Final FONSI and EA for hot cargo pad on Kirtland AFB - Kirtland Air ...

<strong>Final</strong> <strong>EA</strong> Addressing Construction, Operation, <strong>and</strong> Maintenance of a Hot Cargo Pad
The area disturbed would overlap with soil vapor monitoring well (MW) KAFB-2604, <strong>and</strong> could also
affect MW KAFB-2606. In addition, the construction would overlap with groundwater MW KAFB-2622
<strong>and</strong> MW KAFB-2602A (KAFB 2008e). These <strong>and</strong> other MWs around the periphery of the Proposed
Action footprint are Long Term Monitoring (LTM) wells <strong>for</strong> monitoring soil vapor <strong>and</strong> groundwater
components of the WP-26. Presently, WP-26 is in the remedial investigation phase. During the
construction of the proposed <strong>hot</strong> <strong>cargo</strong> <strong>pad</strong>, BMPs should be followed to avoid damage to the existing
MWs. Additional MWs may need to be installed in the future. These MWs would require continued use,
which could also require surface modification (i.e., modification to flush-covering).
The NMED concurs that the removal of the surface sewage sludge would alleviate any potential adverse
effects on the environment <strong>and</strong> human health from soil contamination (Bitner 2009). Additionally, the
Proposed Action includes setting the existing MWs flush with the paving of the proposed <strong>hot</strong> <strong>cargo</strong> <strong>pad</strong>.
This would allow <strong>for</strong> the continued use of the MWs to aid in the remediation of the soil vapor <strong>and</strong> ground
water contamination, once appropriate remedial actions <strong>for</strong> these areas are selected. Consequently,
construction activities at Kirtl<strong>and</strong> AFB would result in impacts on the ERP site; however, these impacts
would be expected to be less than significant.
No significant impacts on ERP site WP-26 would be expected from the operation <strong>and</strong> maintenance of the
proposed <strong>hot</strong> <strong>cargo</strong> <strong>pad</strong>. While a remedial action has not been selected <strong>for</strong> the soil vapor <strong>and</strong> perched
groundwater contamination identified in the RFI, the samples with the highest identified levels of
contaminants were at the perched groundwater interface at approximately 200 feet bgs (KAFB 2008e). It
is likely that the approved remedial action will require periodic access to the area <strong>for</strong> collection of media
samples from the MWs. In addition, because the final remedial abatement has not been selected,
additional surface equipment, such as soil vapor extraction blowers/piping, might need to be installed.
While it is anticipated that interference with the proposed <strong>hot</strong> <strong>cargo</strong> <strong>pad</strong> would be minimal <strong>and</strong> required
equipment installation would be designed to operate from remote locations, some overlap might occur.
No significant impacts associated with the four MMRP sites would be expected during construction or
operational activities under the Proposed Action. Use of the four historic ranges identified in the Kirtl<strong>and</strong>
AFB MMRP that overlap with the proposed <strong>hot</strong> <strong>cargo</strong> <strong>pad</strong> site was discontinued prior to 1962, <strong>and</strong> the
Proposed Action area has undergone significant alteration in the intervening years. It is unlikely that
quantities of MC <strong>and</strong> MECs, if any, would be encountered during construction.
Asbestos-Containing Material. The construction, operation, <strong>and</strong> maintenance of the proposed <strong>hot</strong> <strong>cargo</strong>
<strong>pad</strong> would not involve the h<strong>and</strong>ling of ACMs; there<strong>for</strong>e, the Proposed Action would not result in any
impacts related to ACMs.
Lead-Based Paint. The construction, operation, <strong>and</strong> maintenance of the proposed <strong>hot</strong> <strong>cargo</strong> <strong>pad</strong> would
not involve the use of LBP; there<strong>for</strong>e, the Proposed Action would not result in any impacts related to
LBP.
Polychlorinated Biphenyls. The construction, operation, <strong>and</strong> maintenance of the proposed <strong>hot</strong> <strong>cargo</strong> <strong>pad</strong>
would not involve the h<strong>and</strong>ling of materials containing PCBs; there<strong>for</strong>e, the Proposed Action would not
result in any impacts related to PCBs.
Pollution Prevention. Less-than-significant impacts on the Pollution Prevention Program at Kirtl<strong>and</strong>
AFB would be expected from implementation of the Proposed Action. An incremental increase in
hazardous materials <strong>and</strong> wastes would be expected during construction <strong>and</strong> operation under the Proposed
Action. Adherence to the Pollution Prevention Program <strong>and</strong> associated plans at Kirtl<strong>and</strong> AFB, in
particular the Hazardous Material Emergency Planning <strong>and</strong> Response Plan, would reduce adverse impacts
