Additional Property Attributes

"The Phase II Addendum ESA indicated that volatile organic parameters were detected in the soil samples. However, the concentrations were below their Missouri Risk-Based Corrective Action (MRBCA) lowest Default Target Levels (DTLs) or Risk Based Target Levels (RBTLs). All 12 Polynuclear Aromatic Hydrocarbons (PAHs) compounds were detected in one or more soil samples. PAHs detected above their DTLs include benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, and dibenz(a,h)anthracene. Benzo(a)pyrene also exceeded its Residential and Non-Residential Ingestion, Inhalation and Dermal RBTLs during the initial Phase II ESA. Benzo(a)anthracene, benzo(b)fluoranthene, and dibenz(a,h)anthracene also exceeded their Groundwater Pathway RBTLs. Lead exceeded the Groundwater Pathway RBTL in every soil sample collected. However, shallow groundwater is not used at the site. A Memorandum of Agreement between the City of St. Louis and MDNR restricts groundwater usage. Concentrations of lead in two surface soil samples (SB14 and SB16) and two subsurface samples (SB8 and SB12) exceed the Residential Ingestion, Inhalation and Dermal RBTL for Soil Type 1. With the exception of lead, no pattern to distribution was apparent for chemicals of concern. PAHs were found widespread throughout the site. The sporadic distribution of PAHs indicates no specific source and is possibly a result of the combination of fill material, vehicular fumes from leaded gasoline, and former gasoline station activities. Lead in the surface soil appears to have a surface plume that runs through the center of the site. Benzo(a)pyrene was detected in surface soil exceeding its Residential Ingestion, Inhalation and Dermal RBTL in SB2, SB4, SB6, SB15 and SB16. Benzo(a)pyrene was also detected in surface soil during the initial Phase II ESA exceeding its Non-Residential Ingestion, Inhalation and Dermal RBTL in SB2 and SB6. Lead exceeded its Residential Ingestion, Inhalation and Dermal RBTL in surface soil samples from SB14 and SB16. Lead from the surface soil collected from SB14 also exceeded the Non-Residential Ingestion, Inhalation and Dermal RBTL and may pose a risk to construction workers on the site. Lead was detected in the subsurface soil collected from SB8 above its Residential Ingestion, Inhalation and Dermal RBTL. The contractor attempted to probe the area of the possible underground storage tank (UST) but found the test to be inconclusive due to the amount of buried debris present in the area. One magnetic anomaly with dimensions similar to a 1,000-gallon tank or larger was identified during the initial Phase II ESA. The anomaly measured approximately 5.5 feet by 8 feet. The possible UST is located in the central and western half of the site."

Former Use: Past site uses include Clark Gas Station from 1971-1995 and Bakery and Ice Cream Store from 1927- 1971. There are no buildings on this .20- acre site. One underground storage tank is known to have been closed in place, but the fate of the other four tanks is currently unknown. Anticipated future use is to market the site for redevelopment. Based on results of the Phase II Addendum ESA, BVCP recommends enrolling into the Voluntary Cleanup program and one or more of the following options: 1) Perform a TierI/Tier II Risk Assessment based on the collected data. 2) Excavate to determine if any USTs reside on the site, and if so, to properly remove any USTs according to MDNR guidelines. 3) Remove the surface soil surrounding the areas that exceed Non-Residential criteria and place a Land-Use Restriction to zone the site for non-residential use. 4) Place a barrier on the site with a Land-Use Control in place to maintain the barrirer. 5) Excavate the entire 0 to 3 feet bgs of surface soil on the site and place clean fill on the surface.
