PRE-FIELD WORK ACTIVITIES <br /> Health and Safety Plan <br /> Field work performed by Delta and its subcontractors at the site is conducted according to guidelines <br /> established in a Site Health and Safety Plan(SHSP). The SHSP is a document that describes the hazards that <br /> may be encountered in the field and specifies protective equipment, work procedures and emergency <br /> information. A copy of the SHSP is at the site and is available for reference by appropriate parties during <br /> work at the site. <br /> Locating Underground Utilities <br /> Prior to commencement of any work that is to be below surface grade,the location of the excavation,boring, <br /> etc. is marked with white paint as required by law. An underground locating service such as Underground <br /> Service Alert (USA) is contacted. The locating company contacts the owners of the various utilities in the <br /> vicinity of the site to mark the locations of their underground utilities. A private locator may also be <br /> contacted for a private independent clearance. Any invasive work is preceded by hand auguring to a <br /> minimum depth of five feet below surface grade to avoid contact with underground utilities. <br /> FIELD METHODS AND PROCEDURES <br /> Soil Borings <br /> A Delta Environmental Consultants, Inc. geologist continuously logs (if required) each borehole according <br /> to the Soil Classification Method section during drilling and checks drill cuttings for indications of first <br /> recognizable occurrence of ground water and volatile hydrocarbons using either a portable photoionization <br /> detector or flame ionization detector. <br /> 1 <br />
