(1.0 INTRODUCTION
Ecology and Environment, Inc. (E & E), with a business office at 6405 Metcalf, Cloverleaf Building
#3, Suite 404, Overland Park, Kansas 66202, has entered into an EPA Region 7 Superfund Technical
Assessment and Response Team Contract (START) (Contract No. 68-W6-0012) to furnish technical
assistance at uncontrolled hazardous substance facilities.
E & E is in the process of conducting a site investigation in Le Mars, Iowa, at the Le Mars Coal Gas
site. As part of this investigation it is necessary to install a monitoring well network of nested wells in
order to document the apparent source of contamination, and attribute potential municipal well
contamination to that apparent source. The installation of monitoring wells will facilitate the investigation’s
objectives.
The Le Mars Coal Gas site is located in Le Mars, Plymouth County, Nebraska (Appendix A: Figure
1: Site Location Map) within section 9, Township 92 North, Range 45 West. The site consists of a
contaminated ground water plume located beneath a mixture of commercial and residential properties in
the north-central to northwest portion of the city (Appendix A: Figure 2: Site Area Map with Proposed
Monitoring Well Locations). The primary contaminants are petroleum-related chemicals including BTEX
(benzene, toluene, ethyl benzene, and xylene) compounds and polynuclear aromatic hydrocarbons (PAHs).
Geoprobe™ borehole sampling of the shallow ground water (30-40 feet below ground surface [bgs])
has characterized a contamination plume migrating from the intersection of 4,h Avenue NE and 1st Street
NE to the west-northwest toward Central Avenue. Extensive subsurface soil sampling has shown that the
former manufactured gas plant (FMGP), located on the northwest corner of 4th Avenue and Is1 Street,
appears to be the source of this contamination. The subsurface soil contamination extends to the north of
an east-west railroad line (formerly the Illinois Central RR) and to the west of a north-south drainage ditch.
Previous investigations have identified ground water contamination in three shallow monitoring wells
installed at the site. Water samples collected from these wells have levels of benzene up to 160 parts per
million (ppm), toluene up to 46 ppm, naphthalene up to 18 ppm, phenol up to 34 ppm, and benzo(a) pyrene
up to 220 parts per billion (ppb). (Note: None of the proposed monitoring wells will be installed directly
beneath the source area.) Subsurface soils on the source property are contaminated with benzene and
naphthalene at concentrations in excess of 300 and 2,600 ppm, respectively.
BLM/JG/LKS„ 1-1 1583LMTZXX/0007002/exhibitl/F
The primary objectives of the monitoring well installation and sampling are to:
• Document the extent of shallow ground water contamination, previously delineated with Geoprobe™ temporary monitoring wells, with permanent shallow monitoring wells.
• Determine the vertical extent of ground water contamination northwest of the site with nested permanent monitoring wells established at three depths
• Characterize site geology based on logging of retrieved samples.
• Characterize site hydrogeology based on sample logging during well installation and on water levels andfslugitestssfollowing well installation.
• Determine the potential for contamination migrating from the site to the two municipal wells located less than Vi mile northwest of the site.

2.0 INFORMATION TO BIDDERS
Questions regarding specific aspects of the work to be performed should be directed to the attention
of the E & E Project Manager (PM) Bill Mehnert or Program Manager Bob Overfelt at (913) 432-9961.
Questions concerning contract procedures should be addressed to the E & E Subcontracts Manager Ed
Pfeiffer at (716) 684-8060 or the E & E Project Manager Bill Mehnert at (913) 432-9961.
Eleven monitoring wells will be installed at the site. All installed wells will be located northwest of
the site other than the upgradient background well (see Figure 2 in Appendix A). Proposed locations are
approximate and may be changed by the PM based on utility clearance and drilling rig access. The 11
monitoring wells will be installed at five locations throughout the site. At 3 of the 5 locations a shallow
(approximately 25-30 feet below ground surface [bgs]) monitoring well will be installed across the water
table. At all five locations an intermediate aquifer (approximately 50-70 feet bgs) monitoring well will be
installed above the most surficial and substantial fine-grained aquitard unit (i.e., base of the glacial/alluvial
aquifer). At 3 of the 5 locations (not necessarily the same as the shallow well locations), a deep (140-160
feet bgs) monitoring well will be installed within buried channel deposits composed of sand and gravel.
Those buried channel deposits may be an important future source of drinking water for the city of Le Mars.
Final depths of all monitoring wells will be determined by E & E on-site personnel based on information
obtained from logging retrieved lithologic samples.
All monitoring wells will be installed using a rotosonic drilling rig. A single rig, with a minimum of
three subcontractor personnel, will be required for the project. In addition, and at a minimum, an equal
volume of water must be retrieved from the well during development as was lost to the formation
during well drilling and installation.
Before the commencement of drilling work, E & E will conduct a site orientation session with E & E
and subcontractor personnel. The session will cover a general site description, site safety, investigation-
derived waste handling, and decontamination procedures. It is the subcontractor’s responsibility to have
enough personnel present at the orientation meeting to adequately cover any unanticipated crew member
changes. Coordination and scheduling of such training will be with the E & E PM. For each day of on
site work, all subcontractor personnel will also be required to attend a brief daily health and safety meeting
prior to commencement of work.
Currently, E & E anticipates to start drilling activities on-August 7, 2000 and continue to August 17,
2000. Subcontractor personnel will be required to provide adequate notification to E & E of any
BLM/JG/LKS.,- 2-1 1583LMTZXX/0007002/exhibitl/F
scheduling conflicts that would prevent work from being conducted in an expeditious manner. Once
project work has started subcontractor personnel and equipment must be committed to the project until
completion of the work or until released by E & E. Due to the nature of the work, the average work day
is anticipated to exceed eight hours. The subcontractor will be required to submit daily summaries of
the work completed and associated costs in writing to the E & E PM at the end of each day during
well construction, including an estimation of the amount of water lost to the formation for each
boring/well.

