Comment 1 The proposed action is within the scope of CA TEX #8: Routine repair and maintenance of buildings, facilities, vessels, aircraft, and equipment associated with existing operations and activities. None of the exclusions from reliance on a CA TEX applies in this case; therefore, the proposed action is excluded from the requirement for further NEPA analysis.

!The applicability of this CATEX determination is based on the full implementation of all environmental requirements identified below.

Requir 1 Work may occur in the coastal zone; however, a Coastal Consistency Determination is not required provided that no deleterious material enters storm drains manholes, or the Thames River.

Requir2 883 was assessed for historic significance and determined to be eligible for listing on the National Register of Historic Places as part of the Dealey Center historic district. Contact the PWD EV Division Cultural Resource Manager (x5164 before conductin!l anv work at B83.

Requir 3 Work may occur in or near an IR zone/site. No ground-disturbing activities are planned; therefore, soil management procedures are not listed. If ground-disturbing activities are required, soil management procedures will be identified in an aooroved di!l permit issued by the PWD.

Requir4 Any regulated waste generated under the scope of this project shall be managed, stored, and disposed of in accordance with the SUBASENLON Hazardous Waste Mana□ement Plan.
