1 Case Study: Starkey Junk Yard, Uhrichsville VAP Annual Training September 12, 2003

2 Introduction! General site history! Phase I summary! The targeted brownfield assessment process " Early steps " DQO scoping meeting! Field work performed! Results and next steps

3 Site History Starkey Junk Yard! Over sixty years as an auto salvage yard.! Mixed industrial and residential use.! Numerous potential releases! Currently a blight and a hazard to the residents of Uhrichsville.

4 Starkey Junk Yard - Adjacent Property

5 Starkey Junk Yard - Adjacent Property

6 Site Background! Auto salvage yard on the Property since before 1938.! All potential sources and source areas associated with on-property activities.! Potential releases: " Salvage operations including automotive fluids, used batteries, scrap metals and burned tires. " Scrap tire fire in " Open dumping complaint in 2002 industrial waste, metal, oil, welding materials and slag.

11 Identified Area Summary! Identified Area #1: Junk Shop Area (Existing building and concrete pads from former buildings).! Potential sources include automotive fluids and batteries. COCs include VOCs, SVOCs, TPH and Metals.

12 Junk Shop Area

13 Dense Vegetation North

14 Dense Vegetation South

15 Identified Area Summary! Identified Area #2: Compactor Area (Concrete pad in southwest portion of scrap yard where hydraulic pumps were used to operate a compactor).! Potential sources include automotive fluids, hydraulic oils (possibly containing PCBs), metals and batteries. COCs include VOCs, SVOCs, TPH, PCBs and Metals.

16 Scrap Yard Area

17 Compactor Area

18 Identified Area Summary! Identified Area #3: Scrap Yard Area (The remainder of the Property).! Potential sources include automotive fluids, metals and batteries. COCs include VOCs, SVOCs, TPH and Metals.

19 Proposed Reuse! The Village of Uhrichsville wishes to reuse the property as a park and baseball diamond.! The village sought a grant-funded targeted brownfield assessment (TBA) from Ohio EPA to provide support for a VAP Phase II investigation.! The results will be used as part of an application for Clean Ohio Fund cleanup money.

20 Requesting a TBA! Submit a TBA application form and formal request letter.! Receive request for additional information, explanation of deficiencies, or invitation to a kickoff meeting from Ohio EPA.! Attend kickoff meeting to discuss scope of project.! Work with district or SIFU to develop work plan and data quality objectives (DQO).

21 TBA Process! Ohio EPA staff visited the site and learned the community s assessment needs.! A DQO scoping meeting was held between Ohio EPA staff, the community and their CP prior to developing a work plan.

22 TBA Process! DQO scoping meeting " Benefits of coordination between CP, community and agency! Staff, personnel, field work, etc. A meeting of public and private interests.

23 CP s Goals for DQO Meeting! Discuss proposed ecological studies by SIFU to characterize sensitive ecological receptors.! Identify geologic and hydrogeologic conditions below the Property.! Collect both POC and subsurface soil samples in Identified Areas.! Collect screening data to characterize ground water across the Property.! If possible, use a VAP Certified Laboratory to perform analysis.! Assure that laboratory MDL s comply with VAP generic standards.! Request the CL provide a VAP Affidavit along with their reports.

24 DQO Scoping Meeting Discussion Agenda Outline I. Introductions II. State/Define the Problem (describe the data-gathering activities) i.e. - Adequately assess the contamination problem(s) that might exist at the site. III.Identify the Decision i.e. - Collect data of sufficient quality and quantity in order to provide the basis for the identified further action(s) at the site. IV. Identify Inputs to the Decision C-O-C s? VAP considerations? Enforcement Issues? Other potential technical issues? V. Define the Study Boundaries Physical characteristics of the site/property Eco Assessment Groundwater issues? Additional areas to investigate (waste piles, storage tank area, etc.)?

25 DQO Scoping Meeting Discussion Agenda Outline VI. Develop a Decision Rule If the concentration of contaminants at exceed then the site shall be,... VII. Specify Limits on Decision Errors Soil Borings (method/ location/number/depth) Piezometers (method/location/ number/depth) Groundwater Samples (method/location/number/ depth) Soil Sampling (Procedures/ analytes/methods) Groundwater Sampling (Procedures/analytes/ methods) Time-frame for field activities Turn-around time for analytical data Reports VIII.Optimize the Design

27 Field work! The Geoprobe was used to sample soil.! A hand auger was used to collect soil samples in terrain not accessible with the Geoprobe.

28 Field Work Establishing a piezometer using the Geoprobe.

29 Field work Samples were screened for VOCs, PCBs and metals onsite using the mobile lab.

30 Field Work! A geologist was on site to examine and log soil cores.! Soil samples collected with the Geoprobe can be screened on site or sent to a fixed-based lab for analysis.

31 Field Work! Samples were screened for VOCs, PCBs and metals onsite using the mobile lab.! Confirmatory samples were sent to the State-contract VAP certified lab.

32 Ecological Assessment Ohio EPA Division of Surface Water, Ecological Assessment Section staff returned to the site in August to assess biological and water quality and to conduct sediment sampling in Stillwater Creek adjacent to the property.

33 Ecological Assessment

34 Ecological Assessment

35 Findings of the SIFU investigation! Lead and arsenic exceed residential DCSS in all areas - compactor, junk shop, scrap yard, vegetation north and vegetation south. (Lead also exceeds commercial/industrial standard.)! TPH (DRO) in soil exceeds petroleum standards in compactor area only.! VOCs, SVOCs, PCBs all present, but below residential DCSS.! Lead in ground water exceeds generic standard (to be verified through monitoring well installation and sampling).

36 Tasks to be completed! Complete Phase II Property Assessment to include ground water characterization, ground water classification and (probably) risk assessment.! Implement remedies that may include O&M Plan, Risk Mitigation Plan, Property Use Restrictions or cover materials.! Estimate remediation costs and apply for Clean Ohio funding.

37 With all of the efforts put into this project, the end result is a true "thumbs-up" experience.
