I. Introduction The 1992 Palisades Nuclear Plant Annual Radiological Environmental Operating Report provides a summary and data interpretation of the Palisades Radiological Environmental Monitoring Program as conducted during the 1992 reporting period. Reporting requirements are detailed in Palisades Offsite Dose Calculation Manual, Appendix A, sections III.J and IV.B, tables E-1 thru E-3, and table F-1. Palisades was off-line February 7 to April 19 for reactor refueling. The plant was off-line July 1 to July 4 and July 24 to July 29 due to Turbine Control System problems. The plant was off-line August 14 to August 17 due to a failed air line to a feedwater regulating valve and problems with the Turbine Control System. The plant was taken back off-line August 17 to August 18 due to a turbine hydraulic fluid leak. The plant was off-line August 25 to August 27 due to a failed solenoid in the preferred AC bus powering enineering safeguards system electrical loads coupled with an undetected blown fuse. The plant was taken off-line September 19 to September 28 for the investigation of a personnel injury accident. The plant was off-line again October 30 to November 8 due to Turbine Control System problems. There are no remaining 1992 laboratory sample analyses pending completion for inclusion into this report. The results of all environmental samples collected are evaluated as follows: A. Air iodine and particulates, TLDs (monthly and quarterly), and milk data were statistically evaluated at the 95% confidence level (using SAS program) by the methodology detailed in Palisades Procedure HP 10.4. The data was compared against two criteria: the first criterion is the statistical difference which determines if sample results from near sites are significantly greater than those from control sites. The second criterion is the evaluation level (twice the statistical difference) which is the minimum detectable difference that exceeds zero at the 95% confidence level. If the evaluation level is exceeded, then correlation of the results with effluent releases is done. B. Well water, lake water, sediment, fish and other aquatic biota samples were evaluated using data means comparisons against an appropriate control location (if available) and Palisades Technical Specification limtts. II. Reportable Event None III. Discussion and Interpretation of Results A. Air Sample Comparison of the gross beta airborne particulate sample data between near-site and control locations did not exceed the statistical difference. In many instances, control location sample values were greater. There was no I-131 activity reported above LLD. A total of 625 air samples were collected and analyzed during 1992. Five sample results were not included in the statistical evaluation. Refer to Enclosure A for specific reasons for sample rejection. The samples deleted constitute 0.8 percent

of the Iodine-131 and air particulate gross beta total. Palisades ODCM, Appendix A, sensitivities were met on all samples other than those noted. Air iodine/particulate samples are collected on a weekly basis from twelve (12) air sampling locations. Air is metered into the sampling unit at a continuous 1 cfm flow rate through a Gelman 47mm air filter (air particulate) and a Scott air iodine cartridge. Both filters are in-line with each other and housed within the same filter holder. The 1992 air sampler results are consistent with actual effluent releases and site-specific meteorology. B. Lake Water A total of 36 individual monthly lake water composite samples were collected from three (3) locations during 1992. Lake water samples from the Palisades Lake-in (intake), the South Haven Municipal Water system intake (raw water), and Ludington Lake-in (intake) are collected daily and composited into monthly samples. Evaluation of the monthly lake water analytical results was based on a data means comparison between the Palisades Lake-in (indicator), the South Haven Municipal raw water (indicator) and Ludington Lake-in (control) locations. The lake water results were also evaluated against the Palisades Technical Specification reporting limits. Gross beta analyses are required for all lake water samples. The Palisades Lake-in, South Haven Municipal raw water, and Ludington Lake-in samples were below the required LLDs for gross beta. Monthly gross alpha and tritium analyses were also performed on the Palisades Lake-in and Ludington samples for comparison data against the Lake-out (discharge) sample results. Results of the gross alpha and tritium analyses were below LLD. No Palisades ODCM reporting limits were exceeded. Although the lake-out (discharge) sample is not used as an indicator in the Radiological Environmental Monitoring Program it is monitored for activity. Four times during 1992 the tritium activity for the discharge was above the ODCM action level of 1000 pCi/L. These elevated levels were all correlated to liquid effluent discharges and were confirmed by comparison to calculated effluent tritium concentrations. Palisades Lake-in, South Haven Municipal and Ludington Lake-in water samples are collected daily for composite into a monthly sample. One-gallon of Palisades Lake-in water and two gallons each of South Haven Municipal water and Ludington Lake-in water are sent to Teledyne Isotopes for analysis. No treatment of the water samples with preservative is required. C. Drinking water A total of 36 individual monthly drinking water samples were collected from the South Haven Municipal Water System and Ludington Pump Storage Water System during 1992. The South Haven samples are obtained from two collection points: South Haven Municipal Water System intake (raw water) and South Haven