3.0 GEOLOGY AND HYDROGEOLOGY
The following information is being provided to the subcontractor so a determination regarding the
applicability of the Rotosonic drilling method to site geologic conditions can be made. Receipt of a signed
bid by E & E from the subcontractor represents acceptance of the proposed drilling method.
3.1 SOILS
The general classification of soil in the Le Mars, Iowa area is silty soils of the Ida-Galva Association.
This association consists mainly of gently sloping to very steep silty soils that are well drained. One soil
type, the Galva silty clay loam is present at the Le Mars Coal Gas site. This soil develops on stream
benches that are about 5 to 15 feet above the flood plain and have moderate permeability and slope ranges
from 0 to 2 percent.
3.2 GEOLOGY/HYDROGEOLOGY
The upland surface of Plymouth County, in northwest Iowa, consists of a gently undulating prairie
topography which descends gradually toward the southwest and is trenched by a number of valleys that
trend south-westward. The Le Mars area is within the Dissected Till Plains Section of the Central
Lowlands Physiographic Province. The following discussion on the area geology and hydrogeology is
illustrated in Appenix A: Figure 3: General Geologic/Hydrogeologic Column.
Water in the Le Mars area is derived from two distinct aquifers, a surficial aquifer and the Dakota
sandstone aquifer. The surficial aquifer consists of unconsolidated recent alluvium, outwash sand and
gravel and glacial drift deposits and sand and gravel deposits in buried channels. The recent alluvium,
which is confined to the principal river valleys, and buried channels beneath the north and west portions
of Le Mars constitute a valuable source of water. The entire sequence of unconsolidated material is
considered an aquifer because sand and gravel of various ages are likely interconnected.
The Cretaceous-aged bedrock material consists of the Graneros Shale and the Dakota Formation which
is divided into the Woodbury and Nishnabotna members. The Graneros Shale is the youngest bedrock
encountered within the Le Mars area; however, it is unlikely this unit exists beneath the site although it is
found to cap the bedrock high about 1 V2 miles northeast of the site. The Woodbury Member of the Dakota
Formation is composed of interbedded shale, sandstone and lignite. The maximum thickness of the
BLM/JG/LKS 3-1 1583LMTZXX/0007002/exhibit 1/F
Woodbury Member is approximately 170 feet with post-Cretaceous erosion reducing this to approximately
70 feet beneath the buried channel. The Nishnabotna Member is composed of sandstones with some
interbedded shales and is approximately 250 feet in thickness. It is the Nishnabotna Member that comprise
the Dakota Aquifer in the area.
The Dakota Formation unconformably overlies the Ordovician Galena, Decorah, Platteville and
Glenwood Formations, which predominantly consist of shales and dolomites and constitute an aquitard
between the underlying St. Peter Sandstone and the Dakota Formation. In turn, these Ordovician units
unconformably overlie undifferentiated Cambrian and Pre-Cambrian rocks.
Regionally, the Dakota aquifer can be confined by the Woodbury Member shales, and younger
Cretaceous marine shales and limestones. Available city well logs indicate the Woodbury shales would
be a confining unit in the Le Mars area. The thickness of these Cretaceous units is highly variable because
of erosional dissection and complex facies relationships in the Dakota (Woodbury Member) shales and
sandstones. The glacial drift can also act as a confining unit of the Dakota aquifer in Plymouth County,
although the lack of lateral homogeneity is more likely to create perched ground water zones.
The nearest drinking water wells to the site are the Le Mars Municipal Well Nos. 4 and 8 (Figure 2),
located about one-half mile northwest of the site. The well depths of Municipal Well Nos. 4 and 8 are 313
feet and 371 feet, respectively. The two wells are located downgradient from the site relative to surficial
ground water flow and are both screened in the Dakota Formation (Nishnabotna Member). A
potentiometric surface map for the Dakota Aquifer indicates a southwest ground water flow.
It was discovered during the installation of the three Geotek monitoring wells that shallow ground water
flow appears to be in a north-northwest direction toward Willow Creek and the Floyd River. However,
during the E & E/START site inspection (SI) in February 1997, static water level measurements were
obtained from the three Geotek monitoring wells. These measurements indicated that shallow ground water
flow was trending in a more westerly direction toward the onsite buried drainageway with depths to
groundwater ranging from 12.6 feet bgs in MW-3 to 15.2 feet bgs in MW-1. In addition, a water table
map for the Surficial Aquifer along the entire Floyd River Basin indicates a west-southwest flow.
BLM/JG/LKS-,.. 3-2 1583LMTZXX/0007002/exhibit 1/F
4.0 SCOPE OF WORK
The subcontractor is to furnish all materials, equipment, and labor necessary for the drilling, sampling,
construction, and installation of 3 shallow, 5 intermediate, and 3 deep monitoring wells to total depths of
