Compliance Monitoring Survey
New England Power Company
Salem Harbor Plant
Salem, Massachusetts
1.. Date of Survey
May 14, 1974, through May 16, 1974.
2. Permit Issuance
The permit for New England Power Company (NEPCO), Salem Harbor Plant,
was issued on June 8, 1973. The special conditions of the permit are in
Appendix A. The approximate locations of NEPCO’s ten discharge points
are shown on Figure Bi (Appendix B).
3. Process
At Salem, New England Power Company has the capacity to generate
approximately 800 megawatts of electric power by means of four steam
turbine generators. Four boilers at the plant are fired by oil or coal
(when NEPCO has the required variances).
4. Process Waste
Most waste water from the Salem Harbor Plant is once through non—
contact cooling water from the generating process. Other waste waters
are basically fly ash sluice waters and floor drainage.
Waste water is also generated by boiler cleaning operations which
occur approximately twice a year. There were no active cleaning operations
at the time of the survey.
Description of Water Flow (See Appendix B)
Daily 1,500 to 1,600 m 3 /min (600 to 625 MCD) of salt water is taken
into the plant through an outward flow rotating screen structure. These
screens are continuously backwashed. The backwash and that portion of
the intake water which is not screened passes through a bar rack and
directly out discharge 005 and discharge 007. The screened salt water
is considered the influent to the plant.

-------
2
The influent water is divided for two functions: (1) The major
portion of this flow is non—contact cooling water which is discharged
through discharges 001, 002, 003, and 004; (2) The remaining water is
used to clean out the fly ash sluice at the bottom of each boiler. The
fly ash sluice water combined with various floor drains comprise the
major portion of the flow into the settling lagoons. This water is
referred to as the oil—fired waste.
When coal is being used at the plant, the volume of the sluice
water is greatly increased due to the increase in uncombusted materials
which fall into the sluice. This water is referred to as the coal—fired
waste. The coal—fired waste is discharged to the settling lagoons by
means of a separate discharge pipe. The effluent from the settling
lagoons constitutes the discharge numbered 006.
It should be noted that discharge 008 (City Storm Sewer), discharge
009 (12” Surface Drain), and discharge 010 (21” Surface Drain) were observed
‘but not sampled. Each pipe discharges intermittently based on the
quantity of surface runoff.
6. Existing Treatment
The existing treatment system for fly ash sluice water consists of
three lagoons in series numbered in order of flow, lagoon #1, lagoon #2,
and lagoon #3. These, in the original submission for a permit, were
referred to as settling center, primary settling basin, and secondary
settling basin (as shown in Appendix B).
The coal—fired waste bypasses lagoon #1 and is discharged directly
into lagoon #2. All the waste water from the lagoons passes through a
gravel bank—type filter forming a portion of the wall of lagoon #3 and
then fui nels through discharge pipe #006 before emptying into the
discharge channel. -
7. Summary of Sampling
A suimn ry of station location and sampling is found in Table 1.
Results of testing performed on samples collected at NEPCO are simmiarized
on Tables 2 through 7.
The survey sampling procedures included automatic sampler operation,
grab sample collection, and continuous recording instrumentation. Chain
of custody procedures were employed and analytical support services were
provided by EPA’s New England Regional Laboratory in Needham Heights,
Massachusetts.
Metals were analyzed by i—ray fluorescence spectrometry to give a
qualitative observation of metal concentrations. At all the discharge
locations, only trace metal concentrations were measured. No concentrations
measured, on the samples tested, exceeded the levels established by the
permit special conditions for effluent metal concentration.

8. Observations
At discharges 005, 007, 008, 009, and 010, no discoloration, floating
solids, foam, or oil sheen wereobserved in the vicinity of the discharge
pipe.
During the sampling period two operational upsets (situations not
considered normal operation) were observed: -(1) Solids in the lagoon
were building up causing channelized flow. The excess solids in the
lagoon were caused by the burning of coal rather than oil. (Coal has
a much larger percent of uncoinbustable material.) With two large diesel
shovels working, NEPCO was maintaining status quo in the lagoons. On
May 15, at 2400, NEPCO’s variance to burn coal expired. They anticipated
that within two weeks they would be able to get the lagoons back up to
normal operation; (i.e., the solids all dredged out of the lagoons); and
(2) The pump at the waste water collection sump for discharge to lagoon #1
was not functioning properly causing a èâlids build-up in the sump. The
first day of the survey the sump was cleaned so that a new pump could be
installed on the following day. During the repair period, the existing
pump was switched from intermittent to continuous operation.
These conditions of abnormal operation perhaps contribute to the
high suspended solids reported in Table 4. A summpry of self—monitoring
data, field survey information, and permit conditions is presented on
Table 8 and Table 9. The values measured during our survey compare
favorably with those reported on the discharge monitoring reports (Appendix C).
Our survey, then, confirms the permit compliance evident in the self—
monitoring report.
