Page 33 of 132

3.4.4 - Entering the Site

It is the responsibility of the owner or operator or the vehicle or rig to ensure that the drill site is safe to

enter and that it is safe to begin work. Such inspections often include the following:

• Are high voltage overhead power lines or any other utility lines present in the immediate area? A safe

distance of thirty or more feet laterally to either side of the overhead utility should be observed when

setting up in the vicinity of overhead lines. This distance may need to be adjusted, depending on the

hazards involved, size of mast on the drill rig, and other considerations.

• Have all underground utilities been identified?

• Is there a danger of being struck by other moving vehicles?

• Is there a danger because of possible instability of high walls, banks, pits, rivers, and other related

items?

• Are poisonous plants, animals, or insects in the area of the drill site?

• Is the site designated as a Hazardous Waste Site or have other hazards been identified or suspected, such

as H

S, Methane, or other chemicals? If so, are proper procedures for working in these environments in

place, including proper training of employees and certification of safety equipment?

• Is there a danger of lightning strikes? This subject must be addressed regardless of time of year or

current weather conditions.

• MSDS sheets must be on hand for all materials and chemicals brought to the site.

3.5 - Confirmation Activities for Clearances and Borehole Positioning

3.5.1 - Permits

Copies of all necessary permits will be provided to the Lead Driller or Acting Lead Driller, and any further

information relevant to the drilling operation.

It is the driller’s responsibility to verify the necessary permits have obtained and it is safe to drill.

Based on either site conditions or the planned ground disturbance activities, to ensure the safety of all on-

site personnel and subsurface structure integrity, consideration should be given to locking out selected site

utilities or temporarily shutting down a portion of or the entire facility.

3.5.2 – Markings

• Complete utility location prior to drilling [One Call: 811 or your local utility locating service] and

coordinate with the drilling contractor and site personnel.

• Mark locations in white.

• Field verify utility locations.

• Document all utility locates on a plot plan or other map of the site.

• Observe the area for indications of utilities.

• Hand dig if questions remain or if required by the property owner.

• Refer to your specific Utility Clearance and Isolation procedure.