Municipal Water System treated water. The Ludington samples were collected from one collection point, the tap from well water. Samples are collected daily for composite into a monthly sample,

  • for the South Haven raw and treated water samples, and a monthly grab sample is obtained for the Ludington well water sample. The South Haven samples are used as indicating locations and the Ludington samples serve as controls.

Evaluation of the drinking water analytical results was based on historical data and a data means comparison between raw water and treated water, as well as a comparison to the Palisades ODCM reporting limits. The evaluated data was also trend plotted against the Palisades Lake-in gross beta results. The indicator and control drinking water samples require both gross beta and tritium analysis except for the South Haven Municipal raw water sample, which only requires a gross beta analysis. For all samples, including Ludington, the analytical results were below LLD for gross beta and tritium. No special or supplemental analyses were required during 1992. A two-gallon quantity of each sample is sent to Teledyne Isotopes for analysis. No treatment of the water samples with a preservative is required. D. Well Water A total of 96 monthly well water samples were collected from eight (8) locations during 1992. The Palisades site well (indicator) is collected daily and composited into a monthly sample. The State Park and Covert Township Park well water samples (controls) are collected as monthly grab samples only. From five other site area wells (indicators), one (1) sample is collected from the warehouse building (WH), one (1) sample is collected from the outage building (OB) and one (1) sample each is collected from the monitoring wells #14, #15 and #16 which were installed to monitor the groundwater around the Steam Generator Storage Facility. The twelve drinking water samples from the Ludington site well (32-LP) also serve as controls. These six (6) sample points (WH, OB, #14, #15, #16 and 32-LP) are sampled once a month by grab sample. Evaluation of the well water analytical results was based on a data means comparison between the six (6) indicator locations and the three control locations as well as with the Palisades ODCM reporting limits. Tritium and gross beta analyses are required for the well water samples. Analytical results were below LLD for tritium at all locations and below LLD for gross beta at the Palisades site, the State Park, Covert Township Park, the Outage Building and Ludington Pump Storage which are drinking water wells. The Warehouse well had a mean of 5.3 pCi/L gross beta, and monitoring wells #14, #15, and #16 had means of 4.8 pCi/L, 5.4 pCi/L and 4.7 pCi/L, respectively. The means for these four wells are slightly above* the 4.0 pCi/L gross beta LLD and are consistent with the mean data for 1991. It should be noted that the Warehouse well and monitoring wells #14, #15, and #16 are not used for drinking. 

                       '1 No Palisades ODCM reporting limits were exceeded for the 1992 well samples. The December site well #14 sample exceeded the gross beta ODCM action level of 10 pCi/L. The December result was 11.2 pCi/L. The result was verified by re-analysis and the necessary supplementary analysis were completed except for an I-131 analysis. The supplementary analyses were all less than LLD. An I-131 analysis is a HP 10.1 procedural requirement not a Palisades ODCM requirement. This deviation was documented by Palisades corrective action system Deviation Report D-PAL-93-026. Site well
    #14 typically trends around 4 to 8 pCi/L and it is not unusuaal for it to exceed the 10 pCi/L action level. A similar trend in the gross beta activity level for site well #14 was observed at about the same time last year.

