020-3 Wyo. Code R. §§ 3-18 - Supporting Documentation/Appendices

(a) A USGS topographic map with a scale of 1:24,000 showing the proposed facility location or, if a 1:24,000 map is unavailable, USGS topographic map with a scale of 1:62,500 or another suitable topographic map.

(b) A map or aerial photograph of the area showing land ownership, land use, and zoning within one mile of the disposal site. The map or photograph shall be of sufficient scale to show all city boundaries, occupied dwelling, schools, hospitals, industrial buildings, water wells, water courses, roads, and other applicable details.

(c) A general facility plot plan (map) with a scale and contour intervals approved by the Administrator. The general facility plot plan shall at a minimum illustrate the following features:

(i) Landfill facility boundaries;

(ii) Points of access;

(iii) Location of soil borings and monitoring wells;

(iv) Location of proposed trenches or area fill locations;

(v) Working area/perimeter fire lane;

(vi) Working area/perimeter fence location; and

(vii) Locations of any facility buildings at the landfill.

(d) Additional facility plot plans at the same scale as the general facility plot plan, shall be submitted as necessary to show orderly development and use of the facility through the life of the site. These plot plans shall at a minimum contain the following information:

(i) Excavation plans for development of trenches or preparation of area fill locations;

(ii) Development of temporary surface water diversion structures which may be necessary to adequately control surface water run-on and run-off;

(iii) Access to active solid waste disposal areas, including development of internal roads;

(iv) Cover stockpile locations;

(v) Topsoil storage pile locations;

(vi) Litter screen placement information, if applicable;

(vii) Location of special waste management or disposal areas, if applicable; and

(viii) Other details pertinent to the development and use of the facility.

(e) A map showing proposed final post-closure contours prepared at the same scale as the general facility plot plan.

(f) If the industrial solid waste facility is included in a larger industrial property, a map that shows the facility boundaries in relation to the overall boundaries of the industrial property.

(g) Cross sections or drawing with sufficient specifications to describe:

(i) Internal litter catch screens or fences, if applicable;

(ii) Working area/perimeter fencing;

(iii) Access roads;

(iv) Trench or area fill method;

(v) Special waste areas, where appropriate;

(vi) Systems used for monitoring, collection, treatment, and disposal of leachate, if applicable;

(vii) Groundwater monitoring well design;

(viii) Methane gas venting and monitoring system, if applicable;

(ix) Surface and subsurface drain systems to control run-on, run-off and, inflow;

(x) All components of engineered containment systems, if applicable, which include, but are not limited to, liners, caps, and berms; and

(xi) Any other design details requested by the Administrator.

(h) Recordkeeping logs: A copy of the recordkeeping logs/forms that will be maintained during the operating life, closure, and post-closure maintenance period.
