Environmental Protection - Management Controls Procedure AP-1, Responsibilities and Authorities, specifies that the CRS shall, " Execute and review environmental monitoring programs, the radioactive discharge control program, and the radwaste handling program." This responsibility is further delegated to the SCRA assigned to environmental matters and the clerk responsible for sample collection.
Surveillance Procedures SP 212.01A, Non-Radiological Environmental Protection Surveillance, and SP 212.01C, Radiological Environmental Surveillance, provide Technical Specification (T.S.) Appendix B based checklists which are used to verify the collection of required samples by sample number and date.
The surveillance record is reviewed and initialed by the environmental SCRA.
In addition, SP 212.01C provides for documentation of a review sequence of vendor supplied analytical results. The licensee's environmental surveillance records and analytical review records for the period June 1,1979 through March 31, 1982 were examined.
It was noted that one algae sample (2/27/80) was not collected because of weather conditions; further, a number of environmental TLD results were lost due to vandalism or as a result of high winds and the accidental X-ray exposure of TLDs in the plant security package examination facil ity.
The licensee has taken administrative steps to avoid future X-ray exposure occurrences.
Procedure AP-22, Reporting of Abnormal Occurrence, requires documenta-tion and submission of reports of possible T.S. or procedural violations, to the Technical Assistant, Nuclear Operations for evaluation of reportability and review by the Plant Review Committee.
All AP-22 reports for the period 1979 to the date of the inspection

fio items requiring reports to the Commission pursuant to the T.S. which had not already been reported were identified.
The licensee has established procedure AP-308-8, Panasonic TLD Reader, which provides for annual calibration of the reader and variance checks of all environmental TLDs each quarter before placing the TLDs in the field. The records of environmental TLD results and calibrations are maintained in a notebook entitled,
"SMUD TLD Results 1979 to
" which was examined.
The
,
variance checks g7TLDs are based on TLD response to a 25-30 mrem exposure to a Cs sealed source.
The exposure is verified using a calibrated condenser R-meter.
The variance of the lot of TLDs used for environmental monitoring must be 7.5% or less.
The licensee's environmental program is subject to approximately bi-annual QA audits by the quality assurance department.
The audits, based on MSRC checklist No.16, are normally conducted by a team which includes technically qualified individuals.
The audits address both the radiological and non-radiological environraental monitoring programs.
The following audit reports, covering the period July 1978 to December 1981, were examined:
0-248, 0-272, 0-317, 0-345, 0-378, and 0-434. The reports identified a number of items for which corrective action was required; however, none of the items were indicative of noncompliance with regulatory requirements.
In October 1980, an onsite audit (0-331) of the environmental radiological analytical contractor, Controls for Environmental Pollution Inc. (CEP), Santa Fe, New Mexico was conducted.
The three-person audit team 11.ncluded two technically qualified individuals.
.The audit report indicated that the audit was comprehensive and thorough. No signiff ant adverse findings were identified.
Copies of audit reports are routinely provided to members of the Management Sa fety Review Committee (MSRC).
The audit reports documented routine follow-up of previously identified problems.
No items of noncompliance or deviations were identified.
3.
Environmental Protection - Quality Control of Analytical Measurements With the exception of the environmental TLD program, the licensee relies on a contractor (CEP) for analysis of radiological environ-
. mental samples. With respect to CEP, the SMUD audit (0-331) of October 1980 addressed the use of standards, spikes, cross checks, blanks, inter-laboratory calibration, and reagent standardization for chemistry (water quality), radiobioassay, and environmental chemistry. Additional topics included instrument calibration, quality control, quality assurance surveillance, particular work methods, procedure requirements, reports and record requirements,

and required licenses and certifications.
The audit established that the CEP Quality Assurance Manual had been revised effective December 1979 iThe audit findings concluded that the audit had evaluated all aspects of'CEPs operation in depth and found it to be professional with many improvements since the last audit.
The licensee's procedure AP-306,~ Section VIII, Quality Control -
Secondary Chemistry, Radiochemistry and Counting Room, specifies personnel qualifications and responsibilities.
Further, it documents the r_equirements for. laboratory records, sampling procedures, measurement / analysis; instruments', quality control procedures, training,and-internal; audits.
No items of noncompliance or deviations were identified.
4.
Environmental Monitoring Program Implementation The inspector examined environmental sampling surveillance records, records of reviews of CEP reports, selected portions of CEP quarterly reports, and Annual Environmental Operating Reports for 1979, 1980, and 1981.
During the period for which records were examined, a number of environmental samples reached or exceeded the T.S. report-ing level. These matters were reported pursuant to T.S. ~Section 5.6.1 as required.
The inspector accompanied a member of the SMUD staff during a weekly autine environmental sample collection trip.
The sample points Included milk from the Borges, Van Warmerdam and Medeiros dairies and the single family cow nearest the plant, inplant drinking water, surface and runoff water from the Folsom South Canal, on-site reservoir, and Camanche reservoir and a plant effluent sample.
The particulate-iodine sampler at Camanche Dam was observed and found to be operating properly.
The sampler incorporates an operating hour meter. The sampling program was 'well planned and efficiencly conducted.
Reusable wooden boxes are used to ship samples by air to CEP on the day of collection.
During the tour of
sampling stations, a number of environmental TLD stations were observed.
No items of noncompliance or deviations were identified.
6.
Plant Tour and Independent Vaasurements During the inspection, the containment was toured.
The location where work on the HPI Thermal Sleeves was in progress and the manway giving access to the Auxiliary Feed Ring were observed.
i Independent measurements of licensee posted radiation levels in containment were made using a Keithly ion chamber Model 36100, NRC No. 008917, S/N 1044 due for calibration October 23, 1982.