One (I) one-gallon quantity from the on-site well and two (2) one-gallon quantities of sample for each of the other wells are sent to Teledyne isotopes for analysis. No treatment of the water samples with a preservative is necessary. A total of 48 individual monthly milk samples were collected from 4 different dairy farms (stations 26-FC, 27-KK, 28-GH and 29-WS) during 1992. The milk samples are obtained as grab samples (from dairy milk holding tanks). With the exception of Sr-90, all isotopic results listed in Table 10.4-2 were less than LLD. SAS evaluation of the Sr-90 activity between indicator (26-FC, 27-KK, and 28-GH) and control (29-WS) locations revealed a statistical difference between the indicators and controls, but the difference did not exceed the evaluation level. The indicator. loc~tion (26-FC) had the highest annual Sr-90 mean for 1992 of 3.7 pCi/L. The control location (29-WS) had an annual mean of 2.3 pCi/L. These results are relatively unchanged from 1990 and 1991 results. The difference is not considered significant at these very low values. No special or supplemental analyse~ were required, nor were any Palisades ODCM reporting limits exceeded. Milk samples are required monthly (usually collected the 1st week of the month) from each designated location (4 total). Two one-gallon quantities of raw milk (grab sample) are obtained per sample location in order to meet analytical requirements. Each sample quantity is treated with a sodium bisulfite (40 grams per gallon ) preservative prior to being sent to Teledyne Isotopes. F. TLDs - Gamma Dose There were a total _of 344 monthly, 114 quarterly and 26 annual TLDs collected and analyzed during 1992. Four (4) monthly TLDs, two (2) quarterly TLDs, and three (3) annual TLD were reported missing. Refer to Enclosure A for further details. The Palisades gamma assessment program consists of 30 locations: I directly on-site, 9 inner ring and 6 Steam Generator Storage

  • Facility TLDs for a total of 15 site boundary, 10 outer ring (1.0 to 5.5 miles out), 3 control (30 to 55 miles out) and I TLD control placed in a lead storage cave. For 1992, the average monthly gamma readings were: 3.8 mR for the inner ring TLD's (site boundary) 4.7 mR for the outer ring TLD's (1.0 to 5.5 miles

out), and 4.5 mR for the control TLD locations. The results are consistent with actual effluent releases. The one (1) on-site TLD location (ST-1) serves as an individual reference TLD, however it was evaluated along with the inner ring (site boundary) TLD's in the SAS program. The monthly and quarterly SAS statistical TLD data evaluation were accomplished by comparing the inner ring TLDs (site boundary locations ST-01, ST 13-21 and ST 33-38) and the outer ring TLDs (locations St-02 thru ST-09, ST-23 and ST-24) against the control TLD locations (ST-10 thru ST-12). The annual TLD data evaluation was done by direct comparison of data points only. No monthly or quarterly statistical differences were exceeded. In comparing the inner ring TLDs to the control TLDs ST-11 (Kalamazoo, 34mi SSE) had the greatest monthly mean of 4.8 mR. ST-35 (ENE Site Boundary) had the greatest quarterly and annual exposure of 13.6 mR and 59.0 mR, respectively. When the same comparison was made between the outer ring and control location TLDs, ST-02 {Tower Hill, 5 mi. S) had the greatest monthly, quarterly and annual data mean for any indicator location of 5.6 mR, 17.2 mR and 69.9 mR, respectively. Environmental gamma doses are measured monthly, quarterly and annually by placement of 3 TLD badges per designated location. Each Teledyne TLD badge contains a 4-zone CaS04 wafer (the wafer also includes an additional backup/reserve readout zone). Sensitivity for the multi-zone TLDs are 0.5 mR with a linear response of 0.1 mR to 1000 R.

  • G. Crops The collection of food crops and vegetation samples (when available and in season) is a requirement of the Palisades Radiological Environmental Monitoring Program. Two principal area crops, apples and blueberries, are regularly collected as specified in the ODCM. While there are no designated locations where food crops are collected, samples are generally obtained from the same areas where the air monitoring stations are located within the ESE, SE or SSE sectors. The collection of food crops assists in verifying stack effluent deposition patterns.

During 1992, 10 crop samples were collected from two stations (6 samples from station ST-04, 3.5 mi SE and 4 samples from station 5-PR, 3.5 mi ESE). Evaluation of sample analytical results was direct. There was no control location used. Of the isotopic analyses listed on Table HP 10.4-2, only the gross beta resulted in any specific activity {slightly above LLD). All other analyses were less than LLD. The crop samples at station ST-04 had the greatest individual means for gross beta activity of all 10 samples taken. No Palisades ODCM action or reporting levels were exceeded, nor were any special/supplemental analyses required during 1992.

