South Yarmouth Zone B3/APD Persons Present: Lt Michael Oliva Bill Ciocca Joe Carroll Barry Lewis Brendan Maloney Mark Grylls Gary St, Fleur Kathy Williams LUKe Poiner Amanda Lima Luke White Replacement of LNG Tank storing up to 2.1 million gallons liquified natural gas. Refer to Exhibits 2 through 10 for additional detail. Building: Project as proposed will require relief from the ZBA in the form of a SP for the use in the B3 and APO overlay. The height of the tank was referenced in discussion will likely require a variance. Original project was provided an exemption from the zoning bylaws in Jan. 1969 through decision #15972 and modified in Nov.1971 through decisions 15972A and 15972B. These decisions were specific to the existing conditions, which is the reason for the relief from the local ZBA. Having no prior relief from the ZBA, there are no existing decisions of the board to modify. Building permits required to demolish and construct new tank. Stormwater Management permit will be required from the Conservation Commission. Plannina: For the ZBA, clearly outline the reasons explained at SPR for the needed height (88'), new tank location, clearing limits and tank containment within the new tank. Consider other locations for visualizations along the CCRT and Beacon Street neighborhood. Maximum 20' site lighting pole height, and footcandle requirements at property lines, per Section 301.4.10. Design Review: Not present. Conservation: The proposed project requires a stormwater management permit. Engineerina: • Provide drainage calculations when available to review upon submission of Stormwater Management permit. Provide vapor fence detail • Confirm purpose of the fire access path on the exterior side of the fence. Provide truck turning movements on the site plan • Site plan appears to reflect the southwest part of the path just ends of vegetation and fire trucks exiting from the southwest side of the fire access path would have no way to exit (traveling clockwise). Please confirm the vehicle flow intent. • Confirm what restoration will look like upon decommissioning of LNG tank • Provide height and diameter of the existing and new tanks. Fire: hotwork requires permit. Fire watch personnel shall be assigned as needed by NG and the AHJ to determined by Health: (Hazardous Materials) New LNG Tank What is construction material of the 2.1-million-gallon full containment LNG storage tank? Does the LNG storage tank have a double wall to provide insulation? Does the double wall also serve as secondary containment in the event of a leak in the inner tank? Does the LNG tank have an interstitial leak detection system between the inner and outer tank walls? Moats and Trenches Will the new LNG tank be surrounded by a moat? If a moat is used, what is constructed from or lined with? What are the trenches from the tank to the impound area constructed from or lined with? If the new LNG tank is not surrounded by a moat, how would a leak be directed to the trenches leading to the impound areas? Pi in Is the LNG piping to the tank double -walled? Does LNG piping to the tank have a leak detection system? Is the LNG send out piping from the new tank double -walled? Does the LNG send out piping from the new tank have a leak detection system? Is all LNG piping aboveground? I understand from the National Grid NFPA 59A Fire Protection Evaluation, section 3.8.1 LNG and Liquid Nitrogen Spill Control, that all areas beneath LNG equipment and piping are curbed and graded to route any spills away from the equipment and into trenches that drain into local impoundment basins. Liquid Nitrogen What is the capacity of the liquid nitrogen storage vessel? What is the capacity of the area surrounded by the concrete curb around the nitrogen equipment? Impound Areas What are the capacities of LNG impoundment basins S-6100 and S-6200? From what material are the impound areas constructed or lined with? LNG Release In the event of an LNG release, would all liquid material be contained by or vaporize from, the impoundment basins without escaping to the environment and potentially impacting ground water? Water: Confirm the tie in of water main on east side of Whites Path. Also coordinate with vendor when the time comes to fill the tank with 1 m gal.
