1.0 Introduction This Source Water Protection Plan (SPP) was prepared for the COB well system (WSID #20559) at Entergy Nuclear Northeast, Vermont Yankee in Vernon, Vermont. This system consists of one drilled bedrock well. The purpose of this SPP is to protect the water quality of this well by identifying and managing the potential sources of contamination and threatening activities that occur within the source protection area. This document has been prepared in accordance with the Vermont Water Supply Rule, Chapter 21, and follows the outline prepared in the publication entitled "Protecting Public Water Sources in Vermont"dated February 24, 1997.
The COB well is located on the southeast side of Vermont Yankee's property off of Governor Hunt Road in Vernon Vermont. (See Figures 1 &
2). According to the well completion report (WR # 214), the well was drilled in December 1984 by Morrison-Knudson Inc. The well is 362 feet deep and has 80 feet of steel casing. The well yield is 12 gallons per minute. Copies of the well completion reports are in Appendix A.
The source protection area (SPA) for the COB Well consists of a circular area within a 500-foot radius of the well (Figure 1). The SPA was determined to be 500-feet based on the maximum average daily demand for the well system, as listed in the Water Supply Division Guidance Document. The SPA consists of two "zones". Zone I consists of an isolation zone consisting of a circular area within a 200-foot radius around the well where impacts are likely to be immediate and certain. Zone 2 consists of the remaining areas of the SPA, and is considered the primary area of contribution to the well. In this area there will be probable impacts from potential sources of contamination.
2.0 Potential Sources of Contamination 2.1 Existing Land Uses and Potential Sources of Contamination The current land uses observed within the SPA consist of air conditioning units, office building, reactor and turbine buildings, chemical storage tanks, site access roads, transformers, a former UST site SMS #99-2617, fuel oil storage tanks, leachfields and industrial water storage tanks. There are railroad tracks within the SPA for this well. These paved railroad tracks are infrequently used and require no herbicide treatment. Vermont Yankee owns all of the land within the zones of the COB system well. See Figure
- 2.
2.2 Potential Sources of Contamination An inventory of the potential sources of contamination (PSOC) is presented in Table 1. The locations of these PSOCs are presented on Figure 2. Due to the scale of the map, in cases where more than one PSOC exists on a parcel they will be grouped under one designation.

- Refer to Section 3.0 for an Explanation of Contamination Item #6.
3.0 Assessment of Threats Air Conditioning Unlts-(Contamination ID #1)
The air conditioning units are well maintained per the plant preventive maintenance program. Due to this and the depth of the well the risk associated with these is considered to be low, but In accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
Office Buildinq, Reactor and Turbine Buildincis-(Contamination ID #2,3)
Due to the chemical control and hazardous waste programs which control chemical storage and disposal these structures and the activities occurring
within them are not considered a significant risk to the well, but in accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
Chemical Storage Tanks-(Contamination I D #4):
Chemical tanks at the intake structure are bermed tanks downgradient of the drinking water well and pose a low risk for contamination. There also exits a bermed liquid nitrogen tank, which is on the same gradient as the drinking water well. This tank also poses a low risk for well contamination.
However, in accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
Site Access Roads & Railroad Tracks-(Contamination ID #5)
There are plant maintained roads and railroad tracks within the 200-foot radius zone I areas of the COB well. The paved railroad tracks are infrequently used and require no herbicide treatment. The roadways are considered a potential source of contamination due to the application of road salt, which could cause elevated levels of sodium 7nd chloride in the well. In addition, there is also a potential for a spill or leaks of petroleum products from vehicles in the parking areas or as they transverse the roadways. Due to an extensive storm drain system the threat to the well Is deemed to be low risk. However, the road salt, which is typically mixed with sand prior to application represents a moderate risk to the wells, this again is due to depth of the well being 362 feet deep, but in accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
Transformer-(Contamination ID #6)
There are currently two spare transformers stored on-site. The GE transformer is located on a concrete pad north of the main septic system
.(see figure #2). The Peebles transformer is located north of the PSB building. All transformers on site have non-PCB dielectric fluid. Neither are staged within the proximity of this well.