Food crop samples are required to be collected when available and in season. When collected, approximately I Kg of sample is placed in a sealable plastic bag for shipment to Teledyne Isotopes. No special treatment of the samples with a preservative is necessary. H. Sediment

  • A total of II individual sediment samples were collected from 5 locations during I992. Eight (8) sediment samples were obtained from Palisades (discharge, %mi South of discharge, %mi North of discharge and South Haven Beach locations) and three (3) samples from the Ludington*Control Station.

Evaluation of the sediment analytical results was based on a data means comparison between Palisades and the Ludington control samples as well as the Palisades Technical Specification reporting limits. The individual Palisades sample locations were combined into one indicator (site) location for comparison purposes; however if any one individual sample location had a greater specific isotopic annual mean than the other location(s), then that location is identified on Table HP 10.4-2. Of the isotopic analyses listed on Table HP I0.4-2, only gross beta activity was detected at levels above the required LLD level. Location 25-SH (South Haven Beach) had the greatest mean for gross beta. No Palisades ODCM action or reporting levels were exceeded, nor were any special/supplemental analyses required during I992. Sediment samples are collected semi-annually from each designated location. A one (I) liter quantity grab sample usually is obtained off-shore. No treatment of the samples with a preservative is necessary prior to shipment to Teledyne Isotopes. I. Aquatic Biota - Algae No algae was collected for analysis during I992. Algae was not available in sufficient sample quantities during I992 to warrant collection and analysis. The Palisades Radiological Environmental Monitoring Program does not require alage to be collected, althouth it has been collected in the past when available. One (I) liter quantities of algae (if available) are prepared for shipment to Teledyne isotopes by treating each sample with IO ml of a IO% formaldehyde solution for preservation. J. Fi sh A total of 2I individual fish samples were collected from two (2) locations during two (2) separate sample collections in I992. Eleven (II) fish samples were obtained from Palisades (discharge) and.ten (IO) samples from the Ludington Control Station. Evaluation of the fish analytical results was based on a data means comparison between the Palisades and Ludington Control Samples as well as with the Palisades ODCM reporting limits. Of the isotopic analyses listed on Table HP I0.4-2, only gross beta activity was greater than LLD. No Palisades ODCM action levels or reporting levels were exceeded nor were any special analyses requested for I992.

As a minimum, at least two (2) different fish species (ie, forage, sport fish, etc) per designated location per year are collected. When caught, a one (1) liter quantity of fish sample is prepared

  • K.

for shipment to Teledyne Isotopes. Each sample is treated with 10 ml of a 10% formaldehyde solution for preservation. Broad Lead Vegetation No broad leaf vegetation samples were collected from the surrounding Palisades environs during 1992. The collection of broad leaf vegetation samples serves as a backup and/or alternative sampling media in case any milk sampling location(s) become(s) unavailable. There were no problems associated with the quantity or quality of milk samples for the 1992 reporting year. L. Non-Routine Samples None M. Gaseous and Liquid Radwaste Effluent Composite Samples Although not a direct reporting component in the Palisades Annual Radiological Environmental Monitoring Report, results of the gaseous and liquid monthly radwaste effluent composite samples are evaluated against overall environmental trending data. This evaluation is the basis for determining isotopic dispersion and deposition patterns within the surrounding environs of Palisades. All results are compared against Palisades ODCM radioactive effluent LLDs. All isotopic LLDs were met. Both the gaseous and liquid radwaste effluent composite samples are collected monthly and sent to Teledyne Isotopes for analysis. The liquid effluent composite sample is based on a specific ratioed volume amount of sample collected per total batch volume release. The gaseous radwaste effluent composite sample results are based on analyzing four (4) or five (5) weekly stack gas filters. No special sample treatment with a preservative is required prior to laboratory analysis. III. Assessment of Palisades Operation Environmental Impact In reviewing the 1992 Palisades radiological environmental monitoring data and comparing it to previous operational and pre-operational data, all trending parameters continue to indicate that the operation of Palisades has minimal environmental impact. Most isotopic activity is at environmental background levels. Since the Chinese stopped open atmospheric testing of nuclear devices in late 1981-82, environmental background radiation levels continue to decrease. The effect of the Chernobyl fallout (April 1986) on milk, aquatic biota and fish also appears to have had no lasting results. Evidence of an overall environmental isotopic buildup (attrjbutable to Plant effluents) remains negligible as well. In most instances, sample analytical results were below previously established environment background levels .

