General The inspection consisted of a review of the licensee's pre-oper-ational environmental monitoring program for Unit 2 and the oper-ational environmental monitoring program for Unit 1, encompassing both the radiological and non-radiological aspects of these programs.
I The licensee's operational environmental monitoring requirements for Unit 1 are described in Appendix B to the Operating License
,
DPR-50, the Environmental Technical Specification (ETS).
The pre-operational environmental monitoring commitments for Unit 2 are
!
described in the Unit 2 Environmental Report and in the Unit 2 FSAR. Areas examined during this inspection included a selective examination of air, water and gamma dosimetry stations, sampling

and analytical procedures, representative program results and reports, interviews with licensee and contractor personnel, and observations by the inspector.
As part of this inspection, the laboratory facilities of Ichthyological Associates, Inc. (IA) in Etters, Pennsylvania were visited.
!
i In addition, the circumstances, evaluationa and corrective actions relating to the reported Environmental Incident EI 75-09 were ex-
,
amined, and the following TMINS reports were reviewed:
-
Report of Water Quality and Heavy Metals Analysis for 1975 An Ecological Study of the Susquehanna River in the Vicinity of the Three Mila Island Nuclear Station-Annual Report for 1975 Radiological Environmental Monitoring Report for TMINS-Semi-Annual Report - January-June, 1975 Semi-Annual Report - July-December, 1975 3.
Organization and Administration The inspector reviewed the organization and administration of the environmental monitoring programs at the TMINS site and determined that this area was essentially as described in NRC:IE Inspection Report Nos. 50-289/75-21 and 50-320/75-12 and in AEC:RO Report No.
50-289/74-34 at previous inspections of this area.
4.
Radiological Monitoring Program l
}
a.
Air Monitoring j
]
(1) The inspector examined selected air sampling stations and noted that all were operating at the time of the in-i spection.
The inspector observed that the sampling trains and filters used were the same as reported pre-j viously in AEC:RO Inspecticn Report 50-289/74-07.
The j
inspector noted that the sampling heads had been re--
i oriented :nd sheltered such that precipitation did not i
strike the particulate filters.
(2) The inspector letermined that the licensee did not have prepared, written procedures as required by ETS 5.5.1.j for the analysis of background and indicator station air samples for I-131 and radioactive particulates.
The inspector stated that this was an item of noncompliance.
The inspectot examined the licensee's Surveillance
' Procedure SP L301-9.4 and noted that it did not provide sufficient in.itructions to ensure that its implementation would assure compliance with the ETS.

(3) The inspector further determined through the review of the available records and reports and through discussions with the licensee that the quarterly compositing of the weekly air particulate filters was not done in accordance
with the requirements of ETS 4.4.a, Table 3.
This Table
'
requires that the weekly filters from eight indicator
,
!
stations and the weekly filters from the one background station be composited as two samples-indicator and back-ground, respectively, for gamma spectral analyses.
The inspector determined that two stations (one an indicator)
!
were used in compos _iting the background samples for the j
past 1 1/2 years in noncompliance with the requirements.
(The inspector noted that the ETS had been recently I
amended as of July 23, 1976 to allow the compositing of
'
filters from three weekly air sampling stations for the quarterly background gamma spectral analysis and from five sampling stations as the " indicator" samples.)
'
(4) The inspector reviewed the licensee's air particulate and air iodine results since January, 1975 and determined
'
that with the exception of the method of compositing the
,
background and indicator sampics, all the analyses appeared to have been performed, as required.
The inspector Q-discussed with the licensee an apparent discrepancy between the ratios of indicator / background gross beta
,
activities and those of the gamma spectral activities.
The licensee stated that this would be evaluated.
This item is unresolved pending subsequent review of this
'
area.
b.
Precipitation Sampling (1) The inspector examined selected precipitation collection stations and observed the monthly collections at these stations.
The inspector discussed with the licensee the sampling and collector rinse procedures.
The licensee stated that these areas would be reviewed.
The inspector
,
noted that the ETS did not specifically require approved
,
procedures for this area, therefore had had no further questions.