approximately 30, 70, and 160 feet bgs, respectively. The 11 monitoring wells will be installed at 5'locations throughout the site using a rotosonic drilling rig. In addition, the subcontractor Will provide
flush-mount surface protection and dedicated bladder pumps for each installed monitoring well.
Only clean, potable water may be used as wash or cooling water when drilling or flushing wells. It
is the subcontractor's responsibility to locate a source of clean water for all drilling and well
installation procedures. If drilling water is obtained from the city of Le Mars, the subcontractor must
ensureWeontaminatidnf E & E will not reimburse expenses incurred in the maintenance of an adequate water
supply.
4.1 MONITORING WELL DRILLING PROCEDURES
All 11 proposed monitoring wells will be installed using a rotosonic drilling rig with an accompanying
support vehicle(s). Proposed locations are shown in Figure 2 (Appendix A). The monitoring wells will
be installed in a highly developed residential and commercial area. Therefore, the physical arrangement
of the rotosonic drilling rig relative to its support vehicle(s) may vary depending on access.
Because of the granular nature of the sediment and the relatively shallow water table, the
subcontracted drilling team should be prepared to encounter and remedy the problem of heaving sands.
The subcontractor will inform the on-site E & E geologist of the quantity of water introduced to the
subsurface.
In general, all drilling and sampling operations shall conform to applicable standards specified by the
American Society for Testing and Materials (ASTM) and State of Iowa regulations..
4.1.1 Shallow Monitoring Wells
Three shallow monitoring wells will be installed at three separate locations. These wells will be
screened across the water table, which lies approximately 15 feet BGS. For costing purposes the
completion depth is considered to be approximately 30 feet bgs.
BLM/JG/LKS. 4-1 1583LMTZXX/0007002/exhibitl/F
All shallow monitoring wells will be drilled/sampled using a dual line of drill pipe. The inner 4-inch
(nominal) core barrel and rod will be advanced ahead of the outer 6-inch (nominal) casing. The outer
casing will then be advanced to the sampled depth and the inner rod and core barrel (with sample) will be
retrieved. As the continuous samples are retrieved from the borings, they shall be delivered to E & E field
personnel in plastic sleeves for sample extraction and geologic logging. The subcontractor will provide
a tray or table on which the soil cores can be examined and sampled. Continuous sample collection will
proceed in this manner to the final|depM^p|f^Riffi^Sn@ufilessIotheiiSVisgpe®5nilSd?l^lK|El^S
4.1.2 Intermediate Monitoring Wells
Five intermediate monitoring wells will be installed at each of the five locations. These wells will be
screened at the base of the shallow glacial/alluvial aquifer, which for costing purposes is considered to be
approximately 70 feet bgs. With the exception of the termination depth, the method of sample retrieval
and drilling is anticipated to be identical to that used for the installation of the shallow monitoring wells;
however, the subcontractor will be prepared to utilize 8-inch (nominal) and 9-inch (nominal) outer casing
in order to isolate anyjsuBstontlallclavglaversiabove the base of the shallow unconfined glacial/alluvial
aquifer.
4.1.3 Deep Monitoring Wells
Deep monitoring wells will be installed at three of the five monitoring well locations. The deep
monitoring wells will be screened within the buried channel aquifer previously described. Completion
depths of the deep monitoring wells are anticipated to be approximately 160 feet bgs. Because of the
possibility of transferring contaminated ground water from the glacial/alluvial to the buried channel aquifer,
override casing will be required. If no override casing is required to reach the bottom of the
glacial/alluvial aquifer, then 8-inch (nominal) override casing will be used to isolate the glacial/alluvial
aquifer from the buried channel aquifer. In the event that 8-inch override casing is needed in the
unconfined aquifer, 9-inch override casing will be driven over the 8-inch casing to the clay layer in the
unconfined aquifer and the 8-inch override casing will then be driven to the confining layer between the
shallow unconfined aquifer and the semi-confined buried channel aquifer. In the case that another
intervening fine-grained unit was encountered, 10-inch overide casing will be incorporated into the override
casing/drilling scheme. The annular space of all override casings must be seated with bentonite before
sampling/drilling proceeds.
BLM/JG/LKS... 4-2 1583LMTZXX/0007002/exhibitl/F
4.2 MONITORING WELL CONSTRUCTION AND INSTALLATION
The shallow, intermediate, and deep monitoring wells shall be installed to approximate depths of 30,
70, and 160 feet bgs. The final depth of completion at each monitoring well location shall be determined
by the E & E PM. This decision will be based on the depth to ground water and field observations for the
shallow wells and on lithology and field observations for the intermediate and deep wells.

