Climate Adaption and Mitigation - Planning or Assessment

Selected Strategy(ies)Explanatory Text
Evaluate Reuse options that consider impacts from extreme weather events and natural disastersDiscussion of observed and forecasted natural hazard conditions and the associated site-specific risk are part of any reuse considerations. Both current and forecasted extreme weather events and natural disasters may impact the effectiveness of a remedial alternative.

Climate Adaption and Mitigation - Demolition or Cleanup

Selected Strategy(ies)Explanatory Text
Selection and design of cleanup considered the site's vulnerabilities to extreme weather events and natural disastersVulnerability describes the degree to which natural, built, and human systems are at risk of exposure to impacts from extreme weather events and natural disasters.
Design of cleanup allowed for siting of weather-related and disaster-related resiliency measures in site reuseThe capacity of a system to maintain function in the face of stresses imposed by extreme weather events and natural disasters and to adapt the system to be better prepared for future related impacts.
Sustainable land management practicesSustainable land management practices capitalize on a "whole-site" approach that accelerates cleanup while returning a site to its natural conditions. Practices focus on opportunities to preserve natural land features, maintain open space, sequester carbon, enhance biodiversity, increase wildlife habitat, and minimize surface and subsurface disturbance. Sustainable land management practices at a brownfields site may include minimizing unnecessary soil and habitat disturbance or destruction; use of native species to support habitat; and onsite remediation approaches such as bioremediation and/or phytoremediation.

Additional Property Attributes

The Subject Property consists of approximately 185 acres of undeveloped land northwest of McAlester, Oklahoma. Several ponds and wetlands that drain toward Lake Talawanda 1 are located on the property. A shooting range, leased to the Eufaula Rod and Gun Club since approximately 1987, is located on the western portion of the property along Water Works Road. A Phase II ESA was conducted to aid in the determination of whether impacts from the shooting range pose a risk to human health by collection, analysis, and evaluation of soil, sediment, surface water and fish tissue samples.

The Phase II ESA found the following: Soil - The results of the soil sampling from borings collected from the range, and a boring collected from a background area outside of the range, indicated that elevated concentrations of antimony, arsenic, copper, and lead were present in the sampled soils. Because soil concentrations of antimony, copper, and lead did not exceed Resident SSLs protective of human health, and arsenic concentrations were within the background range for Oklahoma soils, none of the elevated soil concentrations were likely to pose a risk to human health via contact or ingestion. The SPLP lead concentrations exceeded the MCL, indicating that lead has the potential to leach from the soil to the groundwater.

Sediment - Antimony, arsenic, and lead were detected in the sampled sediments in excess of the limiting RSLs. Lead was detected in sediments collected from Ponds 2 and 3 in excess of the Resident SSL. These ponds are immediately downgradient of the shooting range. The lead concentrations in these sediments may pose a risk to human health via contact or ingestion.

Surface water - Dissolved antimony and dissolved lead exceeded Surface Water Quality Standards (SWQS) in one sample. Pond 2 is connected to the other ponds during high water; however, the sampling was conducted during a period of drought and low water conditions. The ponds did not appear to be flowing during the sampling event. Samples collected from the downgradient ponds did not exceed SWQS.

Fish Tissue - Arsenic concentrations in fish tissue exceeded the calculated RSL in all samples and exceeded the EPA guidance concentration in the samples collected from the ponds closest to the shooting range. No federal standards for lead were found in the literature; however, higher lead concentrations were detected in fish collected from the ponds closest to the shooting range, suggesting that historical site activities may have impacted aquatic life in these ponds. The fish tissues collected from Lake Talawanda contained lead in concentrations one to two orders of magnitude lower than in the ponds closer to the shooting range.

The Analysis of Brownfields Cleanup Alternatives is being drafted as of 10/16/24.
