0 0 KENNEDY/JENKS CONSULTANTS STANDARD OPERATING PROCEDURES INVASIVE ACTIVITIES — UTILITY LOCATION PROCEDURES Below is a summary of the minimum requirements for location of potential underground utilities where invasive activities are planned. Invasive activities include, but are not limited to, drilling soil borings, installing wells, hand-auger borings, excavating test pits, remedial injections, and other similar activities which penetrate the ground surface. Minimum Procedures (Non-BNSF Sites or BNSF Off-property Sites) 1. Contact the client or property owner where invasive activities will be performed to inquire about possible underground utilities and request maps or drawings documenting the location of the utilities. Document your request for information (e.g., written email request for information). 2. Contact the local/regional underground utility location center to document planned activities and request all underground utilities be located. In most(if not all) US states, this can be initiated by dialing "811". Contacting the local underground utility center is also required by state law. Contacting the local utility location center is required for each episode (event) of invasive work. It is preferred to arrange a field meeting with utility representatives to confirm the absence of utilities at each drilling location. Maintain a written record for each boring/invasive location and get signatures from the locators documenting the locations are clear of utilities. This can be performed on a site map or KJ's Utility Locate Form &Acknowledgment Form(provided in the KJ Safety Zone). The goal is to have written acknowledgement that all final drilling locations are free of underground utilities. 3. At all locations where drilling, probing or well installation will be performed, an air- knife or similar form of suction pot-holing will be performed to assess possible underground utilities in the upper 6 to 8 feet of soils (depending on local conditions and expected depth of utilities). Potholing is required at all drilling locations, except in remote areas where the likelihood of encountering underground utilities is very low and only as approved by a Risk Manager, Resource Manager or Officer of the company familiar with underground utilities. (Note: Use of an air knife will be appropriate for most invasive drilling and probing work, but may not be appropriate for certain activities like very shallow borings (less than 1-foot deep), certain hand-auger borings, remedial injections using probe equipment and test pitting.) Case by case exceptions for activities may be provided. Optional Step—While it is recommended under most conditions, an optional additional step includes coordinating (including establishing a written contract)with a private utility locator to perform an independent utility evaluation to locate "all underground utilities"at the proposed locations of invasive work. Maintain written record for each boring/invasive location and get signatures from the locators. [Note: This step is typically not too expensive and can save costs incurred during suction pot-holing by focusing the areas of the borings (i.e., provides prior knowledge of possible utilities).] Page 11 11 February 2015