1 INTRODUCTION
This document is meant to be used in conjunction with E & E SOPs for field operations and hazardous waste site operations, and incorporates by reference all the safety precautions required therein. It specifically addresses the functions and responsibilities of
personnel working on or around drilling operations.
E & E personnel are frequently required to work in the field with drill rigs, taking soil and rock samples, installing piezometers, and monitoring wells. Two general situations discussed separately are the supervision of Subcontract Drillers by E & E, and the direct operation of E & E's own drill rig by our personnel.
2 OPERATION OF DRILLING EQUIPMENT BY E & E
2.1 RESPONSIBILITIES AND AUTHORITY OF SITE SAFETY OFFICER
The duties of the Site Safety Officer (SSO) on drilling sites are the same as in other types of operations with the exception of the increased emphasis on the hazards unique to drilling work. This section details specific drilling concerns of an SSO.
E & E personnel are restricted from the borehole area during active drilling. When E & E personnel are doing drilling, they will be restricted from the borehole area by means of a "super exclusion zone" delineated by placing a 4- by 8-foot sheet of plywood over the borehole.
2.2 RESPONSIBILITIES AND AUTHORITY OF E & E DRILLER
At the beginning of each work day, the E & E driller must inspect the rig to ensure the following components have been properly inspected, maintained, or replaced, or procedures have been performed:
o Kill switches tripped and operation verified;
o Chain guards in place; o Belt guards in place; o Belts set to proper tension (visual); o Loose belts;o Presence of any fluid leaks; o Any damaged hoses, cables, ropes, chains; o Control panel is clean; o Control lever functions labeled; o Pressure relief valves function; o Cathead free of rust and grease; o Cathead grooves less than 1/8 inch in depth; o All tools in proper working order; o Rig leveled and stabilized; o Check for weld cracks in mast; and o Safety hooks operational.

