ADDITIONAL REQUIREMENTS or COMMENTS Comment 1 The proposed action is within the scope of CATEX #8: Routine repair and maintenance of buildings, facilities, vessels, aircraft, ranges, and equipment associated with existing operations and activities.

None of the exclusions from reliance on a CATEX applies in this case; therefore, the proposed action does not require further NEPA analysis. The applicability of this CATEX determination requires full implementation of all environmental requirements identified below.

Comment 2 Work at B77 occurs in the coastal zone; however, a Coastal Consistency Determination is not required because the project scope does not include activities identified on CT DEEP's list of federal activities subject to consistency review, as established in the CT Coastal Management Plan. In addition, the project does not have the potential to significantly affect state coastal resources and/or uses.

Requir 1 Work shall comply with all Federal, State, and local environmental regulations as well as with all applicable Navy requirements. SUBASENLON PWD EV shall be the point of contact for all questions related to environmental rules or regulations.

Requir 2 Work may occur in areas located in or near an IR zone/site. However, no ground-disturbing activities are included in the scope of work. If ground-disturbing activities are planned, a dig permit shall be obtained prior to the initiation of such activity and soil management procedures detailed in the dig permit and the SUBASE Soil Management SOP shall be followed.

Requir 3 Use of exterior storage and laydown areas in support of this project shall be done in compliance with SUBASENLON instructions and policies. Site must be evident of good housekeeping practices consistent with proper storm water management and control.

Requir 4 The SUBASENLON Fire Department (860-694-3333) shall be notified immediately of any spill to the environment.

Spills shall also be reported in accordance with federal, state, and Navy spill reporting requirements and with the latest procedures enforced by SUBASENLON and the PW NLON EV Division. Clean-up actions are the responsibility of the contractor. If reporting to the State or the NRC is required, the contractor is responsible for completing verbal and written notifications. Copies of any CT DEEP- or NRC-required spill reports shall be submitted to the PW NLON EV Division within 24 hours of any spill.

Requir 5 SDSs for new products used and installed under the project shall be forwarded to the PW NLON EV Division in support of EPCRA Programs.

Requir 6 A list of HAZMAT scheduled for use or installation on the project and the approximate quantities/volumes of these materials shall be submitted to the PW NLON EV Division EPCRA Manager (x5140) prior to initiating project activities.

Requir 7 All storage tanks holding petroleum products, >55 gallons, must meet the requirements of 40 CFR 112, NFPA 20, 30, 30A, and 31. Tank specifications shall be provided to the PW NLON EV Division Tank Program Manager (x5133) prior to installation.

Requir 8 Any work activities impacting buildings eligible for listing on the National Register of Historic Places shall be subject to consultation with the State Historic Preservation Office (SHPO), which shall be coordinated through the PW NLON EV Division Cultural Resource Manager (x5649). Advance notice is required for projects in the following buildings/areas: B83, B84, B86, B141, B164, B168, B169, B439, and Dealey Plaza.

Requir 9 Contractor is required to pack and take with any incidental regulated waste generated while servicing (oily rags, paint brushes, parts change-out, etc). This does NOT get disposed of on base.

Requir 10 The manufacturer’s VOC data sheet(s) and SDS sheet(s) for any adhesives or coatings shall be provided to the PW NLON EV Division Air Program Manager (860-694-5192) for verification that the VOC content is within established CT Architectural, Industrial and Maintenance (AIM) limits and to the PW NLON EV Division EPCRA Manager (860-694- 5140).

Requir 11 Requirements associated with the PW NLON EV Division Air and Tank Programs were written into the original contract. The renewal contract shall be submitted to the PW NLON EV Division for review to ensure that existing requirements remain and that new requirements are added.
