disposition of the decontamination facility should also be addressed. The contractor should be required
to submit a plan as part of the Site Health and Safety Plan, which describes vehicle, equipment, and
personnel decontamination procedures.
(2) Design Criteria. The decontamination facility typically has 150300 mm (612 in.) of
granular material underlain by a protective geotextile and a geomembrane 1.0 mm (40 mils) in thickness.
More elaborate designs may be used if the decontamination facility will be operated for a significant
period of time. To minimize the volume of decontamination water, a temporary cover should be used to
shed rainfall when the facility is not in use. Rinsate water is collected by gravity into a polyethylene or
precast concrete storage tank, which is typically about 3 m3 (100 ft3) in volume. Treatment and
disposal of the rinsate water and sediments should be in accordance with all state and Federal
regulations. See EP 200-1-2 for more detailed information on this subject.
d. Security Fencing. Chainlink security fencing is often used at the landfill boundary. The fence
normally has a standard single outrigger holding three strands of barbed wire. The fence fabric should
be a minimum of 1.8 m (6 ft) in height.
e. Demolition. Structures that will be demolished and debris that will be removed should be
identified on the contract documents. Transportation and disposal regulations must be considered if
demolition materials or debris contain hazardous waste. It may be possible to place the debris under
the landfill cover.
B-6. Health and Safety.
a. General. An industrial hygienist is responsible for the health and safety issues of a final cover
design. Elements to be addressed include the following: site description and contamination
characterization; hazard/risk analysis; staff organization, qualifications, and responsibilities; training;
personal protective equipment; medical surveillance; exposure monitoring/air sampling; standard
operating safety procedures; site control measures; personal hygiene and decontamination; equipment
decontamination; emergency response and contingency procedures; and record-keeping.
b. Design Criteria. Detailed safety and health requirements are described in ER 385-1-92. A
Health and Safety Design Analysis should be included as a chapter of the project design analysis to
describe the decision logic for safety and health requirements, which will be specified. Guide
Specification CEGS-01351 should be edited based on the design analysis and included in the contract
documents.
B-7. Chemistry.
a. General. Requirements for chemical sampling and analysis conducted during the construction or
maintenance phase of the project, such as general air quality, off-gas testing, leachate, borrow soil,
ground water, and miscellaneous testing for potential hazardous waste, should be prepared by the
B-33