The Driller will report items needing attention to the SSO; however, it is the Driller's responsibility to make sure that these items are corrected prior to drilling.
During the drilling operations, the following safety practices will be in effect:
o All wheels will be blocked.
o Rig will be leveled using jacks or stabilizers.
o Rig engine will be in neutral when not actively turning augers.
o Plywood (or suitable substitute material) "super exclusion zone" pad will be in place over borehole.
o Rig engine key will be properly labeled.
o Rig equipment will be kept in an orderly manner within drilling work zone.
o All equipment will be properly lubricated.
o Tools will be used only for their intended purpose.
o Safety glasses, hearing protection will be worn when hammers are operated.
o Jaws of all wrenches will be clean and free of mud to prevent slippage.
o All lift hooks will have jaw clasps.
o Fire extinguisher will be staged at rear of rig.
o Rig will not be moved when mast is in raised position.
o Cables and ropes will be tied back or secured on stabilizer
posts.
o All unattended drill holes will be covered.
o Check for overhead obstructions when raising rig mast, boom will not be raised within 25 feet of overhead utilities.
o No refueling will be permitted while equipment is running.

Revised:JANUARY 1990
The Driller has authority to direct personnel vithin the area while drilling operations are in progress. Access to the hazardous area around the auger and borehole is restricted by the "super exclusion zone" delineated by the 4- by 8-foot sheet of plywood centered over the borehole before drilling. A large hole cut in the plywood allows
penetration of the augers. No personnel are allowed in this zone pad at any time while drilling is actively underway.
Housekeeping around the rig is the responsibility of the Driller, but all team members must participate in this effort as well.
2.3 RESPONSIBILITY AND AUTHORITY OF OTHER E & E PERSONNEL
E & E personnel working at a drilling site must act as support to the Drilling Team by providing any necessary support functions; however, it is important that personnel are careful not to interfere with the drilling process. Personnel are restricted from approaching the "super exclusion zone" while drilling is underway. If an E & E crew member recognizes an unsafe condition in the work area or on the rig, he should bring it to the attention of the SSO and Team Leader, if it is not resolved in a timely manner. If conditions are still deemed to be hazardous, team members have the option to contact their Regional Safety Coordinator (RSC) or Corporate Health and Safety in Buffalo.
It is the responsibility of all E & E personnel to carry their issued nondisposable gear, including hard hat, face shield, respirator, steel-toed boots, eyepiece inserts, safety glasses, and appropriate outerwear for the expected climate.
All personnel should be aware of emergency facilities, egress routes, and special medical conditions of their team members. As with all E & E field work, the buddy system is to be enforced.
3 TRAINING REQUIREMENTS FOR SITE PERSONNEL
3.1 E & E SITE SAFETY OFFICER
In addition to Basic Health and Safety Training and other OSHA mandated training, first aid, CPR, and necessary training in field monitoring of personnel, an SSO should have previously worked as a team member on field drilling projects in order to have a working knowledge of the drill rig and its inherently hazardous nature. Vhere monitoring instrumentation is to be used, the SSO must be properly trained prior to field work. The SSO must have an understanding of the hazards of heat and cold stress, their associated symptoms, and proper work modifications to protect field staff from potential injury.

■- « s. T„»TNTNn 7.. 1Revised: JANUARY 1990 .
3.2 E & E DRILLER AND HELPER
The E & E driller and helper shall have taken and passed the basic 40-hour Health and Safety Training as prescribed by E & E and mandated by OSHA. They shall also meet the other minimum requirements for field work including medical approvals and respirator fit test. Based on previous experience and training, the Driller will be critiqued by the E & E Drilling Team upon employment with E & E, by performing various types of drilling. This review will be the basis for determining whether additional training or apprenticeship will be required before allowing this employee to act as Driller. An existing E & E employee shall have a minimum of 1 year experience as a Driller's Helper on an assortment of field projects before he or she can be reviewed for advancement to the position of Driller. If a Driller is uninvolved in drilling efforts for 1 year or more, he or she will be required to act as a Driller's Helper on a project, as well as receive rig-specific training on the equipment, before being permitted to act as a Driller again. The Driller's Helper position requires prior attendance at a drilling training school program. Following successful completion of such a course, the Driller's Helper will be observed on sites for a period of approximately 6 months, during which time he or she will work on several drilling projects performing assorted types of drilling. The E & E Drilling Team will determine, based on these field observations, whether additional training is required for this individual.
3.3 OTHER E & E DRILLING PERSONNEL
All E & E personnel shall have taken the basic 40-hour Health and Safety Training course. Field personnel must meet medical and respiratory fit test requirements established by E & E and OSHA, as
well.
3.4 SUBCONTRACT DRILLER AND OTHER SUBCONTRACT DRILLING PERSONNEL
Subcontract Drillers and their support personnel must, at a minimum, have passed basic 40-hour Health and Safety Training as prescribed by OSHA 29 CFR1910.120. They shall be medically approved and trained to use the level(s) of respiratory protection required onsite. Certification of training by the Subcontractor shall be required as a deliverable included in E & E's contractual documentation. This training shall be verbally verified and logged onsite by the SSO or Team
Leader before starting work.

4 SUPERVISION OF SUBCONTRACT DRILLERS
4.1 RESPONSIBILITIES AND AUTHORITY OF SITE SAFETY OFFICER
The responsibilities of the SSO at a drilling site where subcontracted drillers are used include the following: rig inspections,
personnel monitoring, and personnel protection.
A rig inspection starts with, but is not limited to, verifying each
item on the following checklist:
o The mast must be located at least 25 feet from any overhead or
underground utility lines.
o The location and operation of operational and unencumbered kill svitches must be reiterated to all site personnel.
o Outriggers, stabilizers, or jacks are in place, and the rig is
level.
o A geophysical survey (electromagnetic or ground-penetrating radar) or a reliable site history must be obtained to verify
absence of buried obstacles, tanks, or drums.
o A first aid kit and filled eyewash must be readily available.
A fire extinguisher should be charged to the proper pressure and
staged at rear of rig during drilling.
o The condition of ropes, chains, and cables must be checked.
o A lifeline or safety belt must be available if mast climbing is
necessary.
o The Site Safety Plan (SSP) must be posted with emergency phone
list and map of hospital route.
o A "super exclusion zone" must be established around theborehole, using a 4- by 8-foot sheet of plyvood. This defined area will be entered during active drilling only by the Driller,
except in emergency situations.
If any of these items need replacement or repair, the SSO must make necessary arrangements and later verify that repair or replacement is sufficient before actual drilling begins. Working together, the SSO and the driller should verify that the rig has been checked against the
Operator's checklist.