SMS Site #99-2617-(Contamination ID #7)
Vermont Yankee SMS Site 99-2617 contains petroleum by-products and chlorinated solvents, (tetrachlorodthene [PCE] and its breakdown products). Aggressive groundwater remediation is not being performed on these wells due to the concentrations of contaminants being at a low level.
Thus this site poses a low risk to the drinking water wells due to the low
levels of contaminants, being downgradient from the wells and the depth of the drinking water wells.
Fuel Oil Tanks-(Contamination ID #8)
All fuel oil tanks on site have a double walled construction; with leak and overfill protection systems. Therefore these are characterized as low risk to the water supplies.
On-Site Septic Systems-(Contamination ID #9):
Septic systems represent potential sources of nitrates, chlorides, other Inorganic compounds, bacteria, viruses and radionuclide contamination.
In addition, if improperly used, such as for the disposal of paints, solvents, petroleum products and other hazardous wastes, they could also be a source of organic compounds as well. At Vermont Yankee the chemical control and hazardous waste programs prohibits the disposal of chemical in a manner Inconsistent with the manufacturers Material Safety Data Sheet (MSDS).
The wells at Vermont Yankee are topographically upgradient from the septic systems. The well depths are also very deep in the groundwater table. Groundwater flow Is in the direction of the river. Therefore this is considered as a low risk to contaminate the water supplies, but in accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
Industrial Water Storage Tanks-(Contamination ID #10):
Plant industrial water storage tanks are bermed tanks that are adequately maintained. These pose a low risk for contamination, but in accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
4.0 Management of Risk In order to reduce the potential risk of contamination to the drinking water supply wells at Vermont Yankee, Vermont Yankee will perform an annual inspection of the SPA to confirm that the company is following the best management practices and identify any changes in and uses or property owners. Once every three years updates indicating any changes in land
uses/PSOC's will be submitted to the Water Supply Division. The updates may simply consist of a letter, which describes any changes to the original SPP, or a letter stating there have been no changes.
5.0 Contingency Plan This contingency plan outlines the steps that may be taken by Vermont Yankee in the event a well becomes contaminated, or there is a significant reduction in yield, or if there are mechanical problems.
5.1 Emergency Response If an emergency exists such as a spill or other contamination event occurs within the SPA, or if a regulated compound is found above the acceptable levels during a routine sampling event, Vermont Yankee may notify the following people/agencies:

1.0 Introduction This updated Source Water Protection Plan (SPP) was prepared for the Main well system (WSID #8332) at Entergy Nuclear Northeast, Vermont Yankee in Vernon, Vermont. This system consists of two drilled bedrock wells the West well and the Southwest well. The purpose of this SPP is to protect the water quality of these wells by identifying and managing the potential sources of contamination and threatening activities that may occur within the source protection area. This document has been prepared in accordance with the Vermont Water Supply Rule, Chapter 21, and follows the outline prepared in the publication entitled "Protecting Public Water Sources in Vermont" dated February 24, 1997.
The Main southwest well is located on the southwest side of Vermont Yankee's property off of Governor Hunt Road in Vernon Vermont. (See Figures I & 2). According to the well completion report (WR # 253), the well was drilled in June 1986 by Green Mountain Well Company Inc. The well Is 500 feet deep and has 67 feet of steel casing. The well yield is 10.5 gallons per minute. The Main west well is located on the west side of Vermont Yankee's property off of Governor Hunt Road in Vernon, Vermont. (See Figures 1 & 2). According to the well completion report (WR # 283), the well was drilled in July 1987 by Green Mountain Well Company Inc. The well is 555 feet deep and has 50.1 feet of steel casing. The well yield is 73.7 gallons per minute. Copies of the well completion reports are included in Appendix A.
The source protection area (SPA) for the southwest and west wells consists of a circular area within a 500-foot radius of each well (Figure 1).
The SPA was determined to be 500-feet based on the maximum average.
daily demand for the well system, as listed in the Water Supply Division Guidance Document. The SPA consists of two "zones". Zone I is consists of an isolation zone consisting of a circular area within a 200-foot radius around the well where Impacts are likely to be immediate and certain. Zone 2.consists of the remaining areas of the SPA, and is considered the primary area of contribution to the well. In this area there will be probable impacts from potential sources of contamination.
