ENCLOSURE 2 CORRECTIONS TO THE 2012 AREOR 1 page to Follow

L-MT-16-035 Page 1 of 1 Broadleaf vegetation samples were not collected since 2011 due to unavailability; these samples were not included as missed samples, because they were considered to be above and beyond required samples. Since they were included in the Offsite Dose Calculation Manual (ODCM) ODCM-07.01 Table 1, they were required samples for Monticello Nuclear Generating Plant and should have been included as missed samples. The affected pages have been included in their entirety (Attachment 1) and should replace existing pages (5 and 17), ML13135A006.

The complete data tables were to be submitted as part of the report; however, this data was not included with the annual reports prior to 2013. Attachment 2 will be added to the back of the annual report as submitted; this this will be an addition to the report and will not be replacing any pages in the report.

3.3 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.