DRILLING RIG OPERATIONS
Revised: JANUARY 1990
The SSO's monitoring duties include calibration and setup of the appropriate monitoring devices, as specified in the SSP. At a minimum, this generally includes an O^/explosimeter and realtime organic vapor monitoring capabilities (e.g., HNU, OVA). Noise monitoring, like heat stress monitoring, is employed where appropriate. If the SSO believes additional monitoring devices beyond the directive of the SSP should be employed (e.g., Rad Mini, Mini Ram), it is his or her responsibility to obtain this equipment with the cooperation of the RSC or the Corporate Health and Safety Group, from the nearest E & E office.
It is the responsibility of the SSO to ensure that all safety equipment is in good working order. Day-to-day operations, as well as calibration data, must be recorded in the equipment log or SSO log. Adequate supplies such as breathing air, drinking liquids, and
calibration gas must be maintained.
E & E personnel are forbidden from entering the "super exclusion zone" around the borehole while the rig is actively drilling. The SSO must not attempt to take air readings in or around the auger while in use, nor are cutting samples taken while the auger is in motion. An O./explosimeter should be set up if possible for unmanned (alarmed) operations at the rig using an extension hose to continuously draw samples from the borehole area during drilling operations.
The SSO has the ultimate authority over the Subcontractor with regard to whether work practices meet the requirements of the SSP. Shutdown of work or restriction of personnel are options available to the SSO. The SSO should hold informal site safety briefings at the start of both field work and daily work shifts throughout the course of the project. Although E & E contractually requires Subcontractors to provide properly' trained and outfitted staff, the SSO should verify verbally at the start-up meeting that the field staff has necessary respiratory approval and OSHA-mandated training, especially on hazardous waste sites. Site safety briefing topics, as well as attendees, will be
recorded in the site safety log.
If the SSO has reason to believe either E & E or Subcontractor personnel are under the influence of alcohol or drugs, or are otherwise ill before or during work onsite, he or she should consider restricting those team members from site work. Personnel arriving for work requiring level C protection who are not cleanly shaved may also be
restricted at the discretion of the SSO.
The following is a list of basic topics to be covered at site
safety meetings:
o Personnel responsibilities;o Planned investigation and presumed potential hazards;o Levels of protection, monitoring plan, and equipment;o Emergency scenario plans, including kill switch use;
6
TKto: SOP-HEALTH AND SAFETY ON DRILLING RIG OPERATIONS
Category: H & s> training 2.7 Revised: JANUARY 1990
o Location and operation of kill switches, fire extinguisher, and
first aid kit;o Heat and cold stress hazards;o "Super exclusion zone" around borehole; ando Warnings to Subcontractors about hazards of climbing the mast
vithout safety belt and other equipment.
Because heat stress is a constant threat during warm weather, the SSO is responsible for determining whether conditions are unsuitable for work. Where workers cannot work with the assistance of work modifications, cooling vests, and other cooling means, the SSO may decide that work should not continue. The need for worker monitoring through blood pressure and oral temperature checks will be determined by the SSO with assistance from the RSC and Buffalo Health and Safety
staff, if necessary.
The SSO will be responsible for shutdown of the drilling operation
if electrical storms are in the site area.
No refueling operations will be performed until rig engines are shut down. Hotor fuels should be stored and dispensed from spring-loaded, OSHA/FM-approved gas cans constructed of metal or
polyethylene.
The SSO should ensure and document that no boreholes are left open or unfilled after drilling equipment is moved. In instances where a hole must be left open and unattended, suitable barricades, or the equivalent, will be staged around the hole to prevent personnel and
equipment from falling in.
4.2 RESPONSIBILITIES AND AUTHORITY OF OTHER E & E PERSONNEL
All E & E personnel on site are required to follow the terms of the SSP and the direction of the SSO. Because the SSO cannot be in all places at all times, the crew should observe the subcontractors and condition of their equipment at all times, and report immediately to the Team Leader and SSO any safety-related issues that are unresolved. Included are such details as dressout, site functions, and decontamination. It is important that the SSO be involved so that
proper log entries can be made.
E & E, as policy, does not provide safety equipment or monitoring instrumentation to subcontractors. Some projects, however, may be set up so that E & E personnel and subcontractors share the same expendable
supplies.
E & E personnel are forbidden from approaching augers during drilling. Activities at the borehole, such as sampling, require that
equipment be stopped.

