About this file
This document provides information on a draft solicitation for optimized environmental remediation services at Joint Base Andrews. The U.S. Army Corps of Engineers Baltimore District seeks these services to support the base's Environmental Remediation Program. The performance-based contract will require the contractor to conduct all necessary remediation activities to achieve the objectives outlined in the draft solicitation. This includes ongoing work at over 30 identified sites involving releases of fuels, solvents, and other contaminants. Feedback on the draft solicitation is due by October 4th via the projNET website. A final solicitation with a request for proposals will be issued at a later date. The optimized remediation contract aims to complete ongoing investigations and remedial actions, achieve regulatory closure at sites where possible, and reduce long-term lifecycle costs under the oversight of the Army Corps and federal and state regulators.

Andrews Sites
Andrews has been in operation since 1943. As expected with over half a century of functioning as a active air base, there have been several releases of contamination into the environment.
These sites fall into several broad catagories:

UNCLASSIFIED
JB Andrews Regulatory Status
JB Andrews in on the NPL – with Federal Facility Agreement (FFA)
Brandywine DRMO is on the NPL – Separate listing and FFA
Davidsonville is NOT on the NPL – State regulated cleanup
UNCLASSIFIED
CERCLA/ NON-CERCLA
Two kinds of sites
CERCLA – Subject to the FFA No Permits, that includes wells.
RI must be based on high quality defensible data.
Still have to meet Applicable Requirements (ARARs).
Includes Sediment and Erosion control.
Non-CERCLA: Petroleum only. Regulated by the Maryland Department of Environment Oil Control Program. (ST-08/SS-22) Need well permits.
If Remediation system is in place than applicable permits are required.
If removal occurs then Sediment & Erosion Control / Storm water permits may be required.
SS-11 is State regulated cleanup under Federal Facility Program.
UNCLASSIFIED
Wells
Wells in Maryland!
If applicable well permits are filed with County.
Well abandonment requires rig mobilization.
No stick up wells in the Airfield.
Two inch wells are fine now.
WELL DATA MUST BE PROVIDED TO ERPIMS!
UNCLASSIFIED
ERPIMS
AFCEC manages the USAF Environmental Resources Program Information Management System (ERPIMS).
https://www.afcec.af.mil/What-We- Do/Environment/Restoration/ERPIMS/
UNCLASSIFIED
Code of Maryland REgulations
Sediment & Erosion Control / Storm water Management
On USAF property these plans are reviewed by the state. There is no County Grading Permit process for work on USAF property.
Where will you need these? Excavations.
Plan on working with an expeditor.
Budget for Super Silt Fence.

UNCLASSIFIED
Review Times
Ignore the FFA review times.
Working Copy to USAF and USACE for review. We are pretty good at turning these around in about 30 days… at least until lately…
Once RTCs have cleared then the document can be submitted to regulators. Expect EPA comments in 45 to 75 days (the current record is over a year).
UNCLASSIFIED
Review Times
EPA comments can be very challenging to reconcile. You may need to work with USAF in doing so. Some will actually require USAF response (like PFAS related comments)
Maybe say… another 45 days to reconcile RTCs. Then the document can go final… if it made it through OPSEC & Policy Review.
UNCLASSIFIED
But wait… there’s more!
ESDs, RACRs, FS, PPs, and RODs require USAF legal review. This typically takes 21 days.
ESDs, RACRs, PPs, and RODs require EPA legal review. This is typically 60 days.
Any changes made by EPA must be rerun by USAF legal!
UNCLASSIFIED
Typical FS if there are no major issues
Working Copy – USAF/ USACE review 4 weeks
Revise per comments 1 week
Back check/resolution by USAF /USACE 2 weeks
USAF Legal review 3 weeks
Revise/receive USAF legal approval 3 weeks
Regulator Review of Draft 8 weeks
Revise per regulator comment/USAF approval 4 weeks
USAF legal check/approval 2 weeks
Regulator review/approve responses 4 weeks
Draft Final OPSEC & Policy Review 1 week
Finalize Total 32 weeks after initial submittal
UNCLASSIFIED
There will be a slight delay.
ESDs, RACRs, and RODs need USAF signatures.
4 to 6 months!
UNCLASSIFIED
Records of Decision
JB Andrews RODs are highly prescriptive.
Almost any change in a remedy will likely require an ESD.
Keep in mind how long an ESD will take to get in place if you are proposing a change in a remedy to save in life cycle costs, or establish an alternative approach.
UNCLASSIFIED
Emerging Contaminants
PFOS/PFOA
1,4 Dioxane
Impact on Investigation Derived Waste?
No central USAF policy… yet… Current JB Andrews Policy… manage as unregulated waste unless the IDW was generated specifically for sampling for PFAS.
This policy may change in the future.
UNCLASSIFIED
MDE Oil Control Program
We have two sites in the ORC managed by MDE Oil Control.
CERCLA process and approach are NOT applicable.
MDE will close a site based on qualitative risk.
MARYLAND ENVIRONMENTAL ASSESSMENT TECHNOLOGY for
LEAKING UNDERGROUND STORAGE TANKS
Yes that is the MEAT Guidance:

UNCLASSIFIED
MDE Oil Control Program
MDE Site Closure No Source No Free Product (just sheen or preferably less) No One Drinking It Levels Trending Down
In USAF program MDE site closure is equivalent to RC. The site cannot be SC until you reach UU/UE.
UNCLASSIFIED
QAPPS
We have agreement from the regulators that there can be one basewide UFP Quality Assurance Program Plan (QAPP) for the contract…
… kind of sort of….
Each project/site needs a QAPP specific to each project. Wherever possible it should refer to the basewide QAPP to limit the size and review time.
