California 95351 <br /> 209-579-2221 <br /> (M%TC Fax: 209-579-2222 <br /> AS SOC IATES I N C . <br /> March 24, 2010 <br /> Traffic Control Plan <br /> Periodic Ozone Injection <br /> Sidewalk Right-of-Way <br /> 4100 E. Main Street <br /> Stockton, California <br /> The purpose of this Traffic Control Plan is to provide guidelines to protect ATC Associates Inc. <br /> (ATC) employees and contractors during the injection of ozone into the groundwater via the <br /> existing monitoring wells located in the sidewalk and the southern-most traffic lane, in the <br /> southern right-of-way, of East Main Street in Stockton; California (Figure 1). <br /> The work zone is defined as the area extending east of the intersection E. Main and of Oro <br /> Avenue along the south side of the eastbound lanes of East Main Street in front of 4100 East <br /> Main Street. A schematic of the traffic control plan is shown on the attached figure (Figure 2). <br /> East Main Street is located in a commercial district and has a speed limit of 35 miles per hour in <br /> this location. <br /> These injections are part of a state-mandated groundwater degradation investigation and <br /> remediation project that resulted from a gasoline release from an underground storage tank <br /> system from the Jamar Service Station located at 4075 East Main Street, Stockton, California. <br /> This project is being overseen by the San Joaquin County Environmental Health Department. <br /> ATC will be providing oversight of this work. <br /> Traffic Plan <br /> Proper PPE will be worn during traffic operations, which includes a highly visible traffic-rated <br /> safety vest, a hard hat and steel-toed boots. An unoccupied work vehicle will be placed in the <br /> southern most eastbound lane of East Main Street between the work zone and oncoming traffic. <br /> The vehicle will be positioned with some room between the rear of the vehicle and the work <br /> zone. The work vehicle will be positioned facing oncoming traffic, with its headlights on (day or <br /> night), parking brake engaged and wheels turned so that if it was struck, it will turn away from <br /> the worksite. The truck will also be outfitted with an amber flashing warning beacon atop its cab. <br /> The positioned vehicle will function as a visible warning sign, but should an oncoming car fail to <br /> yield; the vehicle also will absorb the first impact of a crash and will shield occupants of the <br /> worksite. <br /> Use of Signs and Cones to Direct Traffic. Traffic signs and cones will be used to direct traffic <br /> away from the work zone. Cones and signs will be placed a sufficient distance ahead of the <br /> work zone to provide oncoming drivers enough time to react and provide clear indications of the <br /> intended traffic flow. <br /> Traffic Cones: <br /> Traffic cones will be placed within the southern most eastbound lane of East Main Street <br /> (oncoming traffic side) at a maximum of 100 feet west of the work zone and 40 feet east of the <br /> work zone. Cones placed In between the taDered zones will be spaced at a maximum interval of <br /> 50 feet. <br /> Traffic Control Plan 1 ATC Associates, Inc. <br /> Periodic Ozone Injection <br /> 4100 E.