5 GENERAL DRILLING SITE SAFETY CHECKLISTS
5.1 SAFETY CHECKLISTS FOR SPECIFIC TYPES OF DRILLING ACTIVITIES
5.1.1 General Drilling Site Safety Checklist
o All E & E drilling personnel will have read and understood the
terms of the E & E drilling SOP.
o Obvious or questionable safety,conditions that arise duringdaily inspection of the rig and its components will be cause for
work interruption.
o Only approved Drillers will remain in proximity to the borehole
during drilling, and an approximate 4- by 8-£oot "super exclusion area" will be established around the moving auger at all times. No personnel, except the Driller and the Driller's Helper, will enter this zone during drilling. The SSO will issue warnings to those personnel who breach this zone.
o Continuous 0-/explosimeter monitoring at borehole using remote
sampling hose will exist at all times.
o All field team members will be briefed on planned drilling operations and possible problems before work begins on day 1.All will be shown the location and operation of "kill switches,
which will be operationally checked each morning.
o Fire extinguisher(s) will be staged next to the rig before
drilling and refueling operations.
o Welding and cutting activities will only be performed away from
ignition sources at a distance approved by the SSO or Team
Leader.
o Appropriate personnel protective equipment (based on hazards
associated with assumed well contaminants) will be worn as directed by the SSO and the SSP. At a minimum, steel-toed boots, hard hats, and face shields will be worn during any
active drilling.
o Outrigger stabilizers must be in place before drilling \
commences, and the rig must also be leveled.
o The drill rig mast must be horizontal during movement of rig and
should not be erected within 25 feet of overhead lines.

o Electrical storms within hearing range of the job site will signal work termination until the SSO and Team: Leader notify
personnel otherwise.
o The local utilities should be contacted prior to drilling so that their lines can be located and flagged. Situations of close proximity may involve isolating utility lines (i.e.,
shutdown and inerting of gas lines).
o When buried drums or other material are suspected, a full survey of the drilling zone is required using appropriate
instrumentation prior to ground breaking.
o Only trained, experienced staff who have studied proper drilling methods and served as a Helper under an experienced Driller will
operate the cathead.
o Only properly licensed staff will drive the drill rig. A daily safety check of the vehicle, following E & E protocol, will be
carried out by the driver.
o Climbing on the vertical mast is not permitted by E & E staff. Because the boom is not equipped with a ladder, it should be
lowered for repairs.
5.1.2 Rotary and Core Drilling
The following precautionary measures should be taken during rotary
and core drilling:
o Rotary drilling tools should be safety checked prior to
drilling:
- Rods and bit should be open and clear.
- Water swivels and hoisting plugs should be lubricated and
checked for "frozen” bearings before use.
- Drill rod chuck jaws should be checked periodically and
replaced when necessary.
- The capacities of hoists and sheaves should be checked against the anticipated weight of the drill rod string, in
addition to other expected hoisting loads.
- All hoses to and from the pump should be checked for properly installed couplings; couplings should be secured with locking
devices on "quick connect" fittings or wire on
"Chicago-Style" couplings.

o Check the cathead periodically, when the engine is not running, for rope wear grooves. If a rope groove forms- to a depth greater than 1/8 inch (3 mm), the cathead should be replaced.
o Always use a clean, dry, sound rope. A wet or oily rope may "grab" the cathead and cause drill tools or other items to be
rapidly hoisted to the top of the mast.
o Should the rope "grab" the cathead or otherwise become tangled in the drum, release the rope and sound an appropriate alarm for all personnel, including the Operator, to rapidly back away and stay clear. If the rope "grabs" the cathead and tools are hoisted to the sheaves at the top of the mast, the rope will often break, releasing the tools. If the rope does not break, stay clear of the drill rig until the Operator can turn off the drill rig engine and initiate other appropriate actions to release the tools. The Operator should carefully watch the suspended tools, quickly backing away after turning off the
engine.
o Chemicals can cause deterioration of the rope that may not be visibly detectable, thus the rope should always be protected
from any chemical contact.
o Never wrap the rope from the cathead (or any other rope, wire rope, or cable on the drill rig) around a hand, wrist, arm, foot, ankle, leg, or any other part of the body.
o Always maintain a minimum of 18 inches of clearance between the operating hand and the cathead drum when driving samplers, casing, or other tools with the cathead and rope method. Be aware that the rope advances toward the cathead with each hammer blow as the sampler or other drilling tool advances into the
ground.
o Do not use more rope wraps than are required to hoist a load.
o Do not leave a cathead unattended with the rope wrapped on the
drum.
o Position all other hoist lines to prevent contact with the
operating cathead rope.
o When using the cathead and rope for driving or back-driving,make sure that all threaded connections are tight, while staying as far away as possible from the hammer impact point.1
o The cathead Operator must be able to operate the catheadstanding on a level surface with sound, firm-footing conditions,
without distraction or disturbance.

