Iliff Aurora, CO 80014 (303) 752-4683 January 13, 1988 Mr. Rick Hattman Gefroh & Hattman, Inc. 135 W. Swallow Rd. Fort Collins, CO. 80525 RE: PDQ Gasoline Systems Dear Rick: - --.- - 7 -- 15 oil Enclosed, please find materials on PDQ's standard gasoline storage and dispensing system. Please contact me with questions or further requests. Since/rely Mark B. Nelson Real Estate Representative PDQ Food Stores of Colorado, Inc. PDQ uses the latest technology in gasoline storage and delivery systems. Underground tanks and all piping to the dispensers are made from 100% corrosion free high grade fiberglass approved by Underwriters Laboratory. All tanks are enveloped with a minimum one foot layer of 3/8" pea gravel to provide a cushion of protection. We go beyond the industry standards and install flexible pipe joints where the fiberglass pines are connected to the tanks and dispenser to protect against c 5age due to excessive soil expansion and contraction. Such a ._,tem can remain operative in the ground for an indefinite period of time. The local Fire Department oversees the installation of such facilities with inspections before and after the tanks are placed in the ground, in addition to the initial approval given by the State Oil and Gas Inspection Department upon plan review. A geotechnical engineering study is done for each site to identify soil types, properties and moisture presence. Should groundwater be excessive, the tanks are anchored either from the bottom with cables fastened to concrete blocks or a concrete slab or from above with a thickened coverslab to prevent movement due to the tanks buoyancy. PDQ incorporates six different safety measures to safeguard against loss of product. 1. There is an emergency shut off switch located at the gasoline console by the cash register which allows the clerk to shut down the entire pumping system instantaneously. 2. All dispensers are equipped with a special shut off valve located just below the concrete pump island, which closes automatically should the dispenser be run into or completely torn off the island. 3. Each gasoline pump is equipped with a leak detector. This devise senses the flow rate in the lines between the tanks and dispensers. Should the pressure increase at any time, at a rate faster than the dispensers are known to operate, the valve shuts off the flow of gas at the pump. 4. PDQ equips each tank with a computerized tank level sensor. This system continuously monitors gasoline volume, temperature, and reports any water presence within the tanks, with a detailed printout. The store manager daily correlates actual sales with the computerized printouts to monitor gasoline inventory. Small losses of product can be spotted quickly. in addition, the system is programmed to complete a tank tightness test every night to insure that no gasoline is leaking. 5. Weekly, our Managers are required to manually measure the amount of product in each fuel storage tank and send a weekly report to our corporate office for comparison with daily logs showing the amount of fuel sold at the cash registers. 6. During construction, PDQ installs several observation wells in the tank hole. The wells consist of a four inch perforated pipe extending to the bottom of the tank hole, a minimum of 12 feet. Should product loss occur, any lost fuel will quickly flow through the porous pea gravel to the slightly depressed location of the observation well where it can be discovered, measured and pumped from the tank hole if necessary. PDQ shares the communities concerns for the operation of a safe gasoline facility. We have incorporated many safety devices which are considered the very best in the industry. We believe that an understanding of the safety precautions and devices used by PDQ will alleviate any safety concerns which may exist.