The inspector determined from the review of the Sur-veillance Procedure SP 1301-9.4 input, discussions with the licensee, and review of the records that all the required precipitation samples were collected since i
January 1975.
The inspector also reviewed the sampling procedure and noted that it did not contain compositing procedures, nor was it approved.
(The inspector further
,
noted that the ETS did not specifically require approved procedures for this area.) The inspector determined through discussions with the licensee and contractor that
,
the required quarterly analyses were made on propor-tionally composited samples.
The inspector had no further questions in this matter at this time.
(3) The inspector reviewed the results of the gross beta analyscs of precipitation since January 1975 through the latest available results (June 1976) and found no in-adequacies in this area.
(4) The inspector examined the results of the quarterly gamma
.
spectral analyses and the semi-annual Sr-89 and 90 analysis
'
for the same time period.
With respect to the Sr-89 and 90 analyses of precipitation samples, the inspector noted ()
that at times the reported results approached the re-quired minimum sensitivities for these analyses.
Since the strontium chemical yields and other necessary data
were not available to verify the reported results and because the Sr-89 results were not corrected for decay over the long compositing interval, the inspector stated that the sensitivity of Sr-89 and 90 analyses of pre-cipitation was considered unresolved pending the ac-quisition and review of this data.
The licensee indicated
!
that this data would be obtained and available for review.
-
c.
TLD Measurements The inspector examined selected TLD monitoring stations and examined the records of the results of the TLD program at TMINS since January, 1975.
The inspector also reviewed the results of the TLDs utilized as a quality control of the
'
primary contractor.
The inspector discussed with the licensee the TLD annealing, preparation, calibration, utilization, and
,
control procedures.
The licensee stated that these areas would be re-examined.
The inspector noted that the ETS did not specifically require approved procedures for this area, therefore, the inspector had no further questions in this regard at this time.

River Water The inspector examined selected river water sampling stations
,
and observed the water sampling procedures.
These areas were i
discussed with the licensee, as well as, the near downstream sampling stations in terms of representing the bulk of the river flow.
The licensee stated that alternate sampling locations and frequencies were being evaluated for possible
{
ETS changes.
The inspector reviewed the results of the river water sampling and analytical program since January, 1975.
The inspector also examined the circumstances surrounding licensee's reparts of I-131, Co-60 and H-3 (or several occasions) in excess of four
-
times or ten times the control station values.
(See SUMFMRY OF FINDINGS, Unusual Occurrences, Items A and B).
The inspector also reviewed the pertinent liquid discharge records and dis-cussed the frequency, location and timing of the river samples in terms of their representativeness of the river.
The inspector
had no further questions in this area at this time.
I e.
Fish and Bottom Sediments (' )
The inspec*or discussed with the licensee the sampling and analytical procedures for fish and for bottom sediments.
The analytical results for these media were reviewed since January, 1975. The inspector determined that the requirements
,
in these areas had been met, with the following exception:
,
Sr-89 and 90 analyses of both fish and bottom sediments were not of sufficient sensitivity to meet.the requirements of ETS 4.4.a, Table 3.
The licensee identified this as an item of noncompliance and submitted a proposed ETS change in July, 1975 which would relieve the sensitivity requirements to thsoe more reasonably achieveable.
This change was approved in July, 1976 by Amendment No. 18 to the ETS.
(See SUM!ARY OF FINDINGS, Infractions and Deficiencies Identified by the Li-censee, Deficiencies, Items 1. a. and 1.b. ).
The inspector had no further questions in this area at this time, i
The inspector also reviewed the circumstances surrounding the reports of Cs-137 and Co-58 in sedimerrs in excess of four times and ten times, respectively, those at the control stations.
(See SUMMARY OF FINDINGS, Unusual Occurrences, Item C.)
The inspector had no further questions in this area.

Vegetation The inspector reviewed the licensee's records of the results of
-
the green leafy vegetation sampling since January, 1975 and discussed them with the licensee.
The inspector determined that all the requirements in this area appeared to be met with
,
i one exception.
The licensee had determined that the analytical sensitivity for measuring I-131 in vegetation was consistently I
less than that required by ETS 4.4.a, Table 3.
(The inspector noted that the licensee submitted a proposed change to the ETS in this regard in July, 1975.
The change was approved in July, 1976 by Amendment No. 18 to the ETS.
(See SUMMARY OF FINDINGS, Infractions and Deficiencies Identified by the Licensee, Deficiencies, Item 1.c.) The inspector had no further questions in this area at this time.

g.
Milk
.
The inspector reviewed the results of the milk sampling pro-
,
gram ct TMINS since January 1975 and determined that all the
'
required samples were collected and analyzed with sufficient
'
sensitivity to meet the requirements of the ETS.
The inspector also reviewed the results of the latest milk animal census and ()
discussed them with the license'e.
The inspector had no further questions in this area.
5.
Quality Control of the Radiological Environmental Monitoring The inspector reviewed with the licensee the licensee's quality i
i control program, the program policy and philosophy, and represent-
.
ative program results.
In summary, the licensee uses some dupli-I cate samples and sampling stations for each media and a second analytical laboratory to evaluate the quality of analytical per-
'
formance.
The inspector discussed the use of split samples rather than duplicate wherever practical.
The inspector also examined the licensee's audits of one of the contractors, the audit findings, recommendations and resulting followup action.
The inspector had no further questions in this area at this time.
6.
Chemical and Thermal Monitoring a.
Thermal The inspector examined selected thermal monitoring records and reviewed the procedures for operation of the mechanical-draft cooling tower.

