Additional Property Attributes

Summary of Phase I Environmental Site Assessment:
SEH was retained by the City of Duluth to complete a Phase I ESA on behalf of Ursa Minor,
and was completed in October of 2020 (SEH, 2020). The Phase I ESA identified a single
recognized environmental condition (REC) associated with adjoining properties that were
utilized as fueling stations, repair shops, and bulk fuel facilities since the 1920's. This includes
four petroleum leak sites: DJ Fastener Inc. (LS0013582), Harbor City Oil Inc. (LS0014682),
Rohlfing of Duluth Inc. (LS0020677), and the Duluth City Sewer Toolhouse (LS0002620). The
Phase I ESA also identified a potential soil vapor concern associated with the petroleum leak
sites located adjacent to and within the vicinity of the Site and fill of unknown origin at the site.

Summary of the Phase II Environmental Site Assessment:
SEH also completed a Phase II ESA, Ursa Minor Phase II Environmental Site Assessment,
Duluth, Minnesota (SEH, 2020). The Phase II ESA is included in Appendix A.
The Phase II ESA included four soil borings advanced to a maximum depth of 20 feet below
ground surface (bgs), and four soil vapor probes. Soil encountered during the Phase II ESA
consisted of unconsolidated fill material, consisting of poorly graded sand and lean sandy clay.
The fill material extended to approximately 4 to 9 feet bgs underlain by silty sand and clayey
glacial outwash. Groundwater was encountered in three of the borings at a depth ranging from
9.0 to 12.5 bgs. Both soil and groundwater samples were analyzed for presence of DRO,
gasoline range organics (GRO), volatile organic compounds (VOC), polycyclic aromatic
hydrocarbons (PAH), and Resource Conservation & Recovery Act (RCRA) 8 metals. Soil vapor
samples were analyzed for VOCs.
Soil encountered during the subsurface investigation had concentrations of DRO that exceeded
the MPCA unregulated fill criteria at two soil borings. BaP equivalents concentrations exceeded
the Tier 1 Residential SRV in three soil boings. Exceedances of the MPCA Tier 2
Commercial/Industrial SRVs were not identified during the subsurface investigation.
Groundwater encountered during the subsurface investigation had DRO concentrations that
exceeded the MDH HBG of 50 micrograms per liter (ug/L) in all groundwater samples ranging
from 151 to 400 ug/L. A BaP concentration exceeded the MDH HBV of 0.10 ug/L in one boring.
No additional analytical compounds were detected in the groundwater which exceeded the
applicable groundwater regulatory standard.
RESPONSE ACTION PLAN/
RESPONSE ACTION PLAN/CONSTRUCTION CONTINGENCY PLAN DULUT 157361
3
Soil vapor samples collected during the subsurface investigation were below
Commercial/Industrial Intrusion Screening Value (ISV).
Response Action Plan:
The Phase II ESA identified soils with DRO concentrations exceeding the MPCA UFC and BaP
exceeding the Tier 1 SRV; however, all soil met MPCA Tier 2 SRVs for Commercial properties.
No elevated PID headspace readings were recorded.
Anticipated construction includes the installation of footings for a deck expansion. Regulated
soil generated for footings will be managed on-site. If excess soil is generated that cannot be
reused on-site, soil will be disposed in a permitted landfill. Alternatively, reuse of regulated soil
off-site would be completed in accordance with the MPCA's policy (Off-Site Use of Regulated
Fill Policy, c-rem2-02 March 2012).
Construction Contingency Plan:
If construction encounters contaminated or regulated materials the contractor will immediately
stop work in the vicinity. The contractor will not resume Work in the suspected area until
approved by the project owner, Ursa Minor. If unforeseen contaminated or regulated materials
are encountered during construction, appropriate reporting and regulations will be followed.
Ursa Minor would enlist an environmental consultant to respond to evaluated contaminated and
regulated materials conditions.
