53.3 Program Execution The Program was executed as described in the preceding section with the following exceptions:
(1) Air Particulates / Air Iodine:
No air particulate / air iodine sample was available from location M-01 for the week ending June 29, 2011. There was no power, due to an open fuse.
 
No air particulate/air iodine sample was available from location M-03 for the week ending September 14, 2011. Run-time was significantly lower than expected. 
(2) Thermoluminescent Dosimeters:
 
The TLD for location M-05S was missing in the field for the third quarter, 2011.
The TLD for location M-1B was missing in the field for the fourth quarter, 2011.
 
(3) Surface Water:
 
Surface water was not collected at location M-08 during the months of January and February, 2011, due to unsafe ice conditions. The June 14, 2011 sample for composite was damaged in transit.
 
(4) Well Water:
 
Well water was not collected at location MW-1 in January, 2011. The January, 2011 sample collected from MW-12A sample was damaged in transit.
Well water from location MW-13A, October 17, 2011, was damaged in transit.
 
  (5) Milk
 
Milk was not available from locations M-16 and M-17 for January and February, 2011 collections. No milk was available from location M-17 after November 9, 2011. 
 
(6) Invertebrates
 
Bottom organisms were not collected in the Spring of 2011, due to high river levels. Bottom organisms could not be collected from control location M-8 in the Fall of 2011, due to high river levels. 
 
(7) Broad Leaf Vegetables Broad Leaf Vegetables were not collected in 2011 due to unavailability. The previous Critical Garden ceased to be used and attempts to obtain a sample from the new Critical Garden were unsuccessful.
Deviations from the program are summarized in Table 5.3.
3.4 Laboratory Procedures The iodine-131 analyses in milk and drinking water were made using a sensitive radiochemical procedure which involves separation of the iodine using an ion-exchange method and solvent extraction and subsequent beta counting.
 
Gamma-spectroscopic analyses are performed using high-purity germanium (HPGe) detectors.
Levels of iodine-131 in cabbage and natural vegetation and concentrations of airborne iodine-131 in charcoal samples were determined by gamma spectroscopy.

53.3 Program Execution The Program was executed as described in the preceding section with the following exceptions:
(1) Air Particulates / Air Iodine:
M-02. Volume for the week ending January 4, 2012 was lower than expected. A short power outage is suspected.
No air particulate sample was collected for the week ending June 27, 2012, the filter was misaligned in the holder. M-03. No air particulate / air iodine sample was available for the week ending May 9, 2012, the timer reading was low due to power interruption.
No air particulate sample was collected for the week ending June 27, 2012, the filter was misaligned in the holder.
No air particulate / air iodine sample was available for the week ending July 18, 2012, low volume due to power interruption. M-04. No air particulate / air iodine sample was available for the week ending May 30, 2012, the timer reading was low due to power interruption. M-05. No air particulate / air iodine sample was available for the week ending May 30, 2012, the volume was low due to power interruption. 
(2) Thermoluminescent Dosimeters:
 
The TLD for location M-01B was missing in the field for the first quarter, 2012.
The TLD for location M-08A was missing in the field for the first quarter, 2012.
The TLD for location M-11A was missing in the field for the fourth quarter, 2012.
 
(3) Surface Water:
 
Surface water was not collected at location M-08 for the weeks ending January 25 through February 15, 2012. The water was not collected due to unsafe ice conditions.
Both the January and February monthly composite samples were made up from available collections. 
 
(4) Well Water:
 
Well water was not collected at location MW-27 in January, 2012. The outside well was locked and the residence was vacant.
 
  (5) Milk
 
Milk was not available from locations M-16 and M-17 for the January through March, 2012 collections. No milk was available after November 7, 2012. 
 
(6) Invertebrates
 
Bottom organisms were not collected in the Spring of 2012, due to high river levels. 
(7) Shoreline Sediments
 
Shoreline sediment was not collected in the Spring of 2012, due to high river levels. 
 
(8) Broad Leaf Vegetable  Broad Leaf Vegetables were not collected in 2012 due to unavailability. The previous Critical Garden ceased to be used and attempts to obtain a sample from the new Critical Garden were unsuccessful. Deviations from the program are summarized in Table 5.3.

The following constitutes the final 2012 report for the Environmental Radiological Monitoring Program conducted at the Monticello Nuclear Generating Plant in Monticello, Minnesota.
Results of completed analyses are presented in the attached tables. 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 of Missed Samples. iv v 2.0.      LISTING of MISSED SAMPLESAll required samples were collected and analyzed as scheduled with the following exceptions:Collection Reason for not SampleAnalysisLocation (s)Date or conducting REMPPlans for Preventing TypePeriodas requiredRecurrenceAP/AIBeta, I-131M-2  1/4/2012Low sample volume.
