SURVEILLANCE COMM ENTS AND OBSERVATIONS: This survey unit was accessible after the remov al of the CCDD pile. The FSS technician contac ted the MBI forema n (N. Friant) for suppor t, entered the survey unit to perform the walk down and select the sample locations. The MBI laborer support will join the FSS technic ian when they becom e available_ 14:55 The FSS technic ian receive d MBI laborer suppor t (Tim C) and setup at the first biased surface soil sample location. 15:00 Collec ted biased surface soil sample #Ll 12112AVJGS001SS.

Description:

light/medium brown sand, and gravel. Locati on was taken on the footprint of a small piece of metal that was remov ed from survey unit. The metal was survey ed, result, indistin guishable from background. 15:10 Collec ted biased surface soil sample #Lll21 12AVJ GS002 SS.

Description:

light/medium brown sand, and gravel. Locati on selecte d at tire marks and water mark area. 15:25 Compl eted surveillance survey. The group signed out of the survey unit. The collected samples were brough t to the sample prep trailer for processing. Notes: The sample locations were GPS'd, and the correct ed coordin ate with the locatio n will be shown on the attached map. There were some small pieces of plastic and metal, water bottles, and some old flags survey ed and remov ed from the survey unit. The postings were satisfactory. The postings are represe nted on the adjacent FSS survey units. A Model 3 #283273 with a 44-9/PR355602, cal due 1-24-20 was used for all the surveying. All survey results were indistin 'shable from back ound. Back ound 30-50 c m.

SURVEILLANCE COMMENTS AND OBSERVATIONS: This survey unit was part of the traverse path to remove the CCDD pile. The CCDD is now removed, and the surveillance survey is being performed. The FSS technician will perform the planned surveillance survey (walk down and sample), but will also include a gamma walk over survey on the traverse path. The laborer support will be available after lunch, so the FSS technician will be going in and perform the walk down and complete the gamma walk over survey. Informed the MBI foreman (N.Friant). 08: 15 The FSS technician signed in and surveyed all the sampling equipment into the survey unit. The FSS technician established the scan area and started with verifying the backgrounds. The west side has a higher background due the media having more clay surface, so there will be two set of backgrounds making two scan areas, #1 and #2. Scan Area #I backgrounds: 2103, 2117, 2208, 2284, and 2116 cpm, AVG 2166 cpm, MDCR 497 cpm, and ASP 2663 cpm. Scan Area #2backgrounds: 3003, 3526, 3590, 3572, and 3413 cpm, AVG 3421 cpm, MDCR 625 cpm, and ASP 4046 cpm. Completed the gamma walk over scan, lunch. 12:30 MBI laborer support (RD, AV) joined the FSS technician to complete this survey. The group signed/surveyed into the surve unit. 13:00 Collected biased surface soil sample #LI l2203BVJGS001SS.

Survey Unit Type: OpenLand!ZI Structure D System Classification: Class 3 D Class2 D Class 1 ~ Reason for Surveillance: Semi-Annual IZI Special D Surveillance Due Date: 7-10-19 Reason: Bi-annual Surveillance survey. (Survey Date surveillance performed: 8-1-19 performed after due date because the storage and removal of the CCDD pile in the adjacent survey area 12205). SURVEILLANCE ACTIVITIES:

1) Review ZS-LT-300-001-003 Attachment 2, FSS Area Access Request, Authorization and Sign-In Sheet for authorized entries into the FSS Survey Unit*--*-----------------------------------------------------------------------------------------* IZ!

2) Perform a walk down of the FSS Survey Unit and identify decommissioning activities adjacent survey units that could have a reasonable potential to spread radioactive material to the FSS Survey Unit--------*------- IZ!

SURVEILLANCE COMMENTS AND OBSERVATIONS: The CCDD is now removed, and the surveillance survey is being performed. The FSS technician and the MBI laborer (RD, AV) support walked down the survey unit and selected sample location. Informed the MBI foreman (N.Friant). 13:38 The FSS technician signed the group in, and surveyed all the sampling equipment into the survey unit. 13:52 Collected biased surface soil sample #Ll 12203CVJGS001SS.

Description:

medium brown sand, and gravel. Location selected at a dried, low water area. 14:15 Completed surveillance in this survey unit. The group signed out of the survey unit. The collected sample was brought to the sample prep trailer for processing. Notes: The sample location was GPS'd, and the corrected coordinate with the location will be shown on the attached map. There were some small pieces of metal, and old flags that were surveyed and removed from the survey unit. The postings were satisfactory. The postings are represented on the adjacent FSS survey units. A Model 3 #283228 with a 44-9/PR355606, cal due 1-12-20 was used for all the surveying.

Description:

Performing 1st Bi-Annual surveillance survey. Survey Unit Type: Open Land IZI Structure D System O Classification: Class 3 D Class 2 D Class 1 IZI Reason for Surveillance: Semi-Annual IZI Special D Surveillance Due Date: 7-10-19 Reason: Bi-annual Surveillance survey. (Survey Date surveillance performed: 8-1-19 performed after due date because the storage and removal of the CCDD pile in the adjacent survey area 12205). SURVEILLANCE ACTIVITIES:

1) Review ZS-LT-300-001-003 Attachment 2, FSS Area Access Request, Authorization and Sign-In Sheet for authorized entries into the FSS Survey Unit**************-**-**-***-**---****-****--*--*--*****----*-**-*---* --*--*---------*---------** 1::8'.1

2) Perform a walk down of the FSS Survey Unit and identify decommissioning activities adjacent survey units that could have a reasonable potential to spread radioactive material to the FSS Survey Unit.-*---*-**------* 1::8'.1 SURVEILLANCE COMMENTS AND OBSERVATIONS:

The CCDD is now removed, and the surveillance survey is being performed. The FSS technician and the MBI laborer (RD, AV) support walked down the survey unit and selected sample location. Informed the MBI foreman (N.Friant). 14: 15 The FSS technician signed the group in, and surveyed all the sampling equipment into the survey unit. 14:33 Collected biased surface soil sample #Ll 12203DVJGS001SS.

Description:

medium brown sand, and gravel. Location selected at dried, low point in soil. 14:45 Completed surveillance in this survey unit. The group signed out of the survey unit. The collected sample was brought to the sample prep trailer for processing. Notes: The sample location was GPS'd, and the corrected coordinate with the location will be shown on the attached map. There were some small pieces of metal, water bottle, plastic at fence line, and old flags that were surveyed and removed from the survey unit. The postings were satisfactory. The postings are represented on the adjacent FSS survey units. A Model 3 #283228 with a 44-9/PR355606, cal due 1-12-20 was used for all the surveying. All survey results were indistinguishable from background. Back ound 30-50 cpm. aren 1c o so :