PALISADES 1.0 INfRODUCTION The following constitutes the final Monthly Progress Report for the Radiological Environmental Monitoring Program conducted at the Palisades Nuclear Generating Plant, Covert, Michigan. Results of completed analyses are presented in the attached tables. Data obtained in the program are well within the ranges previously encountered in the program and to be expected in the environmental media sampled. For all gamma isotopic analyses, the spectrum is computer scanned from 80 to 2048 KeV. Specifically included are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Ba-La-140, Cs-134, and Cs-137. Naturally occurring gamma-emitters, such as K-40 and Ra daughters, are frequently detected but not listed here. Data listed as"<" are at the 4.66 sigma level, others are 2 sigma. Unless noted otherwise, the less than value ("<") reported under "Other Gammas" is for Co-60 and may be higher or lower for other radionuclides. All concentrations, except gross beta, are decay corrected to the time of collection. All samples were collected within the scheduled period unless noted otherwise in the Listing of Missed Samples. 1

Appendix A Interlaborator:y Comparison Program Results Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated* in interlaboratory comparison (crosscheck) programs ~ince the formulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental-type samples (e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on the laboratory's analytical procedures and to alert it to any possible problems. Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used. The results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water, air filters, and food samples during the period January 1988 through December 1992. This program has been conducted by the U.S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada. I The results in Table A-2 were obtained for thermoluminescent dosimeters (TLDs) during the period 1976, 1977, 1979, 1980, 1984, and 1985-86 through participation in the Second, Third, Fourth, Fifth,, Seventh, and Eighth International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2. Also Teledyne testing results are listed. Table A-3 lists results of the analyses on in-house spiked samples. Table A-4 lists results of the analyses on in-house "blank" samples. Attachment B lists acceptance criteria for "spiked" samples. Addendum to Appendix A provides explanation for out-of-limit results. A- 2

ADDENDUM TO APPENDIX A The following is an explanation of the reasons why certain samples were outside the control limit specified by the Environmental Protection Agency for the Interlaboratory Comparions Program starting January 1988. EPA TIML Control Result. Limit Uib Code

  • Analysis (pCi/L)a (pCi/L)a Explanation STF-524 K 1010.7+/-158.5b 1123.5-1336.5b Error in transference of data. Correct data was 1105+/-33 mg/kg. Results in the past have been within the limits and TIML will monitor the situation in the future.

STW-532 1-131 9.0+/-2.0 6.2-8.8 Sample recounted after 12 days. The average result was 8.8+/-1.7 pCi/L (within EPA control limits). The sample was recounted in order to check the decay. Results h1 the past have been within the limits and TIML will continue to monitor the situation in the future. STW-534 Co-60 63.3+/-1.3 41.3-58.7 High level of Co-60 was du~ to contamination of beaker. Beaker was discarded upon discovery of contamination . and sample was recounted. Recount results *were 53.2+/-3.6 and 50.9+/-2.4 pCi/L STM-554 Sr-90 51.0+/-2.0 54.8-65.2 The cause of low result was due to very high fat content of milk. It should be noted that 63% of all 

                                                            *participants failed this test Also, the average for all participants was 54.0 pCi/L before the Grubb and 55.8 pCi/L after the Grubb.

STW-560 Pu-239 5~8+/-1.1 3.5-4.9 The cause of high results is not known though it is suspected that the standard was not properly calibrated by supplier and is under investigation. New Pu-236 standard was obtained and will be used for the next test. STW-568 Ra-228 26+/-1.0 2.7-4.5 The cause of low results is not known. Next EPA cross check results were within the control imits. No further action is planned. A-36

  • 30.3-47.7 The cause of low results was falsely high Sr-90 45.7+/-4.2 49.8-60.2 recovery due to suspected incomplete .

