In July 1993, the BRAC Commission recommended closure of<br />
the Dallas Naval Air Station (NAS), which served as a pilot<br />
training center. The installation closed September 30, 1998.<br />
After the base was closed, operations were transferred to Fort<br />
Worth NAS. A number of the industrial operations that<br />
supported the installation's military mission contributed to<br />
contamination. For investigation of environmental conditions,<br />
the installation was divided into six areas, categories A through<br />
F, based on operations and property ownership. In FY94, a<br />
BRAC cleanup team (BCT) was formed, and a BRAC cleanup<br />
plan was completed. The installation formed a Restoration<br />
Advisory Board (RAB), which was adjourned in FY05, and<br />
established an information repository. A local redevelopment<br />
authority was established and adopted a land reuse plan.<br />
During FY96, the installation completed a community relations<br />
plan.<br />
The installation completed a RCRA facility assessment, which<br />
identified 139 solid waste management units (SWMUs) and 44<br />
areas of concern. To date, 47 sites have been identified at this<br />
installation requiring further action. The cleanup progress at<br />
Dallas NAS for FY02 through FY05 is detailed below.<br />
In FY02, the installation continued monitoring and one pilot<br />
study to address compounds in groundwater. Negotiations with<br />
the City of Dallas regarding cleanup standards and activities<br />
were settled. The Navy completed an inventory of all Military<br />
Munitions Response Program (MMRP) sites. Two MMRP sites<br />
were identified at this installation. One site was determined to<br />
require no further action through the RCRA facility investigation<br />
process.<br />
In FY03, interim actions at one groundwater site continued. The<br />
rubble landfill and the Texas Air National Guard pond<br />
sediments were excavated and disposed of at an off-site<br />
landfill. Dallas NAS excavated soil across the installation that<br />
exceeded state closure criteria and disposed of it off-site as<br />
part of the source removal actions. The installation continued<br />
long-term management (LTM) of the remedy for the main fuel<br />
farm and conducted negotiations with the regulatory agencies<br />
to accept monitored natural attenuation (MNA) as the preferred<br />
remedy for groundwater contaminants. A RCRA permit renewal<br />
and compliance plan application were completed for the<br />
Navy<br />

remaining groundwater plumes. The second MMRP site was<br />
remediated in conjunction with the excavation and disposal<br />
activity at the Rubble Landfill. The BCT conducted team<br />
meetings and various site visits of ongoing remediation.<br />
In FY04, the installation completed soil remediation, and<br />
continued MNA on groundwater plumes. The installation also<br />
implemented enhanced MNA pilot studies. Dallas NAS initiated<br />
BCT review of closure documents and final regulatory approval.<br />
In FY05, the installation continued investigation and MNA on<br />
the groundwater plumes. The installation submitted final<br />
response action plans. In addition, the installation completed<br />
response action completion reports for 84 soil sites and<br />
submitted them for review. Long-term operation (LTO)/LTM<br />
continued for the remaining sites. The RAB adjourned, due to<br />
the specified environmental cleanup standards and funding<br />
provided in the settlement agreement between the City of<br />
Dallas and the Navy.<br />

Dallas NAS completed site restoration and groundwater<br />
excavation at SWMUs 18 and 85 by engineering maintenance<br />
and control. The installation continued LTO/LTM for remaining<br />
sites. The Navy completed MNA remediation at SWMU 35 and<br />
began the report.<br />
