Section 470. Part B permit application for solid waste disposal facilities

Part B permit application requirements for all solid waste disposal facilities regulated under Part III (9VAC20-81-100 et seq.) are contained in this section. The Part B applications shall include the following requirements and documentation:

A. Plans submitted as part of the Part B application shall include the following:

1. Design plans. Design plans shall be certified by a professional engineer and shall consist of, at least, the following:

a. A title sheet indicating the project title, who prepared the plans, the person for whom the plans were prepared, a table of contents, and a location map showing the location of the site and the area to be served.

b. An existing site conditions plans sheet indicating site conditions prior to development.

c. A base grade plan sheet indicating site base grades or the appearance of the site if it were excavated in its entirety to the base elevation, before installation of any engineering modifications or the beginning of any filing.

d. An engineering modification plan sheet indicating the appearance of the site after installation of engineering modifications. More than one plan sheet may be required for complicated sites. This plan is required only for those sites with engineering modifications.

e. A final site topography plan sheet indicating the appearance of the site, and final contours of the site at closing including the details necessary to prepare the site for long-term care.

f. A series of phasing plan sheets showing the progression of site development through time. At a minimum, a separate plan shall be provided for initial site preparations and for each subsequent major phase or new area where substantial site preparation must be performed. Each such plan shall include a list of construction items and quantities necessary to prepare the phase indicated.

g. A site monitoring plan showing the location of all devices for the monitoring of leachate production, groundwater quality, and gas production and venting. This plan shall include a table indicating the parameters to be monitored for the frequency of monitoring before and during site development. The groundwater monitoring plan shall include information as applicable under 9VAC20-81-250 or 9VAC20-81-260.

h. A series of site cross-sections shall be drawn perpendicular and parallel to the site base line at a maximum distance of 500 feet between cross-sections and at points of grade break and important construction features. The location of the cross-sections shall be shown on the plan sheets and the section labeled using the site grid system. Where applicable, each cross-section shall show existing, proposed base and final grades; soil borings and monitoring wells that the section passes through or is adjacent to; soil types, bedrock and water table; leachate control, collection, and monitoring systems; limits of filling for each major waste type; drainage control structures; access roads and ramps on the site perimeter and within the active fill area; the filling sequence or phases; and other site features.

i. Detailed drawings and typical sections for drainage control structures, access roads, fencing, leachate and gas control systems, and monitoring devices, buildings, signs, and other construction details.

j. Plan sheets shall include:

(1) A survey grid with base lines and bench marks to be used for field control.

(2) Limits of filling for each major waste type or fill area.

(3) All drainage patterns and surface water drainage control structures both within the actual fill area and at the site perimeter. Such structures may include berms, ditches, sedimentation basins, pumps, sumps, culverts, pipes, inlets, velocity breaks, sodding, erosion matting, or other methods of erosion control.

(4) Ground surface contours at the time represented by the drawing. Spot elevations shall be indicated for key features.

(5) Areas to be cleared and grubbed and stripped of topsoil.

(6) Borrow areas for liner materials, gas venting materials, berms, roadway construction, daily cover, and final cover.

(7) All soil stockpiles including daily and final cover, topsoil, liner materials, gas venting materials, and other excavation.

(8) Access roads and traffic flow patterns to and within the active fill area.

(9) All temporary and permanent fencing.

(10) The methods of screening such as berms, vegetation, or special fencing.

(11) Leachate collection, control, storage, and treatment systems that may include pipes, manholes, trenches, berms, collection sumps, storage units, pumps, risers, liners, and liner splices.

(12) Gas, leachate, and groundwater monitoring devices and systems.

(13) Severe weather solid waste disposal areas.

(14) Support buildings, scale, utilities, gates, and signs.

(15) Special waste handling areas.

(16) Construction notes and references to details.

(17) Other site features.

2. Closure plan. A detailed closure plan shall be prepared and submitted. Such a plan shall be prepared in two parts, one reflecting those measures to be accomplished at the midpoint of the permit period, and the other when the useful life of the landfill is reached. The plan shall show how the facility will be closed to meet the requirements of 9VAC20-81-160 and 9VAC20-81-170, or 9VAC20-81-800. The plan shall include the procedures to be followed in closing the site, sequence of closure, time schedules, final plans of completion of closure to include final contours, and long-term care plan sheets showing the site at the completion of closing and indicating those items anticipated to be performed during the period of long-term care for the site. The plans shall include a table listing the items and the anticipated schedule for monitoring and maintenance. In many instances this information can be presented on the final site topography sheet.

3. Postclosure plan. A postclosure care plan shall contain long-term care information including a discussion of the procedures to be utilized for the inspection and maintenance of: run-off control structures; settlement; erosion damage; gas and leachate control facilities; monitoring for gas, leachate, and groundwater; and other long-term care needs.

B. A design report shall be submitted, which shall include supplemental discussions and design calculations, to facilitate department review and provide supplemental information including the following information:

1. The design report shall identify the project title; engineering consultants; site owner, permittee and operator; proposed permitted acreage; hours of operation; wastes to be accepted; site life; design capacity; and the daily disposal limit. It shall also identify any variances desired by the applicant.

2. A discussion of the basis for the design of the major features of the site, such as traffic routing, base grade and relationships to subsurface conditions, anticipated waste types and characteristics, phases development, liner design, leachate management system design, facility monitoring, and similar design features shall be provided. A list of the conditions of site development as stated in the department determination of site feasibility and the measures taken to meet the conditions shall be included. A discussion of all calculations, such as refuse-cover balance computations, stockpile sizing estimates, estimate of site life, and run-off and leachate volume estimates shall be included. The calculations shall be summarized with the detailed equations presented in an appendix.

3. Specifications, including detailed instructions to the site operator for all aspects of site construction.

a. Initial site preparations including specifications for clearing and grubbing, topsoil stripping, other excavations, berm construction, drainage control structures, leachate collection system, access roads and entrance, screening, fencing, groundwater monitoring, and other special design features.

b. A plan for initial site preparation including a discussion of the field measurements, photographs to be taken, sampling and testing procedures to be utilized to verify that the in-field conditions encountered were the same as those defined in the feasibility report, and to document that the site was constructed according to the engineering plans and specifications submitted for department approval.

C. Financial assurance documentation. When required by the Financial Assurance Regulations of Solid Waste Disposal, Transfer, and Treatment Facilities (9VAC20-70), the applicant shall provide the completed documentation to demonstrate compliance with those regulations; proof of financial responsibility must be for the entity identified in accordance with 9VAC20-81-450 B 10.

D. DEQ Form SW PTB (Part B Permit Application Form). The applicant shall submit a completed DEQ Form SW PTB.