(See SUMMARY OF FINDINGS, Infractions and Deficiencies Identified by the Licensee, Deficiencies, Item 2.) Changes to the procedures for operating the mechanical cooling tower as a result of this event were reviewed and discussed with the licensee.
The inspector had no further questions in this i
i area at this time.
b.
Chemical Discharges I
(1) pH The inspector examined the licensee's Procedure 1104-18,
'
Rev. 7 for the discharge of the contents of the waste neutralizing tanks and verified that it contained pro-visions to assure that the tank pH was within the limits i
of ETS 2.2.3 prior to release.
l
!
The inspector examined each of the waste release records i
for April 1 through June 30, 1976 and selec_ tad records outside this interval.
For those releases during the intervals examined, no discharge was made in which the pH was outside the ETS 2.2.3 limits.
,
f
{}
(2)
Dissolved Solids The inspector examined Procedure 1104-18 Rev.-7 and verified that it contained provisions to assure that the requirements of ETS 4.2.1, concerning dissolved solids in plant river water discharges, are met.
1 The inspector reviewed each of the licensee's discharge
records for the interval May 1, 1976 through June 30, 1976 and selected other intervals and determined that the dissolved solids for each of the discharges examined were within the ETS 4.2.1 limits.
The licensee stated that an analysis of the above data to determine the effects of plant operation on river water chemistry has not yet been performed.
The inspector noted that.the ETS did not specifically require that this be done.
The inspector had no further questions in this area at this time.
c.
Chlorine The inspector reviewed with the licensee the chlorination procedures, frequency and duration, and analytical procedures
-
and results for 1976.
No instances were noted in which the i)
total residual chlorine concentration er.ceeded the ETS 2.2.1

The inspector also reviewed the draft report of the special
\\
chlorine study performed at TMINS by WAPORA, Inc., Washington,
'
D.C. and discussed the reported findings with tha licensee.
The licensee stated it would be several months before the final report is completed and evaluations could be made of its possible implications in terms of optimum utilization of chlorine or other biocide at TMINS.
The licensee stated that the resulta of the study would be used to try to optimize the
{
plant cleanliness with minimum environmental degradation.
d.
Sulfate Ion
,
i The inspector discussed with the licensee the method of main-taining ins antory and log records to. show the quantity of sulfuric acid used it. demineralizer regeneration and in circ-ulating water such that the total quantity of sulfate ion released from these uses does not exceed 4,620,000 pounds /
year.
The inspector also reviewed the records for 1975 and determined that the sulfate discharges were within the ETS
<
i 2.2.2.b limits on a calender year basis.
Running 12 month
!
inventory totals were not maintained.
The licensee stated that the method of determining the usage would be evaluated for obtaining periodic use status during the year.
The inspector stated that this would be considered unresolved pending completion of the 2icensee's evaluation.
7.
Environmental Surveillance and Special Studies
a.
Fish Impingement The inspector reviewed the results of the fish impingement orogram for 1975, and selected. sampling and analytical pro-cedures for this program.
The licensee stated that the impingement program required by ETS 4.1.1.A was officially terminated by TMINS as of June 1, 1976.
The licensee does, however, continue the semi-monthly sampling program, but at l
ei ht hour rather than four hour intervals over a 24-hour b
period.
<
b.
Entrainment of Fish Eggs and Larvae The inspector reviewed the results of these programs through October, 1975, at which time these programs were terminated by
!
TMINS.
Selected sampling and analytical procedures were discussed with the licensee and contractor personnel.
,
The licensee stated that beginning in March, 1976, the plant intake was sampled twice monthly using a net to obtain a sample rather than the pumping technique used earlier.
In addition, 13 stations in the reservoir are sampled to es-tablish a population base in the river.

The licensee stated that this program had been terminated in accordance with the ETS at the end of October, 19/5.
The inspector stated that items a., b., and c. above are considered
,
j unresolved pending NRC review of the results of these studies.
The inspector stated that while ETS 4.1.1 allowed the termination of these programs at the end of the second year; it appears that the termination of these programs are contingent cn a satisfactory NRC staff review of the results from the first year.
Since that staff review had not been completed, these items are lef t unresolved at this time.
The licensee stated that since nothing had been heard to the contrary from the NRC, the program was terminated after the scheduled time and the licensee was using this time to perform other baseline studies to establish a more meaningful monitoring program for Unit 2.

