1. Closure. The termination of disposal
				  operations at a Class Two landfill, whether the entire landfill site or a
				  portion thereof, shall be in compliance with the following requirements.
a. Within one month following the last
				  receipt of solid waste at a site or a part of the site, the application of
				  final cover shall begin. A two foot thick final earth cover is required with at
				  least a 3% but not greater than 5% surface slope, graded to promote positive
				  drainage. The side slope cover shall not exceed three horizontal feet to one
				  vertical foot, i.e., a 3:1 slope. Alternate final cover designs may be
				  submitted for Department review and approval. Unless otherwise approved by the
				  Department, the application of final cover shall be completed within six months
				  of the last receipt of solid waste at the facility. The integrity of the final
				  cover shall be maintained.
b.
				  Testing for certification of cap closure by a South Carolina certified
				  professional engineer shall be done at a rate of four thickness tests per acre
				  as defined by best engineering and construction practices.
c. The storm water conveyance system for the
				  landfill shall be designed to ensure that the system is capable of handling a
				  24-hour, 25-year storm event during the active life and post-closure period of
				  the landfill.
d. The finished
				  surface of the disposal area shall be seeded with native grasses or other
				  suitable ground cover within 15 days of the completion of that portion of the
				  landfill.
e. Within 15 days of
				  closure of the entire landfill, the permittee shall post signs at the landfill
				  that state the facility is no longer in operation. On-site landfills are exempt
				  from this requirement.
f. Upon
				  closure of the entire or a portion of the landfill and within 30 days of
				  grading and seeding, pursuant to Section F.1.d. above, a professional engineer
				  licensed in the State of South Carolina shall submit to the Department
				  certification that the landfill has been properly closed in accordance with
				  requirements outlined in this Part and the facility's permit. Upon receipt of
				  certification of closure, the Department will schedule an inspection of the
				  facility. Upon issuance of the Department's final closure approval, the
				  Department's permit for this facility shall be modified to incorporate
				  post-closure activities.
g. Within
				  30 days of the Department's issuance of final closure approval, the owner
				  shall:
(1) Using a form approved by the
				  Department, record with the appropriate Register of Deeds a notation in the
				  record of ownership of the property - or some other instrument that is normally
				  examined during title search - that will in perpetuity notify any potential
				  purchaser of the property, that the land or a portion thereof, was used for the
				  disposal of solid waste. This notation shall define the final boundaries of the
				  waste disposal area including the latitude and longitude, and identify the
				  type, location, and quantity of solid waste disposed of on the property;
				  and,
(2) Submit to the Department:
(a) A plat showing the final boundaries of
				  the waste disposal area of the closed landfill; and,
(b) A copy of the document in which the
				  notation required by Section F.1.g. (1) above has been placed.