2.0 Potential Sources of Contamination 2.1 Existing Land Uses and Potential Sources of Contamination The current land uses observed within the SPA consist of fields,..
office buildings, warehouse, parking lots, fences, roads, railroad tracks, switchyards, a former UST site SMS #99-2617, fuel oil storage tanks and leachfields. Vermont Yankee owns all of the land within the zones of the Main system wells. See Figure #2.
2.2 Potential Sources of Contamination An inventory of the potential sources of contamination (PSOC) is presented in Table 1. The locations of these PSOCs are presented on Figure 2. Due to the scale of the map, in cases where more than one PSOC exists on a parcel they will be grouped under one designation.

3.0 Assessment of Threats Fields/Fence-(Contamination ID #1)
The fields, which are closest to the West well, are on Vermont Yankee property. Along the field edge is a security fence. Roundup, a systemic
weed killer, was historically applied to the fence line area. This activity has been replaced by weed whacking Inside the SPA. The activities occurring in the field and along the fence around the west well are considered low risk activities, but in accordance with the Vermont Water Supply Rule, Section 16, these are considered a high risk due to their..
importance and potential.
Office Building and Warehouse-(Contamination ID #2,3)
Due to the chemical control and hazardous waste programs which control chemical storage and disposal these structures and the activities occurring within them are not considered a significant risk to the well, but in accordance with the Vermont Water Supply Rule, Section 16, these are considered a high risk due to their importance and potential.
Parking Lots, Site Access Roads and Railroad Tracks-(Contamination ID
- 4.5)
There are plant maintained roads and parking areas within the 200-foot radius zone I areas of both the West well and the Southwest well. The road and parking areas are considered a potential source of contamination due to the application of road salt, which could cause elevated levels of sodium and chloride in the well. In addition, there is also a potential for a spill or leaks of petroleum products from vehicles in the parking areas or as the vehicles transverse the roadways. Due to an extensive storm drain system the threat to the wells is believed to be low risk. However, the road salt which is typically mixed with sand prior to application represents a moderate risk to the wells. This is due to a result of the depth of the well being 400 to 500 feet deep. There are railroad tracks in this area and they are rarely used. Maintenance of vegetation within these tracks, in the SPA's, is via weed whacking. In accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
345 kV Switchyard-(Contamination ID #6)
The switchyard has a separate storm drain system and outfall area therefore activities in this area would not cause contamination into the plant wells. In adcordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential. Additionally, the switchyard Is downgradient from the well. See Figure 4.
SMS Site #99-2617-(Contamination I D #7)
Vermont Yankee SMS Site 99-2617 contains petroleum by-products and chlorinated solvents, (tetrachloroethene [PCE] and its breakdown products). Aggressive groundwater remediation Is not being performed on
these wells due to the concentrations of contaminants being at a low level.
Thus this site poses a low risk to the drinking water wells due to the low levels of contaminants, being downgradient from the wells, and the depth of the drinking water wells.
Fuel Oil Tanks-(Contamination ID #8)
All fuel oil tanks on site have eithef a double walled construction, with leak and overfill protection systems or are surrounded by secondary containment structures. Therefore these are characterized as low risk to the water supplies.
On-Site Septic Systems-(Contamination ID #9):
Septic systems represent potential sources of nitrates, chlorides, other inorganic compounds, bacteria, viruses and radlonuclide contamination.
in addition, If Improperly used, such as for the disposal of paints, solvents, petroleum products and other hazardous wastes, they could also be a source of organic compounds as well. At Vermont Yankee the chemical control and hazardous waste programs prohibits the disposal of chemical in a manner inconsistent with the manufacturers Material Safety Data Sheet (MSDS).
The wells at Vermont Yankee are topographically upgradient from the septic systems. The well depths are also very deep in the groundwater table. Groundwater flow is in the direction of the river. Therefore this is considered as a low risk toward contaminate contamination of the water supplies, but in accordance with the Vermont Water Supply Rule, Section 16 these units are considered a high risk due to the importance and potential.
