PMY <br /> c) Is it possible to dispose of the cuttings on the site (i.e., are there any areas to spread the dirt without <br /> impacting property use or appearance)? <br /> d) At sites where impact is unknown but unlikely, and no field indication of impact is observed while <br /> sampling, it can be acceptable to place the soil back into the boring or test pit from where it was <br /> produced. This is only allowed if the client, regulatory community, landowner, etc., is aware and has <br /> approved this method. <br /> 2.2 Options <br /> The options should be evaluated prior to field work with respect to cost and ability to store the cuttings at <br /> the site. The options for handling of soil cuttings include: <br /> a) Consider using a Geoprobe sampling system or equivalent,which generates minimal soil cuttings. <br /> b) Under some circumstances, soil cuttings or excavation spoils can be spread on the site or used to <br /> backfill borings or test pits form where they were produced. <br /> c) Use 55-gallon steel drums or equivalent, equipped with lids. <br /> d) Obtain a roll-off bin for use at the site (lined or unlined depending on waste media). <br /> 2.3 Field Procedures <br /> The following procedures and considerations will be used in the field: <br /> a) Cuttings spread on site should be placed in an area that is not paved. The cuttings should be spread <br /> in a manner to minimize visual impact, and which will not impact site use. Consult with the owner or <br /> occupant of the property for a suitable location. <br /> b) Always place drums in an area that will not impact the use of the property. Always notify the owner <br /> that drums have been stored on the site and explain the process and schedule for evaluating disposal <br /> options. If the owner or occupant of the site is available, question them as to the best place to store <br /> the drums. <br /> c) The lids of the drums should be secured prior to leaving the site. <br /> d) The drums should be checked for rusting at the base and should not have large dents that could affect <br /> the performance of the drum. <br /> e) The drums will be placed on a wooden pallet to prevent the bottom of the steel drum from rusting. <br /> f) The drums should be labeled, using a permanent paint marker or a drum label sticker, with the <br /> following information: <br /> i) "Pinyon Environmental - 303-980-5200" <br /> ii) 'Investigation Derived Soil Cuttings" <br /> iii) Include the date of drilling activities <br /> iv) Include the boring numbers, specific to that drum <br /> v) Include the project number <br /> g) Drums cannot be transported off-site unless analytical data is received. In the case that the drums must <br /> be transported off-site without analytical data, the drums must be transported as hazardous waste. <br /> 2,4 Follow-Up <br /> The project manager will be responsible for the following activities: <br /> a) Upon receipt of analytical results, disposal options should be considered. Disposal options include: <br /> i) If contaminants are not detected in the soil, and the site is suitable, the cuttings can be spread on <br /> the site. <br /> IDW and Waste Materials Handling <br /> December 23, 2022 <br /> Page 2 of 7 <br />
