FEDEX: 779308184258 June 6, 2017 Mr. Christopher Ralston Maryland Department of the Environment Remediation Division, Oil Control Program 1800 Washington Blvd., Suite 620 Baltimore, Maryland 21230 RE: Near Northeast Optimization Work Plan Inactive Exxon Facility #28077 14258 Jarrettsville Pike Phoenix, Baltimore County, Maryland MDE Case # 2006-0303-BA2 Dear Mr. Ralston:

Kleinfelder, on behalf of Exxon Mobil Corporation (ExxonMobil) herein proposes groundwater

recovery optimization activities on 3501 Hampshire Glen Court and 14301 Jarrettsville Pike. The

optimization involves groundwater recovery in two areas of the Near Northeast (Figure 1):

1. 3501 Hampshire Glen Court: initiation of groundwater recovery from monitoring well

MW-168, and the lowering of existing pumps in MW-178C and MW-183, with the

objective of enhancing hydraulic gradient towards 3501 Hampshire Glen Court, and

evaluating whether hydraulic influence from these recovery well extends to MW-138D,

located at 3506 Hampshire Glen Court.

2. 14301 Jarrettsville Pike: recovery optimization by removing the existing pump from

MW-181B and deploying it in MW-181A, with the objective of recovering dissolved

hydrocarbon mass from the shallow zone.

Details of the proposed optimization activities are provided below.

3501 Hampshire Glen Court

Monitoring well MW-138D was installed on 3506 Hampshire Glen Court in August 2013 to a total

depth of 404 feet below grade (fbg) with 60 feet of 6-inch diameter steel casing and an open

borehole from 60-404 fbg. The well is fitted with a FLUTe™ liner for discrete-depth interval

sampling and to prevent vertical migration within the borehole. Since installation, elevated

concentrations of dissolved-phase hydrocarbons (>100 µg/L methyl tert butyl ether [MtBE]) have

been consistently observed in three sampling intervals – 95-100 fbg, 120-125 fbg, and 151-156

fbg (Table 1). Enhanced recovery is being proposed in three wells on 3501 Hampshire Glen

Court to direct hydraulic gradient away from and upgradient of monitoring well MW-138D and

preemptively entrain and recover dissolved-phase hydrocarbon concentrations to reduce flux

towards MW-138D.

Enhanced Recovery – Initiate Pumping from MW-168, Lowering Pumps in MW-178C and MW-

183

Monitoring well MW-168, located on 3501 Hampshire Glen Court, was installed in March 2009 to

a total depth of 250 fbg, with 65 feet of 6-inch diameter steel casing and an open hole from 65-

250 fbg. A top-loading pneumatic pump is proposed for installation in MW-168 at an initial depth

of 125-150 feet below top of casing (ft-toc), with the potential to lower further if warranted. The

MW-168 proposed pump depth is similar to the pump depth in MW-91C which has been highly

effective in reducing dissolved phase concentrations in the central portion of the 3501 Hampshire

Glen property. MW-168 has served its purpose as a monitoring well for characterizing the nature,

extent, and response to remediation of relatively deeper groundwater conditions at the 3501

Hampshire Glen Court property (Figure 1). Recent results from MW-168 indicate favorable

remediation progress at the downgradient edge of the property (Table 1). MW-168 is also the

closest monitoring well that intercepts the deeper migration pathway to MW-138D, which has

exhibited recalcitrant concentrations at depth. For these reasons, groundwater extraction will be

initiated from MW-168 to enhance hydraulic gradient away from and upgradient of monitoring well

MW-138D and preemptively entrain and recover dissolved-phase groundwater impacts before

MW-138D. The MW-168 groundwater recovery will be connected to existing subsurface HDPE

remediation piping via temporary above-ground piping terminating in the vault for MW-169.

Monitoring well MW-168 will pump recovered groundwater to the treatment system through the

same recovery zone as MW-169 (Northeast Zone 2). Data will be monitored in an ongoing

fashion. Following a three-month evaluation period, data will be evaluated to determine whether

long-term recovery from MW-168 and subsurface piping is warranted.

Groundwater extraction wells MW-178C and MW-183 currently exhibit the highest MtBE

concentrations of the wells located on 3501 Hampshire Glen Court (> 400 and 200 µg/L MtBE,

respectively). Groundwater recovery was initiated from MW-178C in December 2010 and from

MW-183 in July 2012. The existing pumps in MW-178C and MW-183 will be lowered from 150

fbg to 200 fbg to increase the hydraulic gradient toward these wells in an effort to accelerate

recovery of dissolved phase hydrocarbon constituents and potentially increase the capture zone.

Following initiation of groundwater recovery from MW-168, and the lowering of pumps in MW-

178C and MW-183, monitoring wells MW-43B, MW-91, MW-91D, MW-138D, MW-167, MW-168,

MW-176CC, MW-177, MW-178C and MW-183 will be gauged and sampled on a weekly basis for

the first month. Subsequent sampling of the aforementioned wells will return to their current

frequency. Sampling results will be included in the Groundwater Monitoring and Remediation

Status Reports submitted to the MDE on a quarterly basis.

14301 Jarrettsville Pike

Removal of Pump from MW-181B and Re-Installation in MW-181A

Monitoring wells MW-181A and MW-181B are located on the M&T Bank property at 14301

Jarrettsville Pike. Groundwater recovery was initiated in MW-181B on July 20, 2012. Since

initiating recovery in MW-181B, MtBE concentrations have fallen to below the MDE action level

of 20 µg/L, and results are often non-detect, while concentrations in MW-181A have remained

elevated (typically >100 µg/L MTBE) (Table 2). Initiating recovery from MW-181A is intended to

accelerate recovery of dissolved phase hydrocarbon constituents in the area, while groundwater

recovery from MW-181B is no longer warranted since concentrations have been below state

action levels since September 2014. The pneumatic pump will be deployed in MW-181A at a

depth of approximately 55 fbg. A trench will be excavated to connect new HDPE air and water

lines from MW-181A to the existing and adjacent subsurface remediation infrastructure located at

MW-181B. Following conversion from a monitoring well to a recovery well, MW-181A will pump

recovered groundwater to the treatment system via the same recovery zone as MW-181B

(Northeast Zone 3). MW-181A and MW-181B will continue to be sampled on their current

schedules.
