<br />Ryan Spencer, CHMM – Selected Project Experience
<br />Excelsior Road Improvements | Baxter, MN
<br />CLIENT: CITY OF BAXTER
<br />PROJECT DURATION: 2018
<br />As part of the Excelsior Road Improvements Project, Ryan
<br />managed and provided environmental planning and
<br />documentation services for the handling of petroleum
<br />impacts near an open leak site. The contaminates of
<br />concern for this project included DRO, GRO, and VOCs. The
<br />project required notification and coordination with the MPCA
<br />to issue a Corrective Action Letter, obtain a NPDES Pump-
<br />Out Permit to dewater, treat, and discharge contaminated
<br />groundwater, screen/segregate soil during excavation, and
<br />coordinate landfill approvals for offsite disposal. A total of
<br />100 cubic yards of impacted soil was removed from the site
<br />and 1.6 million gallons of impacted groundwater was
<br />pumped and treated via an activated carbon treatment
<br />system during construction. Since contamination was also
<br />present on the TH 371 right-of-way, coordination with
<br />MnDOT’s OES staff was performed. Upon completion of
<br />construction, WSB summarized the corrective actions in a
<br />final report that was submitted to the MPCA and MnDOT
<br />OES. The management provided by Ryan and WSB’s field
<br />staff was successful in managing petroleum impacts during
<br />construction and the site was issued closure by the MPCA.
<br />Block 34 Improvements | Monticello, MN
<br />CLIENT: CITY OF MONTICELLO
<br />PROJECT DURATION: 2016-2017
<br />As part of a downtown revitalization/improvements project,
<br />Ryan managed and assisted with the completion of a Phase
<br />I ESA, asbestos and regulated materials survey, demolition
<br />specification and bid documents, Phase II ESA, RAP, MPCA
<br />voluntary enrollment, and RAP implementation services for
<br />Block 34. The project required a Phase II ESA since land
<br />was being conveyed to MnDOT as part of the project. The
<br />contaminates of concern consisted of DRO, GRO, VOCs,
<br />SVOCs, PAHs, and metals. Both petroleum and non-
<br />petroleum contamination were discovered, therefore, Ryan
<br />worked closely with MnDOT OES and MPCA staff to obtain
<br />the necessary liability assurances prior to land conveyance.
<br />Ryan also managed RAP implemented during construction
<br />at the TH 25 at Broadway intersection, which resulting in 900
<br />tons of petroleum impacted soil to be removed and disposed
<br />offsite at a certified landfill. The RAP implementation
<br />services provided by WSB resulted in leak site closure by
<br />the MPCA. Additionally, the environmental services
<br />provided by Ryan and his team enabled the project to
<br />proceed without construction delays.
<br />CSAH 20 Improvements | Hopkins, MN
<br />CLIENT: CITY OF HOPKINS
<br />PROJECT DURATION: 2018
<br />For the CSAH 20 (Blake Road) Improvements project, Ryan
<br />managed and assisted with the completion of a Modified
<br />Phase I ESA, geotechnical investigation, Phase II ESA Work
<br />Plan, Limited Phase II ESA, HASP, and a RAP/CCP for the
<br />project corridor. The Modified Phase I and Limited II ESAs
<br />were completed on a rush timeline to ensure information was
<br />available for an aggressive project bidding schedule. The
<br />contaminates of concern consisted of DRO, GRO, VOCs,
<br />PAHs, and metals. The environmental documents were
<br />provided to Hennepin County Environmental Services and
<br />the City of Hopkins staff for review and approval. Three hot
<br />spot areas along the project corridor were identified due to
<br />elevated DRO and chloroform impacts to soil. In addition,
<br />Ryan and WSB’s field staff provided RAP/CCP
<br />implementation services during project construction to
<br />ensure all documented and undocumented contamination
<br />was managed in accordance with local, state, and federal
<br />regulations. The management, flexibility, and oversight
<br />provided by Ryan and WSB’s environmental team were vital
<br />for environmental planning and budgeting.
<br />CSAH 50 Improvements | Lakeville, MN
<br />CLIENT: CITY OF LAKEVILLE
<br />PROJECT DURATION: 2017
<br />For the CSAH 50 Improvements Project, Ryan managed
<br />and provided environmental and demolition services for the
<br />removal of five residential dwellings and two commercial
<br />buildings. The City of Lakeville acquired the sites to facilitate
<br />future City/Dakota County roadway improvements along the
<br />corridor. The contaminates of concern consisted of
<br />asbestos and other regulated building materials. Ryan
<br />provided environmental and demolition services for the
<br />project which included; completion of asbestos and
<br />regulated material surveys, sealing of five water wells,
<br />applying for County well sealing reimbursement funds,
<br />preparing demolition bid specifications, providing demolition
<br />oversight including documenting the removal of asbestos
<br />and non-asbestos containing regulated materials, and
<br />preparing documentation reports. The environmental
<br />services provided by Ryan and WSB’s field staff enabled the
<br />project to be completed on schedule and within the City’s
<br />allocated budget for dwelling/building removal.
