Recommended Conditions of Approval February 20, 2014 <br />PLN2013-00045; 1333 Martinez Street Page 6 of 20 <br /> Pre-Construction Planning and Notification: Prior to the start of construction <br />activities involving below-ground work, information regarding known areas of <br />contamination shall be provided to the contractor by the Site owner. <br /> Site-Specific Health and Safety Worker Requirements: Each contractor will be <br />responsible for the health and safety of their own workers, including, but not <br />limited to, preparation of their own health and safety plan (HSP) and injury and <br />illness prevention plan (IIPP). The purpose of these documents is to provide <br />general guidance to the work hazards that may be encountered during each phase <br />of construction activities <br /> Contractors are also required to determine the requirements for worker training, <br />based on the level of expected contact to soil, soil vapor, and groundwater <br />associated with the contractor’s activities and locations. The HSP shall contain <br />provisions for limiting and monitoring chemical exposure to construction <br />workers, chemical and non-chemical hazards, emergency procedures, and standard <br />safety protocols. Depending upon known conditions at the time of site <br />development, employees conducting earthwork activities at the Site may be <br />required to complete a 40-hour HAZWOPER training course (29 CFR 1910.120 <br />(e)), including respirator and personal protective equipment training. <br /> Construction Impact Mitigation Measures: During construction, measures shall be <br />taken by contractors to minimize dust generation, storm water runoff and tracking <br />of soil off the Sites. In addition, measures will be taken to reduce the potential for <br />the creation of preferential pathways (vertical or horizontal) for COPCs detected <br />at the Sites during the planned subsurface investigations of soil, soil gas and/or <br />groundwater beneath the Sites. Construction impact mitigation measures are <br />described below. <br /> Site Control: Site control procedures shall be implemented to control the flow of <br />personnel, vehicles and materials in and out of the Sites while working in known <br />contaminated areas. (Currently, there are no known contaminated areas.) The <br />control measures described below will help control the spread of COPCs. <br /> The perimeter of the sites shall be fenced. Access and egress shall be controlled <br />at the appropriate locations. Signs will be posted instructing visitors to sign in at <br />the project support areas at all site entrances. <br /> Equipment Decontamination: Contractors whose vehicles and construction <br />equipment contact soil that is suspected of being contaminated shall be required to <br />clean the equipment upon leaving the contaminated area. A decontamination area <br />will be established near the construction exit of each area. Soil will be removed <br />from the equipment and vehicles before leaving the contaminated area. Cleaning <br />methods used may include dry methods, such as brushing, scraping, or <br />vacuuming. If dry methods are not effective, wet methods, such as steam cleaning <br />or pressure-washing, should be used. The contractor will contain, manage, and <br />collect samples of the rinse water for analytical testing by a state certified <br />laboratory prior to appropriate disposal. Decontamination procedures shall be <br />developed and implemented by the construction contractor to minimize the <br />possibility that equipment releases contaminated soil onto public roadways or to <br />on-Site areas containing “clean” cover materials or new paving. <br /> Personal Protective Equipment: Personal Protective Equipment (PPE) and <br />clothing shall be used to isolate workers from COPCs and physical hazards.
