MASHPEE ZONING BOARD OF APPEALS January 26, 2011 • Minutes The Petitioner has received both Plan Review and Design Review Committee approval for the proposal. Mr. Nelson said that the landscaping also requires Design Review approval. The January 18, 2011 combined meeting of Design Review and Plan Review Committees and Minutes are attached to the Minutes. Mr. William S. Taber detailed the proposed environmental safety features. Plans require upgrading to the latest materials for gasoline fueling facilities. Some of the features include double -walled, non -corrosive, underground storage tanks with a brine -filled space with sensor monitors. The tanks have fiberglass containment solutions and have a 30 -year warranty. Double -walled, non -corrosive piping will also be installed. Continuous monitoring systems will be installed to monitor the sumps, the brine and the piping. Vapors displaced by the fuel tankers during filling will be diverted back into the tanker truck. Vapors displaced by fueling customers will be drawn back into the system. Overfill protection will prevent spillage from the tanker to the tanks. Spill containment manholes will collect any losses from the tanker hoses. Mr. Taber said that Massachusetts Law requires a self -serve station to have an attendant on site during all hours of operation. The system will not operate unless an attendant authorizes and activates the fuel dispensers. In addition, the fuel pumps have line leak detectors which sense any pressure loss and will shut down the dispenser pumps. Dispenser shear valves on the fuel pumps will close the line in the event of a fire or • impact. Dispenser hose break -away valves prevent vehicles from being driven away with a pump hose attached to the vehicle's gas tank. Dispenser sumps will have sensor monitors. Positive limiting barriers around each fuel pump dispenser are designed to contain as much as 10 gallons of spilled gasoline. Monitoring wells will be installed on both ends of the tank. Emergency shut -offs will be placed on each dispenser. There is a panic button next to the cash register inside the kiosk. A camera system will be installed to monitor all of the fuel pump locations. A fire -suppression system (both automatic and manual) inside the canopy will engage in the case of a fire. Mr. Taber said that a dry powder, silica -type material is used for fires. He said that the substance is inert, very sticky and coats everything and works very well. A spill response kit will be maintained on site. Mr. Taber said that in the event of spills greater than 10 gallons, the Mass. DEP and Fire Department must be notified within several hours. The DEP will also make an on-site visit to ensure clean up. Mr. Bonvie suggested that the Board should condition a regular maintenance program of the sump pump catch basins and hoods within the catch basins. Mr. Dowdy assured the Board that the owner is required to conduct ongoing maintenance of the sump pumps and catch basins. Mr. Nelson said that the Petitioner should receive Board of Selectmen approval before the ZBA can act if plans call for a change in the size of the tanks. Attorney Ford said that ZBA approval is contingent upon upgrading and meeting state requirements and that he • was advised to start with the ZBA. He said that the proposal will go to the Fire Marshall, the Fire Department and the Board of Selectmen only if the Petitioner gets approval from the Special Permit granting authority, the ZBA.
