SECTION III - SUGGESTED STEPS TO ASSURE EQUAL EMPLOYMENT oPPoRiu'MTfeS'
1. COMPANY POLICY . , r ! r,
' , c"
, 1..2: I:. "t
Determine your company's policy regarding equal employment opportunities, Document th~'policy and post
, .
it in a conspicuous place so that it is known to all your employees. Furthermore, dissemifl'i',tS;the policy to all
potential sources of employees and to your subcontractors asking their cooperation. -the pdlicy statemerlt'.\
should recognize and accept your responsibility to provide equal employment opportunity in all your
employment practices, In regard to dissemination of this policy, this can be done, for example, through the
use of letters to all recruitment sources and subcontractors, personal contacts, employee meetings, web
page postings, employee handbooks, and advertising,
2. EQUAL EMPLOYMENT OPPORTUNITY OFFICER
Designate an equal employment opportunity officer or, at minimum, assign someone the responsibility of
administering and promoting your company's Equal Employment Opportunity program, This person should
have a position in your organization which emphasizes the importance of the program.
3. INSTRUCT STAFF
Your staff should be aware of and be required to abide by your Equal Employment Opportunity program, All
employees authorized to hire, supervise, promote, or discharge employees or are involved in such actions
should be trained and required to comply with your policy and the current equal employment opportunity
laws.
4, RECRUITMENT
(a) Let potential employees know you are an equal opportunity employer. This can be done by
identifying yourself on all recruitment advertising as "an equal opportunity employer".
(b) Use recruitment sources that are likely to yield diverse applicant pools. Word-of-mouth recruitment
will only perpetuate the current composition of your workforce. Send recruitment sources a letter
annually which reaffirms your commitment to equal employment opportunity and requests their
assistance in helping you reach diverse applicant pools,
(c) Analyze and review your company's recruitment procedures to identify and eliminate discriminatory
barriers.
(d) Select and train persons involved in the employment process to use objective standards and to
support equal employment opportunity goals,
(e) Review periodically job descriptions to make sure they accurately reflect major job functions. Review
education and experience requirements to make sure they accurately reflect the requirements for
successful job performance,
(f) Review the job application to insure that only job related questions are asked, Ask yourself "Is this
information necessary to judge an applicanfs ability to perform the job applied for?" Only use
job-related tests which do not adversely affect any particular group of people,
(g) Monitor interviews carefully, Prepare interview questions in advance to assure that they are only job
related, Train your interviewers on discrimination laws. Biased and subjective judgments in personal
interviews can be a major source of discrimination,
(h) Improve hiring and selection procedures and use non-biased promotion, transfer and training
policies to increase and/or improve the diversity of your workforce representation. Companies
must make sure procedures for selecting candidates for promotion, transfer and training are
based upon a fair assessment of an employee's ability and work record. Furthermore, all
companies should post and otherwise publicize all job promotional opportunities and encourage
all qualified employees to bid on them.

1. The surface on which the geotextile is to be placed will be graded to the neat lines
and grades as shown on the plans, The surface will be reasonably smooth and free
of loose rock and clods, holes, depressions, projections, muddy conditions and
standing or flowing water,
B. Placement
1. Prior to placement of the geotextile, the soil surface will be inspected for quality of
design and construction. The geotextile will be placed on the approved surface at
the locations and in accordance with the details shown on the plans. The geotextile
will be unrolled along the placement area and loosely laid (not stretched) in such a
manner that it will conform to the surface irregularities when material is placed on
or against it. The geotextile may be folded and overlapped to permit proper
placement in the designated area,

otherwise specified on the plans or by the manufacturer), and secured against the
underlying foundation material. Securing pins, approved and provided by the
geotextile manufacturer, shall be placed along the edge of the panel or roll material
to adequately hold it in place during installation. Pins will be steel or fiberglass

Steel washers will be provided on all but the "U" shaped pins, The upstream or up-
slope line will be inserted through both layers along a line through approximately
the midpoint ofthe overlap, At horizontal laps and across slope laps, securing pins
will be inserted through the bottom layer only. Securing pins will be placed along
a line approximately 2 inches in from the edge of the placed geotextile at intervals
not to exceed 12 feet unless otherwise specified, Additional pins will be installed
02270-2
as necessary and where appropriate, to prevent slippagti"or' rri~~l:ii\ent of the
geotextile. The use of securing pins will be held to the minimum 'necessary, Pins
are to be left in place unless otherwise specified, 111 F' ">,1 -

geotextile being used, overlapping the existing geotextile, Geotextile panels joined
by overlap will have the patch extend a minimum of 2 feet from the edge of any
damaged area,
4, The geotextile will not be placed until it can be anchored and protected with the
specified covering within 48 hours or protected from exposure to ultraviolet light.
In no case will material be dropped on uncovered geotextile from a height greater
than 3 feet.