"Transformers-(Contamination ID #10):
There are currently two spare transformers stored on site. One (identified as #1 in Table 1), manufactured by General Electric, Is located north of the Main septic system (see figure 2). The second (identified as #2 in Table 1), manufactured by Peebles of the United Kingdom, is located north of the NEOB buildirig, near the west well. Two additional transformers Were recently replaced during the Station's required cooling tower upgrades.
These two transformers will be stored temporarily in a full containment berm near the cooling towers and down gradient of all drinking water wells. The oil contained In the transformers is all PCB free transformers is all pcb-free. Each transformer either contains a vault where any oils released would be captured or are stored within a containment structure capable of holding the entire contents of the transformers. Thus, these are considered to be a medium to low risk relative to contaminating the
Main water supply. Plans are being developed to remove the Peebles transformer (#2) from on-site in the near future. Spill prevention control and countermeasure plans are currently being updated for both transformers so they will continue to comply with updates to the federal regulations (40CFR1 12.7)...
Industrial Water Storagqe Tanks-(Contamination ID #11):
Plant industrial water storage tanks are bermed tanks downgradient of the drinking water well and pose a low risk for contamination.
4.0 Management of Risk In order to reduce the potential risk of contamination to the drinking water supply wells at Vermont Yankee, Vermont Yankee will perform an annual inspection of the SPA to confirm that the company is following the best management practices and to identify any changes in and use or property owners. Once every three years updates indicating any changes in land use/PSOC's will be submitted to the Water Supply Divis~on. The updates may simply consist of a letter, which describes any changes to the original SPP, or a letter stating that there have been no changes.
5.0 Contingency Plan This contingency plan outlines the steps that may be taken by Vermont Yankee in the event a well becomes contaminated, or there is a significant reduction in yield, or if there are mechanical problems.

1.0 Introduction This Source Water Protection Plan (SPP) was prepared for the NEOB well system (WSID #20738) at Entergy Nuclear Northeast, Vermont Yankee-In Vernon, Vermont. This system consists of one drilled bedrock well. The purpose of this SPP is to protect the water quality of this well by identifying and managing the potential sources of contamination and threatening activities that occur within the source protection area. This document has been prepared in accordance with the Vermont Water Supply Rule, Chapter 21, and follows the outline prepared in the publication entitled "Protecting Public Water Sources in Vermont" dated February 24, 1997.
The NEOB well is located on the west side of Vermont Yankee's property off of Governor Hunt Road in Vernon Vermont. (See Figures 1 & 2).
According to the well completion report (WR # 6642), the well was drilled in July 1998 by Green Mountain Well Company Inc. The well is 500 feet deep and has 38 feet of steel casing. The well yield is 30 gallons per minute. Copies of the well completion reports are in Appendix A.
The source protection area (SPA) for the COB well consists of a circular area within a 500-foot radius of the well (Figure 1). The SPA was determined to be 500-feet based on the maximum average daily demand for the well system, as listed in the Water Supply Division Guidance Document. The SPA consists of two "zones". Zone I consists of an Isolation zone consisting of a circular area within a 200-foot radius around the well where impacts are likely to be immediate and certain. Zone 2 consists of the remaining areas of the SPA, and is considered the primary area of contribution to the well. In this area there will be probable impacts from potential sources of contamination.
2.0 Potential Sources of Contamination 2.1 Existing Land Uses and Potential Sources of Contamination (SPOC)
The current land uses observed within the SPA consist of fields, office buildings, parking lots, roads, railroad tracks, switchyards, fuel oil storage tank and leachfields. Vermont Yankee owns all of the land within the zones of the NEOB system well.
2.2 Potential Sources of Contamination An inventory of the potential sources of contamination (PSOC) is presented in Table 1. The locations of these PSOCs are presented on Figure 2. Due to the scale of the map, in cases where more than one PSOC exists on a parcel they will be grouped under one designation.

3.0 Assessment of Threats Fields/Fence-(Contamination ID #1)
The fields, closest to the West well, are on Vermont Yankee property.
