SUMMARY
PILGRIM l DISCHARGE MONITORING REPORT in accordance with the Federal Clean Water Act, as amended (33USC 1251 et sea: the
" CWA"), and the Massachusetts Clean Water Act, as amsnded (M.G.L.; Chap. 21,26-53),
regarding effluent limitations, monitoring requirements and der conditions set forth in the Pilgrim NPDES Permit (Federal Permit Number MA0003557, and State Permit Number 359),
parts i and il, the following information is submitted for the period April,1995.
l.
Discharae Points Covered in this Report Discharae Point Discharae Identification 001 Condenser Cooling Water 002 Thermal Backwash for Biofouling Control 003 Intake Screen Wash 004, 005, 006, and 007 Yard Drains (April aad September) 008 Sea Foam Suppression 010 Service Cooling Water 011 Makeup Water and Demineralizer Waste Discharge ll.
Summary and Notes of Discharae Report A.
The flow at points 001 and 010 are calculated from system pump capacity and are equal to the total for all pumps in each system running at full capacity for a 24-hour period. The flow at 011 is measured by noting sump levels before and after discharge. Flow at point 002 is a conservative figure obtained by calculating flow if backwashing took place for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Flow at points 003 and 008 are calculated from system pump capacity and mean operating time.
B.
The temperatures at points 001 and 002 are measured by resistance temperature detectors (RTD's).
C.
Periodically, total residual chlorine (TRC) concentration in the service cooling water (010) exceeds Permit requirements (0.50 ppm daily average TRC and 1.00 ppm daily maximum TRC) prior to mixing with any other stream, primarily because of the number of service water pumps in operation. Chlorine injection levels are lowered as a corrective measure. The dilution provided by the PNPS circulating water flow keeps total residual chlorine concentrations discharged to Cape Cod Bay below the NPDES Permit limit of 0.1 ppm.
D.
For stormwater outfalls 004,005,006 and 007, Sigma 800 SL Portable Composite Samplers are utilized. The samplers are equipped with a " liquid level activator" that commences the sampling when the liquid reaches a predetermined level. This assures a sample is taken "within the first hour of the i
I start of a significant storm event." The intake and collection assemblies of the samplers conform to U.S. EPA requirements for collecting oil and grease samples (USEPA letter to BECo dated 1/7/92). No additionalinputs to these stormwater outfalls occur downstream of the composite samplers' sampling locations.
j E.
Intake traveling water screens were operated with dechlorination pumps operating at all times.
F.
No sawdust was applied to seek and seal PNPS condenser leaks in April.
G.
The following boron and sodium nitrite discharges (ppm) occurred in April 1995 from discharge point #001. All discharges were below NPDES Permit limits prior to entering Cape Cod Bay.

On April 3,1995 the USEPA approved a discharge with a pH below the allowable NPDES Permit firnit (6.1) from the PNPS demineralizer waste discharge point (011)(BECo Telecon 4.95.004). The pH in the waste tank was approximately 5.5 but its discharge to Cape Cod Bay, with one circulating water pump dilution, was expected to have no adverse environraental impact.
l.
April 1995 ysrd drain monitoring showed pH values of 5.9 at yard drain #005 and 5.2 at yard drain #006 which are below the lower NPDES Permit Limit of 6.0. This may be attributable to a low natural rainwater pH of 4.4 at that time.
J.
The suspended solids exceeded the NPDES Permit monthly average limit (30 ppm) from the PNPS demineralizer waste discharge point (011) on three separate occasions in April 1995, resulting in a final monthly average value of 53.2 ppm. This was a result of adding caustic to neutralize the pH value within Permit limits: however, the suspended solids never exceeded the Permit allowable daily maximum of 100 ppm.
