Materials to be stored on site shall be limited to three grades of automotive fuel and diesel fuel. All materials shall be stored in underground tanks conforming to US EPA, NFPA 30, NFPA 30A and local code requirements. Adjacent land uses consist primarily of office and light, manufacturing facilities. Storm water shall be directed northeast on site and pass through a water quality structure before entering the Spring Creek drainage. The water quality structure shall be constructed as necessary to capture sediment and hydrocarbons suspended in the runoff. Delivery of materials to the site will most likely be from west bound Prospect Road to south bound Specht Point Road. Entry into the property shall be from a drive entrance between lots 1 and 7. Upon delivery of fuel, transport vehicles should attempt to use the same access drive for exiting from the site to north bound Specht Point Road then east bound Prospect Road. Mitigation of potential firelexplosion hazard shall be accomplished through the utilization of modern, state of the art storage and dispensing equipment conforming to EPA and NFPA requirements. Equipment shall include the following: - Water tight dispenser sumps with bulkhead fittingsat all penetrations. - Double poppet emergency shut-off valves at all dispensers. - Flexible product pipe equipped with UL rating. All joints and terminations shall be in water tight sumps. - Water tight sumps at all turbine pumps with bulkhead fittings at all penetrations. - Water tight spill containers at all tank fill points. Spill containers shall be designed to allow overflow from filling operations to be drained into tank. - Positive shut-off valves on tank fills. Shut-off shall be set to 95% of tank capacity. - Atmospheric vent to limit tank pressure below 0.5psig. - Underground storage tank monitoring system with capabilities of the following: Continuous inventory monitoring. - 0.1 gph leak detection. - Product line leak detection. - Interstitial and sump leak sensing. - Vapor well and groundwater monitoring. Emergency pump shut-off immediately available to trained convenience store personnel. Through the use of modern, state of the art fueling components the potential for an incident is greatly reduced. Possible.spills will be small and easily cleanable through the use of oil absorbing agents applied by store personnel. In the unlikely event a large spill should occur the site shall be graded such that surface drainage will be directed through an oil/water bmp separation device located to the northeast of the c-store. This separation device shall be constructed such that. hydrocarbons suspended in the water shall be removed prior to introduction into the Spring Creek drainage. Methods used may include oil absorbing booms or physical oil separation structures. Directing surface run-off to this area and through a cleansing device designed to separate hydrocarbons from water will reduce the probability of hazardous materials entering the Spring Creek drainage. Underground storage tanks shall be continuously monitored by electronic methods with manual monitoring at federally mandated intervals. Electronic monitors shall have the capability of monitoring the tanks inventory as well as product lines, observation wells and sumps. Through continuous monitoring a leak from the underground tanks should be easily recognized and addressed in a timely manner. Through the utilization of modem, state of the art fueling components, certified by Underwriters Laboratories (LJL) and conforming to EPA and NFPA specifications, the risk of a leak or spill is greatly reduced. Owner/operator of the store shall have on file an emergency action plan to address different scenarios and plans of action. All employees shall be knowledgeable of the action plan and equipped with the products and materials to carry out the plan. HAZARDOUS MATERIALS IMPACT ANALYSIS LOT 5 SPRING CREEK CENTER PUD Lot 5, Spring Creek Center PUD consists of the development of a convenience store, car wash and four (4) gasoline dispenser islands on 0.89 acres located at the northeast intersection of Timberline Road and Midpoint Drive. Materials to be stored on site shall be limited to three grades of automotive fuel and diesel fuel.. All materials shall be stored in underground tanks conforming to US EPA, NFPA 30, NFPA 30A and local code requirements. Adjacent land uses consist primarily of office and.light manufacturing facilities. Storm water shall be directed northeast on site and pass through a water quality structure before entering the Spring Creek drainage. The water quality structure shall be constructed as necessary to capture sediment and hydrocarbons suspended in the runoff. Delivery of materials to the site will most likely be from south bound Timberline Road to east bound Midpoint Drive. Entry into the property shall be from a drive entrance between lots 5 and 6. Upon delivery of fuel, transport vehicles should attempt to use the same access drive for exiting from the site to west bound Midpoint Drive then north bound Timberline Road. Mitigation of potential firelexplosion hazard shall be accomplished through the utilization of modem, state of the art storage and dispensing equipment conforming to EPA and NFPA requirements.

Possible spills will be small and easily cleanable through the use of oil absorbing agents applied by store personnel. In the unlikely event a large spill should occur the site shall be graded such that surface drainage will be directed through an oil/water bmp separation device located to the northeast of the fuel island canopy in the landscape area near the car wash drive -up lanes. This separation device shall be constructed such that hydrocarbons suspended in the water shall be removed prior to introduction into the Spring Creek drainage. Methods used may include oil absorbing booms or physical oil separation structures. Directing surface run-off to this area and through a cleansing device designed to separate hydrocarbons from water will reduce the probability of hazardous materials entering the Spring Creek drainage.
