-5-The inspector toured the environmental sampling locations, which included sampling stations for the collection of air, broadleaf vegetation, milk, and water samples with an environmental specialist. The location of thermoluminescent dosimeters was also noted. The inspector noted that air sampler equipment in use was properly calibrated and operational. A timing device was used on each air sampler to track operation history. Samples were properly prepared for shipment to a vendor laboratory for analyses.
c.
Conclusions The licensee maintained sufficient supplies and spare environmental sampling equipment to perform the activities described in the Offsite Dose Calculation Manual. Environmental monitoring stations were properly maintained with operable and calibrated equipment.
R2.2 Meteoroloaical Monitorina Eauioment (84750)
a.
Inspection Scooe The inspector observed the meteorological instrumentation at the meteorological towers and reviewed the associated calibration records to ensure that the meteorological instrumentation on the towers was operable, calibrated, and maintained in accordance with written procedures, the guidance in Regulatory Guide 1.23, and Updated Final Safety Analysis Report, Section 2.3.
b.
Observations and Findinas i
The inspector toured the meteorological tower with licensee technicians responsible for performing periodic calibrations of the monitoring equipment on the towers. The licensee maintained a primary tower with monitoring instrumentation at the 10 and 60 meter levels, and a backup tower with instrumentation located at the 10 meter level. The instrumentation at these levels included wind speed, wind direction, and temperature sensing instrumentation. Instrumentation, including recording and transmitting equipment, was noted to be in good operating condition. Daily channel checks, physical inspections, and semi-annual calibrations were performed on the rneteorological instruments.
The inspector noted that the instrumentation agreed with Regulatory Guide 1.23 recommendations and the licensee's Update Final Safety Analysis Report, l
Section 2.3. The inspector noted that allinstrumentation was operable and properly l
calibrated. Calibration records indicated that the instrumentation was maintained
~
'
properly and calibrations were performed at the proper frequencies. Daily channel checks were performed in accordance with operations procedure requirements.
Operation of the meteorological towers resulted in data recovery rates of 93.8 percent for 1995, and 93.5 percent for 199 _

Observathns and Findincs
)
Revisions 13 and 14 to the Offsite Dose Calculation Manual had been issued since the last inspection. The changes affecting the radiological environmental monitoring program were only to clarify sample analysis frequencies. The inspector noted that the changes did not result in a decrease of the effectiveness of the Offsite Dose Calculation Manual. The implementing procedures described the responsibilities for collection, documentation, and shipment of environmental media samples collected around the Comanche Peak site. The licensee's procedures were written with sufficient detail for conducting the required radiological environmental monitoring program activities. No concerns were identified in the review of the environmental procedures.
c.
Conclusions The licensee had made minor changes to the Offsite Dose Calcolation Manual.
However, these changes did not decrease the effectiveness of the radiological environmental monitoring program. Radiological environmental monitoring program implementing procedures containing sufficient detail were used.
R4 Staff Knowledge and Performance a.

Observations and Findinos
,
Management of the radiological environmental monitoring program was performed by the radioactive materials control group of the radiation protection department.
'
No significant changes in the organization were noted since the last inspection; however, the licensee expected changes to occur in the near future. Two individuals were responsible for the majority of the collection and preparation of the
)
environmental samples, including the review of the sample analysis results and
,
preparation of the annual reports. As a result of a planned future re-organization of the radiation protection department, other personnel are to be designated as having l
responsibilities in the radiological environmental monitoring program. These j
individuals would be trained in accordance with licensee procedures.