Fish Survey
.
The inspector discussed with the licensee and contractor the (])
methodology and results of the Yish sampling program.
The licenses stated that in addition to the required trap netting and shore seining required-by ETS 4.1.1.D, electrofishing and creel census were performed in an effort to improve the fish population estimates in the Susquehanna River.
This program will continue for one more year, pending review of the NRC staff.
The inspector had no further questions in this area at this time.
e.
Macro-invertebrates
.
The inspector reviewed the results of the macro-invertebrate sampling program for 1975 and discusred with the licensee and contractor personnel the sampling, auf analytical techniques, including the use of keys for ideni.ification, and sampling and analytical variability.
The inspe: tor had no further ques-tions in this area at this time.
.
f.
Cooling Tower Salt Drift Study The inspector observed the methodology of the visual inspec-tion of natural vegetation and crops to determine if any physical damage resulting from cooling tower salt drift is
,
occurring.
The inspector discussed these methods with the
,
licensee and contractor and reviewed the results of the pro-
,
_
gram for 1975.
The inspector had no further questic s3 $ r$h%g g area at this time.

Heavy Metal Analysis The inspector discussed with the licensee the sampling and analytical procedures utilized to determine the heavy metal content at the plant river water discharge and upstream of the plant river water intake.
The licensee stated that Surveillance Procedure SP 1304-3 was utilized'to assure that each of the j
required samples were collected and analyzed, and that the sampling and analytical procedures were maintained by the Contractor.
The inspector verified from the surveillance records that each
,
of the required heavy metal analyses were performcd for the I
months I.pril through June, 1976.
The licensee stated that the i
resulte of the heavy metal analyses had not yet been reviewed to determine if plant operations had any effect on river water chemiatry.
The inspector had no further questions in this area at this time.
8.
Performance Evaluation in the Biological / Aquatic Studies
!
The inspector discussed with the licensee and contractor personnel the evaluation of the quality of performance in the biological /
()
aquatic studies; including the determination of variability in subsampling, in analytical techniques, in repetitive samples, in identification of organisms, etc.
The licensee stated that these areas would be evaluated and that in the area of water quality
l analysis, a sample splitting program had been initiated with a
-
second analytical laboratory.
(The results of this program were not yet available at the time of inspection.)
The inspector also discussed the use of documented contractor audits in assuring all the requirements were being met.
The licensee stated that this area was also being evaluated.
The inspector noted that the ETS did not contain any requirements in
,
this area and therefore had no further questions at this time.
9.
Non-Routine Reports The inspector reviewed each of the non-routine environmental i
!
reports submitted since the last inspection of this area.
(These reports have been identified in SUMMARY OF FINDINGS,
'
Unusual Occurrences and Licensee Identified Infraccions and Deficiencies, Deficiencies, Item 2.)
The inspector noted that no nonradiological non-routine reports had been required in 1976 as of the time of inspection.
The inspector had no further questions in the above areas at this time.

Transformer Area The inspector discussed with the licensee the proposed modification of the Unit 1 transformer areas to provide a means of preventing the discharge of oil from this area in the event of a transformer
,
rupture.
The licensee stated that the engineering drawings have
'
been made for these changes and that the actual modifications to
the transformer platform / pit areas would be completed this fall.
With respect to the Unit 2 transformers, the inspector determined that the licensee has a surveillance program to assure that the
!
transformer pits do not fill with water and reduce their ability to contain the transformer oil in the event of a major spill.
The inspector stated that he had no further questions in this area at this time and that the progress on Unit 1 transformers would be j
reviewed during a subsequent inspection.
11.
Construction Activities-Unit 2 I
The inspector toured the Unit 2 construction area and the liquid j
discharge points for the site.
The inspector observed that there i
was no indication of erosion products being carried offsite.
The I
licensee stated that when construction is completed, landscaping h,
and permanent revegetation will be done.
The licensee stated that routine surveillance of the construction areas is conducted by l
plant and corporate personnel.
The inspector had no further questions in this area at this time.

Unit 2 - Environmental Instrumentation Status The inspector examined the status of the Unit 2 instrumentation for
,
j limiting or monitoring chemical and thermal releases and for pro-
'
viding meteorological data to the Control Room.
The inspector observed that the pH monitoring instrumentation for the waste neutralizing system, the intake and discharge water temperature instrumentation, and the meteorological data recorders had been i
'
installed.
The operability and cal.ibration of this equipment has not yet been determined.
This area will be further reviewed during subsequent environmental inspections.