calcium removal. Since EPA sample was used up, internal spike was*; prepared and analyzed. The results were within control limits (See table A-3, sample QC-MI-24). No further action is planned. STW-589 Sr-90 17.3+/-1.2 17.4-22.6 Sample was reanalyzed in triplicate; results of reanalyses were 18.8+/-1.5 pCi/L. No further action is planned. STM-599 K 1300.0+/-69.2C 1414.7-1685.3c Sample was reanalyzed in triplicate. Results of reanalyses were 1421.7+/-95.3 mg/L. The cause of low results was using wrong volume. STW-601 Gr. alpha 11.0+/-2.0 11.6-324 Sample was reanalyzed in triplica Results of reanalyses were 13.4+/-1. pCi/L STAF-626 Gr. alpha 38.7+/-1.2 14.6-35.4 The cause of high results is the difference in geometery between standard used in the TIML lab and EPA filter. STW-632 Ba-133 74.0+/-6.9 51.6-72.4 Sample was :reanalyzed. Results of the reanalyseswere 63.8+/-6.9 pCi/L within EPA limit. STM-641 I-131 130.7+/-16.8 88.9-127.1 The cause of high result is unknown. In-house spike sample was prepared with activity of I-131 68.3+/-6.8 pCi/L Result of the analysis was 69.1+/-9.7 pCi/L STM-661 Sr-89 25.3+/-7.6 29.3-46.7 The cause of low result is unknown.* Data was checked for errors. The In-house. spike sample was prepared with activity of Sr-89 41.0+/-10.0 pCi/L Result of the analysis was 37.2+/-3. *, pCi/L .  ! A-37

Analysis (pCi/L)a (pCi/L)a Explanation STM-673 K 1540.0+/-103.9C 1597.3-1902.7 Activity was calculated using the wrong volume (3.5 L), instead of 3.25 L. Correction for volume resulted in a value of 1660.0+/-110.1 mg/L; within EPA control limits. a Reported in pCi/L unl~ otherwise noted. c Concentrations are reported in mg/L. A-38

APPENDIXB DATA REPORTING CONVENTIONS B-1

Data Reporting Conventions 1.0. All activities except gross alpha and gross beta are decay corrected to collection time or the end of the collection period. 2.0. Single Measurements Each single measurement is reported as follows: x+/-s where x =value of the measurement; s = 2a counting uncertainty (corresponding to the 95% confidence level). In cases where the activity is found to be below the lower limit of detection L it is reported as 

                        <L where L =the lower limit of detection based on 4.66a uncertainty for a background sample.

3.0. Duplicate analyses 3.1 Individual results: Xt +/-St Xt+/-s2 Reported result: x+/-s where x = (1/2) Cxt +/-xv 

                   *=(1/2)     F 3.2. Individual results:        <Lt
                                       <L2 ReJ>Orted result:         <L where L = lower of Lt and L2 3.3. Individual results:       x +/-s
                                       <L Reported result:         x+/-s if x~L;
                                       <L otherwise B-2

4.0. Corr:nputation of Averages and Standard Deviations 4.1 A'\verages and standard deviations listed in the tables are computed from awl of the individual measurements over the period averaged; for exxa.mple, an annual standard deviation would not be the average of q~uarterly standard deviations. The average x and standard deviation(s) ot:f a set of n ntllJ!bers x1, x2 ... Xn are defined as follows: 

                   -x=-1 'C"x n~*

S= 

                        .yr.{x-X)2 1

n-4.2 Values below the highest lower limit of detection are not included in thee average. 4.3 H aall of the values in the averaging group are less than the highest LLD, thee highest LLD is reported. 4.4 H :i:ill but one of the values are less them the highest LLD, the single valwe x and associated two sigma error is reported. 4.5 In m>unding off, the following rules are followed: 4.S.:l. H the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged. As an example, 11.443 is rounded off to 11.44.

  • 4.5.2 H the figure following those to be retained is greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example, 11.446 is rounded off to 11.45.

4.5.3.. H the figure following those to be retained is 5, and if there are no figures other than zeros beyond the five, the figure five is dropped, and the last-place figure retained is increased by one if it is an odd number or it is kept unchanged if an even number. As an example, 11.435 is rounded off to 11.44, while 11.425 is rounded off to 11.42 B-3
