(c) A list of any other changes made by the owner or operator that do not need Ohio EPA concurrence but that affect construction or the record drawing.

[Comment: The listing of these changes is for Ohio EPA's informational purposes only.]

(3) Record drawings of the constructed facility components showing the following:
(a) Plan views showing the grades of the following, as appropriate:
(i) The limits of excavation.

(ii) The bottom of the recompacted soil liner or barrier layer.

(iii) The top of the recompacted soil liner or barrier layer.

(iv) The configuration of the leachate management system and the top of the drainage layer.

(v) The limits of emplaced waste.

(vi) The top of the cap system.

(vii) The surface water management system.

(viii) Access roads.

(b) Plan view of the location of ground water control structures, if applicable.

(c) Plan views of the deployment of the flexible membrane liner panels and the locations of and identification of the destructive tests and all repairs.

(d) Cross sections of the phase at closure taken at the same locations and using the same scale as in the approved permit to install or at an interval no greater than every three hundred feet of length and width that show the following:
(i) The limits of excavation.

(ii) The limits of emplaced waste.

(iii) Final grade including the cap system.

(e) Necessary details.

(4) For a scrap tire monofill facility, after the initial construction and establishment of the facility survey mark, the following information summarizing the activities performed to construct and establish the facility survey mark:
(a) The geodetic survey datasheet of each control point used to establish the horizontal and vertical coordinates of the survey mark.

(b) A table listing the horizontal and vertical coordinates of each control point and survey mark.

(c) A summary of surveying activities performed in determining the coordinates of the facility survey mark.

(d) A plan sheet clearly identifying the location of the survey mark, the control points, and the limits of waste placement on a road map with a scale of one inch equals no greater than one mile.

(e) A detailed drawing illustrating the design of the facility survey mark, as constructed.

(5) Documentation demonstrating that any oil or gas wells that have been identified within the limits of solid waste placement have been properly plugged and abandoned in accordance with Chapter 1509. of the Revised Code prior to any construction in the area of the well.

(6) Qualifications of construction, testing, and construction quality assurance and control personnel including a description of the experience, training, responsibilities in decision making, and other qualifications of the personnel that provided construction oversight and conducted all the testing on the engineered component for which the certification report is submitted.

(7) A signed statement that to the best of the knowledge of the owner or operator of the scrap tire monofill facility, the certification report is true, accurate, and contains all information specified paragraph (E) of this rule.

(I) Submergence facilities. The owner or operator of a scrap tire submergence facility shall comply with the following construction requirements:

(1) All construction requirements specified in this rule except the following:
(a) Paragraph (B)(6) of this rule.

(b) Paragraph (B)(11) of this rule.

(c) Paragraphs (F)(1)(e) and (F)(1)(f) of this rule.

(d) Paragraphs (H)(3)(a)(iv), (H)(3)(a)(v), and (H)(3)(d)(iii) of this rule.

(2) A flexible membrane liner may be placed on top of one of the options for a recompacted soil liner described in paragraph (B)(4)(k) of this rule.

(3) A flexible membrane liner that is placed on the recompacted soil liner or recompacted soil barrier layer and meets the following:
(a) Be sixty mil high density polyethylene (HDPE).

(b) Be an other material or thickness if the flexible membrane liner meets at a minimum the following:
(i) Be negligibly permeable to fluid migration.

(ii) Be physically and chemically resistant to chemical attack by the scrap tires, leachate, or other materials that may come in contact with the flexible membrane liner.

(iii) Have properties for installation and use that are acceptable to Ohio EPA.

(iv) Have a minimum thickness of forty mils.

(c) Be installed as follows:
(i) For installations exceeding ten thousand square feet, with at least one welding technician having seamed a minimum of one million square feet of flexible membrane liner present during installation.

(ii) Be seamed to allow no more than negligible amounts of leakage with seaming material that is physically and chemically resistant to chemical attack by the scrap tires, leachate, or other materials that may come in contact with the seams.

(iii) On a seaming area that is cleaned of deleterious materials immediately prior to seaming.

(iv) Be tested in accordance with the following, unless the manufacturer's specifications for testing are more stringent:
(a) For the purpose of testing every seaming apparatus in use each day, peel and shear tests performed on scrap pieces of flexible membrane liner at the beginning of the seaming period and every four hours thereafter.

(b) Nondestructive testing performed on one hundred per cent of the flexible membrane liner seams.

(c) Destructive testing for peel and shear performed at least once for every one thousand feet of seam length. An alternative means may be used if it is demonstrated to Ohio EPA that the alternative means meets the requirements of this paragraph.

(d) Electrical leak locations testing in accordance with ASTM D7002, ASTM D7703, ASTM D7240, or ASTM D7953 performed on one hundred per cent of the flexible membrane liner prior to initial backfill over the flexible membrane liner.

(e) Electrical leak locations testing in accordance with ASTM D6707 performed on one hundred per cent of the flexible membrane liner after initial backfilling over the flexible membrane liner.

(v) Be protected with a sixteen ounce liner cushion layer if the potential exists for the flexible membrane liner to come in contact with any sharp edged protrusions or any particles protruding more than one quarter of one inch. The liner cushion layer shall account for the weight of the overlying waste mass and have pre-construction interface testing performed according to paragraph (E) of this rule. If shredded tires are used in the leachate collection layer, a cushion layer consisting of sand, or other material with low puncture risk, a minimum of ten inches thick shall be used.

(4) Alternatives to the construction requirements in paragraph (B) of this rule may be used if it is demonstrated to the satisfaction of the director or the director's authorized representative that the alternative provides equivalent protection of human health, safety, and the environment.
