Purpose of EBSPurpose of EBSAn EBS is used to describe the currentenvironmental condition of the property withrespect to the presence of hazardous substancesand petroleum products for the followingpurposes:

§ To assess the progress of ongoingenvironmental restoration,

§ To identify areas where further responsemay be required, and

§ To facilitate reuse planning and propertytransfer efforts.

- BRAC Cleanup Plan Guidebook (1996)

Joint Use of DoD FacilityJoint Use of DoD Facility

n Facility is not scheduled for closure

n Facility is in reduced-operating status

n Under lease agreement(s), DoD will allow theCity to use portions of the property withoutinterfering with the DoD mission

n EBS evaluates environmental concerns andprovides a reference for development of leaserestrictions

Records SearchRecords Search

n Facility report

n Chain-of-title and property agreement

n Sanborn map search

n Well search

n Adjacent property search

15

Aerial Photograph Search & ReviewAerial Photograph Search & Review

n Identified and obtained available historicalphotos of the facility

n Reviewed and interpreted photos from 1939,1959, 1965, 1982, and 1994

n Identified areas of potential concern

Visual Site InspectionVisual Site Inspection

n Visual Site Inspection – evidence ofstorage, release/ potential to release, ordisposal of hazardous substances orpetroleum products

– Interior and exterior of buildings– Surrounding areas– Areas of potential concern

(identified from aerial photographs)

Area Types - DoD BRAC CleanupPlan Guidebook (1996)“Transferable” = Area Types 1 – 4

Area Types - DoD BRAC CleanupPlan Guidebook (1996)“Transferable” = Area Types 1 – 4

1 – Areas where no release or disposal of hazardous substances or

petroleum products has occurred

2 – Areas where only release or disposal of petroleum products has

occurred

3 – Areas where release of hazardous substances has occurred, but at

concentrations that do not require a removal or remedial action

4 – Areas where release, disposal and/or migration of hazardous

substances has occurred, and all remedial actions necessary to

protect human health and the environment have been taken

21

Area Types (continued)“Not Transferable” = Area Types 5 - 7Area Types (continued)“Not Transferable” = Area Types 5 - 7

5 – Areas where release, disposal, and/or migration of hazardous

substances has occurred, and removal or remedial actions are

underway, but all required remedial actions have not yet been

taken

6 – Areas where release, disposal, and/or migration of hazardous

substances has occurred, but required response actions have not

yet been implemented

7 – Areas that have not been evaluated or require additional

evaluation

22

Area Type DesignationArea Type Designation

Based on EBS findings, preliminary Area Typedesignations were made for:

– Buildings– Open areas– SWMU and IR sites– USTs and ASTs

Area Type designations are considered “preliminary”until NFA concurrence is received from regulatoryagencies

Environmental ConditionConsiderationsEnvironmental ConditionConsiderations

Parcels were designed to:

n Include properties of similar environmentalcondition

– “transferable” and “not transferable”property are in different parcels

n Include an estimated “buffer zone” toaccommodate potential contaminant migration

25

Joint Use Plan ConsiderationsJoint Use Plan Considerations

Parcels were designed to:

n Conform to Joint Use plans

n Restrictions and/or notifications necessary forreuse of each parcel will be designated in aFinding of Suitability to Lease (FOSL).

n Properties classified as “unsuitable fortransfer” (Area Types 5 through 7) may besuitable for limited reuse under a leaseagreement.

GIS Map in ArcViewGIS Map in ArcView

n Contains all information used to determineenvironmental condition

– Document review– Building inspections– SWMU/IR site conditions– ACM and LBP survey findings– UST and AST conditions

n Linked to Excel tables from EBS report

RecommendationsRecommendations

n Parcels designated “Unsuitable for Transfer”(Area Type 5 through 7) are recommended forfurther review and/or further action

n Specific recommendations provided in EBS

SummarySummary

n EBS is a reference document that presents the“baseline” environmental condition

n EBS facilitates reuse after transfer and/or jointuse under lease agreement

n EBS classifies environmental condition ofproperty considering cleanup and complianceprograms

n EBS presents data in various formats toaccommodate varying needs
