet below grade
across the site. Sandy fill was observed to depths of 5 feet below
grade, at which point glacial till was encountered.
The site was granted a Waiver by the Department on December
20, 1989 . A groundwater treatment/vapor recovery system was
subsequently installed and activated in October 1991. The system
consists of a recovery well and trench located on the eastern
portion of the site intersecting the area of the former pump
island. Historically,' elevated levels of BTEX contamination were
detected in this area.
In November 1992 , five air injection points were installed in
conjunction with an air sparging system to further expedite the
clean-up of the site. Two additional groundwater monitoring wells,
OW-11D and OW-12 , were also installed in December 1992 in an effort
to provide further groundwater data pertaining to BTEX
concentrations. Both OW-11 and OW-11D are located downgradient of
the recovery trench; OW-12 lies upgradient of the recovery trench.
AUDIT SUMMARY
The Department was notified on June 27 , 1993 by FME that the
soil venting/groundwater recovery and treatment system had been
deactivated on June 1, 1993 based on " . . .recent and historical
laboratory data which indicated that the system had achieved its
goals of reducing the BTEX concentrations in the groundwater to
levels that do not pose an unacceptable risk to human health,
safety, public welfare, and the environment. " Since the Department
was not in receipt of any post-May 1992 groundwater data to justify
the termination of the system at the site, the NOA/RFI was issued
to the Southland Corporation.
The information requested in the NOA/RFI was tsubmitted to the
f
Notice of Audit Findings
Page 3
Department within the two week Interim Deadline set by the
Department. The groundwater monitoring results from March 1991
through December 1993 indicate that BTEX levels have decreased to
method _detection.-.-limits-- _1 u 1 for- BTEX components)( g/ p ) --in--a1-1----------
groundwater monitoring wells except OW-11, OW-11D, and OW-12 . The
total BTEX concentrations detected in groundwater samples collected
from these wells during the December 1993 sampling round were 1, 429
ug/l, 3 , 300 ug/1, and 223 ug/1, respectively.
The results of a Hydropunch Survey conducted at the site on
July 20, 1994 were also submitted to the Department in response to
the NOA/RFI . The survey involved the installation of five
groundwater sampling points (HP - 1, 2 , 3 , 4 , and 5) along Route
125 beyond the underground water and sewer lines which run parallel
to the eastern property line. Elevated BTEX levels were detected
in HP-3 and HP-4 (total BTEX 2 , 353 ug/l and 13 , 390 ug/l,
respectively) . HP-3 and HP-4 lie hydrologically downgradient of
monitoring wells OW-11 and OW-11D. Due to this fact, the
Department disagrees with FME's statement that monitoring wells OW-
11 and OW-11D simply represent localized "hot spots" at the site.
The system was re-activated at the site on April 21 and May 6,
1994 for the performance of two pump tests on monitoring wells OW-
11 and OW-11D. The purpose of these tests was to meet the National
Pollutant Discharge Elimination System (NPDES) permit requirements
for the site. The results indicated the total BTEX system
influents to be 217 ug/l (with 210 ug/l as benzene) and 74 ug/l
(with 69 ug/l as benzene) , respectively.
AUDIT FINDINGS
No deficiencies or violations were identified during the
audit. On the basis of the information reviewed during the audit,
and in reliance upon the accuracy of that information, the
Department believes that the current groundwater recovery and
treatment system would not be effective in further reduction of the
on-site contaminant concentrations.
ADDITIONAL COMMENTS
The following section contains the Department ' s observations
and recommendations pertaining to the current site conditions.
These observations and recommendations do not constitute
deficiencies or violations. Instead, they represent shortcomings
in meeting general performance standards under Chapter 21E and the
Massachusetts Contingency Plan (MCP) and are included to assist you
and your environmental consultant in completing the Phase II

investigation and determining the appropriate response actions to
address the remaining on-site contamination.
The historical groundwater data submitted to the Department
indicates that the groundwater recovery and treatment system has
been relatively ineffective in lowering BTEX levels in the area
downgradient of the recovery trench. Consequently, the Department
has identified the following concerns which should be evaluated and
addressed in accordance with 310 CMR 40. 000 and/or 310 CMR 40. 0000
during the Phase II site investigation and prior to submitting a
Remedial Response Completion Statement or Response Action Outcome
(RAO) for the site:
Elevated BTEX concentrations still remain in recent
groundwater samples collected from downgradient monitoring wells
OW-11 and OW-11D; and from Hydropunch monitoring points HP-3 and
HP-4 . Additionally, the GW-2 standard for xylenes (6, 000 ug/1) was
exceeded at HP-4 (7 , 970 ug/1) . This indicates that the gasoline
plume has migrated beyond the recovery trench toward Route 125.
This situation poses a potential vapor threat to the
residences located on the opposite side of Route 125, as well as to
the underground water and sewer lines which lie beneath Route 125.
Therefore, the .Department disagrees with FME' s June 27th conclusion
that an unacceptable risk to human health, safety, public welfare,
or the environment no longer exists at the site.
Pursuant to 310 CMR 40. 545 (g) , (h) , and (i) , a demonstration
of No Significant Risk is required relative to the potentials for
volatilization of BTEX vapors into the residences, and infiltration
to the underground utility lines. Accordingly, the extent of the
gasoline plume must be defined in order to fully characterize the
potential risks at the site. Additional investigations may
include, but are not limited to, the proposed installation of
additional Hydropunch groundwater monitoring points as noted in the
August 26, 1994 FME response to the Department ' s NOA/RFI.
If the investigations and response actions conducted at the
site cannot reach a condition of No Significant Risk prior to the
expiration of the Waiver on December 20, 1994 , then the site must
be evaluated and addressed pursuant to the revised Massachusetts
Contingency Plan 310 CMR 40. 0000, effective October 1, 1993 .
CONCLUSION
These findings do not apply to response actions or other
aspects of the site that were not reviewed in the audit. The audit
focused primarily on compliance with certain requirements of M.G.L.
c. 21E and the MCP and, to a limited extent, on other applicable

requirements. This audit does not preclude future audits of past,
current, or future response actions or activities at the site or
inspections to confirm compliance with applicable requirements of
other laws or regulations enforced by the Department.
These findings do not 'in any way constitute a release from
liability under M.G.L. c. 21E, the MCP, or any other law,
regulation, or requirement. No portion of this Notice shall be
construed to relieve any person from an obligation for Response
j Action Costs or damages related to a site or disposal site for
which that person is liable under M.G.L. c. 21E or from any
obligation for any administrative, civil or criminal penalty, fine,
settlement, or other damages. No portion of this Notice shall be
construed to limit the Department' s authority to take or arrange,
or to require any Responsible Party or Potentially Responsible
Party to perform, any response action authorized by M.G.L. c. 21E
which the Department deems necessary to protect health, safety,
public welfare or the environment.
