(BJ’s), Stantec is pleased to provide this summary of environmental and safety features associated with the proposed retail fueling facility in Carmel, IN. All fuel system devices and procedures are designed in accordance with State and Federal requirements to protect the environment, community, customers and employees. Proposed Facility BJ’s is proposing to install a new retail fueling facility on a portion of the lot adjacent to the BJ’s Wholesale Club store located in Greyhound Commons. The proposed fueling facility will consist of multiple fuel dispensers protected by an overhead canopy and supported by an attendant kiosk. The station is to be supplied by a total of three (3) double-wall fiberglass underground storage tanks storing gasoline and diesel. In accordance with the Indiana Department of Environmental Management (IDEM) and the US Environmental Protection Agency (USEPA), BJ’s maintains A/B/C Operators to oversee the fueling facility. These specialized staff are trained to operate the fuel system equipment, safety devices and support the operation of the facility. These same staff conduct daily inspections of the facility’s safety and environmental protection devices. Additionally, all BJ’s employees are trained in the proper use of an on-site emergency response kits as well as emergency procedures. 1 – Graphical Rendering of Gas Station Devices (included as attachment). January 5, 2023 Page 2 of 5 Reference: Proposed Retail Fueling Facility – Environmental and Safety FeaturesBJ’s Wholesale Club, Carmel, IN IDEM Environmental Protection and Safety The proposed fueling facility will be equipped with numerous environmental safety features which meet and/or exceed Indiana Department of Environmental Management (IDEM) requirements. These devices include, but are not limited to: • Redundant overfill protection devices on the tanks consisting of high level alarms and overflow prevention valves. • Double walled fill containment boxes and double walled vapor recovery boxes; • Electronic leak detection systems; • Double walled continuously monitored tanks and piping; • Additional systems described below. The entire system is monitored 24 hours a day by an electronic environmental monitoring system which tracks fuel levels, any liquid level changes, introduction of water, or any unusual operating conditions. Each fuel system component is UL listed in accordance with State and Federal requirements. All underground piping, tanks and related components are corrosion resistant. Added Tertiary Containment In addition to meeting IDEM requirements for underground fuel storage secondary containment, corrosion protection and environmental monitoring, BJs proposes to provide an added level of containment around (and under) the entire fuel storage and piping system by installing an impermeable liner. This proposed liner exceeds IDEM requirements for containment. This liner system ensures that the entire double walled fuel tanks/piping will have an added layer of environmental protection to the sub-grade. The proposed product will be “Petrogard” by MPC Containment or approved equal. This system is the same as those used by the US military and bulk storage facilities as a form of containment. 2 – Example image of liner being installed around and under double wall piping, providing tertiary containment for the fuel storage and distribution system. January 5, 2023 Page 3 of 5 Reference: Proposed Retail Fueling Facility – Environmental and Safety FeaturesBJ’s Wholesale Club, Carmel, IN Added Positive Limiting Barrier All proposed customer fuel transfer activities will take place over impermeable concrete surfaces to prevent any incidental fuel drips from entering the sub-grade. BJ’s is proposing to employ an added unique containment system in these dispensing areas which provides environmental protection by means of a “positive limiting barrier” or PLB. While this system is not yet an IDEM requirement, it is a best management practice, adopted by many states, which provides added protection against potential stormwater runoff at the dispensing area by preventing site runoff from mixing with those areas around the fuel dispenser. 3 – Photo example of Positive Limiting Barrier (stormwater BMP and containment) at dispensing area. 4 – Example Photo of Positive Limiting Barrier surrounding perimeter of concrete fuel dispensing apron. January 5, 2023 Page 4 of 5 Reference: Proposed Retail Fueling Facility – Environmental and Safety FeaturesBJ’s Wholesale Club, Carmel, IN In addition to the PLB, all fuel dispenser hoses are equipped with breakaway valves and the dispenser cabinets are equipped with shear valves to protect in the event of impact or a “drive off”. These safety devices shut off and “close” the fuel lines to prevent any spills in the event of a “drive off”. Added Air Quality Protection – Low Permeation Hoses Although not required by IDEM, BJ’s installs “Low Perm” dispensing hoses as an added air quality protection measure. These hoses are designed for use at filling stations to reduce vapor permeation rates, improve air quality and reduce emissions. BJ’s understands that air pollution and quality is a concern and is committed to this by installing a complete CARB (California Air Resources Board) EVR (Enhanced Vapor Recovery) system which ensures that all gas station system components are approved for the control of gasoline vapor emissions during the filling procedure for the underground storage tank system. 5 – Photo example of Continental Futura “Low Perm” hoses installed at a BJ’s Gas Station to provide added air quality protection. January 5, 2023 Page 5 of 5 Reference: Proposed Retail Fueling Facility – Environmental and Safety FeaturesBJ’s Wholesale Club, Carmel, IN Summary BJ’s is committed to provide an environmentally safe fuel facility which protects the environment, community and customers. As noted above, they are proposing to install several added protection devices, many which exceed IDEM standards. These include: • The impermeable liner under the entire double walled fuel system giving it three layers of protection; • The positive limiting barrier (PLB) which provide added stormwater protection; • “Low Perm” hoses which provide added air quality protection. • CARB (California Air Resources Board) EVR (Enhanced Vapor Recovery) system for the control of gas station emissions from underground storage tanks. • Redundant overfill protection and spill prevention measures. • Additional emergency shutoff devices located inside and outside of the kiosk. • 24 hour monitoring of all operations with security cameras throughout the facility.
