checklist of design activities is presented in Table 4-2-6A, to aid in
planning the design effort.  These activities are listed in their general
order of performance, but the order can vary considerably from site to site
and from jurisdiction to jurisdiction, depending on specific conditions.
4.2.5.29 As shown in Table 4-2-6A, initial tasks consist of compiling
existing information and generating new information on solid waste
characteristics and site conditions.  A listing of possible sources for
existing information is shown in Table 4-2-6B.  A summary of methods to obtain
new information is shown in Table 4-2-SC.
4.2.6.30 Throughout the design phase, it is advisable to periodically
contact regulatory agency representatives to ensure that the design will meet
any new requirements and procedures for permit application submittals.  (A
sample of documentation requirements for the State of Virginia Is included in
Appendix A.)  Maintenance of close liaison with state and local regulatory
officials throughout the design effort is normally helpful in securing a
permit without excessive redesigns, especially at a time when environmental
protection legislation and regulations are rapidly changing.
Two general types of design packages are prepared for a sanitary landfill:
1.
Conceptual (preliminary) design plan
2.
Construction design plan and specifications.
4.2.6.31 Conceptual design plans normally consist of the following
elements provided in sufficient detail to describe proposed filling plans to
regulatory agencies and the public.  The conceptual design can also serve as a
guide for landfilling operations in the event that design construction
drawings are not required.
1.
Conceptual design plans include:
a. An installation map showing existing site conditions.  The map
shall be of sufficient detail, with contour intervals of 1 ft to 5
ft and a scale of 1 in. = 50 ft to 1 in. = 200 ft, depending on
the steepness of the terrain and size of the landfill,
respectively.
b. A site preparation plan locating the areas and depths designated
for cover soil excavation and soil stockpile deposits.  Also shown
are site facilities locations such as structures, access roads,
and utilities.
c. Development plans showing final filling and excavation contours.
Development plans shall show interim (4- to 6-year) filling and
excavation contours if a long-lived site is planned.
d. Elevations showing cross sections to illustrate excavation and
landfill surface development at several locations across the fill.
Cross sections shall be prepared for each phase of the development
plan (i.e., interim and final).
