GENERAL PROJECT INFORMATION

1 Activity Requesting: FEAD

2 Activity POC / Phone / email: Kalyani Baxi / 860 518 3491 / Kalyani.baxi@navy.mil

3 Name of Project: B571 Roof Replacement

4 Project Number (if any): 1655760

5 Project Location: B571 – Nautilus Museum and Library, Groton, CT

6 Project Type: Repair by Replacement

7 Description of the Project: The project replaces existing EPDM roof with modified bitumen roof.

If so indicate what type of waste(s) will be generated. Pressure washing is required by the manufacturer in advance of the roofing application in order to obtain the 20-year roofing warranty.

21 Will the construction / repair actions require de-watering from excavations, trenches or manholes? If yes, circle where de-watering will occur?

DESIGN RELATED QUESTIONS YES NO UNSURE

22 Will there be new hard pipe connections or modifications to existing hard pipe connections using water from Groton Utilities, the Thames, or wells?

Will new hard pipe connections or modifications to existing hard pipe connections discharge wastewater to the sanitary sewer, storm sewer or the Thames River? If so circle discharge type.

24 Will there be UST or AST installation, modification, or removal? If so indicate which type of tank and which action.

25 Will there be installation, repair, modification or removal of any system containing refrigerants

(e. g. freon, halon)?

26 Will there be modifications, destruction, or disturbance of the shoreline, streams, groundwater tables, surface water bodies, or wetlands? If so, explain.

Will there be any excavation and/or dewatering with the potential to impact the designated CT Coastal Zone (i.e., 1,000 feet inland from the MHW line)? If so, what type of activity will occur that can potentially impact the coastal zone area?

28 New proposed use and/or application of pesticides, rodenticides and herbicides? If so, indicate which type.

29 Will the project require pile driving?

OPERATIONAL RELATED QUESTIONS YES NO UNSURE

30 Will emission-generating equipment be installed (ex. paint booth, emergency generators)? If so, what type of equipment will be installed?

31 Will there be any new processes or maintenance activities conducted? If so, describe what they are.

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 is based on the full implementation of all environmental requirements identified below.

Comment 2 A Record of Non-Applicability was completed to document compliance with the General Conformity Rule, Section 176(c) of the Clean Air Act. The proposed action is exempt by rule per 40 CFR 93.153(iv).

Requir 1 Work at B571 occurs 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.

Requir 2 Historic assets are displayed and stored in B571 and are on exhibit on the museum grounds. Work activities shall not alter, damage, or negatively impact any historic assets.

Requir 3 Land use controls (LUCs) for soil and groundwater are in place adjacent to the museum (Site 8) and a landfill cap is present at Site 8. Work activities shall not disturb, damage, or otherwise affect the integrity of the cap.

Requir 4 B571 is 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.

Requir 5 The contractor shall obtain a permit to discharge wastewater from the CT Department of Energy & Environmental Protection prior to initiating power washing. PW NLON EV Division Wastewater Program Manager (x2525) shall be notified in advance of any planned discharges to ensure compliance with permit requirements.

Requir 6 The manufacturer’s VOC data sheet(s) and SDS sheet(s) for any coatings or adhesives shall be provided to the PW NLON EV Division Air Program Manager 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.

Requir 7 The PWD Asbestos Program Manager shall be contacted for past asbestos survey data for B571. Existing facility HAZMAT surveys shall be reviewed prior to any facility disturbance. If suspect hazardous materials (such as asbestos and lead paint) are present and are anticipated to be disturbed under the scope of the project, surveys shall be conducted by qualified individuals in advance of construction activity. All survey results shall be provided to the PW NLON EV Division.

Requir 8 Disposal of any regulated waste shall be coordinated in advance with the PW NLON Hazardous Waste Program Office (x4298).

- Non-regulated solid waste (i.e., general trash, construction debris, and recyclable items) shall be properly managed and disposed of in accordance with Federal, State, Navy, and local regulations.

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