Currently owned and used by Jackson Housing Authority consists of one 17,500 sq ft building for office space and a warehouse/work area. RECs identified include an onsite UST system and off-site, nearby former auto, chemical, and furniture manufacturing companies. JHA intends to demolish the building and redevelop the property to include their new headquarters and some affordable housing once environmental conditions are addressed and funding for the redevelopment is finalized.
Phase II ESA activities, conducted by PPM Consultants, Inc. (PPM) (www.ppmco.com) were conducted in spring 2023 (Report dated March 27, 2023) and a 20,000-gallon diesel tank, a 4,000-gallon engine oil tank, a 2,500-gallon antifreeze tank, and a 1,000-gallon used oil tank were removed to complete the Phase II ESA. An ACM survey, conducted by PPM was also conducted and no ACM was identified after sampling was completed. A UST Tank Closure Report, dated April 19, 2023 documented the tank closure procedures. The tank removal was conducted in accordance with the Mississippi Department of Environmental Quality's (MDEQ) Guidelines for the Permanent Closure of Petroleum Underground Storage Tank Systems (MDEQ July 1, 2009).
From the Phase II ESA, CONCLUSIONS - The conclusions are based on or are reasonably ascertainable from, published information, field observations, and the results of specific laboratory analyses.
- In general, asphalt/surficial soil was underlain by a low to medium plasticity, soft to firm, homogeneous, moist to wet, tan/reddish-tan/gray-brown/gray/light gray silty
clay that extended from surface to approximately 12 feet BGS. These silty clay were underlain by similar silty clays that were heterogeneous from approximately 12 feet
BGS to boring termination.
- BTEX and MTBE were not detected above laboratory detection limits in soil samples SB-1 through SB-3.
- PAHs were detected in soil samples SB-1 (0'-2'), SB-2 (0'-2'), SB-3 (0'-2'), SB-3 (34'-36'), SS-SC (13'), SS-NC (13'), SS-NW (13'), PL-1 (3'), PL-2 (3'),
SP-1, SP-2, and SP-3. Detected PAHs included acenaphthene, anthracene, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(g,h,i)perylene,
benzo(k)fluoranthene), chrysene, dibenz(a,h)anthracene, fluoranthene, fluorine, indeno(1,2,3-cd)pyrene, 2-methylnaphthalene, naphthalene, phenanthrene, and/or
pyrene. Detected PAH concentrations were below their respective MDEQ Tier 1 Unrestricted TRGs.
RECOMMENDATIONS - Concentrations of detected constituents are below their MDEQ Tier 1 Unrestricted TRGs in the soil samples collected. Therefore, based on the findings of this assessment, no additional assessment is warranted.
