Additional Property Attributes

Available historical records indicate the property remained undeveloped until approximately 1960. It has operated as a surface parking lot since that date. City Council has approved acquisition of the property for the creation of a new park (https://siouxcityjournal.com/news/local/govt-and-politics/new-park-proposed-for-mid-town-area-of-sioux-city/article_69ae258d-49d4-5d2e-bf22-41151a0bcfce.html). Officials estimate a $200,000 equipment investment.

The findings and conclusions of the Phase II ESA are summarized as follows:

Soil: A total of two (2) TEHs detected in soil samples, waste oil and total extractable hydrocarbons. Reported concentrations did not exceed applicable statewide standards (SWSs).
Groundwater: A total of two (2) TEHs detected in groundwater samples, waste oil and total extractable hydrocarbons. Waste oil was reported at a concentration above the protected groundwater (PGW) SWS, above the most restrictive Tier 1 threshold (groundwater ingestion), and below the non-protected groundwater (NPGW) SWS. Five (5) VOCs reported as non-detect values at their laboratory reporting limit, however this limit is above an applicable SWS. Detected and non-detect values above a SWS were put into the Risk Calculator.

Vapor: Five (5) VOCs had laboratory reporting limits greater than a corresponding SWS and are sufficiently volatile and sufficiently toxic to present a vapor intrusion risk. 1,2-Dibromo-3-chloropropane is sufficiently volatile and sufficiently toxic, however is not included in the Johnson & Ettinger Vapor Model and as such cannot be included in this calculation. The remaining VOCs were evaluated using the Johnson & Ettinger Vapor Intrusion Model for Forward Calculation of Indoor Air Concentration.

The results from the study identified acceptable cancer and non-cancer risk for site residents, site workers, and construction workers as there is no well on the subject property and the City of Sioux City has an IDNR-approved groundwater ordinance in place.

Detected groundwater waste oil concentrations were observed above the PGW SWS and Groundwater Ingestion Tier 1 Look Up threshold. When the groundwater pathway is considered an elevated groundwater risk is identified due to non-detect values and a conservative risk determination approach where the non-detect values were used to calculate risk for each compound with the laboratory reporting limit above the applicable SWS. As noted above, the City of Sioux City has an IDNR-approved ordinance (No. 99-07725) that effectively prevents the installation of private wells and there is currently no well on the subject property. Public water supply appears to be available to the subject project. As such, the groundwater pathway is severed and this is reflected in the risk calculations.

The report recommended it be provided to IDNR to review.
