YADKIN COUNTY TRANSFER STATION
CLOSURE PLAN
and to fill the tanks with flowable fill once cleaned of leachate and residue. The leachate collection
system piping will be removed or filled, and drains will be filled with concrete to prevent
accumulation of stormwater in the piping and tank. In the event piping is removed, it will be
disposed of at the landfill. Costs are estimated to be approximately $10,000 to clean and fill the
small tanks and oil/water separator in place, and plug or remove the leachate collection drain and
piping.
Administration costs, if performed by a contracted firm as opposed to County staff, and assuming
20 hours of project oversight per week for six (6) months may range from $45,000 - $65,000.
Travel time and per diem costs will drive up the administration costs by approximately $10,000 -
$20,000. This estimate is inclusive of providing the required notification to the NCDEQ, arranging
for various contractors including bid solicitation and contractor selection, and overseeing the
closure activities. Costs may be less depending upon the staff level used for the project oversight,
the actual amount of time needed on sight, and the amount of travel and per diem needed.
Administration costs therefore, range from $55,000 - $85,000. For the purposes of closure, an
estimate using the lower amounts for travel and per diem suggests the administration costs would
be $55,000.
Closure cost estimates associated with post closure care monitoring and/or corrective action are
not provided. In the event post closure care monitoring and corrective action is required by the
DWM, costs will be revisited as required to ensure financial assurance requirements are
maintained, and the closure plan will be modified to include post closure care requirements.
Estimated costs associated with the closure of the facility include the following:
1. Mobilization/demobilization - $1,750
2. Pressure Washing -
$10,000
3. Leachate Disposal -
$1,500
4. Leachate Collection System -

5. Signage -

E. Post Closure Care

surface water monitoring, or corrective action at this facility in accordance with 15A NCAC 13B
