ACTION REQUESTED: Signature of SitewideReady for Anticipated Use (SWRAU) by the Division Checklist for Redwing Carrier, Inc. Superfundsite in Saraland, Mobile County, Alabama.

REMARKS: All cleanup goals at the Sitehave been achieved and no ICs are required to ensure continued protection ofhuman health and the environment. The2014 Remedial Action Report contains the supporting documentation indicating that contaminated site soil was removed and disposed of at an approved facility and the groundwater was monitored until which time whenthe sampling results indicated that thesite had met therequirements ofthe remedial documents.
The ROD was signed in 1992 and an AROD was signed in 1999. The AROD allowed for the demolition of site pavement and structures for full remediation ofthesite and delayed the implementation oftheground water treatment until an evaluation ofthe ground water post soil removal action could be evaluated. In September 2007 EPA issued an ESD to update thesite's hydrogeology and the effectivedepth to groundwater based on findings duringthe 1996 Removal Action. The ground water monitoringresults indicated that the 1992 ROD ground water treatment would not be necessary to meet the remedial goals.These findings determined that four ofthe subsurfacesoil cleanup levels required updating. The remedial objectives remained unchanged.



### The Redwing Carriers, Inc. Superfund site meetsthe SWRAU criteria.

4.4.6 Monitoring Well Abandonment At the completion of the RA, the contractor abandoned all existing monitoring wells on the Site in accordance with the ADEM regulations, with the exception of the two (2) deep wells on the eastern boundary of the Site (Figure 4-9). The abandonment of the wells followed the general guidelines including:

• Casing pulled and theborehole sealed up to gradewith concrete; and

• Debris generated from the well abandonment proceduredisposed of off-site.

4.4.7 Demobilization The contractor removed all pumps, holding tanks, trailers, and other equipment from the site and all Site equipment and other facilities. Site roadways and public access features were restored to their original condition. Perimeter fencing was repaired as needed.

The Site was restored to as natural condition as much as possible to blend in with the surrounding properties. All Site documentation was provided to the OAR for records retainage. Site demobilization was completed onJune 27, 2008,

4.4.8 Compliance with the ROD The RA at the Saraland Superfund Site is compliant with the ROD and the associated Scope of Services for soils. Specifically, the RA iscompliant with the RODas follows: Objective 1 - Prevent or mitigate the release of pollutants and contaminants to the surficial water-bearing unit beneath the Site. The Site was excavated. The excavation bottoms were analyzed and the 90% UCL concentrations, for allconstituents, are below the ROD and ESDclean-up standards. Objective 2 - Reduce the concentrations of pollutants and contaminants in the surficial groundwater at the Site tothe cleanup levelsspecified inthe ROD. As of August 2012, the groundwater at the site has attenuated to and Is compliant with the ROD groundwater protection standards. Also, 4 years of off-site monitoring has shown no detectablecontamination off of thesite property.

49Objective 3 - Prevent on-site exposure via direct contact with surfacesoils at concentrations that

pose an unacceptable risk to human or environmental receptors under a residentialscenario.
The surface soils at the Site now consist of clean backfill. Therefore, there is no exposure risk to site constituents in surface soils. Objective 4 - Prevent on-site exposure via direct contact with subsurface soils at concentrations that pose an unacceptable risk to human receptors under construction or subsurface utility worker scenarios.
Elevated concentrations of subsurface soil (above ROD and ESQ standards) no longer exist at the Site property and no subsurface soils are exposed. Therefore, there is no exposure risk to site constituentsin subsurface soils. Objective 5 - RemoveTLM to prevent nuisanceexposure at theground surface.
All TLM and TLM soils were removed from the Site except for a small subsurface area remaining around the main natural gas lineon the northern propertyboundary.

Additional Objective- Remove allexisting buildingsfrom the site. The demolition program described earlier in this report provided for compliance with the demolition requirements of the ROD. All Site buildings, features, pavement and subsurface piping thatwere located duringdemolition were removedfrom the Site.

v 4.4.8.1Surface Soils

The entire surfaceof the Site has been backfilledand gradedwith clean fillfrom either off-siteor on-site locations. No surface soil exposure risk remains on Site.

4.4.8.2 Subsurface Soils Figure 4-10 (multiple figures) shows the final excavation soil depths with the chemical concentrations of each constituent at that depth. These figures also indicate the 90% UCL concentrations remaining at depth over the site, demonstrating that the remaining constituents in soil at the bottom of the excavation are below the ROD standards for subsurface soil for that constituent

4.4.8.3Groundwater After completion of the excavation andSite restoration aspects of the RA, a new monitoring well network was installed consisting of six (6) new monitoring wells (August 2008 - Figure 4-11) and two (2) existing wells on the Site property. Sampling results for this new monitoring well network indicated that the only significant exceedance of the ROD groundwater standards is in
one well (MW-16) for one constituent (Vernolate). These results are consistent with data

# m

collected from the prior monitoring well network before the soil excavation, although the Vernolate concentration inMW-16 wasconsiderably lower than previously measured.

Because of the detection of Vernolate in MW-16 (on the northern portion of the property), the EPA requested that three (3) additional monitoring wells be installed on the down-gradient property north of the Site (March 2009). During the initial sampling event, Vernolate was not delected in any of the off-site wells. In December 2010, ajl of the monitoring wells except for MW-16 and the off-site wells were abandoned in place in accordance with the previously mentioned Alabama requirements. In August 2012, the last groundwater monitoring event was conducted for MW-16 and the three off-site monitoring wells with all wells noh-detect for Vemolate. More details are provided regarding the groundwater monitoring program in Section 6.0.

4.4.9 Government Oversite The EPA retained TechLaw of Atlanta GA to provide government field oversite for the TLM soils excavatioh portion of the RA. The TechLaw representative worked closely with the OAR and the contractor to facilitate timely quality assurance and field decisions for excavation, backfill, and off-site disposal. TechLaw was the main liaison between the field and the EPA and also reviewed andprovided comments onthe RAWP.

4.4.10 Quality Assurance Contractor Quality Assurance and Management were provided by NewFields of Atlanta, Georgia. NewFields, as the OAR, maintained a presence on the Site during the RA from mobilization until demobilizationwas completed.

4.4.10.1 Construction Inspection NewFields inspected and directed all aspects of the work including excavation location and extent, staging locations and soil pile maintenance/covering, off-site disposal direction and approval coordination, backfill coordination and approval. Site restoration and other activities leading tothe successful completionof the excavationprogram.