5.1.4 Continuous-Flight or Hollow-Stem Augers
o Prepare to start an auger boring with the drill rig level, the clutch or hydraulic rotation control disengaged, the transmission in low gear, and the engine running at low RPH.
o Apply an adequate amount of down pressure before rotation to seat the auger head below the ground surface.
o Check, auger flights for nicks or burrs that could catch clothing
during rotation, and file them down.
o Vatch the auger head while slowly engaging the clutch orrotation control, and start rotation. Stay clear of the auger.
o Slowly rotate the auger and auger head while continuing to apply down pressure. Keep one hand on the clutch or the rotation control at all times until the auger has penetrated about 1 foot
or more below ground surface.
o If the auger head slides out of alignment, disengage the clutch or hydraulic rotation control, and repeat the starting process.
o An auger guide should be considered to facilitate the starting
of a straight hole through hard ground or pavement.
o The Operator and tool handler should establish a system of responsibility for the various activities required for auger drilling, such as connecting and disconnecting auger sections and inserting and removing the auger fork. The Operator must ensure that the tool handler is well away from the auger column and that the auger fork is removed before starting rotation.
o Only use the manufacturer's recommended method of securing the auger to the power coupling. Do not touch the coupling or the auger with your hands, a wrench, or any other tool during
rotation.
o Whenever possible, use tool hoists to handle auger sections.
o Never place hands or fingers under the bottom of an auger section when hoisting the auger over the top of the auger section in the ground or other hard surfaces such as the drill
rig platform.
o Never allow feet to get under the auger section that is being
hoisted.

o When rotating augers, stay clear of the rotating auger and other rotating components of the drill rig. Never reach behind or
around a rotating auger.
o Use a long-handled shovel to move auger cuttings away from the auger. Never use your, hands or feet to move cuttings away from
the auger.
o Do not use hands to clean rotating augers when removing augers
from the ground.
o The use of wire line hoists, wire rope, and hoisting hardware should conform to stipulations developed by the American Iron and Steel Institute Wire Rope Users Manual.
5.1.5 Use of Wire Line Hoists, Wire Rope, and Hoisting Equipment
All wire ropes and fittings should be visually inspected during use and thoroughly inspected at least once a week for abrasion, broken wires, wear, reduction in rope diameter, reduction in wire diameter, fatigue, corrosion, damage from heat, improper weaving, jamming, crushing, bird caging, kinking, core protrusion, and damage to lifting hardware. All related equipment must conform to standards as established by the American Iron and Steel Institute Wire Rope Users Manual. Wire ropes should be replaced when inspection indicates excessive damage according to the Wire Rope Users Manual. All wire ropes which have not been used for a period of 1 month or more should be thoroughly inspected before being returned to service.
o End fittings and connections consist of spliced eyes and various manufactured devices. All manufactured end fittings and connections should be installed according to the manufacturer's instructions and loaded according to the manufacturer's
specifications.
o If a ball-bearing type hoisting swivel is used to hoist drill rods, swivel bearings should be inspected and lubricated daily to ensure that the swivel freely rotates under load.

o If a rod slipping device is used to hoist drill rods, do not drill through or rotate drill rods through the slipping device, and do not hoist the drill rod column higher than one-half the mast height above the top of the mast (derrick). Do not hoist a rod column with loose tool joints and do not make up, tighten, or loosen tool joints while the rod column is being supported by a rod slipping device. If drill rods should slip back into the borehole, do not attempt to brake the fall of the rods with hands or by tensioning the slipping device.

o Host sheaves on exploration drill rigs are stationary with a single part line. The number of parts of line should never be increased without first consulting with the manufacturer of the
drill rig.
o Wire ropes must be properly matched with each sheave—if the rope is too large, the sheave will pinch the wire rope—if the rope is too small, it will groove the sheave. Once the sheave is grooved, it will severely pinch and damage larger wire ropes.
o Use tool handling hoists only for vertical lifting of tools (except when angle hole drilling). Do not use tool handling hoists to pull objects away.from the drill rig; however, drills may be moved using the main hoist if the wire rope is spooled through proper sheaves according to the manufacturer's
recommendations.
o When stuck tools or similar loads cannot be raised with a hoist, disconnect the hoist line and connect the stuck tools directly to the feed mechanism of the drill. Do not use hydraulic leveling jacks for added pull to the hoist line or the feed
mechanism of the drill.
o When attempting to free a mired vehicle or drill carrier, use only a winch on the front or rear of the vehicle, and stay as far as possible away from the wire rope. Do not attempt to use tool hoists to pull out a mired vehicle or drill rig carrier.
o Hinimize shock loading on a wire rope—apply loads smoothly and
steadily.
o Avoid sudden loading in cold weather.
o Never use frozen ropes.
o Protect wire rope from sharp corners or edges.
o Do not operate the rig with damaged or faulty guides, rollers, sheave bearings, or latches on safety hooks.
o Clutches and brakes on hoists should be periodically tested.
o Know and do not exceed the rated capacity of hooks, rings, links, swivels, shackles, and other lifting aids.
