1.0 INTRODUCTION

1.1 Background

Yellow Jacket Drilling Services, LLC (Y JD) has been contracted to perform a total of twenty six (26) well abandonments by Los Alamos National Security (LANS) Environmental management (EM) Directorate. Four (4) wells have been designated as MT Test Wells, twenty one wells (21) Water Balance Wells and one (1) hole designated 50-603060. All wells are located within Los Alamos National Laboratory (LANL), Mortandad Canyon, located in Los Alamos County, New Mexico. Hole 50-603360 is located on the mesa top south of Pajarito Rd, in Technical Area 50.

The wells designated MCWB 4 thru 9b are constructed of 3 inch Sch 40 PVC up to depths of 80 feet bgs. (drilled in 1994); wells designated MT 1 thru 4 are constructed of 2 inch Sch 40 PVC up to depths of 75 feet bgs. (drilled in 1998); and hole designated 50-603060 (drilled in February 2008) are to be plugged and abandoned. This work will be performed under the statement of work (SOW) provided by RFP 1578464, dated February 26, 2016, LANS and the Work Plans for the Plugging & Abandonment of wells for Fiscal year 2016, LA-UR-16-2024, EP2015-0212, January 2016.

In general, twenty five (25) environmental monitor wells will be decommissioned by the following process; all pumps and down hole equipment will be removed, any water present will be removed and contained, well video (as required), followed by water sample collection (as required) 24 hours later, wells will be grouted in place by tremie pumping materials, followed by over drilling of the upper 20 feet of PVC well casing and cementing in the upper 20 feet of hole. After all well plugging actives are completed any above ground well features shall be removed as required. Upon completion of all decommissioning activities a monument shall be placed and surveyed.

YJD shall provide means and oversight for investigation derived waste (IDW) containment and on site management, Office of the State Engineer of New Mexico (NMOSE) plugging and abandonment documentation and required State submittals, and all required documentation set forth by the SOW.

This Field Implementation Plan (FIP) provides guidance for well servicing (including pump removal, water bailing & collection, video, etc.), well plugging & abandonment (in-place grouting & over drilling of upper 20 feet of PVC casing). and surface completion removals . Project staff, health and safety, waste management, security, schedules, and required permits are also discussed in this document.

1.2 Objectives

As stated in the Work Plans for the Plugging & Abandonment of wells for Fiscal year 2016, LA­UR-16-2024, EP2015-0212, January 2016, the purpose of the FIP= is to address activities required to complete the general scope of work that will establish a provision of the technical functions and expertise required for the effective and timely delivery of professional services to plug and abandon wells and boreholes for project. These services shall be in accordance with the NMOSE and Compliance Order on Consent.

The purpose for the SOW is for plugging and abandonment of wells to prevent the migration of surface water and potential contaminants within the wells to depth. A Waste Characterization Strategy Form (WCSF) has been prepared and a final Summary Report will be prepared for LANL.

FIP for Well Plugging and Abandonment Mortandad Canyon

3.0 FIELD ACTIVITIES

Field activities, including well servicing (including pump removal, water bailing & collection, video, etc.), well plugging & abandonment (in-place grouting and over drilling of upper 20 feet of PVC casing), and surface completion removal will follow an approved Integrated Work Document (IWD). The Work Plans for the Plugging & Abandonment of wells for Fiscal year 2016, LA-UR-16-2024, EP2015-0212, January 2016 will be used to guide field operations and ensure all objectives are met.

Field activities shall commence and attempt to follow the attached "projected work schedule", this schedule serves as outline for Y JD's intended performance timeline for the SOW. Y JD shall make all attempts practical and reasonable to maintain the schedule set forth in order to maintain the contract schedule set for by LANL. Y JD will keep LANL informed to their progress and maintain an updated weekly, project schedule.

A current Subcontractor Schedule for this project is presented in Figure 1.

3.1 Well Servicing and Well Preparation

Pump Rig, Drilling Rig and other associated equipment and supplies for the completion of the project will be staged around the work site in an organized and secure manner. Surplus and/or inactive equipment and supplies may be stored at the LANL project laydown yard (this area is to be determined by LANS). The STR, FTL, and drilling foreman will control the gate key.