Along the field edge is a security fence. Roundup, a systemic weed killer, was historically applied to the fence line area. It has been replaced by weed whacking within the SPA. The activities regarding field and fence around the well is considered a low risk activity, but In accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
Office Buildina -(Contamination ID #2)
Due to the chemical control and hazardous waste programs which control chemical storage and disposal these structures and the activities occurring within them are not considered a significant risk to the well, but in accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
Parking Lots, Site Access Roads and Railroad Tracks - (Contamination ID
- 3.4)
There are plant maintained roads and parking areas within the 200-foot radius zone 1 areas of both the NEOB well. The road and parking areas are considered a potential source of contamination due to the application of road salt, which could cause elevated levels of sodium and chloride in the well. In addition, there Is also a potential for a spill or leaks of petroleum products from vehicles in the parking areas or as they transverse the roadways. Due to an extensive storm drain system the threat to the wells is believed to be low risk. However, the road salt which is typically mixed with sand prior to application represents a moderate risk to the wells. There are railroad tracks in the vicinity of this well but they are rarely used. Maintenance of vegetation along the tracks within the SPA's Is via weed whacking. In accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
345 kV Switchyard- (Contamination ID #5)
The switchyard has a separate storm drain system and outfall area therefore activities in this area would not cause contamination into the plant wells. Additionally, the switchyard is downgradient from the well.
See Figure 4.
Fuel Oil Tanks- (Contamination ID #6)
All fuel oil tanks on site have a either double walled construction, with leak and overfill protection systems or are surrounded by a full containment structure. Therefore these are characterized as low risk to the water' supplies.
On-Site Septic Systems- (Contamination ID #7):
Septic systems represent potential sources of nitrates, chlorides, other inorganic compounds, bacteria, viruses and radionuclide contamination.
In addition, if Improperly used, such as for the disposal of paints, solvents, petroleum products and other hazardous wastes, they could also be a
source of organic compounds as well. At Vermont Yankee the chemical control and hazardous waste programs prohibits the disposal of chemical in a manner inconsistent with the manufacturers Material Safety Data Sheet (MSDS).
The wells at Vermont Yankee are topographically upgradient from the septic systems. The well depths are also very deep in the groundwater table. Groundwater flow Is In the direction of the river. Therefore this is considered as a low risk to contaminate the water supplies, but in accordance with the Vermont Water Supply Rule, Section 16 these are considered a high risk due to the importance and potential.
Transformers- (Contamination ID #8):
There are currently two spare transformers stored on-site. The Peebles transformer is currently stored north of the PSB building. The GE transformer is located north of the Main septic system (see figure #2).
The oil contained In the transformer is all pcb-free. The Peebles transformer has approved spill prevention control and countermeasures in place in fulfillment of the 40CFRl12 requirement. It is considered to be a low risk to contaminate the water supply, but in accordaflce with the Vermont Water Supply Rule, Section 16 it is considered a high risk due to the importance and potential.
Residential Land Formally Owned by Ms. Thomas (Contamination ID #9):
The Thomas house was purchased, by Entergy Nuclear Northeast, from Ms. Thomas in 2002. It has a #2 fuel oil tank and is equipped with an on-site septic system. Septic systems can serve as potential subsurface pathways of contaminant migration. Contaminant migration via groundwater in the area is not considered to pose a risk to the NEOB well based on the residential land usage and the presence'of septic systems well above the groundwater table combined with the depth of the well being 500 feet. This is considered low risk to contaminate the water supply.
4.0 Management of'Risk In order to reduce the potential risk of contamination to the drinking water supply wells at Vermont Yankee, Vermont Yankee will perform an annual inspection of the SPA to confirm that the company is following the best management practices and to identify any changes in use or property owners. Once every three years updates indicating any changes In land use/PSOC's will be submitted to the Water Supply Division. The updates
may simply consist of a letter, which describes any changes to the original SPP, or a letter stating that there have been no changes.
5.0 Contingency Plan This contingency plan outlines the steps that may be taken by Vermont Yankee in the event a well becomes contaminated, or there is a significant reduction in yield, or if there are mechanical problems.
5.1 Emergency Response If an emergency exists such as a spill or other contamination event occurs within the SPA, or If a regulated compound is found above the acceptable levels during a routine sampling event, Vermont Yankee may notify the following people agencies.
