Consulting and Construction Management Services

Multiple Locations for Michigan Department of Management and Budget

The Michigan Department of Management and Budget (DMB) retained Superior to provide planning, design, bidding, and construction management services to accomplish the upgrade, replacement, removal, and closure of underground storage tanks (USTs) at sixteen state-owned properties located throughout the State of Michigan. Project sites included properties for the Department of Corrections, Department of Community Health, DMB, and the Family Independence Agency.

The projects were initiated to bring the properties into compliance with the rules and regulations of Part 213 of Michigan’s Natural Resources and Environmental Protection Act of 1994, Public Act 451. Superior project personnel met with the site representatives at each of the sixteen locations to verify the nature of the existing properties, the future needs of the property for fuel storage, and their individual preferences for USTs and aboveground storage tanks (ASTs). The initial site meetings also addressed security issues, potential conflicts between site operations and construction activities, and the location of existing underground utilities.

Based on the results of the site meetings, Superior developed specific recommendations for the removal, replacement, upgrade, and/or closure of USTs for each facility. Upon concurrence with the recommendations by the site contacts and the DMB Project Manager, Superior prepared detailed plans, specifications, bidding, and contract documents for each location. Superior also arranged for the appropriate state and local reviews of the contract documents.

Superior prepared the advertisement for bids, managed the distributions of bidding documents to the interested contractors, led the pre-bid meetings, reviewed the construction bids, and recommended the low, responsive bidder to DMB. Construction phase services included attending the pre-construction meeting, administering construction activity, shop drawing, partial payment review, on-site inspection, as-built drawings, and project closeout. During the construction phase Superior also collected the required soil and groundwater samples and prepared necessary UST closure reports in compliance with Part 213.

National Entertainment Company, Detroit Michigan

Phase I and Phase II Environmental Site Assessments, Construction Management

A national entertainment company retained Superior to complete a Phase I Environmental Site Assessment (ESA) on three separate parcels of property in the Metropolitan Detroit Area. Phase I ESA activities disclosed several potential environmental concerns including possible asbestos-containing building materials, foreign fillmaterial, and the probability of one or more underground storage tank (USTs) on-site.

Real estate negotiations necessitated that the project be placed on a “fast-track” to complete all environmental activities prior to closing on the property. Superior personnel completed initial Phase II ESA activities, which consisted of eight soil borings placed on the largest and most developed parcel of property. Laboratory analytical results evidenced historical contamination of a sufficient concentration to define the site as a “Facility.” After briefing the client and their attorneys, a larger Phase II ESA scope was developed. In 2-working days, Superior completed 64 soil borings over the three parcels of property. Collected soil samples were submitted to an independent laboratory for rush analysis. Following receipt and review of the laboratory analytical results, it was determined that sufficient evidence had been collected to complete Baseline Environmental Assessments (BEAs) on the three parcels.

Based on information obtained during the Phase I ESA in conjunction with the field survey, it was determined that it was probable a UST did exist on the property but had been abandoned for several years. During the second Phase II field activities, Superior personnel also conducted a metal detector survey in the suspect area of the probable UST location. Superior retained the services of a qualified subcontractor to conduct an exploratory excavation to verify the presence or absence of a UST. During this activity, a 6,000-gallon UST was exposed and found to contain 6,000 gallons of diesel product. A confirmed release and Notice of Free Product was subsequently reported to the Michigan Department of Environmental Quality (MDEQ) Storage Tank Division (STD), based on the presence of free-phase product in the excavation basin.

Superior personnel subcontracted the services of a licensed waste reclamation company to remove the 6,000 gallons of product from the discovered UST and to remove the product that accumulated in the tank basin. During the free product abatement activities, a second UST was discovered to exist in the same tank basin. This 1,000-gallon UST was found to be filled with sand. The newly discovered UST was subsequently registered with the MDEQ STD on behalf of the current owner of the property. Both USTs were removed and transported to a scrap metal facility for recycling.

At this point of release discovery, Superior personnel discussed remedial options with the client, the current property owner, and their respective attorneys. In the essence of time and to allow the property sale to proceed, excavation and disposal of the impacted soil was determined to be the most practical and economical solution for remediation of the UST basin. This decision was based on the fact that groundwater was absent from the site, subsurface geology was predominantly clay soils, and earlier Phase II ESA laboratory analytical results defined the extent of petroleum impact to be limited to the discovered UST basin.

Following receipt of approval from the landfill, Superior personnel coordinated the excavation and disposal of 308 cubic yards of impacted soil to a licensed Type II landfill. Appropriate verification of soil remediation soil samples were collected and sent to an independent laboratory for rush analysis. The laboratory analytical results revealed favorable results that would allow Superior personnel to complete and submit a Site Closure Report. The excavation basin was consequently backfilled and the area resurfaced with concrete.

Concurrent with these activities, Superior personnel completed the BEAs for the three parcels of property. Working with the client, the current property owner, their attorneys, and staff from the MDEQ, Superior was able to obtain and provide all information necessary for a BEA determination and acceptance on each parcel of property based on their intended use. Following receipt of the laboratory analytical data, Superior personnel also prepared and submitted a Site Closure Report under the Tier I Residential Closure category for the discovered USTs. All related environmental issues had been addressed, resolved, and/or remediated to each party’s satisfaction.

Superior’s client elected to choose an alternate location for development. This decision was not due to the environmental issues, which were resolved. As their project scope and needs expanded, additional building space was needed. Superior was retained by our client to begin anew on the alternate location selected for development.

Superior successfully completed the Phase I, Phase II, and BEA process on the alternate location selected by the client. Site renovation activities were completed and the facility is in full operation with staff and equipment. Superior also developed a working relationship with the owner of the original property slated for development. The owner’s realtor found another buyer for the property, and Superior completed BEAs for each parcel of property on behalf of the buyer.

Construction Management and UST Compliance Reporting

Utility Company in Michigan’s Upper Peninsula

A utility company retained Superior to complete underground storage tank (UST) removal, UST upgrades, and the installation of new USTs or aboveground storage tanks (ASTs) at seven company properties located across Michigan’s Upper Peninsula. The UST and AST systems were designated to provide fuel to auxiliary generators in the event of a power failure. Superior managed construction activity at all sites, which included UST removals, replacements, and up-grades.

Confirmed releases were discovered and subsequently reported for five of the seven properties. The UST Site Assessment Report Form was completed and submitted to the Michigan Department of Environmental Quality (MDEQ) Storage Tank Division (STD) for the two remaining properties, which evidenced no contamination following removal of the UST systems. Closure Reports were submitted for three of the five remaining facilities following the site hydrogeological investigations. The results of the hydrogeological investigations provided sufficient evidence to close the sites under the Tier I Residential Closure category using the Risk Based Corrective Action (RBCA) process.

Additional investigations were needed at the two remaining contaminated properties. Each site was unique with respect to existing subsurface conditions. At one site, approximately 90 cubic yards of petroleum-impacted soil was excavated during removal and replacement of the old UST system. The shallow depth of the local bedrock prevented contaminant migration but also limited excavation capabilities. At the other site, extensive underground utilities inhibited excavation as a remedial option and severely limited any subsurface investigative work. Additional environmental work resulted in closure of the remaining sites.