3.1.1 Mobilization

Mobilization will consist of multiple events transporting and setting up equipment at the project location. Mobilization will include the following:

• Mobilize pump and drill rig, trailers (if necessary), support vehicles, abandonment tools and materials, and related ancillary supplies and equipment to the drill site.

• Stage alternative rigs, equipment, tools and materials at the laydown yard.

• Entrance/exit radiological screening of all equipment and tooling by RP-1. Perform all on site safety training, inspection of equipment and tooling prior to commencing work.

• Set up drill rig , trailers, support vehicles and tools at the designated location.

• Review scope of work and project-specific health and safety issues with crew.

• Complete all required training for all personnel.

• Obtain Facility Operations Director (FOO) Work Authorization, including rig inspection and IWD review.

The site will be accessed from south of Pajarito Rd. The water source for the project has been identified as a fire hydrant near the Pajarito yard on E. Pajarito Rd.

3.1 .2 Pump and Downhole Supplies Removal

Prior to the plugging and abandonment, all wells shall have all pumps, transducers, sounding tubes and other downhole equipment and tooling removed. A standard small capacity pump rig

3 April 2016

F/P for Well Plugging and Abandonment Mortandad Canyon

shall be utilized to remove all downhole equipment at twenty three (23) of the locations. The two remaining wells shall have this service performed by the drill rig due to location and access.

All materials and equipment removed shall be staged at a designated location for LANL or disposed of as part of the WCSF. IDW accumulated during pump removal activities will be staged on site and characterized as determined by the WCSF.

The Work Plans for the Plugging & Abandonment of wells for Fiscal year 2016, LA-UR-16-2024, EP2015-0212, January 2016 will be used to guide field operations and ensure all objectives are met.

3.1.3 Groundwater Removal, Recharge and Sampling

After all downhole equipment has been removed, the well will be checked for the presence of groundwater and the static (alluvial) water level (SWL) will be measured if present. Wells that have water present shall be bailed dry (or as close to practical) and shall be allowed to recharge for up to 24 hours. After the 24 hour period if water is present, a sample shall be collected by bailer and procured for analysis. All samples will be submitted to LAN L's Sample Management Office (SMO) with the corresponding chain of custody and any other required documentation. IDW accumulated during these activities will be staged on site and characterized as determined by the WCSF.

3.1.4 Well Video Logging

Some of the wells and bore hole may be video logged by a portable downhole camera by LANL prior to Y JD's arrival at LANL. While providing a vertical view and depth counter, the well shall be videoed and recorded to a Scan Disk. A copy of any wells' recording shall be made available upon request. This video will ensure no obstructions are present prior to the plugging and abandonment procedure.

3.1.5 Well Monument Survey

All well monuments shall be surveyed and data shall be provided to LANL in the final summary report. A global positioning system (GPS) hand held unit shall be utilized for determination of each well's northing, easting and elevation data. Coordinates shall be provided with respect to the North American Datum (NAD83).

3.2 Well Plugging and Abandonment

Upon completion of activities outlined in section 3.1 , the plugging and abandonment of twenty five (25) wells shall be performed in accordance with the NMOSE approved plugging and abandonment plans for each well . In addition, all work will follow The Work Plans for the Plugging & Abandonment of wells for Fiscal year 2016, LA-UR-16-2024, EP2015-0212, January 2016 as a guide field operations and ensure all objectives are met. A standard truck mounted hollow stem auger rig shall be utilized for the abandonment procedures. This will include tremie pumping materials from the bottom of the well up to the surface to ensure displacement of any water and provide a complete seal without any voids. After well has been grouted in place, over drilling of the upper twenty (20) feet of PVC casing shall performed, then a seal shall be placed within the over drilled borehole to complete sealing of the abandoned well. Should any settlement of grouting materials take place, the wells will be "topped off' the following day to ensure complete sealing prior to commencing with surface completion removal and restorations.

4 April 2016
